RJM GTR Intake Lower Manifold...oh yes!

Geez Harry take a chill pill bro! No one is trying to kick you off the forums... And as far as constructive criticism your giving none.

As stated before there are different methodologies to intake runner textures as there are many theories as to what one style versus another style could do. There is not a golden rule to intake runners however, from my experience you typically smooth out your exhaust runners to prevent carbon build up and the theory that rjmanufacturing is following on the intake runners is simply that by having a slight and I repeat slight rough surface on the intake runner your able to increase velocity of the airflow.

Again there are many approaches to intake runners and the results have varied from application to application.

I will stand by my statements as they are factual where as yours are based purely off assumptions.

As far as my dyno... Well let's see here we had an increased efficiency which meant my tune which was catered to the GTM manifold which is much less efficient was no longer applicable thus not an apples to apples comparison. Also I plan on being at zdayz which meant I did not have time to scrape my tune and do a full retune on my old kit and still make my sponsor obligations. Sooo excuse me if I choose to meet my financial and sponsor obligations...

Again I am basing all my info on facts...
