TCI 3800 competition converter ???'s Is this a 3800 or not???
I've had this converter for some time now and have only recently taken it out for some quarter mile blasts. What I noticed is that the actual stall seems to be much lower than 3800. I clearly understand the difference between a foot stall and flash stall. It does not seem to flash very high and the foot stall goes to about 2200 before spinning the tires. Does this sound right??? My 60 foots on 26 tall et streets were 1.77. But, it just seems to not rev out of the hole at all. The car itself is has 5.3 stage II patriots, a tsp 231/231, and a Victor Edelbrock Jr conversion, long tubes, and dumps. My gut feeling is that the manifold has lost alot of low end and I need an even higher stall. But, I'm just any sure whether the stall is even correct on this converter. I don't want to get a 4000+ if this converter if a good 3800 or 3600 will do. Any thoughts and ideas would be greatly appreciated. One more thing, I am spraying the car with a 150 shot of nitrous. Thanks.

Carlos,
Your 60 foots do seem to be a little slow for a 3800 converter. Do you have the part number for the converter? Is the 1.77 sixty foot on motor or on spray? I'll be glad to work with you and get the converter fine-tuned for your application.

Thanks. I don't have the documentation on it anymore. I do remember the invoice saying it was a 3800 Competition Converter. I was actually surprised because I thought I would be getting the SS. It was ordered from TSP, but drop shipped directly from TCI. As for the sixty foot, that is on spray. For awhile there, I thought it might be because of a rich condition. But, we tuned on it yesterday and it doesn't seem to be the problem.

Are you sure you're not spinning (you may not feel it)? What tires are you running? That converter hits hard especially on spray. I was pulling 1.5's on a stock internal motor with the same converter so I would say something isn't right and I bet it's suspension/tire related.

Holy crap!!! Put this thread on hold. After reviewing the video, it seems like the shift is far ahead of the 60 foot. Take a look and the video and give me your thoughts. I just changed the shift points yesterday for the 1-2, so I'll try this again on Friday to see what the change is. There may not be a problem at all.

I can't really see the tires, but it does sound like the shift is way early. It "sounds" like the car is reving high and shifting early which seems to me like it's spinning even though you can't hear it. Spinning = Higher rpm faster to your set shiftpoint = shifting early.
I think the tires are the problem. They don't have enought sidewall or the grip for a hard hit from a 2.6 str, h&C, 150 shot. See if you can borrow a set of 15" slicks (preferably 28") and see if it makes any difference.

Actually, there was a problem with the shift points on the car which is why it was shifting way too early. The mph for the gear change was way too low. It was also doing that with the 2-3 shift on previous runs that evening and so we just shifted the 2-3 manually on that run. The car really needs to be shifting about 6600 and on that pass it was about 5900. I was next to the car, not shooting the video and the tires were hooking. Quite honestly, after reviewing the video, the shift into 2nd, especially at that rpm, is killing the 60 foot time. I agree that some the car will definately benefit with a 15 inch wheel/tire. I think the best 60 ft time possible might be a 1.60 with those 17's (if that at all), Man, I wish I had your 60 ft times!!!
