I am using one of the Dawes grainger valves to control boost
and the wastegate has been shimmed to prevent boost leak.
A hi-flo cat converter finishes it off... Show more and there is no muffler.
Small update with a couple of new pics
A Walboro 255 litre fuel pump was just installed to replace
the stock pump. With the additional fuel, I decided to go to 25lbs boost.
Update: The shims are gone because of the new blow-off valve.
Now the car will roast the tires in 1st and 2nd.
