How-Too - Aerospike Mod

[dv/dt]

Here are the instructions for Aerospike mod to go with super porting the J-Pipe. Do it at you own risk and use all appropriate safety precautions !!

When used on conjunction with the J-Pipes Super Port mod they were good for 23 hp during our exhaust shoot out.

I started out by tack welding a piece of 1/16" welding rod to the center of the exhaust flange. You then want to bend the rod so that it goes straight up the center of the J-pipe. Make sure you double-check the orientation of the J-pipe to the sidepipe on the car as it isn't intuitive (for me anyway ). Some eyeballing is required since you can't see the rod inside the J-pipe when it's mounted. This gives you the right angle and gives you something to tape the patterns for the sides to when mocking it up. The rod is removed after the first side is tacked in place during final assembly. I then used some central vac tubing to make up patterns for the 4 sides of the spike. This tubing is nice since it is about the same wall thickness as the metal and is easy to cut with some aviation snips. Here are some pics of the mock up:
