Reliable N/A 225-230hp type 1 engine?

[-Alex-]

I asked from Berg, they dont make anymore special order cranks, even if its listed.

Try Roger Crawford at heads up performance, I got one of his cranks for my 2789cc pauter street motor, Nice piece, makes a scat bilet crank look rather average.

I have contacted him, but i havent got answer yet.  I even did 3D cad modell

If I do a engine for my Barndoor it will be,

WBX convert to OXY!
88mm Chevy journal t4 main flanged crank.
5.88" Eagle rods.
Rolercam and lifters. (FK89)
101.6 cylinders.
A/F heads or MS230 heads.
BIG HX40 Turbo.
Halltech.
Cranktrigger.


This is not a N/A engine with only 225-230hp

Why a roller cam like FK89 ? That cam grind does not need roller lifters ... But if you want one i have a roller cam with FK89 grind for sale :-)

Roger can be hard to get a response out of, Maybe try calling. He always comes through, hes just a little slow.

[-Alex-]

Roger did answer, he can have made it Still waiting answer from moldex. Always gotta ask from at least two places

[-Alex-]

Yep, but its not welded crank and it is 86 stroke -  I am not going to argue with nobody about this     Still it is a lot of money, but i have to think.

Dam, all that money and time and all you need to do is to convert a WBX case and use a WBX crank for the best combo available. Remember - you`re only after 225 - 230hp. A result that was achieved years ago and with several engines to prove it. You do not even need IDA`s to do it:

You could copy the receipe I mentioned in the first reply here but be aware, you would end up with more than 230hp. Or for a interesting Oxy boxer thread you can read this on our Norwegian forum:

[-Alex-]

Newer know if there is more than 225hp.. Heads MS230, JPM 282@0.050" cam, 1.4 rockers, 2386cc, fuel injection. Also TF-1 case i am thinking. I havent seen personally TF-1 case, but i have heard mostly good about it.

BB, I think it will be similar combo as on your first post. I like this also:

The one in the link is a LOT of money and I have a hard time understanding why you should pay a small fortune for a exotic engine with 253hp when you can achieve 245hp using off the shelf parts. It is NOT the fancy parts that will give you the HP - it is the build.

I rest my case.

[-Alex-]

Yes, some fancy parts will not give more HP, only tad more reliability maybe 

[Torgeir Schibevaag]

Some of the engines linked to in this thread has been driven, and driven hard for years now...  How reliable does it nead to be?

The way i see it you ar more concerned with the name of the parts, than the goal you have set yourself.... wich in all respect it fine, but you may get dissapointed  if you ad cost/use into the equation...

Roger's cranks are real nice and look strong....

Just read through this thread..
A "easy" solution for the target 225hp would be:
WBX case AND crank. Best crank there is.
good rods
correct camshaft.
101.6 pistons and cyl.
MS230 101,6 heads with WBX stud patern.

No need for a §§§§§§§§ crank when Volkswagen already has made one for you. use the money on the heads instead.

It was surprise that moldex custom made 86 stroke crank is actually a lot cheaper than heads up perfomance (Roger Crawford) one. Well, about 700 dollars cheaper.

I like one piece cranks more than welded cranks. But i have not heard anything really bad about welded cranks. And TF-1 case is not so expensive any more.

[-Alex-]

When using 101.6mm pistons, then there is no possibility to use doghouse fanshroud. Does doghouse wide fan fit to aftermarket non-doghouse shroud?

[karl h]

it is possible to use a doghouse cooler on a wbx case (or even a type 4 case) using a type 1 cooling setup. you have to route oil lines through the fanshroud and connect via a sandwich thermostat from the oil filter. sounds more complicated than it is. the cooler can be suspended on the shroud, so you dont need the boss on top of the case
got a drawing somwhere but cant find it

[-Alex-]

Okay, i have seen that kind of setup, i think Stripped66 had it once.

What do you think, does these 101.6 cylinders have enough fin area?

Stupid question, but how much would be power difference between 86x94 and 86x101.6 engine, if same cam and heads etc are used? 
Haven't yet heard any problems with 4in bore engines, is there any?

[Tomi]

Those cylinders are far from round, I've had 2 sets. I have stress plates for honing and can borrow them if needed.

As you know you can't use same heads with 94mm and 101.6mm cylinders. But all other things being equal the heads will flow better with 4" cylinders due to more space between valve and cylinder wall.

[-Alex-]

I have heard too same problems. 101.6 nickies would be good choice, but  they are custom made, not much more expensive than normal nickies, but still expensive.  With the 4in bore, everything looks so thin, except cylinder walls.

[-Alex-]

Does 101,6 cylinders cool as well as normal 94 cylinders? What is their wall thickness?

[Zach Gomulka]

I'm sure the fin area is much less, so my guess would be no.

Rocky Jennings made the oil cooler adapter that I used to run in a dog-house shroud (I'm now running a POS Bergmann 911 shroud...). The adapter bolts to the deck of the case on the 3/4 side, which means you need to drill and tap the case to mount the adapter.









If that's not your cup of tea, a block of aluminum and a couple of hours on the mill should turn out a solution.

[Udo]

What heads do you have ? Or did you relocate the stud holes on the case ?

Eccentric case inserts.

[Udo]

That's nice , in my opinoin and experience it is the strongest engine combo

What flywheel bolts with WBX style cranks? Are dowellpins needed? I was thinking these bolts:

Uh, also found this video about chinese vs. german t4 flywheel

[Jon]

This one is running stock used bolts:

[-Alex-]

Yeah, i calculated with using solidworks that type 4 attachment is at least 50% stronger with these bolts than type 1 wuth 8 dowells...but thats just in theory.  Nice car BTW
