Dragracing Viper Project (NHRA Super Stock Eliminator)

[jp]

For you who are interested in Drag Racing, maybe my team site will give some inspiration for future projects.
I'm building the first ever NHRA approved Super Stock Viper. The car and the engine are at the moment under construction in California. As soon as the work is finished will it be flown over to Sweden so that I can assemble it...and take it to the European Drag Race tracks.
Enjoy!

NHRA Super Stock rules states that I have to stay with a Stick gearbox, 3600 pounds, Stock Valve size, Stock CC:s on intake and exhaust runners, Stock Trottlebodys, Stock body panels (No Super/Turbochargers or Nitrous is allowed). So the goal is a low 9 with a 60 foot in the 1.28 range.

Very nice !!!

How fast do you expect it to be ?

Quite an endeavor, but it seems challenged from the start.


You're hoping for low 9's but the quickest n/a Vipers that haven't been stroked etc are in the mid 10s aren't they? It'd seem you're 1.5 sec away.



Except for Dr Fudge's 9.50s , but I'd imagine his engine's not SS legal either, nor perhaps his rear axle setup.



If no tuner in the US has taken a Viper anywhere near that quick with an engine like SS regs restrict you to, how are you going to pull that rabbit out of your hat?



Which SS class would the car be in? What's the class record for that class? I don't know SS procedure anymore.



Does the class record affect a car's chances on a given day depending how far off the class record that car is?

The fastest NA stroker is in the low 9:s.

I have the best Chassie builder, Phil Mandella. (Chassie it self will net more then people understand) We have one realy experienced Endurance Viper Engine builders, a very experienced head guy, that combined with that we do ONLY Dragracing will put us in the high 8 to low 9 sec bracket, don't worry.

I'm more worried about how to get the Vipers front end down to the track in second gear...

This bayby will race in SS/E The index is based on a 425Hp. Nobody has ever tried this before so there is no factoring or correction to the Hp. Index with Manual trans is 10.55. I would guess that the official record in E is about 9.35.

Quite an endeavor, but it seems challenged from the start.

Here is a picture that shows how the Cage is integrated with the frame structure. The block is just a mock up do decide how to cut the mid and front engine plates.

BWAAAAAAAHHHHAAAAAA!!! ROTFLMAO!!! 100lb Pulley, HAHAHA!!! That's f'n hilarious!

The intake manifold is going to be your best performance secret with your restrictions. What are you going to use?

Some people seem to be ignoring the fact that this is far from just a stock viper chassis with a built motor.

I see no reason why this car cant make 650-700hp and similar torque. And given that you should be capable of 1.2 60' times mid 9's should be easy. And even lower when you find out more speed secrets.

 

[jp]

Russ, as it looks now will we use a 10-tbo design but without 10 butterflyes. Run the 10-tbos up in to a plenum to wich we have the two stock tbos connected.
Stock tbos flow enough for about 1000Hp. The challenge was to get the stock valvesize and a stock CC intake runner to flow enough... You bet that intake runners in this set up does not look as a stock Viper head (but the cc is correct)
As you can se on the pictures, this is a Real Viper with a PRO-Chassie.
We will hit well above 650-700Hp.

 

[Russ M]

JP,

If its not top secret I would love to see your intake manifold design.

And I meant 650-700rwhp, about 800 at the crank.

 

[jp]

Russ, will se later on when we have tested the intake on the drag strip. If it works out as well as we hope, I'll post some pictures.
