Me, my sister and my friend were going to Village Inn to eat. The WRX has an MBC@16 psi and intake. We see our other friend there, he has a 1992 Supra Turbo, that he basically rebuilt himself. He said he had a Greddy turbo (didnt tell me which one), and tbe exhuast and other little mods. So we decided to do some rolling runs. We went from about 40 mph to 110 mph. He pulled really hard at first and then it basically evened out by 80mph, with him going away little by little.
He was spinning his tires at 40 mph and his car squatted. I had 2 passengers and so did he. At first I expected him to be faster, but then he told me he was only at 10 psi. He said when he ran 25 psi on the same turbo, he did a burnout at 120 mph on the highway.
We didnt do any 0-60 mph races, though im pretty sure he would catch up by 60-70mph.
Anyway it was pretty cool to race him. He ran 12.0 sec 1/4 mile here in Denver, with more boost, which would be ~ mid 11s at sea level i guess...
