Team 607 WRX hits the track :)

607Motorsports · #1 (**permalink**) 09-21-2007, 11:27 AM

On a spur of the moment thing we decided to head to the track this past Wednesday to get a few runs in with the Scooby in hopes up getting into the 12's. The car has been having issues building boost off the line (it's an auto) and the best runs to date were mid 13's. After some tweaking and troubleshooting it looks like the car will not build boost unless it's hot. When cold the car struggles to build 3-5psi... when hot we were seeing about 12psi before the car began to creep. Below is the best run of the night and a video, enjoy!

My apologies for the video being a bit blurry... my camera was actually pretty much dead that night and when that low on power it has major issues focussing in the dark.

Best Run:
60' 2.188
330 5.608
1/8 8.442
MPH 86.43
1000 10.885
1/4 12.930
MPH 107.78

Congrats on the time, but that seems very inconsistant for an auto. I was more consistant than that with my M6 Z28. Were there other issues or something?

The runs that were slower were due to the car not building boost off the line. It wasn't until later in the night where we figured out the car needed to be warm to build boost. The 12.93 was done launching at about 12psi compared to the earlier runs of 3-5psi.

What turbo is the car running?

Why did you only gain 5-8MPH after introducing 12PSI?

The car is running a VF-34 turbo at right around 20psi. This is not my car... it's my buddy Dan's who is a member of 607.

Shawn - I'm not sure what's going on with the car right now... The car traps 106-107 consistently no matter what it runs for time. We were able to squeek out a 109mph on one run which was a 13.6. For some reason the car only seems to build boost off the line when its hot... We could have went higher than 12psi if the brakes would hold it... the car starting to creep. However when the car is cold it has trouble building even 5psi. We are still looking into the issue because it just doesn't make sense to us... I'm not really a huge auto guy so maybe i'm not thinking of something

Wait. The car is making 20PSI? and trapping that? I thought 12PSi but that's off the line. Right?

Any boost leaks? Any timing pull? I'd expect much higher.

its an auto....on a 2.0 block... 12.9 is a very respectable time id think.

mikecentola · #10 (**permalink**) 09-24-2007, 09:50 AM

yeah very decent time... i had run a 13.1 on a vf-22 (bigger turbo) @ 19psi

Who gives a shit about the ET?

The ET comes with power. If the car isn't making the power (trap), that's where the potential problem is. I have no idea what that car should really trap but I thought it should be more? Perhaps that's about right as I initially confused it with a 350Z (bigger displacement).

shawn... the car is trapping 3-5mph faster than a stock sti which this car... albeit modded, is most likely not even making as much power as the sti... OUT OF AN AUTO! 108mph traps on average are respectable out of that car no doubt.
