A pic of my best slip:


The 3rd of 6 runs was the best.

Yes my reaction time sucks.

RT:           .6347
60ft:         2.2082
330 ft:      6.1772
ET@594ft: 8.9055
1/8 ET:      9.5141
1/8 MPH:    73.93
1/4 ET:       14.8083
1/4 MPH:     91.45

I had traction issues off the line all afternoon. My worst run was a 15.1773 @ 90.70 MPH so they were all pretty consistant.

What do ya think?

      actually I like that reaction time but you must be a constant racer and your ET time also looks good to me

Thanks, It was my first time ever to the track I LOVE IT!

I just wish I could get it to hook up off of the line.

that's pretty good Matt, not bad. what other mods do you have besides the hot tune? and what elevation are you at? back when Greg had the TSTE it pulled a 14.86 with a UDP and some kind of chip that I'm not even sure on the origins of, lol, so hopefully with current mods I can sneak by by your extra .06 :laugh:

Thanks Tony,

The car has 1.6/1 rockers, FFP UDP, FFP mounts, Magnecor wires, Jeff M X-over, Turbo XS BOV, boostvalve.com 2 stage MBC, K&N cone, and the Hot tune.

Thats pretty much all the mods motor wise.

I'll have to look up what the elevation is.

sweet, how many lbs are you running with the MBC?

You sure you had the Hot Tune chip in there and not something else? Your times seem slow for what is done to the car. How much boost were you seeing during that run? Going by the times that Jamie posted for his GTP on the other forum, the weather was decent enough to run some really good times...

A bit off what I figured considering my wife's TSTE ran a 14.202 at 96MPH at 5800' on the same tune.

One trick you will want to try which got my wife's car to that time...do not run WOT to allow the tranny to shift at lower RPMs. If you can get the TC to lock/unlock and give you a constant 4200 - 4400RPM down the quarter you will run considereably faster. If you are shifting at WOT and the RPMs are holding at 5000+ you will be slow because with the T25 backpressure issues you will be out of the torque and HP beyond 4650-ishRPM. Worse off with a TopGun or Stock tune.

Honestly considering it was your first time to the track with the car (or ever?) you were in the 14's! Guys spend thousands of dollars on some production cars to get them to finally break into the 14's and with some minor practice you were there already there with a car that in stock form was barely called a 15 second car. Yes I know the magazine article showed a 15.3 in the quarter...but how many factory off the show room floor cars actually put that time down in true factory trim?? ;)

Fill me in on how you launch, where is the tranny shifting, are you matting your foot to the floor, etc. With a little advice over the wires we can probably get you into the 13's. At least a flat 14.  :icon_mrgreen:

How much quicker did you run getting the transaxle to shift lower vs. shifting where it does @ WOT Kenny? Was the "Hot Tune" listed on the dyno chart where you compared to Jeff's chip and stock or was that your Hot/performance chip? I'm curious because on that dyno chart peak power for your chip looked to be around 4900rpms. If that was the case, it seems like shifting just a bit past 5K  would be the best point to shift.

Sucks to have an auto :laugh:

Kenny, can't the torque converter lock/unlock settings be changed on the chip? Perhaps what we're talking about wouldn't be the best for everyday driving, I have no idea. But it that were the case, maybe a WOT/RPM activated switch could be used (in addition to the ECM) to lock the torque converter, so that letting off the throttle wouldn't be necessary.

I don't really fully understand how torque converters work, so if I'm talking out of my ass just ignore me  :icon_wink:

I wasn't running the MBC when I was racing, I was using ECM controlled boost.

Yes the hot tune was in it. 10-11 psi of boost on my autometer mechanical gauge. To me the car seemed real good in the 1st 1/8th but ran out of breath in the 2nd 1/8th. I also had a hard time getting off the line without a lot of tire spin.

It was my first time to the track ever. Quite honestly, the light turned green and I nailed it and held her down till the finish line. That was my "technique". So the trans was shifting at WOT around red line. Seemed to run out of breath up that high.


