Heat wrapping crossover gained 3 psi
Just thought it was interesting that after wrapping my crossover with header wrap I gained abou 2.5-3 psi of boost with no other changes. I did not touch the wastegate after wrapping just to see what it did.
Boost went from about 8 to 11 psi.

I am 99% sure I had no leaks, however I may have had a slight one that I could not pick up on. I think it is mainly due to my crossover being 18 gauge wall mild steel. Loses at lot of heat.
The crossover connect my passenger side stock manifold to the drives side log header. Length of the crossover is about 3.5 feet give or take a couple inches.

My opinion is wrapping would be more effective than coating, but doing both probably would not hurt. I was surprised it picked up that much too, but after running the car I could touch the wrapping and not get burned. Maybe I can get some wrapped/unwrapped temps for you guys. I have a laser thermometer; if I remember I will use it and see.
