Re: HFS-4 intro, application for your engine...
 

Is the physical setup with the HSF-4 the same as the HSF-3 say in my 2001 audi s4?

Re: HFS-4 intro, application for your engine...
 

yes it is.

What do you have in mind on how the system is set up?

Re: HFS-4 intro, application for your engine...
 

That's all I needed to know. Thanks.

Re: HFS-4 intro, application for your engine...
 

In that case, setting the system up is a lot easier.

There are two options on the filter front.
1. We manufacture a high pressure 130 micron inline filter (Picture below)

2. It is poossible to supply a jets with a 25micro internal filter. But it is only available on a 0.3mm jet. flowing about 100cc/min. We can put the same filter in a larger jet but the filter and clog up within a few months unless you put another 30 micron between the tank and pump. (pictiure below 2/3)

3. The HFS-4 comes with an in-tank 112 micron filter (picture 4/5)

I think I will stick to pre-pump filters most likely the intank that comes with the HFS-4 and then an additional 30 micron.

Also can you comment on Since there is no flow data for the injectors I will be using (rs4) how can I calculate nozzle size?

Thanks again!

Re: HFS-4 Q&A, application for your engine...
 

If you don't have any dtat of the flow capacity of the fuel injector, estimating the flow by power. I normally work on 500cc per 100bhp and 450cc/100bhp for di engines.

Thanks Richard.

How easy is it to fit to the R56 and are there any generic instructions etc for newbies like me to try and get this fitted.

I have read the one thread about the HFS-3 install and believe there were issues with jet size. Would I get correct jet size supplied if I advised what car it is going in when ordering?

And lastly, due to the carbon build up and high IAT's on the R56 turbo mini I am hoping such install would alleviate this. Would I be correct in thinking that fitment would then need that the usual pre-requiistes for the mini like a better FMIC and OCC fitment would no longer be necessary with an aquamist install or would they compliment such an install?

Sorry for all the questions !!!

Carbon issue is common on all di application. It looks like the Di gasoline is become a diesel soon, inheriting the carbon problem.

The HFS-4 has two extra inputs dedicated for the di engines. Monitoring fuel rail pressure and manifold pressure.

Post timing clashed, will reply as soon as I can. It requires more than two lines.

Thanks Richard.

Look forward to your response as I believe there are a few Mini owners already jumping on this and have posted a link to here on a couple of the mini forums for wider exposure.
