Am going to put an LS2 90mm inlet onto an LS6 intake manifold & am looking for any dyno information documented after opening the LS6 intake inlet. Searched under many different words that may have been related to the subject & found nothing. Any information will be helpful. Thank-you

Am changing from my 85mm ported aluminum Weiand to the LS6 solely to reduce front end weight & don't want to lose any power in the process. The car is also corner weight balanced. I have tuning software & have documented pressure & airflow through the Weiand & will be able to compare this information to the 90mm LS6 set-up. Please no "why not a FAST" suggestions.

Have read many tuner statements that suggest that the limited LS6 inlet size causes more of a restriction than the runner. Any dyno information will be greatly appreciated. Thank-you

TPIS does this mod to LS6 intakes:

They also post results for a number of intakes. I would like to see more results from users with different head & cam combos:

Thanks for the links. It looks like I wont lose anything & may actually gain a few, as a result of the swap. It may be a while, but, I will post a comparison in airflow & pressure between the two set-ups. Will include all engine mods & other important information.

there is a thread in the southern section were a guy installed the tpis 90mm ls6 intake and gained 18 rwhp. he didnt mention how much torque he gained, but im sure it was a descent amount. His mods were a mid size cam and all bolt-ons. The thread is only a few weeks old you may be able to dig it up
