Internet works out here you know!

Typical dawes device, yes it will work fine, would be a little obvious to an insurance assessor of course, with that you can raise the boost within the overboost fuel cut, you can go above the cut limit if you use a FCD but risk increases rapidly!

Thanks Simon. Now I know what a Dawes device is too :icon_biggrin: I guess a turbo pressure gauge would be wise if I fitted this? Apart from the engine cutting out, what are the ramifications of hitting overboost (>0.8bar) while the Dawes device is being setup? Hope the weather in India is good enough to make up for you missing out on the unmentionable white stuff. Tony.

Back in blighty now, still on jetlag time!
Temperature in India was 18C MINIMUM, max 31!
Best to set with a boost gauge, the boost cut is nasty to hit, but otherwise not a major issue, you could do it without the guage, but it would mean making a small tweak, doing a few runs and if no cut tweaking it a bit more and so on.

Aim for just under 0.8bar.

Correct-ish its not a direct hard cut though, it will allow a small amount of overboost, so as long as its not 'silly' it should be OK.

Ghetto mod

Simon. Just had a thought, should I reverse the ghetto mod and go back to the standard piping if I am going to fit an MBC? Coming back to Blighty from 31 degrees must have been a shock.

You need to plumb the dawes in the direct line to the actuator, so ghetto mod and stock BCS become redundant.

MBC and TD04L fitted, whoa Nelly. The instructions for fitting the MBC were very unclear and took me all day to work out which part of the manifold I was supposed to be taking the feed from (perhaps I am just thick), suffice to say I have experienced the fuel cutoff thingy under hard acceleration, a bit scary. I have a boost gauge fitted and finally have 0.8 bar and can see my fuel consumption going South rapidly while I enjoy the rush. If anyone else has problems fitting an MBC, PM me and I will send you pics. Now all I have to do is get the wonga together to have Bob Rawle work his magic. TD04L running at 0.8bar, anyone have any ideas or opinions on what I can expect from having my ECU re-flashed?

240-260bhp should be achievable depending on other mods.
