Your ACR did what, 602/583 with Gen V intake, Mopar PCM, ARH headers, no cats and stock 2.5 exhaust?
So supposedly Ralph's car differs in he is running high flow cats and bigger exhaust?

The focus shouldn't be on the 10.8, it should be on the 133 mph with minimal mods. That is moving! That car will go 10.50s with a good launch. Definitely supercar territory.
Pretty cool that the CEO has the record run. Has that ever happened before? With any brand? Congrats, Ralph. Gives me a reason to go race again.

That is great. Awesome to see that the guy running the show is so passionate about the cars he makes.
Not likely new, just due to cost (the pragmatist in me), but I will say that the overall driving experience is just as fun as the ACR in the one I drove in with Graham Henckel while not having ANY rattles, vibrations, or misc noises that the Gen 4 has and just feeling more subjectively "solid"all the while being wrapped in an interior that is every bit as nice as an R8, Porsche Turbo S. The car is awesome. They had a Blue/White stripes ACR there parked next to the Gen 5's and to me the car is still just slightly more aggressive looking but the Gen 5 really feels that much better put together. It really is a great car....I'm just partial to the big wing on the back! I would recommend those who haven't driven the Gen 5 to do so before passing final judgement.
Anyone who knows how to launch, can beat the factory"Launch Control". In Ralph's case I believe he did use it and that is not a knock on his driving, look at the reaction time, that tells me it was not a driver controlled launch. A 1.8 is not bad, but, it is not a great 60' time. With his mph, a set of sticky tires should put the Gen 5 in the 1.5-1.6 sec region with an ET close to 10.3-10.5.
Does anyone know what strip was used or what the DA was?

Stock Gen IVs dyno around 535rwhp SAE regularly. Since the Gen V has 40 crank hp more, I am not sure what to make of a dyno with an ECU at 576rwhp. It would be great to see dynos on representative, non-special/non-ringer, Gen Vs with just ECU, Stock CATS and CAT-back Exhaust such as Corsa. This combination has a chance of passing emissions testing virtually everywhere.
Also, I am with Nine Ball in that while the ETA is great, the mph is truly impressive.
Do we know what headers Ralph's car was running?

Despite the gen 5 having 40 more hp than the gen 4 from what I've seen they dyno very very close. I dynod last year and got 529, a gen 4 with (I think) the back cats removed dynod 535. I now know my engine then had some issues and that certainly contributed. If I can get the off-road PCM installed before May 31 I'll be able to dyno it with an otherwise completely stock car.
Yes sir the difference between my 602 and his 598 was me with no cats and stock cat back. Ralph was running cats and I thought a Corsa or Balenger catback.
He said it was 44 degrees out so I think the DA was decent.
My Gen IV ACR made 562 RWHP SAE stock. Even though Gen V's make more power they run 3.55's wich usually eats 10rwhp on the dyno even though it improves the cars acceleration.
Basically with similar mods the Gen IV will make 15rwhp less, only because the new ECU looks like its making a real correction over the stock tune.
I thought dyno runs were always run in 4th gear where the ratio is 1 to 1 so that gea ring would not be a factor? Is this not the case?
I agree, but it's not ground breaking.
Throw good headers, exhaust and a tune on a Gen V and I would expect them to be running 133 mph on a cold day like that.
Same goes for a Gen IV.
Toss headers, exhaust tune and a Gen V intake on a Gen IV and I would expect the same MPH.
Revolution ran 10.8@133 in his 2009 with headers, exhaust and 3.55 gears.
Any stock Gen IV or V should be trapping high 120s with a good driver on a good day.
It is hilarious, we are debating (my car is better than your car) hp differences of less then 10 hp from different dynos.
None of that sh.t matters. It is all about 1/4 mile mph at a given DA. Anyone can manipulate dyno numbers by 5 % merely with smoothing and correction factors.
Lastly, I believe the Gen4 133 mph was with a DA of -2500.

Agree, didn't say or mean to imply that it was groundbreaking. The only thing unique about what Ralph's Gen V has done so far is that it did it with cats. I don't think revolution runs cats.
My ACR at 615 RWHP SAE was trapping 129 on my V Box in 70 degree weather. With good conditions and the wing removed I felt like it was a low to mod 130's car.

I agree, pretty silly just glad to see the new cars running like they should.
That Voodoo was bad asp too. Does he still have it?
Speaking of his Gen V, I just stumbled across this video for the first time.
Is this stock exhaust? What a cool dude!
LOL at Andy and the multiple mentions of cats. You a crazy cat lady? Haha. High flow dual 3" cats were only worth 6 rwhp on my Z06, which was at 619 rwhp. Not really a big deal at this power level. They start to become restrictions well above 700 rwhp, when they begin to melt.
