TD42 fuel screw adjustment, what temps?

Post by adriand82 »

Hi lads, have just installed a turbo kit on the GQ. I am wondering what exhaust gas temperatures you guys are getting once you have changed the adjuster on the pump? Also, how far have you turned the screw inwards to maintain a good balance? I have mine turned in a half of a turn in total. Cheers.

i'd only be tuning the fuel and boost together with a pressure gauge and a digital pyrometer under various load ie. dyno, to ensure that u dont go too hot. half a turn is pretty extreame adjustment on the injector pump. i'd be careful or else u might get some rings welding to the liners. . .
