    88 MPH in the House!! Ben's Performance Plus is ready for you.

    Welcome guys, to my new business adventure.
    Ben's Performance Plus
    Located in Jackson Mississippi
    I have decided to start doing in-house performance
    mods to GPR's and other brand of ski's. My main
    focus will be on the GPR. I have been working on jetski's
    since 1992. I have worked on all brands, and have owned most
    of the performance models since I started in 1992. I
    remember back in 1993 when I was running low 50's on my 93 XP.
    Then I stepped up in 94 and went with Yamaha Raider 701. Before
    I sold that ski it was breaking 60 mph, with some basic carb
    mods and porting. In 1995 I got the bad boy 1100 Raider that
    ran 58 mph out of the box. After two years we were looking at
    a 65 mph boat. We stepped up to the 97 GP1200 shorty after, it
    was a new hull, and it didn't live up to it's hype. I sold it
    later that year, it was no faster than my 1100 Raider, and ran around
    57 mph out of the box. I decided to go back over to the Seadoo
    side, my focus was on the 96 XP and 97 SPX. After building a VE
    920 big bore, we were seeing 70 mph on a twin 2 stroke motor.
    In between these projects I also worked on the Kaw. ZXI and
    the Polaris SL 1050 motors. After having back surgey I gave up
    ski's for almost 2 years. I then pickup me a XPL, where I spent
    a few years on that project. I sold it last year, after running
    speeds as high as 74 mph. The holeshot and acceleration on the
    1050 motor could run with almost anything, the boat could not run
    with the current 80 mph boats. Thats when I decided to go back
    to the dark side, picking up a blown GPR less than 10 months ago.
    My goal was to someday have a 80 mph boat. Little did I know how
    easy it was to make these boats fly, using a almost stock 1200
    motor I was quickly running 77 mph in a matter of weeks, I was
    shocked that I had been working like a dog to make a 2 cylinder
    Seadoo just break 70 mph and now could do it with just a basic
    bolt on package. I'm now at the magic 88 mph zone. I'm now at
    the 10 month stage and knocking on the 90 mph door. I'm happy
    that I'm doing it with a 1300 motor with mostly oem parts, and
    the ski is setup with my porting, timing curve, and my custom
    handling package that I have been testing for the past few
    months. The ski is still running stock oem carbs with oil
    injection. The ski is ready for a larger prop, but I will also
    be using a larger set of carbs and a larger bore motor in the
    future. With these mods this will allow me to compete with the
    fastest ski's in the world. I will be on equal ground and
    have equal size motor's that are currently being ran by my
    friend's. Here are some of my in-house packages that will be
    available to my customers. If you are interested please contact
    me at [email protected] or just P.M. from this board. I'm currently
    working on two 1400cc motors and two EFI boats, and have interest
    in a few more later this year. My weather here is the south normally
    lets me work and test all year round. This will be a big help for
    the people up north. Prices will vary, depending on your boat and
    current setup.
    Thank you very much for your time and I hope I can make you
    a happy GPR owner. Ben Herman
    The Hermanator Package, It will consist of three different
    packages for different HP boats. Not all ski require the same
    handling setup. Thats why I like to do everything in house, not
    just sell parts but to give your boat my personal touch. Stage one
    is for boats that run up to 75 mph, then Stage 2 is good for
    76 to 81 mph. Then there is a different setup for boats that are
    running 83 mph and above. One thing I have learned, is the faster
    you go, the less angle plate you need. There is no need for high
    angle plates and locked down ski's. Why give away speed? The
    handling on the GPR will always be there. A very simple change
    can always be performed for rough water handling, its as simple
    as changing your 800 grate for your 1200 grate.
    The one thing I have tested very heavy on is solving the bucking
    issue on the GPR. There are two problems, one is the 1200 grate
    over stuffing the pump, then there is the high speed runs made
    on the 800 grate, where you actually buck out of the water due
    to the lift of the ski. With the high lift it will cause the ski
    to loose contact with the water. I have attached a video of this
    occuring at 87 mph. This problem can occur as slow as 74 mph. I
    have found many items and changes to help this problem. A small
    change of angle on the ride plate, repositioning the pump shoe,
    or the intake grate, sponsons, and other tweaking can stop or help
    this problem. Just remember the faster you go, its harder to control
    but I'm having good luck up to 88 mph with minimum speed loss. If
    desired, those speeds can be reach without bucking or trim tabs.
    I feel like this is going to be one of the most important things
    you will get from my setups. To learn about your ski, and to
    understand your boat more. While some people call there customers
    and tell them there boat is ready, and off they go without
    knowing one thing about there boat, other than it does XXX mph.
    There will be no one off parts used, all parts will be available
    through a number of sources. Never depend on one person, they could
    be here one day and gone the next. Learn your boat. Learn how to
    be a good tunner. Its part of my Plus Package.
    All of my plates are done be Jim's peformance shop to my specs.
    Again some will be different based on setup, year of boat. And fined
    tuned by me on the water. No addition money is needed to setup
    a boat with the top package. This is supplied by me at no addition
    charge for in-house boats.
    Other services available, custom timing curves written by myself.
    These are curves that I design through Advent, they are for my setups
    only and label by me. If you do come across this info, I don't recommend
    you using the info, it could damage your setup, there are other things
    required that you have no way of knowing. What porting, squish clearence,
    octane requirement will work and most important my custom water
    routing for triple pipe and single pipe setups.
    Customs pitch impellers and pump combos.
    Limited, superstock and big bores available.
    Triple or singles.
    VF3 reeds or anything else needed.
    Upgrade kits, pump shoe repair, sealing, updated brackets on pump
    shoe, ride plate.
    Complete motor rebuilds, even if you have just a stock ski and
    don't want to wait all summer for your dealer to repair.
    You name it, we can do it.
    This service is not about making money, its about doing something
    that I enjoy, most of the money will just be put back into my ski
    to test and make it go faster. I'm also adding a second boat to my
    garage and it will be a single pipe boat. With your help we can
    continue to make the GPR even faster.
    Below are some video's of my ski. If you notice in the second
    video the ski had a buck at 87 mph. This was because of the loose
    bolts in the intake grate moving out of its set position. At these
    high speeds it is required to do regular maintance on your boat
    for safety. Checking bolts in your grate, ride plate, and checking
    for cracks in grates, ride plates and support brackets will be
    required for any boat running above 80 mph. Lets prevent a problem
    before it happens. All of my current high speed passes have been
    setting on the seat or on the back section of the seat. We all
    know that we can pick up additon 1 plus mph doing the old superman
    trick, but at these speed I recommend safety first. These runs
    were made in smooth water, but a prefer a very slight wind wripple
    for best top end speeds on a GPR. My testing has shown a loss of
    .5 to 1 mph on pure glass. Enjoy the video's and ride safe. The
    goal has always been 0 to 90 mph, in less than a year. Ben

