Promoter USA-EAST
thanks to everyone who chimed in on this subject. we have now 'revised' the rules to reflect some of the ideas that were presented. this will be adopted next Tuesday at the USA-EAST rules meeting so there is still room for additional changes, if necessary.

So here's the proposed amendments:

Turbo - rules as written, allow stock replacement wheels that fit in the unmodified stock housing, e.g., Batmos are legal. Pullers need to be prepared to pull the intake so the compressor can be teched. Yes, they know teching these are going to be a PITA.

Weight - 8500# to allow some of the newer trucks to enter without having to rip seats out, etc.

Bumpers - rule remains as written. No big fabbed bumpers.

Did I miss anything?
 
So teck will have specs on all the different turbo sizes from year to year?

From my smart car.

Yeah I told Cory he was gonna need a laminated card or something.

We also thought of just making a plug for example for the largest of the Dmax stock turbos, and just apply that to all Dmaxes (all the VNT chargers are pretty close). You would need one like that for the Fords and Dodges I suppose.

There's other ways to skin the cat probably.

On the billet wheels, we agreed that it would be pretty frustrating to have tech deciding what is a billet wheel and what is a cast wheel, etc., so we all figured we would eliminate that and if someone wants to buy a stock replacement Batmo or whoever, then all they'll need to do is plug check it and make sure the housings are untouched.

If a couple trucks dominate the class I'm sure there will be lots of debate.

Rick said that it's going to be a budget class with low payouts. I guess if someone wants to spend 10G's to win $50, well, that is your right to do...

Doing quick math.. kinda like spending 100k to win $500? It will be done.
 
So a duramax turbo is not allowed on the 6.0l the lly duramax turbo 63.5mm is uses as a upgrade on the 6.0l aka as powermax. Just in the ford housing.
