It certainly will not improve things. The choice is up to the individual to asses and decide.

The QC offically went on sale today at svxworldforums. You can buy it here:

My car could not get in at the shop today to go on the dyno, we're aiming for tomorrow morning. I will post the "after" results/videos as soon as I get them, hopefully tomorrow.

For those wondering...it takes a bit of navigating and forum scrolling to find it...the kit is $140 shipped. Production rate is 10/week and they're shipped from Australia so you may have to wait.

Of course if less than 10/week sell I guess availability won't be a problem....DOH!

The kit is being installed saturday and the AFTER dyno results will be posted sunday or monday.

THIS IS THE AFTER DYNO RESULTS!

My car did considerably better on the dyno today. It actually shifted into 3ed this time. The guy that runs the dyno said he definately noticed it shifted a whole lot better.

Why does the power spike at gear changes? What causes this, and more importantly, what's that doing to the driveline? That much power coming on and off in a very short time can't be doing anything good.

Wannarace,

Could you ask the dyno shop to plot the runs from both sessions on the same sheet of paper? The different max x-axis values (65 vs 100?) make is difficult to make a 1-to-1 comparison. Is there a reason why the shop isn't using rpm as the x-axis value? I'll have to go back and check, but I believe all of the dyno plots I've pulled together from folks on the network have been HP vs RPM and TQ vs RPM. This allows you to see what HP and TQ do as you run the engine up to its redline.
Thanks.

p.s. what is going on with the HP/TQ spikes?? Something just doesn't feel right with the latest plot, as the AFR stays at Stoich all the way across the run (?) Add to this the fact that the HP and TQ curves look identical (??)

Actually, the power coming on/off quickly is better. Less time slipping the clutches equals less heat. I don't think worrying about stock hp damaging the drivetrain is a worthwhile endeavor.

I like that way that car shifted, may have to add this to my wishlist.

Bill -

I can definately ask them to plot both runs on the same papper. I'll post it up if they can do it.

And i'm not sure why they are not using rpm, I can ask that as well.




Myteball -

I absolutely love the way the car shifts now. It is really awesome. It feels very smooth and much quicker.

I am anticipating the long term report after 1000 miles. The big spike kinda worries me but looks promising so far

I'm working on almost 500 miles already since it was installed. No problems so far.

Any increased tranny temps?

I am not sure on that, Budfreak might know.

I don't have a gauge installed on my car.

I have a cooler installed on my car though.

Shocks like that to the drivetrain will cause severe damage... Its not that the stock drivetrain won't hold 220whp its that a 70hp spike like that will shatter your axles, differentials, planetaries... you name it, its gonna break

I drive my car daily and take it on a lot of long trips. I'll keep everyone posted on how things are going, but like I said, it has already been 500 miles and all is well.

Lets hope for the best.
