I had posted something about this but it got moved to drag racing board or some **** like that. anyway, I read somewhere that shifting passed 6000 or so rpms is pointless in my car. anybody hear anything like that? one tenth of a second faster and ill have a 13 year old car with less than 100hp at the wheels and 100k+ miles on it in the 15s. Any advise would help actually.

 

go till the power drops off,mine does at 6900.theres no point in going over where the power runs out.

 

Actually, there is.

If you shift to the next gear, you lose a ton of effective torque at the wheels. You only want to shift EARLY (before redline) if torque drops off so far that you have less effective torque at the wheels than you would in the NEXT gear at target rpm for the current vehicle speed. Given the characteristics of our I4 engines, peak torque is always made pretty high and remains decent all the way to redline... so shift at redline.

Yes you can feel torque drop off, but it will drop off even more if you shift.

you have a point there also!

 

i have a 89 dx and i shift at around 7000 and i have torque all the way into next gear, and i have high end power all the way to fuel cut, i dont know just my 2 cents
my car pulls 16.6s in the quarter

 

Your DX pulls that high? Even my Si would fall off around 6400. God I loved my Y8...pulled all the way to 7200 rpm. 15.2's!

 

nice 1/4 both of you. i shift at 7k in my si. 15.2 on the mini me is great. did anyone happen to get the Honda Tuning issue with the integra with the vortech supercharger? he ran a 14.9...wtf??

 

i shift about 6700-6800 the most in my d16a6...but usually around 6500 though...

 

yeah 6500
anything above that it kinda falls off. i find it pulls pretty god dam good from 5-6500

also what do you guys shift at daily street driving? 4k?

 

Fuel cut stops the fun at 6500 rpm.

 

as explained above, it may lose power towards the top, but if you shift early, youll lose out the poewr...i dont know im tired...and thats where i shift and i like it... ive gotten a 16.09 so far that way, and thats only with a filter and a catback exhaust...

 

I shift 7000-7500, and I have DX.

 

yup me too
i shift 3500-4000 as a normal driving

 

yeah, 3500 - 4000 on average shifting.
