New best....in the 8s!

Ran a new best at Darlington last night. Finally got my 8 sec pass! Went out there to do a little testing for an upcoming street car shootout. I had taken the 275 pro radials off a couple weeks ago and put a new set of 295-65 radials back on it...same size I used to run. Never liked the looks of the 275s on my car, never ran any better on them than it did w/ the 295s, and I couldn't run the 1/4 on the shorter tires.

Track was hooking great for everyone but me to begin with. First pass it just lit the tires up, so I came back and made some adjustments on the shocks and left the new 295-65 M/T drag radials at 18.5 psi.

The next pass it pulled the front wheels about 1 foot up in the air and then the nitrous came in...gained another foot or so of air under the front tires and carried it for about 100'. Got a little squirrelly when it came down, but I stayed in it b/c I knew it was on a good run.

60'...1.311
1/8...5.710 at 121.57 mph
1/4...8.955 at 149.70 mph

Not sure what tripped the 60' beam, but it wasn't the front tires.
That was just my 2nd pass, but it was late and I was happy , so we loaded up and came home.
I have just now gotten a handle on the traction and haven't even started tuning on the nitrous yet. I think there's some 8.80s in it easily. Want to thank Stephen Daurity and Monte Smith for the advice.
Not bad for a 3900# street driven car.

Congrats... thats the same tire I have on the
Rampage... what is the weight on the rear of the car
so I can get a idea of the pressure I will be running..
how much spray were you running

Congrats man............. Weren`t you running mid 9`s n/a?

Thanks yall!
Mr. P...not sure on the weight percentage. I have it in a file at home from when I scaled the car years ago. I'll look and see and get back to you. I ran 18.5 psi kind of as a baseline last night. The fastest I've been on motor was w/ 20.5 psi in these tires. Just wanted to be sure it would hook last night, that's why I ran them lower.
Spraying about 250 hp.

Thump...thanks and yes, the car runs 9.50s-9.60s at 140 mph on just the motor.

NICE..............

Very stout!

Congrats!

60'...1.311
1/8...5.710 at 121.57 mph
1/4...8.955 at 149.70 mph



How can you not LOVE that. GREAT run!!!!!!!!!!

congrats! Always loved that car!

Awesome, buddy!!

I thought about going, I knew the air would be great!

Nice pass!

Awesome! Gotta love a full weight street car that runs 8s.

Nice Job Chip!

That's awesome!

Congrats! Always loved your car. A 8 second pass isn't as easy to accomplish as everyone thinks!

Nice name change!

Congrwtulations!

Nice pass Chip and congrats!!

Congrats Chip!

One of my all time favorite cars just got better! Congrats Chip!

This is great. Congrats.
That E-platform is really moving the earth.
You do know that you're in another time zone now that you're 8 seconds ahead of the current time.

excellent!!

you're too fast........

Very nice to see you get it in the 8's . I'm still chasing them.
Doug

Congrats on the pass.

Congrats and don't give up on the 275 pros as they're a badazz tire...we've been 1.140 sixty on them @ 3200# !!

Congrats, Chip. I'll be joining you soon.

Congrats chip! I remember when I first came on here your screen name was "an11secondcuda". That says a lot.

Congrats Chip, nice run!

VERY NICE !

Well done sir.

Congrats!!!!

Congratulations Chip!

Is this drivetrain setup for the spray?(compression/cam/converter).If I remember correctly this is a Big cubic inch pump gas motor correct? I'm planning to make an nos past tonight for the first time on e-85.

Thanks yall, I really appreciate it! It was a long hard road. Making the power was the easy part, getting it down the track took a lil while, lol. I've learned a lot during this time though.

RacerX...I built the motor back in 2006 w/ the intention of spraying it all along, but it is not really a nitrous motor per say. The cam works OK for nitrous, but isn't a dedicated nitrous grind. I did have another converter built for the nitrous so I could keep my good "motor" converter on the shelf in case I ever decided I needed it. I hated to mess w/ it b/c it works awesome N/A. The pistons were spec'd w/ nitrous in mind (lowered ring lands, thick pins).
Yes, it is a big inch pump gas motor (around 11:1), but I'm not spraying it on pump gas. Heard way too many horror stories about running pump gas w/ large amounts of spray (even though 250 isn't really that much), so I decided to play it safe and run race gas.

This run was w/ a "baseline" nitrous tuneup that's most likely undertimed and a little fat. I also had .3 sec delay in the digiset, so it'll definitely go faster if I decide to get after it.

Robbins...the 275 pros work good (almost put it on the bumper w/ them a few months ago), they just looked like donuts on my car. They got lost in the wheelwell. Guess I'm just used to the way the bigger 295-65 looks on it. I was out of gear at 1000' w/ the 275s, so I decided to go back to the bigger tire.

Well done Chip!!

According to the Wallace calculators, my converter slippage was only 6.8%. Kinda surprised by that.
149.7 mph, 7400 rpm, 4.10 gear, 94" tire circumference.

Awww man... now I gotta put a bottle on The MoPig so I can change my name to a9sec73chally.

When I first came to Moparts, my screen name was an11sec70cuda and has changed 3 times over the years. My screen name is BigHemi on every other board. I was gonna change it to BigHemi here, but figured a lot of people wouldn't know who I was, lol.

Congrads! I see you already updated your handle

Congratulations!

When I grow up I wanna be just like Chip. Glad you are getting it figured out, thanks for the shout out.

Way to go Chip. Your knocking on parachute territory, LOL.

Awesome Chip!

Top stuff Chip - I too noticed the name change lol

You're really moving now - LOVE that Cuda of yours.

Awesome stuff!

Again, thanks yall!


Mr P...The last time I scaled it (2006) the car was lighter than it is now. Total was 3463 lbs. without me in it and NO fuel.
The weights were...
1764 lbs. on the rear 46.8%
2005 lbs. front 53.2%
