Randy here is what the moparts said my car should be making. But it says i should of ran a 10.90 in the 1/4 with (Your Rear Wheel Hp Is: 533.52) but in the cool fall air i ran a best of 10.68. So i don't know how right the program is. mopar65 :beer

675 flywheel according to my calc will get you 10.81 @ 124.5 at 3720 lbs.

Hi,Bobby! It says with my best of 120mph at 3720...it's making 502 at the rear wheels. Not sure what that translate to at the crank?
On Gary Jacob's dyno,it made 425 at the wheels!
That's a big difference!

My original 512 C.I. pump gas low deck made 612 HP at 5600 RPM and 644 Ft lbs at 4500 RPM. It ran 10.69 ET at 124.6 MPH at Woodburn corked up with the air cleaner on the six pak. That was with me in it weighing close to 3400 Lbs. wet, corked up with the air cleaner on, 4.10 gears with 30 inch tall tires
The torque converter can and does makes a huge difference on our cars
I ran the car at Woodburn several times this summer, it ran 9.96 at 134 MPH corked up on pump gas. This motor made 727 HP the last time it was on a DTS engine dyno at 4300 Ft elevation in Klamath Falls, OR
I broke my ten inch custom built converter two years ago, I put in a new T/A 8 inch race Hemi converter with no other changes, it made the car way easier to drive and race and pick my car up .2 ET and 2 MPH in the 1/8 mile

The few times I have run my #'s on a program they all seem to be close as it says I make about 600 to 625 at the flywheel to run 10.70's at just over 3700 lbs. Ron

Bingo! My duster with a 560HP 360 went 10.50's-10.60's at 127mph at 3360lbs. with me in it.
Just remember, engine acceleration is just as important as the HP and TQ the engine produces!!

I have made 468 - 500 at the rear wheels on different dynos ..but I have gone 10.67 at 125 with a racing exhaust and 4.10 gears.. to slow the car down I put 3.73's in and my full exhaust and MT drag radials and the car went ....10.67 at 122 lol
at 3750 with me ....you should see your first 10 !!!! at Norwalk and then some

Randy,
my Satellite on the dyno normally shows 405-410RWHP.
Best et is 11.09 normally runs .12-16 MPH is around 118.9-119.75
car weight last time weighed is around 3775lbs
i have a 5200 stall and with any stall you won't see a true hp.i will normally look at adding 15% puts it in the real ballpark.Means about 525-535FWHP
around 20-25HP should give you a tenth.If you get around 100FWHP over me
you may exceed your hopes
good luck
Tex

Randy our RR weighs 3700 with driver and with 615 hp on the dyno it ran 10.80's with street tires and exhaust to the rearend. It was no way all scienced out so I am sure it could have gone faster. It has a J conv, a 4.10 sure grip dana 60, full interior, etc.
The car usually ran 11.0's to 10.90's in normal air and cooler air it was faster. The 60' times were slow at 1.58 best but normal was 1.64's most of the time.

It will be interesting to see what it makes for power and what it runs. Mine is very similar at 3750 lbs. with me in it and runs a best of 10.63 @ 126 and normally runs 10.69 to 10.73. I have never had it on a dyno.

I normally run 28 x 14.50 Hoosier Quick time pro's I just ran the 275 60 Drag radials for a weekend but they did work good for me. My car is basically all stock 45 year old leaf springs some inexspensive gas shocks. It has a best 60' of 1.49 which Im sure could get better with some better suspesion parts. I was guessing mine makes 650 to the flywheel but could be off.

Trying to determine HP using ET is a crap shoot at best - so - using my trusty Moroso "power speed calculator", and pluging in 3700 lbs and 500 HP, I came up with an ET of 10.95.

