Evening.

So it turned out to be a faulty Cold Start Injector. Car made 189bhp & 222lbft at 16psi, and is now fuelling and timed perfect. Despite blowing the top radiator hose off 500 yards from the dyno, and the oil slick it left behind (4 attempts @ sump gasket and counting.

I now need to replace my radiator as the top outlet has crumbled to nothing. Any recommendations? Alloy or std replacement?
