A car that doesn't want to be seen.especially over the internet.
Really? It’s quite the accomplishment. Why push the stock parts so far if you don’t want anyone to know what you have done? I know of two guys who got close but have not heard of anyone else ever getting in the 8’s. We first did it in 2013 but were stuck at 9.0’s for a couple years. We really figured shit out over the last 4 years and ran 8.70’s-8.90’s every time out. That motor held up for 3 years, cylinder walls and all, and only came out to freshen it up.

My 18 year old son went 10.20 at 129 with untouched original heads in his daily driver. It then pushed the crank out the bottom, but that’s why we use better parts in the bottom end.

As far as power level vs ET, it takes a certain power level to run the numbers. We are all talking about turbo regals and mine still has the power options, cruise control, AC, 200-4r and 8.5 10 bolt rear, it not some gutted out race car or dragster.

PM me if you want or text or call me, I am very interested in hearing about someone else making this much power with stock heads, even if they only did it once. 402-813-0799

He didn't say he didn't want anyone to know what he had done. He said he didn't want to be seen on the internet. I'm gonna assume that's because he doesn't want people to know that the car he races on the street is an 8 second car.

No I will probably stroke it and do like you and run a narrow spread camshaft in a little bit bigger turbo than what I need to help bleed awesome bottom end
When we say narrow spread please clarify. Are we talking about lobe separation angle here? Forgive the peasants asking questions......

He's talking about valve overlap/the amount of time that the intake and exhaust valves are open at the same time.
