New BW EFR Turbo Thread
#361
I'm sending my head to MAP this week... My block bits came back from English Racing ready for me to assemble. These things should be readily available come time for my engine to make noise.
I'm excited to see what kind of potential the 7670 has! So someone please post up some 40+ psi pulls!

A few more:
Fit and finish are excellent. You can see the effect of the investment cast SS turbine side, and the compressor side looks very good as well. No casting flash, no porting needed... The SS turbine housing has a serial number what looks to be laser etched into the side. The machining in the internal BOV shown in the last photo is clean and accurate. The clocking mechanism for the turbine side will be very simple and effective to use, and as you can see, you'll need to clock it for your individual application after it arrives, unless your oil drain and turbine hot side intake happen to line up

From a lbs/min standpoint, BW rates the 7670 at 64 lbs/minute. FP's Red is rated at 60 lbs/min (conservatively rated) and a FP Black is rated at 68 lbs/minute (conservatively rated). The compressor wheel in the FP Red and in the 7670 are essentially the same size -- 76mm. The 7670's turbine wheel is 70mm vs. 67mm for the FP Red. Overall, pretty similar in turbine and compressor wheel size. The FP Black has the same 67mm size turbine wheel as the Red, but a much larger 82mm HTA compressor wheel that the Red does...
A stock Garrett 35R is rated at 65 lbs/minute.
Generally speaking, the ball bearing center section, lighter turbine wheel, and close matching between the turbine and compressor sections should make it more responsive than a comparably sized journal bearing turbo. In terms of spoolup and other performance characteristics, comparisons will have to wait for real world testing...
