Shifting question!!

[kuruption1983]

ok i have a lil question!!<BR>This is the first time i post in engine forums, so you should know, i know notin about racing and crap!<BR>but i wanna know what are the best times to shift.<BR>i have a stock 94 GS base, and i want to know what is the best RPMs to shift @ different gears, cuz i know if you kinda go over a certain RPM, the power starts to come down. And i know this, that GS precidias, get their magical power @ 4k RPM.<P>sooo i would appreciate any info in this shifting matter, in case i might have to use it somewhere and make MX3 community proud! LOL<BR>( i am getin my other car with bodykit, so no racing for me,)<P>anywhoz, thanx for all replies in advance!

Normal driving I shift between 3500rpm and 4000rpm.<P>Racing I shift at 6500rpm. [img]shrug.gif"%20border="0[/img]

Like it was said before (read this thread: <A HREF="http://www.mx-3.com/cgi-bin/ultimatebb. ... 2&t=000107" TARGET=_blank>http://www.mx-3.com/cgi-bin/ultimatebb. ... =000107</A> it's best to shift pass the redline (7700RPM) to get the best times possible with the K8 (V6 engine).<p>[ October 22, 2002: Message edited by: Shadow_Mx-3 ]

Peak horsepower is at 6500 and redline can vary above 7400. Its never good to shift once you hit redline. Though since there is only about a one thousand RPM difference and the little K8 can take a beating, even at redline, and come back generally unharmed, then shifting anywhere in between will give good results.

1st @ 7000+<BR>2nd @ 6800-7000<BR>3rd @ 6500<BR>4th @ 6500<P><BR>It depends on setup , the more high flow system the higher the peak horsepower<P>the goal is to bring the motor back to peak torque which is approx. 5000<P>thats what works for my setup.

Those are some high shifting rpms.... I would be to scared to push that little motor pass 6500rpm :p

[zevirii]

I know nothing of technical data on the engine such as rod ratios... But how far can it be pushed and not hurt the engine at all?

I was shifting @ 6500 on my GS and not holding out 3rd till trap. My best time was stock 16.8.<P>Afte talkiing with Dave, He suggested maybe 7200 or so, and that I did. I pulled a 16.6 and a 16.5. Seasons over this week, so I may try and get to the track tonight. Try and pull some <16's. I'll try and hit 7500 or so, see if that improves. My GS is 100% stock. Ive gutted the interior, but othe rthan that. Its all stock. I have put a different OEM clutch in there, just cause my clutch was slipping a bit. The clutch is not new. I didnt feel I needced a new one, since Im going to swap the 2.5 soon and will be getting a new one anyways.

You're safe at ANY rpm in that motor.

i found that by only taking my foot like half way off the gas in-between shifts helped get it in and out of gear quicker and gave it a little more "oomf" coming out of the shift. i shift close to the redline ne way but using this technique has tested the rev limiter once or twice.\<BR>anybody else do this or what?<BR>fyi this is on my sohc and definatley not for street driving(just track).

Shady, I shift that way all the time. And it sure works for me!

I find that when leaving the gas in it makes it harder for the clutch too grip, thats probably just the way i do it though, oh and when im city driving i usually shift at 2.5 and when I feel like giving it which I almost never do I let her red line" and those gears just breeze to the next.

driving would be best between 3000 and 3500<BR>racing:<P>Launch off at 3500-4500 depending on your setup and tire status..shift into second at about 7200-7500 go to third about 6900 - 7200 and then shift into forth about 6500-6700...I got a stock GS with a fireball muffler and prm cold air intake did 15.9 1/4 mile (90 OCTAINE gas not that it makes a difference i think)
