Re: El Caphoon coming soon...
Got it running last week, took it off Jack stands sunday and took it for a test run, from a small 2 psi launch, hazed the tires, first and second then overboost showed up. Realized that stock boost control configured for a stock turbo wont control the 14.6 psi wastegate actuator on the 20g... plumbed the wastegate feed directly to the turbo, then i Repaired the missing ground for the mat sensor, made another street pass... wow.. this older country road i live on won't hold it. I didn't know if the free flowing exhaust was the overboost problem, so by passing the stock control would limit the output to what the wastegate was loaded for. I'll be taking the truck to Phenix Motorsports park to make a few Datamaster passes down the 1/8th mile. I have to insulate the a2a pipe that passes over the turbo area because aluminum pipe absorbs heat pretty quick. I have the turbo, down pipe and manifold insulated pretty good, but the inlet pipe still gets warm. Once i get the truck running great on the stock 30lb. injectors, I'm going to get mike to burn me a chip for 36lb. injectors. I'll post the times on here when i make the passes, just remember i have about a 500lb advantage in the weight department,but a lack of all wheel drive in the traction department, but these g bodies can be made to work very easy on the track. Again, thanks to those that have posted all the information on this board that helped me make this happen, along with the rest of the people that helpedme with the parts.
