Sloppy Mechanics

turbo silverado results today!

well i got the 75lb injectors today... but they are the wrong size, they are like 1/4 inch too short, fucking sucks. yeah well i guess i ahve a set for the g8 now...

added a boost gauge to the truck and decided to take it to the dyno and see what the stock injectors can do...

now as all projects go, specially 4 day turbo truck projects, there were some hiccups, we were only hitting 2psi on the lowest spring in the gate. turns out its just that weak, it comes with 3 springs, the weakest with the pre-load turned all teh way down was only hitting 2psi. after checking everything for boost leaks i pre-loaded it more and it hit 3psi. then with a mbc turned up it hit 6max, now we were rolling...

threw in the next step spring, hits 4-5psi

cranked up we hit 9psi for now running close to the end of the stock injectors.

we were running the truck in 2nd gear on the dyno because it does 99mph in 2nd gear, the only thing that sucks is the dyno roller weighs alot less than teh truck does, so it spools later, way later than the truck does on the street, so the whole dyno chart its basically spooling, you can see with the power lines...

other than that we will do some street driving tomorrow, it feels amazing on the street.

base stock pull vs base turbo tune for now on 9psi
