Hi, What fuel pump would you use with the SC12 supercharger in a 1330?. I've got one of Ben's kits and looking at a facet fuel pump.
Interupter or solid state?
- 6.0 - 7.25psi & 25 gallon/hr
- 4.0 -7.0psi & 35 gallon/hr
- 6.0- 7.25psi &40 gallon per hour

Or would any of these be OK?

Doesn't matter about supercharger, it's about carby. What Carby? If an Su, HIF then say is good 3psi.

The little facets are fine, in fact i had TOO much fuel going in when my jetting was wrong so a little 3psi pump is fine to keep up with demand even with a 'charger.

The carb is a HIF44 SU. I was also planning to get one of those filter king filter/regulators

I'm running a Facet solid state fuel pump, that runs to 3psi. Pumps plenty of fuel. Long story short, my car was flooding due to vibration of the HIF44 and it made 74hp ATWs too. But due to flooding and igntion could not rev any higher than just below 5000rpm. So really a normal fuel pump will do the job I think. Although I wonder what sop much fuel is doing to the charger.... :? Should be fine.

However I'm not sure of a mechanical one would keep up?? But obviously you'll be using electric. I'd say the 4 -7psi would be good with a regulator.

I have the same set up, though only on an 1100, but fuel pressure is fine with a standard facet pump. I was going to upgrade to a high pressure pump with regulator, but when in getting tuned, was told there was no need! So the money was spent elsewhere, like a decent ignition system...

What I need to invest in. Nissan is good, better than Lucas but not that good.

:D
Yeah have been told by a guy I know that runs it on his ford 302 and his sigma turbo, it's a pretty sweet system...
Apparently start up is better, should idle like a new car and burn bright through the rev range!
Not cheap, but what performance product is, especially with brand names like MSD 8)

4 psi is too much for an SU carby and will always try flood itself.
Try running a lower pressure 2-3 psi but increase the fuel line size.
