That might explain the difference.

(Remember I'm knew to all this) |
6 speed?
If so lower gear ratio so maybe less spool. |

You weren't in the 1:1 gear, Ed was.
I'm fuzzy on how the final drive affects things on the dyno, but i do know that every time i've been on the dyno, the operator ignores the final drive and sticks it in the 1:1 gear. |
AFAIK 1:1 gear means the input shaft is directly connected to the output shaft, therefore no losses from the countershaft.
Also from BBundy and others we know that 4th gear is one of if not the weakest in the 6 speed (or at least the most likely to break out on track). |
Yeah, I wouldn't suggest a bunch of 4th gear 6-speed dyno pulls with a high powered car. But afaik, 5th would only make the graph look better.

that second pull in the video is 4th gear? gets to redline in like 3 seconds.

I could see it if the dyno wasn't loading up like... at all. But that pull is exactly why his graph looks the way it does. |
Brain's talking about Jeff's video, not his dyno graph.

needs more drama!

If that's the case, the graph doesn't surprise me in the slightest. |
I'll go over the videos later, but I am 100% sure all pulls done on the graph were in 4th gear.
Maybe I just picked an AFR tuning clip and mistook it for the 4th gear pull in my tired state. I can understand your confusion but I have no reason to lie as I have nothing to prove/nor care to prove beyond my own enjoyment driving the car. Anything I post in the thread is just my enthusiasm for having fun with this thing. |
Edit: Dur I should have read ALL the responses. So the answer to my ninja-edited question is maybe.
Although would it make a difference that mine was 5th gear with 4.10 rear end and his was 4th gear but with 3.63 rear end? |
^^ good point. There is about a 12mph difference at 6800rpm between 4th (3.6 gears) and 5th (4.1 gears) though. That IS something.

Hmmm I'm interested in what a different Dyno would report then. It certainly doesn't feel like it spools that late/delivers power that slowly.
What are the right questions to ask the tuner to find the answers we are obviously lacking? Could my EBC to EWG routing have affected the spool? If it was truly that slow on power you'd think I'd be able to feel it compared to my 2860rs turbo. |
