I like the high tech way they screwed the rubber hose to the TB. No need for a billet adapter there! You better secure that IC to TB hose/tube if it's not already. That sh*t will be flopping all over the place!

A prop change should help. My H2X runs 79 on the GPS with 4lbs of boost spinning a 4 blade stock Bravo 26, full tank of gas and 2 peeps.

I don't know but starting with 320 hp if I'm right, I'd say plus 100 hp with blower so 420 total...

It is a 468 with a little B&M 250 that was built by TBS. I put a semi-labbed 28p 4-blade on in the heat of the summer (95+ degrees) and it still ran 78, so now that it is cooling off some I hope to be north of 80mph this weekend.

How much boost are you running. I had a very similar set up in a 22 Stingray that worked out great. Nice looking motor by the way.
