Do you have any updated fuel economy numbers with the new 6th?Who is doing your installation?
Do you have good fuel consumption numbers for before the change over? That will be interesting to see.
But the transmission now feels really great in every day use for me. The old gap I had with my .622 5th gear is gone. The .71 5th and the .588 6th just fit like a dream, I shift as low as 2000 rpm in each gear and the engine drops to 1500 rpm in the next gear. Just like clockwork. Use a higher shift point and each gear change drops down to the same rpm. Wonderful spacing.
The true 75 mph at 2000 rpm is also great.
Sorry to say no new numbers yet. Have not filled the tank since the conversion. Looks as if I may not get home till mid July.Do you have any updated fuel economy numbers with the new 6th?
Mike,
How long did it take your shop to do the swap?
Mike,
What size is your engine? 1400 cc?? Do you know what the car weighs? 550 rpm drop at 60 mph is huge - a 25% drop at the same speed. You should see some fuel savings indeed.
I will be interested to hear if you can use your cruise control in 6th gear after the conversion.I am. I have a clutch coming up so I am going to do it at the same time. I have tracked fuel consumption and mpg for the past 120k miles, so I have good data to compare the new gear.
I just finished timing belt, water pump, egr & cooler delete, intake cleaning, and stage 1.5 Malone tune. I was hoping to do clutch and gearbox at the same time, but no joy.
Me too.I will be interested to hear if you can use your cruise control in 6th gear after the conversion.
Does it resemble a power tool? No? Then that's whyHas anyone considered a chain cutter instead of the angle grinder to cut the shift bar? No sparks, no dust, just two quick snips?
Yes, it is also possible without sparks but you have to have a very big chain cutter, we have good experience with the size 36", length of the holder is 28 inch. When cutting, the one handle is leaned against earth, and you can then operate the other – if necessary – with the entire mass of your body. During this operation, it is necessary to make sure/check that the shift rail is not leaned against the gears and it cannot damage them while cutting, when the force developed has to be relatively high.Has anyone considered a chain cutter instead of the angle grinder to cut the shift bar?

The nice thing is that you have a long history of fuel consumption on your fuelly. give it a few tankfuls and it will really start to show (with the same driving) the difference that the additional gear makes.First full tank after the 0.588 6th gearbox upgrade - 86.4(!!) mpg imperial, was averaging 77.1 mpg imperial (a 12% improvement). That's more than I had predicted, but it has to be noted that it's not a representative tank due to the 100 mile trip back from Stealth.

Axial float = also called end-float.Radim said:... Important is axial play on gear wheels 5 and 6. The first thing you need to check ... is play in axial direction. It must be 0.2-0.3 mm. ...
