Ok , im starting to look at running a glide behind my 500 inch motor to try and kill it some off the line running TT5's and not completely relie on a 7531 box

the biggest problem i see is i need to weigh in @ 3425 to make weight

i know it will kill it on the shift recovery

looking for any of you guys that switch to a glide @ similar weight to share your results.

thanks Bob

We run a glide with 3.89 gears on our TT5 car. We used to have a 493" motor in the car and didn't have any problems at all with it. You'll just need a loose converter if you're trying to run N/A. We run a really tight converter because of nitrous but our setup seems to work really great.

i will be running 5.38's in the rear
and looking at a 8,000 to 8,500 convertor

with all the talks ive had with Chris (B1CUDA) his is a caged beast with a 400 in it which is what i was planning to run.

The glide won't hurt it, probably the opposite in fact. You have plenty of torque, use that and the taller low tranny gear, to make wheel speed. Wheel speed, not engine rpm is what gets you down the track fast.

Monte

Bob, I run a glide as well and my car is close to that in weight. I run a 1.98 first gear and a 4.10 rear gear. Car runs 6.60's on drag radials N/A with a pump gas stroker smallblock. Runs low 1.4 60's on motor and runs 5.80's on nitrous with low 1.3 60's. I think you will actually go faster with the glide as long as the converter is right.

Btw....Monte can sell you a nice glide, we got one from him in our car.

thanks for the info
my Hemi 99 isnt done yet so im not real sure where HP and TQ will fall.
it will be at Pro Stock specs. and now my matching sheet metal intake is legal other than i can run only one carb on this deal.

i was checking out the new Big Bo's
any one you know Monty running one of these ?

Why not just run a higher rear gear to tame the launch? This will leave more gearing at the top end to boot.

Because, if you knock enough gear out, to really calm the car on launch, once you stick it in high and everything goes 1to1, you don't have enough rear gear to accelerate the car. It takes serious power, to drag a heavy car in high gear, with no rear ratio.

A 99 Hemi is a screamer not a grunter.

I have been trying a glide with my screamer with bad results. You run a high stall converter and the engine just lays on the stall too long due to the gear ratio. 1.96X5.57=10.92 not enough gear ration on launch with a 7,800 stall. 1.96X6.17=12.09 the car will attempt to leave and not lay on the converter but still has trouble when going in to high 12.09 back to 6.17 and lays on the converter too long again. This is the delima with the 1.96 first. Ran the 1.76 with a 4.88=8.59 with a 7,800 converter it still laid on the converter too long. Run a 7,100 stall and it would not hit as hard but would come off stall quicker and with a little tire would get wheel speed and do decent. Seems the lesser stall worked well with lesser tire and get some wheel speed. Turning the engine upstairs you make a gear change that could get you off stall quicker and accelerate the car. The high stall would just laber too much on the stall speed and the car goes no where. I've tried every gear from 4.88 to 6.17 and several varieties from PTC and also Lenny at Ultimates best guess. The fastest combo was an accident 1.76 first gear with a 4.88 rear and a 6,500 PTC 8" converter. The car grunted when it left and had to have some timing pulled in a few spots on launch but had a better 60 ft and did not lay on the stall speed anywhere but ran faster. Would like to try this with more rear gear as the engine can handle the gear ratio. It just seems the screamer style engines prove time and time again in comp to like more gears in the tranny. This way you can run a high stall converter and a lot of gear but never lay on the converter as it will quickly pick up due to gear ratio.

A 500" 99 hemi is nothing in comparison with a stroked wedge design. These engines make huge power but have tiny strokes. Look at a RPM graph off the data recorder on a Pro stock they never see anything below 8,500. You run a glide with a 28" tire and you are problably looking at a 5.38 gear. With that gear you will be 2.5 seconds into the run before the driveshaft sees the engine RPMX1.80(trans ratio). Then it will do it again after the gear change for about .8 seconds. I have talked to several people with engines of this type who switched from glides to Pro flites or sticks and the results were huge.

Beleive me I would love to figure this out and save a lot of money and headache. But, many people who have done this game successfully say it is just not an easy target to hit. Change over and you can't miss. Seems people running the Pro flites can survive with a high first gear, low 2.-'s in light cars but can't give up the extra ratios in the gear changes. 3,400 lbs is a lot to move with a 8,600 converter if the car does not pull ahead of that RPM pretty quick.

What kind of torque will the 99 hemi make at say 8,300 RPM. I know of one that would not run 5.0's in a 2300 car with a glide. Don't know the exact setup.

just saying hmmm....

