Carb or timing for sure. You should put out DOUBLE those numbers.

is it actually building boost at all, its not by the sounds of it!

even only 5# of boost should pick up the HP by 75-100HP

[WALT]

It starts backfiring Stan ploted it on a chart thinks it will only put out about 6 lbs with this impeller.

Just got a phone call from Don owner of Motor Machine ,he told me I cant work on my car any more,he taped a hole on the super charger outlet ,installed a gauge found a big pressure drop to the carburtor.Using a remote camera found a rag stuffed up in the intercooler,dam I hope he's not pulling my leg {i've been saying that maybe there's maybe a rag is in there jokeing } All I can say what a shop to have in your town .I will let you know the rest of the storry as Paul Harvy would say later .

No doubt that engine should be screaming

[WALT]

Well we got that rag out ,it was mine? Anyway that did not make that much in flow difference. My intercooler is a tube & fin type. Found out a bar/plate flows better? Mine says it flows 750 cfm, the bar/plate shows 1250 cfm ,I ordered one ching ching again.Looking at them thay look like twins. Walt
