This engine was built for boost but it ended up being on the bottle. It now is Turbo and I have not tuned the on it just yet. The most boost I’ve seen so far on the Transbrake is 8 psi at 3500 RPM I’m sure it’ll make 20+ pounds or more if I let it. I have not driven it yet. Right now its getting a new hood and some other minor stuff. After that, I will start tuning on it. Most likely it will be a couple weeks. This is not a max effort build this is my street car. 1000 to the tire I’ll be good with that. Im thinking 15psi should get me there.
