not sure, it was one of the tuning runs so it could have been an overly rich spot or sudden timing decrease, but my guess is that it could have been the end of the run or rev limiter since the smoke didn't come out from under the car meaning that since it has open dumps the wastegates were probably closed.

Given the video, it appears the car is still pulling pretty hard and continues to after the smoke puff, so it shouldn't be the rev-limiter.

Either way...man, I want to find out BAD if the 7AT can hang with it...lol.

Then it'd only be a matter of rounding up the money - lol.

What is the puff of smoke before the rev limiter kicks in?

Unburnt fuel I'm guessing since these vehicles will be tuned to run a tad on the rich side.

westpak

yeap as simple a that

I guess some have never seen a turbo car, an aftermarket one at that, on a dyno and specially one that has no cats in it, just straight pipe all the way so nothing to catch those fumes

you should see mine LOL

You're right, I've not seen one.

I was just surprised that it happens like that - I mean, through a lot of RPM range, then all of a sudden two puffs of smoke...as if it's building up in the exhaust then gets blasted out....but I know that shouldn't be true.

I got my money on the kart!

have you posted a dyno chart? I am currious as to torque, specifically low rpm torque. Looking to compare it to a s/c.
thanks

I will post up the dyno later when I get to scan it.

The curve is pretty flat all the way across with max at 333RWTQ on our dyno or around 370RWTQ on a dynojet

...The car did really well on the dyno...I am very impressed how well this setup performs and drives...drives like stock until the turbos come on...and they do come on quick!....the sound with the open wastegates is phenomenal in boost and quiet through the 3in custom X-pipe implemented during normal driving...all I can say is WOW...this car feels like it should now!...more vids and pics on the way...stay tuned!...

Any chance we could see the release of a kit which doesn't maintain stock drivability and the turbos don't come on quick?
