Anyone keen to wind up their boost?! (safely)

I have a 2mm shim here and a 3mm shim for someone to test out (78mm bore).

Would prefer someone who knows what they're doing as I don't really want to deal with an engine failure due to lack of technical savvy. Also looking for some decent technical feedback, I.E; relevant comp ratio, fuel (octane rating), engine specs and boost pressure, and some notes on it's general performance. I can provide accurate figures for the additional introduced volumes.

One shim is un-used and the 2mm shim has been used with a safe 8:1 comp ratio on a NA engine, removed properly so it's nice and flat. Both items are mild steel.

PM me for details, I guess if it works out well and you like it you can hang onto it (on the grounds that you provide me with some quality feedback).

I can assist with some pointers on installation and gasket adhesive to save you the hassle (adhesive is Hylomar - I have a tube here somewhere) etc as I personally installed one of these on my NA engine.

Cheers.

You can buy Copper head gasket cement in an aerosol can. Thats how I glued the shim on my engine.

Hey Thanks Bart,

Yeah the Hylomar was a little too difficult to apply evenly as it hardens once exposed. So an Aerosol would be tops. Could you recommend a brand name of the copper gasket spray? otherwise I'll just try the one the shop recommends.

Chris

you can get Hylomar in a spraycan too Chris...
I'd be up for one, but it's the high comp motor on the list first.. :) boost next..

i might be going turbo soon and ide pay for the shim ,but ive had 60thou taken off my head and its on an a12 so im not sure if it would be doable with my head

ill pay you for th shim too chris :)

I just use the VHT stuff. The can cost something like $18-$19 from memory, but I got plenty of use out of it.
