Upper limits of the SRT-4

[Jared_80]

Does anyone know how much power you can squeeze out of a SRT without blowing the block?? I know that some of the jap 4 bangers like the 4g-63 have gone over 700hp on pump gas, but can the neon match that kind of power in street trim?

I have seen a few peeps go with a t3/t4 swap and run some more boost as well as a 150 fogger system on a srt, he is claiming around 500 whp... im not deffinate tho, and another guy i have actually seen his swap, he is saying at 15 psi it should put out 550 hp. but thats about as far as ive seen so far

i believe some guys run at bonevile a 600hp srt4 on a stock block

If i'm not mistaken, don't the NHRA Summit Racing series SRT-4 guys run the stock block? They're running, what, between 800-900 horsepower?

Yep! BUT, IIRC, the block is filled, as is usually the case with drag motors.

I'd be willing to bet that 700-800 hp is attainable with a stock block while keeping the coolant passages free. Who knows? At that level, much of the difference is in how well it was put together. Details are EVERYTHING.

I have heard rumors of a 1100hp SRT dragster, but those don't count because they don't have to run on street gas, and that is what I am interested in.

Well, yeah. Introduce alky to the mix, and all bets are off.
