SS Viper

[JP]

The stock injectors flow good up to about 600hp, so with a cam swap only that sounds like over doing it.
In general the VEC was a pain in the *** Piggy Back system, it's a Swedish system and our other Super Street Viper was a test Mule for it...did never work as expected.
There is a few systems out there that proclaim they work with the Viper, but most of them have errors, bad interfaces or have intermittent problem.
If I were you I would buy the new Infinity system from AEM when its available for the Gen2 Viper.
It's a $2-3K deal but it will help you.
Just find a experienced AEM turne with a Chassi Dyno, spend a half a day there and your Viper will Rock!

Btw, did you add headers when changing Cam Shaft?

Do you know of an ECM available that would replace the stock one? Most shops that claim they can supply one are very expensive with no assurances of success.

Thanks for responding.

The project continued and next step was to assemble suspension and brakes.
Our Viper doesn't have a regular 4-link, it wasn't room enough to make a 4-link the way Phil wanted it, so he decided to build a 3-link.


With a 3-link there are a few things that need to be 100% if you want it to behave perfect on the strip, one of them is the Anti-Roll Bar. When we received the chassi we decided to build a new Anti-Roll Bar. One that is far more rigid compared to the first one we had.
First a CAD Drawing

The final product, more of a Aussi Pro Mod style.


After that the focus went to the front end stuff. The stock hub/spindles (6-lug) was replaced with Dodge Dakota spindles and the Brakes came from Lamb. The Front Coil Overs are American Eagle (what I had on the shelf), They been shortened and revalved...but will probably be changed to a set of Ohlins in the future.


The Master Cylinder from Lamb on the narrow footwell.


After everything was in place we found out we had a severe Bump Steer problem. We tried different solutions but ended up with moving the Steering Rack and fabrication of longer steer rods, so now it's acceptable. Any way the car isn't built for huge wheel stands.

Looks like I'm not allowed to upload more pics, so the build story stops here.
Btw, 2nd test pass we did 9.39/147...
:-)

JP, congrats on making it this far with the combo, I've been trying to keep an eye on it when I can on facebook. Given the power you are currently making with the engine, what do you think your low ET will be once you get that power to the ground. Also, is the engine make better than competitive power and do you believe their is more untapped potential in the combo?

thanks for posting on here, not all of us are on, or look at facebook.
amazing project. keep up the good work

Hard to tell, but a 1.00 under doesn't look like a big challenge. But we want more than that out of it.
The Gen 2 heads have some week spots so we can propably not find more there, can't do more with the camshaft without being to bold for the Valve train. The intake manifold can probably be improved, we haven't even started to lean the engine yet, it's just a base tuned right now. So when other issues are sorted we can probably find some more in the tune. But besides that we probably need to work with the intake manifold to find more power. But we will leave the intake experiment for season 2016.

We will not race more this season, have already gathered enough info, no use to continue with what we now have, upgrades are needed.
New gear box gearing 1-4th gear, new rear end gearing, put in a alternator and a few more minor things. Besides that a engine ovehaul, we been running it on over time...

Its been a long project, but I must admit the result is very rewarding :-)

It's a shame I can't post more pics, looks like I reached some kind of limit for my account...I guess only admin can tell.

Well, I'm glad you guys were bold enough to take this project on, I've always wondered what this engine can do and your allowing us to see that. Would be cool to see it summer 2016 and if you can find a way to stiffen up the valvetrain even more without being too heavy, there will be even more HP in the combo. Fitting in more engine cycles with RPM usually means more power with engine changes to accommodate it.

Btw, a nice write up in Dragzine a few weeks ago:
