Not even a tenth of a horsepower.
Power is related to the engine breathing capability Displacement X RPM X Volumetric efficiency.
If you had fuel pressure drop issues like with using a fat turbo with huge injectors, that would fix it tough.

i do have the blitz compressor but it probably wont make a difference sending the fuel from stock to perrin's fuel rail

correct. it won't deliver more fuel, and it if did, you'd have tuning issues.

It was a great eight year run, but it was time to focus on other things. I'm still selling parts on eBay under micro*image seller ID and customers can still make requests for anything specific.
