YOUR pipe dream engine combos

[Chickensoup]

How about we dont derail the thread again . Nobody cares which is "better" or what makes more power. If you want a discussion make another thread.

How about a simple mild turbo engine? Stock plus, with a small turbo tucked where the muffler normally resides. It should add a little power and really overcome some of the limits of the long stock intake manifold and small carb.

Start with a stock SP or DP engine (or perhaps a 36 horse for an older Bug.) Replace the exhaust with a header feeding into a small turbo sized for an engine that rarely exceeds 4500 rpm. Boost reference the stock fuel pump, o-ring the pump pushrod. Likely need to rethink ignition, but looking stock enough. Stuff the 5-6 psi output of that into the stock carb. The idea is nothing expensive, very drivable, just perhaps 10-15 extra horsepower. I suspect a good late Mexican style filter oil pump should be a part of this, turbos being sensitive to crap in the oil.

I'd like to stick that in my buggy. The 36 horse version would be too cool in my '57.

[Floating VW]

Wow, I just want to say I got the biggest kick out of reading this thread, especially the last four pages! It so reminded me of what I went through when I set out to build my own pipe-dream engine (NA 76mm stroke x 83mm bore with as light a valve train as possible). Everyone I talked to about the possible pitfalls of building such an oddball mule all said the same thing: square engines were a bunch of hooey, and I'd do better with a 1679 or a 1776.

They couldn't have been more wrong! Of course, they all assumed I was looking for high RPM power (in which case they might have been right), but I wasn't. I was after low RPM power and a torque band so flat you could eat your lunch off it, which is what longer strokes give you.

P.S. That article about stroke vs bore- https://rehermorrison.com/tech-talk-53-big-bore-or...USn6dT1FuE -isn't terrible, but there are some glaring mistakes in it. He's right when he says the mechanical leverage is greatest at the point when the connecting rod is perpendicular to its respective crank throw, but this doesn't occur anywhere near 80 degrees (at least, not in an ACVW). In a stock 1600cc, it's closer to about 63 degrees. Increasing the stroke decreases this angle, for example, a 76mm stroke reduces it to about 61.5 degrees. The smaller the angle, the more the engine is capable of using peak in-cylinder pressures to produce torque. Smaller bores also help reduce the loss of in-cylinder pressure as the piston moves away from TDC. He probably got confused with max piston velocity, which does occur close to 80 degrees ATDC (76.6 degrees in a stock 1600, to be exact). Also, if he is saying peak in-cylinder pressure occurs at 30 degrees ATDC, I would say he needs to advance his timing by about 10 to 15 degrees.

i wonder... how hard it would be to have a set of 2 stroke cylinders made for a vdub.

has anyone heard of a 2 stoke type 1 or 4?

either than or make the cam a 1:1 drive like the detroit 2 stroke diesels

like heres an LS 2 stroke

thats easy!! 2.7L Porsche RS flat six...

but really

2276 I think

Aluminum bubble top case
Scat crank / Rods
CSP 94mm pistons
came would need to make good 2500 to 6500 power
CB 044's with type 3 mani's done up right
Dual dell 45's
cb magnaspark ignition
lightened flywheel .


i guess a SOLID performer is what i want, something i wouldn't be concerned running in 110* heat . Its a VW engine doing what it was never designed to do..

Pauter SuperPro Big Block

https://pauter.com/parts/super-pro/

The tremendously strong foundation provided by the one-piece block, the cross bolted main caps and V-8 sized journals of this innovative engine permits the use of all forms of induction and all fuel types. Amazingly, crank strokes of up to 96mm (3.78″) and bores of 108mm (4.25″) can be accommodated, giving a maximum displacement of just over 3.5 liters (215 cu. in.) Dyno results on one of our own turbocharged methanol (no nitro, no nitrous) version at 35 lbs boost produced over 980 hp and 780 ft/lbs torque at 7400 rpm and 6800 rpm, respectively. Pauter blocks are also available in a number of bore sizes and head stud patterns or our Uni-Block model which features a 94mm bore and small point locations for Type 1, ARPM 3.0L or AutoCraft 4″ stud patterns. This from a package very close in overall dimensions to the 92 cubic inch original.

I feel that a 2T type1 motor could be done. There wouldn’t need to be a cam, so the pushrod tubes could acts as passages for the transfer ports. Although, there would need to be massive amounts of filler taking up the extra space in the case to get the correct case compression to push the mixture through the transfers. The top of the case is unobstructed enough to have proper case induction. From what I’ve seen others do with a T1 engine, I’m sure it could be done.

[mark tucker]

super charge it, no need to pressure ize the case.add turbo for more boost if you wish it. you could exzaust it through the cylinders or the ex valve. many ways to skin cats.even intae and exhaust on the cylinders and no heads, just a plate...with sparking bolts screwed in ( finned of coarse) then no worries about valve float.or pushrods, springs, good valves not required at all.
