For those who believe they need a 30 x 14 x 3.5 inch intercooler they are obviously running 1700HP and need that size to match their system. Obviously. As for the majority of people....bigger is normally a compensation thing.If I recall correctly, Sheps IC is 24 x 14 x 3.5 inch. I've asked Shep to use my intercooler on his car before. Before he did this though he checked backpressure across his system which he found to be less than 1psi. I personally was surprised but if it would help him go faster I'm sure he would change the set up.Our Super Street kit measures 24 x 10 x 3.5 inch. I designed it this way for two reasons. One was for performance. Two for looks. Quit frankly it's larger than most people will ever need, especially those with anthing less than a 50 trim turbo. Check out GRNDSM (Reitman Racing) on this site under the 1/4 mile times page. He runs the VPE Super Street kit with my 2.5" O2 housing. Quarter mile time 10.3 sec. He's stated too that the car could probably go 9's with a few more passes on it. Point is, my real world testing has shown that you don't need as large an intercooler as one would think. For the record Curt Brown and Turbo Trix used our race core on thier cars and have run into the 9's. Turbo Trix stated on the dyno they made more power with our IC end tank design than anything else they've used. I could have sent them something larger but there was no point. Data logging statistics showed us this. AEM is a wonderful thing.One last thing to consider. Huge intercoolers will create slower spool times. There is more volume to fill. Bigger IC and a bigger turbo doesn't transfer to better 1/4 mile times because of the transient response. It's only a quarter mile and if its taking time to spool your not getting down the track as fast. Like some other people have stated, you don't just buy parts you build a turbo system.For those of you who "need proof". Measure two things on your own IC system. One, pressure in and pressure out to see if its causing excessive back pressure. Secondly, check the temps across the IC starting from the hot side and work your way across. I'll bet you find the IC is done cooling after the first 18 inches. The next 6 inches, assuming its 24 inches long, is just causing back pressure. Remember every car is different and your ability to tune plays a large roll in that.Keep in mind to purchase your kit from a reputable manufacturer. You may be paying a little more for the product but what your actually paying for is knowledge.Good luck.Scott R BelcastroVictory Performance Equipment
