Hi guys,

Wondering if you could help me.

I just tuned my MX and just wanted something safe and pwerful, so running 7lbs boost, got 140kw.

Now I would like to know for the future where i could get a decomp plate so i can increase my boost safely.

Any input would be greatly appreciated.

Thanks

Chris

What Davex3 said.

The internals are fine up to around 7.5-8.0 lbs of boost, but above that you can easily bend rods.

Decompression plates are now very old world and I've had problems with them in the past and had to resort to "O" ringing the head, which is expensive and irresversible.

If you really want to do it, you can get a few different thicknesses of head gaskets from Cometic.

As others have said it's not a great option. There is no problem making 250rwhp on a well tuned and looked after 1.6 engine without decomp. Much past that you will have reliability problems.
