We are a performance shop in the midwest and we are testing various short tube headers and long tube headers. The reason for this post is to get anyones imput on others that we should test side by side. As of today we have these short tube headers-b&b, bassani, and jba's. On the long tube side we are testing the tpis, tts, and breathless's. If you believe we should test others please drop a reply. We are testing these on a c-5 with a intake on it. No heads or cam work done. And we are also testing on our own Z06 test car. It also has a intake and no head or cam work. The reason that we are doing this is to accurately show gains from our dynojet chassis dyno to people that have questions on headers vs headers.
Thankyou for your imput

 

Tech, GREAT.......it's about, no it's PAST time for this.........if i might make a suggestion, please do several INTAKE tests, with out headers, and then with........you will have covered the WHOLE 9 yards IF you do this..........

Hey Now:
Very good idea. Will be waiting the results!!! :cheers:

 

How about some LT Headers from LG Motorsports!!! :yesnod:

 

Looking forward to the results. I'm guessing there wont be too much varience in gains. Where are you guys located?

Greg

 

Sounds like a great idea for many of us are considering this mod upgrade... Please post results as you go... Thanks...

Nick :cool:

 

I look forward to your results, and hope you will be rewarded with business to back up your efforts. :cheers:

 

Thanks for doing this. It will be very helpful to the C5 community.

:cool:

 

Is that Breathless's new Step Header? I would like to know the numbers on that.

Thank you very much. :cheers: :seeya

 

I would love to see the results on the Bellanger.
Thank Yoy.Dave

 

In response to the LG headers, we will contact LG Motorsports this week on their header and maybe add to our test. As for the Belanger we will also consider adding this header. We just returned from PRI and are getting everything lined up for the tests. We do have intentions of doing an intake vs intake comparison also, but for now we are concentrating on the exhaust work. The Breathless header is the step header. Don't know if we will be able to get our hands on the LG or Belanger but will try. Thanks for the imput guys. Hopefully this information from this will benefit everyone.

 

Hey Tech Tuner, how bout adding Belanger long tubes to your test as well. Have been some claims on the forum that they may give the best gains for a basically stock engine. I've seen them advertised by Nate at Xtreme Motorsports. Thanks !

 

Good idea and can't wait for the results.

What else does your shop do?

* Original Stage II heads from New Dog, Old Tricks; GMHTP May/July 2000

** Latest revision.

Info originally from Chris Endres

 

Please include the DRM Longtube headers :)

 

I also am looking forward to this since my next big mod will be
LT headers. most likely TTS or Balangers. Great idea!

 

:cool: I would like to see what I am missing in power with my B&B's. I do like them though, especially since they just bolt on :)

 

I would like to see how the LONG TUBE headers compare to the new SLP headers coming out next month. They sure "looked" good against the other two brands they had in house.

 

How about the Hookers and the BBKs?
