I've heard from a good source that it is possible to just drop in a fuel pump such as the Walbro 255hp to a stock, returnless LSJ fuel system. Is this possible or will it's extra output overwork the factory damper? Or worse feed too much pressure to the injectors, making proper fueling difficult. The reason I ask is that my mods will not necessitate a return style fuel system with a bigger pump, but I will need a decent amount of extra fuel to feed a healthy shot of nitrous. I don't want to risk leaning out the nitrous shot, or worse the injectors. Thanks!

 

Drop it in and go

 

This seems too easy on a car like this lol. Obviously I'll have to modify the sending unit bracket, but is it really just going to drop in and run fine?

 

whats the whp limit on ours now? i have 270 whp 235 tq whitout my ported head will it handel 300whp?

 

Depending on fuel pressure, the 06+ CObalt pumps outlfow the Walbro 255. ZZP is the first and only company to do and publish a comparison.

 

Which Walbro 255 though? It's unlikey it outflows the HP one. I am looking at the pump in an 04 Redline.

 

still trying to outrun that c6z06 huh?

 

actually he has bigger fish to fry...

 

LOL.

That's all.

 

i gotsa walboro 255 pump if anyone wants...

 

I've never raced a C6 Z06?

Damn straight skippy.

You said you were going to be there right? We have bets that I will take your GTO for a walk in the park. It's pretty one sided.

 

This thread is full of fail..... sure just drop it in and go mah man!

 

Problem is that I have a GSS341, which has a different inlet location. Has anyone ever tried to use it or do they just know the GSS342 works so why bother checking? Couldn't hurt!

 

I hope I can get the built trans that I blew up rebuilt in time... Don't know who you think you are dealing with but I don't talk **** and not back it up, I actually have timeslips too

 

Really? Lemme see one!

 

Ok, you first.

 

Me first what? You said you have timeslips to back up your car. Let me see one.

 

I'll show them to you after... for now keep ordering parts.

 

So you haven't even broken into the 11s have you lol. Figures. One of those teenage kids that talks **** but can't back it up. Idk why I even thought I would get a chance to make a good race with you.

 

(And I am 9 months older then you btw)

 

GSS342, easy install.

 

Thats right it was the c5z06....or maybe its that rsx your trying to beat

 

Both of which I have already beat. What's your point?

HAHAHA. SK360 you're BARELY into the 11s. No wonder you had to blur all the numbers out. Your little mishap on the 1st slip shows around 92 in the 1/8 and in the 4th slip it shows that you are still running less than 120mph in the 1/4. With a ~1.9 60' time (which sucks, BTW) that shows you are running roughly an 11.9ish. Nice try though. You're going to need more than 11.9s to beat me and you would have last year too when you were talking **** on me.

 

** Still waiting on your Time Slips **

 

Guess you'll just have to wait until May 27th to see huh?
