Needed for safe 500rwhp

05RedDevil · July 7th, 2008, 02:35 AM

I currently have 400rwhp/ 376lb-ft tq from the Saleen S/C with only the 4.00" pulley from Brenspeed and Borla c/b exhaust. I would like to up my power but I want to keep it well in the safe range. I hate the talk of reasonable power to risk ratio.
What has to be done to the motor and what all should be done to safely run 500 rwhp?
What is the most you could get out of the stock motor and keep it reliable as a DD?

450-465whp is where i would keep it on stock bottom end. to "safely" run 500whp you need to beef up the internals, what kind of fuel system do you have?

Talk to the guys @ JDM.

so an added question to the topic...what is the safest easiest way to get 500whp.. cost isnt really a problem just interested to find out the safest & easiest way then i'll get the money together

Power adder of your choice (s/c'er, turbo, nitrous)

Forged shortblock or forged rotating assembly.

And depending on which power adder you choose, you may have to add fuel system upgrades.

I forgot to ask if you have an inner cooler in that beast???

onederful100 · July 7th, 2008, 11:23 PM

for a DD i would keep it around 450 rwhp while keeping the stock internals. if it were not a DD you could push the hp and if something broke you would have something else to get you to work and get groceries and stuff while you fix the stang. but for a DD i would keep it safe and conservative.

+2 !!! They tuned my turbo setup. Jim Sr. made 515 rwhp, but detuned it to 488 rwhp for reliability. He said he felt comfortable at that amount for longevity. They are top notch...

Rampage · July 7th, 2008, 11:32 PM

so.....488 rwhp is safe for stock internals but 500 is not? just want to make it clear cause i really dont want to pull the engine apart to replace the internals

Like most will tell you... it's all in the tune. You will find various opinions on this topic to say the least. I've been running that much on mine for a little while now with no problems. I'll definately post up when mine lets go, but hopefully it will live for a while.

MaverickMLFD371 · July 8th, 2008, 07:54 AM

I'm running 470 with my whipple. safe conservative tune. get a whipple!

the newer generation 2 whipple blowers with the lightweight twin screw blade design is putting it at 500hp, safely! kinda wish I waited for a gen 2 whipple, rather than getting a gen 1.

the whipple is great for a DD