    Those who are interested in Ben working on their ski's can rest asure that he will do a great job in your ski's. I have been dealing with Ben for a year now and the enthusiasm and time that he has put on his Junk Yard Motor triple pipe GPR has paid off.

    I have been sending Ben multiple parts that I had in my bench for testing but have not been able to including modified carburators, modified rideplates, different V-Force cages, props, modified intake grates and after testing different setups he has selected the best of the best. Ben will not try to corner the market by doing all of the work himself, he will approach the appropiate people to obtain the right components and porting jobs and make it happen. I got on the works a modified Stinger III pipe to test and a different water injection setup for that brutal midrange acceleration that Ben will have available if everything goes according to plan.

    Many have only seen Ben in the GPR picture for just a few months but Ben's expertise comes way back, way back before any forum were created. Prior to Ben joining the GPR Klan, I read many post were some Doo business felt threataned by Bens ability to make them XPL's fly, I guess they did have something to worry about.

    As a matter of fact I was warned that if Ben Herman ever got on a GPR we were going to have our hands full trying to beat him.

    Its time to get back in the saddle and improve the 1300R platform some more!!!!!

    Kawi 15F 400+ HP hitting the straights at over 90mph. On display with others in my shop. You guys should have been around the radar gun in Nashville when we took it out for practice.

    Hey Billy,
    I will try to give you a ring. I will need some gas soon. Are you interested in running the 15F down the channel by Tommy's Trading Post? I would
    like to see how my boat stacks up with yours on acceleration and top end. I should be out tommorrow morning. Ben
