WhoaHoo! Just got back from Capitol Raceway

Postby edv-tek » Sat Mar 31, 2007 6:47 pm

Just back from the track at Capitol Raceway. We had rented a private session there. Nice weather 73 degrees low humidity. The car did real well with runs. I started out with a 13.86 sec and ended up with a 13.55. I was between 97.62 and 102.52 mph. My 0-60 ft times where between 2.048 and 1.808 sec. At first I was shifting into fourth at the end of the track and then stayed in third and got my best times. Even though the tach was between 7.5 and 8.0.
I was pumping the gas to get the turbo spooled on the line and leaving at 5-6000K. The beginning runs I was at 12.5 lbs of boost and for my last run at 13.55 sec was at 17 lbs of boost The only alarming time was when shifting from first to second the gear shift knob came off in my hands and I looked at the boost gauge and I was at 26 lbs so I shut the engine to idle and got off of the track. So I turned it down to 17lbs. and did my last run. I did 7 runs. I had a 1/4 tank of gas and I added 2 gallons of 110 leaded race gas. They didn't have any 104 unleaded.
In the end all the damage I could tell was the shifter knob coming off. All I have to say is that if you take a car to the track you better have a heavy duty clutch and be prepared to run your car harder than you ever have. Make sure every thing is sound on your car or it could be devastating...
In the end I was pulled over on the way home and was given a state inspection for my aussie exhaust. So I make an appeal to the local all-trac militia to sell or let me barrow an stock exhaust center pipe back to get tested with and change it back to an Aussie again. Damn search and destroy units always picking the low hanging fruit. I won't give up!

Getting an aftermarket manifold with a larger plenum and no tvis will do wonders for your top end.

Ed,
I was just thinking, how long do you have to get your inspection? Because we can get historic tags next year which will make us exempt from all the inspections. Something to think about :wink:

eric- The car can do more than that. It is conservatively tuned(rich) but it needs cams, Hydra-nemesis w/wb. The way the car is set up it dynoed at 250WHP. With some tuning it could easily go up to 300WHP. Although I don't plan to race it much more I will if I get some cams and stand alone eng. management with wide band.

Avi - that would be a god send. In the mean time if I cannot find an exhaust i was wondering if I put a aussie centerpipe w/catalytic converter would it quiet it down enough. With a catalytic convertor I would be in compliance. And if just the noise would be a factor I could put any muffler on for the tailpipe and quiet it down and then just swap just the tailpipe out.

Willie - If i can get respect from you and your half trac, I feel gratified. You and Eric seem to be running neck and neck so I don't want be a distraction. Carry on!

Mr WOT - Do you mean intake with a large plenium, like a Ross or ChrisK? With the TVIS absent can you program the stand alone to suppliment the lower end? I have seen the replacement plates. Don't know much more than that can you clue me in. Thanks. -ed

Anyone out there have any experience with the aussie centerpipe with the catalytic converter? Is it quieter or more restrictive?

a converter should quiet it down plenty. do you have a silencer for the muffler?

yes the muffler from Aussie? Am I missing something? There is a plate that is bolted inside the tip? A baffle?
I believe the way the cop explained it to me they were targeting or prejudging the car according to how large the tip is. And he assumed that it didn't have a muffler. But the exhaust is window rattling loud. My family told me as well as friends.
Through Aussie the midpipe w/cat cost $555.00 and the cat back w/ the twin tips cost $870. Thats $1425 for both parts + tariffs. Not to mention to pass a decible test at the emissions testing facility. But it would have more of a stock appearance and would have the catalytic converter. Thats alot of money just to comply. Maybe I can get some of my money back by selling the used aussie midpipe and cat back. Don't know how long it will take between the time I order and when it is recieved. I will check other options as well.

You should definitely be able to run much faster than that at 17psi. I ran a 13.3 @ 102 mph in my 1992 All-Trac using a TD06. I was on the stock fuel system and stock ecu running 13psi boost.
Best GT-S STOCK times: 1/4: 14.788 @ 94.98mph 1/8: 9.640 @ 75.87mph
Best Alltrac times: 1/4: 12.2 @ 115mph 1/8th: 7.9 @ 91mph

Agreed. I already said this. I was thinking more of a 13.0 flat.

Yeah I could run that. If you upgrade the turbo it would make sense to get more out of your engine and upgrade the fuel system. I can look at the 2 and 3rd cylinders and start to worry about the ping demons setting in and starting to a hammering even at your boost level. It's not about boost it is about running lean at the wrong time. I wouldn't advertize that.
