Performer vs Performer RPM 1

[tmoss]

........To be honest I dont know why it ran better with the 70mm, but with the 75mm it would buck like hell anything under 2k rpm's, with the 70mm it wouldnt do that.

in one word - velocity

the air charge moves faster (for each degree of TB blade movement) when using a smaller TB and that fills the cylinder better at lower rpms.

My car bucks like hell under 2k anyways. It really hates being under 2k because of the cam.

I am hoping to get a kenny bell soon. I don't it wouldn't mind a 75mm TB to much.
