Go do a search on the current tuned GT350s with AR headers. You keep going back to Voodoos results which aren't even finalized. The 2-3 I've see so far have all been in the same range.
Well what's more impressive is the ARH made more then kooks either way. Kooks are a 1.75-1.875 step header, ARH are straight 1.875.
So you don't understand the concept of SAE correction factor being a lower # than STD? -and how looking at an SAE baseline and STD post change is highly flawwed and results in an artificially high Delta/difference? If not, there's really nothing more to discuss.
Yes I know the difference between std and sae. But even when you were shown other stock tune header dyno pulls that shown 29hp pulls you still want to argue the facts.
Why don't you do this for all of us. Take your own gt350, buy a set of kooks and a set of ARH and do your own dyno pulls in 2 days. Do base line pulls on the stock system stock tune, then do one brand one day and the other brand the second day, all on stock tune. That's about as accurate as you'll get. It's been proven so far that the ARH system on at least 3 cars makes more hp. It seem your hell bent on proving that one system is better then the other yet you provide no facts. To date we have 1 kooks car and at least 3 cars with ARH. And the numbers with the ARH have proven higher. Even on a stock tune with the ARH I was running lean. Are you aware that others that have done dyno pulls on the voodoo have also reported of a lean afr? Say for example a gt350 with a tune on stock exhaust with say a JLT did a dyno pull and made 470rwhp then installed kooks or ARH and pulled 500rwhp. Will you still say it's not a 30hp increase because it's not stock anymore? Once headers are on its no longer stock anyhow. On the same day i did the ARH dyno pulls I made 484 with the lean stock tune. With the Lund lean tune I made 511rwhp lifting off at 6000 rpm. Since that day I've data logged and have added fuel and timing. When I get the chance to go back to Watson I'll report my results. But next time it won't be on 93 it'll be Sunoco 260GT 100 octane. On another forum they have shown that with 91 made 429.77 then with 93 made 440.42 then Sunoco 260 gtx 98 octane made 456.48 on "stock ford tune". It seems the stock tune is adding timing when it detects higher octane fuel.
Just don't respond anymore.. Not worth the time.
You're about the science, not the show-boating, and I like it - just for the record. ^^All this other BS wouldn't fly on corner-carvers, for example - the forum members there ONLY do science.
I guess you're the only person who 'gets it'. There seems to be a ton of delusional fanboys on this thread who don't. I really don't care which brand is better, I just care about proper comparisons and test procedures. So far there is only 1 Kooks data point and a bunch of ARH that show a greater power increase, even when analyzed properly. Pointing out the fact that all ARH's so far have made more than Kooks, and Voodoo's own test conditions were the most consistent thus-far (reason for wanting to see a proper comparison) makes me anti-ARH? :headbonk:
