View Full Version : Port and Polished Exhaust Manifold, quite a surprise!!!!

Well my K03 sport was making the infamous dentist drill sound and when I took it apart, I decided that it was a good time to put on our port and polished exhaust manifold. So after we started it up, after battling a tedious exhaust leak, we finally took her out for a test drive. And boy were we surprised. The car pulled noticeably stronger and boost held a little longer than before. Spoolup was also much shorter and boost was earlier than before.

Bear in mind that this is equipped with sh!tty Neuspeed programming. I bet if it were with a GIAC or APR chip, the yield would be much better.

Ultimately, with all our testing it only shows that our stock K03 is way too small and lacks top end. While this manifold may not cure the K03's horrible top end, we find that it is defitnitely a great bang for buck mod for those who cant afford or choose not to go for a turbo bigger than a K04. This mod is definetely a better mod in price and gains than any given intake kit.

Cheers,

Our master tech.

I guess the link was hard to see under my name in the original post.

is this something one can do themselves? or do I need special high tech gadgets?

You can try yourself at your own risk. Most consider port and polishing as an art more than a skill. It takes a trained eye as well as a steady hand. Our master tech has been doing this for years and has undergone rigorous training. Also, in most cases what looks good doesnt necessarily perform well. Proper tools i.e. flow bench are the only way to insure that airflow is maximized.

So what would be the charge for doing something like this at your shop?

In the past, most of our services were targeted towards subarus. Lately we've started some R&D on our own project B5. We hope to have our site updated with more current Audi/VW information and pictures. Expect to see big changes with the site in the next couple days (I promise that this will not be "two weeks").

We have done mostly local work for a few audi customers at 200 for the port and polish/manifold and 125+shipping for the service alone.

We also carry multiple manifolds for customers in need of core exchanges. This requires a $75 deposit that will be refunded upon return of your stock manifold.

cool nice to see you postin on AZ. i always see your car by MLK and Chicago on the corner with all the Subarus and VWs on the driveway when im going to RCC in the morning. we should meet up sometime again man. Go and get a GIAC chip on your car and put your new mani to its fullest potential![up]

Hhhhmmm, I might be interested in this service. That is a good price for the service. Other places charge more.

apparently you guys haven't been around long enough to see manifold cracking both stock cores and ported pieces.

good prices and the turbine entry angles are pretty well defined considering.

thanks for contributing to the market, hope to see more from you guys

Thanks for the compliment bitterchild.


We actually have noticed a lot of the stock manifolds with cracks near the manifold outlet. This is one reason we really spread caution to all of those attempting this. With regards to the manifold outlet, we were able to increase flow even futher on a earlier manifolds. however, because of the cracks we encountered, we believe that the final product above has the most efficient port that wouldn't further jeopardize the integrity of the manifold.

All stock mani's crack regardless. Porting it will just futher weaken its structural integrity.

well if you could take a new old stock mani and cryo then coat it. It might do a little better. then again that's squeezing juice out of a bean

i have this manifold... i wish i can tell you if it made a difference but i put it on right after i bought a new motor and put in a couple other parts at the same time. but the car does pull stronger. That might contribute to the fact that i had perfect compression with the new motor.

do you think this power gain from port and polishing will be noticable for us 2.8 guys also?
if so i might be visiting your shop soon.

You and bitterchild make it seem like every manifold is cracked... I don't think this is as much of an issue as you make it out to be. I haven't seen or heard of ANY issues at my dealer, at stock boost levels anyway...

For stock applications, you will be fine (though you'll always have a hairline crack). As soon as boost levels and heat increase, the stock manifold (ported or unported) WILL crack. Perhaps I am running a bit too much power (320whp+ GT28RS on adapter plate), but as soon as I had the stock manifold ported, it cracked within a month. It's not the actual outside that cracks, it is typically the collector to runners 2 and 3 that starts from a hairline crack, to eventually splitting in half.

Are you able to do this for 2.8s? Do you think the power difference will be worth $200?

hey whipped, when are you getting supercharged?

bitterchild
12-10-2005, 05:05 PM
a chipped k03 likely puts more stress on the manifold due to the heat and high backpressure. Then again a big ass turbo dumping fuel out w/ timing retard isn't any better. All I know is that it is well documented that the stock manifolds crack pretty much no matter what.

after i got enough money from man whoring..lol...still workin on it dude..

now back to the question..
WILL THIS BE WORTH IT FOR US 2.8 GUYS?????

I just took a look at your website, and your pricing list.. Is this for Audi's as well? Also, how beneficial would these services be for a Naturally Aspirated Audi?

Thanks in Advance

Currently, our only VAG project car is a 1.8t but we have been beta testing some exhaust manifolds for some local 2.8 customers. If anyone is interested, we are still looking for some local 2.8 beta testers for manifolds.
Throttle bodies on the other hand have completed testing for both 2.8 30V and 12V cars and have shown significant results in both throttle response across the powerband especially up top. For those of you that remember, TAP use to sell a ported throttle body but we can just port them and send them back to immediately. Turn around for throttle bodies are 1 business day with a downtime of no more than 3-4 business days.

While the pricing that is listed on our website is specifically for Subarus at the moment, you can contact us for pricing which should be pretty close to what we have listed.

can u polish an ATP mani?

bitterchild
12-14-2005, 08:03 AM
should be a bit less since that 1.8t mani is a lot easier to pnp than your average subaru manifold

Ouch.
We'd like to see some flow bench comparisons (stats) on stock vs the port/polished unit to be able to justify the down time and money spent on something like this.
Butt dyno is one thing, documented stats is another.

When R&D is officially complete for 2.8 manifolds, we will provide flow tests and eventually dyno plots of before and after. Preliminary results from the 1.8T manifolds have yielded an increase of 14-17% (at 14.7 psi) in flow.

so far we have great feedback from the community. Keep an eye out for even more stuff with pics to come.
