Finally Flywheel info

The 1UZFE EGR Delete Kit is available for sale here.

The problem is not the machining, it's how cast iron behaves. A few quick points, do I doubt it matters :D

Cast iron VS "billet". A cast iron atom have a much weaker link to it's neighbor compared to a "billet"
( forged ) iron atom. This is reflected in how a cast iron and a "billet" flywheel behaves. Cast iron will not
stand up to serious abuse. Please read my first post in this tread, it's fine behind a stock engine with a
stock clutch, everything else I would not recommended, nor risk, and I do speak from experience.

Let me try an analogy. A wooden boat is a vessel floating on water, the problem is it's not homologous,
I'd call it a collection of pieces of wood floating, ( more or less ) in the same direction. The different
piece of wood is not to well linked to it's neighbor piece.
A fiberglass boat is homologous in that the hull is made in one piece, the different pieces
( fiberglass tread/mats ) is "linked" better to it's neighbor

Why would car manufacturers use forged "billet" flywheels on some models if a cast iron flywheel will do ?
Ford with all the Sierra and Escort Cosworth engines and BMW with the M series engines comes to mind.

Finally, can you do me a favor and read up on cast iron VS forget iron behavior and characteristics ?
This is not me being difficult, I'm trying to save somebody else from a lot of pain. What you do to yourself
I can't do anything about, but you trying to pass off a cast iron flywheel as "just as good as a billet,
forged flywheel" I will not have any part of, and I will speak up against it.

so in otherwords, NO CAST FLYWHEELS EVER!!!

This thread has turned into a bunch of scare mongers!

EVERY cast and billet flywheel goes though pretty much the same machining process. So if you have a flywheel with holes in it, you had better beware. Because at one point and didn't, and now it has been modified. Tsk, Tsk, Tsk.



Well here's some food for thought. EVERY cast flywheel i have had crack tested HAD cracks. All used, all fairly high km but every single one!! The one and only time i used a lightened cast flywheel (the 1st engine i ever built) it had cracks easily visible to the eye at the 1st clutch plate change.

If considering upping the redline or going with a lightened flywheel, a specifically fabricated billet is the ONLY way to go. This doesn't have to be expensive, these can be found readily for under $300US.
 
Autronic, you did not read my posts very well and just kind of jumped in. If you did you would know that I stated several times over that cast is NOT as good as billet. I know all about the makeup and the process of cast vs billet.

My argument is that my MODIFIED cast bellhousing has not lost any structual integrity than a STOCK cast bellhousing.
 
Eish!! what an interesting thread!!

think me need to add something to this!!

yes cant iron and other materials like EN8 or EN9 or even EN19, have different properties, the cast is the one that offers the least amount of strength!!

how much less, me have no idea!!

however do have the following to offer

have a handbook at home that has the formulas for flywheels, and all kinds of explanations!!

will give you guys the formula, and you guys can have fun with it!!


maybe that will help solve the issues!!

:D
 
Got a phone call from UPS this morning saying I will have a package from LC Engineering being delivered today. Sure enough 3 hours later I had 38 lbs of pure sexy delivered to my doorstep. This thing looks awesome.

sorry to quote, with pics and all however, need a little bit more info

what diameter is that flywheel??

sorry tried to send you a PM, however said you have opted not to get PM!!

hope you are able to help!!

thanx
Fernando:D
 
The flywheel is the same size as any stock 3VZE or 5VZE flywheel. I can measure it for you if you like. It uses a 10" clutch set up.
 
thanx for the offer, however it appears that I will be getting a flywheel of the same weight, 17.3kg

things have moved very quickly, have the 1UZfe on the back of the Courier, just need the mounting bolts for the engine stand and then will start doing some more cleaning up!!
and the further preparation!!

self see this being up and running December/January, long time, yep, Rome wasent built in one day!!:D
 
Fully agree there. I may actually consider it for my application, since I do plan on running up to 8,000RPM on a cast flywheel, with some big cams, I could even run higher. Below 7500, on a unmodified setup, I wouldn't bother.

You ever get this bolted up? running? good engagement with starter/ring gear? does LC have the specs saved somewhere?
 
I was not at home when I posted the first measurements, they were from memory and were
correct, it's good to see I'm not gone completely senile....

Anyway, a few more:

- Center hole ( to steer towards crankshaft ): 42.02 mm

- Starter ring placement: 14.0 mm up from the crankshaft plane and 272.02 mm diameter.

- Max diameter before the starter will hit the flywheel ( behind the starter ring ): 294.0 mm

The rest is personal preference
thanks this is what i was looking for
 
yea no kidding not as easy to find as you would think. i put together a flywheel last night on solid works mostly done just need the bolt pattern to the 5.0 chevy 305 clutches there 10.5 inch and cheap... i also need the id and od of the findeza insert so i can put that in as well. anyone know this by chance.. thats probably a better question for a chevy forum...lol
 
and the thing is I used to have a link to a company that sold just ring gears and I lost it. I guess I'll have to talk to a gear hobb shop. and no, that isn't a misnomer...
 
tom steele:

Be careful with your choice of 10.5" pressure plate as the outside diameter of the 1UZFE ring gear is
305 mm and the inside of the bell housing is not that much bigger.

From this PDF file I found at the Centerforce web page it looks like the Mustang 1986 -> 10.4"/10.5"
pressure plate is the biggest you can fit inside the original 1UZFE bell housing.
The bolt pattern is 11 3/8"
( 288.93 mm ) and uses M8 bolts, so the outside needs to be at least 300 mm.
