Well, my 406 SRi is now finally on the road - and I had a few things to tidy up tonight.

Dash lights - fixed
Water leak - fixed (for now)

Also fitted a boost gauge and manual boost controller. Now, it's been so long since I did anything with these engines (used to fit them to 205/306/309/405s all the time) that I can't remember what sort of levels of boost they can safely run.

So, anyone know what I can safely turn the boost up to on an otherwise standard 406? Only mods are a dump valve, cheapo cone filter and the centre silencer is removed.

Thanks.

I think the general view is don't. They never seem to last if you increase it at all.

All the old ones we did lasted just fine - and they were all pretty damn quick!

The standard ecu will cut the spark if the boost goes over 1 bar, for any more you either need to change the map sensor in the ecu and find someone that can remap it or go for an aftermarket ecu.
