There’s another single turbo isf on Instagram. His is under the car inline with the exhaust. Based on turbo placement, it has to be easier to go under the car. I wonder how this guy wrapped both headers to the turbo in front of the tire?
My buddy Mike turbod his ISF. Its mounted under the car. Pretty neat setup. There is one in Australia that did the under mount turbo as well. It runs very good.
The underbody single turbo makes 500 whp on e30 with a tune I think, running 5 PSI. I’d suspect similar numbers for any similar build. The fuel system needs upgraded.
He retuned it after that. At that time he had just unplugged the battery, so everything was reset. He is making more power now. Runs hard AF. I think he now makes 542/565 at 5 pounds. He might go up a pound or two, but for now its good.
