    Back to the OP........

    15% vs 17% is really going to come down to how well you can manage the heat generated AND what part of the rev range you will be realistically driving in.. In Texas I would never suggest going with the 17% as the heat generated could be excessive. You could stay well below the upper rev limit with the 17%, but what fun is that.....LOL

    Yes I agree 100% ^ and I would never put a 19% on a car that I wanted to use as a daily driver.

    Like Colin said you can make much more power with the other mods like BVH, CAM, Injectors, Meth, Header and a custom tune done correctly. :Thumbsup:

    Sure you can run a 17% or 19% pulley but you wont be running it for long at red line with all the heat it generates in the Eaton M45 SC.

    Man I've been missing all the fun.
    I like it here because everyone is helpfull. Dave has always gone out of his way to help people on this sight. A lot of good advice has been given but Rogue made an off the wall statement that was directed at Dave. You want a 19% pulley fine but you better get a more efficient Intercooler, maybe meth, oil cooler(inter engine times will go up), bigger injectors, cam, ect....... To say a 17% pully is 2% shorter life span and 19% is 4% compared to a 15 is well............................... stupid. I read a lot before I went with a 17 I knew I was pushing it but I had planed to do more before now just haven't had a chance. 19% is over the top unless you plan on spending some big money.
    Rogue If you don't belive me when I get home I will do another data run and post the temp delta. Oh yea even with the two size shorter SC belt I still get slippage some time.








    Oh help I'm starting to sound like Dave! :frown2:

    One more point...
    If you run redline with the a pulley, the oil temps spike...
    More a result of the water pump cavating (forming vacume bubbles), which results in temps going up in the block...and the stock oil cooler looses coolant flow...
    So I suggest again...
    15% for track...
    17% for more of an easygoing street driver...
    19% if you like big $$$ and breaking stuff....

    Yeah, I live in Dallas so heat is a major concern for me. I will eventually be going with bigger injectors and probably a tune from RMW. I just picked up this little puppy for a song so it should help.

    The welds on the old Forge I/Cs had a tendency to crack and leak... Pressure test that puppy!

    Yup for and for a 1st Gen intercooler upgrade nothing beats the OEM GP intercooler.

    Yes they are pricey but they are worth it.

    This has been proven several times year after year. Yes, some tests will show something better is a staged test environment for one or two runs but in the real world the GP one recovers the best and out performs the others in the end.

    If you add Meth everything stays really cool. :ihih::devil:

    GP is the best unless you happen to come across one of the DOS copper core I/C's... They are extremely rare, but do offer a little more than the GP. ;)

    But with meth (bottle not baggie) the OE S I/C is good for a hundred or so HP over stock. ;)

    If you run Meth do you need a bigger I/C?

    No...I'm curious, why do you ask? The meth cools better than the IC, it's not dependent on the IC at all. With meth you can get by with a smaller IC.

    Well thats what I thought. For now I plan on getting bigger injectors and Meth. I just wanted to make sure I did not need to add a bigger I/C to the list.

    Nope, if you get meth you wont ever need a bigger I/C. :)

    Yeah, I've read that the GP is better, but for $300, the Forge unit is hard to beat and should perform a bit better than the standard IC I'd imagine. I've also been researching some meth injection as well, any suggestions on a decent system around the $500 range?

    The Howerton/AquaMist systems are the best... A little more saving might be worth it, they are only a couple hundred more.

    I bought an Alcohol Injection Systems .com kit long ago, ($600) and shoulda gone with the best first time around... It was a pain sorting all of the problems out. :(

    The meth does cool better than an IC, but wouldn't using a "better " work IC further help cool the intake air temperature? I watched a video on YouTube of a meth system cooling from 270 degrees down to ~90 degrees which was around ambient Temps. Wouldn't starting lower help the meth system bring Temps below ambient? Living in Texas, ambient Temps during the summer is around 108 degrees so I figured any extra cooling would help.

    Is it yours? I figured someone on here could identify it.
