Hi im looking for a cam for my 1600, i want something diffrent then a engle 100/110 everybody runs.
Although engle vz14 sounds nice!
Looked at some cb cams 2234/2237/2240/2241/(or any other)

I want torque!!

Specs:
full weight 65 beetle, stock gearing, 225-50-15 rears

85,5x69
stock mild home ported heads
dual weber 36idf's
super stock rockers
light flywheel
hd single springs
rev limit 5000/5500
what cb cam do you guys recomend and whats their powerband.

With just 1600cc to play with you must be very careful in your cam selection. It's very difficult to just install a cam and get more torque. Your engine combo sounds decent, hope you are running a good 1 3/8" header. Of the Engle cams you listed the only one that would give you more power without losing too much bottom end torque would be the W100. The VZ series is a bad choice for your engine and the W110 is too much cam, you wouldn't like the loss of torque.

Of the CB cams the 2234 would be about the same as the W100. 2237, 2240 and 2241 would be too much IMO.

I recommend the Cheater cam (and a set of CB's lightweight 28mm racing lifters), 2280. It would match well to your combo, has power to 5500 if you ported your heads well - that is if you didn't just hog the ports out but just lightly massaged them so port velocity doesn't just drop off. http://www.cbperformance.com/catalog.asp?ProductID=1244 Click on Cheater Cam and read what CB says about it.

Don't fall into the "bigger is better" trap. With just 1600cc you are very limited in cam choices that will help the engine with torque. Since you have to split the case to add a cam anyway.....hint: a 74mm crank - even with a stock cam - would make way more sense than a bigger cam in a 1600. Then again, with a 74mm crank and 1699cc you just opened up a whole bunch more possibilities in cam selection.

Why wont i like the w110 and vz14?
I see them in similair builds here.

And is the 2237 the cb version of the vz14?
These cams seem to be perfect for torque.

I have e-mailed pat dows last week but havent had any response.

I use the 2280 in all my stock rebuilds, runs great every time, whether it has stock intake and exhaust or bigger

The 110 will give up low end power in favor of higher end power. You said you wanted torque so that one is out. Some people do it but they are giving up low end grunt to gain mid and top end power.

The VZ series are fast ramp cams and are rough on the valve train. You should have sleeved lifter bores to run that one and probably have to pull it down for new valve guides and a valve job twice as often as usual (maybe more). VZ was intended for racing. Racing engines get rebuild after every couple of races if not more often.

Darth gave sound advice. The cheater cam sounds like a good option for you.

Web 163 on a 105LC is another good option for you.

Just depends what you mean by torque exactly

cams 230-240 duration at .050 may give you MORE torque, but it will be located 3500 rpm and up, you WILL lose some low end, if you want to have solid pulling torque clear down to idle the cb cheater is what you want

Yeah the web sounds nice.
i tried to order from webcam trough my supplier twice.
3 months later still nothing. :cry:

So i want something thats available here in holland.
options are cb,engle and scat.
and i dont want a scat because of the lifter horror storys.
I like the cb's because of the nice lifters

I read that the wear with the smaller vz14 aint that bad with good oiling
and 30mm lifters?
i have got a 26mm schadeck full flow and the complete HVX mods.

Consider the web 218 or fk-41 rather than the VZ-14
CB's cams and the VZ cams are just simply more "crude" grinds, more noisy but not necessarily better performance

Several folks here have used the fk-41 in smaller cc engines, some with ratio rockers and some without, seems to perform very nice

CB's lifters should work well with engle cams too

Like i said webcams arent a option over here.
And i allready got stock rockers. And a fk41 with stock rockers is even smaller then a w100.
Do i want Torque down low or midrange? Dont know yet, but like to know my options.

And the reason i asked for cb is also because they have cams between a w100/110.
Isnt that a good option?

I got Web and CB cams on the shelf. But if you want good lower end torque I´m not sure the 163 is the ticket for you.
I would lean towards CB 2239. That´s a W100ish cam, but with more upper end to it.
Well done not too large port stock heads, the 2239 cam and you are on 90 hp easy at about 5300. Redline 5700ish. Max torque is usually in the 3300 area. 140 to 150 NM depending on the rest of the set up.
If you want superior lower end torque and dont care for power above 5000 rpm. get the CB 2280.
I stock the 2280/34 and 39.

The 39 sounds perfect!
Think im gonna order that one.

I like and use the Scat C25 cam for great torque down low, and it's easy on the valve train.
