Which electronic boost controller?

[mrroverrover]

Is this any good? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=43120&item=7912267103&rd=1&ssPageName=WDVW

I'm thinking of a purchase but really don't know a great deal about these things, mucho advice needed!!!! :D

Yep looks good, although if you want something that works just as well, isn't quite so flashy, but a good bit cheaper, have a look at the Greddy Profec B

Thats the one I have and i like it.

My favourite has to be the GReddy Profec E-01, all singing and dancing.
For value for money and ease of use, the Blitz sbc or dsbc depending on boost levels.

What about these?

I've used the same style as number 1 on a Discovery Diesel and it was fine. Cost £17.00 inc. postage IIRC. I've heard other people say they are fine too. Definately the 2nd most economical way to increase boost and it's better than washers as it keeps the wastegate closed until the desired boost is reached. The more complicated unit, number 4, looks like it will be 2 controllers linked together. The second one being used to fine-tune the first I guess.

You can't write things like that without telling us from whom?

I got in on Ebay (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=7906659965&ssPageName=STRK:MEWN:IT)

I imagine an air-hose supplier can supply the bits for peanuts.

i like the look of that. cheap as chips (and im not ****d about electronic gubbins or adjusting in-car), and i dont want to adjust via washers..

i havent upgraded the HG yet so i wont be able to boost very high, but a couple more PSI from stock might be nice :)

are they easy to fit?

You need to install it to replace the existing hose between the compressor outlet and the wastegate. Not too difficult. I'm going to experiment to find an easy and *safe* way to get a starting boost level if Ian sends me his.

[Dillinger]

ive just ordered one of those cheap-ass MBC doobries. as for a simple safe starting point, is it not just a case of setting it wide open as if its not even there and progressively tightening it? (dons dunces cap in preperation for 'IDIOT' replies.. ;) )

[Lofty]

Yes, that should work.

Only point to note is that Ian said that his overboosted even when the screw was backed right out. This suggests that the spring in some units may be too firm for the pressure we are looking to achieve.

So just be careful first time out. If you have the screw backed out and it still boosts past your normal limit then you may have a problem.

[Dillinger]

ah yes that would be a problem.. i'll look out for that.
and since ive only got a stock gauge it'll probably be hitting the top and i'll have no idea what the actual boost is. (not that i have any intention of going above 8 while i have a stock HG)

maybe you can dismantle it and put a softer spring in? either way, its no great loss if its no good. ;)

Yeah they are very simple things. There is an air-hose supply place in Colchester and if I ever get to test Ian's valve and this proves to be the problem I was intending to pop along and see what stuff they keep. I'm guessing that they probably keep boxes of calibrated springs for pressure releif valves and such. Let us know how you get on.

Which did you go for in the end........if none I might be selling mine.