Leon

how much for a glide for a sb,i've been lookin and they vary big time?

not sure on TQ, im thinking 700 to 800 for those numbers.
maybe Chris will chime in with some numbers from his motor.

the key will be the convertor, i wish Marv was still at A-1

Hmm, could prove challenging keeping a engine made to run at 10,000 rpms with a 3.6x stroke in it's powerband with a glide in a heavy car. Shift recovery with a 2 speed and a high winder like this could really be a problem. I agree with Leon that in a high rpm, short stroke n/a engine in a heavy car the glide isn't the right choice.

The engine should make 750-800 ft lbs of torque max. Pettywitt's Chevelle has made the fastest a/m lap at Milan and it's a 632" beast that makes way more torque and it gets down the track most times with a t-400 trans. The car that won the class the last two years was a 655" engine with a 3 speed. If they can get down the track then I see no reason why your Hemi 99 couldn't.

Either way I wish the best for you Bob and can't wait to see it go.

Bob, In a nutshell, you need to do the exact opposite of your first sentence in your post. To get the full potential out of one of these Hemi's, at this weight, you absolutely have to rely on the 7531, and find the sweet spot, as far as building instant wheel speed, and managing a constant graph going downtrack, with the most minimal slippage on your gear change. In the N/A world, the 3rd gear is almost considered a "Power adder" as you are going downtrack. I have a Rossler TH210 with all of the lightest internals that Rossler currently offers, and I couldn't be happier. My 8" ATI converter flashes at 8500, and my shift points are set at 9400 (which is an insane feeling when you are skating around on a true 10.5 tire)
My current rear gear is a 5.38, and the converter, according to the Racepak, is only slipping 4%, so, it is in the ballpark.

Here is the info off of the last pass that I made with the car in June, in 5500 feet of air. Outside temp was 96 degrees, Track temp was 122 degrees, in Vegas. (This was only the 3rd pass ever, on this combo)

60 foot: 1.300
1/8th mile: 5.33
1/4 mile: 8.56
MPH: 158.96

Although this doesn't look impressive, I was pumped due to the following reasons.....

We took 15 degrees of timing out for 1.5 seconds, and it still went 1.30 flat 60 foot.

The car literally spins ALLLLL the way through 1st, 2nd & 3rd gear, I mean to the point of hazing the tire all the way down the track. On this pass, I pedaled it twice, as I thought I was going to stuff it into the wall, and the Racepak showed that I was out of the throttle for a total of .38 seconds.

I gathered the car just passed the 1/8th mile cone, and laid into it until the 1000 foot cone, where it got very loose again. I let out completely and pulled the chute. Game over.

This car is nowhere, and I mean NOWHERE near it's potential, as we clearly know that we have the car set-up as a POOCH at the hit, and we have only set the shift light to 9400 on the 1-2 & 2-3 one time. (On the pass above)
We have our work cut out for us, in finding that sweet spot, but, I couldn't imagine trying to work with this motor, using a glide. As far as the torque comment, I only know this by the motors that I have owned, but, my old B1-MC motor that now belongs to Al Alguire, made way more torque than this Hemi, which I see as a huge benefit, on this little tire. The problem, however, is the add'l. 350+ HP that this Hemi makes, over my old B1-MC.

I do not know, as I have no knowledge of anyone else in the country with a car set up like mine, but, I would be willing to give the glide a try, if my car weighed 2600-2800 lbs, but, that is not the case. I feel like the 3 speed is a must at this weight.

Here are, what I believe, have been my most valuable assets so far, with this motor...

The 7531 - (Can't wait to give it all of the timing much quicker)

Racepak V-300SD - Hands down IN-Valuable!

I am sure that when all is said and done, before this car meets it's potential, I will probably go through a few converters, and a few gear changes, but, there is no way that I will get rid of the 3 speed. I never, in a million years, thought that this motor would be as "Finnicky" as it is. I was told by Bob Panella that these Pro Stockers are like a high maintenance woman, and it is sooooooo true. (But, still worth it, as it is the most bad-a$$ Mopar engine on the planet)

Happy Thanksgiving!

thanks for good info Chris
if i where smart i would set it up for OLS with no weight limit but i want to try and get a Mopar back in the A/M feild to give the GM guys a run for there money

next year im sure we will see some 8.0's and possibley a few 7.90's out of a few heavy hitters in the class in good air, Alen went a 8.13

i know i dont want to do this twice

Bob I am sure you will find that the MSD and Racepak will be your best friend LOL. Mike and myself have relied heavily on both. I still have the 7530 box in the car. In your case the power will not be the problem, but being able to manage it on the small tires. We run a 3.07 first in the Liberty and a 4.10 rear gear with 28x10.5 tires.
