why dont you find outwhat the heads flow & run a simulation with about 10 different cams with the rest of your combo to find out what works best for your stuff&cr.so i take it the coffie is good.  |

| Thought a Engle 120 with 1.25's had a .496 lift total, which is rather decent and been proven to last valve train wise with out doing lifter bores... I have been looking into this combo for my 2110 when I rebuild it and do my head upgrade.... RB |

I have a great idea- why don't you decide WHERE you want the powerband to be, and then make your decisions from that?
W120 +1.25's - the dur @ 0.050" will be 256-258' and should provide a powerband peak somewhere around 62-6400 rpm. In a motor that size (over 2 liters) torque will be in the big to huge range. With that much valve lift you'd probably be better off with 1.4's, so the FK8 or FK44 would give similar rpm range with the 44 having the best all around power of the 3.
The FK45 will rev another couple hundred rpm with the typical FK40 series big fat lower torque curve.
The W125 with 1.25 rockers will have a dur @ 0.050" of 266-268', which will enable the motor to rev to 6800? almost 7000? rpm with power and still have great low end characteristics. The FK10/1.4 has similar specs, so I would expect very similar performance with perhaps it being a little easier on the valve train. Not to be left out, the FK46 fits in here as well, and with the same duration (268' @ 0.050") and .030" more valve lift (and faster ramps) than even the FK10. A local guy with an FK46 equipped 2332 (and close 3rd and 4th gears) has run high 11's and drives it regularly on the street from spring to fall.
Downside of any of the W100 series cams with 1.25's is perhaps a little more valve train and lifter bore wear and not quite enough lift to take full advantage of the flow capabilities of the heads. The FK8 and FK10 give a little more valve lift (a little more all around power) and are easier on the lifter bores, the valve lift coming from the rockers instead of the cam/lifter. The FK40's cams are the big winners for power with the fastest ramps and most lift, the downside being lifter bore wear is a real possibility if they're not sleeved.

will enable the valve train from the lifters on up to be oiled 100% of the time, which will translate into lower operating temps and longer life.
5lug- Pick one already!

What he said! ^^^^^
I went FK-8 for all around manners as a daily driver.
Maybe on the next rebuild it will get bumped.
But for now it stays what I have as I have only really ever driven a VW with a 1600.

Lol! That's where I want the power.....6200-6500 rpm limit is plenty....and a huge torque monster is what I want.......W120 with 1.25's or w125 or the FK44......I'll talk to Roy about it and see ..

If you go back to page 11 you will see my build list again. I asked all the experts on here and made a decision and went with the w120/1.25's .
From what I understand the W120 is a no brainer for an excellent powerful you cant go wrong cam. There may be better there may be worse but the 120 has a long successful history.

Yep.....W120 with 1.25's then......I liked it in my small 1835 so I'll probably love it in my 2176.

| get the drd r-96 or the slr xr296 the duration is a little lesser than the fk8 and a little over tha 120 but the intake closing is the same as fk8. |

257*@.050"
Close to an FK-8 on duration, almost exactly the same on valve lift, just a touch shorter. Works well in my type2 truck, I like the power band and how it comes on at 3500rpm. It's smooth yet decisive.

Art Thraen.....if you're out there, the carbs are on their way
Roy....heads with intakes and motor parts are on their way.

You should try to attend and meet the local VW Mafia..... |
Heck yeah! I'll be there.....!
