Did you sand it by hand or did u used a special sanding machine or did you took it some were for that, also do I have to send mine to eps I also bought the eps throttle body's but I didn't know I need to send them y thought they would fit just like that

The polishing was done by Synergy Composites in Indianapolis. With respect to the throttle bodies and port matching, I recommend you reach out to EPS Tuning, they are very quick at responding msg's and their customer service is top-notch! I'm very sure they will take care of you.

Just wondering, why not have them port-matched at Synergy since you had the manifold there being polished? I had him port match my upper/lower manifolds along with the billet adapter for the EPS TBs to the upper intake manifold.

Bro can you please tell me how to contact synergy composites, and also ca you tell me how much did it cost, i planned to do mine by my self but is to much work and i havent had the time i been working a lot at my job also if i do it by hand y dont think i'll be able to get a finish that looks that pro, so i would like to send mine

yea I've talk to the guys from eps before, they are cool they have an excellent customer service they even recommend some one to tune my car here in CALI, i haven't done it i because y haven't install anything yet because i want to sand and polish my manifold first so i put everything at the same time (intake, throotle bodys and manifold) i will message them ones i polish my manifold.

Thanks for the answer bro.

More details on the setup with this manifold HERE

Any news yet? Gains? Losses?

There is lots of news in this debacle of a thread that you obviously didn't read. I doubt they're actually going to post evidence of power loss from a product they had to take pre-orders for to R&D the damn thing...

Yah but not everybody has a nice ceramic coated one like this.
And its easy to lose power by opening up the intake side of the engine. High RPM HP's are there to be had but there is plenty of low end torque and power to be lost with larger runners etc.

Plus I've been subscribed since this thread started.

Check the link above your post

So it looks like the cost of that manifold alone will get you a proper intake and exhaust. Hmmm.

Or 1/3 the way to TopgunZ's new supercharger kit
