HUGE PROMBLEMS ARE AFOOT! I have an automatic 2001 TransAm. Before I had anything put on my car I ran a best of 13.40 for my quarter mile with two extra people in the car, one in the back, and one working the g-tech in the front. From this I took it without the two extra people I could a low 13.3x, at least!

Being such an idiot, I never tried again (I actually did, but due to certain situations and conditions I was prevented from getting any good times).

Just this Monday I got my FTRA and Whisper Lid on (I already had a K&N Filter). I thought maybe with this I could get at least anywhere from 13.00-13.20 (being hopeful!).

So just tonight, Saturday, I went out to my race night and talked to my friend with the g-tech. We went out to a secluded place and began to test my car for new times. I roasted the tires a little for some better traction on take off and began to run the 1/4 mile. The way I race is I leave the traction control on power brake and rev to about 1.0-1.5rpms (if I don't have the traction control on I just spin the tires when I take off and begin to move sideways). I then take off, but during these times I noticed I wasn't getting off immediately like I had for my 13.40. It seemed like everytime I took off the "low tread" light would come on. My first few times were real dissapointing, mostly just 13.50. We thought maybe since the place was a little bumpy and with gravel it could have effected my start off greatly.

So we went back to the place where I had got my 13.40. I roasted the tires again and began. Same things kept happening??? We tried once just taking off without revving and got a new best of 13.34. We tried the other way again, even at 1.75rpm, but no help at all.

My friends and I talked about it and thought of a few things. One thing is the K&N filter is filthy, and I should use the other I have that is very clean. The next thing I thought was maybe it was the G-tech, but they said it wasn't. My friend said that last time I had about a half on tank of gas, and this time I did it with a full tank gas and that might've had something to do with it. We checked the the tread (on my stock tires) and they are barely gone, so that wasn't it. I then thought maybe it was the computer doing something since the FTRA was on, but I don't think so. The rubber part of the FTRA wasn't on either, so we thought that might've had something to do with it. The only other logical thing we could think of was that when we had my third friend he helped weigh down the back and help the tires stick to the ground better.

One odd thing I did notice is that when I had got my 13.40 my first time it was at 118mph. One of my 1/4 mile passes this time I had gotten 13.40, but only at 110mph???

I am planning on putting 12" subs in the back, which will help weight it down a little, if that is indeed the problem.

This really pisses me off, because having this induction stuff is supposed to help me be better than stock, not slightly better, or worse!

I would really like some feedback on this, I want to try the g-tech again tomorrow and get new, BETTER times... If anyone knows the names of other purchasable devices other than the g-tech that does 1/4 mile times, please tell me that as well. Thanks, and sorry for the long-*** post!

Hey, Gtech sucks!!!

get your yourself down to a real track.

oh yea 118mph with a stock motor not possible.

 

I would recommend not doing a burnout with stock tires. Seems to make them greasy to me. Just a quick little spin over to knock of the dirt is all you need, IMO. Also, traction control tends to overcompensate whenever the tires spin even the slightest bit. With practice, you should easily be able to launch better with the traction control turned off.

Oh, and get to a track! <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

I knew that damn g-tech would f*ck me over! Thanks for the advice, you don't think it's the weight in the back? What reasonable time should I expect from my induction stuff? Thanks.

 

Hey man I am having the exact same problem with my 99 trans am. I have an a4 with 3.23's with a lid and K&N. I will totally roast the tires through 1st when lauching from idle! I have dropped my psi down to 26 and have tried half throttle punhces but I still spin like crazy! Anybody got any helpful ideas as to how to ease into the gas of turn traction control on and maybe drop psi some more. I am on stock tires by the way.

 

With practice you should be able to feather the gas to minimize wheelspin, but you need some good tires, you will never get a clean launch on stock tires, IMO.
If you want times, get to a track, the Gtech sucks.
BTW, adding weight to the rear is just a band aid for traction problems. You should be trying to lose weight to go faster, not add it!

With 2 people, assuming they weigh roughly ~170 lbs a peice, you're losing about 3-4 tenths.

You have to be on a perfectly flat road for a g-tech to even be somewhat close.

There are completely stripped bolt on cars running 120 mph.

Rule #2- G-tech's are ricer tuning tools. Go to the track <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Went and did the g-tech (I know, GO TO THE TRACK!). Well first I had my friends pile in the car, just for fun, and to get the tire ready for some real runs. I got an astounding 13.4x!!! That was funny! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I then went out on my own (with TCS off). I played with the car a bit and was able to get a new best of 13.21 at 111.3mph!!! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> It was great, I now need to practice a little more to get 13.2x consistently (I got 13.23 right after as well).

Does anyone think I might be able to get 13.19? With TCS off, should I rev up first or just go from idle? Thanks a lot.
