D5 stamping on stock converter

[turbojoe]

Has anyone recently pulled inspection cover off converter? If so, could someone please describe what is stamped on their stock converter. Is it a large "D" and large #5 or is it a small "D" and a larger #5? Mine has a smaller D and a larger #5. From what ive seen in pictures (GNTTYPE) it appears that it is supposed to be both a Large D and Large #5. Poor spool-up points me to look at converter. THanks, JOE

Mine is a large D and large 5.

Hey MAXV02, What year is your car, 86 or 87? Maybe there was different stamping used for different years?

Mine is just a 5 all the way around...

Thats what I thought I saw on mine (5 all around), But when I looked closer, I saw a very small D next to the larger five. I wish I could find some clear cut literature on what this thing is supposed to be stamped from year to year. Like I said the off the line performance STINKS! No shreading the tires with this thing! Something is definately AMIS here! JOE

I have an 87.

My car is hardly stock, but it doesn't just go the way a non-turbo car jumps when you floor it. It takes a split second for the turbo to spool before the wheels break loose. That's why you hold the car with the brakes or transbrake to spool the turbo at the track for best launch.

I have other cars that are 2 seconds slower in the quarter mile than my GN that SEEM faster off the line, and more responsive, but it's just that they have no turbo, a real tight convertor, and low gears.

Thanks MaxV02! I am comparing this car (86 T-type) to my Former 87 We4. The We4, when i went Wot from a stop, would roll out a bit until it hit second gear and then It would just fry the tires for as long as 20-30 or more feet! This car won't even chirp the tires.

****Lots of what you post above depends on what kind of tires are on the car, whether it is cold weather, and/or if the roads in your area have been salted down recently due to snowfall, etc..

I saw a work van a couple of days ago just floor it around a corner from a stop and just spin it's tires for at least 100 feet.. I don't think the company the guy works for bought the twin turbo econoline option so it was probably the roads being salted recently, plus cold roads, plus an open rear out back going around the turn... Looked impressive but that's about it..

Bottom line is take the car to the track and compare times. Having rock hard BF Goodrich Radial t/a's on your car versus something stickier may allow you to spin off the line forever, but that will just get you a big fat ticket around here, and mebbe a few days in pound-you-in-the-ass prison if you are especially unlucky..

Hope this clears it up somewhat!

MAXVo2, I havn't driven car since october. Car is in storage for winter. I'm talkin on nice clean roads in summer time. I have Michelin Pilots on car. My We4 had the Bf Goodrich tires on it and did fry the tires from a standstill (no BraKe tourqing needed). Maybe it is the tires (Michelin more sticky than Bf goodrich)? I still say something is wrong with this picture though. I mean every single article/video says/or remarks on how these cars just burn rubber (except mine). Don't get me wrong, I'm not into beating the car, its just every once in a while it would be nice to show it off a bit. I'm not into racing it at all and never will be. But it would be nice if my car would live up to all the hype. Most people that own these cars try everthing to PREVENT the car from roasting the tires (people who race them And are concerned with the Best E.T.'s). I, on the other hand am trying to get the car to burn a little rubber.

**** I had regular BF Goodrich tires on my car when I first bought it, and ran them for a long time. My car was pretty much stock except for a chip and adj wastegate when I bought it, including having working Cat Convertor, etc.. And those Goodrich tires would just spin spin spin even from a 10-15mph roll.

I *thought* I had a really fast car until I drove in one of the faster GN's in my local area who had super sticky tires on his car. His car didn't spin much if at all from a roll or even a dead stop, but I would have needed binoculars to see that guy if we had lined up at an intersection and hit it.

Anyway, he was nice enough to let me borrow his extra wheels with M&H Racemasters for some test/tune work one day, and after I popped them on I thought my car was BROKEN. It felt like a total pig, and the car would not even chirp the tires without extensive brake torquing.

I think if you have the chance to go to the track to do some test/tune work, you will really get a better idea of how well your car really runs by virtue of 1/8 or 1/4 mph speeds, and ET's..

If you still want to impress folks with wheelspin, get some cheapo hard as a rock tires on the back and go to town, or buy a turn-key 9 second quarter stage II race car. Cheap tires on your current ride will probably save you about $20k though..

Hey MAXVO2, Thank you very much for that info! That all makes a lot of sence. I think when I get the car where I want it (if Ever!) I will bring it up to New England Dragway to see how it really performs. JOE