He could probably do it with 520hp being that he doesnt
60ft real well.. but that would be about the minimum...
once he's rolling its fine... if he got the 60' down
to a 1.50s he could bump into the 10s now(barely)

Every time I see a question like this, my first instinct is always to reply "On whose dyno???" I ran 11.0s @ 121 w/ an engine that made 590 HP on one dyno, then ran 10.5s @ 126 w/ an engine that made 610 HP on a different dyno.

My 'Cuda runs 10.70's at 125,on the chassis dyno it made 495hp,my car weighs 3770 with me in it,has full length exhaust thru the Cuda tips,4.56 gear,28in tall tire,my car doesn't 60' very well,only 1.61/1.62..so obviously there's more there if I can get it to 60'.My runs were at Fontana Dragway,a little above sea level I believe.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/21/12 06:12 PM
IMO, Trying to use FWHP is a waste of time especially with an auto car.
There are guys out there that are getting 9-10% parasitic loss, some even less, out of their stuff and other are lucky to get 20%.
Watch "Pass Time" for a heavy dose of claimed high HP crummy running rides. Guys 3000# car makes 700 HP and runs 120mph... yeah sure it makes 700hp... LMAO Maybe it's got the worst converter in it known to man!
I'll stick with my 525 guess at the wheels, whether that take 575FWHP or 650... Who knows!
As mentioned the best time cutter you can get is chipping at the 60' number. If it goes 1.60 now, there's at least .10 in that, so maybe .2 off the big end.

My cuda went 10.40 at 129 mph at 3700# w/ 508 rwhp...on a Dynojet chassis dyno. On an engine dyno, that combo should have been somewhere around 620 hp.

Mike,the 440 liked your 850..and Brad's,and Russ' 950HP even more...at least at the track!
Brad,Gary Jacob's(Jake68)chassis dyno is a DynoJet. Rob,the GTX usually 60's in the 1.52-1.56 range. Do you guys agree with the 80-100 hp increase from the head work? I believe,if I can get decent traction..and run 1.49-1.50's,I could hit my 10.8-10.9 goal.
BTW..the engine dyno at St. Clair Engine,where I'll be running it,is a Stuska..which is a division of Power Test Inc. Anybody here know how accurate these are?
Thanks! Randy

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/21/12 08:11 PM
That's a pretty good 60'. Must have been something else that I saw about 1.60 time. The extra HP may help your 60's. If you hit 1.50 or better, the time you want should be in range.
Dynos, both chassis and engine, are all over the map, no consistency. Tuning tool, great; reality, not so much most of the time. And EVERYONE claims the dyno used was stingy!
Seen one where the engine alleged to make 560hp, 3200 pound car, ran 121-122. I'd be REALLY disappointed if that was my ride because something isn't right.
Good luck, should be fun!

Just to be sure, get the car to HOOK WELL first. It should hook with a good chassis setup and weight transfer (regardless of tire). The "degree"
of traction is in the tire pressure setting and/or
tire compound. Horsepower is great to get you in the 10's, BUT without good weight transfer or chassis setup you are not pulling a decent 60ft time off the the line. My guess on your HP to run
10.9 - 10.8 index would be the 550-565 hp (RWHP) range (car weight depending). Just my . Nice car and good luck on the reaching the 10-sec index.

Yep, a "Bad Chassis" eats HP!! Just like how your car "HATES" a Drag Radial. it's not the tire, It's that the chassis doesn't work. It's been proven may times, Drag Radials work well, with a good chassis.

I thought you had a 60' in the 1.6x.... according
to Shawn he thinks that dyno is close to real power
but is about 10-15 hp short(stingy) which I could
care less about 10-15 hp as long as its real

My chassis either works good or I am leaving some power on the table. Since my chassis is basically stock with stock type shocks and stock 45 year old springs I would assume it probly isnt working very good. What converter are you running in the GTX and what gear?

