What power?
OK guys, IDEAS Please
This is the rear compartment for my Formula Ford, It is designed to take a X-Flow and Hewland gearbox but I really dont want to spend well over
£1000-£2000 on a second hand Hewland gearbox.
Any ideas what other power/trans will fit (for the purpose of this please ignore bike power as that is a whole other topic )
I know measurements would be good but the car is about 250 mile away from me at he moment so suggestions welcome.
Cheers
Mark

You could fit an audi like the yellow mk gtr demonstrator.

assuming you want to leave the chassis as is you're limited to transaxle gearbox and inline engine as i see it, so vw/audi and renault units are
the comonly available ones, whether they fit or not is another question I can't help with I'm afraid, though i would be interested to hear
the outcome as there is a ff1600 without a gearbox or engine sitting in pieces at a friends house....

I know the car is setup for a beetle diff at the moment so any VW expects that can tell me what trans will mate up.
Ned... get that FF mate, if the worst comes to worse you can always go bike power.

lack of garage space is the problem, buts its sitting in a barn that i know where the key to is at the moment, so maybe eventually. we shall see. my
preference (though i know you said bike engines are another thread) would be a cbr1000 or other goodcheap bike engine inline, coupled to a sierra dif
with a double u/j something like spunky did in his car.

you can use a beetle transmission. A lot of people in autograss (where I race) use them, with modified internals. The cost depends on how many gears
you need. Most of the grassers use hewland gears inside the beetle casing.
The other option is the audi box, again used by a lot of grassers so there are adaptor plates available.

The original Hewland transaxles were modified VW ones. heres a link to the history of Hewland transaxles:

This page may be of some use to. The drawings and pictures might be useful. http://www.hewland.com/svga/homeIE.htm

yeah , early hewlands were VW with magnesium casings .
you can turn the diff round to make the mid engined , and theres plenty of adapter plates , but youll be stuck to about 130-140 hp before mods are
needed like diff side plates which break .
the transporter ones were able to take more power and are 5 spd , beetles are just 4 speed .
then theres ratios and diffs which might not be suitable so , maybe look at a better option in the first place , depending on what application your
building it for , My mates next door to me have , beetle boxes lying about ! , i believe theyve also got a couple of transporter boxes .
ive got a renault box and its pretty heavy .
try a secondhand staffs box , they might be a bit more cheaper than a hewland .

Cheers Volvo
I am mainly looking to use it on track days so I would think 140 BHP should be more than enough when the car is going to weigh about 350kg.
If you know of any transporter boxes that I could get to Lancashire (I cant drive at the moment due to detached bicep)then please let me know

Friend of mine's sports 2000 race car has a beetle cased mk9 hewland box, he used to run a vauxhall xe with it and it would occassionally break
2nds and thirds and he had to be careful with it off the line, he ended up 'lifing' 2nd's and changing them quite regularly. I
understand that FVL used upgraded mk9 gears in their own casing, not sure of the details, but they must have put down reasonable power.

Hi
Do you know who manufactured the chassis?
looks dead simple to make.
Could be just what i'm looking for for my next hill climb car.
