We can run up to 15PSI on 93 octane or higher non-intercooled. We only need to run 10PSI to make 171 WHP on 91 octane with no timing retard. 10 PSI is also our magic number for CARB. I agree, no reason for you to feel guilty about those numbers, you did the best you could.

After reading this:
I don't feel so guilty for asking what boost level are you running?
If you going to compare them directly, let's compare it psi for psi.

GM has had some really great ideas and some bad ones. TBI too me is sort of the result of carb people going to EFI.
"We really dont want to do 6 or 8 of these damned things, they are epensive. Plus we dont have an intake setup for them yet. But we can bolt this POS here onto damn near any 4150 style intake!"

Is anyone else interested in seeing a few more setups with a coldside 45 or 62 and a 3071? Puley the blower for about 8 psi and watch the 3071 act like a 2560. I wonder if the blower would become a restriction? On one hand I doubt it considering that with a PD blower it will just get better filling on the inlet side, but I am not sure.
Funny stuff on blowers lately. I saw a traditional centrifugal setup for a bit more $ than a Rotrex kit off Kraftwerks. They claimed 205 crank HP while making 165WHP, and they ran 10 psi to get it as well IIRC. If these cars have an 18% driveline loss I will be VERY surprised. My guess is more like 12% with a Torsen.
