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?

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.

That makes no sense...no one posts more pictures here than I do lol.
Try a Photobucket account (free to a point) or another image hosting site.

Ok, I give up :-)
Will use my Flickr account instead.

Ok, lets try to continue the build story.
As I've been runinng a Viper business for many years (not now though) we had many choices picking headers. We dynoed with 4 different sets, didn't see much difference.
Ended up with a set of American Racing Headers. Nice work, perfect fit. Probably not the best performing set, but good enough for us.

The exhaust routing and frame on a Viper makes it impossible to exit headers under the car, this is the only way to do it.

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 :-)

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:
