BBB Big Bore Boss 322
I didn't like the fuel trim swings associated with the stock draw through set up on my Paxton. The solution was to go blow through for more accurate maf function.
First the coolant tank had to be moved to allow enough room for the discharge tube. I went with a Canton tank.
Here's the 3" tube with a hpx maf. Had a local guy weld the flange for this and the mondo, cost $35.
The mondo blows alot of air at idle. Right now I'm digging the sound but it could get old fast. I may route a 2" hose with an air filter to quiet it down some.
Put together a replica "Power pipe". It's been well documented on this forum how to do it. Bigray, Lightblade and Greg Hazellet come to mind off hand. I'm sure there are others too. Having this forum for research is invaluable.
All I had to do was get a 3.5" to 4" 90 degree reducing elbow. Cut about 1" off of the 3.5" side and connect it to a 4" 45 degree elbow. Reused the air filter.
The last detail was what to do with the passenger side pcv line. I put a breather on the hose and stuck it down here until I figure out what I want to do with the whole pcv system.
I used the ba5000 value file for the hpx meter. It uses the same values as supplied by pmas. The test drive revealed it's real close. Fuel trims are good and I'm not touching the maf xfer until I get it wot on a dyno. I'll bet there won't be any need to adjust.
