S-10 Update

Hey guys,

For those who have asked and been watching me fumbling through my project I thought I would give an update.

I got the transmission leak fixed and got to go out for some more tuning/playing this morning. The engine is running really strong and it accidentally saw 15psi and 5500RPM today........pretty fun ride for a second. What I am finding is that the turbo and piping design are really working well to make boost. With just slight load on the engine the turbo will make 5psi. Today, I finally got the nerve to push it to about 3/4 throttle from the 5psi point. The boost gauge shot to 10psi, nose rose up, and we were off. Hit second gear 1/2 a second later and boost shot to 15psi in a split second as the engine hit 5500RPM about as fast. From this point I had to get out of it since boost was obviously out of control since the wastegate was set at 8psi.......and at less than wide open throttle.

The short power run was a rush, but it became evident that I need to make some changes. I took it home and begain to tear it down. I have a 50mm wastgate on the way to replace the 38mm and I am going to change the piping of the gate up to better regulate boost.

I also am going to have to get the entire exhaust system ceramic coated. I am melting wire loom everywhere from exhaust heat. So it looks like it will be yet another month or two untill I get to run down the 1320, but the truck appears to be getting the bugs worked out.
