The m62 is a great SC for smaller displacement. That's wut came on the cobalt SC stock. But needs a lot of cooling
When I got rid of the cobalt it was arounder 250 to the wheels with the m62. Had I of kept it and went with the mp90 on a 2.9" pulley like I planned and the built head I still have with meth injection I easily couldve hit 350-375 to the wheels. On a 2.0 lsj 4 cylinder motor
The TVS 1320 which is a popular size for that motor was good to around 400. If someone were to fab up a TVS 1900 I don't c y 400 couldn't b obtained. Especially if u were able to port that out to a TVS 2000. On a conservative pulley, HE, and 50/50 water meth 450 may b had. I can probably go thru and dig up the efficiency charts if u guys were interested
