Basic boltons and intercooler work fine with the stock tune but its going to limit your top speed because you cant let the engine rev out so you will need to repitch your prop to keep you under the...

“ Typically “ 83mm to 85mm add 100rpms and a little more speed.FX nozzles are 87mm and 150-200rpms but you dont go any faster or start slowing down a little.These are just some generalizations and...

I think you pretty much answered your own questions.A 16 degree pitch with a small nozzle is not moving as much water volume and can feel lazy on the bottom end.If you add a tail cone on that setup...

The skis I have are a 2011 and a 2016 both of which have alot more drag.You could have more motor spinning a larger prop to higher rpms but if the surface tension from the hull design is higher than...

30 lb, Cams, Ethanol, and Compression.Older hulls have alot more surface tension and need alot more motor to run your same kind of speeds.What I meant was actually the opposite of what I think you...

A ski going this speed in 80's air and Florida humidity is a solid 95 mph ski in dry winters air.We have an old style FX with alot more motor running similar speeds but it has to turn a 13/20 through...

I really think the extra speed is mainly in the hull design.Unlike previous FX's the V the new one is much shallower and there are lifting strakes next to the grate which keep the rear of the ski...

Rideplate mods are always a must do especially on big skis like the FX.Gets the nose up of the ski out of the water and atleast a 2mph speed increase without having to touch the motor at all.When you...

Thank you for sharing.Unfortunately we use to run similar short ram intakes many years ago and its not even close in comparison.Both of the setups I previously mentioned outperform it by 200 to 250...

Even if you keep a ski otherwise stock the single best mod you can do is a tune.Your going to pick up power everywhere adding timing and lifting the rev limiter its %100 worth it

The actual fuel system for E85 on a high powered ski is probably one of the biggest headaches.The stock charging system drops voltage at wide open and the stock battery is not designed to support a...

In my experience anything over 2 years begins to be borrowed time on an intercooler. Regardless of the vendor an aluminum core is going to rot out sooner than later if you use it in the salt.We have...

IMO its not a good bang for your buck meanwhile you still have enough octane with pump gas to make power other much easier ways.If done correctly you can easily spend over a grand between tuning...

Even when you show people there are always naysayers.If people dont know how to do something then it must not be possible.All I can say is to come to Florida and you will leave a believer.A 600 hp...

This boat is very impressive with a very simple setup OEM manifolds, cams, crankcase , and head.Just good tuning, big turbo, lots of wet nitrous , and some one brave enough to pilot the...

I read somewhere ( cant find it now ) of someone using it on a SVHO with decent results but the ski was only low 80's with stock wheel and low rpms.This power level seems to be the vast majority of...

When you have more mods and make more power the ski produces extra lift all on its own.The R&D plate is very fast but would bounce uncontrollably on faster skis with more mods which is why for alot...

Years ago I picked up one of those fancy ET 24psi wheel with a matching watercooled housing combos R&D use to sell.The front of the included wheel was huge atleast 1/4" bigger than stock but the...

Stock SVHO clutch 9500 to 10K rpm and 27 to 30 lbs for a good while now.They can last with a big wheel if you arent abusive and reaching for power all the time.Rough water riding, Throttle chops,...

To answer your question the twin impeller is no harder to turn and will work on the same setup as a single impeller if the overall impeller diameter is kept the same 155mm.The main difference is when...

No one seems to make the Web stuff live unless they run all there valvetrain components and blueprint them to the head.They tend to run too tight in the towers and wear into anything other than a...

IMO with the mods you already have 90 to 92 mph is possible with the right tuner and OEM supercharger wheel.There are at least half a dozen tuners in from South to Central Florida that can get that...

For recreational use you would not want to gut the hull insides.The removal of foam changes the handling and allows the nano to flex alot so if you hit anything at all out on the water you will...

Think again...Down in Florida atleast 24 to 32 psi charger wheels and 10,000 rpm on %100 stock engines with just retainers is recreational stuff.The problem will that kind of setup isnt the motor...
