I am planning on going to a 2.5" pulley and wondering what are the most effective cooling modifications? Heat Exchanger? Water/Meth? BOTH? Thanks guys.

In this order:
Water/meth injection
2cnd heat exchanger (not a bigger one, but a second one to use along with the stock one)
Dual pass plate w/reservoir

Idealy, yes, all of them. But, do what your cash flow will allow, preferrably in the order I put.

IM going to go with my heat exchanger and meth to try and keep the temps down.

Dump in the cooling system some "WATER WETTER" type additive. Royal purple makes some I know

x2. I have the water/meth and a Cobra H/E right now.

If I did it all Over again, I would have done the dual Pass Endplate Option B first>> Then the 2nd Heatexchanger! I'm Currently running the dual Pass Endplate, Dual Pass Heat Exchanger with the stock 1 & the GM Option B Reservoir! She runs cool as a cucumber!

How often do you have to refill the bottle in the water/meth kit? I think im gonna get that first and then buy the H/E when I buy the 2.5.

It just depends on how high you have it turned on. I top mine off like once a week, and it doesn't take much.

how much does the mixture cost you to make?

DTM2188

You can just use window washer fluid for the mixture, nothing special. I'm not sure how much a "custom" mixture would cost though.

I was running water/meth in my Cavalier with the M45 blower (which was not intercooled) and the best results I found for both cooling and being able to increase timing without getting knock was a 60/40 Methanol/Water mixture. If any of you guys are running meth it can be bought very cheaply in the form of "Heet" which is a yellow bottle of drygas sold at any auto parts store or even Wal-Mart. This stuff is about 98% methanol.

Don't forget about the Cry02 cooling system.

Install a bulb in your intake and or spray your H/E.

wait sorry if im being a big noob but did i hear that right? window washer fluid is water/meth? so you use that?

607Motorsports

you heard right, windshield washer fluid is actually about a 50/50 mix of denatured alky and water so it's a very viable option for Alky kits. Many use this with great success, plus it's cheap and very abundant.

On a stageII tune with a 2.8" would I see any TQ benefit with getting meth injection?

Acidangel_5.0

i wouldnt even bother with a 2.5..

R33P3R007

anyone try the new RainX washer fluid.... lol.

AdamRedSS

wow, you learn something everyday! what about the 2.5 acidangel?

Acidangel_5.0

not worth the risk for a few more fl/lbs

just keep the 2.7 or save up for a FI swap..

AdamRedSS

yea, haha im just horrible at saving money over long periods of time! otherwise I would sell my supercharger **** and buy a turbo! but I cant save 4,xxx dollars over time. lol but I may grow up some day!

R33P3R007

not...^^^^

AdamRedSS

or maybe ill just run 2.62.....

yea...your probably right oh well

I have been woundering if anyone out there has or makes a FMIC for the ss/sc, i would think that would be another viable altnerative to adding another heat exchanger and meth injection. OFcourse i have no idea how meth injection works and were in the heck id purchase more of it when i ran out hehe.
