As the title says, what are the advantages if I was to buy 60s with a 2.8 and a basic meth kit? What kind of additional power can I expect? Would it be worth the ~500 dollars for the upgrade? Thanks for any info.

Theres been alot of threads about this lately...

Smaller pulley = more power.
Meth = Cooling + Efficiency (Power)

If you are planning on doing any more than a 2.8, NO... You can run a 2.8" with 42.5s espicially if your running meth.

If you wanna end up running a 2.6 or something, and you overall would like more power, Then the 60s would be the way to go.

From what I have gathered, it's not the heat issue when it comes to a 2.8 with 42's. It's the fact that the injectors are past maxed out. My injectors (42's) were running at 110% IDC on the GM stage 2 tune.

lucky you. haha im at 122% on a 2.9 and stage tune

And this equals less power, correct?

nah, just means the injectors are being overworked. an injector is a solenoid, were just exceeding its rating for how fast it can open and close

Go with 60s and look into a return style fuel system. You dont want to go through what i am(look at sig)...

a return fuel system isnt necessary for a 2.8" and 60s. not until you go TVS or turbo is that necessary.

I also am debating on whether to go with methanol for my 2.8" and 60# set up. I have a front mount h/e but my iat2 still hovers in the 135-140 range after a 1/4 mile pull in the summer time. (i dont beat on it when its cold)

Isnt necessary but beneficial and no starving #4 at wot.

You dont need a return style for that..

And you shouldnt run anything under the 3" with a stage 2 tune..

You will need a custum tune.. But it will run, and my IDCs are NOT even 90%

If you're running a 2.8 on 42s, I guarantee you that your IDCs are over 110 and if they aren't, your car is leaned out way too much..

No its not..

And no.. its not ...

pw is more important thnan idc's becuase thats more or less a calculation. Whats your pw up top.

flash13brandon

How do you know your IDCs aren't over 90?? I thought you couldn't open HPT. I switched back to 42s for a couple days and my IDCs at WOT were 134...

you IDCs will be a lot less obviously with the 2.8/60s than with the 2.9/42s. also the meth will help reduce your knock if not eliminate it all together, plus add a little reliability and a slight power increase. you could possibly run a 2.8 and keep the 42s if you were to run meth. but personally, i wouldn't. so IMO, an upgrade to 2.8/60s/meth/retune. is worth the money

When i was with my tuner i sat there and watched the logs..

Im not sure what my PW is.. i know he took away some power so i wouldnt go over my idcs (pws).

BoostedYards86

really and how did he take away power?

ShortStack

Dude i have no idea im not a tuner.

Probly cut back fueling a bit... would be my guess?

flash13brandon

Ok that makes a little more sense. Lol what did he do to take away power? Limit boost

ShortStack

yea in first gear.

i think he means its not as an agressive tune as it could have been

flash13brandon

lol i know. But 90%...come on

EXsoccer1921

iTrader: (14)

90% what?

hmm, seems a little weird to me. first gear puts virtually no load on the car since its over so fast. The two biggest oplayers for power on these motors are timing and afr. When you tune a car for less power generally its a more rich tune. That the reason for asking for the pw, that way you can see if his pid was off for idc's in hpt.
