Call Jason and tell him what you want and your worries. He'll be honest with you and let you know what he can do!
I am more than happy with my Heffner SC and will be sending my GTS back in a couple weeks for more!

whats on your car other than the Heffner SC to make the numbers you make? and what time did u run at the track?
My car was the prototype for Heffner's current supercharger package. As you can see from my signature it's a beast!
Jason Heffner produced the first 9-second supercharged Viper and my car held the record for about 6 months for the quickest supercharged-only Viper (10.20 ET). I plan to make some more mods in the future--this stuff is just so addictive!
By the way, Jason has at least one supercharged Viper out there with nitrous on it, but that car has never been tracked.

I run a small shot on my DLM car. No problems at all.

Who put the juice on your car, twin? Did Doug send you the kit and you got someone near you to install?
Thanks,

The basic package works with the stock longblock and goes plenty strong for most people... but if you want more then Heffner upgrades the engine to forged pistons etc to make sure the engine will live at higher power levels.
From there the possibilities are many - ranging from more boost to heads, cams, roller rockers, headers etc - whatever you need to get the result you want.
Beyond 750-800rwhp you will need to also spend money on upgrading driveline - at least half shafts, and depending upon your driving habits - maybe clutch.
Jason will walk you through your options and what they cost. If you want to run nitrous - tell him up front as you have a creampuff model.
