Engine

[louisb]

So after many questions posted here and through a bunch of PMs I have finally finished buying all the major parts for my engine. I still need a few odds and ends but this is what I ended up with:

New Mag Case
84 CB crank w/ Chevy journals
94 B pistons w/ Grant rings
5.5 CB H beams
12 lbs CB flywheel
Berg Equalizer Pulley
FK-45 cam
Denham 44 x 37 heads
Skat-Trak manifolds
48 IDAs
Vertex Mag
A-1 1 3/4 Low Down Exhaust
Berg 3.5 sump

I still need to have the 48s & Mag gone through and the case machine work done.

I wanted to thank everyone here who gave input on this combo. I got a lot of good input and advice from the folks here on the lounge. This is definitely the best VW forum out there. Now I just need to decide if I am going to assemble it myself or send it to someone else to build it for me.

Have a happy holidays!

Thanks,

Nice combo Louisb andkeep us posted on the build and happy holidays too buddy.

tip#1. It goes in the back of the car

[GreenTom]

hmm
84mm cheepo non nitride crank? weak chevy jurnals? with typ1 center main? hmm I would be too scaered to use that...
but maybe I'm wrong...

good luck and all best with the project.
 cheers.

[louisb]

Actually the CB cranks are nitrided and a lot of people have gotten good use out of them. It may not be the best but it will work for what I need it for.

Thanks,

--louis

[nicolas]

is it done yet 

[GreenTom]

CB makes 2 kinds of those 84mm cranks nitride and non nitride... If you have nitride well done. if not... too bad.
I hope everything will be all right

[louisb]

is it done yet 

lol, no.

It looks like I am going to go with Art Thraen @ ACE for the assembly & tuning. Spoke with him yesterday and got a quote to build it and tune it on his dyno. He will rebuild my IDAs as well. Now I just need to get the money together so I can send it to him.

Sounds like a nice solid street monster Louis. Big lungs, shortish rods, and conservative duration/high lift. Hope you're building a strong transaxle.

It will be interesting to compare it to your motor when it had the FK-45. This same basic motor made 204 hp in the engine shoot out. (Though James2 used CNC heads and 5.325 rods) But what was really impressive to me was the HP at 3000 in that test. I forgot the number but it was the highest of any of the engines even though he didn't make as much power on the top end. I think this will be a good fast street engine as opposed to a slow race engine as you tend to say. Tranny will be a berg 5. Now if you will excuse me, I need to go put a kidney on eBay.

Only thing with the FK45... it had a big hole in the midrange, and then took off. Was good to 62-6500. The Pauter cam now is just silky smooth from lower mid range to 7K...no sags. The FK45 was a strange cam to me.

[louisb]

Bill S. recommended the FK-46 for this engine and I may try it out if I am not happy with the FK-45. What are the specs on that pauter cam?

Thanks,

--louis

[Jim Ratto]

272 @ .050"/304 advertised/.406" @ lobe if I can remember.

[louisb]

Maybe this one from Pauter:
R8   304º   274º   0.421"   10.67   108º

It looks real close to the FK-46 or 47

FK-46   301º   268º   0.408"   10.36   108º   New cam
FK-47   308º   276º   0.419"   10.64   108º   New cam

edit: I went ahead and picked up an FK-46 cam and will try it out. Good thing cams are cheap.

[Donny B.]

Good thing cams are cheap.

Yeah, but they are a pain to switch if you don't like it.

True, which is why I am trying to get as much input as I can on it.

[javabug]

Cam swapping isn't too bad, Hot VWs or Trends did a tech article years ago on cam install through the oil pump bore.  They used to do an April Fools issue, but I don't think that had anything to do with it.

I remember that article. I liked the Elephant tach better though.

Oh yeah, you're gonna need one of those, too.

My grind is the R6E8

[bilboa2]

ok, just dynoed my 88x94 2442 fk46.9.6 comp. 5.6 rod,clyde 44x37.5,1 5/8, AT 4300 alt..Guessed at jetting, first pull, 162.2 hp w/ belt and muff.NO 12% ORANGE COUNTY F'N FACTOR ,(WHY DO THEY DO THAT?). Approx hp loss 3% per 1 k ft of elevation,you do the math..was a 2332 k10, made 150 range..(189 at berg ,w/o belt sea level).With berg 1,54 rockers lift increased to 6.30ish w/ fk46. did lifter bores etc. Feel there is more tuning to come.. 1/34, stepped exh, vent increase etc,. Going back saturday to play with jetting, exh.etc, ok maybe shoot a couple of ducks too. mmm, good..bill

[bilboa2]

didn't mean to jack your thread, but my fk 46 measured 271 dur..looks good, "they" say bush your lifter bores on fk. series. oh yeah ,ratto ,I stayed on 108 lobe centers..If i go bigger exh and venturi size, i am sure it will raise my rpm peak hp. Not my goal,Would like it all over at 6500 , easier on valve springs etc.NEXT tear down WILL get bee hives and bigger intakes..thanks.

I put an FK-45 in my buddie's 2110 a few years ago. 82 X 90.5.
K-roc prepped Oval port CB heads, K-roc recomended using really high compression (so I thought) . 10.5/1 (maybe it was 10.2/1. Anyways, it made 168hp to the rear wheels on a chassis dyno. Ran 12.80's in a mostly full weight 70 beetle.
There was no hole in the powerband anywhere. Stab it a 2K and she would just steady increase Tq. all the way up to 7,000rpm.
I think the compression ratio really made the cam work well for this motor.
It never ran hot at all. He took it on many long hour highway trips in the middle of summer (90+F) I would never have belived it unless I built it myself and watched it run.
As a matter of fact; it ran significantly cooler than the same motor with an Webcam 86-C.

High compression combos don't have to run hotter, but they do like the high octane....

The FK-4X series cams are faster ramp cams (espeically with the FK-45). AKA: "rampy" cam. To make it all work, you must have the valve spings "up to the task". 

I think you will be real happy with either the FK-45 or FK-46 with your combo. They are great cams, build and tune it right, and you'll impress more than a few people with it....

CB makes 2 kinds of those 84mm cranks nitride and non nitride... If you have nitride well done. if not... too bad.
I hope everything will be all right

Not sure were you got this info Our 78mm through 86mm cranks are all 4340 chromoly and nitrided. The 69mm, 74mm and 76mm cranks are 4140 chromoly and are not nitrided.

[Ohio Tom (DdK)]

Just an FYI about Nitrided cranks.
Nidtriding is a surface hardening treatment. It makes the outer "wear" surfaces extreemly hard.

This is good for minimizing journal damage during rod bearing failures, In many cases the crank will survive w/o having to be re-ground undersize. (if you catch it fast enough).
Nitriding has little affect on the overall strength of the crankshaft.

I run the non-nitrided 4140 crank in my backup race motor.... It has about 40 passes on it so far and turns 8,250rpm on every shift.
Plenty strong.

[WCB Hitler's Hot Rod]

That's alot of HP for that engine. Who's dyno did you use? What's the CR? Shubee

[louisb]

Those are some pretty nice numbers Shubee. Should be a wild ride.

[Shubee2 (DSK)]

Jm Clarks Engine Dynamics Dyno, Compression Ratio is 13 to 1
