Currenly i have HFC's w/stock and love it.It's faster and deeper than stock

it's help keeping the luxury-Quiet but more HP gain.

My concern with Stillen was too loud inside the carbin.My next projext will be

True Dial H-Pipe.Will post more VDO. GL

 

nice job. i love that berk hfc

 

awesome vidz, but hey can you post a video of a cold start up with just the berk hfc..im very interested in just putting on the berk hfc on my stock car, but i'd like some more vidz, and a vid of the car starting up would be great..

Wow... great videos! I really like the sound of the Berks with the stock exhaust. I think that is the route I'm gonna take... at least until someone comes out with a better sounding / quieter cat back for our cars. Thanks for helping with my decision, man!

 

Oh yeah... and I'm glad to hear you like your Berks... everyone around here has the FI HFC's, but I really like the Berks and they are only about 15 miles from my huse, so I can just pick them up. Quick question... do you get any CEL's with your Berks installed?

 

I'd like to know that too. FI could not guarantee that I wouldn't get a CEL, which sours the sale for me.

 

Those sound really good. Thanks for the videos!

Are there any gains to be had from just running the HFC or is purely sound? I searched around and couldn't find anything so I guess the answer is minimal to none?

 

i also have the Berk HFC with stock exhaust.

you should NOT throw a CEL with these HFCs. i didn't at least, and i don't think i have heard of anyone that has. they come with adapters built into them to move the sensor away from the increased air flow, its pretty cool you'll see how it works once u get the HFCs in your hand.


the HFC do get you pretty good gains. i've seen an independent dyno that got almost 10whp AND 10wtq from them. i'm not sure what i got, i didn't dyno it, but i can definitely feel that power was increased. and it makes your exhaust sound meaner too..

 

Thanks for the info Earth0, you got PMED!

 

Nice videos and thanks for sharing, I can't hear any noticeable difference between the Berk's and FI HFCs

 

anybody have a reputable place to buy these from? Maybe Riverside can order them?

 

Yeah, 6 - 8 HP gains is pretty common... 10 HP is very good, and I've even seen guys get as much as 12 HP gains just from the HFC's alone. And, if you combine that with the TechnoSquare or RevUP reflash, then those gains can be even greater. I'm hoping to get the Berks sometime next month and then I'm gonna go with the new RevUP reflash software.

 

I plan to get mine directly from Berk, since they have them in-stock and ready to ship. Just e-mail Bryan over there at info@berktechnology.com. Tell him that Adrian sent you.

 

I really want to see your car 2G, ugh, mines in the shop, i come home from a 30 day trip was with my car for a day then it's in the shop hahaha, it's gonna cost me 5k to fix it.
