Twin engine GTP project progress thread

BTW the M90 is junk compared to a turbo. It's not even fair.
Lots of HP loss through the supercharger and heat created. I have a massive intercooler on this one and the air intake pipe is COLD, not warm, cold, after running the car hard.

Anyone who knows turbos and superchargers know it's apples to oranges BUT...
We just did back to back changes with very little upgrade. Many upgrade cams, headers change tunes, change MAF, change injectors.
We kept almost everything the same. We see the true difference.
It's night and day. I mean, I feel like at the same boost we make 150HP more.

I expected an easy 75HP gain from the turbo at the same boost but expected 20psi + to really start getting solid performance.
Nope. Stock cams, stock heads, stock block, stock manifolds. (modified mid pipe)
