As title says looking for a dyno sheet (overlay even better) of longtubes on a .1RS W/Dundons vs .2RS W/Dundons.

Thanks!

INDEPENDENT would be awesome. Not from one of the fanboys but an independent customer. Baseline and the 2 cars mentioned would be great. Also would be great to see other companies on the same day/same dyne. I bet here're all within a margin of error.

Same dyno and similar conditions important to gain anything from it. Dundon has all of this. They seem to be very transparent. I have yet to see a post from an unsatisfied customer. They also back their product with a guilt free return policy. Look on their website. If the graph isn't available, email Jaime and he will provide what he can.

People have been trying to shoot down Dundon for some time now and I think they have earned the right as some of the best made/performing headers out there. Good to also see that JCR has a nice product, as well, to compete with them

And i have no skin in the game.

If I am going to go with headers it will certainly be the Dundon Sport headers w/Catts

Has Dundon released on their dyno a .1rs with their headers and also a .2rs on their dyno?

Basically I'm curious the delta between a dundon header'd .1rs and .2rs

I'd be happy to facilitate, I know Adam LZ now has them on his local .2 ( Catted version ) and Matt has a .1 with the non-catted version but should be switching to catted version soon. Will be happy to supply the dyno if these guys have time to strap them both down on the same day.

Have no skin in this game but have been really impressed based on the results I saw first hand with Matt's .1 when he originally bolted them on.

I guess for an accurate reading they would need to be done on the same dyno?

[QUOTE=Jimmy-D;15716004]Jimmy,
I have a set of Dundon catted headers on the way for my .2 GT3. I'll post my thoughts on them after the install.

Yes, to not get into the correction factor debate, etc. It's up to them to see if they want to do this, I'm just offering up the dyno.

We have a Linked Dynojet 424 Lc2 here at Titan, we've had it calibrated quite well from dynojet to ensure we can measure the big HP (had a few 1500-1800hp cars on it).

I had my supercharged r8 on there about a month and a half ago. Now puttingpun a bigger supercharger and meth lol. Do you have any. .1rs or .2rs dynos o there you can share? I should bring my 997 gt3 sharkwerks 3.9 stroker on over and see how it does lol

Well for the 991.1 rs JCR (a competitor) did a dyno on their 991.1 rs, so that graphic is as unbiased as it could be. The 991.2 rs is an harder one. I would bet that the youtuber mentioned above will dyno his car, givrn how in he is in the tuning world.
Maybe is just a matter of them figuring out a date to go on a dyno with both cars. Seems the easiest most likely to happen option.

In a week or two I'll be able to provide real world results of rolling acceleration runs for my .1 RS w/ dundon street headers against my buddy's .2 RS stock (for now).

Matts .1 Dundon test was done our dyno (plus about 5-10 other exhaust options, the Dundon results blew me away and I'm normally the first person to look the other way if I smell bull****.

On the 3.9..... Please don't...... having a house 4.0 car has made me struggle enough with my 3.6L GT3 hahah (it would be fun though).
