I believe they are mid mount on our cars. They get extremely hot and dont hold PSI from what i have heard. Also, a lot of tuning issues. A guy with a forged 5.7 single turbo just hit 900rwhp on a 5.7 block. But the cost/time/issues are so much everyone just goes with a supercharger. A builder i know wants to do twin turbo front mouts and mount them in the fog light housings.
There is a really succesful jeep in florida going 9.60’s at over 145 mph in fu street trim at 5900 pounds i believe it is.
