    Default turbo systems.

    I am new to this forum. So first off, hello everyone.

    Now business... I have a Formula powerboat in which I am thinking about putting a turbo system on. Anybody out there that makes a complete kit?

    Default Race Aero Turbo System

    Complete from the intake manifold to the exhaust manifolds, and everything in between. Not new, but a proven 800+ HP system.

    For a new system, contact Brummett Marine in Pasadena. I believe that they have all the race aero/Gentry hardware.

    Welcome to the boards!

    My suggestion to you would be to research and read everything you can before spending the money. Find out exactly what you want before laying out a bunch of coin on something then finding something better. I started where you are, I looked for a complete system but found nothing I liked so I made my own. Started with two t-3's on a SBC/mechanical fuel injection and now run two t-3's and two t-4's. It runs so good I now need to spend the bucks on a good bottom end and heads . . . . I killed the stockie I started with this year but hey, it was fun while it lasted Now it's time to step it up

    That looks like a one off kit with a precision air to water IC. Looks like a pair GT47-88's as well. That kit complete with headers, turbos, waste gates, bov, clamps and flanges, tubing, Fuel Injection system with a tune is an easy 10K with out all the engine mods......

    How much do you want to spend? What are your Hp goals? Let me know your hp goals, cubic inch, how many rpm you want to turn it and I will do my best to help you along!!

    Take care,

    Travis

    It would be a huge performance increase to remove the two small turbos and only run the two larger ones. The small ones are only serving to bypass exhaust gas pressure that is needed to feed the main ones.
    A local guy with a 373 sbc and one turbo / efi made 1050 hp on the dyno at 28# boost. He had it in a pro street truck.

    This boat was done by turbo technology in wa. I am usinug the pics for reference.

    I am looking for around 800hp on low boost, and 1000hp turned up a little. Looking at a pair of 61mm with 76 trim hot side. turbos.
    Will be on a 25' Formula with a 502.

    I am runing a pair of Borg Warner S400's and would reccomend them for your application as well. They have a 75mm wheel and a T6 turbine. I would not use a T4 base turbine on a 502, to much Back pressure. The advantage to using Biger turbos is big hp on a pump gas tune due to less heat. tHE bw S400 turbos go for around $600 each and will make 1,000 on pump gas with a nice air to water IC and 12-14lbs of boost.

    In a closed engine compartment you will also need water jacketed exhaust wich is big $$$$$. Here comes whitley has a pair on his deck boat and I think they are around $4,500 from CMI.

    I love talking turbos first thing in the morning.

    That is my plan, actually I set the system up to blank off the exhaust in any combo I want (two big/two small/one big one small/none) and see how it runs, but the old SBC never lasted that long. I will say, when it ran good, it hauled ass, especially with four. A big help has been video taping each run, the camara not looking forward but looking back at the boat from the bow . . . I have a dial-a-jet and some other stuff I can adjust and you can really see the differences on the playbacks. A new plant is in the works as I write this. I also set it up mocked up for our LSR car (intercooler, etc.) and will be making the changes to set it up for the boat and incorporate many things I have learned the last 2 years and pull stuff off I don't need. I did the twin's year before last, the quads last year and got it dialed, this year but have struggled with the engine (I thunk it finally realized what I was doing to it) . . . . this being my first flat, actually my first hot rod boat, the last couple years have been a learning experience filled with good and bad advice, lots of good times and many many new friends So I'll keep playing with Shiver Shot, the LSR car I have since sold, it had historical value as an old Bonneville Car from the 1970's and I could not get myself to cut it up. I sold it to a current record holder and it is now being restored in Salt Lake City. I will still eventually do a LSR deal, but it will be multi-engine or turbine powered lakester or streamliner. I just need to win the lotto . . . . . .

    not trying to thread jack, but what turbo's should i be looking at if i wanted to build a 1000hp 406 with say 25-30lbs of boost? i wanna do a single blow thru set-up, and i'm gonna build my own water to air i.c. set-up, it should do a good job bringing the intake temp down. be even nicer to just run big enough turbos and not have to i.c. , but i don't want any turbo lag.

    I get turbo / Hi tech performance mag and its amazing the size of turbos their putting on the small import car motors now. I saw a feature on a 6 cyl Supra engine ( 3 liter ) with two turbos about the size of the ones I have on my 540. They made 1500 hp with it. The turbos are so big that it takes ball bearings to help them spool up.
    The turbos that came on the old Banks and Gentry setups are puny by comparison and are way too small on a big block IMO.

    On a SBC I would go with something with a 94 mm or 102 mm compressor wheel at least. The two TV77 Garretts I run have 94 mm wheels.

    How about a single Garrett GT47 or a Master Power GT45 ?
    You can buy three Master Power turbos for the price of one Garrett but Garretts have the most years of proven performance.

    I have'nt had any concerns with lag at all with EFI. I was told by a guru that lag is a function of the fuel system more than the turbo. Draw through carb setups are the worst for lag.
