My 3000 converter goes to 0 rpm loss without lockup at the top of 3rd, so I get a full 6700 rpms cruising out with just my 26 inch tires, 3.29 gear... I hope to squeak out a 146 soon (just to beat up on a friend of mine).
The only way a converter can operate at zero slip is with a lockup clutch.
Had Pandora at the track for the first time since the new engine and transmission. Here's the scans of my timeslips. It was at Mason Dixon this past weekend, part of a yearly memorial meet with a (mostly Ford) group.
Thanks - I didn't even think about giving any details. Figured it would be easy enough to find my build thread if anyone was that curious. Though after all the issues with trying to learn how to shift the car, I can see why Jncomutt decided to go to an automatic. Probably would have been much easy to control the wheel hop/spin, plus not losing time to shifting (though a short shifter might help there).
As for slicks... man, I broke a tripod on the street tires... let's try to get that part fixed first. lol

Slicks will solve all your axle breaking issues... The wheel hop and shockloading goes away instantly.
I will say a 1.8 on a manual trans is about the limit of anything consistant... Going faster than that really gets to be hard on the 1-2 shift and the whole wheel hop issues in first.
When I had a manual trans in mine, poly control arm bushings got rid of my wheel hop. Ran consistant 1.75-1.80 60' times on 245/60r14 cooper cobra g/t tires until I left the diff on the track lol. Switched to auto and ran best of 1.69 on street tires. Went to drag radials and ran consistant 1.5x 60'. Lots of things affect wheel hop, I assume his build included poly control arm bushings but if not I would start there.

Yes, with the exception of the motor/trans mounts (solid mount to the cradle), all of the bushings in the car are poly (at least all the ones I know of, that bright red stuff). The clutch is a pucked (6? I think?) clutchnet sprung hub. I went with that to make it a little easier to shift on the street without as much headsnap. I'm still not terribly smooth at getting it into first from a deadstop. lol Fiero Store front and rear sway bars, coil overs with linear rate springs, sitting at stock height.
His car is listed on the first page under non forum members. Toronado transaxle, longitudinal setup. Looked at my video, it was a 138 mph, no ET on the board, but I seem to remember a 9.97. Next two runs were 9.81 and 9.77.
Today I disregarded my Dr's advice not to do anything that pulled G's because of bonespurs on my spine pointed at and right by the Aorta AND TOOK MY IMSA 427 to the strip today.I tried to take it as easy off the line as I thought I could get away with and still have good times.I also had the transaxle short shift at 6500 rpm rather than 7000rpm from first to second to keep G's down.But second to third it did shift at 7000rpm.So I know the car has faster times in it than it ran today. !st run, I was just checking it out and did a 1.975 60 ft,at 11.520 and 115.63 mph. 2nd run,I did a 1.649 60 ft at 10.597 and 130.28 mph. 3rd run,I did a 1.555 60 ft at 10.519 and 129.92 mph. Most people know what I'm running,but for those that don't this is what it is: The car was built as a street car and has working air conditioning and nothing was cut to get the engine in.The interior is stock except for a 6 point roll bar,gate shifter 5point seat belts and Auto-Meter gauges. It has an all aluminum 427 LSx engine mated to a built 2007 Impala transaxle with 3:29 gears and 10 1/2 3000 rpm stall torque convertor.And ab IMSA wide body with a painted Goodwrench logo design and white pearl paint.It has coilovers in the back. The engine dynoed at 621hp and 557 pounds of torque. The time slips are very light so I will have to darken them, I think ,to show up on the computer, and I will post some pictures and video's in the next couple of days. I hope this helps you V8 guyes out,now I know it CAN run the 9's,I just have to see if I have the guts to do it with my spine.

I kjnew your car was going to haul the mail once everything was sorted out....Waiting for video...
Blacktree,you bet I got the time slips,but they are real light and they don't show up so you can get a good read.I'm going to have to get the print darkend,then I will get them to you in the next day or two.Any ideas on how to darken them?
Got 'em darkened.
The transaxle is a 4T65E HD.My car number is 21 as you can see in the picture.Now that I can read the print I noticed they have the wrong date on the time slip,somebody got it wrong in the system.
Thanks, Don

That's right,two different cars.That Aldino still has the fastest times with a factory M90 supercharger on the 3800 and the car was at least 200 lbs heavier than a stock bodied Fiero.And it's been that way for years. Don
Shifting is killing you. I have 6mph on you in the 1/8th and only 2mph at the 1/4. Wish I could lock my converter, looks like lots of power to gain in the back half. Congrats, so close to 10s!
I doubt another track would help significantly.. I was expecting the 10 to come easily but there must have been a horsepower issue. I recently turned down the timing in order to preserve the head gaskets ... so I do believe we are just stretching the limits of a stock motor. I expect a cam would introduce another 50 to 75whp.
Short answer is operator error. I was shifting to 4th and hit 2nd. I just shut it down and coast the rest of the way.
I have a video of the run. It was against a new Camaro. It was my best run of the day. 14.0 at like 82MPH. Should have easily been in the 13 and when the car is tuned in a couple weeks I am thinking 12s. Assuming I learn to drive at some point. I will edit my first post in here to include the video of the run. I am fairly disappointed, but it was my first time EVER on the track and I've only had the car 1 week, so lots to learn about driving it still.
Wow, you really need some drive time before going to the track. It can be easy to shred the trans when your adrenaline pumping first time at the track. It should do low 12's all day.

. Just happened to be at the track and saw the runs.
shits slow.
