Re: 900 HP on pump GAS ,NA
Thats what I am thinking here......
Bob, myself, Ron, and sheetmetal Dave (damn close with only a 383ci) right off top of my head. Have run 9's with a bolt together engine. No magic parts.
All in 3600# + cars.
I think running mid 9's is a much easier goal than making 900hp.
I wouldn't be too concerned about building something to achieve 900hp as I would about building something with a power curve to propel a heavyweight street car.
With enuf cubic inches I don't see it being too hard.
Our little 496/505's are within .4. Would mine be quicker with radial slicks and a real good converter....I bet. Maybe a 9.8 or 9.7x????
Add some inches eg. 565/582, some more head, bump comp from 10.5 to 11-11.5:1. I see no reason mid 9's are not possible on pump gas.
I agree, I don't think 900HP is needed if the car works. A decent 750~800HP 540~565 10.5~11:1, 335 AFR's, and a .680~.714'' lift would be street driveable mid 9's in avg track conditions, and still pull high 9's in 3~4000' DA.
900HP NA on 91 octaine might get kind of wild with 750''+ lift, and gut ripping valvesprings that would require frequent maitenance, and likely give you problems on the street.
