why did i lose

[xXxRocker5150]

both Jason and I said what you needed to do - did you not read our posts? Pretty much in short, you're looking at (if you want to go all out) new plugs, wires, water pump, belts, timing belts, and some misc. other things such as like a tensioner spring or something. I think twinturbo.net has a 60K service thread in the FAQ section.

First off, he's at a disadvantage from a roll because when you are going from a roll, you have to deal with boost response. From a stop you can launch the car (as described) eliminating this problem. For example...the 2005 Evo MR gets to 60 from a stop in ~4.8 seconds but takes almost 6.5 seconds from a 5 mph roll. Part of it is the traction but part of it is the turbo. You should have better odds beating him off a launch from a stop than from a roll.

You have to take into consideration that those cars, however God aweful annoying and common and boring (and on and on and on and...on....and.........) they are, the Mach 1 is fast. It'll get to 60 in under 5 seconds from the factory and he has mods. I know you do too, but I dunno man...he might just be faster...

[xXxRocker5150]

^ the reason I said roll is because machine shifts faster than a man, and I assumed he'd be in his power curve.

[youngvr4]

those mach's are tricky, there posted on paper as high 13 second cars, but they actually run low 13 seconds in the 1320

there monsters

[longlivetheZ]

They really are quite fast for a "factory" car.

Yes, an automatic can shift faster and more consistantly than any human could ever dream of doing, especially with a built up auto trans. But this doesn't help with slow boost response (lag) you're faced with in a roll. If anything, the AT will be slower from a roll than a manual cuz the AT will downshift once you punch it taking up precious time...you can already be in the optimal gear, ready to go if you had a MT.

unless you're already using the 1-2-3-4 gear things on the A/T shifter... but than it kinda defeats the purpose of having an auto...

Yea...meant to address this last night cuz someone brought up the topic of doing this before. I hate to seem like a disagreeable mother fucker, but doing that in a drag race serves absolutely no purpose.

Think about how a "traditional" auto trans is programmed to shift...

What happens when you floor it in an automatic? The engine runs up to its shift point, usually redline or close...the transmission's shift points are programmed to best use the engine's power anyway...why try to change that, and shifts.

If you're trying to use the stick to tell it when to shift, what are you going to do? You're going to floor it and go to redline or close, put it in 2, run it to redline or close, put it in 3, etc...it's not going to shift until you are past/at the programmed shift point anyway.

Get my point? I laugh when I see people try this in their...like...Cavalier, for instance. I used to know someone who used to drive around town like this! It was just funny. If you've ever noticed, when you're "shifting" with the thing and you move it to the next gear, it won't shift until you're at or past the programmed shift point anyway.

Their are really only three times doing this makes sense:

1) if you have one of those "Tiptronic"-type transmissions that are so popular these days. My '01 Prelude had one of these and, in transmissions like that, it REALLY DID do what you told it to. Even these systems vary when it comes to how obedient they are. Drove a PT Cruiser GT (cool little turbo PT...pretty fun to romp around in, honestly) once that had this type of trans. I was mildly obedient but still didn't shift till it really wanted to. However, my Prelude would NOT change gears on its own when you were in "I say so" mode (that's what I call it...lol). The only exception was if you stopped or slowed down a waaaaaaaaaaay lot (eg tried to go 10 mph in 4th gear, stopped in second, whatever), then it would down shift. You could literally scream along at redline in any gear of your choice for as long as you liked and let off the gas and it wouldn't down shift.

2) you are in the twisties or climbing a steep hill or towing a trailer or whatever and you don't want the thing to up shift when you let off the gas. Some transmissions are stubborn and will do what they're programmed to regardless of what you say. Most newer cars have an "O/D off" button so you don't have to move the stick to climb a hill or if you're towing something and don't want to use the O/D gear.

3) you MIGHT want to control the shifting if your car is modded and the programmed shift points aren't going to yield the best performance any more.

All in all, I would just let the thing do what it does and concentrate on launching and driving and all that.

long story short... auto's suck

[longlivetheZ]

lol...well...imo, yea...for the most part. They do have their uses, but as far as I'm concerned, a "true sports car" has a MT and RWD.

[xXxRocker5150]

yeapo, I agrreee with ya too LLZ, that's why I said that it defeated the purpose of having an AUTO tranny if you're going to use those things.

[k3smostwanted]

i didn't realize mach 1's were any different than GT's with different paint schemes. mostly because there are a few kids that have them around town that daddy bought for them and my buddie 350Z's with CAI used to run with them all day long, usually edging them out before 100mph.

i have spent some time at the track and i have never seen a Mach 1's pull better than a 13.5 and that one happened to have a few mods and awaiting a supercharger.

Interesting article. The 350Z wins the test but the Mach 1 is faster. This is a good illustration of why I don't like mustangs...they have a big ol' engine and that's about it...everything else is pretty unremarkable.

But ANYWAY...the Mach 1 runs to 60 in that test in 5.2 seconds. I bet the 350Z would hang with him pretty easily with a couple simple mods. I dunno why I thought the Mach 1 was faster than that (coulda sworn it was sub 5s to 60). This article...

http://www.motortrend.com/roadtests/...ch1/index.html

(I miss my damn link button like in the old format...)

...found it to get to 60 in over 5.5 seconds which is actually kinda lame if you think about it...the 350 will do that and it is a NA V6.

You know man...you should have beat him in a Z32TT...my bad...

[Hodo]

well the others are right, you lost because you lost from a standing start, it doesnt help you have a AT and arent sure how to launch it yet. It took me
about 5-10 good launches to find the right RPM to launch my NA from on the line. Its still slow but I can edge out a mildly modded SE-R from a standing start, and I eat them for lunch at a roll.

HIJACK WARNING----- After my trip to Charolette this weekend for a few things, and getting spanked by a modded SRT-4 from a 55MPH roll, I did start to pull on him when we hit 130MPH. And when we hit 150MPH I took the corners alot better than he did, man those SRT-4s are fast, but they handle like a minivan compaired to the Z. But I will say that his SRT-4 Stage 2 was just down right NASTY. Time for me to get off my ass and start actually making my car faster instead of talking about it...... Getting beat is what makes us go FASTER!

Disclaimer- I do not indorse late nite (2AM) sprints on the interstate....

[xXxRocker5150]

^wait, do you have an A/T btw??? at any rate, yea there was a guy in the 3kgt forums who wraped his srt4 around a tree trying to take a turn at 80 MPH... none the less he took that same turn at around 100 in his 3kgt and nothing happened.

[Hodo]

Yes I have a AT, I personally love it but I can tell you that a AT will lose more power to the wheels because of parasitic draw, than a manual. But a AT can handle more power than a manual transmission. A well built AT vs a well built MT. Stock for stock the AT will still handle more power. But you can find rebuild strengthend ATs for around 1500 and up, that will have less drain on the power and will handle insane amounts of power.

I personaly love the auto box, slushbox, girly gears, lazy boy, cars. They are more easiest to deal with on the day to day driving and not bad on the 1/4mile track. If you have a tip-tronic or slap shifter AT they are pretty good on the autocross and race track. If you need any advice on them just ask, I am sure I can find out if I dont already know.
