Hiclone (anyone using them?)

Hi

I'm looking to increase the performance of my 200tdi 110 (1990 with a later engine) :twisted: , I have read lots of good things about these things, but haven't spoken to anyone using them.

Are any of you using them and if so what do you think of them (are they worth £79.95) :?:

Thanks

James

P.S. I you dont rate the Hiclones, can you suggest any other ways to increase performance on a budget and without installing a V8 (someone would say it so i thought I would get it in first). :lol:

muddyweb:
First off... I don't rate them at all... I have seen no independant engineering data to support the claims from the manufacturer... and there is plenty of data to suggest that they don't

In terms of increasing the performance of a Tdi engine......   well....

To begin with, it is a fairly agricultural bit of kit, so you can't expect miracles.  A good service and clean will often provide a bit of a boost.

The "cheap" ways to improve performance usually involve changing the boost pressure and fuelling, fiddling with the wastegate and EGR valves and other such things.

Whilst these will have an effect, you need to be very careful.  There are plenty of ways you can damage a Tdi by over-adjusting things without some proper care and a whollistic view of the engine.

The killjoy answer is that there is no cheap way to do it.... because all too often the cost of engine damage makes it all very expensive :-(

Bob696:
I have a set fitted to my 93' 200Tdi and the difference is noticable (at least on my engine)

She accelerates smoother through the rev band (the turbo appears to kick in earlier) and I am getting an extra 2-3 mpg. Comfortable motorway crusing speed has upped by about 5mph. It is nothing remarkable and you will have to decide yourself if it would be worth the £80.

philbert:
increased performance . the boost can be turned up to 15psi with no ill effect.the pump can be tweaked for a little more go.bigger intercooler is the way to go .if you cant afford a new one then tour the breakers for one out a jap motor and make it fit.
