2016 3.0 turbo rule changes

I wouldn't mind seeing bar tires. IMO it would save money. Set of good pullers will last several seasons.

I'd like to do bar tires also. Expect the fact that it's going to cost a chunk to get them setup the first time. Good thing I like about dots is you can run them a year and sell them on Craigslist for same price as you paid for them I'd you'll shop arounso when buying them. But then again I'm broke un like most pullers lol
 
Or take the 3.0 and make it the old school 2.8 class with some differences cab interior optional and open driveline is still good.
 
Turbo must be a smooth 3.2” max inlet diameter. To be measured with round 3.25”slug. No MWE groove allowed. No alterations to allow air to compressor wheel other than 3.2” bore are allowed. Compressor cover and compressor wheel must be smooth contoured. 3.25” slug not allowed to contact compressor wheel.

get the power level back down to 14-1500hp where a 5.9 block can live for a couple seasons and get our truck count back and go have fun. no one will be able to tell 16-1800hp truck that are now 14-1500hp except our checkbooks. it could be an attractive class for a 2.6 guy making 1300hp with a hx 60 who is replacing r/p every three hooks to put a wheel and cover on his turbo and be able to run a dropbox reverser and a big rear end. imo the 3.0 class is dying and something has to change. more power is definetly not the answer.

A true drop in wheel hx60,s400 class has been what I thought would be great for years. People would be very surprised how good they still would run. Our 3x3.6 class here is fun. We are all still running the old 3.0 turbos from 6-7 years ago. They make pretty daMN good power still and motors are stupid cheap to build. We had a hx60 truck in top 10 at ts this year. And a truck that runs with us with a s500 in top 6 without a deck plate. And that motor has lived for a few years now. I do agree less hp is what this class needs to grow. Or even to make some other 2.6 trucks bump. I believe 2.6 and 3.0 could combine with a nice turbo rule and be a good class.

I assume you meant S400 since you only allow a 3.6 turbine not 3.9.

No its a 500. They run it with a bushing welded into the exhaust since they already had the turbo before we decided on rules. They haven't run away from the hx60s like that so all is good.

I'd personally like to see 2.6 get limited to a 3.35 turbine and eliminate some I the grey area with these covers for both classes and 3.0 to go back to 3.0x3.6 and this sport would be pretty crazy competitive.. But it'll never happen. So I'm all for this 3.0 smooth w/ odl and 3.6 smooth with cut
 
The reason i would guess that they want smooth bore turbos is because of all the map grooves being messed with. Every pull has a turbo that someone pushed the limits on. Smooth bore cuts all that out. Makes it all simple. I have been hearing 3.0 will have the same rules with a bigger turbo (smooth bore) with cut tires. 2.6 will get a 3.0 (smooth bore) and they might open the drive line up. The just what i have been told from class reps in sanctioning PPL clubs. Not in stone just what they have talked about.
 
F 2.6 smooth bore in 2.5. 2.75 smooth is where its at. Theirs a ton of them out there and their already mastered on the tractor world.

If all these turbos in smooth bore classes are "mastered" like I keep hearing, why do they always have a better one available each year?

This idea that smooth bore will change the outcome of who wins every year is naive.
 
Nobody said it would change the outcome, at least I didn't. I'll continue to spend coin on the best wheels and covers if not then I'll fall behind. "mastered" was not a good choice of word. that's when we stop becoming innovative if that's the case. Your opinion on this has changed over the last year because pretty sure Eric and yourself were wanting smooth bore broke to buying my first turbo. I personally like smooth bore. On a local level techs cannot do anything beside throw a plug in. Going smooth IMO will keep power the same it is now, eliminate all the teching issues and push manufactures to design better wheels and wheel/turbine/housing combo. You sell turbos so their may be a lot of downfalls from a manufacturing/building standpoint, but as a puller I like the idea of smooth bore.

I don't think many people think that. I think most people realize that certain customers and shops get covers and wheels that are a year or two away from public release anyways. That's ok and it makes sense for everybody involved.

I think what it will do is make the difference smaller and the gain smaller so if someone buys a charger this year he knows he's not 150hp down in two years but maybe 20-30. I also agree it making tech easier and the opportunity to have rules that don't need to be specific enough to cover every grey area.

BTW.....I am all for exploiting grey areas that aren't covered in the rules. I do it every year because I can't afford the HP that the tops trucks can so I need to find an advantage other places.

Yes we both wanted smooth bore last year, and the year before, but it fell on deaf ears. But now we don't want the people that have bought new turbos to be forced to buy another new one, you seem to not realize we are trying to help the pullers here.

That thinking is my concern, people need to understand that there are large power differences in the smooth bore classes also, don't be fooled into thinking you can buy a $750 turbo and be competitive, that is wishful thinking.
 
The current harts 4.1 smooth charger has not had an update in 4 seasons. The current smooth 3x3 had an updated wheel last year and it was a 30hp gain.

Smooth will most certainly tighten up the hp gap in the class. Funny how opinions change when your making money selling turbos in the class

It seems we all buy new turbos every year anyways. I have seen 4 different variations of your floating bore covers. Don't get me wrong, I love the fact that you guys are doing what you are with the covers, it simply works. You are also changing it all the time finding power here and there. Next years turbo rolling off the machines will be different than this years turbo, smooth bore or not. Power will be the reason and the heavy hitters will certainly upgrade.
