Default On the Dyno Today

I just got to the shop this morning and they're pulling my Z onto the dyno. I had 389rwhp a week ago but my a/f ratio is running rich at 9.5/1. They'll get that dialed in and I'm anxious to see what the final numbers will be. I expect to have pics and video up later today.

John's got the a/f ratio corrected to 12.3/1. The car is now putting down 411rwhp and he hasn't even played with the timing yet.

Now it only needs to get louder. Remember the one you were plugging your ears for when it was on the dyno not everyone likes to scare people. Nice numbers and can't wait to see the final results.

Nice numbers already from the car - looking forward to seeing what it ends up being after all the tweaking is done.

I didn't plug my ears today.

John was able to squeak another 3 ponies out of by adjusting the timing but it also introduced a bit of knocking into the mix. We chatted about it for a few minutes and wound up having him go back to where it had been. I wound up with 411rwhp and 409 lbs/ft torque. Not bad for a few hours and less than $400.

I'll edit a video and post it up here in a bit.

This is a bolt on car?

Edit: very impressive. Healthy car for sure.

Plans for a cam?

Yes. I've got a Hurricane CAI, FAST Intake, LG Long Tubes and X-pipe w/Borla Stinger Cat-back + today's dyno tune.

Edit:

We did discuss a heads/cam install today. If I do pull the trigger on that it wouldn't be any time soon.

Here's a quick video of my Z on the dyno today.

I took video of several pulls but they're all pretty much the same.

Enjoy.
