Case:

How about cast-in steel inserts for the main saddles with some sort of step to eliminate movement of the case halves?

How about more meat in the case halves where the main bolts go through so you can crank down the mains without point loading the case?

How about better oiling for the lifters especially on the passenger side? In order for the pass side to get oil it must pass by the cam in pretty small passages. To get oil to the exhaust lifters, the oil must first circumduct the intake lifters. Therefore the pass side exhaust lifters get the least.

How about a cast-in oil thermostat rather than a relief?

How about thicker by #3? No brainer.

How about gussets from the case to the top mount bolts for the off road guys?

How about a bigger bypass hole for those cold mornings? Real easy.

Heads:

How about angle flows with (more than) stock fins?

How about raising the PR tube holes a few mm?

How about more meat around the springs and guides?

I looked hi and low but could not find the EDIS VR sensor setup I saw that was behind the T1 pulley, as I recall the location of the VR sensor: was located on the passenger side of the engine between 90 or 120 degrees from TDC it was a single bolt mount sensor that looked like the one at the URL below-

However a flat platform in the general aria to the right of the outer edge of the pulley that could be taped to fit the more common two bolt type VR sensor would probably be better?

Out of the box:
1 piece block air cooled V-4 configuration
Billet main caps
Chevy main bearing saddles
Chevy cam bearing saddles
Belt drive cam (cam mounted over crank)
Lifter bore set up for Chevy lifter diameter
Keep it a push rod engine
Short and deep cast aluminum oil pan (gives the option of wet or dry sump this way)

Within the box:
Thru bolt case.
4” bore acceptable.
Type 4 center main saddle.
Larger diameter lifter bosses to accept Chevy lifters with sleeves. This will give a multitude of sleeve options from tiny light weight custom lifters, to roller lifters, or VW lifters
Lifters removable threw outside (not that this would matter it's just for visual cam inspection)
O-ring sealed case halves.
Set up for type 4 style push rod tubes.
Drop down cam centerline from crank.
Full flow port in the side of the case to oil galley instead of rear at pulley.
No drain plate, a hammer head pick up can be attached to the pick up tube with a screen. Drain plug only.
Deeper sump with boss on each side for 1/2” fitting for oil return from valve covers.
Solid behind #3 and #1.
Hard anodized cases that are finish honed to fit after anodizing.
Larger oil transfer groove behind center cam bearing for better oil transfer to 1-2 side.
Center main, bridge the gap behind the center main bearing to the case for added strength.
Build up and radius the top of the case to the mounting flange and at the oil cooler mounting pad.
Time cert alternator stand studs.
More material at crankshaft pulley machined for a larger crank pulley seal (such as type4).

I'll add more later.
By the way thanks Jimmy111, if for nothing else just the thought. This would be very cool to have happen.

If this case goes into production, will it be sand-cast or die-cast?

Lots of good input guys.

They will be investment plaster cast. High quality. Same way you make turbine blades.

Yes, the 70 degree V4 was a project of mine. Unfortunatly there is not an easy way to do it. It requires a balance shaft to keep from vibrating the motor apart. That is why you dont see them in the USA in anything but motorcycles. A V6 is possible but wont fit in a beetle... Crying or Very sad

Yes, Pull thru. But pull thru IS better. You would have what looks like a porshe fan mounted between the cylinders like a Deutz.
I saw some interesting designs where the muffler was mounted between the 2 banks and the induction system on the outside. The fan helped in extraction of the exhaust and there was no exhaust pipe.

If I wanted a "V" motor I will get a Harley engine.

The horizontal cylinder arrangement is what made the VW aircooled... a VW. That is the entire unique characteristic I like to so much about it.

You go away from that, and people might just end up doing motorcycles instead.

The system is working fine. Just needs more meat in the proper areas.

I want to be faithful to it. You do not want to bring home a "mistress", do ya? Laughing

Eric.
The cast in oil thermostat is an excelent Idea!
I dont know why I did not think of that...... It will fit too!.
Radial Very Happy

Can you imagine that! split ports are no problem. Anyone know why they did not catch on??

i wouldnt change anything about it. what fun would it be if a 183CI or a 200+CI type 1 would just fall together. it wouldent be. this is what makes it so much more satisfing to create something from practicly nothing. could you imagine the true craftsman many many years ago with only hand tools avilible and what they created wich in some instuncess is better than what we have today do you think they would change anything i doubt it. you have got to have chalenges in this world if we wouldent this life would be not worth living. enoghf rambeling. jeff d.
