Fuel and Boost

[smookthis05]

Does adding more fuel generally make for more boost? Because I put an HX40 on my truck...and with an airdog 150 and edge at wot on 5 my turbo was only getting 30 psi...now i thought i would be getting at least 40 if not 45...is this normal or do i need injectors for more fuel and boost.....

I have a modified HX40 on mine, and I can only muster 38PSI out of it. I had to add a boost elbow to it to get it to there, prior to I could only get about 30
I called the manufacturer, they couldn't explain.

BTW, I made 425/899 with Bd3 inj.,and an Edge comp.

if yours has a braded hose coming off the waste gate either clamp it or remove it and see if you get more....yea im thinking of just going with injectors and seeeing what happens

Typically the morefuel you get to the cylinders (larger injectors) the more boost you should be able to create. That is long as you wastegate is dealt with properly with either a boost elbow or such...

For a stock Hx35 I've got with a Edge Comp I'm pulling 32-35 PSI easy...
