HSC stands for High Speed Conversions, they were a perth company in the 70's / 80's who did alot of vw speed work, they had a stage 1, 2 and 3 cam.
The 1 was a mild street cam
The 2 was meant to be a hot street cam
The 3 was a drag cam, and supposedly wouldnt idle on a street motor.
The HSC 1,2 and 3 grinds are still being made in perth (I think it is Southside Engines ? or Camshaft Engineering ? not sure.....) but Veedub Center
in Osborne Park sells them off the shelf, and I had mine ground through Bill & Chris at Volkswest.
Now, as for actual lift and durations............ who knows ? There is a bloke who used to work for HSC who still does VW work for a company in morley
I think, I wrote his name down, but have lost the paper. He would know the specs.
Anyways, to answer your question - depends on the carby. I've only ever driven 1835's with Kadrons with HSC2 cam in them (2 - mine and my brothers).
They give good power from about 2500 rpm on, up to about 5000rpm. I've never worked out if its the carbs or the cam choking my motor.
I originally had a DCNF40 (single, two barrel non progressive) on this motor, and the kadrons are far better.
My gut feel - if your motor is running slightly higher compression and baby dells, webers or kadrons, then yes, stick the HSC2 in it. If its running a
counterweighted crank, you may want to investigate the more well known cams, and utilise your full rev range (my motor can spin to 6000 - 6500, but no
point past 5500).
Anyone else got experience with these cams ?

To bring this thread back to life, and hopefully clear it up for all those of us 'lucky' enough to have a HSC#2 cam;
I've spoken to John at Vee Dub Centre in Osborne Park, and he has the cam specs (but couldnt lay his hands on them just yet). He is going to search
for them and let me know, so when I find out I will post them.
Essentially it is simply a reqground stock cam, pretty mild (he equated it to an Engle 100 or thereabouts).
He mentioned (from memory, so maybe not so accurate) that it had only about 8 thou more lift than standard and approx 5° more duration.
Does anyone know what the standard lift and duration is for the standard cam ?
Will let you know more when I find out.

How would you get more lift out of a reground stock cam??
Guess i dont understand cam regrinding??
Do they weld onto them and then grind it away???
Otherwise if it was just ground it would lift less??? :jesus

remember its all about the ratio from one side to teh other. eg if they frind down the small side by 2mm and leave the lobe at standard height it
means the lobe is 2mm taller than the small side.
that really doesn't make sense. but its all ratios......
I have no sympathy for my car, only the wallet that pays for it!
Go hard or go home!!!!

Advertised Duration for a std cam is 250`with lift of 0.334 thou.Engle and Webcams 1st step up from stock are 26`and 20`more
duration and 40 and 24 thou more lift http://www.tvwdra.org/tips/vw_camshaft_info.htm :kiss |

When you regrind a stock cam for more lift, like BiX said, you are making one side taller than the other relatively speaking. Technically its called
reducing the size of the base circle (if you drew a circle at the lowest point of the cam lobe, that is your base circle).
So if the std cam is 250° and 0.334" lift, then the HSC2 must be about 255° duration and about 0.342" lift. Not a big change.
The guy at Vee Dub Center never got back to me with the precise figures.

PS this means that when you install the new reground cam, at lowest point on the lobe, the pushrods are actually 8 thou further inside the case, this
slack is taken up by extending the adjusters on the rockers by an equivalent amount when you set your tappet clearance.

Hey Doug,do you have a dial gauge no dont laugh im serial,if you did you could wack off your valve cover and measure the valve lift directly and then
compare it with the Web-cam specs for a stock 1600 given at this site http://www.tvwdra.org/tips/vw_camshaft_info.htm goodluck bud :thumb

I have access to a dial gauge actually through work.... I never thought of measuring the lift directly..... no reason I couldnt though, with the right
magnetic base on the gauge I could stick it to the bodywork somewhere as a firm mounting.....
Good idea - I'll have to do that next time I service the engine.
