2.6 Pulley Questions
This is good info. I'm on the fence about this also. I have a 2.6" pulley to bolt on but just unsure if i should. I run meth but after talking to ralli he ran a 2.5" with meth and i guess with the two it created a lot of cylinder pressure and ended up cracking a sleeve. Definatly don't want that lol. And you arent supposed to do back to back pulls running such a small pulley so it has me concerned about when i go to the track. Can anyone chime in on experience?
I see both sides.
I've whomped on two 2.7/60lb. cars with a 3.06/42's before. Cooling mods and tuner were key, also having a properly done cooling system.
Don't neglect efficiency!

You made more hp but less tq with a 2.6? Usually it's the other way around lol. Or same hp with more tq.

Every 2.8 pullied car I know have pulled on 2.6 pullied cars w/o meth, all of them properly tuned as well of course. I have also seen every one of those 2.6 pullied cars w/o meth blow their motors.
No way you are going to run a 2.6 pullied LSJ without meth on 22* of timing on pump gas without blowing the motor after a few runs.
As it was suggested, you could also run E85 to help prevent detonation but you will need bigger injectors.

. Is meth enough, is the question thats burning in my brain
hp is an equation that relays on torque as one of the variables.
as far as doing back to back pulls... with any pulley smaller than stock you need to watch your IAT2's// around 160 you should back off and let her cool down, if not things can/will happen

do not need, there's no point in using it without higher octane though
jeeze this thread went to ****...
when your iat's get to about what? 120 degrees it starts lowering boost in an attempt to not blow your motor, if you did blow your motor. (fyi, my definition of "blown motor" is ******* **** up)... you were beating on the car pretty hard, or your tuner messed with the max boost on your IAT preference.
you don't need meth on a 2.6, just alot of cooling mods, hypothetically you can have maybe a h/e, but you would be seeing 90% boost most of the time. If you are unsure of the 2.6 and think you might blow your **** up, ask your tuner for 75% max boost on 115 degrees IAT.
please be smart and get 93 octane with full cooling mods and proper exhaust components.
2.6= maybe 11 tq and 9hp, with top end lowered (just a tad)

^^^^^^^ u don't need meth on **** technically but is recommended. **** I put meth on a stock pulley and tuned for it and my car was quick. But that's. Beside the point. If u want power and want a smaller pulley id only go with 2,6 and have a rev limit of 7k rpm. Full exaust intake, 60s. H.e and I didn't run dual pass but is recommended. My iats after a lonf pull without meth on a warm day was about 145-155 and a warm day is like 85+....a stock tune don't pull boost till it sees high iats above 170 I think not 100% sure. Wut it does do is pull timing by a perce.tage of rpm and cylinder air mass.. wut I do if I tune for meth I have a afr of 11.8+ depending on my customers driving habits and there wants. So if u like racing, get meth and someone to tune u......
And again, more then likley u ill always be over ure 115iat2 mark so don't even do the 75% mark lmao. If u do stay with a 2.8 now if u have iats not iat2s I hope u don't even get on it way to warm lol........ but this is my view. Btw 75% would be like 14lbs I think.....
50 50 is,by far,the best mix for cooling, but ran 100 meth when I was on my 2.6 for about a week and. I was runnu.g 11.9 and it felt better with 50/50. My iat2z were lower with the mixed meth also so 50/50 wil get u better results.
Good to know. What size nozzle were you running?

I've been on a 2.5 for over a year or so now. Best advise is get the gauges to monitor the important vitals. Know when to let the car cool off and you'll be safe. Alot have mentioned here, and Ive done it. Meth isn't needed but HIGHLEY REC. They want you to be safe. Just build the car right. Do all the supporting mods and you'll be fine. I dont beat on my car back to back and its fine.
Also ive been on the dyno on 2 diff pulleys. The 2.5 made more hp and tq then my 2.7, a peak of 5 hp more and 20 more tq. The 2.5 also made more hp sooner in the power band, avg of 10-20 more. I did it to prove to myself and now I know. I will stay with my 2.5.

jesus christ some of you are stupid.
spend all of your hard earned money on cooling mods, apparently saying **** it to power.
it's called torque people.
"a bigger pulley can make more power" yea. at 7k rpms. what happened to the 2.9 car that raced a properly tuned 2.6 car? oh the 2.9 car got it's **** kicked in. some of you have ZERO room to talk about tuning. period.
in short. **** cooling mods. make power.
