how much psi would my 2.4 be pushing with a 2.8"pulley?

 

mines at 12

 

i got the gm stage 2 (3.0) 10 psi

 

what does everyone recommend for the 2.4? like what size pulley would be best for a DD? for it to still be safe and reliable. i know i will have a good tune through trifecta so im not worried about that

 

ideally you would see anywhere between 13-16psi of boost on a 2.8. However, you are also spinning the rotors at a faster rate, so you would most likely get heatsoak a lot easier. On your whip, xander, I would recommend not going over 12 psi on your internals. A 3" pulley would be fine, but it's really up to you.

 

ya i was think the GM stage 2 pulley even though i just bought the 2.9 lol.

 

25psi go big or go home lol

 

considering from what I've read, that even the lsj block (stock) can't stand more than 25 psi, he'd more likely see a piston shoot through his tailpipe at that boost

 

Dude just do ur research and u'll be fine. I wouldn't suggest goin lower than 2.8 without supporting cooling mods

 

i have been doing research and i hear such mixed opinions its ridiculous. ppl say ill be fine at that boost some people say the block cant handle it.

 

Being tht ur a 2.4 u'll be around 12 pounds on a 2.8 pulley. We ain't the same as the lsj motors, they get like 16 pounds on that set up. Ima doin a 2.8 and with NICE mods lol and I'm fine and running perfect. Ppl who go and blow there motors are the ***** that can't drive or the ones tht throw a 2.6 pulley with no supporting mods

 

well i have a 2.8 on the SC set up i got. it has opt b. ready to go with a aftermarket h/e. i have a CAI and i already have 2.5" catless exhaust. i just bought a 2.9" though. ill run that one first and im auto

 

U'll be str8 bro.

 

thats kinda what i fugred because joseph (dragonfiress) has a 2.4 balt and he has ran a 2.8 for like 8 months now.

 

Yea I kno him. Well let me kno how the build goes bro

 

I'd pay money to see a Piston...shoot out of the exhaust pipe.
