Ok so I was wondering has anyone ever tried to use these before in the cobalt ss? http://www.trickflow.com/partdetail....1&autoview=sku
I got a guy with 4 and hes willing to sell them for 200$ for all 4 of them. i might pick them up and see if they work or not.

 

There are two guy's i know of with 1000's.

One has the map for them.

good luck.

 

Hmm. I don't know if anyone has. It's make some badass power I'd hope. I say go for it. You could start a new tread Everyone here just plays "Follow the leader"

 

Yeah I know right if they work I would just need some help with a map for them. I aint too good at doing that. But maybe area will help. If they fit and work I would drop to a 2.5 pulley on e85 and see what I dyno at. I get to take a look at them on sunday and I get to bring one back to my place to test fit it.

 

Those are low impedance injectors. You can't drive them with the factory computer. You will need to add a conversion box($300). Your next issue will be trying to run a short enough pulse width to idle at stoich. You will need to run a full boost/vaccum reference fuel regulator to bring the pressure down to about 40 at idle and then you might be able to make them work with E85.

 

Good info matt. What do you recommend he does then? Stay with 80# injectors and go with either a BRFS or return style?

 

zzp makes a brfpr to help you with your quest to make injectors work

 

in 3rd I am at 105% idc I know I have to rais fuel rail pressure the only question is zzps boost ref or ottps rsfs. I am debating on both. Or I will put together my own one of the two. I need low enough idc that I dont go pig lean in 4th.

 

I don't think I've ever seen a lean pig.

 

i say lean pig cause my car bogged down when it happend and sounded like a grunting pig kinda. Everything is fine till I get to 4th then top of 4rth at 6200 rpm it jumps from 11.7 to 17.1 and the maf is only -2 so it should be that far off. I know I am out of fuel and need more. you think the boost ref will help at all? Also can you make the boost ref a return style fuel system too?
