1.6 8v decompression plates group buy?

[bazil]

would there be any interest in this? they are made to order and avalable in different thickness for different CR, at the moment the price for a single plate is around £115, the company says you only use 1 head gasket and the plate is bonded to the head with a high temp non setting sealant.

some say the E16SE plate caould be used on C16XE/X16XE aswell.

[scorge01]

how much for these as group buy? as im interested in one.

[bazil]

im not sure yet, i am looking to get numbers before asking the company, if you think how much low comp pistons would cost ( 400-500 for forged low comp for the 1.6XE's ) then a 100 quid plate is cheap.

[dougie_boi]

a got one priced from egay for around 55 posted

[bazil]

did you remember the seller?

[dougie_boi]

2 secs il get a link mate

[dougie_boi]

this is a saxo one hes selling mate his name is profilemen ive sent u the link just incase spudders a bit peckish and scoffs it pmsl

[bazil]

found some and they seem to be stainless steel ones, the ones im looking at getting are aluminium alloy and act as an extension of the head so only one gasket is used not 2 as with a steel plate.

Bazil I may be interested in one to build another engine up pending price.

this is coppied from the ebay advert,



Laser cut quality stainless steel de-compression plate.

If you are planning on either supercharging or turbo charging your normally aspirated engine you will need to fit a de-compression plate.

As we cut these ‘in house’ it allows us to be competitive on price and often far cheaper than other suppliers.

To decrease the compression of an engine you need to increase the effective volume of the cylinder heads, we offer three standard volume increases, an other sizes on request.


<LI class=MsoNormal>3CC’s <LI class=MsoNormal>6CC’s
9CC’s
Please also be aware that when you calculate you volumes you will need to allow for the use of two head gaskets – one either side of the de-compression plate. It is generally considered that a head gasket is worth about 3 CC’s.

PLEASE STATE CLEARLY WHEN ORDERING WHICH SIZE YOU REQUIRE!

If you need assistance with the calculation please contact us.

this is coppied from the ebay advert,yeah but i spoke to the guy direct mate and he could make one up that was a precise machined fit only requiring one gasket as i was thinking something simaller with a 1200

[bazil]

i have a steel plate atm, iirc it's 1.5mm but im looking at a 2mm aliminimumumnum one to eliminate the 2 gaskets, i dont want to put a steel plate against the head,

[burgo]

can you choose the material used? i would rather have a copper one as i have fitted one before and therefore know for a fact they are proven to work

[bazil]

Yeah they do copper head gaskets but I was advised to use the aliuminimun alloy sealed to the head,

[burgo]

the copper ones sell to the blocks so if anything is going to fail it would be the head gasket as normal

[MK999]

the copper ones sell to the blocks so if anything is going to fail it would be the head gasket as normal

Well the next weak spot after that is the ceramic cores on spark plugs, but if you manage to blow one of those out you're doing well lol

[bazil]

Same as the alloy plate as you still use a gasket on the block,

[burgo]

Same as the alloy plate as you still use a gasket on the block,i know i just believe that with how much ally likes to move about having a gap between two layers of it seems a worse solution to me

Here is the email I received,

Hi Allan,
Thank you for your e-mail, there's some info about decomp plates attached for you to read.
The E16SE drawing is on file, so no need for you to send me anything, all we need to do is decide plate thickness.
Assuming that your starting CR is 10.4:1 (please check this, if different I can recalculate) then you can choose a few CRs between 9.8:1 & 7.9:1, though a good starting pont may be a 2.0mm plate to give 8.5:1.* If you've got a different figure in mind please let me know.
For this application the plate should be made from aluminium alloy (see info), cost is £110.00, high temp non-setting sealant is £12.00, P&P UK Mainland is £9.50.* All prices are totals, availability is usually within a couple of days, and all prices are totals.* Orders can be taken over the phone or I can send a secure PayPal invoice that can be paid online with any type of card.
All the best.

What's up with using 2 headgaskets ? Both of Craigs engines never had any issues

[bazil]

Planning higher boost edd, I've looked into vxr forged pistons and steel rods, it'll give me a 8.5:1 CR but cost near a grand and a full bottom end rebuild, so the cost of the 2mm plate really looks good, maybe get the pistons and rods in the future

[Edd]

Why would higher boost pop the headgasket if decent one was used ?

Think I'd rather have a gasket than sealant

[burgo]

Think I'd rather have a gasket than sealantthe sealant is only a tiny smear over it, any more and its squished out, not ideal lol

[bazil]

Basicaly you don't need 2 gaskets with alloy or copper but you do with steel, I'm only going on the advice of the supplier ATM

[burgo]

i assume the supplier is ferriday? if so consider me a recommendation.

[bazil]

Yup, plenty of info on there,

[bazil]

2. scorge
3. comptoncj
4. vx kev
