What I have done to my 250.(70.7 mph)
I have the Wedge.
I have the Riva Exhaust Bypass
I have the Rogue Jet Intake Spacer
I have the Ram Air Mod
I adjusted the BOV
I have the R&D Fuel Extender
I have the oil level right
I have made a few other openings in the Hull to let in freash air or hot air out
I have a HD* Custom Intake (a work still in progress)
I have a Jims Performance Cut Stock Ride Plate
I modified the intake grate by narrowing the intake grate bars, and the round connectors.
I have also reseald the intake grate.
I cleaned the gullet to where its smooth on the inside, no ecxess silicone.
I have a Groco Strainer on the Intercooler intake water line

IMO I think that the intake and the exhaust need to be done together, for full benefit.And I like the way it sounds, I put the Riva Exhaust and a Power filter on my 15f also, I think it sounds better than the Ultra.
The adjustments to the BOV was no help at all, the boost gauge read the same with all adjustments, not to say it wouldnt benefit someones whos was leaking.
I know I lost a few mph from March(70.6 down to 68.6 mph) till the other day, I did the intake and the Ram air mod at the same time as I did the extra openings and Groco filter, so its hard to say what did what, Im just looking to run 75 mph in the smooth, and 70 mph in the rough.

what is the Rogue Jet Intake Spacer and where did you buy it?
Also where are the extra openings etc?
Did you do the same Ram air setup as what skip described on his blog?
Thanks for sharing.

Roguejets.net, its a barrier between the intake and the block, supposed to keep the intake 20*degrees cooler that the engine, by putting a spacer there,they say for every 10* of lower temp = 1 hp.

I have the wedge and bolts, got them with the ski but have not installed yet. I spent about 2 hours removing 5 extra pounds of silicone from the bottom of the hull. Tightened all hoses. Can I buy this stuff from GH? I would kill to have this thing go 75 on glass.
