found out our rev limit is not 8300rpm !!

[harrison888]

FYI.

Couple weeks ago I put in my new Pivot digital tach w/ shift light, (model DTML), on the tach module, it has 3 buttons, the first one is RESET, the middle one is to adjust shift point (from like 2k to 12k), the third one is PEAK, which shows you the max rpm you've been to. So last night I was beating the sh!t out of my car, then I was checking the peak point, guess what, it shows 8404 !!

[GTS LAID]

i think there were a lot of people that already knew that... but thanks for hard confirmation...

[Willis5050]

I didn't know that....Good observation. I don't know much about the Pivot tach, but i assume it is pretty accurate, no?

[djm221]

You should get one of those on the 2002s, see how they got it :chuckles:

[icyjaws]

actually if you do a bunch of runs you'll see you get slightly diff numbers. i think i got anywhere from 8250-8350 w/ the AFC when i had it.

[jdm-style]

wow....the 8000rpm range.......one of these days.....

[harrison888]

Today I hit 8441 rpm !! what a nice engine

[oo_snoopy]

Stupid auto GTS, i want to go over 8,000.

what, the sig? or the auto over 8k?

i'll check out what my afc says as max on my way home....

heeeere meestor rev leemeetor

[larryd]

hmm.. i think I only got mine to 8298 if I remember correctly according to the AFC

[00CericaRuss]

well.. i tested it on the way home, and my afc caught the reading of 8313 when i bounced off the rev limiter in 2nd gettin on the freeway

[ghostface]

hey does the gt-s really still ;produce power all the way up to 8400 rpm or do u guys just like the soubnd of the high revs so u shift there....just a question...

What is the resolution spec on the gauge?

[supercarman]

how do you read the peak rpm off the afc?

[00CericaRuss]

you need to go to single channel monitor mode, select revs, then... i think you either hit the up or right arrow.. and a little box w/the max rpms should pop up and adjust the further up you go

[Bryan H]

mine, dyno proven was 8390
id be more apt to believe a dyno then a afc or an aftermarket tach

[spaldam]

My question would be whether or not it's still makeing enough power at that RPM to make it worth it, or should we be shifit just as soon as we can to hit the 6000 RPM mark.

the higher, the better. you have to shift nearly right off the rev limiter on the GT-S. horsepower peaks at 8000-8100rpm with an intake.

A valid question. The biggest problem with the GTS is the small powerband and the transmission that is too wide for it. Any rpm ceiling increase would help the performance of the car. I'm talking about total performance, not just drag racing (which the car sucks at anyway). You're probably making more HP at 8700 than you would be at 5700 when you fell out of lift on the shift. If Toyota feels the need to rev limit to ~7800 on the 20002, they should toy with moving the VVTL-i crossover to ~5500. That would clean up most of the performance issues with the car. Then the Celica would have an engine that matched the gearing of the 6-speed transmission.

[ghostface]

the reason why toyota makes theere ecu's the way they do is because all toyota celicas are NOT going to be in the hnads of performance enthusiasts like us....toyota is a major corporation that is tryin to sell a produc to the most people maximizing thier profits...they dont give a sh*t about wether or not you can win races because of where your rev limit is and how good u are landing in lift... all they care about is that they sell thier cars to as many people as possible....this is why they do these things...think about it...many people who buy the gt-s have no idea what vvtl-i is .they just buy it because they see that it looks cool and that it has 180 hp...they have no clue how the f*ck to get that hp out of the car....then think of it this way..say u are a woman lets say late 30's and u bought a gt-s and one day you are driving and u rev it pretty high..and u have no idea what vvtl-i means then you feel the lift kick in..this woman will have no idea what the engine is doing and will assume her car is f*cked.....basically toyota makes there cars to be able to sell to all different types of people....now TRD IMO should make a computer for the gt-s so the owners can have as much freedome with thier cars as possible..then from trd's standpoint they will never do this becasue of too many problems and and they will have to warrenty all of this....TRD is a division of toyota to make soem more money on thier cars....from a finacial standpoint..it will never be worht it to toyota to make soemthing likethis if they have to keep fixing all these problems that it will cause....(sigh) god i hope u guys understand...thanx dont mean to casue any problems..just an explanation..

