750cc injectors

[TnSlowSrt4]

Can you do the 750 injectors without a fuel pump and without the return kit on a 50 trim kit and still get close to 400hp??

[Soldier101]

get a fuel pump, the stocker wont keep up with the injectors,return kit, not necessarily needed

[Nick@AGP]

The stock fuel pump won't be able to supply them.

but the return kit is not needed to make over 400

correct.

The shop car didn't have a return line and threw down 490 HP.

the shop car had higher compression pistons though, right?

You will need a fuel controller such as DTEC or SAFCII. The AGP fuel kit is the way to go, you get eberything you need. If you just bolt on the 750's to the PCM it will run like shit....way too much fuel.

I went with 650CC injectors, Fuel Return kit, and a Walboro fuel pump. I am hoping for 370+whp on pump gas with my 50trim.

yeah i already have a afc2 but i was going to run the stg 2 injectors then i thought screw it i want more hp so i want to get the 750s

true. 8.8:1 Wiescos.

[Nick@AGP]

But how does that have any effect on needing a FPR?

[skipdogg]

It doesn't.

Ok, so when I go 50trim, is Walbro Fuel Pump and 750c Injestors be good enough for 380-400+HP on pump gas without a returnline??

At what point would I need the return line??? Thats what I dont understand.

We've done well over 420whp on pump gas without a return line. We also did 460whp on C16 without a return line. I would recommend that if your goals are over 450whp, a return line will be needed.
