As part of the build up of my car I'm gotten an upgraded intercooler setup made for it. The stock Toyota IC measures 2.5 x 11.5 x13. The actual core size is 2.5 x11.5 x 8. This unit is approximately the same size overall. The Spearco core is a little larger in both directions, and one inch deeper.
This is a picture of my air to air Spearco Intercooler which doesn't have the mounting tabs on it yet. As you can see, this is a quality unit. I've received the unit back and have installed it. My initial impressions are that it is making a large difference. My car has an J-Spec engine (8.9:1 compression), HKS intake, TRD Header, and Cusco sized pulley. Since I've had the new engine installed I've felt that it was a flat once it was warm. Don't get me wrong, it was still quick, but it really felt flat, especially as the weather here in Nashville has warmed up.
In some SOTP testing today (about 65 degrees, sunny and dry) it is quite a bit stronger, for a much longer time. I do have to say that it does induce a lot more intake noise. Sort of reminds me of when I first installed the HKS intake. Lots of new intake noise. The main thing is the car just seems more healthy now. I will be getting dyno runs done soon and will get some done with and without the new IC.
Last night (03/22/2000) I was down at Performance Garages here in Nashville. I thought I'd see just what my car was making and what the difference was between the stock and Spearco ICs.
The plan was drive down with the Spearco installed, run some baselines, switch to the Stock IC and then switch back to the
Spearco. The baseline results were less the I hoped for, but due to my car still running fairly lean and not having touched the timing they were acceptable. One thing we all noticed though was how smooth the line was. There was no sign of problems in the ignition system even though I have 30,000 miles on the current distributer cap (Thanks Marc Summers!)
