Recently dumped my 80mm stock MAF with Diablo MAFIA and switched to the BA3000 blow through setup.
Easy switch mechanically.....Problems began with retune.
The BA3000 housing is 4" while my piping after the MAF is 3.5 inches with my P1SC. NO problem bought a 4" to 3.5" reducing coupling.
Car went for retune.....My tuner called me to say the MAF housing was continually separating on the 4" side at 3500 RPM. The 3.5 inch coupling and tubing were fine.
Installed T-Bolt clamps thinking the change in air from 4" narrowed to 3.5" was blowing the piping apart? Held for a while.....
Problem now is despite T-Bolts....I will periodically get the 4" housing separating from the 4" coupling despite the T-Bolts. My theory is as the piping heats up and the subsequent heating and cooling causes the housing and coupling to wiggle apart. Will happen in the morning without any airflow as well..
I tried silicon but didn't help. The damn SCT 4" housing has only about 1" for the coupling to grab and no "lip" milled into to prevent this very thing from happening??...
The BA 3000 will not fit in my stock 80mm housing that never separated under the same boost levels.....Solutions?
1.) Switch to an 03/04 Cobra housing/MAF but I am unsure if that housing is 3.5 inch and would I need a MAFIA again?
2.) Tack(sp?) weld the 4" housing to the 3.5 inch piping and simply use the coupling I have?
3.) Buy a smaller SCT BA(2600, 2800) MAF? And does this have a smaller 3.5 inch housing?
I am leaning towards the welding? ANY other suggestions that won't cost hundreds of dollars?
MAF has maybe 500 miles on it? Thanks.....
