We have found that very small amounts of methanol pre turbo works well, but you have to be very careful about the amounts and making sure it is the most homogenous mixture possible. You essentially want the cooling effect with zero liquid present by the time it reaches the compressor. I would...
60-1 is ~59mm inducer and 75mm exducer, maximum flow was around 60#/min...I do not have an efficiency rating for this wheel...but my guess would be in the 74-75% range at its best.
The 62mm MFS wheel is 62.5mm inducer, 82.5mm exducer, peak flow is just shy of 75#/min and peak efficiency is 78%...
Thanks for the kudos...I really love to get back to my roots and try new things with these cars...hopefully mine will be up and going later this year, I miss the ol' girl. Owning mine since I was just out of high school in 93, and it still gets my interest and imagination going after all these...
The 60-1 is a great wheel, even though it is ~25 year old technology. It is a very good "high volume" compressor despite its age. My personal '87 has one on it to this day....hard to beat for a "street" car! I ran 7.18 @ 99.7 to the 1/8th with 60-1/ptrim .63 turbo on 14 psi....was totally out...
The main reason for this change over my previous compressor wheel choices was to lower the compressor outlet temps as much as possible at higher boost pressures. On some other applications we have seen 30-40*f drops in discharge temps comparing to a wheel with a primary/splitter blade design at...
Keep me posted Toby, I am always looking for feedback on our products. Thank you so much for the business it is greatly appreciated!

Tommy is the "data king" for sure...I am super excited to be a part of this test, BorgWarner is on board with us every step of the way and we will have some pretty useful data to share with the Buick community over the next month. Lots of good things coming in the near future ;D
