Hi sj......

There are a couple old threads showing how guys straightened and reinforced their top frames. Here's the first one I found:

Managed to dissemble both frames today and do some mix and match, it appears with some juggling I can piece together a very nice frame with a minimal amount of bending necessary! I will report back as soon as I have access to my Dad's Press again, unfortunately that won't be until next Saturday and of course this week it will be in the high 90's! Breaking out that sunscreen! Cool

Rivets from Killer ordered for Frame mix and match. Canvas has been patched, she aint gorgeous but she'll keep me dry if needed!

It took the Carbs 3 sessions in heated dip to get the varnish out, they should be ready soon.

Ordering the 356 Pulley, Type IV cooler, Shroud, Vinyl Rivets, and Vintage Speed Exhaust soon.


On the 356 pulley, I've seen guys run them with power pulleys on the engine to make up for the smaller diameter. Be advised stock cooling fans do explode when spun too fast so a large diameter pulley and smaller generator/alternator pulley will yield some HIGH fan RPM's. If you really need this mod, look into a welded/balanced unit.

Talk to these guys about the type 4 cooler shroud mod:

Have you determined that you need more cooling on your car? My 2232 with stock cooler/fan/tin runs normal temps.

Thanks Bashr52,

Always appreciate your insights, in answer to your questions...

Yes i've done the math, running 230+ Oil Temps at 58 MPH on the highway sometimes and she is now my daily so gotta get her cooler.

Got a pair of Dual Kadron's just sitting around so... Switching from Center-mount Weber Progressive to dual Kadron 40's, and changing restrictive beetle exhaust with a muffler from vintagespeed, this will improve general flow as I have a Norris 407S Cam in her. This may or may not improve temps, we will see.

Upon looking at my seal and noting the rock hardness as well as gaps at rear corners I decided to replace it, since it's easier to do the seal with the engine dropped I decided to go ahead and do the Type IV cooler as well as the late FI Beetle Tin (for the Venturi). I am in communication with the guys at www.awesomepowdercoat.com (very cool guys btw) and also now have access to some OG Tin and a Gene Berg tack on extension kit if I decide to go that route.

I agree the welded fan is a must if I am going to do a 356 Pulley (http://www.vwispwest.com/jzv/prod?itemId=50931) on the Gen (leaving crank pulley stock FYI) and plan on ordering one when I get the pulley.

As you can see I am attempting to get more air into the Tin without body mods (which largely don't work) and going the same route as our vaunted German engineers did over time.

This is all an attempt to avoid an external oil cooler because I do not have a proper oil return tap on my case and have been told that the cavitation issue of the oil return at the pump (those full flow kits that mount at your oil pump spot) is significant.

If this does not work then I can always still crack the case and, Tap it (refresh things in the process), re-assemble and still benefit from changes above.

I have this crazy idea of adding a Ed Gilmore AC system to my setup after I have my cooling sorted out. I already have the mount and the Gilmore 1/2 HP Compressor from a previous build, all I would need is an under-dash unit and condenser, but that's crazy talk for another time! 8P

That's a crank pulley (albeit a very pretty one). I don't see a 356 gen pulley on that site - I bought mine at Stoddard.

When you do get it, order extra shims. The hub is longer, I think because the Porsche shims are thicker. If you use the standard 10 VW shims, the nut will hit the hub before the shim pack is fully compressed, which makes the pulley wider and narrower as it turns. Ask me how I know ...

Thanks deafen!

That would have been a costly dumb error on my part!

Yes I have heard about the shim issue and will order extra, looks like a very reasonable price for inner and outer together.

Hey deafen,
And everyone else for that matter...

I'm ordering both halves of the 356 pulley, 2 sets of shims and a nut from Stoddard, do I need the 356 Generator Pulley Hub along with it or is that unnecessary?

Hi. I believe you do need the hub as the hub is what sits on the key'd shaft and then the pulley halves index onto the hub with the shims, etc. I don't think I would modify a VW inner pulley half for this. This upper pulley whether its a VW or the 356 spins pretty fast, 1.7 to 2.1 times crank speed. You can get the parts locally from Pelican (Harbor City) or Sierra Madre Collection (Pasadena).
For what it's worth, racin Jason is local to us and was selling welded fans. Looks as if he hasn't been logged on for a few months but has a e-mail link.
Hope this helps, Bill.

Thanks rockerarm, hub ordered.

Update time!

Frame is coming along nicely, going to do some final straightening tonight, got the rivets but am still waiting on Killer's Nuts (insert joke here!). Vinyl is nicely patched and ready to install.

Kadron Carbs restored and re-jetted for my 1776 engine (may require some fine tuning after install, we'll see, that Norris 407s cam can be a bear at idle).

New Engine compartment seal in hand.

Restored and modified stock late model FI Shroud with Venturi Ring and widened doghouse for T4 Oil Cooler (along with adapter and hoover bit) ordered and en route shortly.

Porsche 356 Generator Pulley Halves, Hub, nut and double set of shims ordered and en-route shortly.

So all I am missing to start are the parts on order, a T4 Oil cooler, and the Vintage Speed Exhaust (if they ever return my mechanics calls). Although truth be told I could just use my old empi tri-mill knock-off, it will be loud as shit but at least it won't restrict like the pee-shooter exhaust.

Side question... When folded down am I correct in assuming the rails should line up (so the edge protectors if I ever get any slide on easily)? My top ones are bowed in a bit...

I would like to make sure im not breaking something before I attempt to correct it tonight.

Thanks all!

They look good to me. I always have to just give the covers a little push. Coming along nice.

Thanks germanbilly,

Did a test fit this evening after yesterdays bend-fest, was still having issues on passenger side and windshield / side curtain geometry. The Soft Top Frame was still forcing the windshield forward a small amount, just enough to cause a gap at the top of the side curtain on both sides which would easily allow rain water in.

I switched the rear portion of the frame out so now i'm back to purchased bow and rear with mix matched arms and supports from my mechanics donated frame. Windshield and Side curtains now align properly and there are no gaps along top of side curtains on either side accept for the passenger rear angled part, easily corrected with some weather stripping. All in all i'm very satisfied. I plan on putting on the vinyl this week (heat permitting and Killer's Nuts still pending arrival) and finally installing. I have Vinyl treatment/cleaner as well as window cleaner, looking forward to a waterproofed, clear windowed soft top!

Does anyone have instructions or a diagram of the boot for the soft top when folded down? Was gonna continue the do-it-yurself theme and attempt (with the help of my roommates fiance) to make my own Soft Top Boot!

The fun continues... 8P

FYI, if you can deal with a little more road grime/dirt in the engine compartment, there are 2 free mods you can do to increase air to the compartment. One is to remove the FRONT (not rear breast plate) tin entirely. There is a lot of free air under the car you can grab this way, but the dirt/grime entering the car increases greatly). The other is along the same lines. There should be a stamping on that same tin, opposite the cutout for the oil cooler exhaust.

Image may have been reduced in size. Click image to view fullscreen.


You can cut this stamping out which leaves a path almost directly in front of the fan for more air from under the car to enter the compartment.

I've seen conflicting results on the type 4 cooler mod. For the cost of the cooler, and a modified/modifying the shroud to fit, I haven't been 100% convinced its worth it. 2 more rows of cooling surface sounds good, but I'm not sure it works that way in practice.

Thanks Bashr52,

Ya I have considered the cut out option (too much off-road debris for no front tin), I have also considered adding some sort of filter over the cut out opening, just trying to figure out how to ensure it doesn't get sucked into the fan.

The cooling benefits will be further muddied by a change in carburation and exhaust. But here's to hoping!
