If the guys at Underdog Racing respond to me and confirm it will fit (or someone takes a bunch of pictures of the stock pulley bolt pattern/ribs) and @moto-mike thinks he can safely adjust the basemap tune for the 70mm pulley, i'll grab one and have brady throw it on Friday.

I'm not sure if a new belt is needed or not though. Maybe robi or delicious can comment.

anything else i'd need (map sensor?) or should stock be fine?

Sorry for missing this post earlier. You do not need a new belt for the 70mm pulley, as the 75mm setup has a fairly tight belt and leaves room for a smaller pulley. So it is an easy upgrade.

Good luck with the tune.

Drive an automatic, they love creeping along at super low RPM's.

Thanks! Can you share where you found the pulley?

Why not just go direct with sprintex?

Can't find anyone stateside that sells them. I believe @tom@kartboy will be making some soon, is that right?

I meant just order direct if you can't find anyone in the states.

i was looking at the first post, and started laughing at my baseline. 151/???? sorry. wish i'd gotten a better graph print out.

hahaha, i jus looked at that. photo fail

[wrxgoose]

if i go get another dyno at pro-dyno, that'll let me have a new baseline/max. different type of dyno though, read much higher.

what's the most common dyno? I'd say that would b best bet for accurate numbers compared to others if that makes sense

i'd been doing my runs on a dyno-dynamics, but Pro-Dyno uses a mustang dyno.

Oh, ok. That makes sense now. I was hoping the ones that Underdog carried would fit because then I could have picked it up on my way for the install. They replied last night and confirmed it would not fit.

Oh well. No worries.

Exactly, creeping along is the only realistic case. Does anyone really care how much torque they're laying down when creeping? You'll be at very low load, low rpm, and going full throttle at 2k rpm (to actually make the number on the graph) in high gear isn't exactly advisable anyway.

It's useless knowledge if you never actually see the conditions in real life.
