where can i get a 2.5 pulley for my M62? or maybe even something even smaller?

 

welp. what pulley are you running now?

and just in case, ibtl

 

i am on a 2.7 now. but i want to go as low as i can, add cams and a ported head, then do meth....or E85.

 

put the belt right on the snout. Dont need any size pulley.

 

i guess theoretically....hahahaha

 

all a pulley that small does is create a butt load of heat. the blower is already being overspun with a 2.7" pulley. if you really want to try it you should have every cooling mod you can (dual pass, option b, 2nd heat exchanger) and either meth injection or e85. even at that its just horribly inefficient, more power could likely be made with the 2.7" and an aggressive tune.

or just drop a tvs on it.

 

^ this, there is an efficiency curve and at a certain point the heat produced by spinning it faster overcomes the gain in airflow.

 

I understand the reasoning for this if you plan on running stock cams, only revving to 7k, running a lot of methanol at least, e85 of available and possibly dual pass and whatever else. I don't see why anyone would want to get cams and rev the heck out of the m62

 

ok. well maybe not then. everyone says its a really bad idea. time will tell what will be done.

 

Where is everyone in here talking "mad ****" like you are claiming on Facebook OP?

 

Oh no, is he making claims that aren't true. Must not be in the 3 I belong to.

 

Yeah he is This was on the Cobalt Nation buy/sell/trade page

 

I'm on that one, will see what's up.

 

Well at least this time they were pretty much agreeing with what was said in here.

 

OzzyRuleZ thanks so much for looking back and forth between my cobalt nation and my forum posts just you can post something meaningless on my page. sarcasm on cobalt nation man. i guess ill just go back there though and keep lying for whatever odd ******* reason. if your not gonna help answer my question or give me any meaningful advice, then please just dont answer what soever.

 

we are answering your question, we are just giving some constructive criticism on why it would be maybe not the best idea to put such a small pulley on m62, and then you go say we are talking "mad ****".

 

He PM'ed accusing me of making stuff up about his "sarcasm" on Cobalt Nation, so I screen capped it. Yup I'm making this up. Kids these days

 

alright my bad guys. i should have chosen my words better. if you look closely, the first person that replied called me a "welp" in his comment. i should have said, i already have one **** talker or something. seriously, is all this trolling necessary?

 

You're spamming the forum asking very, very uninformed questions and not liking the answers.

The forum has been around for a decade. Pretty much every question you've asked about your pretty common bolt on mods have been covered a lot. There has been a ton of people that have figured out what works and what doesn't with our platform. So when you ask a dumb question it's really just because your lazy and you'll get a dumb reply.

We're not here to hold your hand through every step of modifying your car.

 

Easy dude don't get all raged. He didn't need to post on your thread because others had tried to give you the same advice he probably would have but you weren't wanting to listen that much. You can put whatever size pulley on you want but it's kind of like trying to boost a stock k04 turbo over 30psi- all it does is hurt, not help. Listen to those trying to talk sensibly to you. Or go your own direction, that's your choice, but don't wonder why you intake temps are sky high with a super small pulley. If you really want to make the car fast you have to go with a tvs setup or turbo swap it. Or just enjoy it for what it is with a 2.7 pulley on it.

 

my honest goal was to see what i could pull of with an M62. i have heard of 400hp cars on a stock blower and that what the ultimate goal. yes i know that the 2.5 creates massive heat, but i was gonna run E85 or meth so i didnt think it would matter. but after everything i have been told. i think my 2.7 pulley is gonna do just fine.

 

i would like to see this 400hp m62 car you speak of........

 

Turbo Tim at ZZP man. of course i never asked him about it myself but its right here on there website. here is a link. they talk about it under the cam section for lsj's. it says specifically he was using the stock blower. so there is your answer.

Ecotec Parts LSJ Performance Cams

Supercharged:
-The Stage 1 cams are recommended for most supercharged builds, these cams will raise your powerband about 500rpm.

-The Stage 2 cams are the next step, they will raise your powerband about 700-1000rpm, they will make peak power around 7500-7800rpm! They will require an ATI balancer to help reduce engine vibrations at the new high RPMs.

-The Stage 3 cams are recommended for all out race cars, not intended for street cars due to their high rpm powerband.

They were designed for our all out drag car with the 2.4L stroker engine. These are the cams that Turbo Tim runs in his 400whp, stock blower, 2.4L stroked Saturn Redline that makes peak power at 8500rpm. So on a 2.0L they should make peak power at 9500+rpm which would require a highly modified valvetrain to support.

 

FYI- those shop cars had every bell and whistle on them to achieve some of those numbers and probably didn't live long. No way you are going to make 400whp on a m62 and it live long, and theirs probably ran nitrous. Those motors were set to kill and after the dyno they probably got dismantled. If you can do 300whp that's pretty good to be driveable.

 

i honestly dont know man. nitrous or E85 or something. but i was gonna add the bells and whistles anyways. thats what you have to do if your goal is power on the m62.
