Just read the Pirate thread.... Hmmm, this guy sure is "different"
OK, so he's running a buggy with a glide - 1.8:1 1st gear, into a 4 speed atlas with 10.5:1 compound low.
With 4.88 gears, I get 92.2: 1st, which + converter will be cool.
I am sure it will be fine in the rocks, but on the street???? - Here's the problem.
so you try to pull away from the lights. you only have a 1.8 first, so you need plenty of stall to make it pull. Let's say 2500 rpm of stall. That's 29 kph of road speed

so there's a lot of slip and bogging anf general misbehaviour to get it of the line.
You accelerate up to 100kph, which is 5200rpm..... and then change into drive, which drops your revs to 2900 rpm... very marginal I think. If revs drop back to 2500 rpm, you'll drop below your stall speed and the car will get sluggish and the converter will cook, so you kickdown, revs go to 4400 and you buzz off towards cruise speed again.
Its just not a solution for a car driven at speed/ on the street. At all.
The fact this guy is setting it up with Swist GTI cams/head and motorbike carbs ? Like I said, cool for a buggy, but not for any more than that.
