need serous stopping power

[SeanMc]

Are you smooth with your braking or are you trying to jam them on hard to slow down quickly? You're at a disadvantage with the ATX (not only because of the weight) but because you can't engine brake or match your revs while downshifting very efficiently.

While I don't advocate downshifting and rev'ing to 6K to slow down the car, it is helpful to downshift as you are slowing down; its less work on the brakes and it keeps you back in the powerband for exiting a turn. Yes, it's possible to downshift an ATX but it doesn't work as well as it does with an MTX.

Having the 11.6 in the rear has helped this. Freaking thing stops on a time. Oh, and having a higher stall torque converter negates everything you just said about the ATX not being as good as the MTX coming out of a turn.

It's hard to beat a Quaifed MTX coming out of a turn...

You got that right.
But still, I think I want to give the turbo atx a shot, sounds like a hoot!

 

[Todd TCE]

Good discussions.
Yes I used the .81 rotor for many years. Not for its all out performance but rather its ability to fit behind the slicer (with TCE hat) and allow the wider caliper to be fit to the rotor. I'd certainly suggest a min. 1.10" rotor for most track day users knowing what I do today. But...you'll need new wheels to make it happen. It's always about the compromise.

actually I played around with the shift points in the tweecer to keep the engine in the upper 4K so it will only shift at 6500rpm and will downshift around 3500-4K. obviously a track only setup. I don't know how smooth the downshifts will be so i will have to play with it and see how it works.

I haven't had the opportunity to drive one. But then again, have you driven a high stall ATX? Seriously, the difference is night and day.

When you power out of a corner with a Quaife the front of the car tucks into the turn. When you don't have a Quaife and you power out of a corner hard, the car will go wide, the inside tire go up in smoke or both.

The only time I've had the inside tire go up in smoke, is when there is water. When there isn't, it powers out nicely.

Then you're either not cornering very hard or you're not getting on it very hard.


...or you don't have a front swaybar...

I vote for the latter.

I agree. I have smoked the front tires powering out of turns in 1st, 2nd and 3rd gears.

I once owned an ATX. Hands down, you can get on the throttle much harder in a turn with a Quaifed MTX than with an ATX.

Ian

23mm front swaybar. I've taken turns at 50-60mph, and then gassed it, and I had no wheelspin unless it shifted gears (small chirp). I'm not saying either is better, but I've never had the wheelspin issue.

 

[drivinhard]

The stall speed of the TC has nothing to do with the differential action. The ATB Quaife is light years ahead of the open diff, MTX or ATX.

 

[somedude_001]

I have had the honor of driving a quaifed car and it really is a completely diferent expierence.

I'm not saying either is better, but I've never had the wheelspin issue.

I took a fast corner at about 85 and decided to floor it twords the end of the turn and when it hit boost the car went straight twords a wall thank god i didn't hit it. my point is you just need more power then you will have problems

QUAIFE PLEASE MAKEA DIFF FOR THE ATX!!!

Out of curiosity, do you not want an MTX? I'd think it would be easier to drive, handle and would've been easier to turbocharge.

[HotRodKid]

it wasnt that hard to turbocharge ....

and alex hasnt hard to worry about blowing up 3rd gear either ....

You're just not close to the grip limit of your tires, which is fine (and recommended) on the street. Try an autocross course, slow, tight corner, and try to get it out of it in a hurry close to the grip limit.

Let me drive it...

Doesn't Doug Lewis do a differential for the ATX?
