6 speed Impreza's - in 6th gear whats you mph?
 
I want to know what speeds other Scoobs pref (bugs) are producing to see if mine is the same? mine in 6th gear at 2250rpm does 50mph & at 3250rpm 70mph - are these similar to yours?:wonder:

C. J. 06 December 2010 12:56 PM

Yes
I'd say you have the same as me a JDM 6 speed box

dunx 06 December 2010 12:57 PM

3 krpm @ 80 mph or...
27 mph per thousand rpm, hawkeye six speed.

P.S. Your's a JDM ?

Timur 008 06 December 2010 01:19 PM

cheers:thumb: yep mine is a JDM

I get 2500 @ 60 mph in 6th, on a JDM blob with facelift, with 500rpm/10mph increments after that (3000@70mph, etc).

I did notice that the pre-facelife blob eye 6 speed box was very slightly shorter; when I had one for a week on loan; which could be the same as the ones on bugeyes.

The ratios for the JDM 6 speed box have not changed since they first introduced it in the bugeye AFAIK, the slightly shorter gearing might be due to a difference in tyre size.:)

That's probably why, mine has 17" BBS, MY04 had PFF7 18" wheels.

Timur 008 06 December 2010 03:46 PM

i have 18's on mine.. does bhp effect the different amount of revs doing & speeds achieved? or is this all gears & wheels only? also does new/old clutches effect speed too?:wonder:

alcazar 06 December 2010 03:52 PM

No and no, although more BHP might give you a higher top speed. The gear ratio decides on how fast the car will go at certain engine revs.

Think of it like a bike gears: you can only pedal so fast. In a high gear the bike will go fast, (high mph/1000rpm). The stronger you are, (higher bhp) the faster you can pedal.

3000rpm = 80mph forester sti gearing in a classic :)

Timur 008 06 December 2010 04:05 PM

thanks alcazar:luxhello: nicely explained for me:thumb:

alcazar 06 December 2010 04:15 PM

dunx 06 December 2010 08:13 PM

LOL
