Any1 using a low compression plate or pistons?

whats ur spec and bhp with either of these?

 

bid diff between a plate (dodgy) and pistons.

 

whats cheaper?

was reading a old fast ford mag, chap was running a zvh with standard bottom end with a low compression plate, 2 felpro head gaskets, 218bhp @ 8psi

 

multiple headgaskets blow , plates melt and move

im using Mitsubishi Tredia Turbo 1800 pistons 80.6mm , shit cr of 6:1 but i could boost to 2 bar with 102.7 octane
i made 150kw atw at 1.5bar
donkey sub 3k , monster above this with a t34 and modified cvh 22 cam

 

I was running a a decomp plate on my standard RST engine without any problems at all. Had to use it as head had been skimmed too much. You wellseal the plate to the block and then use a standard head gasket on top of that. I also put wellseal on both sides of the head gasket with every engine I build. I got mine from http://www.ferriday.co.uk/ did the job superb.

 

did u run more boost or just use the compression plate cos your head was over skimmed?

 

I was running 18psi of boost without any problems for a year. Only stopped using the engine after oil pressure had dropped and found it had a worn crank.

 

forgot to mention. If you get a cheap one they won't last 2 minutes. I paid £80 for mine with the head gasket.

 

You can get by with a decomp plate but most people consider them a bodge it way of lowering the compression.

Felpro headgaskets are shite.

 

is it for a zvh?

 

if you mean me, i was looking at this route for my cvh still 1.6

 

so if you wan to build a budget zvh, then you could use say a 60 tho mile block, decomp plate and cvh head...and all would be ok?

 

i know of a 1.6 cvh which makes 256 bhp at 13 psi and revs to 7k

that zvh most likely made its 218 bhp at 5000 rpm peak

 

6:1 c/r that must have been 'fun' (ZZZZZZZZZZZZZZZZZZ) to drive/bit like my old FS1E with the HT cap off.
