[s-cars] Rods and high HP: Oil Issue??

[Lewis, Gary M]

Assuming one is running close to the limits (boost and timing), for a street car your synopsis implies water injection, as the quality of pump gas is impossible to control.  

Funny, I keep coming back to this.  I have been working on an Aquamist 2d in conjunction with the FMIC.

Thanks,
Gary Lewis
