INTERCOOLER

[99SIVTEC]

Well a turbo puts out very high temps when not intercooled. I saw a guy that measured his temps. He averaged 361 degrees non intercooled and 160 with an air/water IC. Big drop in temps. The JRSC at 11 psi is somewhere around 190 degrees so its actually more efficient in that sense. I'm not sure what the HP increase would be at 6 psi, but probably not too much. Where this will really shine is above 10 psi. I'm talking with another board member here and it looks like he might have some good input. It might be possible to fit a spearco intercooler core inside of a special manifold. Keep your fingers crossed...

Turbos aren't sapping power off the crank so they still should have more peak HP.

Boost. Finally.

They will still ahve more peak, but the gap will be much closer than it is now. Besides that the supercharged car should be able to get so far ahead of the turbo car off the start that the small peak hp difference wont matter much. As for the performance gains well here are some rough numbers. Take these for what they are. At 10 psi it is typical for the blower outlet temp tp be around 190 degrees peak. Most intercoolers are around 60 to 80 percent efficient. Lets use 50 percent. That drops the outlet temp by nearly 100 degrees. now its a common guideline that you gain 3 percent in power for every 10 degree drop in temp. This equates to 30 percent more power. SO if your engine made 200 hp at the wheels it would now make closer to 260 hp. Nice gain. This doesn't take into account the pressure drop that occurs from the IC, so plan on a 30 to 40 hp increase. I'll work on some more solid numbers, but that gives you the basic idea. It should help peak HP numbers by quite a bit if I can get this core big enough to keep up with the blower.

Just curious. . . how much would an intercooled JRSC GSR put on (estimated hp) for 6psi? I know that this intercoolor idea wouldn't be as efficient as a turbo intercooler, so we probably aren't looking at the 270 hp figures that the Drag III's have. . . but any increase would be nice. <HR></BLOCKQUOTE>

You wouldn't really see big gains at 6psi. Big gains would come at 10psi, and more at 12 if you think the blower can handle it. I'm not sure exactly how big they'd be.

This can give you some idea of the outlet temps for the M62. The scales on the Delta T, or change in themperature are (I think) 80, 130, 180, 230 and 280. As you can see, at high rpms and 10psi, with a 90 degree ambient temperature, outlet temps hit 270 degrees F. Cut that down and you've got some big gains.

Its worth mentioning that for you drag racers, a properly set up air/water intercooler system can use an ice water reservoir, that can actually bring boosted air temps to below ambient. Its hard to get a large enough space for a reservoir in the Integra (the car I was looking at to do this in), but it can be done.

Imagine that: on a 90 F day, going from 270 degree intake temps at 8000 engine rpm and 10psi all the way down to <90 F. WOW.
