[Saleen S281]

Yeah I just cant decide where I want to keep it at! I dont want to put the 8.7 in and then it blow up lol

Plus I dont trust myself with a boost controller! haha

Lol

I ran 8.7 and it was fine bro. You'll be fine, just make sure Lito keeps the tune healthy and conservative. Which he will

Ok man that sounds good. Thanks!

Couldn't help it, and my wife is all up for it but we are now looking into internals or a short block to turn up the boost. I heard from many people turbo power is addicting but damn, lol. I haven't even turned it up to 9psi but I'm ready for more. I'll be doing alot of searching to see which is the best route for me, I'm open to doing a 302 stroker and doing the engine work myself except machining, etc. since my engine has 80k miles. Time to use the crap out of the "search" function, lol. Maybe I can take JR Granatelli's offer and see if what we can come up with, who knows.

Sorry for the noob question but, what does "dumped downpipes" mean? Just read throgh the whole thread, looks great!

Basically no muffler. The down pipe is what comes off the turbo towards the rear of the car to connect to the factory exhaust. Dumped down pipe would mean the exhaust would end before it splits off and goes to the over the axle pipes and axle backs.

 

[warpig12354]

So there would be no point in an axleback? Only for show? Thanks for the help, great build btw, just read through yours as well lol

Dump pipe - they are referring to the turbo by-pass. The turbo has a waste gate. The waste gate "dumps" exhaust pressure when the desired manifold boost is met. (Short answer) In many applications the "dump" pipe goes back into the exhaust and it is quieter. In the case of the Granatelli S197 kit when let the dump pipe “dump” to open air so when it goes into by-pass you can really hear it. If that is not clear enough I will try to go into more detail – just let me know

Thats good, thanks!

Above - Here are "dump" pipes that go to open air

Below - is a picture of what comes on the S197 kit

Below you will see when the dump pipes go back into the exh system

Clearer now?

It does make a lot more sense, thanks.

So according to that chart, I won't even make 400whp at 8psi?

On the chart it made 441 at 3700 rpm.

 

[retfr8flyr]

On the chart it made 441 at 3700 rpm.

No at 8psi it made 397 hp at 5300 rpm and 441# torque at 3700 rpm.

That's what i thought, but its torque figures.

Oh shit lol, well I guess that would be very early in the rpm to make that much power! But hearing and seeing what everyone else has made with around that much boost I'd say mid 400s are easily obtainable.

Now that I think about it, I think this is on a bone stock car with the stock injectors with 91oct fuel. I have a Magnaflow/Saleen exhaust, cmdp, 39#injectors, 93 oct, Saleen udp, and Lito tuning it, so I'm guessing I'm at least @ 430whp @6#s. I'll know more when I go to the track.

Did your saleen come with forged internals?
