Lee,

No - that was with the ported stock plenum and injector housings - currently on the car - exactly the way it was when it ran the 10.44 back in October. I surmise the dyno backs up the track performance. I'd think 580-585 would be possible with the Hogan from my prior experience, but I'd probably lose about 15 ft-lbs on the torque. I think that's a better match for a traditional 6-spd, but with my auto & the wide ratio gears, I think the tradeoff might be a push at the track. It probably would trap out a little higher with the Hogan, but I'm not sure the ET would change much.

I do expect to be at BG - knock on wood, nothing goes wrong!

think it would be easy to imprive the low end with the Hogans by modifying it alittle

if i can ask what is the total timing on the car,also what airfuel did you shoot for . graph looks good ,like there were no knock events .

Might be talking outta my arse but what about adding velocity stacks to increase runner length some...also improves flow, etc..

Nice Kevin.
Now those are some real numbers and backs it with ET/MPH.

Wow Kevin. That's the fastest 1/4 mile time I've ever heard of a street legal ZR-1 putting down. The only other one was Paul Smiths at 10.6. That must be an incredible thing to feel and experience. The cost involved in getting a ZR-1 to that level is also incredible.
