Can you guys tell if this is a 112 or a 122? It was pulled from a 2002 2500HD with a 6.0L. Thanks! I did a 2004 LQ4/ 80E swap into a 92 GMC last year for a customer and he is toying with the idea of Magnacharging it. I doubt he will ever try to max it out so I wonder if a 112 would be ok for his intentions. It will never see the track, he just wants a little more than stock. Opinions?

 

Looks just like my 112.

 

That's the 112. 112 has 10 splines on the case while the 122 has 12. If all he wants is 'just a little more' than stock, then the 112 at 5psi will be fine.

 

Do you guys know from experience what max boost with a 2.6" pulley on a 112 on a stock cam 6.0 with oe manifolds with 2.5" y pipe to 3" facory style muffler. Could he see 7-8#s?

Thanks for the help guys!

 

I saw 7lbs of boost on my stock LQ4 with a 112 and a 3.1 pulley

 

Wow, in that case I think a 112 will serve him well. Thanks for the replies. You guys are always very helpful!

 

What's next Brint? I'll give you a ring tomorrow. Have a question for you.

 

I have a lot of good side work lined up if I can sqeeze the time out with the new bambino. First up is tonys truck. Gonna redo his twin 255s like the twin build on here a while back. Gonna be free but he really needs help. He is a little over 20k deep and hasent even got to drive it 5 days.

I know your opinion on the topic at hand but what if joe isn't too power hungry? I wish you could've seen the finished swap. By far my best work.

 

I think a 112 with a 2.6 pulley your iat's will be through the roof....unless you are running meth.I have a 2.8 pulley and seeing about 11# of boost.

 

My man said he would want to gain 125 whp to make it worth while any more would be a plus.112, stock 6.0 =??? Max Rwhp gain
