Re: 441 cid dyno results
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! Kevin |

Re: 441 cid dyno results
think it would be easy to imprive the low end with the Hogans by modifying it alittle

Re: 441 cid dyno results
Might be talking outta my arse but what about adding velocity stacks to increase runner length some...also improves flow, etc..

Re: 441 cid dyno results
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.
