HFC Cel Info

BerkTech · 06-25-2009, 04:07 PM

We've gotten a lot of questions lately about our HFC's and test pipes causing CEL lights to come on. This is an older thread from MyG37 but it should help answer some of your questions or concerns.

how much wheel hp and tq do they give on a stillen exhaust ?

Junior370z · 06-26-2009, 12:01 AM

I've put about 800 miles on my Berk HFC's and have not had any cels. (knock on wood) I've been diconnecting the negative side of the battery because of installs of some form or another. I don't know if that helps keep the cel from coming on though, maybe just coincident.

We havn't dynoed our HFC's with a Stillen exhaust but we have seen gains of up to 18whp with our HFC's on a stock exhaust. If anyone else on this forum has dynoed there car with this set up please chime in

I have Berk HFC's & Stillen Exhaust & Intake....I'm going back to Altered Atmosphere next Friday (July 3rd) and having a dyno done. I'll post up the results.

My Berk HFCs have been on for about 5,500 miles so far (with Stillen headers in front of them to boot) without throwing any CEL.

Awesome! how do you like the set up so far?

M.Bonanni · 06-26-2009, 04:01 PM

I have had the Berk HFCs on for almost 5000 miles as well without a CEL.

It's great! I've had quite a few double takes when I pass.....that's always fun! I can feel the difference as well. It's made me not want to get out of the drivers seat.....I just want to keep driving past work!

(Then again, most people would problably still want to go past work even without the mod's!)

Any members on here with the test pipe throw cels, as I am about to put them on my car in the next couple of weeks and wonder if I could just go with the non-fouler (not sure on spelling) method right away to stop from throwing cels??

DannyGT · 06-26-2009, 07:46 PM

I had the test pipes for a ~2-3k miles with no CEL! (CEL was on initially (~150miles) but cleared itself and never came back on) That was great!

ssqpolo · 06-26-2009, 09:29 PM

i have berk test pipes and my service engine light came on after 600 miles. then i cleared it and after hard driving one random day it came back on. sooo i dunno. i just clear it with my 200 dollar code reader i bought from autozone. so its not a problem for me.

BerkTech · 06-27-2009, 03:28 PM

We have seen mixed results with the test pipes... some cars throw a cell and some don't... but with our HFC's 85% of the cars don't throw a cell

Went to Altered Atmosphere again today. It's been about 2 weeks since I had the Berk HFC's and Stillen Dual Exhaust & Intake installed. Here are the two dynos:

Pure Stock Dyno performed on 13 June 09:

Dyno performed on 01 July 09 (includes Berk HFC's, Stillen Dual Exhaust & Intake):

I'm not tech saavy at all....so is this the expected increase or not enough or more?

That second one doesn't look right. There's no graph. Like there are no lines.
