its 72 degrees right now so im gonna check my boost on the way to my gfs house lol ahh cold weather <3

 

Its in the 30s here at night!

It rips even with no heat exchanger!

 

^Why are you running a 2.8 with no heat exchanger?

 

lol i put 2 busses on a ricer that kept revving at me today(: haha

well yeah im at about 11-12 psi and the gauge will rise slowly a bit at high rpms

 

^cool story bro and mine does that same thing but I'm on a 2.8

 

sorry to be off topic...
Im building a 2.4 lsj wat boost pressure should i see with a 2.5 pulley and a ati crank pulley.
the engine will handle it...

 

Damn your sarcasm!! Haha good to know that the rising boost isn't a problem though

 

No idea lol honestly doubt anyone would know. You may have the same displacement as an LE5 but your head will flow better and I don't think anyone has ever gone that low pulley wise with a 2.4.

 

Yeah it rises quite a bit if you start really low in the rpms but being auto yours would just shift down and you might not notice it. I've floored it with rpms still in the 1k's before (I know not a good idea and I've only done that a couple times) and boost will start at like 8-9 and then rise to 15-16 by redline

 

I see...I'm thinking I might throw on the 2.9 sometime this week maybe if I have some free time and james is ok with it

 

lol..
i know this isn't the right thread but i have a le5 head i do not need. i was told it has lsj springs.
pm me a offer

 

^I'm pretty sure all cobalts have the same valve springs

 

that's wat i thought...

 

wat do u guys rev these 2.4s to...8192 anyone

 

Are you saying someone proved you wrong or that you are agreeing with me? lol

 

Nobody that I've seen revs that high, probably mostly because of the vvt and cam phasers. If you are running an LSJ head though you wouldn't have to worry about that so with cams, springs, and neutral balance shafts you should be able to no problem

 

I've gone to 23 psi on stock springs on my lsj with out a problem

 

that's the plan. and 150 shot of nos...lol

 

I meant did someone say that all the springs aren't the same even though you thought they were?

And sounds like you've got a hell of a build. Mind if I ask why you're staying supercharged or at least not upgrading to a TVS?

 

check out my stroker lsj thread...
tvs will come...
