New Best Tonight Went to our local track tonight to make a few passes since I have not been in a couple of months. Wanted to try out a "Jake's Performance " black box manual controller for my 4L85E tranny and see if some 26" tall M/T drag radials would make any difference since my nitrous converter & 3:73s are not a great combo for motor passes.
Improved all around slightly on 60 ft time, 1/8 mile, and 1/4 mile increments. Not too bad for a compromise combo and being able to drive it 75 mile round trip to track and back.
Shifting the tranny manually is not quite as consistent as letting the computer do it, but it was easier when swapping tire diameters and not having to make up a tranny tune at the last minute. I bumped the rev limiter on the 2-3 shift on the 4th pass and even at that the MPH picked up to 129.01 mph
Best two passes:
1st pass
60 ft---------- 1.5711
330 ft--------- 4.4474
1/8th ET-------6.8521
1/8th MPH---- 102.46 mph
1000 ft ET---- 8.9254
1/4 mile ET--- 10.6829
1/4 mile MPH- 128.57
4th pass
60 ft-----------1.5819
330 ft----------4.4499
1/8th ET-------6.8564
1/8th MPH-----101.67
1000 ft ET-----8.9334
1/4 mile ET----10.6851
1/4 mile MPH--129.01

On the engine dyno @ LME it made right at 650 HP and 580 Tq. Once installed back into the car I had Pat G. do the tune and on the Chassis dyno it put down 542 rwhp and 521 rwtq. That's through the 4L85E tranny and Moser 12 bolt with full spool & 3:73 gears.
The car was built as a dual purpose setup, to be able to be street driven on 93 octane pump gas and be able to make decent motor passes and make some good blasts on a 150-200 shot of juice every once in a while. I am so tempted to send the converter back to FTI and get it loosened more for a respectable 60 ft time on motor and put the old 4:11 gears ( or 4:30s ) for an all out hero pass and see what the engine is really capable of pushing the 3800 plus race weight to. I think it could possibly run some 10.30s or so.
I'm gonna play with it a little more and then put my nitrous tune in and see the FTI nitrous spec converter earn its keep. The 3:73s don't let me rpm through the lights high enough on motor ( about 6100 ), but will also shine once on the giggle juice.

Did you compare to a 28" tire? I am in the same boat, i have a 4500 nitrous converter and 4.10 gears with 275x60x15 pros. Need to try 26" with this nitrous converter being so tight . I like how it drives with 28 on the highway though

I know the car is gonna run good on the nitrous, I'm just really wanting to get it down on the lower 10.30-40s on motor before I start spraying it. If I would lighten the car up it would do it pretty easily, but I told myself I wasn't gonna rip this car apart as its too nice to do that to it.

Thats where I'm at. Want 10.9s on motor and then what ever it does in 125 shot after is a bonus.
The nitrous converter is more for efficiency while cruising.
It flashes to 4500 but only pulls 1.60 60 ft on motor and falls 1800 rpms on the shifts. 7100 to 5300ish.
I think on motor a 26" Hoosier drag radial would be key for me.
I tried my 295x45x17 mt drag radial but it didn't hook. I will try them again on the 17th.
Your car is running strong man. Congrats
I just picked up some Dart 225s to put on mine. Probably going to get them ported and then put on in search of 10s

I have an extra 4L80E tranny and I recently bought a TCI Low Planetary gear set from a member here on tech. I think I will have my tranny buddy install the lower gear set in it and see if the 2.97 1st gear and 1.57 2nd gear will help get this ole heavy pig up and rolling out of the hole a little quicker.
I am hoping that the more aggressive gearing in the first two gears will enhance the 60 ft & 330 ft times on motor seeing as the 3:73s and the 2:48 1st gear in the 4L85E are just not providing enough gear multiplication to launch this ole heavy car. I really hate to go too loose with the converter and kill my nice drivability and efficiency and I know the converter will earn its keep on the juice. If anything I may get it loosened up just a tad bit.
The 2.97 1st gear ( gear multiplication ) will be like launching on 4:30 gears, and the 1.57 2nd gear ( gear multiplication ) will be like having 3:90 gears and of course when in 3rd gear the 3:73 gears will let me be able to achieve somewhere around 145-150 mph at my 7000 rpm limiter.
That's gonna be my next plan of attack. I hope to be able to achieve some where in the 10.30-40s on motor and then see where 150-200 shot will get me.

I think its a combination of the tight converter, the 3:73 gears and the 2.48 1st gear of the 4L85E tranny. Way less torque multiplication than your run of the mill 4L60, 4000-4200 stalled, 4:11 geared lighter cars.
I'm not disappointed in its performance, but always want more. That's what happens when you try to get the best of both worlds. The car becomes a compromise effort either way. I will try the lower gear set in the tranny and possibly loosen the converter a bit.

I see you keep whittling down the time slips on your car. The ole car is hauling pretty good. I would kill to have your 60ft times
But everything comes with a cost. I saw where you say you calculated your converter slip around 13% or so. Mine is too tight for a all out motor pass, but has a pretty nice 6% slip, thus the mediocre 60ft time
Yeah the 3e is loose but works well. Hoping to be at the track this Friday again. Had alternator issues with it last time and I took some more weight off the front of the car.

Thats what I like about my car as well, no hassles of loading it on and off of a trailer. Gets to be a chore after a while and takes some of the fun out of it. I like driving to the track, lowering the psi in the drag radials and click of a mid 10 sec pass and then drive home.
So, since your speed density tune with Pat G. do you have any new dyno #s ? Just curious if the tune picked things up a little by getting rid of the mass air sensor in the intake tract ?
Good luck Friday night if you make it there and be sure to give us an update.
