Paul....Yes it's a blow thru system.
The turbo fits below the round rear tin to the left of the oil pump. All four tubes of the A-1 exhaust converge down below along with the gate valve. One tube ascends thru the rear tin about where the left heater hose went thru and then up to the top of the carb. The heater hose hole on the right side of the tin is where the inlet tube comes up from the turbo to take in air. pretty clean install ! I think he says he's setting them up for 7to8 pounds of boost. Believe the carb is "weber style" two bbl progressive set up and jetted properly to be used with a blow thru turbo system. Boost pressure is adjustable of course.
Chico has two systems. One for a type 1 and another for a type 2. I'll get some photos this week when I go over to see him. I know he will have some photos on his web too.
Stan....I'm sorry you were disappointed with Chico's work or products. In all fairness, and I'm glad you mentioned your experience. I certainly would question the validity of someones reputation if it was always perfect or "wonderful". Of course your input is valuable no matter what the topic. You certainly have earned that reputation on here.
Oh...A little note ! I stopped by VMC today and spoke to Greg. He told me that we needed to meet in two weeks to finalize my Spyder build. He said it will take a month but that's optimistic I think. Anyway I will be in Mexico the day after Thanks giving so hopefully we can work out any build obstacles or directions before I leave. Sooo, I'm pretty amped up tonight.............Bruce
