Most important question - whats your budget?

I'm curious why you would use V4 given you still have to find one?

There a lots of modern V6's out there that will be cheaper and better.

As far as transaxles go a second hand Albins for Pro Lite would be a good starting point. They are usually offered for sale at the end of the season.

I was sort of hoping the first response may have been yes I have one I don't need anymore. you never know I spose

reason why
nice and short for the mid mount scenario
light
good hp
and plenty of torque
And an engine builder who builds v8s for speedway
we won't mention ofcourse availability of some parts or lack of.
and also down on cubes a bit as well.

getting a good 2nd hand albins is certainly an option but ratios weight and length will be an issue and the inch or two of suspension travel I lose

Kick your dog
did you change the c&p to 4.00 to get 1st low enough?
do they put strengthening plates in them
how much does your buggy weigh
how big are your rear tyres
did explore that option a little but it started to get well up in price and not as appealing as say a mendeola md5 or a weddle 5speed if ever they release it.
getting a bit hard to find now unraced at a reasonable price.
so no problems with it that's good

crikey that sounds like a tall 1st gear.
Standard clutch?
certainly a nice weight though
does it pull the 33s ok.
I am considered running a 235/85/16 which is a 32/9.5/16
if I thought it would pull them I would run a33/10.5/16 or 34/10.5/16 or on a 15" rim even better
I think there is a 9" version available as well.
I was concerned that the 1650 would struggle with 33 or 34 tyres
I had a g50 straight out of a written off Porsche for years in the shed but sold it a while back.( before I decided to build a new buggy of course) because it just was not going to fit in the rivmasta .

if I stay with 1650 I am thinking mendeola md5 I like the hv1 but 5 gears would be nice.
having said that to get the ratios I want I need a 5.86 c&p so the pinion is probably no bigger than your g50 pinion anyway.
it appears I may have to much choice.

from the picture I gather that was the lothringer Bob Mowbray had. They are nice buggies. That said I like the buggy I have in the shed now.

I think there is a question or two amongst that jumble
Thanks

don't forget about the weddle boxes. hv1 and soon hv2.

I recently just prucahsed a new hv1 and you can get them for under 15.
people are running them behind v6 turbo with great success .
I will be running mine behind Nissan v6 non turbo for a prolite car

i was waiting late 2011,,i was told to hold off the hv2 was about to be released,,, i would be still breaking the reno if i had waited,,i had my hv1 serviced and it had no signs of the v6 turbo hurting it(which i was extremely happy about)

The 5speed weddle (hv2) is pretty well on the back burner. It has been coming every year for the last 3 years. Weddle is not putting an eta on it anymore. Of course I would love to be wrong. Given their relationship with Mendeola now i suppose the MD5 does the job and I can understand that.
The comment regarding losing to many revs with a 4speed between gears is spot on. I have played with the gear ratio calculator till the cows come home don't seem to be able to get 4 gears to. I am probably leaning towards class2 so the MD5 is about it. I realise the g50 is also an option but I would prefer something new and I think it would be more saleable down the track if ( it doesn't rain soon , kids go to uni, wife shoots thru ) or all three. The way the budget is getting blown to pieces the last one might come sooner rather than later( oh well be a shame to see her go I do like her lasagne). Any way I sort off concluded the md5 the other day and sent of an email regarding the md5 and how to get it out here etc . Out of luck non available till atleast October so I have a bit more time to contemplate ( I did think that was pretty funny)
So I am still open to suggestion till October anyway

I have got a pbs 5speed sequential behind a honda 3.5 vtec. Costs under $15k, 10" randp, heaps of ratios and diffs available, uses weddle internals. No problems thus far, many will knock them coz they dont know them but it is serving me well. If you want further info call me on0439718992..
