fuddle intalled et's down, but so are traps..?!?! I'm not a pro by any means but I'm not new to the 1/4 mile either, I know with traction et's go down and its not uncommon to see your mph go down as well... but, here's my issue. anyone with input please comment...
first trip to the track with the ss was last week, only mods where lid and drag radials... best run 13.45@103.?? I was happy with that, out side temp approx 75*
second trip to the track was today, only thing diffrent was a fuddle 3400 2.1 str. (which i thought would bring me about .4-.5 off the et.
best run was a 13.21@101.9 Now if this is a normal gain with out tune then I am very happy. but I'm worried about the trap, it was about 95 degrees outside today but I thought for sure that I read about traps going up with a stall installed? my 60' went from 2.002 to 1.8?? and my et went down a couple tenths but my trap did'nt go up it went down, now with the temp being 20* higher I'd say that was normal if I had done nothing to the car but with the fuddle installed i thought my trap would have gone up making it at least 103 if not more.... any thoughts on this? I'm a little worried, like I said no tunning once so ever shifts are slow as hell, traction was perfect, is this a normal gain, or am i being robbed of hp? thanks, steve....
also, I have never driven a stalled car before (always stick) the first couple runs i was launching the car from 1k rpms and netting 100mph trap speeds, when i went at 2000 rpms i got the 101.9... Am i launching the car wrong? do i need to bring the revs up higher? I thought the closer from idle you left the harder it would hit/flash to 3400.... thanks again, steve.

makes me feel better, I hope your right... however, my buddy was there with his m6 and ran 13.5 but at 104.... is that the m6 doing that for him? he has the same mods, lid and nittos.... (referring to trap speed)

thats more like what i have been reading around here... I thought I'd see 13.1 to maybe a 12.9 @105ish but instead I am seeing 13.2 at 101.9 wtf? I don't know what could be wrong... did you do ANY tunning once so ever when you installed your stall, or just got in it and went?

you probably need to adjust your shift points, i needed to with mine... have you noticed if your car is shifting at the right time? In terms of launching, each converter/car seems to like something different. Some like to just be flashed, others stall them up as high as you can. I usually stall mine up to about 1600rpm and then go, consistant 1.6-1.7 60's on bfg's Tire pressure/weather all makes a difference

brought it threw the gears shiffted at 6000 falls back to around 4800... I defently thing you might be right about bringing the stall up... like i said above, 100mph launching at 1k rpms, 101.9 launching at 2k rpms... about the same et, 101.9 was a little quicker.

thats cool, cuz if it had been 75* instead of 95* i'm sure i would have gone 103.... but i thought there would have been a gain... not complaining, just want to make sure something is not wrong is all.... I think I need to try launching at 2500-3000.

get a tune and get some seat time...and make sure that when your compairing runs that the DA and everything are similar...you really cant compare apples to oranges.. dont worrie the mph will come up. now mod that thang!

What kind of tire were you using? Are you sure you weren't spinning more?
Also, I've noticed with all the coverters I've had, in take some time/miles to break in.
Next time launch form 1000 rpms again and slowly roll into the throttle, see how that works.
You also might want to look into deleting the Torque Management.

using 315 nittos (drag radials) no traction issues.... i will make sure i look into getting rid of the tq management! thanks!

i trap anywhere from 110 to 107, i wouldn't base your car's overall performance on 3 runs with your new converter.
definately get your shift points tuned..if you're winding that stock valvetrain up to 6,500, you will have problems. drop them back to 6,200 or so and put your rev limiter at 6,300, no more. also, removing tqm (torque management) will put your tranny at a greater risk of failure, but should make you a little quicker. i've had my best luck launching my stalled auto from the highest i can torque it up without pushing the front tires, which for me is about 3,100 rpm. i have a 4k stall and 373 gears. also, if you dead hook your mph will be less than a slight spin off the line.

autodad,
my car almost done just what your's done after I got a tune so I could spray my car I went to our local 1/8 track
first run n/a 1.83 60' 7.87 89.2mph
2nd run spray.1.71 60' 7.24 96.9mph
3rd run spray. 1.72 60' 7.25 97.4mph
4th run spray. 1.76 60' 7.45 93.9mph
now on all these runs I tried to dupilcate everything burnout time between runs everything within reason....but I kept slowing down I did notice on spray that I didn't get the shift extension that I got n/a when it chages on spray it almost felt as if the tc or tranny was slipping so I kinda know how you feel.Both my tranny and tc are new so it's either one or the other.
