Spearco designed an intecooler for Renncpe's group buy, it's only available this week for $758 for a complete kit. After that it will be sold by Renntech for a higher price. You can reach him by phone at 800.434.8514 (ext 3306) or Email:
rstevens@brumosrenntech.com if you have questions or want to buy one. He did a dyno and got 15hp. It's tough to dyno an intercooler so I expect real life ponies to be even higher.