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/21/12 09:47 PM
LabRatt, I would suspect you will have plenty of power to get the job done. However, as has been the case in several of your last track outings, chassis prep and traction issues will be the key.
http://www.youtube.com/watch?v=gdDtz30-JJ8&feature=channel&list=UL You have plenty of tire, now get the chassis as dialed as the engine.
I know that in the past you haven't been too keen on the idea, but "if it were my car"..., I would install Calvert monoleafs/Cal-Tracs and be done with it.
For inspiration, ActionAnge has more power and less tire and gets it done nicely with CalTracs.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/21/12 09:51 PM
From what I have read on moparts is the cal tracs didnt seem to make much diffence for alot of people on here with mid to high ten secound cars.

Are you saying one trip down the track for glory ET testing, or consistent 60ft results over 100's of trips down the track?
Sure, some folks can and do get it done really well with SS springs, but the complete Calvert package seems to be able to tame an inconsistent chassis.
CalTracs are generally more tuneable and are usually more consistent.
Posted By: dragram440
Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/21/12 10:05 PM
I would certainly be going with the caltracs over the ss springs. I just thought I read on here that most people with mid to high ten secound cars gained little or nothing going to the caltracs over the ss springs.

FWIW, I agree 100 percent. My pea shooter never hooked very well, never had much weight transfer, etc with ET radials, or slicks. The mild motor in my car right now was blowin the tires off really bad. Made some changes with the UCAs and strut rods and it dead hooks, it even actually transfers weight, etc.
At a local cruise night two weeks ago, a kid in a Cummins pulls up and starts talking trash. Mashed her down, never blipped a tire. Front end came up real fast. He said.."Oh.....Never mind..."
Until I made the changes in the front, it would have blown the tires smooth off.
I'll have a decent motor in the car in a month or so. I "think" with some minor tweaking it will hook fine..

I'd disagree with this from my experiences with them. A well sorted out SS spring is more difficult to improve upon. JMO, An 11.00- 123+mph car running 1.6x's in 60' is not a well sorted out car.
Ask Punk/Bryan Sloan about his deal with them. Car ran pretty consistent 1.45-1.47 on SS and ran 1.40-1.42's on cal tracks with ranchos. Car recently went 1.37 with afco's and runs 10.50-10.52 IIRC It was running 10.62-10.65ish on ss springs. Leaves nice, level and straight! As Bryan has said...
"I would say yes to the Caltracs and split monoleafs. They alone wont be the answer to any traction woes however. Its the total combination of carefully chosen parts."
The one car I dealt with that saw no improvement was because the owner didn't want to do what was necessary to make them work. The back was less messed up than the front.

I agree, my 60ft's didn't change going from Dvorak SS springs to Caltrac's. But what I did gain was some adjustablity for bad track prep. I 60ft in the mid 1.40's and run 10.40-10.50's

Randy, what kind of shocks do you have on it, both front and rear? Are your springs clamped real tight on the front segment and unclamped on the rear? Also, what converter are you running? Just thinking out loud. As for making more power with the new mods, I'm sure you will be pleased!
Randy

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/22/12 04:02 AM
The X' is slightly heavier than a no frills RR. So, front end rise IS important. The better the weight transfer is, the BETTER the "hook" off-the-line. I'm assuming you have the subframes connected, so the wisest things to do is make sure your SS or Caltrac springs are set with the rearend correctly shimmed for the proper pinion down angle. Front end also has to be set for maximum rise under acceleration, but not uncontrollable. The trick is to shift weight to where it's needed - over the rear wheels, under acceleration. And a pinion snubber can't hurt either, just makes traction even better.

Thanks guys!
I know the suspension isn't optimal by any stretch...but MUCH BETTER than it use to be!
For a 3,500 lb. street car,I think 1.52-1.56 short times are decent. Can they be better?..I'm sure they can!
I'm currently running Calvert 90/10's in the front..with NO sway bar. Out back are Rancho RS9000's and 002/003 SS springs..with NO additional clamping. The frame rails are tied,and I run a 4:56 gear...and Dynamic 9.5" converter,that flashes to 45-4600rpm. As far as chassis improvements..I'm open to ALL your ideas,and opinions!
I have thought about having one of my friends set up a ladder bar system..in the near future!
As far as the pinion angle is concerned,what would be OPTIMAL for a street driven..occasionally raced car like mine?...I believe Gary Jacob checked it,and it was 5* down. Thanks!

