Re: Outlaw/Sfwd 8 Cars Turbo?
Turbonetics and Borg-Warner as well. Are you doing this for statistical reasons or is this based upon a larger question here? There are certain inducer size limits (i believe 68mm for K-series) which is what drivers are going by; that and their sponsorship deals, if any.
It may be best to ask this on the Drag Racing forum since they concentrate on that sort of thing.

Re: Outlaw/Sfwd 8 Sec Cars Turbo?
Most of the B & K series guys are using the Precision billet GT-4272R because of its proven power. Compressor inducer limit is 72.9mm, IIRC, for Outlaw Street & SFWD. Take Chris Miller and Tony Palo for example, which are running 182 & 183 mph respectively, in Outlaw trim (26" tire) with that turbo, and have gone 8.37 and 8.57, respectively.
The SFWD guys (which are on a smaller tire, 24.5"), are running in the high 160 to low 170 mph range with that turbo, and a few of them have dipped into the 8's. There are a couple of the 72mm guys that are using the Garrett GT4202R, some are BW S372R equipped, but the majority are going with the Precision.
It will very interesting if BW released an new EFR unit with that inducer size (if they haven't already). To date, The lagrest one I have read about or seen is the EFR 9180, which is a 67mm unit. The EFR turbos look extremely promising on paper, but only time and extensive testing will tell the tale of its true potential, at least on our B & K series motors. The 9180 is rumored to be 1000 hp capable, if that's the case, it should make for one badass turbo. A 72mm application would be ****!
