Where did all the 66e conversions go?

would you guys then recommned Stoker or BB over 800 platform ??

Without question! There are many PROVEN 62T based stroker and BB platforms out there. Parts are common (relatively), knowledge is abundant both from many builders in the biz and also riders who built their own.

Simply put, there is no "set recipe", if you will, for a 66e platform. You have to custom build them as you go, relying on your own time, skill & craftsmanship + WDK :rolleyes:, and the know how of a select few out there if you can find them. Better have alot of time, patience (and money helps too)

again, just my opinion on the subject...

We have ours dialed in and it runs great. Of course were talking lots of $$$ to make it that way. As far as a stock 66e kicking out the power you want, ehh, we had one. Our ported 760's would smoke it. To actually get the result you want out of the 66e motor, you need to big bore it, run total loss, get custom head/domes, new intakes, all the parts Jeff makes. I would really like to see Tim get his finished and see how one runs on a B-pipe. We are going to build a new pipe when we transfer the 992 over to a roundy this year, not sure how its going to turn out but what the hell. In case someone hasn't seen the original build (which I doubt) here's the link - http://www.x-h2o.com/threads/9370

To answer the original question (My opinion)... I think you don't hear much about these conversions because there are VERY FEW that actually are running and even fewer that are running WELL. Those that jumped on the bandwagon thinking it was the way to go either never got it complete due to lack of parts or frustration in getting it all together and running.

Lets face it there is NO good exhaust solution to date for this setup. Sure WDK has their wet and dry pipes if you can get your hands on one and then will it hold together once you do get it? The manifold that Demon & Tom21 were working on might have been the answer, but it is dead in the water...

Performance... 66e's are HEAVY, both in overall weight and in flywheel/crankshaft weight. So they do not spool up quick like a 62t based platform... Unless of course you step up to total loss and a specially lightened crank - but who's doing that on a "budget"

All this being said, I know there are a select few people out there that have put the time and $$$ into these to make them work well (such as superramjet & WDK/Ski Clinic) and they can be incredible. I just dont think they are any sort of inexpensive big-power solution for the average rider (and budget).

If there are truly a bunch of these out there running well... please prove me wrong and post in this thread... let's see pics and tell us what pipe & ignition you're running, and how does it run?

(I don't think we'll see many responses)

I lost a lot of ride time last year because of that motor. It's nice but I'm more of a rider than a builder. I putting a 61x together to ride this year.

I bet for the cost of a 66e conversion you could add an X-Scream cylinder to your motor and be way ahead.

Never liked the 66e motor. Them suckers shake like a clapped out Harley.

not sure who it was but I saw an exhaust manifold- cast - that was made for the b pipe. looks like what we had intended to do. my next best step was for aluminum tubing to replace the crappy stainless. No time-no money(Tims money that is:smile:)

I don't think the conversion is all that hard, we only had making a manifold left to get all of our answers about is it worth it or not. Tim's boat made a lot of torque type power. Had we gotten some time with the carb setups we planned who knows if we could have gotten the bottem to be a little harder. All stock, we also had some cylinder mods to try as well.

Stock motor to stock motor the 800 has more power but a little further up the r's. To my mind it didn't feel super heavy like an x-2. now with all the same stuff you are gonna do to 701 done to the 800, it would still probably be stronger.

When Wavedemon hits lotto this year we will get it all done and have the proof.

It seems like the term "big power" and "budget" should be used loosely...when identically equipped it seems to be superior to the 701/760 platform. Its not a budget motor but when shopping smart can be done for a resonable price...right now it seems the biggest hangup is relying almost solely on WDK for parts.
Not trying to argue either way and like RMBC said, would like to see more people actually running this setup chime in.

Actually those two terms should not be used in the same sentence.:wavey:

This is why I am going with the 787 in my X2,its a proven engine setup,actually winning more races than any other engine in PWC history thus far, parts are all bolt on with the exception of the PTO coupler and rear mounting plate.The jetting specs and even complete jetting kits are easily found ,parts are readily available and it has decent power even in stock trim.Add a head,pipe and flame arrestor along with some case porting ,mild cylinder porting and total loss and you have a monster that weighs not much more than the stock powerplant.

There is a difference in the port timing between the 66V (GP1200R) and the 66E (GP800) cylinders. The exhaust port on the 66E cylinder is almost 2mm higher than the 66V cylinder.

There is some stuff in the works for running the GP800 but it is going to take a little time.

so what does it take to plant one in a square or roundie? I know how you feel about those hulls but you brought it up.

I would say you just need to make a rear mounting plate,glass in a front mount,make a coupler,which was actually really simple and find an aftermarket exhaust,without the exhaust its a no go fo sho.I still don't know which direction I am headed with the waterbox,for now its going in the Mach 5 with no waterbox,I will see how that turns out before I commit to doing that on the new hull.

here is the vid that got me motivated (stock longblock and electronics)


are you going to get that height on a bb motor? if not and you need a lamey then you could make a 66e conversion for cheaper.

I run a 927cc 66e. I think its a great reliable package. Its very low stress on the crank , cases, etc...its run great since I built it. I am no engine builder and I built it for cheap. I love the power it affords. I run stock electronics and everytime I hit the little green button it fires up. That to me is priceless.