Wow Randy your car is set up pretty close to the way mine is.except i have the cheep summit 90/10 shocks on the front and some after market rear shocks for a dodge ramcharger.I am using 4.30 gears and some M/T 275/60/15 et drag radials. My best 60 FT has only been a 1.54 but most of the time i am in the upper 1.5 second range.I am guessing my 73 dart weighs around 3500 with me in it.I just put two Holley 750Dp on my car so i hope it runs faster next time out.But with the new engine mods and some tuning i think you can hit your goals and maybe more.

Bobby..I LOVE the Calvert front shocks!
HUGE improvement over the CE and Lakewood 90/10's that were on previously! I'm thinking the pinion angle could be improved,if increased to 7* down...from 5* down. But,I could be wrong! Need to find that out!
Take care,Brother! Thanks for your input!

Randy I run just SS springs with long C-body shocks in the rear and 90/10 shocks up front. Everything else is dead stock. My best 60 on the 30 x 9 Hoosiers is a 1.50 running 10.70's. If you get in the low 1.50's that not to bad. Good luck with it , Ron

I had the same setup as you and went 1.43 but in a lighter car. Your 60ft times look ok for a low 11 sec car, i would just put the motor in and tune from there.

The first time I brought my car to the track it would top the front shocks out then spin the tires. I put a set of longer shocks it and completely fixed my spin problem.

Randy - be serious... your car needs basic chassis tuning, not a friggin' ladder bar setup.
My Challenger runs 10.5s @ 3755#s w/ 1.45 60-fts on 275/60R15 ET Street Radials using CalTracs. They were worth .04 over a sorted out SS combination, plus added tuneability and consistency.

Like they said above you dont need ladder bars to make it hook up. My car is basically stock suspension and springs and it hooks up and runs 1.49 to 1.52 60'. I would make sure you have alot of up travel in your front shocks.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/22/12 03:29 PM
I'm sure it will dip into the 10's with the increased power. I bet the 60 ft times improve as well with the added compression and head flow.

According to the wallace calc, a 1.52 60ft is a 10.94, that says your car is where it should be.
As said by the previous poster, when your power increases your 60ft will drop at the same time.

Randy to help with your chassis works I have question when you painted your car did you fix your frame rails????

Hi,Gary!
Yes!..Steff replaced the section under the steering box...and reinforced it. Gary..would dropping the pinion angle from 5* to 7* help anything?
Thanks! I think down the road,I'm going to have you check EVERYTHING out and advise me on what can be done to optomize my set-up!

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/22/12 07:30 PM
Just last night I turned my pinion angle from 2 degrees up to 4 degrees down. We will see labor day weekend if it helps my 60' at all. So I have a hard time thinking yours isnt hooking up good because of the pinion angle. Im suprised mine hooked up with the nose pointing up like that. Like I say my chassis was basically set up very poorly and it still hooked up and ran a 1.49 60' so I would guess that you have another problem somewhere esle.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/22/12 07:59 PM
Randy pinion angle is a requirement to avoid u joint bind if a car picks up when the pinion angle was changed then it had bind. I dought if your car has bind with 7. We played with lens car for three years and only played with shock and front travel and picked up 4ten. to were we had an issue with to much wheel stand so there is alot to do with your stuff. what do you have for shocks? OOPS I GUESS I SHOULD HAVE READ AL THE REPLIES AND GET CAUGHT UP FIRST BEFORE I POSTED.HMMM CALL ME.