When you think about it, the car is pretty much stock, just tuned up, with a performance chip and a couple MINOR bolt ons.

I have to say this again and again but adding more power is great but if you cannot hook up NOW you certainly will not with more power.  Sure more power might get you a lower time but so will a set of DR's or ET streets!.  A 2.2 sixty foot leaves much room for improvement.  If you could cut a 2.0 with some sticky tires you could definitely get a 14.5 out of that car!  Invest in some tires and learn to use them before upgrading anymore, you will be glad you did.

Ken

Right now im running Goodyear Eagle F1 DS3's on the front that are on the wear bars so new sticky tires would definately help. I just dont wanna take out the trans either.

Yes the TC can be told where to lock unlock...but the actual shift point under WOT is determined with the trans RPM and the kick down cable. The nice part of my job with the new Electronic controlled trannys is I can dictate exactly what RPM, throttle position, and load point to make the car shift 1-2, 2-3, 3-4 and all of the TC lock and unlock points. I have one LS1 A4 car that sounds like an Allison 6 speed shifting down the track. Talk about holding in the power curve! :icon_eek:

The problem with our cars is they are torque motors...not HP motors. If you are shifting all the way up past where the HP lays down then you never get back into the torque curve. Torque turns the wheels and HP will carry. If we can stay right at the torque curve peak rather than the HP peak you will run MUCH faster in the quarter. Example...7200lbs Cummins pick-up truck with a few bolt on power adders. The truck is only laying down 450HP, but it still makes a 12 second run....WHY? Answer...It has nearly 1000 ft/lbs of torque turning the wheels. Now put that same motor in a vehicle that is 1/2 as heavy...you have an 8 second car. Not possible with just a 450HP motor...again the 1000 ft/lbs of torque turns the wheels. Make sense?

What I did with my wife's car to make a 14.6 run. Iced down the engine/intake before the run with minimal running to get to the line. Slight power brake just to get the turbo to be "spooled" and ready to go showing maybe 2psi_g of boost. Rolled into the throttle to get off the line without spinning the fronts like they were on ice. Matted the throttle full at about the 60' mark or slightly passed and held it to the finish line.

What I did for the 14.2 run...Iced intake. NO POWER BRAKING other than to put a slight load on the tranny, motor mounts, etc to avoid that violent motor twist when the car took off on the VHT prepared track. ROLLED (quick and smooth) into the throttle when I left the line until I could feel the tension in the tranny kick-down cable (about 3/4 throttle...maybe slightly more) and floated it there all the way down the track. My tranny is very clean and you can feel all of the locks and unlocks as it moves up through the gears. My tach never went above 4400 - 4500 RPM all the way down the track. When it shifted it would drop to about 3800-ishRPM and pull like no tomorrow.

Remember that even with the throttle at 3/4 you will flow the same amount of air into the cylinders as when you are 100% throttle as long as you are producing boost. You will have the same amount of fuel, spark timing, etc. The PCM is looking at RPM and the MAP sensor...not TPS for the absolute load point.

Try that next time using the torque to pull the car rather than thinking redline is where the speed is! ;)

Those a pretty good tires for the track, my friend had them on his 92 gpse with hopped up 3400 and I ran a 14.9 n/a with a 2.0 sixty.  What will take out the trans is pegleg burnouts.  The diff spider gears will explode because they have no bearings in them, it is just a polished pin on the bore of the spider.  When you pegleg the spiders rotate, get hot and start to smear material on the pin.  After a while they will sieze and diff. explodes. 

If you use some sticky tires do a burnout starting IN the water box, then slowly roll out of the box until they catch.  Don't do another burnout or it will pegleg with the auto.  The go up to the line and powerbrake it....or nail it whatever you want.  With et streets it will hook.  With that method I tree'd a ls1 camaro on thos ds3's even though I feathered the throttle.  Good luck and have fun!
