That's nothing, my TJ can run 6's in the quarter, the only problem is it's super expensive and time consuming arranging a C-130 to get it up to drop altitude :-p
12 seconds is a decent time and nothing to scoff at for a daily driver on pump gas!
I remember having a driveshaft attempt to come up through the backseat of the Camaro once. I have loops now.
You must have seen the old BBS Top Gear where they did a 1 mile drag race with a 911 Turbo vs a Beetle.
Looks like it needs injectors, but otherwise pretty complete and would be a great deal at that price vs what they cost new.
I knew Avenger. They were based in Colorado Springs when I lived there. In fact that was the one that opened my eyes to how the supercharger could improve the TJ. There was a couple at the first or second ROF Moab meet up with one and they mentioned how it improved their highway fuel economy while adding ~100 HP and just making the auto much better to drive. The NV3550 has always been a pain on the highway because 5th is a bit too tall and 4th is too low and has a harmonic resonance at highway speed. Yeah, I'd be down with that I thought at the time. But then I thought, I don't really want to spend $5,000 on it.
Unfortunately, they're out of business, I have a '04 and it would require a reflash of the PCM and they're not around to flash it. Of course I could get a tuner to do it, or buy a tune for a similar SC, but I'm not convinced the bought tune option wouldn't be a basket case and getting a custom tune would probably eat up any savings. I'm just not sure about sinking money into a SC with no vendor to support it.
It seems like the RIPP and Magnum Powers layout have some advantages in terms of space for the intercooler and retaining easier access to the engine vs those like Sprintex and Boosted Tech which are stacked right on top of the intake (especially without an intercooler).
