I hear all these stories about manual tranys and there clutches having problems and needing replcement ect. How would an auto tranny fair with a stage 1-2 HRC kit?


-Brian

It holds just fine. There are quite a few people running stage IIs on the AT and they are just fine. Joe (shogun98rs) is running his stock AT with like 18 or so psi. No problems what so ever.

Yah, I'm AT and it works good. Actually, much less trouble spinning the tires than a manual. Altho, Satan currently has my car in their shop trying to fix tranny problems that existed before the turbo. (Hard shifts at low loads, gridlock traffic). The problems got worse slowly after the turbo, but I think it's just a coincidence.

I got auto too.No mechanical problems.Still wish I had stick though.

im also auto. my goal is 14s w/ stock internals and the auto, but i wish i had a stick, seeing as how my car would be a feakin second faster than it is :/

I am automatic, and will be buying an HRC Stage1 in a few months. I have quite a few questions, so bear with me.

1) With auto, what would the best way to launch be and would it be more controlled than manual since Im not throwing so much power to the wheels? (Please dont mention torque or stall speed converter that isnt gonna happen)

2) On a manual, boost is built up. Then the driver releases accelerator and shifts, then pushes accelerator again. The throttle plate closes. On an auto, since the accelerator is never lifted, would my throttle plate close? If not this would mean I'd be able to hold boost right? Would a BOV function in this scenario since no air would be sent back?

3) Is there anything else I'd need that a manual would not? Transmission cooler?

4) With auto stage1, what kind of times should I expect on an HRC Super16G?

5) Your opinion, is this worth it? I can't sell my car and I looove the feeling of boost and speed. Its the ultimate rush.

Please don't flame me if you think the questions are dumb.

Same way you should be launching now. Power braking (or whatever you call it). Hold the brake down and push on down on the gas till about 2200 ... green light all gas no brake. Being auto this also allows you to build boost on the line ... can't do it in a MT.

You're right. The throttle plate will not close between shifts unless you let go of the accelerator. Therefore the BOV will not sound off. This is also good because you can maintain boost between gears and not have all the pressure vent out during shifts.

>3) Is there anything else I'd need that a manual would not?
>Transmission cooler?

A tranny oil cooler might be a nice addition but it depends on how you plan on driving it. If you're gonna be making run after run without letting the car cool a bit in between then yes if you're pretty tame with it then probably no. It's a good safety precaution either way.

Don't know. I'd guess high 15's.

I'm assuming you've driven a car with boost. It'll be a night and day difference with what you have now. It'll be worth it and it opens many paths for improved performance that you didn't have before. Just tuning your stage 1 can yeild better times but tuning your NA really doesn't get you as much. It's definitely worth every penny.

Like avenger said, just power brake as high as you can hold it. this is where higher stall speed convertor helps, cause you can bring the rev's up even higher. with the stock tranny you can bring the revs up to 2000-2500.

the bov wont go off during a run, cause your always in boost. that means not having to build boost again in the next gear, once you hit full boost in 1st, youll have full boost till u let off. the bov only goes off when you let off

DEFINITELY get a tranny cooler with the a604. heat is the #1 killer of the a604. seems like 2-3+ trannies go a month just on the ASOG board. Im on my third (had it rebuilt right the last time tho)


>4) With auto stage1, what kind of times should I expect on

high 15's-low 16's, depending on how well you can get off the line. but from a roll, youll run with cars that run quicker times.

definietely worth it, but youll be upgrading soon

Hey Ryan95i4,

What'd you do to your tranny the last time you had it rebuilt? You know what makes it "right". Mine's on it's last leg but I'm pretty sure once the turbo goes on it'll just blow itself up. I'm curious what you did in case I need to rebuild mine (in case I don't attempt the AT/MT swap) after it breaks. Let us know. Thanks.

So how much did that cost you? but more importantly how much of a difference did you notice? Send me some email about it avenger@quietrage.com ... Thanks.
