well ??:dontknow:HV SRT said:No.
Is Forged Pistons Enough?
- Thread starter SRT10VENOMOUS
- Start date
I would think forged piston on stock rods will be for 700 rwhp to 750 rwhp. I haven't read anyone of having problems with rods alone. Usually the piston would go first causing the rod to fail afterwards.

not neccessarliy, your stock rods are basically good for 650hp, 700 is actually pushing it

Is the stock rod limit RWHP or at the crank?
supposedly rwhp, but thats jsut what I have been told by the rod manufactures I have talked to

You obviously more about these engines than I do, and I don't mean to question you. Haven't all the engine failures stemmed from the pistons rather than the rods?
FlyingLow - I would figure the 650 would be rwhp. Because I've been at 620 rwhp for over a year now about 15k miles and I still running strong.

LOLOLOL no no no I DUNT
jsut relaying what I have been told, the stock pistons will go first, but the rods are a weak link also

I bow to your better knowledge kind Sir. Thank you for your input.

That is what I figured. I know my mileage will vary. But another topic would be what is the TRQ limit. i.e. 9 psi on the turbo that Marty did was at 647 RWHP and 733 TRQ. I'm shooting for a nice street able 600 RWHP and 700 TRQ.

You should be able to make that easy on 5 psi all day long, and that would be safe on stock internals. You should have no problems.

No way the STS can make 600 RWHP at 5 psi. I don't even think the Paxton's can make 600 with 5 psi.
I'm making 620 rwhp with the stock 6lbs pulley with a bunch of timing removed, catless mids, cat back, and everything else stock. I removed timing becuase not enough fuel with the current system to make the power safe.
Mickey is making 670+ rwhp with 60lbs injectors with the stock 6lbs pulley with just some shorties and a cat back everything else on his is stock including the cats
600 rwhp is achievable at 5 psi specially if you have the right fuel delivery system and Marty tuning it.

The STS make a lot more TRQ than HP. But I don't know enough about the other systems. Remember the STS does not come with an intercooler or meth. I still don't think a STS can make 600 RWHP at 5psi. I only made 478 RWHP with Sean Roe doing my tuning with a VEC3 at 5 psi.
What size injectors did you have? Had to be pulling alot of timing to get those numbers.
FlyingLow said:
WOW 478?? that's strange here are my 2 stock dynos one is fully stock the other is stock but with no air filter at all... just open tube... both runs same day.....
I think I'm at the limit of stock internals. I'm sure that the tune is keeping it together.
Here are 2 different dyno sheets from truck with different tunes and disconnecting the kick down cable for the dyno runs, both at 5 psi with the 4 extra injectors. I don't have a dyno sheet from the runs with my 60lb injectors. You can see that the TRQ is pretty high on the first one. Marty was only making 647 RWHP at 9 psi but his TRQ was 733. http://www.vtcoa.com/forums/showthread.php?t=24248

STS's advertised 550 RWHP at 5.5 psi with meth.

after looking at all these STS posts of dyno runs, I think one would be better off buyin a good used diesal and putting a tuner on it and jackingup the fuel.
the dyno graphs look the same as a cummings, well except for the trq falling below the amount of a stock SRT:dontknow:

The above dynos were really early on and with a basic tune. I was however very disappointed and the HP.
Here is a dyno of a stage 2 flash of my truck.

That dyno looks very weird. I would be interested in seen what your air/fuel looked like on that dyno.
