Posted: Wed Sep 26, 2012 12:57 am Post subject: Booleans 2332 turbo DD |
|
|
This is supposed to be the engine for my DD bug.
Body is from -56 on a -68 pan. A lot of restoration is needed on the body, but the pan is as new.
I will be working on everything at the same time, which will make for slow total progress. (This includes restoring the house and garage at the same time).
Slightly dynamic spec at the moment:
WBX case modified for aircooling, 8mm studs.
SCAT Volksracer crankshaft, 84mm stroke, Chevy journals.
SCAT 5.700" H-beam connecting rods, Chevy journals.
ACN Max Turbo dual port cylinder heads, (L6T heads) 42 X 37.5mm.
94mm AA cylinders - still looking for suitable pistons.
Web 86A on 112 degrees. May adjust In/Ex ratio with different rockers.
Web T4 hydraulic lifters.
CB 1.4:1 ratio forged rockers.
ACN Heavy Duty aluminium pushrods.
Fuel injection - Bosch LH-Jetronic 2.2
Turbo - T3/T4 .63 turbine, 48mm compressor.
Intercooler - something cheap.
Full OEM tinware.
Suggestions on this combo is very welcome! _________________ I strive for perfection. Excellence will not be tolerated!

Yes, began doing that 25 years ago. Actually, the newer ones are problematic for me as I haven't worked professionally with tuning for almost 15 years.
It's not that I think it is better or so, but I still have ECU's lying around.

Hi Cheap , please over load us with pics of your oxyboxer build, its something I've been interested in doing for a while and may do once the other engine builds are done _________________ Aust. RHD 66 Type 1

Will do. I just have to find a few donor engines. Without paying half of new price at the junkyard... _________________ I strive for perfection. Excellence will not be tolerated!

I would use shorter rods for a daily driver. Better bottom end.
You don't want to cut the 56 body do you?

Regarding rod length - swept volume will overcome all negative effects, but that said - 5,7" isn't very much with 84mm stroke.
I aim to use pistons to achieve stock width.
I'll cut it as needed, but don't think much will be necessary.
Hey, they made millions of bugs - many, many thousands are still rolling on the roads on all continents.
If I give it a new life in the shape of a racecar or modified street car I feel no shame at all. _________________ I strive for perfection. Excellence will not be tolerated!

Have been aching over the spec for a while now: Current idea is to use a welded WBX crank instead. That would give me 83mm stroke with VW journals. Fair enough.
Have an idea to use the extra space in the case to use bigger cylinders.
I think I can get away with 96-97mm bore if the head is modified somewhat.
I'll get back with more detail on that one later.
Anyone ever used T4 cylinders on a T1 engine? How long are they?
These might be something to try - will probably have to remove a few fins on the outer end though... http://vwparts.aircooled.net/Piston-Cylinder-Set-96mm-x-80-86mm-JE-FORGED-T4-p/vw9600t4sb-je.htm This would give me 2403cc. _________________ I strive for perfection.

T4 cylinders are fairly short compaired to a T1Probably close to an inch shorter.

I dont think you have the space between the cylinders for that. Its possible but you will have to do some milling at least on the cooling fins.
Jeff Denham does this so perhaps you should talk to him.

youre putting a snail on it.. why such a huge motor? If you can tune you just use the turbo as its intended.

Thats the problem.. most in air cooled land cant tune well enough to do that. If they can the next issue is that they cant or wont afford a trans good enough to hold it.
This setup tuned well would put 300 to the tires all day long on less than 15 psi.
But with cheezy management and cheezy tune... never gonna happen. So people build a HUGE engine and run low compression and low boost and shit fuel management and hope they are happy with the power level. _________________ Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.

The project is a journey. It doesn't have to be rational or politically correct.
I believe I can tune it a-ok, but it remains to be seen of course. The interesting bit for me will be how the cam/lifter combo works. And using a WBX case - never did anything like that before.
Too bad about the T4 cylinder length - will look at other possibilities.
I would be severely depressed if it cranks out only 300 horses at 15 psi... It should really be between 330 and 350. _________________ I strive for perfection. Excellence will not be tolerated!

Well definitely post vids of dynoing it when its done. Id like to see what you put to the wheels for sure. _________________ Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.

Yeah, because boost collapses lifters. _________________ Build thread: http://www.thesamba.com/vw/forum/viewtopic.php?t=212747

Of course, everyone knows that!
The point with hydraulic lifters is a quiet engine. I like that.
I also like a relatively low revving engine with massive torque in my dd.

If you can get that 350HP engine working, you should just be able to back it out and melt the snow
Get your priorities right. |

I believe...... type 4 cylinders fit right in the case since they have 100mm bottom, and the length is OK(matches the much higher deck of the case), except the stud holes don't line up, AND they hit the water jackets .
The WBX crank is X drilled, I don't think you can stroke it as far as you think without the oil hole being on the edge, but you might call DPR, he may have some methods for it. |
