Hello

I have a 1998 1.0 3 cyl 5 speed. There is no tachometer or shift light. Does anyone know the ideal shift points by speed per gear?

the gear shift points by road speed are listed in the owners manual for the car. ;)

i don't have an owners manual for the mk5 g10 but i recall 3rd being 35 mph, 4th being 45 mph, and 5th being 55 mph.

you can pretty much feel when the engine runs out of wind, usually around 4500 rpm in stock tune, and i just shift when power flattens out, tach or not. :twisted:

bigbad, if your g10 is out of wind at 3500 rpm you need to do a few things. :blackeye:

the only way to make any power from a 1 liter engine is to rev the fuck out of it. :wink:

It's not out of wind. The sound at 4000rpm sounds like a crotch rocket at 10000rpm. I baby my cars though. Try not to rag them out. So I don't have to replace things as often. Now on the other hand. When I get this baby race ready I want to push 5-6000rpm. If not more with a cam. But as a daily I'll keep her under 3500. :wink:

shifting above 4000 rpm is not ragging on a g10. that's how they were meant to be driven.

lugging a g10 is far worse on it than driving it harder. :wink:

driving a slow car fast is a lot more fun than driving a fast car slow. :ez_pimp:

You won't hurt your engine revving it up as long as you aren't running it dry of oil. If it was harmful the redline would be lower. And many engines have their redlines set because the power band runs out, not because you will damage the engine.

For the best fuel economy you can shift between 1800-2000 rpm just fine. I would shift at 10, 20, 30 and 40 km/h and cruise around town in fifth at 50 km/h getting 40-45mpg no problem

Hmmm. Maybe I'll test out this punching it to 4500 rpm. Wonder what gas mileage I will get? Lol! I'm getting around 45-50 now only hitting the 2500-3500 mark. I could only imagine maybe 30-35? It's a 1.0 with like 50hp. It isn't a vette. Or even a gti. I just don't see how reving it up to redline won't wear things out faster as the engine is rotating faster. Like why race cars are most of the time torn down and rebuilt after hard races. Maybe I was just brought up on a different school of thought.

Regardless, 10, 20, 30, 40, 50. Would produce good mileage. While 30 mph in first gear is fun :mrgreen:

Revive a 4 month old post :)

Been through a few of these cars, stock shift points for economy around town on flat roads is at 3K RPM.

The speed your at with that RPM differs depending on tire size and tranny gearing (XFI/Std/Auto).

On my 92 and 94 Metros I had the little "Green Up Arrow" come up on the dash to tell you the best time to shift.

I installed a GlowShift electronic tach and shift light (cheap fun) and fun shifting happens around 5K rpm.

my auto cars.....put it in drive, put the gas to the floor and let the trans do the rest....get to cruising speed, let of the gas to maintain desired speed :-P
5 spd 1.0? usually around 4500-5000 rpm gets the most out of each gear and engine
gti? 8600 comes up very quickly :twisted: ''normal'' around 4500-6000
its all in how the driver feels, and what they are comfortable with....
have run many 1.0 engines bumping off of the rev/fuel cut with no ill effects.

1.0 love to rev around 5k shifting, never drove a turbo but would like to see how quicker it reaches the shift points.

Usually I take my newly bought Metro and install a new exhaust mani, and run full 2" pipe to the back with stock cat, to those stainless removeable core mufflers.

Throw a CAI on it and clean out the EGR ports in head with a metal coat hanger bent up and some carb cleaner.

Makes it run amazing, first gear burnouts easy on 12" tires :P

So I started shifting in the 4500 range. Man with the car gutted it is loud! Murrrr, Muuuurrrrrrr, Murrrrrrrr. Fun shifting! yay! Also did an airbox delete. Which now I can really hear that throttle when it opens up. 65mph in 3rd is also fun. lol
:lol:

I have found that a slightly longer intake CAI pipe helps with that intake air noise and at a certain length "tunes" the intake pulses for a bit more power.
