New Exhaust for the Six - It's LOUD, What? What??? WHAT?????? Options

[drew365]

It's actually fairly tedious to take out all the hex screws, separate and count the disks and put it back together. Probably takes a good 20 to 30 minutes. Not something I want to do too often at the track. If 6 disks drops my power off too much I'll try 10 on Sunday but that will be it.

Frank Beck in AZ is now making a trick 914-6 race exhaust that is interesting too and supposedly makes huge power...but I suspect it is north of $2 large

Any thing that Frank is making is 100% CRAP!!!!!!!!!! (IMG:style_emoticons/default/bs.gif)

Tim:
I notice you've included a balance tube in your set up.
I've never gotten a straight answer as to whether or not
this is a good thing. Logic says yes, but my logic has no dyno attached (IMG:style_emoticons/default/biggrin.gif)

Comparitive dyno work that I've seen shows the Triad muffler set-up (with a balance tube) to be at the high end of the HP charts, while Super Traps.....aren't. (IMG:style_emoticons/default/confused24.gif)

I haven't noticed any HP loss going from the Triad that was on the car to the dual Supertrapp setup without balance tube - but this is measured with my super sensitive and carefully calibrated butt dyno. Seriousy, the car doesn't not feel any different - just louder.

I hope to get the car on the dyno towards the end of winter once I get it back together after the paint job. I'm in the process of stripping it down to go to the body man right now. I'll be able to give a more definitive analysis then. (IMG:style_emoticons/default/biggrin.gif)

limited knowelge but just had mine dyno'd and they went from a balanced exhaust , a Y with one race muffler , to two separate mufflers. They got a higher rating with the new exhaust.

My knowledge on the subject is limited to this:

In my experience....the 4s NEED the cross over, while the sixes "like" it....but not needed. I have noticed that a cross on a six lessens backfires and quiets the exhaust....

I just wanted to say hello. I'm very excited to finally post. I own an awesome original 914-6. It's been featured in several magazines before we purchased it. It was made by the owner of Kinesis wheels and sports one-of-a-kind red wheels. I'll post some pictures. It has a 3.2 L 911 engine making around 250 hp. It has a custom exhaust by Midwest Eurosport that sounds amazing. We haven't taken the engine fully apart, so we're not exactly sure what mods were done in there. It has factory flares, koni shocks, AJ racing seats, Simpson harnesses. It is an great car. If I could post a video of it, that would be very cool, but I haven't figured out how. Hope you enjoy it as much as I do.
I will try to see if I have any pics of the exhaust around.

I haven't run them with only 6 so I hope I didn't go too far.

FWIW: I have a friend that has a 2.2-6 with S cam. He runs a single supertrapp.

His engine should be around 240hp at the crank.

On the chassis dyno with about 4 discs it pulled about 106 at the rear wheel.

He added about 8 discs to total 12, and it pulled 128hp at the rear wheel (which would equate to about 140 at the crank).

Interestingly, it didn't alter his torque much either way.

Apparently, you can really choke down your power with too few discs.

ben14142001,

welcome...ah yes, I have taken numerous pictures of that car....you need to post more !!!!!!!

one of the nicest 914s I ever seen (IMG:style_emoticons/default/wub.gif)

Are you serious about your statement, as I do not really know the man (met him once for about 15 seconds) but he has prepped/built some of the nicest 914-6 race cars I've ever seen. These are 2.0 & 2.5 VARA cars that run low 1:30's at Willow Springs; which is a very solid time for a >3.0L 911.

Not that it matters much to me either way as I am not about to spring for a $3000 exhaust setup anytime soon...

[Mike9142.0]

I worked for him for a year and a half and have seen the he works.

[campbellcj]

FWIW this is the 911 version of the Beck exhaust I mentioned... sorry to hear you had a bad experience working for him but this exhaust does not look/sound like "junk" to me at this point based on the limited owner feedback I've heard

I wonder who makes it for him?

I saw this header system while browsing the Gunnar Racing site. It's for a 904 six restoration.
