Thanx for posting up!
Basically, its the same technique you would use on a RWD automatic. My best launch is holding the brake and holding rpms steady at 1300 - 1500 rpms and then on the last yellow release the brake and moderately roll the throttle on and then pedal to the metal (WOT) all within a split second. It takes practice to control the wheelspin and weight transfer. Plus the torque steer with the mods is minimal. I let the DHP PCM handle the shifting.

The GTP performs well considering its all bolt on mods. I'm at a dead end on better performance unless I go to an intercooler, roller rockers, cam, smaller SC pulley and race tranny. The stock 4T65E-HD tranny is not made to handle 12 sec. ETs.

Thanks for inquiring.

Re: Racers.... post your times

'68 Camaro, all steel body, 3,140 lbs. "dry"
412 CID small block (Dart Sportsman block), Eagle kit, Dart Pro-1s, Victor, AED 950HOM, Comp .660 roller
PowerGlide (TCI) 4,500 converter (made for nitrous, very "tight", TCI)
Chevy 12-bolt 4.56 gears
15x12x31 M/T slicks
All Deadenbear electronics

Horsepower (N/A) estimated at 710.

6.48/10.07 (110/131) on "motor"
5.71/8.96 (119/149.28) 300 "hit"

short times on motor in the 1.40 range, on bottle, 1.31 (best)
That's with a 240 lb. man driving!

The local crowd was so impressed, a man offered to buy the car (rolling). So, it's gone. But... Next week we begin the process on a '97 Corvette IHRA A/FC chassis. That small block will easily get the car in the 7s (1,800 lbs. "wet" with a small block). We have some blown/alcohol plans, too... 6s here we come! (and I DON'T mean 1/8 mile...)

We're also looking at a big block for match racing, and a Pontiac (surprise...) for the "Pontiac" races. And I don't mean Pontiac valve covers, either. A true "traditional" Pontiac V8. We'll have to do something about the Chevy body for that one...

How about a customer's car? They legal for this thread?

Rick Holladay, Virginia Beach
'65 GTO convertible
434 CID Pontiac, Edelbrock heads (9:1, 93 octane only), UltraDyne flat tappet hydraulic, TriPower (yes, really)
3,740 lbs. "dry" (weighed this past August at Norwalk)
Muncie "wide ratio" 4-speed, 3.73 12-bolt (Moser), ladder-bar suspension
M/T Streets, 15x9.5x26

11.95 @ 117

The car has no adders.

I know, there are plenty of faster cars out there. But this thing draws a crowd everywhere he races. He's won three bracket meets in North Carolina in the last two years (who says you can't bracket race a manual?)

Hey MrPbody.... that '68 sounds like a blast! 5's in the 660' and a 1.31 60' is just a wet dream for me at this stage of the game.... guess I could jet it up hard and not lift till I see the face of God .... but I doubt it would do it twice

Just curious about the NA vs. hosed numbers though....the 6.48 NA 660' vs. the 5.71 hosed 660'. Why did it take a 300 hit to get a 0.77 ET reduction? Is it b/c at that rate of power/ acceleration it takes that much more power at that RW to bring down the ET? Is it just me or is there somthing I'm missing? I know I'm seeing almost a full 1.0 sec. ET reduction(from 11.44 NA)and a 10 mph increase(from 124mph) w/a 1.44 60' on a 150 wet hit in my 3580# TA.... not calling you out on your numbers.... just curious

Your mph is DEFINATELY there though!

As far as the Vette goes..... 1800#'s at that 710 number oughta' be good for a 1.1x(if not a sub 1.0) 60', and I agree 7's should be a no brainer. THAT should be fun!

I'm still on the fence about the TA. Gotta lose weight. Seriously considering gutting it and doing a narrowed Dana/4 link and tubs. If I can get a 9.99 on this little motor I could move on.

Then there's the option of just pussin' out and buying a documented 8-9 sec roller and cutting the time line in half....

Thanx for postin' up! Good luck in the A/FC class.... that's some tight competition. Again.... just another of many wet dreams I have

Btw.... what shop are you affiliated with?

Re: Racers.... post your times

500,
Why do I know that name? It seems I've seen it before in the Pontiac family...

Low,
Yes, I think maybe you did miss something. The converter is designed for use WITH nitrous, so 60' and 1/8 mile times are slower "on motor" than they would be had the converter been "loose". The engine and car were initially "designed" for nitrous. By putting a "loose" converter in there, our "on motor" numbers would be more impressive, but ultimately, the car would bne slower by a bunch...

The F/C won't be going to the top to start with. We''ll probably put a T-bucket on it and call it an "altered" for the first year. That way, we can learn the chassis and still go fast, without the obligitory blower and exotic fuel. We'll use the small block from the Camaro for brackets. We're doing a big block for "match racing" (it WILL be alcohol-injected) and a 440 Pontiac for the various Pontiac-only races. We MIGHT even build a Ford, and use the car as a "rolling dyno".
Things are still up in the air a bit, as we only got the car Saturday. We shall see...

Jim

Nice passes! Gotta ask the obvious questions....

What's the stock gear in a Viper? With that kind of torque I'd love to see a 4.10-4.30(Dodge equivalent ratio)in it w/a sticky tire

Those passes were made on street tires? (Very nice 60' if so, and HOW'd ya DO that ).

Was/is that stock/factory weight for a Viper? (if not what's stock weight and what's been pulled?)

LOL!... a record is a record.... never too old! I remember the Belvedere's. Been goin' to tracks since I was 15 years old.... 45 now. Kinda' miss all the old war wagons of the 60's-70's. The Chargers/Cudas', the old Mach I's, 62' Chevy II's and the old battle ship 66' Chevelle's....

Seems like they were a dime a dozen then.... try to find one in good shape today is an excercise....

What were the average/typical RW/60' #'s

Are you still makin' passes?

Thanx for posting!
