. Ford's dyno chart shows it @ 350hp using a 500cfm 2bbl carb, so with that combo it's right at the ZZ4/CT355 levels. ...i think that being allowed 750CFM 4 bbls would put that ford engine well above target HP ratings.having different carb specs for every engine might really complicate the fx formula.just my two cents..... _________________ if ya cant hit bottom ,beat the hell outta the sides |

i also think that dyno tuning should not be allowed because i know for a fact that they are squeezing 370hp+ out of the zz4.crate motor class should be exactley that out of the crate into the boat not out of the crate onto the dyno...how is that fair to the 9-5 racer that cant justifie the extra cost of a dyno tuned engine. |

That would be next to impossible to control. As long as the adjustments are just timing and fuel I don't see a problem. Now if they start to fool with rocker arm adjustments and cam timing that is another question and I would consider that the same as porting or changing camshafts.
Most zz4 engines dyno at close to 370 right out of the box. _________________ Mark

Hey Will R. what changes are they making to the ct-zz4 to get 370+hp,just wondering. I have to agree on the dyno sheet thing no need. |

As i was typing boosted threw in 370 hp out of ct-zz4, are they 350,355,370 or 370+out of the crate. I guess thats why i asked Will R. if his bud had a dyno sheet on the 392/475hp, nice to see the performance shop sheets to compare with factory thats all i was getting at.Later. |

i like where your goin with this Will.there are already formulas for the folks that can afford to build $25000 + engines .crate engine classes should be just that so some of us peasants can have a crack at 'er as well. _________________ if ya cant hit bottom ,beat the hell outta the sides |

No doubt about it Will is has got the right idea. Anything that can get competitive racing cheaper is going to help the sport. In fact the fx class is the first class ever that you could actually race for free. Ha jet boat racing and free just don't go together With the amount of entries and if one person won all the races they would come close to paying for almost all there racing costs minus the boat of course. Add a few more boats and we could call the fx class the proffesional class.
At any rate the more the better and what Will is trying to do is exactly that I am all for adding the Ford engine to the fx class. _________________ Mark

I think there is something wrong with your math Will. your saying it is wrong to spend $700 on a dyno session but allright to spend 2 grand more on a ford fx engine. while i do think the ls3 and 392 ford would be great head to head in a new class we must be very careful with fx as it by far the most sucessfull one going. If a new engine was to come in that had a significant advantage it could have the opposite effect and hurt the class as not everone would be willing to switch To continue on the subject of dyno use it is my belief it is cheaper in the long run to tune this way than experiment in the boat where it is very easy to hurt parts also if people are willing to share there info it takes the guess work out of setting up an engine packgage for example if you look at one of the ls dyno sheets we posted it gives you carb size and jetting, optimun timing, header info best operating rpm etc. For somone new interested in the class it gives them a great base line to work from. |

I like your thinkin about set up Rob! (Although you do need to use this button{. . . . . . } more! I would like to start racing fx in the near future, and the fact that you get get a 90mph boat and race it for $20-$35,000.00 is very appealling. If that's not enough the ls/ford mill will offer 100mph....I'm really not intrested in doing a 100mph + so that would be a great stepping stone for the guys starting out or on a strict budget.
I also like what Will said about ford Vs CHEV. It brings alot of new fans when they have 'Their' personal favorite running the race. Look at NASCAR and Motocross....it's alot about the teams and who can make there equipment faster!
P.S.....I Don't like ford!!! But still find myself cheering for Spencer when Whitey's not racing 'U'!! |

Was not ford and dodge engines an option in the beging of the FX class. I assumed that the main reason they got cut is that nobody ran anything but the ZZ4.
Don't get me wrong I'm a die hard ford fan. But I think we missed the boat on this one. |

That is correct the idea was it would be easier to police and more competitve if it was refined down to one engine |

My thoughts are that if I wanted to be in the 'Starting' class, and had to buy a ford.....I would wait and save up for the next option that offered something better. Couldn't bring myself to buy anything ford,Polaris etc......My2! |

first off if anyone here was at the meeting that determined to be zz4 only was not because of the fact that everyone was running them it was because ford discontinued the gt40 351 and had no replacement option at the time but now they do so hence the reason i brought it up.
second trust me rob there is nothing wrong with my math...i just wanted the option to be there for the guy or gal that if THEY want to spend the extra 2gs to run the motor they want the choice should be up to them.
third after reading your post rob i have changed my opinion on the dyno as long as the results are posted like you said for everyone to see...yes is a very good idea but with this class i am sticking to i think the class should be sealed race motor only though ct350/355 and or the ford 347/350 |

Rob if you are lookng for a MSD ign controller for the COP ign, or a750/ 850 carb let me know. I am sure you have access to all the stuff but just in case. _________________ Mark
