Yep! Planning to run 3 prefilters while daily driving and doing just the guard for the dyno pulls.

Hoping to have dyno results this month.

Tightened the belt last night and did a pull this morning, making a solid 14.5psi.

There still seems to be belt slip at 6800 rpm, which causes the manifold pressure to flat line. The 'projection' I referred to earlier refers to extending the boost curve out assuming I had no belt slip, the kit could potentially hit 16psi.

I had discussed this with Aaron this morning, we are worried trying to chase that last couple psi may result in undue wear on the belt/sc bearings.

So I may play it safe and be happy with 14.5psi.

UPDATE: Looks like my theory is correct. I think this kit can hit 16ib of boost when running just the turbo guard. I decided to bite the bullet and personally hit 15.2ib while tightening the belt down even further.

SHOULD you do this is another question. Personally I don't want to leave the belt this tight for fear of severely reduced belt life, but interesting to see what this thing is capable of!

NOTE the turbulence in the higher RPM range I think is due to VVEL and VTC becoming active.
