This is a Dyno Run from one of Berks customers.I think this is stylett9"s car but not sure. The cats give pretty good gains.

Are those numbers with just HFCs installed, or did the car already have a catback?

 

Berk HFC's where the only change made to the car.

The car wasn't even unstrapped from the dyno. Car already had Nismo exhaust, Y-pipe, & Fujita intake.

 

i just got a set of berks HFC today waiting to get them. Usually a HFC will give 4-6 whp and around 2-3 lbs/torque so i think berks is talking S***, but we will se im gonna dino my car (i also have fujita dual intake and apexi cat back so i want to see what i put down all together).

(im thinking i should put down around 270-275 WHP and 240-245 lbs/torque give or take)

 

Have you already dyno'd your Z?

 

Not a problem. Just do a before/after dyno. Keep the car strapped to the dyno. I don't see any reason why you shouldn't dyno within +/- 1HP of what we did.

But if you don't do a before baseline, how do will know how much power you are actually making?

 

That's EXACTLY why I asked if he did one already. Even though it's gonna be crap anyways since dynos are gonna differ, even if it's the same exact dyno.

Even better, go to the track and get a few runs in, then compare your trap speeds to the traps after you install the HFC's.

 

Absolutely agree with you.

To topless, here are our 07 dyno's. Test was done same day, same gas, same dyno. Car was not even unstrapped from the dyno.

That's awesome for being cats, BTW. Nice work. That's frickin' test pipe numbers.

 

yep..he sure was talkin alot of crap...

 

i have on my car as of right now an apexi exhaust and fujita dual intake. ill do a run with those parts first and then ill do a run, when i add the HFC with the apexi exhaust and fujita dual intake. ill post the nubers as soon as i get the HFC, hopefully very soon cause i have to store my car for winter.

 

Sweet! Let us know how it goes!

 

sweet

 

i will let you guys know but berks still havent even sent out my HFC. WTF!!!!!! is taking so long

 

hmm...berk??

 

Ceramics are on backorder right now. We've already cleared out all of the Magnaflow WD warehouses on the west coast.

Magnaflow just setup two more machines at their RSM facility. So supply shouldn't be too much of a problem after Dec 1st.

 

Thanks again Byran for all your help. The test pipes are sweet! I'm going to install them sometime this week. Hope to see good numbers at the dyno day next month.

 

(TO BERKS)
when i called in to order, and in the very begining of the first thread you mention metallic HFC. NOTHING ABOUT CERAMIC.

 

They are metallic for the 07.

 

yeah and since this is a thread for a VQ35HR then you would asum that its an 07 right?
