In another thread under NADM, we started a discussion of limitations for a 2.6 turbo. It was asked if there is or should be a compressor exducer limit size. I believe the 2.6 class is an entry level class, therefore rules should be set forth to even the playing field on trucks. Allowing clipped wheels and other modified chargers may be more than what an entry level puller can afford/build and deter people from entering the sport. I had mentioned the possibility of having T3 flange only, but I'm not positive on the exhaust setups for ford and chevy. I am interested in hearing peoples opinion on this. I really don't care either way, I can build my truck accordingly, but I am just trying to look out for the best interest of the sport.
 
really cant have the t3 rule to many other chargers, hx50,t4,t6, bullseye housing.
 
Heck you can buy a t4 charger cheaper than you can a high performance t3(s300) turbo
 
Most cutting edge 2.6 chargers can be had for less than the retail price of the sports most popular chargers (Silver bullet, HTT 71series). Who builds them makes all the difference.
 
I think there just needs to be an exducer limit on the compressor wheel. If there is no exducer limit then you will have people who are running 3.0 chargers in the 2.6 class, with custom compressor covers and back cut wheels. 66mm inducer, 100mm exducer would be good I think.
 
This is why Im waiting till all the rules are published before I buy my 2.6 charger for nest season. I hope they allow t4 flanges.

Its hard to believe that a silver bullet technacally shouldnt even pass a 2.6 plug and a 465 flowing alot more air is legal. If i cant move my hx50, i will probably try to get a 2.6 housing made for it. Tim
 
Exducer is too hard to tech on a Ford or Chevy. Why do you think their getting away from it. These questions should have been taken directly to tech and not put out in the open. You have just opened the door for them to make it a whole lot tougher than it should be.
 
then buy a dodge.....lol, I dont know what to tell you, you cant keep allowing the turbo rules to change every year. esp. when those rules revolve around alot of money.
 
If exducer is to hard to tech which i say it is, then maybe 2.6 turbos should be certified by the sanctioning org. Just like a cert card for clutches, each turbo should come with one wether it is from II, HTT, Schieds or E.D and upon finishing in top 5, be subject to tech verification at any time through out the year. If a makers turbo should get teched and happen to not pass, there turbos will no longer be allowed. This will make them follow the guidelines for size because they would not want there turbos banned. The pullers will have no choice but to buy a 2.6 ment for the class.

Do you think something like that would work? Tim
 
I dont understand the point of the card if you show that to them to not get teched but then get teched what was the point of the card? I think it should be up to the competitors if you feel like getting someone teched then throw up the cash and tech them. If you pass 99.9% of the time you arent going to be teched again. You have to have some sort of tech you can just show a card and be like ok. you could have a card for a turbo purchased but not actually on the truck?

That wouldnt bother us. Its becoming more difficult to tech these trucks accurately and efficiently. Look at the Scheids event, that would consume a bunch of time pulling every cover. Depending on how the truck is set up its a downright pain. If the pulling sanctioning bodies could agree, we could conform.

Because if the turbo maker scribs a serial number with the turbo, it will match the card. Lets say you run a E.D. turbo and are kickin ass, at some point through out the year you could get spot teched. E.D will build it to the size rules because it is their ass on the line. That would put the honesty in a few hands instead of hundreds of pullers. Who do you think is going to be more honest, a bunch of pullers wanting to win or turbo builder wanting to sell their turbos. My guess is the builders. Tim

I think it would be a fair and easy way to tech turbos. All the techs would do is check card number to turbo number. Yes companies could still cheat, but throw in the random spot tech along with the possibilities of not having your turbos allowed, i would say all makers would follow the rules. Tim

There are no perfect solutions to this. Its good to see people discussing it and brainstorming. Some of it has to be left open to change or you end up with the 2.6 class featuring the T.O.T (Truck Of Tomorrow) where they are cookie cutter and everyone is darn near the same. As the guys building these things our input is mute. Thats the beauty of cutting your own parts, they dont know what they are going to end up as till you factor in the rules.
 
Chris, ya i dont know that there is anything that can be done either and i understand the cookie cutter parts so i can see both sides. I was just thinking out loud.

I know II will build you a legal 2.6 class silverbullet that will pass spec

Im thinking that or HTTurbo Competition66
 
ITPA has a max limit on the outer housing. Basically locking the 2.8 bushing class to a s400 or gt42 charger.
