PY3600E Flash Stall? I logged some rpm and mph launching off idle. This converter doesn't seem to flash stall very high. Running N/A on ET Streets with no wheel spin.

The 2nd run was not quite off idle, but still, 20 mph by the time I hit 3600 rpm? Does this seem right? This thing doesn't feel like a 3600 converter. 1.801 60 is the best I've cut with this on a heads/cam/LT header car. Can Yank do anything to this converter to make it feel like my old ST3800. I have no lock up issues with this converter, but I miss the performance of the ST.

Re: PY3600E Flash Stall? Based upon your data, its stalling to about 3300 - 3400 in your set-up. It's a pretty tight converter for NA use in a stock cube motor. He could up the stall a bit, but it will cost you some efficency. Yank has a new PYE 3800, but it will probably stall to 3500 behind a stock motor and it's STR is a bit lower.
Best solution is spray it and go low 11s <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: PY3600E Flash Stall? Here's the best way to check the stall. Put it in 2nd gear (car stopped), then hold the brakes and apply as much throttle as the car will take before it moves. This will show you full stall.
Best way to launch the car at the track is to load up the converter to as much rpm as it will take before the car starts to move. Your 60' times should be in the low 1.7s or high 1.6s if you do that.

I did make a few runs brake stalling it up a little higher and the car did pick up a bit. I'm just used to launching off idle with the STs because I always ran my best that way. Or just find another ST that someone has run with no lock up problems. Amyone want to trade??? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I don't think the 2nd gear test will work on my 99. I think that started in 00.

Re: PY3600E Flash Stall? Patrick:
A second 2nd gear launch (logging the data that he has) is the best way to test and is more accurate than brake stall.
2x:
Your data is pretty clear that you stall less than 3600. With a power adder you'd stall right around 3600 which is where the converter is designed to be.
I agree with that Patrick that 1.7s should be doable, but a full weight car isn't going to cut 1.60s on that converter. Air up the tires if you can.

Re: PY3600E Flash Stall? I used to cut 1.71 with my SY3500 and it's measly 1.61 STR. Now I did have 3.73 gears and my car was just a little lighter than stock but still I would think such a high STR "3600" converter should cut at least high 1.7s. What's he using, 2.73 gears?
I'm trying to decide what converter I want for my new 3.23 geared Z28 I'm getting today. It will be internally stock for a short while and then will have LS6 heads. Really I want a ST3800 but I don't want ANY chance of chatter issues so that leaves me with a 258 mm converter, right? Maybe this new PYE3800 would be the ticket. I want to be able to cut AT LEAST 1.6s. With a 3500 lb raceweight and 3.23 gears. I also want the car to be nice and streetable. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Re: PY3600E Flash Stall? Best 60 I cut with the ST3800 was a 1.71. I run 45 psi in the fronts when at the track. 20 psi in the ET Streets. I don't have any traction problems. The car is a pig weight wise though. It was 3720 lbs with me in it. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> I know there are some good chatter free ST converters out there. I have one in my 00 and installed another one in a friend's 00 Z that is trouble free. I have some 3.73's I'll be installing soon. I'm sure the car needs some tuning too.

Re: PY3600E Flash Stall? Ragtop, could you tell me how a PYE3800 would feel and perform with 3.23 gears compared to a SY3500/3.73 combo in a 3500 lb NA heads/cam setup?
I'm looking for great drag radial 60s NA and I want a streetable converter. The SY3500/3.73 combo was great (maybe still just a little soft off the launch with those 1.71-1.75 60s) but I'll be staying with 3.23s this time.
Might have to beg Mike to build me a ST3800 with paper clutches, huh? Think he'd do that?

Re: PY3600E Flash Stall? Colonel:
You can get chatter free in the 9" if Mike uses an OEM style paper clutch. A couple mph added to 4th lock-up generally eliminates the chatter too if it develops in the more agressive clutches.
I think the PYE 3800 is going to be very tight on just a H&C car and will not get you 1.6s at 3500lbs. I don't think it has been run a NA car yet, so maybe you can be the guniea pig. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
Until he brings the ST 3500 back, there is a hole in his product line for tight feeling, 1.6 60'cutting, converter. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Re: PY3600E Flash Stall? Colonel: It looks like the PYE 3800 would be about like a ST 3300 NA, but I haven't had a chance to standardize the converter dyno data from GM yet. Why they did this one differently, I haven't found out yet. <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />
CamaroSS_2002:
Boost would be perfect. Anything that gets the torque up.
390 ft-lbs at 3600 rpm would be nice. If that was through a locked converter or M6 dyno, that is a good result.

Re: PY3600E Flash Stall? So it would feel and perform about like a ST3300 NA? Well that sounds about like what I want (a very streetable converter) except for the no 1.6s at 3500 lbs part.
Maybe I can be the guinnea pig and prove that prediction wrong?
You know, I have what I *think* is a TT3200 that Mike built for my Suburban but I never put in. I'm going to try it out in this car just for the heck of it. Whatcha think? Low 1.8s at stock weight for a bolt-on, full weight car?

Re: PY3600E Flash Stall? Colonel - I ran a 1.80 '60 with a regular Y3200(1.8str) in my old '00 SS at full weight. The TT series is supposed to hit harder right. Maybe you could sneak a high 1.7 out of it?
BTW, that was in very good weather with minor bolt-ons. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
