The weather sure changed, didn't it? We pulled 320/302 on STM's dyno yesterday, in the midst of the heat, with a Works TBE (w/cat), MBC, and a Buschur FMIC.

How does your car feel? Do you notice any lack of torque down low?

Definitely no loss of torque ... she pulls hard ... can't wait till this damn rain stops so I can really get into it!!

So you pulled 320WHP ... any cams??

<grin> Yea, I was out earlier today spinning tires.

No, no cams, just the few basic mods I mentioned at 23-24PSI. We were surprised by how well the car ran. Em thinks that low rotational mass was partially responsible for the results. I recall David Buschur testing lightweight rotors on his dyno. I even searched for the thread, but couldn't find it for the life of me.

I saw your car at the shop the other day. It really looked great.

You running light weight wheels too ... what rotors??

Baer 2-piece rotors on all 4 corners and 15.5lb RP-F1s with stock Advans. We have another set of Advans waiting in the wings. Once those wear out, I'd like to find a lighter tire.

This month's C&D has an interesting high-performance tire comparison. Dunlop Z1s, a forum favorite, were the number one pick. The number 2 finisher, Hankook Evos, were some 2lbs lighter. That's no small chuck of change, given the tire's location relative to the hub. I will definitely look into these when the Advans are gone.

I wish I could find that Buschur thread. I bet you could get more power to the wheels with a lighter wheel/tire combo.

Wow ... those Advans are super light ... NICE!! How much did they run you?? I always forget to factor in how much rotating mass can effect HP. My wheels are freaking 21 lbs!!
