I've asked James (from Piper) already what the diameter is... but I've got no idea how long it'll take to get a response

As far as I can see, most people would like it in 2010, and that's just fine. I'm a poor man at the moment and the coming few weeks are busy for almost everyone in the world... so let's keep the topic alive, but don't rush things

I'd for sure want to know the exact weight of these lifters, and I'll compare them to my new oem style units to determine if they're worth the cost.

58 grams per lifter without the shim.

I thought that was something you just read somewhere from someone who had them, not what the manufacture said

The ones I've got access too are owned by the guy who posted those numbers. Jonus posted that data after I asked him to. He used a digital scale to weight them. The original pictures had the scale used in the picture I believe. Its been a long time, and he still hasn't installed them *chuckle*

I am interested... However, I just ordered the OEM replacement lifters in that G.B.

In the future I want a performance cam and would love a set of solid lifters. I am building my engine with a used cam at this point, yet have not sourced new adj. screws, which may be tough.

It will depend on my finances, when things get closer to a buy...

So count me in, sort of...

wow thanks Min!

So the OD is 10mm. Those look a lot like the shims used by Alfa Romeo. I checked those a while ago and they fitted great on the valve stem of the 931 (and 924). I wanted to machine the stock lifters to fit those shims instead of the adjusting screw but it's not a great plan. Those shims were 11.5 or 13.5mm iirc (I'll check tomorrow, but I'm sure it isn't 10mm)

As far as I know, this isn't a OEM size which is used by manufacturers.
Isn't a problem though...but it would be great if you could go to a regular dealer for shims

edit: Ok, the valve stems are 9mm, so I'm not sure if they should fall into the shim, or that the 'cavity' in the shim falls over a notch on the lifter.
If the valve stem has to fit in the shim, the ID should be at least 9mm and apparently it is 8mm.

I think the lash caps or shims fit over the nub or crown on the lifter, not the valve stem (remember, there's a stem seal there...). If they fit on the stem, you'd have to take into account what size stem you have, e.g. my valve stems in the UWB project are 8mm, not 9...

OE lifters weigh 78gms per piece.

Adjusting screws 6gms each.

Anyone got a weight on the Newman units?

I'd also like to mention that the nub on the lifters is like 7.7mm, the hole in the shim is 8mm, so not a tight fit. I think we just dug up some 5/16 chev shims or some such that fit just as well and were going to use those on this installation.

So...time for a quick kick. Haven't heard from Piper since the last time

Can't give a clear price, so just go worst-case scenario.

Anyone changed their minds? I'll be contacting piper probably end of the month and telling them how much participants there are. If there are two others besides me, it's fine by me. For my own calculations I'm using the highest prices for everything to be sure it can only be cheaper than calculated.

For the shipping costs from me to 'outside europe' it'll be €20,00 below 2kg (which I'm sure it is).
Additional costs will be the paypal fees (which is a percentage of the total), and shared shipping costs from the batch from piper to me.

The whole problem is that there isn't a clear price at the moment so if you add all the costs (including VAT??!) there should still be some margin.

This makes the whole group buy crap, so that's why I expect that most of you aren't interested. If there are two other buyers it totals to 3, which is the minimum limit for piper to produce. If piper has that information and produces, it can be distributed through me, but perhaps also directly through piper (which turns this group buy into a distributed buy from piper

). Not sure if piper's willing to sell to private sellers. If not, it goes through me and adds a bit to the shipping costs.

Quick calculation:
200 pounds (229 euro) listed at piper
17.5% VAT? = 35 pounds (41euro)
Shims 8pc = 32 pounds (37 euro)
17.5% VAT? = 6 pounds (7 euro)
Shipping from piper to me = ?? dunno?? let's say 40 eur max depending on # participants, so let's say ~ 10 eur per person
Shipping from me to you = 20 euro (less if it's in Europe)
Paypal fees = 3.4% + €0.35

That sums up to (in euros):
229 + 41 + 37 + 7 + 10 + 20 = 344
An additional 3.4% comes to that for that nasty paypal gives 356 euro.

Keep that price in mind as indication. Could easily be less if there's no VAT or if Piper gives us discount (which is based on number of participants) or if you're not outside EU. The chances that it'll be more are slim, but it won't exceed 400 (yeah I keep the margins big in my calculations).

I converted currency with
http://www.xe.com/ucc/

Wow. that's almost $500 in USD. Seems much but then again...these things are absurdly expensive.

I'll be keeping track of who's joining in the same style as Dan does. This is a list of people who are SURE they'll participate, so you won't be on if you're not sure or want to wait for definite prices... the price is definite when I tell piper the number of participants and they give me some solid numbers. List is open until end of February.
This list will be kept in the first post.

We may want to wait until we hear back from Steve @ Integral...
