maybe the PT4400 would be best for my SI car, it only weighs 3200ish and im down on power so i dont think it would be to loose...but i only have 3.23 gears, and i dont know if its staying stock internal but it would be nice to run some low 11s w/o a cam

I know that you don't have to oblige me but you still didn't answer my question about the shift point and extensions, yet you took the time to answer everything else. What are you hiding?
And Red Alto bands have nothing to do with your 3-4 clutches. It sounds like you are saying that you have a stock trans with a red alto band.
No, I'm still in the 11.6s but it's also a 3550lbs car with my A/C all my seats and the stock 17s on it. And it always will be. Good luck on your quest for MPH

You answered all of my questions that only required opinion answers but left three out that could only be answered by actual facts. The RPMs, what data logging software and the 3-4 clutches. Like I said, you act like your hiding something.
The only reason I ask is because I've have seen similar recently with an SS4000. It had a great 60', a good 1/8, not so good 1/4 but horrible MPH. All that was changed was the converter. It lost 4 mph in the 1/4 over the stock converter, where it SHOULD have at least gained 1 mph. Did about 5 runs, all nearly identical. Working on getting a fresh trans now, before I start just completely slamming the SS4000. Sometimes there are other factors at play, but I guess your results are just too detailed for something like that, huh?
And I know what you're after. Guess you didn't get my joke.

I was logging all the trans parameters and making sure the tune (AFR and timing) was spot on during every pass, and nothing was out of place there. And the only thing that changed was the converter. This was a 90k mile completely stock trans with only computer tuning to improve shifts (that was also done before the stall). The fluid is still looks and smells fine perfect and it still drives fine other wise. And it ran within .1 all night, the only real difference in the runs was trying different launch rpms. I've talked to Yank and others about this and the general consensus is the 3-4 clutches.
You can get aftermarket 3-4 clutches but not any others (that I've seen) which tells me that for some reason the 3-4 pack needs more than others.

It's not normal (never happens) that people lose MPH with Yank converters. With the stock converter this car ran low 1.9 60's, 8.0-8.1 in the 1/8 and 12.4s@ 114 in the 1/4. After the converter it cut a 1.56 60' (Pulled the driver side stock 16), 7.5-1/8 and 12.0-@110 1/4. I can't remember the 1/8 mph right off hand but it was the same before and after. The DA was slightly worse but not enough for that kind of drop in the 1/4, especially since the 1/8 was much better.

I have tested both on my car pt4200(not a typo) and a ss4000...with 900ft better air I ran .5mph slower with the pt4200...the 60ft was .01 better with the pt4200 on the plus side...
the pt4200 just loses too much hp up top...I should have been up at least 1mph with the better air...so the pt4200 loss me around 1.5mph...
I wanted the pt to be better but it wasn't...my vote is the ss4000 but it looks like I am in the minority, either way if you get a pt or SS they are both very good...if you do pick the pt I would make it a pt4000...

Just to go ahead and put this out there. I just read the thread that Chris posted the link to (his head/cam dyno thread). The car is shifting higher than it should (possible indication of some slipping, but could be anything) and he also seems to have a rebuilt stock trans with a few hard part upgrades as well as a Red Alto band (no mention of upgraded 3-4 clutches, not that they wouldn't wear out either) and the trans was checked at the end of the 2008 season.
He also mentions getting an FLT transmission at some point. I'm willing to bet that when the SS4000 goes back in, that so will a better trans. And if he does that you'll never hear the end of my **** talking. ******* NEVER!!! Unless of course it runs slower still, then I would only talk minor ****. Just saying.
Keep up the good work Chris.
And I've seen heads/cam cars with similar setups to me that I've outran. That must mean that aftermarket heads and cams aren't as good as the factory stuff. You have an SS4000, so of course you agree with someone else who has an SS4000. That's why you can't believe half of the **** you read on this forum.
You're right. It doesn't mean anything without a little more detail.
