Intercooler Gains?
I am starting the install of my intercooler on sunday. It is an ebay intercooler bar&plate with 24x12x3 sized core. I also have BTI piping. Called my tuner a little while ago to ask if it would be safe to run 10psi and he said "dont do it", so im not going to. Im keeping it at 8psi. He also said that I wouldnt even need to change the pulley on it because I will only lose like 1 pound of boost at most. It hits 10psi on occasion anyways with the powerpipe. But then I told him I wanted at least 380whp and he said that would be very unlikely. He said I may only gain 15-20whp with the addition of an intercooler[:@].
My car put down 350whp before and so now im just looking at maybe 370whp intercooled. Kind of dissapointing, I was looking for 400. Does this sound right? Only 20hp? He said they would have to add fuel and increase timing by 2-3 degrees. How am I ever to make 400? Do I need a cam? I am still on stock throttle body so could I gain alot with a 70mm? I want more than 20whp.....
oh yea and this is on a mustang dyno....

RE: Intercooler Gains?
feel free to run 10psi, the tuner should know to tune it conservatively. sounds like hes afraid youll split the motor at the 400rwhp mark. i ran 10psi on my stock block for a long time.

RE: Intercooler Gains?
The entire objective of the intercooler is to enable the engine to take in cooler more dense air charge -- up to 110 degrees. With that advantage, you can safely raise boost levels up to 3 psi with inpunity. Naturally you have to reflash and you tuner has to be on the ball as your engine will be running more lean.
If you simply add an intercooler without replacing the pulley with one of a smaller size, all you are going to do is lost a pound of boost and about 13 rwhp.
Looking back, I made 363 rwhp with a 3.60 pulley --non intercooled. I went with an aftercooler and a 3.125 pulley. My tuner made all the right air/fuel changes and the dyno hit 422 rwhp -- 49 rwhp gain and 3 psi. The better tune helped. At the time I was running stock internals, so my Tuner "detuned" it down to 409 rwhp to be safe.
A stock bottom can go 409 rwhp safely providing the guy tuning the Mustang is confident in his abilities.
Find youself a better tuner.

RE: Intercooler Gains?
hp gain will all be in the tune.
with an intercooler the tuner can add in a lot more timing
and more boost, for more hp.
Its not boost that causes detonation. Its the heat made from compressing the air.
Intercoolers take that heat out and allow for more boost on same tune or
more aggressive tune.
You should be able to run more boost if you want, but update the tune with it.

RE: Intercooler Gains?
take the time to find a good tuner. trust me. i just took my car to the local speed s shop and he blew it up. got it home and there was a big chunk missing out of the ring land.take ur time, do research and find the right tuner, even if u have to travel quite a ways. i was only running 10 psi. when it blew and he didnt' even tell me about it, i'm thinking about a lawsuit......
