I haven't talked to Berk since before the holidays.

Sounds good, just getting excited. :D

You and me both brother.

Dyno Test for Cold air intakes
 

I think that the data supplied for dyno test is suspect to me. After 23 years in aero space and calibrating orifice plates, venturis and other flow devices. the outside ambient air temperature or the air getting to the filter is the controlling factor in how much hp is to be gained. The colder the outside air temperature air density increases so volume increases and greater HP gains.
The hotter the ouside air temp density decreases and less HP gains. Radiated heat from the engine compartment has to play aprt in this also. The tube have to stay at least the same as the inlet air From what I gather most of the testing has been done in California and I have not seen a lot of data. I would like to see some dyno testing here in Florida. Then some road testing on the highway and see what the cai inlet temps are and temps after mass flow meter especially when your sucking in road temps that get to 120degf. A 30deg swing in ambient temp can really effect the out come. I know that I may be nit picking but I truly believe that HP gains are going to be erratic from one part of the country to the other. 1 don't have a clue as to what that would be but I would guess that it could be as much as a 5HP spread.

What is does air temp at the throttle body need to be to produce 18 hp gains consistantly?

Let me kown if I am on the wrong track with any thing or has my engineering been getting in the way and just old nit picking. Working on Jet engines we were always trying to squeeze the most thrust at any conditions. Wether it was at sea level or altitude.

What does that have to do with the group buy for the Berk exhaust system, Billy?

Considering this is a thread for an exhaust, ya I'd say you are on the "wrong track". :gtfo2:

:iagree::wtf2:

Need update

Sorry I posted it in the wrong area, my bad.

:iagree:

Awww. I was thinking, "yes an update." Oh well.

There is another thread that has updates:

Bump!

Hey Berk it's Mid January what gives??? :mad:

Company they outsourced their tips to apparently didnt get em right still.

I got a PM from Mike yesterday. For the frist GB shipping date is Mid February. The people who are paid in full will be shipped first. :twocents: :twocents:

Yep, glad I paid in full the first day I paid, do not have to worry about. :D

:excited:

I drove into a parking garage and I could not hear my exhaust. :( I was next to a Aston Martin and I could hear his exhaust as he slowly drove away. Now I'm looking Forward to get my exhaust soon.

Same here, my car is fully broken in (12k) and I can definitely tell the car is screaming to be opened up but those screams are muffled by such a weak exhaust systems. :(

So would you guys say that berk makes a way better product then stillen or is pretty much the same?

BERK - What is this exhaust going to retail for? I may be looking to buy come this summer or spring (hopefully). Also, it might be helpful to update your website with the new exhaust system. ;)

No worries by the time Berk starts to ship the exhaust it will be spring, make that summer.

No one except Minicobra has the exhaust to tell you. The HFC are all pretty much equivalent though.

Almost all exhaust systems are personal preference...

Right, but then that would mean that the non-GB'ers will have to wait longer to purchase (at retail price) because the first couple batches will be going to the GB'ers.

So, who knows when the rest of the public can purchase and at what price?

Well I was the first to get in on the GB an I can tell you I have no idea when They will ship.

The first batch is due to arrive at Berk next week and then Berk will promptly start doing their in-house adjustments to the tip alignment and start sending them out. The first batch will cover almost everyone on both GBs. The second batch, will cover the last few GB2 buyers and have plenty left over for dealers stock orders and customer orders. That batch is due to arrive in April.

Thanks for the update Mike, the last update direct from Berk said end off February. I guess once again it got moved back. What can you do but wait........

IMHO, I'd rather see a company delay something repeatedly than to rush something out the door. It was obvious they had issues with the company making their tips - they didnt hide it. So rather than release the product with issues, they are ensuring we are getting a quality product the first time. Not the 2nd or 3rd...

These exhaust should start shipping end of February just as we last said. They get the systems third week in February and they will immediately start making their adjustments and sending them out.

sweet, I'm number 2 on the list !

I agree Mighty, but don't you think Berk should have choose a company that would build to there spec, an QC standards? Not saying they took the cheaper way about it.

With that said ,who's to say that the test part wasn't just what Berk wanted. Just they couldn't do it on a mass production base. Either way I'm glad I'll own the system, even If I have to wait for it. I'll know there won't be any fittment problems.

Easy now. It's a couple of weeks away. Time to celebrate! :happynewyear:

That is to long, I want it now.

:mad::mad::mad::mad:
I want my exhaust.

Have you paid in full yet :ughdance: I have :tup:

I paid in full the day my name was on the list. :D

ROFL imma :owned:
