Good shifting RPM...

Question:

The 1991 318i i've got, i'm curious to what RPM I should shift at for casual driving. I don't want to push the car to hard and I don't want to lug the engine. Any suggestions?

2500 - 3000rpm is generally the shift point for regular driving....depending on ur definition of regular driving though

Hell I have an 84 318 and offen shift at 4500 out of first to get a good start on the lug I have in second.
I took my lil bro for a ride and nailed the red line line in first and he was like wow and second came along and he was no longer impressed.

between 2000-3500 should be good
good fuel consumption

Hmm, thanks for the suggestions. I try to shift at or below 4,000 RPM in the first 2 gears, and then at lower RPMS as i'm accelerating to faster speeds.

Man 318s are fun to drive have a great sound at rev but the quickness is just not there. I drive a 5sp '84 318i and could not imagine the horror of driving it as an auto.

Anyway I usually shift at 3-4k.

4k is good one for my car seems to be where most of the power is located.

I consider 2nd gear to be the best gear on the car because well it goes to 60pmh of course at redline.

I switched one of my fuel pump fuses out for the 15 rated fuse that was there when I bought the car. It really helped with acceleration, but at the cost of fuel consumption. I would consider going higher than 15 though.

Do you really think that a fuse can alter the performance of the fuel pump? My dad who's an electrical engineer thinks otherwise, and so do I ...

well that's your opinion and this is mine. As far as I can feel the switch fuses has helped. Sure it does not turn a 4piston to a 6piston but I can feel a difference.

For instance, when I was using the fuse specified by the repair manual I had to shift to 2nd at redline half way through a 5 lane intersection. That is no longer necessary now I can go 3/4 to 1/1 way through a 5 lane intersection before I need 2nd gear. Furthermore, my 2nd gear can now go to 60pmh before it would reach 40-50mph and I had to shift.

If you don't believe that a switch of fuses will help then that fine with me but I say everything is worth a try switch your fuses out and feel the difference if you can honestly say you feel no difference then maybe my cars setup is differs from your yours.

Either way this is my opinion and that is yours. This is my story and I'm sticking to it . Have a nice day good sir.

i dont usually agree with jordan's posting ethicsa but i gotta side with him on this one

if you know the purpose of a fuse then you'd know there's no way it can make a difference. a fuse in no way limits the current through a circuit, its simply there to fail in case too much comes through so that it doesnt short out or damage the system in mroe vital parts

maybe your fuse was blown before you changed it

Call me or my comment stupid but that's your blief and this is mine IT HELPED. True that fuse may have been blown, but I do not believe that.

The only proof I have is a change in acceleration. True this change could be in my head similar to people that switch from stock intake to aftermarket but I feel as though it helped and that's all that matters.

Have any of you done a switch of fuses? You know you guys have hurt my feelings , it may be time for a trip up North to correct this .

Oh yeah I would not consider going higher than 15 rating.
