I'm actually removing a type 2 reduction transaxle from the car.
It had a 4.37 ring and pinion plus 1.26 reduction boxes.
It has lots of torque with the stock 1600cc.
I've been eyeballing the 4.86:1 ring and pinion for my IRS trans.

I had a tri-mil when I had the bug but I was planning on bumping up to the Vintagespeed 1-1/2" one that tucks up like the stock one. Have you thought about going that route?
Also I'll trade you your reduction boxes for a HD bug transmission

If you weren't so far away!
It's a good setup, has the latest model John Johnson no hop kit.
1963 &1/2 year model (odd ball- small nut, but 1 ton rated)

Alright so here is what I have planned to use.
The car is not and will not be a daily driver, probably will see less than 3k miles a year, I only average 9500ish miles in my daily driver.
it's just something for recreational entertainment and occasionally drive to town.
Scat Volksaver 69mm crank.
5.4" I beams, Idk what brand.
Scat C-25 cam kit.
Scat 1.1 street duty rocker assemblies.
Melling oil pump. (Or some other 26mm pump, I can only find 30mm melling)
Stock flywheel, modified for 8 dowell.
A A 88mm thick tops.(already have)
stock dp heads.
pertronix SVDA, pertronix coil, wires.
single 40 IDF from AC.net w/ setup option.
This exhaust, header is in related parts, 1 & 3/8" :
http://vwparts.aircooled.net/Hide-Out-Muffler-Hideaway-for-2031-10-13-2032-p/2556-2556-13.htm
This will be my first build using performance parts in an ACVW so if I picked something out that's junk then a decent part suggestion is appreciated.

| Not sure you need the I beams? Stock VW rods will do and the money saved could go to balancing and maybe a heavy steel front pulley - if you want low end grunt. |

the weight of the flywheel and/or pulley has nothing to do with how much torque the engine has, at any RPMs.

It only changes the conservation of momentum. If you get a heavy pulley, have it balanced with your flywheel else you're just moving backwards.

True but, like the fullweight flywheel, the additional mass will help keep those heavy tyres turning that bit easier and feel like more torque. Obviously all has to be balanced. |

I have a 1679 with FK-41 on 112 LC, 1.4 rockers, 9.5 compression, stock heads with zero port work, dual 36 DRLA's. Have it in my '64 (4.37 trans) and the low end torque and throttle response makes it almost hard to drive smoothly around town. Makes 90-92 flywheel hp and runs 9.90 in the 1/8th mile. It has a full weight flywheel, counterweighted crank, and a 5 pound pulley. The rotating assembly is something like 44 pounds, it's pretty heavy.
This was when Raby had it with a single 40 DRLA.
In my '64 with dual 36's.

I found a competitively priced crank to possibly use.
http://www.cbperformance.com/ProductDetails.asp?ProductCode=1105
the description is a little vague, Idk if it is counterweighted or not?
Would it be necessary to use something like the 1110 Rev master crank in my engine build?
If not necessary, would it be more beneficial if I chose such a crank?
if I use the stock rods then I will put the money towards the crank & dynamic balancing.
Also how much valve lift is use able with stock sized valves?
Reason for asking is like the w-100, web 119 & similar cams have around .420 lift and the fk41 has like .455 lift.
Other name brands use lesser lift, like the scat c25 has .365 w/ 1.1's
advertised duration is close the same, web 218 shows 280° and scat c25 shows 272°
Using a smaller cylinder and single carb, I figure there is a use able lift threshold, may be wrong though.

That crank is counter weighted. Compare it to a picture of a stock crank to understand what counter weighting is.
I personally choose to use DPR cranks. Quality German cores, quality machines in the US.

Here's my 1679cc for comparison.....
Looks like I hit 85 plus mph before I let off.

Not sure how much torque it has but My Iphone dyno showed 179 crank hp.
It did 109 mph in the quarter.
At a standing start it has slight traction issues.......

It works off the Iphone. You put it in a holder in the car and it measures speed, distance and g-force and comes up with an elapsed time and top speed.

I have it set to give me Crank HP.
You input your cars weight with you in it ready to do the run and it puts out this info.
My last run with the older turbo and 5 lbs. less boost gave me 138 Crank HP.
Here is the Video to go with the Dyno info.

Get a DPR crank. High quality, low cost. Also, there is no need for I beam rods. Stock and properly rebuilt/balanced rods are more than up to the task for your 1679. With a counter weighted crank, I see no reason to not lighten the flywheel. You want to invest your money in the heads- that's where power is made. Stock size valves are fine for this build, get a proper valve job, blend the seats into the ports, match port the intakes, and unshroud the valves. Good HD single springs, solid shafts. Set the deck tight, no less than .040" though. Engle 100 (or Web Cam 119?), around 8:1 CR.

How about a Web 119 with 105° lobe seperation?