Randy I think ladder bars would be a bad move from the stand point of the purpose of your car. It is not a all out drag car. Would it pick up maybe alittle will caltarcs work, yes a little but for as often as you go to the track I dont think that would be in your best interst. I would be proud to own a pump gas motor that I drive to the ice cream store or berger joint that went into the tens and sixted into the 1.40's Your get what its got. Just tune it to its potentual and be happy. You will be just fine. You have nothing to be ashamed of. I built a car for my brother that he just wanted to go mid elevens with it so I put in a small Scoty Brown cam with ez heads on a 440 with one of those indy crossrams and 2 750 edelbrocks and put in way wrong converter for combo and the car on a good day will sixty 1.49 and go 10.30's at 131 mph. Talk about a turd out of the hole!!! Im imbarresed but he is happy he is going way faster than what he wanted. Maybe down the road we will change converters. Enough of me reambling but what I was trying to get to is when do we say enough is enough and live with or decisions and have fun. Your going to have a car that is going to give you allot of grins have fun just playing with its tune and see what gives a pay increase or decrease!!!

I only did the front. The back still needs alot of attention.

Randy, I agree with Gary. Work on optimizing what you have and you will be very happy. Some good chassis tuning and track tuning on the motor and you will have a sweet ride, especially with the new paint. But if you change your mind.....

Thanks everyone!
Like Steff stated..."the back frame needs some attention" He's referring to the rear of the car being weak...due to some frame-rail rot.
Unfortunately,I was on a tight deadline to get the car to the painter...or I would have had him repair it then.
It definately has to be addressed in the near-future!
Again...thanks for all your opinions,and information!

If the rear rails are not in the best shape and allowing flex, that will definitely eat up power that could be used for going forward. Get that thing gusseted up!
Clamp the front segments and loosen up the rears. May not help with the rails in rough shape...
Keep chipping away at it and set a goal in the low 1.40's.
Good luck with it.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/23/12 05:33 AM
Thanks,Rob! I plan on having Steff gusset the frame rails over the winter...or next Spring.

Re: HORSEPOWER NEEDED TO RUN 10.8-10.9'S ??? - 08/23/12 06:07 AM
Love the car, wish my GTX looked anywhere close to yours!
I'd also probably put more converter in it. That's just me!

Gusset it or use "box type" steel to replace the rear frame. Your traction woes will be drastically
reduced and the 60 ft times will go down. Once your car is "hooking" off the line well (and consistent) THEN start tuning for speed.

Steff's a real sharp guy!..he'll know exactly what should be done to fix my problem!
As far as converters go...more than a few people suggested I go to a looser 8" unit,but I don't know....I've had GREAT luck with my 9.5" Dynamic! But...I'm thinking,since everything's still apart,and not installed in the car yet..could be a possibility!..but only if I were to sell my Dynamic first!

Converter def. is a big part of your 60' I run a coan 8" with around 5000 flash speed. Suprisingly it drives on the street better then my last 9.5" 4000 converter I had in it. I love my coan .

I have a 8" Coan in mine also. Really surprised with it's street manners.
Drives like there's a 10" street vert in there but will flash to 5K on command

As BradH stated, work with what you presently have. Perfect the combo you have by tuning (both chassis and engine)and sound driving techniques meaning "knowing" what the car "likes" and "dislikes". Worry about the parts combo AFTER
you find out from tuning! Money can be "saved" through this approach for the ESSENSIAL parts UPGRADES! Don't FALL into the "Keeping up with the Joneses" approach. Hardly any good results through this method.

Brad..Ron,points well taken! I'm sure with the improved heads..and Steff re-doing the frame rails,I SHOULD be seeing some 10 second time slips! Now..just gotta put the X back together again!

FWIW (Steff may have this in mind already), outside of the frame rail repairs, reinforce the upper rear shock mounts and the area above the nose of the pinion housing, IF you are going to use a pinion snubber. It's to provide a solid contact surface for the snubber (distributes the weight transfer/engine torque shock to the chassis).

Thanks again,EVERYONE!
