Stillen Exhaust with Berk HFCs

semtex · 03-23-2009, 08:35 AM

What don't you like? You realize this is a Dyno Dynamics, right? They come in lower than even Mustang Dynos. 291.7 on a Dyno Dynamics = approx. 344 on a DynoJet!

Give this thread a read if you haven't seen it yet:

Semtex,

These numbers are sweet. I'm expecting my cats tomorrow and will have them and the Stillen exhaust installed sometime this week. I'm looking around Austin for a dyno to hopefully get before and after numbers on the same car.

Cool! Pls post your before/after results to this thread, if you don't mind. As more people get this combo, it'd be nice if we can use this thread to compare everyone's experiences and results. I know that thus far, this thread has been all about my car only, but that's just because I'm the first one on this forum to try this combo. My intent is for this thread to be open for everyone who tries this combo to post their impressions and results.

M.Bonanni · 03-23-2009, 07:22 PM

Those are some impressive numbers! Even though its not exactly a direct comparison, I am glad that these results back up my results with just the Berk HFCs!

Let me know what you find. I live in Austin and am picking up my Z tomorrow!

Well, my YouTube video is drawing some skepticism judging from the comments left there. It kinda irritates me when people imply that I'm being dishonest just because they're not used to seeing such significant gains. I'm just to sharing my results for the benefit of the community, after all. I invited them to join the forum if they want to discuss.

Interesting numbers.

Semtex, do you have any plans on racing? I'm curious as to what your times would be with those mods

JohnnyBgood · 03-24-2009, 09:14 AM

Not having much luck finding a place that will do the dyno for me, and my install is scheduled for Thursday. We'll see what happens.

theDreamer · 03-24-2009, 10:29 AM

Semtex, thanks for all the reports.

ChrisSlicks · 03-24-2009, 02:28 PM

I'm impressed by the gains. Looking forward to seeing the intake results on top.

bullitt5897 · 03-24-2009, 03:37 PM

hey Ben I bet sharif would let us dyno again but this time we would have to wash the entire GTR! LOL hehehe

semtex · 03-24-2009, 04:29 PM

Yeah I sent him an email today, actually. The received the G3 intakes today and should have them on either tonight or tomorrow, so I want to do another dyno to see what gains they yield.

RCZ · 03-24-2009, 04:42 PM

You got the intakes too? Cool. Let us know! I'm calling 302.4hp.
