I know yours has run great for some time. Best guess where it was 9n hp before rebuild? I know 400 chp is the goal just wondering what the step up might be?
What did the builder say about breaking the bolt OFF?
that all sucksvexcept playing with the Bridgeport!
BrianN enjoys rebuilding the suby engines ..... just ask him
Your def having a challenging time like I have been.
Outfront said my old engine S/B 320hp. Going from 10lbs to 15lbs boost, I have heard that getting into the teens on boost will really wake up a subi. I ran the setup for 12 years. I wanted to go up to 17 or 18lbs (just to have bragging rights over Mike
) but John wanted me to have a boost controller if I was going over 15lbs, I didn't want to mess with one.
I didn't even talk to the builder, I already had the heads installed before I realized the bolt was broke. The bolt broke off about 3/8" down into the hole, so I made a bushing on the lathe to fit the hole then used a left handed drill bit. My wife said "They make drill bits for left handed people?"
I was nice in my reply.
I am only going to run 10lbs boost this next trip as I don't have time to get it on a dyno. But it will be cool to see the difference in the newer style turbo and how it spools up/
I bought the bridgeport from Jerry and added a DRO to it. Still need to add the 3rd axis, just haven't had time.
