Mk1 Race Engine Discussion

[Water Boy]

flywheel hp, 8v, twin carb, big valve head, ported and polished, lightened flywheel, fully balanced and blueprinted internals with flat top pistons etc.

How many pony's do u reckon that = to the front wheels... Around 80hp...

not likely mate, nearly 100hp lost through the driveline.... thats fairly inefficient dont you think!!! no prob about 140hp through the treads

140hp at the treads out of Mk1 N/A on Carbs is pretty damn good... Why doesnt Bill race this super engine?

That motor isn't a 1.6(though it's based on the 1.6 block and head) it has one of the rare US spec 1.7L cranks.
Don't mean to question the output, but it's never been tested on the dyno. Bill sure knows his stuff though.
He's also got an F2 8v Camshaft sitting in his garage...........

Hats off to anyone that bothers to throw big $$$ at an 8v

Remember hp is nothing without torque!

[velly_16v_cab]

back home in the uk most people run 2.0 16v in mk1's, the light weight car with a 16v lump pushing out 180-190 bhp (at the flywheel) keeps them up with the best that the riceburners can offer lol
Most of the guys are still running on k-jet and not carbs to keep costs down.

my mate has a 2.1 8v TSR motor in his mk1, its running about 165bhp @fly
its a silly quick car, but has cost him $$$$$$ (well, they should be pounds signs lol)

Tel me more of this 1.7l crank... I seem to have one sitting around my place at the moment - still hiding in it's original block (EN 142xxxx). A present from Uncle Peter. Why is it so rare and what can it do for me??

That sounds a bit better...

The 1.7 is not a rare beast its just was not sold in oz, it was a us spec vw 8V motor which also made its way into the festy dodge OMNI. If you like 8V engines, there are 1.9s from AUDI which are the mostly the same as 1.8s with bigger bores and slugs, and the later vw 8V cross flow heads can also be fitted to 1.8gti engines. Here is a source of some good vw info on engines....

The berg cup motors are all 1600s as they run in that class, the 16V ones you see manage up to 240HP / 10 000rpm and cars come in at below 700kg , these things are really fast! as far as horsepower goes, Bertils in the states have been making superVee engines for open wheelers over there in the US for ages and there 8V 1600 vw engines produce 210 - 215 hp. These are full dry sumped race engines for open wheelers and wouldnt have enough torque to work well in a tin top car To have a F2 vw motor built in Australia would cost between 15 - 18K so its not a cheap horsepower option

Avitar pic shows my itb 8V 1.9 I built recently hoping for a strong 165hp at the flywheel and plenty of grunt

Nice one flog, excellent explaination.
