Why are ported or Large Throttle bodies shunned upon or deemed useless?

I too have maxed out the stocker.
thanks for pointing out the obvious there jeff :P
my point is, he said he maxed out the stock turbo (you too), with only intake, exhaust and cams. i am saying this is highly unlikely as i have the same mods and have not reached the max airflow of the turbo. i know for a fact the stock turbo can run 28 psi.... which assuming equal VE and engine speed, means you have a higher mass flow rate with a reasonable density ratio out of the intercooler. of course boost = heat. thats what an intercooler and methanol injection is for. stock turbo is good for 400whp as some have shown. cams, exhaust and intake is not 400hp.

I attribute the miniscule gains I got to the new clutch. I expect an upgraded TB would still be worth about nothing. .
Not sure where you guys are going with all that, but to answer the original question.
Ported / bigger TBs aren't big here because it's usually a mod that won't make much power unless you have other things to back it up. It's a good mod, it's just not a mod for someone that has trouble picking on o2 housing.

I'm about to bust out a newb question, flamers skip this post.
How do you measure how many lbs of airflow you are currently running? I checked my EcuFlash datalogs and didn't see anything seeming related.

with a mass airflow meter. the stock one measures it, however i beleive the output will be in Hz whereas you will need to find a conversion from Hz to lb/hr, lb/min or whatever relevant mass flow rate units you desire.

I agree it is a lot of work and probably not worth doing unless you do the manifold as well. I think in the buschur thread the mani was extrude honed and port matched both to the 65 and the head.
[QUOTE=Jeff_Jeske]It all comes down to airflow....the stock 16G is tapped out at 42LBS.... if you see 42LBS at 22psi turning the boost up to 27psi isn't going to do any good. Airflow = Power. Boost = Heat.QUOTE]

You cannot determine if a turbo is maxed out by MPH or DYNO. Weight shifting environmentals all affect those numbers. Running a snail outside of it efficiency range will have next to no returns.
As for the TB.... if the TB is bigger than the IC piping I doubt its gonna do much good. Furthermore it will require more tuning of fuel trims and idle control.

Geez fellas relax lol. I have posted pics of her before. To be specific, in the girlfriends pic thread a while ago. https://www.evolutionm.net/forums/sh...&postcount=109
