The motor may not be turning the indicated 6,900, but for best results you have to get as close to the limiter as you can without hitting it.
Apparently, you don't know exactly how that all works. 03-05 non-revups are electronically limited to rev only up to 6600 rpm's (called rev limiter). So, unless you got a reflash or have a revup (redline of 7000rpm), you canNOT rev past 6600 rpm. You can see in his sig and title that he has an 04.5. Thus, your above posts are incorrect in reference to this thread.

Now, the shift light is made to start blinking 500 rpms before the indicated rpm. So in your case, when you put it to 6900 rpms, it started blinking at 6400 rpm. So you had given yourself 200 rpm to shift before hitting redline.

If you don't believe me, go do a search.

Oh yeah, skaterbasist, just because you see a number that's lower than everybody else's, it doesn't make that person some sort of drag racing god. Don't believe just the numbers, but realize that regional climate conditions, track prep, car variables, and so much more can alter the outcome of a drag race. If you hadn't noticed already, most of the top times come from the east coast area. It doesn't make everybody there better than the rest of the US. Kissing *** online doesn't get you anything.

Thanks for the info, but I already knew all the things you just posted.

Im not sure what exactly your deal is, but im not kissing *** to anyone; never have, never will.

Just as you stated, most of those times are from the east coast. Yes, over here, its pretty much impossible to achieve such times considering our track conditions.

I never stated he's a "God", but its pretty obvious he's a heck of a driver. ( I don't even know the guy )

You're welcome. I already quoted you in my above post, so feel free to scroll up to see what I was referencing to. But I will apologize, as I was slightly out of line with such phrasing. I guess I'm just tired of all the seldom drag racers (read: noobs) thinking that all these east coast guys are the **** all the time when they probably can't do too much better than you when they're placed on the same track at the same time in the same car as you.

And yes, he's good, but he's no "different beast."

(I usually shift at 7000 rpm's)

I'll try shifting @ 7600 rpm's, see how it gets me.

The tachs in the revup g's are a little over-eager. I've used a techtom to observe the behavior. Basically the techtom displays one variable at a time, at a low resolution(like 500ms).

I learned that the tach seems to be almost dead-on in first gear. In second, it was off by maybe 100rpms. Third was off by almost 200rpms. And fourth was off almost 300rpms.

So when I hit the track, I used to shift at an indicated 7200 in 1st(I don't do that any longer due to problems with misshifts), 7300 in 2nd, and just a hair under 7400 in 3rd.

I understand, no hard feelings.

Quiet honestly, I'd love to take my G over to the east coast to get such outstanding times. But I wouldn't for obvious reasons.

Over here in Southern Cal, we probably have the worst tracks around (worst one being LACR; a very infamous track).

Although I am new to drag racing, I know alot of how it works. I still have not yet hit 2.1 on my 60 ft.

Thanks Trey,

Ill give it a try and see how it changes my times. I probably won't see a difference, as my 60ft's are very inconsistent

I also know the motor is not turning as high as it displays on the tach, and I watch the tach for shifting, the light just gives a heads up when it is closing in on the limiter.

I have seen the difference indicated on a dyno. When my tach showed a hair over 6,900, the limiter kicked in, and the rpm with the dyno indicated 6,600.

So yes, I shift just shy of the limiter , "at a tach INDICATED 6,900 rpms", even though it is really turning 6,600 rpms.

The light coming on makes the shift timing almost perfect.

Thanks for telling me the motor has a rev limiter, I thought a little fairy turned off the gas at 6,600. Oops, now I am being a smartass.

One more thing, setting the limiter at 6,900 gets you ready to shift ahead of the limiter, once it's starts blinking, as nobody has a .000 reaction time with shifting.

It's all about timing to beat the limiter, and being quick on the shift.

Well, then I'm glad I don't have a fcuked up tachometer. Mine is pretty much set where it should be so when it reads 6600 rpm, the rev limiter kicks in.

BTW, yeah, I used to believe in rev limiting fairies.. I grew out of that quick though.

i'm kissing ***

he pulls 1.9 60fts bone stock on an open diff

the 60ft doesn't affected by anything other than the driver and track prep, but it still takes one hell of a driver to pull a 1.9 even on the stickiest surface




ps
100 posts, woot woot

In addition to testing the tach on the dyno, I radar checked my speedometer.

The digital read out was dead on, the speedometer itself showed between 1-2 mph slower at 60 mph.

Factory gauges are infamous for being a bit off, and will vary slightly.

Anyway, I guess Santa Clause and the Easter Bunny aren't real. Thanks for ruining it for me.

Sorry, tire pressures were set to 27 psi, I tried to shift directly at 6600, but shifted slightly before it most of the times. My launchs were between 2500-4300 or so. On my launch I try to let out the clutch smoothly, but quickly, and ended up dumping it a couple of times, which made me spin through first. My clutch was sticking into second gear, so I had a small lag during that. Someone mentioned my clutch might be slipping.
