Good luck and I can't wait to hear the ET's

Someday I have to do something for a stronger tranny, but haven't decided what it will be yet - I want to keep it on the street at least a little and be able to cruise some. Well, my A4 is holding up well on motor, I just have to stay away from the bottle!
If you asked me could I drive on the street, I'd say sure, if it wasn't so loud. There's nothing in it that would get hurt, but with a loose converter it's a slug at part throttle. As far as weight, my tranny builder has had success at a 3400 lbs weight, but I'm guessing that was with some big power.

My lengthy history with past projects of trying to have a street and strip car has always left me somewhere in between and not great at either This time around she's a trailer queen and I'm happy to say it.

You can say that again I don't have the time to put the full exhaust and street tires back on every week or even once a month for that matter. I can't go 136 mph on the street legally and don't want to try to do it illegally. It's stupid in my opinion.

My car is drag only and proud of it.

BTW a 2 speed would be OK for the street. It was made for street use. That was the original idea.

Power level? 540 SAE at the wheels and lots of torque.

I have a COEN converter. Its an 8". The stall speed was built to engine specs. Never did know the stall but it's probably about 4600. The converter flashes to around 5500 to 5600 when I stab it. Sorry I can't help much there but I really don't know the stall speed.

Race weight was around 3300 to 3350.

Gearing is 4.86 for now. When the weather cools down I'll go with a 4.70 and try that.

Weather will be pretty cool for the summer months this weekend
I take it you're using a 4.125" crankshaft?

when i was thinking about what my final combo would be after my swap the glide was really the only thing i looked at. they are easy to make strong, don't rob a lot of power, and save 75lbs+/- over a th400 or 700r4/4l60e. if you are tryin to go quick on a "streetable" combo it only makes sense to not waste power and reduce weight.

Very true

For the street racer a power glide will hook up better than any transmission.

That sounds like a cool Hot Rod!! The yellow Camaro we built has a 10.5 31w tire with a 5500rpm stall and a 1.99 first with a 4.88 rear. With the 402 C5R head engine it would run 1.28-1.30 sixtys at 3250 pounds.
When it had the turbo 350 trans it ran the same sixtys at best but was inconsistent.
I tried a 1.85 first and it slowed the sixty down into the mid 1.3X

It's nice to hear from some of the hardcore guys that back the glide. At 37, I consider myself more old school and never understood the one's saying a glide won't work in an LS1. All hail the glide.

I don't know where all this anti powerglide info cam from anyways??? Its like every magizine has printed "don't use a glide over 3000 pounds", and now people belive it like the bible.

We swapped a glide into our 2002SS, @ 3420 pounds...and it ran GREAT. Ran consistant high 1.3's on the spray...thing was, it did that no matter what the track serface was like. Track prep became not so critical. Also.....as far as streetablity. I love it! With the right convertor, its no worse than any other automatic tranny. And the reduced gear on the street, it hooks like crazy on just good concrete (for you midnight 1/4 mile racers

Im confused. Everyone says the stock A4s are so great because of the 3.06 first gear which is much larger than the glides first gear. The drop between 1-2 on the a4s are similar to the glides. Maybe people should gear a4's so they only use 1-2 in the quarter mile.

Seriously though, with the right converter gear ratios dont matter much?

"Maybe people should gear a4's so they only use 1-2 in the quarter mile."

That would work just fine if you had enough power to make it work....unfortunately, the 4L60-E won't take that much power!

The more converter you have, the less being undergeared matters.

I don't race on the street - but I have to (and want to) keep my car streetable to some degree. I don't have a full size truck and don't have the money or place for a trailer (townhouse). I drive mine to and from the track and to cruise nights only - it is not a daily driver. I uncap my cutout, lower the pressure in the ET Streets, and go racing.

I'm not anywhere near the level of power you guys are (I'm at 415 rwhp now and 3575 raceweight), but wondered if a glide would be a dependable option for me one day - then I could spray it without worring about the 4L60E going six feet under.

So what would I have to do to consider it? Lower the raceweight a few hundred pounds? What stall and gear would you run with a glide in a car like mine? What rpms would I have to shift and trap at? I currently shift at 6,400ish and trap at about 6,100 in 3rd.

Just wondering if it is even possible in a car like mine. Thanks for the input.

realistically you can run a glide with the weight of your car as it is now. glides are very strong little suckers and can take the abuse of big power and big weight if built properly.

I wouldn't be at all scared to run a Glide in a ~3400 lb car with ~550 RWHP. I'd pick my 1st gear and rearend gearing wisely though.

Colonel,
How would you pick them? Can you explain some more. Thanks!
