ok so i want to start a thread for all 2.4 SC questions. because i'm almost positive i will be doing this soon and would like a question or two answered. so i thought it'd be a good idea to have an official thread possibly on questions just about SCing your 2.4.

i'll start with mine, do you HAVE to have a full exhaust to put a SC on our cars or is our exhaust good enough to last a little while. now i know i will not see as much gains as i would with full exhaust but could i do it without doing the exhaust?

 

noo u can have stock... now my q is the idler pulley and transindor pulley the same?

 

what the hell is a transindor pulley? if you mean tensioner pulley, then no,they are two different pulleys

 

hey hunter, i've been meaning to ask you. how are you putting out 265 w/ the 2.2? is it just your supporting mods or do you have an aggresive tune/smaller pulley?

also does anyone know about what kind of numbers i could see with the stock 2.4 exhaust with a SC set up? and how much boost would be ideal without a bigger exhaust and what size pulley?

 

Hunter, is the wiring for the injectors in your how to the same for the 2.4's?

 

lol sorry spelled wrong and do i need both of them?

 

im running a 2.9" pulley. that helps
stick with a larger pulley (3.2-3.4) until you get your exhaust done

yes. the harnesses between the 2.2 and 2.4 are interchangeable. Im not sure if the wires are the same color, but the concept of just finding the one common wire amongst all 4 injectors is the same.

 

Cool, thanks

 

ya thats what i was planning on doing was using the stock pulley. and running low boost. like 8psi maybe. possibly 10, d/k for sure yet.

 

Keep in mind the 265 is BHP not WHP. Hes not actually putting 265 to the wheels. Im not quite sure why he has the bhp listed instead of whp

 

ya but even that on a 2.2 is kinda up there compared to others. and SC not TC. i really want mine to be at or around 250 whp when it's all said and done. thats my goal. i think it's a fairly easy obtainable goal.

 

sigh...ive explained several times. I havent gotten it dynoed, so no WHP numbers, but the interceptor is estimating 265bhp based on airflow and timing, so thats the number i have to go by

 

well i never followed ur build or post so i dont see your explanations. Not to be mean but i dont feel you should post any numbers until you actually had it dynoed. Your interceptor wont be 100% accurate, may not have that much bhp . Then people who do a build like yours and get dynoed and only see 215-220 are going to be dissapointed because their numbers are quite a ways off from yours

 

220whp is 265bhp with 16% drivetrain loss, so thats actually pretty accurate....and i'd say the interceptor is pretty damn accurate. No different than the differences between one dyn and another dyno, as long as people remember to realize its bhp, not whp

 

You can have stock but having exhaust work will only make the gains higher when installing the blower

 

ok cool. just the blower would be enough for me for a little while, until i get more money saved to do exhaust. i know thats kinda the opposite way of doing things (most ppl get exhaust than boost it, but o well)

 

you could be a ricer xander and run straight headers and downpipe. lol jk
also guys i'm pushing 224whp on my sc 2.2.

 

lol ya i could but i would really rather not do that.

a month or two and i will have everything, just in time for summer and to do it during the summer months. damn can't wait.

 

I've been on stock exhaust for almost 2 years now. Kept telling myself I'd do it later. No problems here...except it sounds like anus partial boost. Full throttle and it's mean.

 

I got the zzp shortie header, stock dp but removed cat... stock exhaust but swapped piping that goes over rear axle with 2.5 and a borla muffler.

I also have the lsj tensioner, idler, and bracket for sale
