manually shifting an automatic??
Hey just a question for the experienced racers w/ automatics:
If you are manually shifting what is the best RPM to hit the shifter?
I was practicing on a country road in prep for going to the track and it seems there is a delay between moving the shifter to 2nd and when it actually shifts...
needless to say i shifted pretty high RPM because I didnt realize they delay and thought it would shift immediately. any suggestions would be appreciated!

Personally I tried manual shifting when i first started racing but found that I could never duplicate the same shift point. So I never shift manually. If you do want it to shift at a higher rpm than the stock shifts you might want to consider the Suprastick.

Is that a shift kit? Is it expensive/hard to install? Im gonna do some research right now. Is there any way to modify the ecu to adjust the shift point besides the TC ecu mod??
keep it up and practise, u can only get better...

Im practicing these shifts on a country road as soon as I get off work... hopefully I can get this to work before the track opens.... But if it shifts faster for 1-2 than 2-3 should I try reversing these numbers - 1st at 6500 and 2nd at 6200-6300? what do you think?

No... 1st gear is torqier and the Rpm climbs faster, when u shift at 6500 you will be miss shifting due to it taking that very slight delay, 2nd and 3rd isnt so bad, it wont climb as quick and the delay wont really matter

So I just got back from the track.... a little disappointing. I lost both races first an rx7 and then a suped up RAM 1500 (pretty sure he had forced induction). I ran 16.18 and 16.24...
The manual shifting didnt work out for me. I need to practice more before I go again. My 1-2 was right on but when I did the 2-3 it just didnt want to shift up... I was climbing too high in rpms for my comfort zone and just kept climbing... I had to let off the gas before the end of the run because I dont want to risk any damage to the car...
I will continue practicing as the manual shift run was the better of the two even though I let off early... I think I will benefit if I figure out how to make it shift were I want.
Does it sound weird that it didnt shift up? should I just let off the gas a tad to make it shift or something?

^^^ for you it will be an emanage or Utec, for us 5.5 its Technosquare... nzelinksy doesnt matter how far up in the RPM you go, if its too far up you will just hit your rev limiter (basically miss shifting), no damage will be done, if 6500 didnt do it for ya, try 6400 IIRC 5.5's have a 300rpm error, so even shifting at certain RPMs it would go the extra 300rpm (IDK if its all 5.5's) but keep on the gas bro... seems like you could've broke 15's on the runs... whats the 60'?

no I havent done anything except my intake.... Does the stilling grounding kit do the knock sensor? or can I just buy some regular wire and do it myself? what would you reccomend?

could I be running 16's with a bad MAF? I mean the car doesnt feel slow but compared to other 5.5's I guess it is... Should I try the CNC cleaner or replace it?
Do you guys know anything about using a bigger MAF?

Y do you think it didnt shift though? 60' was 2.5 on the first run... What happens if you hit rev limiter in gear?

tires are a big problem for me right now... I have Nokian winter tires. They are pretty much brand new I have about 70% left on front and 90% on the rear. I think I might try using the traction control it might help my launch, Im just worried that it will cut too much power and make me slower.
We have snow on the ground for usually 7-8 months a year and it gets pretty bad. Im waiting till next spring to buy rims and better tires since the seasons almost over now Im not spending the money...

do you think traction control will help my launch? I've been turning it off all the time

hmmm sounds decent. I can't afford that right now either though...
I was thinking of replacing my thermostat with one that has a cooler temp so the fan comes on sooner. That or hooking up a switch to turn it on manually... what you think?

Hook up the switch. Thats what I have. It helps alot with cooling the car off.

You dont have to buy a thermostat you can mod the one you have by adding a spacer to it. Check JIME's website for the how-to.

Same here. 6500 rpm on the 2-3 seems to make a noticably difference in how the car pulls in 3rd, since our 3rd gear is so long. If I let the car shift for itself, sometimes it short shifts into 2nd at 5800 rpms.

Bad MAF means no power above 2500 rpm, you probably couldn't crack the 18s with a bad MAF.

any suggestions?
if u dont run it, i sure will lol, just got my obx headers

87 mph? Something is definitely wrong. Bad spark plugs can hurt performance but probably not that much. Could be clogged cats, problem with the throttle body not opening fully, bad knock sensor pulling timing back too far.
