looking for chromoly components and their vendors/manufacturers for our engines. More specifically for the 1.6 TD. Anyone? I found maxspeedingrods, but wonder if there is anyone else competition etc. As well as other components. I may have someone make me a forged CNC AAZ cyl. head as well, but before he will do it he wants interest ......... LOTS! of interest ;)
-
I want to say that Crower makes rods for the 1.6, but they are X-beam(good for high RPM, but not as strong as H-beam) and cost around $800 a set.
as for the head, a cast iron one would be more than sufficient(and cheaper most likley) and I would love to have a steel(or iron) head, but the cost would likely turn me away from such an item.
the cost of the crower rods has kept me away, because $800 is alot of money to put into other parts of the motor, and likely the thousands that an iron head from a limited run would do the same to most on here.

there is someone i have heard of that has a cast iron headed 1.6 and is running like 80 psi boost? i heard that somewhere. not sure as to how accurate it is, i never saw it.
-
buisness is bad and some machinist's are hard up for work, I bet if we bought all of the raw materials my guy will work with us. ???
-
a ballpark estimate would still be needed from the machinist before anyone even thinks about getting an iron head.
what you should do is talk to your machinist friend and see what the cost per head(including materials would be) for a run of 10 heads, 20 heads, etc...
then we can all make a decision about wether we want to save up our pennies for one.

it'd be cool to see some iron heads. i doubt it is remotely cost effective tho. it will be interesting to see. but how much is a new aluminum head?
-
You can buy a new casting for around $300.
-
Ok, so here is the deal, he needs junk head/cad of the heads we want as a pattern to take a look at for prototyping. He suggested that chromoly would not be cost effective and that stell would serve our purposes much better, and it could be possible if he can take a look at the water jacket. I'm thinking a run of mech aaz heads and hydro aaz heads, what do you guys think?
-

I can assure you that such a beast does exist. I'm not sure how much boost he is running though. He's a member on the board and I don't want to go spoiling someones secrets so I won't say more then that.
-
how much power do you think he can squeeze out of that iron ***? ;D
-
pretty sure you could make alot of power with an iron head, it moves the weak point of our motors from the head to the rods/crank. with the aluminum head 200 HP seems to be the ceiling, so with an iron head, 250 would not be out of reach.
again, a ballpark price would be good before anyone gets too involved with this.
that being said, I would be very interested if it is something I could swing financially...
-Owen
-
well I need some cad files or a digitized way to get it to him, or someone that can do it. Possibly someone who has access to a forge? I have a junk head we can cut up to see the waterjacket but the Machinist is a pro and wants to do a computer model for weak points and to make improvements on VW's original design. Possibly even make a Mech head for aaz frankenbuilders so that there will no longer need to be a conversion etc.
-
well, you have a head to cut up, so you are ahead there, but you will need someone to turn that into a 3d model.
can the machinist do that for you, or are you looking for someone else to do that?
I am good enough at 2d modeling, but I would not be confident making a 3d model of something like that.
please do all that you can to make this a reality, I am willing to do all that I can to help move this forward.

i am very much interested as well, an iron or steel head would be amazing :), much ,much more power potential
-
I sell to 4 of the biggest grey and ductile iron foundries in the state of ohio. If there is volume I can get a great price. If there isn't I should still be able to get it done for the best of anybody. I got some amish guys in at 2 of these foundrys making short run peices for them. Silly I know
-
Seems ironic that the V8 crew are all ditching their iron heads for better performing aluminum ones, when over here in the IDI world we're talking about ditching our aluminum heads for iron ones... ;)
-
should just make hydro aaz heads, u can convert hydro heads over to solid already anyway.
-

yeah, that would bring the price down, as there would be only one casting needed.
-Owen
-
itd be nice to if he made a one though that did not have the extra oil drain but was made from the same casting, that way anyone could easily run this head. thats how the amc heads were made.
-
the solid lifter heads still had the bump but the drain wasn't drilled out
-
I will ask him, I'm sure something as simple as this will not call for a different casting, just a modification, if it is a cost issue I will stick to the hydro idea. 8)
-
I would buy an iron head ;D Always looking for something bigger better and faster!
-
I will keep the comp stock as putting the aaz head on a 1.6 already has it at 17.5/1 And thanks for all of the advice, but we already talked about all of that and more.... yes, I said more. I don't want to get anyones hopes up so I won't say much more.
-
I already kinda hijacked elsewhere, but thought I would post it here for posterity. Whay kind of losses are there in the x-beam rods as opposed to the H, or I beams? The reason I wish to know, is that I would love to run X-beams in my setup because of weight, however, I don't want to run them because I have heard that they are not strong enough to handle the stresses of 40+ psi is there any merit to this? I realize to make them as light as possible they simply have les meat than I or H beams but I think that the weight difference "for my application anyways" will be worth the risk
-
why do people worry about the swirl chambers falling in, they can't fall in unless they break into pieces, and when they're broken it doesn't matter if they're peened in or not.
-
thats what im wondering. they have to come a long ways out of the head to fall out. or the face has to crack off. a pre cup sits about a half inch up in the head tho.. i never understood how one could just "fall out" with the head torqued down and head gasket in place..
-
securing the cup doesnt do crap if the face cracks off...
its still lights out Irene for your engine...
-
Screw in precups. Then they shouldnt fall out. You might have to run washers to index them..but eh..its an Iron head.
-
nifty idea, but how to make them face the correct direction?
-
"washers to index them" lol.
indexing them is so they all face the same direction..
-
How would you get them the same height then?
How common is this problem of dropping precups? You might be focusing on an issue that doesn't really exist.
-
it doesn't exist imo. the only way it can happen is if you are burning serious amount of oil or if you have a really bad injector. and even then a threaded or peened cup won't help you.
-

Getting them to the same height would be a matter starting the threads in the exact same spot on each hole. You can have the pre cups stop in the same spot by stopping the threads in the same place. The precups threads would also have to start in the exact same place. It's called ENGINEERING (in jun ear ring) ;D

injun is a slang/racial term and by the fprum rules is not allowed, and for the record I have never seen one wearing an earing.

well I gues you never saw me just outta the Army, I had an earing just like a sailor. :D You jarheads are so slow on the uptake sometimes. ::)

Let's steer this thread back on course.
-
but seriously you can engineer the head and precups to match up, but the important part by far is the machinist and his tools. Easily do able as this type of job is commonly done in the aircraft industry.
-
Aircraft huh, I may know somebody for that.
-
so is the iron head idea going anywhere?
-
yea, we need boost-limitless heads..
