Ohhhhh , Fuel congesion !! That helps huh ! How user friendly is your injection system ? I hear of a lot of people haveing problems with it on big motors like that trying to map it out right .
300 hours sounds nice ! I second C_sprays quesion , Do you have cooling on the turbos to keep engine compartments cool ,or wrap to hold it in . Thanks for the info . Good luck with it .

Any chance of a couple pictures ?? ,JOE

i've found your deffinetely better with a water cooled turbo two reasons one you don't need to run cool down idle time, two your in the water so you have an endless supply of cool water.
superchargers run more low end torque while turbos run more high rpm horsepower. "generely" but as check300 said newer turbos with ball bearing setups and lightwieght impellers spool up at alot lower rpms than the older ones. The biggest cause of turbo lag is superheated air that can't atomize the fuel properly but with ample suply of cold water for intercooler turbo is deffinetly the more efficient forced induction if the two. my $.02

Programming the fuel map does take a little time. Most of it was done on the dyno with the final trimming done on the water. We do use a heat shield on the turbos but it is cooled with air not water. The air intake charge is cooled with an intercooler.

check300: air to air, or water intercooler? I know in big aftermarket turbo's its hard to find water cooled but the operating temp difference makes an unbelievable difference in longevity of the turbo. due to being an air cooled you have to run a cool down idle time dont you. with the water in the turbo housing it dissapates the heat so it doesn't need a cool down after a hard run.

I am sensitive to cool down time. The motor is a dry sump motor and holds 18 qts of oil. The turbos have plenty of lubrication and that also helps with longevity. That was not my red Checkmate...mine is all white and it's a 30'.

You guys are all awesome and I thank you for the interesting information on this subject.

quick question? What do you think about these calculation figures?

40ft skater 8000-9000lbs / 1500ftlbs torque / (?) arnesen drive / 170mph?

Not sure of the speeds but you are light on your weight estimate. David Scott's 36 Skater is heavier than 9000lbs. Course he runs over 190mph!

I saw a 2000 Mustang with a turbocharged 398" small block running 30# of boost that made 1800HP.
