1000cc injectors

I would say since you are not pursuing e85. Injectors should be last on you list after all other mods, IMO.

Yeah, returnless and set at 58psi. We now have a boost-referenced FPR and base set around 45 to get the injectors to work good at idle. We could squeeze more pressure if needed but he's going to have me do cams and some other tricks and see where it ends up first.

That's what I'm talking about...... Sonic's are a long list of mods away from higher rpm. One day, I hope to get there. I've got better rods/pistons ready for my build, but it's gonna take cams, valve springs and turbo to put 'em to work.

Well in that case I probubly wont do injectors. Ive still got exhaust mods I want to do. Get my tune. And was it you preloader that did the thread on porting the intake manifold? Im wanting to do that too

FWIW, on a local cobalt with a turbo kit added we are using ID1000's, E85, a return line setup and a walbro pump, car is making right near 500whp at 27psi and has fuel left. Injectors that big are just absurd on this tiny engine, and we don't turn anywhere near the RPMs as the cobalt does, high-rpms cut down the injection window and drive up IDC more than any one other factor at that point.

Agreed with all the above, the factory 42lb injectors are great and I used them to get a ton of power out of my supercharged cobalt way back when. Plenty more than 99.99% of sonics will ever reach. On pump gas though, if you are using E85 you are diminishing capacity by nearly 30% so you get there quicker.

I didn't know you were over here. haha.

Josh's car is just insane.

I'm running E85 on my Cobalt with 80lb. injectors, and it's plenty fine. I'm still supercharged, running a 2.7. I ran 60lb. on pump gas, this was before the 50lb. were out.

Yeah, bought a sonic for the wife so i'm here getting ideas and buying a few parts.
