Problems

Yes. I made a total of two prototype. The intent of the heatshield is to box off the JWT POP-Charger so that it is isolated from the heat of the exhaust manifold. The design of the heat shield is a single layer sheet metal that is fitted to go around the powersteering resevoir, and take advantage of the mounting bolts. On the front end, it is mounted to one of the two SR20DET Airbox mount point on the radiator top support. Initial design was too short. It left a 1" clearance between the top of the heatshield and the hood. It was discovered that, this gap ended up in a position, that all the hot air from the engine fan is directed towards. This in effect was a low pressure force induction. The problem with this was that, the environment in which my car is operated is Sunny Arizona, where it gets hot. After operation, the hood area above the JWT POP-Charger is noticebly hotter than other areas. Thus, the 2nd prototype. The 2nd prototype was redesigned to completely close off the 1" gap, thus effectively cut down the power output of the previous setup.

Tips

Be daring, play around with different configuration.

Thoughts

The 1st prototype/setup had a noticeable jump in performance. The engine would rev. to redline w/o problem. My first time operating the car with this setup, I bounced the engine off the rev limiter!!! Took my by suprise. The 2nd prototype, on the other hand was only a sliver better than a JWT POP-Charger setup without heatshield. Since this was only a prototype, it is not painted nor powercoated, but left in it's natural galvenized sheet metal look.

Other

I might go back to the 1st setup. Actually made some power.
