Hey brian. I finally got one I setup going to the track. Where are you with all your race math? This guy is chasing 1/4 mile times and I always valued your opinions and input on that stuff. Sound off, man.

We were Feeding LS ENGINES NITROMETHANE LACED FUEL in the Raceshop Chicago Wiz.

VP Q16 .
It has Nitro in it.
Make Krazy TORQUE & HP.

No one could stand the Fumes of the Twin 88 mm 6.0 LS Beast Running but me.
And the Head EFI Tuner.

We were taking VP Q16 Fuel fouled spark plugs.
Rub brisk against a wire brush.
Even in daylight It Explodes with a Bright white & orange flash of light.
Coolest thing to see.

The car is a C5 auto with the 4l60e and LS1. When the vortech supercharger went in I also swapped the diff from 2.73 to 3.42. I have a build thread for the car on this forum here:
http://www.digitalcorvettes.com/forums/showthread.php?t=283009
And also on the Superchargerforums here:
https://www.superchargerforums.com/threads/a-a-supercharged-c5-corvette.6045/
Looked at the Super Charger Thread.
Kinda neat.
Street Outlaws in Big in Florida now too.
All the action is on Facebook as you know too.

Different market clients.

Still full bore drag racing here.

I was building engines from a bare block.
LS INCLUDED.
Not many guys around here that can do it.

Have to watch those 4L60e's.
I just rebuilt a 4L60e for 1999 Chevy Tahoe 4x4.
Played hookey Monday from work.
Built it and got done Tuesday morning at 2 am.
Covered it on Grumpys site place.
Install this Sunday.

Turbo 400 still way stronger stock.

You know our roots are in restoration. This is a fun thing for us. We can not get this car out of the 11's. But the motor recently let go and we are swapping in the legendary b15 with a 10% overdrive crank pulley.

There are a few videos of this car going down the 1/4 mile track at Palm beach speedway. They are here:

https://www.facebook.com/kevin.scott.5667/videos/10213634434108735/

And here:

https://www.facebook.com/kevin.scott.5667/videos/10214104333295921/

on 20" rims with super low profile tires. Traction is a problem with this machine, lol.
Runs Strong.

Needs another set of Rear rims with Drag Radials.
If real brave Drag slicks.

Not much weight transfer on launch.

You did a Great job tuning.
Pulls hard and sounds Good.

Drag Racing is different from what your used to.
Chassis setup is important.
What works Road Race is not ideal for fast drag race launches.

Double adjustable shocks on all 4 corners would help.
VIKING COIL OVER SHOCKS POPULAR NOW.

DRIVER TECHNIQUE IS ALOT.
WITHOUT TIMESLIPS HARD TO JUDGE ACCURATE ALL.

The tires just spin. and the ass swings out to the right. I have been trying to use the electronic throttle body as launch control, only allowing to open so far vs. rpm. It needs more grip for sure. It is consistently worth 11.3 - 11.4.

500 flywheel Hp is enough to get a Steel Chevy or Pontiac Musclecar into 10's.
10.70 solid.
Takes 4.10- 4.30 -5.38 gears depending upon weight of car and torque band of engine.

A Corvette not chassis setup for Drag and Mid 3 series diff gears will take 650-700 hp.

4L60E is a bad trans for Drag Race even if it holds up.
Because so much time is lost on the 1-2 shift.
Ultra wide ratio gearspread.

A Turbo 400 or 4L80E will knock .50 -.70 ET off of 1/4 mile doing nothing else.
Provided you have the correct stall torque converter.
Not inexpensive for a Torque tube Corvette as you know.
4L80E is A Turbo 400 with Overdrive.
Both Close Ratio autos.

Superior to all.
Even what Dodge has.
Hellcats 8-speeds blow up its $11k to replace.
A Turbo 400 goes in instead.

That is actually comforting to hear. I have had many tuning sessions with this car. even invested in more books from the tuning school just for trans tuning to try to get the most out of this setup. I thought the power adder on a c5 should be worth the 10's. Guess I think too highly of these cars. :laughing:

Might go the 4l80e route down the road. Right now the car is running on a 2200 or 2500 stall converter with a jasper rebuilt 4l60e. Surely that will be the weak link in the chain and the next to fail after the b15 goes in.
