Very true,

When you mix dual VVT with GDI you can do a lot of fun things esp with regard to anti-det and anti-surge.

Seems to post fine Joe.

The 5.9L Cummins question, just found some old dyno sheets, check the dates. Also, I was wrong about the 10 deg taper it was 2 deg - I see it on notes at top of the sheet - wow this brings back many days of inhaleing black smoke!!!!

Last thing for tonight. Here is our truck for the 7.3L Navistar race boat. Note the cut away Navistar 7.3L for display, it was able to rotate if we wanted it to, this was cool - people would gather to see inside an engine! The boat was a Maelstrom 23 built as a race boat, I believe the only one?

Habana Joe, I see you tested in a 34 Super Hawaii. That's what I have. Did you have the engines in a staggered setup like the standard gas setup was? What kind of speeds did you get?

Thanks for sharing your knowledge.

Oh yes, my old company and the 34', wow what a boat!!!!

The engines were side by side with Arenson drives, direct drive 1:1 no reduction. At 3,000 you ran 76 mph and cruised at 55-60 mph all day every day. They were 380 hp Cummins B's.

I took Craig Barrie & Bud for a ride at the Ft Lauderdale show in 1990 and they could not believe it, it was unstoppable. Our exhaust were underwater when ideling or running slow so it was very quite. When it poped up and the exhuast roared (no mufflers) the two of them thought something exploded!!!!

I bulit a test 34' and 40' for myself. The 34 was kept up here in NJ at the diesel shop and I had 2 guys that tested it everyday. They would leave Morgan creek and run around Staten Island for 6 hrs a day, 5 days a week at 55 mph steady. On nice days we would take the boat to AC and back, sometimes Cape May and back just to not look at the same scenes.

Let me find a picture of it, I'll post it ASAP

Here's the 34' and my old Maelstrom at the World's in '89. It was very rough for little boat like that, real rough. I believe it was Kevin Brown that stuffed that day with his Skater, well you know what happened. John A from Spirit of America broke his back. These were ocean races!!!
