to red370: the video is so f-ing epic. lol +1 rep added!

Thanks Red370, that does sound really nice. I cant wait to look at the tests on the 2 to see power differences.

So far, independent dyno wise, the Stillen and FI have made the most power, averaging between 15-20whp per, havent seen any from the Berk setup yet.

So in a nut shell its safe to say the Stillen, Berk, F.I cat backs will all give 15whp increase.

But doesnt the Stillen run a Y-pipe? The dyno's and website claims a 18whp increase. Is that right? Where would the design of the stillen exhaust make up the numbers due to the setback of having a Y - pipe? I was under the impression the best gains come from a X-pipe, Please correct me if I'm wrong....

Nice collaboration on this one!

I can't show modeling equations or anything, but if the Y-pipe is designed well and has a large enough diameter where the Y merges, it shouldn't be restrictive.

I'm pretty sure there was a post with dyno results with berk awhile back before the 2 group buys. Not sure where they are to dig it up though.. let me look

Here is the dyno results. Baseline is with berk hfc and then catback is added on the next dyno.

baseline(with hfc)
1:280.80hp 244.28tq
2:284.15hp 243.22tq
3:281.29hp 248.50tq

cbe with hfc
296.90hp 250.91tq

Any links to the Stillen exhaust/berk hfc dyno results?

Check Semtex's album.

doesn't Semtex have a freak of a car though? Took to mods really strong? May sway things a lot without knowing compared to the norm.

Nice vid. You def. need to find another Z with an F.I. exhaust!

Nothing i've read has shown the car to be a freak, his dyno results are right on par with mine with similar mods. His dyno charts are legit with results that can be expected with each mod.

Gotcha, I just remember reading someplace about his car. Never doubted his results though.

Lets hear some input Semtex, i know you're lurking around somewhere...

:iagree: 100%

Mad Props to Spearfish and JB1 for putting this vid together...Awesome job guys.....
