New Dyno Results From Momentum Headers

SPOHN · 12-12-2012, 03:27 PM

Well finally after having my new Momentum Headers put on I got her tuned again today at Forged Performance. As always it's a busy place so I'm glad the crew could slide me in. Nothing like seeing so many wonderful builds goings on in one place. Love being there.

For a quick run down before I post the dyno sheet. The first time I had my car tuned I had Stillen G3, GTM test pipes, and Greddy TI-C exhaust (silencer removed). Take note that on Forged dyno (dyno dynamics) it reads lower than most dynos. I'll give a reference shortly. Anyways the first tune I put down 292whp with the above mods. Then days later I put 310whp on Z1 Motorsports dyno (dyno jet). So that gives you a reference of the difference.

Well today after installing Momentum Headers and retune we put down 316whp. So that's 24whp since the last tune. So that's a great gain from headers alone. Definitely the best headers on the market and the price makes it that much more pleasent. I have a good feeling that on Z1's dyno it will put down 330whp+. This is about the only mod I've ever done that I've actually felt the power increase.

Good numbers, when would you like to schedule that dyno run ?

LukasC · 12-12-2012, 03:34 PM

Nice numbers man! Im making 313 on a dynojet so with those probably 335ish?? Could be worth the money!

How's the sound? I'm going to assume there's a little bit of rasp, but how much?

Hard to say. My car is flat out just loud. Hard to separate the two.

I am really curious how this combo would stack up with my SC.

Hard to say for sure. The stock manifolds do flow great. Be hard to know if there's really much to add when already FI.

Exactly, I think my main plan for my exhaust setup is just throwing on some TP and then getting a retune. I just keep waiting because I want my next tune to include VVEL.

TP's for sure. They always help great. I wouldn't worry about the VVEL so much. The system works great as is. Someone is going to have to go threw trial and error before the VVEL really gets sorted out.

Yeah, and I always wonder if you start messing with that will it really need some other upgrades to benefit which creates the spiral of if I do A then I should do B which leads to C and all the way.
