This dude in a talon ripped me up yesterday....but this guy was so into his car, you could tell he's never seen a boob in his life lol. when i said good job, he looked the other way. my question is, what is the best way to shift an automatic off the line? Stupid question, I know....but all I do is just gun the b*tch...and I'm thinking there might be a more efficient way to get higher RPM's with an auto. (without hurting the tranny)

Thanks a lot

 

Sorry to hear about the loss. On the auto the 700R4 will upshift from 1st to 2nd even holding the shifter in 1st. So it is best to start in 2nd and do the 2-3 shift manually. Note that L03's lose power at high RPM.

RBob.

 

even if you dont have a stall converter hold the brake, bring the rpms up too about 1500 then mash the throttle- of coarse you have to let off the brake, but that should really help you with your launches, because you will be that much more into your power band than at idle get what im saying?

 

Isn't this a post for the racing board?

 

Yeah it is. Was it a turbo one? Although I have a feeling even a NA one might have a chance at beating a LO3

 

not even close. My gf has a 98 eclipse gs and it isn't even a contest. They are 18 second cars.

 

It's been my experience that manually shifting an auto doesn't do a whole lot. Just put the thing in "D" and powerbrake the thing like somebody said.

 

At the track I dropped 5 tenths, yes that's 1/2 a second, by manually shifting my L03.

 

dont power brake it, stall it up.

 

Well, like I said, it's been my experience that it did nothing. But then again, I have a vette servo, and a trans-go shift kit in my new tranny, so maybe that has something to do with it.

For me, put it in D and go.

 

Just to clear things up, when left in D, my car will shift at about 4300-4400 rpm. I manually shift at 5,000. I attribute the 5 tenths to shifting higher, keeping the car from dropping out of it's power band, not from manually shifting alone. If I had manually shifted at the same rpm it shifts itself, I assume I would have ran the same times. Just thought I would clear that up.

 

After putting in the trans-go shift kit, my tranny shifts at exactly 4500 RPMs everytime when at WOT.

 

i manually shift my auto at 5500. Car still pulls into 2nd just as hard as shifting at 4500.

i dont recomend this however, unless you are trying to kill your l03 as i am since i have a new engine ready for it .

i attribute the modified throttle body, full open exhaust (no cat no muffler), and some chip tuning i did to me "not" loosing power at high rpms. It does die from 5500 to 6k though

even though its a tiny cam, it sounds sweet at 5500 with the exhaust how it is. its just screaming.... screaming, shift damn-it.

 

i dont think thats as bad as what i do. I like to slam it into first and punch it. Love that feeling. Get rammed up against the seatbelt from the engine braking and then get slammed back into the seat when i gun it after the shift. Gotta love that 3.08 ratio first gear. Even with the highway gears it still pulls real good in first.
