Is that with stock style (hyper) pistons? Boost level?

It is a stock 4.2 bottom end.

He is running about 10#'s of boost.

He has just raised the bar again. 462rwhp and 460rwt

Fresh Focus pump and some bucket mods to improve fuel pressure.
Some more tuning with A/F and spark.
A couple of gallons of 100 octane mixed with my pump gas as insurance.
And some intercooler in a white bottle compliments of Compu-Car. It was a 25 dry shot.

Just can't seem to break my "weak" stock shortblock.

Stock short block , ported heads & intakes mild cam little gas to cool.

I think he has more that can be tweaked out.

he's gettin' there! :D

i take it he got kicked out after that pass? i think he was the guy who refused to put a roll bar in right?
Kirk

Yes & he popped his engine at the top end of the track.

He is going to put another in. Needs more fuel delivery, the 300lph focus pump was not keeping up.

i was wondering when that engine was gonna breathe its last breath... regardless though, quite impressive. :thewave:

Well it was a combination of things.

He does not know if the NO2 fired, temps were rising and he was detotnating at the top of the track & drove it through the traps.

He got the time & will rebuild & be back. same setup.

he's not gonna put stronger internals in there while he's got it apart? i guess the stock stuff didn't hold up too badly, so i guess that wouldn't be the worst choice either.
Kirk

The stock parts did not fail. All he is considering is maybe different pistons.
