2.6 turbo rule change? I'm lost. - Competition Diesel.Com

mech2161 · 02-01-2009, 04:51 PM

Here's what is on the NADM site.

Turbocharger: The vehicle is limited to a single turbocharger; the inducer bore on the
compressor housing may be 2.6”. The inlet will be measured using a 2.65-inch plug or internal
calipers. Bushing from any larger turbo size down to a 2.6 turbo is PROHIBITED. A stock
map width enhancement (MWE) groove is allowed. No MWE groove will be allowed that has a
width greater than 1/4 inch. All provisions allowing air to the wheel other than via the bore and
the MWE groove are prohibited. 6.4 liter Powerstroke engines may utilize the factory twin-turbo
configuration.

I don't see that here.

As long as the cover is 2.6", u cant have any type of bushing bolted to a 3.0" cover to make it a 2.6" bore.

Thats one thing that makes this class such a good one IMO.

*2Tone12V* · 02-01-2009, 07:23 PM

Thats how I read it as well. I agree. This makes it more of a true 2.6 class.

So they made a change after Gene Posted the rules. I would think they should have made mention to that here.

Yea, the compressor housing is all that matters. No bushings are allowed. As long as the inlet is 2.6, without any type of bushing, it is legal.

As to posting it up on here, I'm sure Gene meant to. He posts it on here just to help yall out, he doesn't have to but does anyways.

No bushings in NADM 2.6,but good find Kevin. That particular line was changed a few times, and the wrong one made it to the website some how.

This is the way it was supposed to read"

"Bushing from any larger turbo size down to a 2.6 turbo is PROHIBITED."

Now I'm getting freaked out, the right line is in there... I think we have a weird link.

Geez, Gene got back to work awfully quick after the game

mech2161 · 02-01-2009, 09:21 PM

I wish I'd have found it sooner. We made some rules for two other places that allow it.
