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

The system comes with three jets: 0.8, 0.9 and 1mm and a tee-piece. It should cover all operating range (350cc/min to 900+cc/min) from a single 0.8mm to 0.9mm +1mm. We can always pack and label them before leaving the factory.

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

I'm new to this, but from what I've read on MINI forums, .6mm and .7mm jets seem to be the most common ones used. I'm still trying to figure out how the system works... so can I adjust the pressure (looking at your graph) for a larger nozzle so that it has the same flow as a smaller nozzle, or is the pressure regulated in such a way that I need to order more nozzles?

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

It is always better to have a smaller nozzle than reduce the pump pressure for running a larger nozzle.

GB are shipped form Aquamist or Howerton. Either of us can swap the jets over before despatch as long as you request it.

I plan on running direct port so I need 4 nozzles the same size how can I arrange this since I wont need a tee-piece and would like the 1-4 port instead

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

Well there we go :D I would like which ever jets come with the Howerton R56 kit.

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

You can order the DP components from Howerton as you are USA. I am sure something can be worked out.

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

There is one other useful addition unique to the HFS-4. It monitors the rail pressure pf the HSFP full time so that it compensate the meth flow between idle, cruise and full load.

Man, the more I read about this new kit the happier I am that I dind't have the money to buy one sooner, or else I would have gotten the HFS-3 and been bummed out when this one came out. :D

Can we talk about this cooling fan for a minute. I was looking at install instructions and check out wiring diagrams and what not, and can't figure out where it hooks up. Is it just a PC fan?

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

Do you have the wiring instructions for the Cobalt SS/TC?
