I understand, but somehow that just doesn't seem right to me. Not to be a pessimist but I haven't seen these kinds of gains on NA japanese vehicles with the simple addition of HFC's.

Anyhow I hope to be proven wrong with further independent dyno testing...

The numbers speak for themselves on this one single car. It shows you the power potenital of the BERK HFC's. On the G37's, a 12rwhp gain is TYPICAL, So 19rwhp isn't impossible. I encourage you guys to do your own dyno's as well and see what they make on YOUR car.

My 350Z HR with just cats and adjusting my UPREV tune went from 265 rwhp to 273 rwhp and from 232~ tq to 245 tq. This was with just Berk HFCs on a stock exhaust stock intake HR 350Z NISMO.

Nice work DD...

So, if I am reading the dyno sheet right, the torque went down slightly, but it is much smoother. Is that correct?

Would the addition of a Nismo type exhaust cause enough reduction in backpressure to lower the torque output? Would that sound be to obnoxious?? I may have to take clients for a drive sometime and I don't want the car to be too obnoxious.

HFCs + Mazdaspeed exhaust on the RX8 would have made it too loud for me. Will it be the same here?

Do you have the Nismo exhaust already? If you do and its too quiet, then the HFCs are the next logical step. If you don't, get just the HFCs first and then decide if you want the Nismo exhaust. I haven't heard the Nismo exhaust in person to be able to tell you how loud it will be.

nice gain . I read somewhere that VQ37VHR and VQ35HR can gain good numbers by changing things like HFC and Cat-back

bboypuertoroc · 02-04-2009, 02:38 PM

Nice gains. Awesome in fact for HFCs.

No reason for any doubt in the numbers here... it's just a before and after dyno. It's all testing. YOU'RE results might vary since it's a different car on a different dyno, same as anyone else.

Do you have a dyno of the same car with the Berk Test Pipes?? Just curious to see the difference between their HFCs and Test Pipes.....

Nope, nobody with a 370Z has the test pipes yet.

Any dyno results between the test pipe and HFC?

Unfortunately I don't know of anyone who has dynoed with these test pipes yet. Wanna be the first?
