whats faster in the 1/4

and yes, supra autos are quicker in the 1/4 than supra manuals, on turbo charged cars, autos can build more boost off the line than a manual can, and also an auto can hold boost in between gears. Now the reason mitsubishi never made auto an option in the VR-4, is when you have an AWD car, there's really no reason to have an automatic,

Not quite. Cars don't have 4wd, it's called AWD, difference being that 4wd is switchble whereas AWD stays obn at all times. Now getting back on topic here, the automatic turbo will be smaller than the manual turbo in most instances. So automatic will hold better boost but not enough power to overtake the manual car (and we all assume that the guy driving the manual knows how to shift properly)

I still don't.... How should I learn to take off into first real quick withought spinning my tires?

That's sad....what an idiot.

according to what i've read, brake boosting can be a deadly enemy to manuals everywhere from us autos, however it would have to be a fwd tt converted 3000gt to brake boost (glances at hotshot). ALSO the shift kit for our autos apparently makes a HUGE difference in our shifting in that the shifts are as quick as possible if set up right and eliminate quite a bit off of our 1/4 times, nothing as amazing as a tt conversion but still enough to make you happy. Lets not forget us autos still have a little bit of control if we choose to (its nothing like having a clutch and a 5 speed but we have L, 2, D od off and D od on) and i know of people who have been manual shifting off and on in their autos for over 100,000 miles and still no big issues.

Hrrrm, wish I could try out this short shif thing. Anyways I dopn't plan on haveing this car for too long, might sell it sometime during the school year, I want to try to find a good VR4 but there is only one on auto trader within 300 miles of me! Seems like they all got snatched up just before summer began, when is the best time of year to look into buying a VR4?

[igota20hpweedeater]

well, in theory an auto might be better in the 1/4 mile for turbocharged cars b/c during shifts the auto will maintain boost and the manual will have to build the boost back up after shifts. But my question is why do all the car and driver people clock faster 1/4 mile times in manuals rather than autos? I think its b/c manuals are better for the 1/4.

[B00stCreep]

Don't manuals have the advanatge of shorter and closer gear ratios that keep them in the car powerband more so than an auto? I thought thats where they had the advantage

[Hotshot8792]

on two wheel drive cars, autos generally get better traction off the line, on top of building boost

manuals have shorter gears, but i have come to discovered that the shorter gears on same cars dont make that much of a difference unless your just an absolutely great driver

on N/A 3/S cars, the reasons manuals are faster is cause the autos can't get off the line quick enough, now, i've seen an N/A 3/S auto race a N/A 3/S manual from a roll, and it was a dead even race

and yes, the shift kit does make a difference on auto cars, to put it like this, when i raced at the track, i could spike 5lbs of boost between shifts because it took that long to shift

as far as the automatic vs. manuals go, its really tough to say, just like on close races, it comes down to the driver, well, i guess when you compare the two cars, i guess it would all depend on the driver of the manual and the set up on the auto, or something like that. Its tough to say, i've put buslengths on a 6-speed VR-4 from an interstate pull before, only running 7 psi (10:1) to redline because of a boost leak, but then you'll have to look at drivetrain losses, and i had a full exhaust and LS6 MAFT, and he was probably completely stock (12 psi, 8:1)

I will say, BPU will make a big difference, one of my friends stock VR-4 trapped @ 76 on the 1/8 mile, other friends BPU RT/TT trapped @ 82, and although i trapped @ 86 on the 1/8, BPU had .3 seconds better than me on the 1/8 and stock VR-4 had same ET.

So as you can see, its hard to just say which transmission is better. A manual will definitely get you more control for sure, but an automatic will get you better consistancy. All i know is i'm just trying to see what an automatic is capable of doing, and i'm sure there will always be a 3/S manual out there much much quicker than me.

straight line with equal traction and power, an automatic is faster in my experience.... my bros 99 GTZ galant is crazy stupid...on the freeway, at 80mph he rammed the accelerator to the floor and the damn tranny shifted to 2nd gear for a second or 2 (straight redlined) and then he metered in third... I never ever thought the ECU would be so poorly programmed that it would rather detroy the engine to get the car to haul ass... my other V6 is a 2000 Accord, and it never does that when I go all out.

Straight line, autos for sure.IMHO

[Hotshot8792]

last night, at the street races

Camaro SS automatic vs. Camaro SS 6-speed

i saw the automatic barely edged it out

[igota20hpweedeater]

well, im confused...not really but i just have one question. For sport car stats y are most of them recorded in manual cars instead of in the auto? Wouldnt the people who record the 0-60 times and the 1/4 miles want the fastest times?

[GrungeAholicVR4]

Actually, not to burst any hard core manual fans, because I have a 6 speed VR4, and i love manual transmissions, but, it is a very common fact that the fastest drag cars have automatic trannys. Pro-Stock Draggers, and Pro-Comp cars, were talking 5-6 second cars, use 2 and 3 speed power glide transmissions. They are similar to sports shift, or t-tronic shifters, still automatic and clutchless, they all have Torque convertors... I used to have a 69 chevy p/u before my VR4, it had a turbo 400 racing automatic tranny with a shift kit, the shift kit enabled me to program where the tranny shifts, and how firm, or soft it does it. It shifted faster than any manual I have driven, or seen driven...and it still had nothing on power glides...

The only place a manual is better than a good automatic is on top end highway runs...and still, its not by much..

[igota20hpweedeater]

yeah i know with torque converters autos will easily be better than a manual, but stock for stock which is better?
I have noticed that my manual 300zx is faster than my auto one, by feel and by the g-tech stats.

dont always base everything on how it feels when you drive the car, gear ratios can be deceptive

shorter gears (which are found in manual cars) will make any car feel faster, yet, does not necessarily mean that it is faster

for example: my buddies WRX feels much quicker than mine, yet, everytime we have raced, i walked him without any problem at all.

I think manuals are fun cars to drive, and as far as drag racing, i honestly think it can go either way, all depending on the set up of each car.

hey how much to put a high-stall torque converter or shift kit on to my auto gt?
