Finally blowing some air!! Have the intercooler back in and the plumbing to the cooler done. Ran it around the block and all of the belts seem to running true. It is amazing what the intercooler does. Put you hand on the pipes coming out of the blower and it is HOT. Grab the outlet side pipes and its like they are refrigerated. Things left to do. Finish plumbing to the carb, set up the boost/vacuum lines for the regulator and the boost retard. Plumb the bypass back to the intake side of the blower. Light at the end of the tunnel..... hope it's not a train!
Not a Buick pump, it is a Sweet pump from a circle track car. I am using stock pulleys and had an adaptro made to use the blower pulley from an LT1 procharger setup. I worked really hard to get the blower low and have a short belt. The belt is only 55 inches. I am sure you could adapt a pump from an LT1 Camaro and not have to use AN lines. You would have to get a belt pulley for it. I may try to get a smaller pulley for the power steering pump so it works a little better at low rpms.
It is all mine. The only things from ATI are the blower, belt tensioner, and pulleys. I made about 10 prototypes with 1/2 inch fiberboard then had a machine shop cut the aluminium. I can see more improvements that could be made in the brackets but this will do for now. The belts run true and there is no flex so I am pretty happy with the basic design.
Blowing air to the carb now. All that is left to do is plumb in the bypass valve and it will be making boost.
doug your carb will be on the dyno next week. dropping the engine off friday and will be setting up intercooler and fuel system early in the week hope to run wensday. go 350 go
Hey Doug excellent progress! Would you mind sharing the cost to build this bad boy? Can't wait to see the dyno tests. Scott
scott I didn't mean to miss lead you the engine going to the dyno is my sons 370 inch buick small block he built. we are borrowing the carb from doug he got it from us and I wanted to use it for my sons car and we thought it would be a good test. Just a little 650 quick fuel blow thru unit it will support 700-800 HP so it should be a good test if we turn it up on the dyno. we won't be near that with this motor but it will be a good start for a 17 year old.
Scott Are you nuts!!! POST COST! My wife can read! :laugh: :laugh: All depends on what you have. Here are some real rough guesses on what I have spent. 455 mild build 440 HP-starting point Fuel system- $800 Must be boost referenced and do not skimp here Ignition- $500 I put together a system with boost retard Intercooler -$500 The intercooler is cheap it all the other stuff that adds up Carb-$600 QuickFuel from Bobb Cometic gaskets- $150 Lowers compression from Bobb Poston pan-$500 Looking for a little help for the bottom end Misc -$1000 material, machining shop cost, welding Procharger D-1 from a Camaro- Free You can drop $10K in a heartbeat on this kind of project. It is all of the stuff that goes with the boost. I am trying to be proactive and anticipate problems. Next up is a new driveshaft and rebuilding the tranny for the anticipated HP. Oh... how about new axles and c-clip eliminators?
