Well... I took the plunge as well after hearing all the great results with the now famous PTC 9.5 n/l converter.
Now, I am not a hardcore racer like some. Just a guy that wants the car to do what it can without having to kill it at the track. (which is what we all do anyways:wink
My car is very mild, and light compared to most TR combos. So, I wondered if my application would be a pass or fail. After the initial install I was (very) concearned this would be WAY to much converter for my mild car. On the first drive I continued to be more impressed by the way it worked and drove. My buddy, who is quite finicky about driveabilty, and overall "sceptical" of non lock up converters, was as impressed as I was. It is a bit loose on initial acceleration, but, after that the converter is all that I had heard about.
So, Sunday I head to the track. Very nice mild November day here in Michigan, it was about 65*. It was an awesome drive, and impressive as well. I removed a very popular lock up converter I wanted to test. My RPM at cruise was within 50 rpm of a lockup unit. 2200 @ 70mph, as opposed to the 2350-2400 I was used to seeing with my old n/l conv, and 2150 was the typical lock up rpm with the last converter I removed. Nice! At 60 mph, it was just awesome being under 2000 rpm. Nice and quiet in the car. (except for all the wind noise from my rotten seals)
So... I got to the track, and I would like to tell eveyone I ran 3-4 tenths quicker. But, I did not. No big deal. I had to figure the new combo out, and without a cage, they are not very accepting with my antics anymore. So, it was 1/8th mile time. It took me a couple passes to find where the car would launch and not spin. The track I went to is affectionatly know as "La-smear" Dragway, as it can be difficult to hook there unless it is a race program day, or you said alot of prayers the night before. I got a couple decent 60fts, and a couple spinners. I modified my launch for the day, and I am sure it killed a hint of ET. But,, it was a must as anything over 7 psi resulted in tire spin.
With my new found knowlege, I decided it was time to go for it. Got the car up on about 7 psi, and had some tire spin. But, stayed in it anyway as it was time to bail. Low and behold, my rpm through the traps was over 500 rpm lower than my old converter!:biggrin: Went through the traps at only 5075, I would always be over 5500 through the traps with my old combo.
Ultimatly, I ended up with my best 60 ft, 1/8th mile, 1/8th mph, 1/4 mile, and 1/4 mph. Not by a bunch, but... better none the less! But, now with out revving my stock cam to the moon to do it!
Thanks Dusty and PTC for a very nice part.!
