Are there any more specific rules/regs for the zz4 engine used in FX class? The UIM rules are not very detailed. What, if any, is the testing procedure for engines to determine if they're legal? I've looked all over and can't find anything, figured this would be a good place to ask. Thanks, Alex

The first and most importantly rule regarding the ZZ4 is that the engine must be a crate engine with absolutlely 0(zero) modifications, including no port matching or polishing of the intake. All numbers must be matching to factory numbers. When ever I did an after race inspection, compression of cylinders and bore scoping of the intake were my main focuses. We'll see this year. Wink

Thanks! Do you know if there is a written set of rules anywhere?

Not sure if this will help or if it's still relevant.....

Up until recently it has not been much of an issue. The class is now getting pretty big and yes it may attract these types of people. I know other forms of racing have big issues with cheating competetors. many things have been discussed although in the spirit of keeping things simple and affordable a solution has not been found to date.

Nominal engine specs are listed by GM. As far as port dimensions,valve job specifics,valve train dimensions,etc. Its is not specified. Yes there is room to cheat in there if someone wants to go that way. One thing is for sure when ever you have a motor involved someone will want to cheat. There was some talk about going to a sealed engine program (not that guys can't find a way around that also). The one thing we don't want is a 150 page book explaining every specdification for that particular engine to make it legal. It would be much easier to go the sealed crate class engine.

I can tell you. In the past some of the tech guys are pretty sharp and can spot things that a person might think they wouldn't.

In the end as it is wriiten there is room to cheat. Not to push the grey areas really as the spirit of the rules are clear but if some guy wants to cheat, they will. In the end I don't get what the point of it is, There is really no money to win and most guys do it for the thrill of the race. If you win a race cheating and win no extra money to speak of isn't an empty win?

If you go into a sealed engine you are cheating, there is no grey area. If you modify an engine within the confines of the rules you are not cheating, you are racing. It's no different then tweaking your intake, impeller, nozzle, etc. From what I see there are a lot of areas that can be modified as long as you don't change the few things that are listed in the rules. I haven't seen a written rule anywhere that says you aren't allowed to change "anything" in the engine. Clearly if you can buy a "legal" engine that's been modified then some modifications are presently "legal". If there isn't a rule prohibiting it, there is no grey area, it's up for grabs. I understand that most of you would like them all to be left untouched but unless you run a sealed engine program or create some new rules it simply won't happen, and at the end of the day it is racing not cruising. Competitive guys will always look for an advantage. The reason I'm looking for rules is to make sure I don't step out of bounds. I'm happy to work within the rules to gain an advantage and am not interested in cheating. Thanks again for the input, Alex

Thats the the grey area. What is within the confines of the rules. You say that if it's not written not to do then it's ok to do. That has not been the case in the past. The spirit of the rules are clear the specifics of the rules are not. Without a sealed engine requirement or a large multi page document I don't think it will get specific.

Also in order to protest a ruling it costs money and time. Then if you appeal that ruling which tends to go the way of the spirit of the rule (don't ask why I know that) it goes to the UIM in Europe and costs a crap more money.

I'm all for being competitive but I feel internal engine mods should be left to the mod classes. The actual boat is another thing. It is something that was biult from the grd up to start with being able modify it only helps in the advancement of technology.

These are just my experiences and as I don't race FX at this time so I am somewhat unbiased although I do believe that the same rules apply to CX class. The only reason that the CX class is not a sealed class is that it would not let any of the Ford or Dodge engine compete.

Has anyone tried a ford or dodge engine yet?

Gelnn Freeland tried a Ford 374W last year but had an oil cooler issue that filled the motor with river water and she blew up.

That sucks, be interesting to see if the other 's can reach the speeds of the Chevy. Thanks Boosted
