Got my Throttle Body and Intake Manifold ported and polished today, waiting for Valve Cover and Intake Mani to be painted and getting the car back tomorrow. Excited. But what power gains do you think? Thanks to SGM Tuning Concepts (my buddy scott)

I've heard there not a whole lot to gain from porting either of those actually..I was gonna buy a spare, send it off an have em do the same a while back, but I ended up changin my mind

TheBoss8688

It will help some. Probably in throttle response and spool time.

Ported my own TB and picked up 8HP

Mongo, was 8HP worth the trouble?

TheBoss8688

It's easy to pull and 8hp is more than the other guys. It's worth it to me

how much of a hassle was it to take the intake mani off?

Easy is a relative term. I was actually referring to the actual porting. That seems like it would take lots of time to do right.

my buddy had his ported by a local shop. layed down 299 before porting and layed down 330WHP with intake porting and a injen intake. not sure on how many HP he freed up with porting the IM

I allready had a extra TB and manifold sitting around so I did those when I was bored and just switched them out in about an hour.

TheBoss8688

Yup. You can pull vavle cover in about 5-10 min and intake manifold maybe 10-15 min. It can be tricky getting out of there

Sounds like the shop played with the dyno settings to justify the price of porting to the owner. What car was this? 10whp i could see but 30whp umm no. They play with the tune as well?

09TcSedan

not sure if they messed with the tune. he had the Hahn PPG tune or whatever its called. they made IC pipe for his car too. with the stock air box,Hahn full exhaust and hahn tuner he layed down 299 i cant remember the TQ number but after the intake,ported mani and IC pipe he layed down 331WHP and 370 TQ

Intake probably did a good bit of the gains because of freeing up the intake side of the turbo, and it probably skewed the fuel trims lean too.

theres not a ton to port in there.. just smooth everything out. thats the biggest gain imho. the exhaust manifold its worth the trouble one bit as its damn near close to being gasket matched already
