ABSOLUTELY! :withstupid:

:lurk:

 

:eek: :lol:

 

:iagree: This is a great thread. Leave off the locks and lets dyno. :thumbs:

 

:lurk:

Any of you guys who recently put on your headers going to hit a dyno anytime soon? :D I'm interested in seeing the gains and if charts are possible even better.

 

I'm having my tranny/converter replaced next week. Once it's in and I've gone through the break-in period I will do a baseline dyno, install the headers, and run a post-install dyno.

 

I need to wait for a club day at the dyno, save some $$$.

 

Comment: You do not need 3" pipes on a stock motor.

 

:yesnod: :iagree: :yesnod:

How are there no numbers yet for this setup? Every time somebody asks LGM for a # they post a dynograph. How come Dynatech doesn't have #'s for their own system?

 

The LG headers have been on the market for a number of months now and there are several people alreadt running the LG headers. The Dynatech setup is new to the market and there are fewer to report Dyno numbers at this point.

I will have before/after dyno graphs for the Dynatech headers within the next two weeks.

 

My question is why doesn't Dynatech have at least their own dyno #s. To me they are a new challenger to the C5 market and they write a long letter like that and have no numbers or graph after all those fancy words.

Tuners/Manufacturers produces their own numbers and dyno charts on their products as including LGM. I would never want to be a guinea pig for a new product.

Hope the numbers turn out well. I am looking forward to see what these do as I want to eventually put on LT on my Z and have been reading all these header posts to see whose system is best.

Quote{As mentioned, the initial design process was around 8 weeks. It takes an additional 4 weeks to write the bills of material, quality control manuals and procedures, inspection procedures, installation instructions, etc. Copying someone else's design, although quicker to initial production, is the wrong strategy and not something we did in this case. There is no way we could risk copying another design, not knowing where the problem fit areas exist, where the tightest tolerances exist, whether the piece we would be copying actually fit, etc. We have learned this the hard way over the years when producing headers for other companies to their specifications. When dealing with the run sizes we produce and the investment associated with the inventory it would make no sense to stake that much money on another company's design. Any real manufacturing company understands this.}End Quote

Even if they did provide a graph i wouldn't go by it or any other vendor's dyno graphs for any of their products because they are almost always a little inflated. I'd like to see some real before and after dynos of someones car who purchased this set up.

And by the way nice to see someone revived this thread from the 2nd or so page i was afraid it was going to die i was about to bump it up. For some mysterious reason these headers intrest me.

These interest me as well. But I am thinking that the LGMs and Kooks have more real world data at this point. Still partial to the LGMs though. But I am extra cautious as my setup will probably benefit very litlle from any header system, stock Z.

 

I personally think that there is more to a header system then just the final peak HP. I am looking for area under the curve, ease of installation, minimal disruption to my existing OBD II system (keeping all O2 sensors) and stainless steel construction. I think the FLP's meet all but the SS construction. LGM meets most of the criteria, not sure about Kooks and the Dynatech appears to meet most of the criteria as well. I am willing to give up a few HP to meet my other requirements, but that is a trade-off I am willing to make, others may not and if you are from a state where emissions are not an issue, you have even more flexibility and choices. In the end, I will weigh all of these and make a decision. Hopefully, that will be this summer.

I agree, and Stainless Works has a stainless setup, although I don't see much written about them anymore and don't know why they fell out of favor after the Kooks came on the market :confused:

I'd love for someone to find out, and post, the lengths of the primaries on the Kooks, LGMs, and Dynatechs with the variance between shortest pipe and longest pipe on each single 4 tube set. I'm leaning towards the one with the most equal length so I can tune the engine easier after an install.

 

:eek: :iagree: :thumbs: I been looking at the cat's" but now I think I will go for the whole settup! :yesnod: :cheers:

 

I heard Corvette Fever only got 15 HP, anyone get the May issue yet?

 

That was through the OE mufflers (15.6). They took them off and got 20HP and 21lb-ft over the stock system. This was on an automatic and they averaged all the runs out.

 

Did they do any tuning?

 

They didn't mention any tuning.
