i was just wondering, right now my shift light is set to 7800(i was thinking that by the time i actually shift ill be at 8000), but is 7800 our peak HP? the specs say 170@7600RPMs i know thats not accurate but am i gaining anything by shifting later? just wondering

 

Never fiddled with a shift light on our car but I have on my drag car:
I set the shift point about 200 less than what the peak horse power, I dont know why I did that but it seemed to work out to my liking.
Anyway I shift in our cars around 7600 so try setting it there...(that is when I am revin' my engine that high )

 

170 hp at 7600 is accurate...reason to shift higher is to land in the powerband

 

so should i continue to shift at 7800? because sometimes the limiter comes on before 8100, iv see it come on at 7900 even (once it came on at 6800, i was low on gas...)

 

If you have it set to 7600 and you really shift at 8000 thats gonna land you higher in the next power band. I shift at 8000 in my GSR...

 

good time... was that on a fully stock car?

 

if i were u i would shift right before fuel cut....which is around 8 200 on a gsr i believe. I shift my ITR at 8 700 when racing.

 

well 7800 is the highest shift pill i have, so i guess thats OK, i was just wondering

 

I've seen a few different posts of members saying that their cars limiting at 7800/7900/7600 whatever, i drive mine to the redline every day and it has never come in sooner than 8100/8200....what causes it to come in sooner...or are their tachs way out of whack??

 

it has to be the tachs, because i have fields unit and my car never hits cut off before 8200

 

All I can say is Redline!!

 

7600-7800 is perfect counting the little delay you have from seeing the light and changing gears, so sounds perfect

 

okay ill leave it at 7800, and the time that my limiter came on at ~6800 was when i was bone dry on gas and had the AC on(im stupid )

 

the fuel cutoff has no contact or communication with the tach...the tach is simply the readout of the engine speed so it wouldn't be the tach. but, my friends 94 'lude did the same thing, regardless of full tank/empty tank....and it would do it randomly. I've never had that happen...my car is non-VTEC, my buddys 'lude was VTEC, maybe that has something to do with it...who knows?

 

would it matter if the car had JUST warmed up

 

To my knowledge it shouldnt have came on at 6800, no matter how long its been warmed up. It never happened to me atleast(yet). It could have something to do with VTEC... like your ECU saying "****, the motor isn't warm enough yet, I can't engage VTEC, time to shut down".

I'd say 7800 is the ideal shiftpoint for you so you wont hit the rev limiter. It definatly sucks when your at the track or smoking a civic and your rev limiter hits. That way you have 200 rpms to get into the next gear.

i've learned to always shift at about 7800 RPM... cuz when i rape shift.. my rpms jump up about 200~300 before i change over to the next gear.

 

that little display of light only take .5 secs to react to it

 

1st......... 8100
2nd........ 8000
3rd........ 8000
4th........ 8000
5th........ gotten it up to 7000

 

is rape shifting your term for speed shifting?

 

I usually shift quickly right around 8K seems to work for me..
