BUBBA · **How far can +40 injectors take you with...**

a 3-bar MAP/+40 custom calibration on a 2.5 liter? Just curious if anybody knows a rough estimate of this. I'm currently running around 20psi of boost. Thanks.

With race fuel a rough max estimate may be 22 psi, with street fuel 18-19. lots of other variiables like how much air you're flowing, puel pump, intercooler, etc.

I ran 20psi on a stock fuel system, ex. AFPR, on 20%'s.

I'm also running 20psi w/ +20's w/o a problem on 2.5. I would think +40's would take you at least to 25psi or more

The +40/52lb injectors are good for 300hp @ 80% duty cycle.

I've seen a 3 bar map 2.5L set-up make 340 hp and 388 ft lbs... all on 93 octane pump gas at 25 psi boost.

How the heck are you doing all of that on pump gas? That's really impressive.

Same way this car did this with +40's, stock ECU, and olnly 35 psi base fuel pressure! Its still pig rich up top!

You can make alot of power with +40's.

Hey Larry, what's with the big dip around 5800 rpm on that chart?
