It was hard to have a conversation with the missus in the passenger seat at anything over 50-60 mph, so they had to go.

will definitely look into these. thanks!

Congrats!!! I bet she feels amazing! Can you share the graph?
Would love to see the torque and boost curves.

I assume boost is dropping on the top end a little?

Very nice, congrats. Just wait till you drive it at sea level LOL. It’s a whole different beast without the altitude.

not letting me show the image, think the forum is weird for me on my macbook. But the Before numbers were 626whp/702tq afterwards, same dyno, 740whp unknown tq as that part wasn't working properly. I'm assuming tq is high as shit now.

Honestly can't get this to work, if anyone wants to dm me we can swap phone numbers and maybe you guys can get it to upload properly?

That is one weird dyno graph... 740 hp @ 3450 rpm? Where is the rest of the rev range? Did the pull end as low at 130-ish mph, what gear was used? The correction factor is very high, too, but that's probably because of altitude...

I agree the Nitto NT555RIIs are a great tire, one of the best mods I've done tbh.

Yeah not sure I've seen a graph that has HP vs MPH ever..normally that's RPM (but we could convert that, easily done). Agreed that the peak HP at 3450 is VERY odd, that should be north of 6000 RPM. Most of these cars hit well over 140 MPH on the dyno as well (indicated speed on the speedometer) and I know that with automatics that typically the 1:1 gear ratio (6th or 7th?) generates too high a MPH for the dyno to operate safely.

SJFGTO · 10-27-2022, 06:49 AM

I like the fact that the engine stays north of 700 for a spell, definitely not peaky, which is a good thing. The rpm range, if I am reading it right, is weird. I’d like to see it on a traditional dyno chart. Congrats on a great build though!

RobZL1 · 10-27-2022, 07:35 AM

It's not actually at 3450rpm. Sounds like the rpm signal wasn't good, hence the mph on the x-axis instead of rpm. It's fairly common to see mph instead of rpm, especially at dyno days where the operator/shop doesn't want to take the time to hook up the signal to every car.

Correction definitely cuz of altitude lol. And the main thing for me is that I know the same dyno was used in both before and after. Whatever settings they used the first time were the same this time. 626 -> 740.