[Red-one]

I got mine 8667rpm's......2000 GT-s....

[2000 XYR]

I'd bounce off the limiter all the time in my auto, at 8000 RPM or less. I never actually hit the rev-limiter in my 6-speed. I was sorta scared to because once I reved it to an indicated 8400 RPM and it hadn't bounced off yet, it freaked me out and I shifted. I was scared to try for higher. This was on an early production 2000 model.

Peak power is typically still right around 7,600 with an intake. The reason that it is better to shift higher is to land in the power band. If the cam switches back over when you shift because you let the rpm's fall below the 6,000rpm switch over point, the power instantly takes a 25 - 30 hp nose dive. It's like God just slammed the brakes on you.

I noticed that immediately while test driving a 2003 Matrix XRS yesterday (which obviously has the same basic engine as the GTS). It was very hard to stay above 6000 rpm on the 1st the 2nd shift. In fact, even when Id bounce it off the rev limiter (at an indicated 8200 rpm), there was still an obvious "lag" at the beginning of 2nd until the revs hit a little over 6000 rpm.

The car was fun to drive though. I just wasnt used to having to flog a car so hard to get it to move. (my daily driver is now a 2000 Maxima SE.) Below 6000 rpm, that car was as slow as my automatic 4 cylinder Ford Ranger! From 6000 to 8000, it surprised me.

Its quite a good buy as well. A top of the line XRS with the 6 speed can be leased for under $300 a month on a 3 year/45,000 mile lease.

[mac340]

Does everyone make a habbit of hitting the rev limiter? I have had my car for 2 years and hit it twice both times by accident, but i still manage to stay on lift when i shift to 2nd. If your trying to be as quick as possibe i would think hitting the limiter would just slow you down, right?

[chameleon]

Yes, you are right. The trick is to shift right before fuel cut, it's just that a lot of people seem to miss judge and hit it by accident. When these guys shift, they are not trying to actually bounce off the rev limit, they are trying to shift just before that.

I usually don't actually hit the rev limit either, but sometimes I do by accident.

I was hitting it on purpose to see where it was!

[VVTL-i-KiCkIn]

I own a pivot tach too, and they are pretty accurate but,

because after market tach is sharing wire with stock tach..
it is sharing the signal, so it might not be 100% true....

So, disconnect the stock tach. You don't need it if you have an aftermarket one, and it's not going to mess anything else up.

well I thought about that too, but it would look weird, if one of the needle is not functioning.. also it looks more fun, if more needles moving up and down..

[Sups]

reline 5th and drop it in 2nd.. you'll get a higher rp reading. kidding of course

no.

with an injen cai and maybe trd exhaust as well, the peak power moves up to around 8000-8100rpm. dynoes show this, ask larry i think he had a few lying around.

when i first got my car i accidently went from 3rd gear redline to 2nd instead of 4th. it revs pretty high... lucky i didnt shoot a rod.

fyi, a dyno is just as accurate as any aftermarket tach or afc... all they do is clamp a wire to one of your coil packs (or spark plug wire) to read rpm's...

i disagree... the transmission on the GTS is perfectly matched to the engine. just because most people can't fully take advantage of it (i.e. not have the ability to drive the car properly) does not make it "a problem". and as far as sucking at drag racing, i fail to see how my consistent mid/high 14 second GTS on just a cheap CAI and weld on muffler, can suck at drag racing... heck, most type r's i see at the track have a hard time breaking 14s with a lot more mods than my car. but of course, since it is probably due to their sucky drivers, then i guess that also makes the type r suck at drag racing...

i dynoed my 2002 GTS 6speed and made my highest hp (167.4) at 7800........the curve looks like it woulda went a little higher too
http://wtfbracing.com/forum/album_pic.php?pic_id=621

so my question is......at what RPM does a GTS with intake make peak HP? in my case it looks like over 7800 (where i cant hit)
