Hey

I really want to know what I should consider for increasing the boost from 8 psi to 16 psi.

I want to get

1-60 lb injectors
2-smaller pullyes with 8 rib conversion
3-boost a spark
4-Brisk spark plugs
5-upgrade heat exchanger
What else.....


My car is mustang with KB 2.6l 8 psi and built engine.

Upgraded fuel system. Don't know what you're running now but look into a return-style setup.

Edit: oh, and a cowl hood to keep underhood temps down.

I'm running twin GT500 fuel pump and around 12-13 lbs of boost. I have a heat extractor hood that helps with under hood temps. I also added some waterwater to my intercooler to help with heat transfer.

16 psi is getting up there...I'm running three Walboro 255 LPH pumps in a Fore triple return-style hat, max boost of 18 psi at redline. Better safe than sorry and have the redundancy in case one pump fails.
