Dave,
I would be very interested in reading that bulletin. You can fax me @ 714-5385461. My X dimension is standard production which I don't think would be considered high. After the install we will be doing a water pressure test and installing a guage to reflect that number as well as a fuel pressure guage.

Dave,
Received the fax- that was really fast service, thanks.
It's really confusing re: the valve,gasket question. Dustin emphasized that, with only 65-70 hours on my engine, that those items do not need to be redone. He also said that he has engines out there with 150-200 hours on them with the stock gaskets and valves and they are still running well. As I don't intend to race, and normally only cruise at 3500-4000, he said don't do it. A buzz to 5 grand periodicaly wouldn't hurt either.
Of course, I would never do that.

Hotlavey,
Yes, I enlongated the lower two holes on the bullet with a file. This was per Dustin's instructions. The upper holes were tapped and plugged with, I believe 1/16 NPT pipe plugs. I now have 20+ psi at wot.

Hotlavey,
I talked to Bob Teague at the Miami show about this and he felt 16psi was adequate. The low pickups on my stock LWP bravo gave me 30+ before the Whipple install. That's way too much according to several on this forum.

Detonation is brutal when it happens on any motor and I wouldn't expect to have any gasket hold up, but when you throw the air at it, we are not dealing with a stock setup. I am not an expert with this stuff, but when I pull a head off of a motor that has 250 hrs and the gaskets are deformed and falling apart, it's not hard to see why they don't last long after supercharging.
NordicHeat has a good point about the water pressure. Dustin told me that this is the most important thing, especially with stock heads to keep the hot air pockets from forming inside the heads. Hot spot in head = detonation = melted pistons.
hotlavey, add gauges to your list of $$$$$. I have a low water pickup on my imco lower unit and my water pressure is around 20psi, but when I had the stock bravo1 (5hours) I only had 5psi. You may have to install a offshore water pickup to get the water pressure you need. Your XZ might have a low water and side pickup, my friends does and his water pressure is just fine. I guess every setup is unique.

I'm having the Whipple installed the first week in April by a pro. It does include instruments and a trial run to check the fuel pressure, water pressure, timing, etc.
After all the help from this forum I decided that a professional install would be the safest way to go. There is so much that needs to be tested by someone familar with this install I felt I better have them do it as they will have the expertise.
