Monte, you bring a 5.0 / 150 car to a HSV street car race or you will help fill the field running in the mid 5's. The KOS class here has a real chance IMO and has cool guys. I just want to play with them in this wore out horse and have fun, while we still can.

So I ask, WHY NOT? Is it the coarseness or slow response of the control loop on the cheap computer?

Pressurizing probably changes a lot of flow dynamics, especially after the exit from the TB into the big plenum. If this thing can work at say 10 PSI, and still behave well at 2500 street cruise RPM, that may be good enough with safe tuning.

And here is an official apology to Monte:

The $20K number was an estimate I made in my head after hearing you talk of what it would cost total to put a blower on the 499, and EFI was just part of the deal. And I didn't have a blower then. A $5K running on a car deal came along that afternoon with a carb (elec solved), and I kinda forgot about EFI. So $20K stuck, and I just remembered after over a year. And I hope your Dad is doing OK.
