Well, stuck it on this morning. Probably 1.5 hours total as there are some brackets and stuff that need to be modded. Mine was shipped with a 3.25" upper and I have a 6# lower on there from the Apten blower. Was expecting about 15-16 psi according to KB; getting 18 when I pulled my foot out of it. I am running 91 octane and alcohol injection (timing at 19 degrees). No pinging but too much boost for a stock longblock. Will put on my 4# later and re-test. May need to buy a 3.5" upper, which is what I was told the unit ships with (not mine).

Thing pulls like crazy up top, but feels pretty much like the Apten in the lower ranges. Not as loud as the Apten either. I will be doing some dyno pulls and will post the direct graphs versus the Apten pulls I made recently when I can get the exact same boost (16 lbs.)

Six pound lower 9.0" and a 3.5" upper I see 14-15 pounds of boost, 16 pounds when it grabs a shift.

 

SWEET

I would love to see the comparison
