so......................has anyone been able to measure the intake temps yet for the 2.8, 7, 6 pullies yet?
my curiosity (and im sure plenty of others on here) remains if i can safely use the 2.7 pulley w/o any additional mods ..... its not like i'd run the full 7 psi all day anyway, just rarely i'd give it a spike.....

i imagine your IAT's will be slightly higher, but not too bad. That's where you start getting into things like alky injection, which I highly recommend.
I was a retard, and now I'm permanently banned.
I am running the 2.6" pulley dialy now with no alcohol injection (its waiting to be put back in once the throttle body plate gets here)
I was just to lazy to switch it back to the 2.8" pulley i have when i took the alcohol kit out to get fixed... and its been running fine... i do feel less power after a while with the computer turning down the timing and heat soak but its not all bad... you should be fine though...

All dynos run on a Mustang dyno
it will be high as the gm s/c pulls timing pretty bad.
i seen on turbo cars upwards around 1600 degrees.
1600 degrees for intake temps?? LOL

oo damn.
i thought we were talking exhaust temps.
(standing behind /working on a turbo z24 with no cat running rich last night doesnt help)
i am sure around 200 degrees at least!
Well I finally got my scantool today....So i just drove around and beat on the car a little and my highest intake temp with the alky and 2.6 pulley was 132............I'll post back when I have more info without the alky kit

ELIOT. Now.....boosted.
bobby, i been out of town for a few days and probably will be for another week, but what you should do is put on the 2.7 and drive it around for a day w/ alky off, and then w/ alky on
i'll make it up to ya i promise!

Ok so I put the 2.7 back on...man I feel slow now lol......ANyways....I drove home from work with the scan tool on and it was about 80 degrees out today...At least it felt like it...and very humid...
I started out with 84 degrees intake temp. I drove it normally half way home and the highest my temps went was 120. Then I started getting into town...and started beating on the car a little more. Highest temp I saw was 156. Now it may of gotten hotter if I had to drive further. So once I saw the 156 I turned the alky on......After that I never saw higher than 140.....
Now maybe had I driven around longer I would of seen hotter intake temps...but I didn't feel like driving around for no reason......
Oh and also...my a/f's were in the high 11s with the 2.7. My timing advance ranged from like 20-26 according to the scan tool and that was at WOT so anyone care to explain to me if thats good or bad then be my guest
Now when I switch back to my 2.6 pulley then I'll do the same thing and get all the info.....but I hope this helps somewhat to you all!

yea the ones that fats02z28 is making...
bobby - thanks for that info man... helps out alot for tuning on this twin charge set up for me... untill now we just had to guess at the intake temps... also which scan tool are you using?

well at least you know it is working.
you are still on the m3 injector?
are you going to do a comparsion between the injectors?
Yea I'm gonna test out the 2.6 next.....THen swap injectors and see what a difference they really make if any
Viper- Its not my fault I wanted to buy the pulleys! Besides...as long as I'm faster than you I'm happy
haha

with my stock pulley at 80 degrees temp my intake air temp was around 170-190.
with the 2.5" and water injection its arond 70 at 5K rpm.
