Who can port a SS manifold?
Looks like I'm going to put my hands on a second SS manifold and I'll be looking for someone to port and polish it for me. Who can do it?

lol well seeing as the manifolds are made out of Nylon.. or a plastic basically. They cant be polished. And porting them would be very difficult due to the material as well. Thats why there aren't many responses. I would also think the V8 bolt on section would be a better spot for this too mayb. Good luck with results.

We do them (never polish a port job...that was what we did in the 60's and 70's before we found it cost power) but they are so time consuming dont really advertise. I have several yet to finish here. When we get a 5 axis CNC machine we will develope a program to do them.

its pretty much a waste of time. unless u just taking it off anyway . if u look at most of the sponsors that port them do a lil research u will see they dont do as advertised . but they will see some do 3-5 rwhp. but u see some do 3-5 loss too. if u going bigger tb , bigger c.i.d. then i would look into it more but dont see the chances and money being spent on it. ive seen alot of 3rd party testing and it 75% of the time or more . they show no gains to -2 to +2 hp the other 24% . the other 1% is the +3 range lol

I literally picked up 12 rwtq and 15 rwhp on my friends cammed ls3 car, with only intake manifold modifications. Testing was done within 2 hrs on the same day, same conditions, and no tuning changes. AFR was the same, timing was the same. You just have to know what to modify, its not just a "hog it out" ordeal.

rhino , not sayin it cant be done but u know as well as me. most dont see those gains. but it does happen time to time. merc i hope u do gain something. but dont be disappointed when its not what they tell u. just do a quick search on ls1tech or google .
make sure u say ls3 intake. cause yes other intakes do respond much better to porting. |

There is work to do other than just porting and removing material. That's where the gains are. I agree just removing material, and generic porting will not yield gains. It didn't on my car. But when I researched some more, I found some good info on things to try, and they did help, to my surprise....lol. I have done it on about 3-4 cars now and all have shown similar gains. Porting the ports does nothing, opening the throat up does nothing, cutting the stands out does nothing. Actually I will say that without touching any of those areas, I can get 5-10 tq and about that much power too!
