Best Guages / Air Fuel Mgt.?
I am in the process of building a S/C setup on my 4th gen and I need to know what are the most important guages to have as to properly monitor things like fp, EGT, Boost and a/f. Those wideband o2 af guages are to expensive so the a/f guage is out of the question. I only have a pillar to hold 2 guages so which should I get? It seems that I would really need all 3. I will be running a vac/boost port FMU with a 6:1 or 8:1 disc and a 255lph pump, but I would eventually like to fine tune the mixture with a fields or apexi afc. Anyone know good info/pricing on either of these? Also as a side note is it always necessary to run some type of bov with a 7-9 psi s/c setup? Thanks in advance, I just want to do this right the first time.

But most of the stuff you listed isn't really necessary using the 'standard' SC kit from Stillen with 6-7 psi...

I was hoping someone with some experience with s/c and guages would give some opinions on which guages they felt were most important.
I am running a powerdyne s/c with a custom mounting plate so everything is being done by myself. I can't justify spending $3600
for a noisy V2 when I buy direct and can do the work myself for ~$2300 sans bov. I will be running approximately 8 psi so I think just a FMU would be sufficient but if I could get some info on a good AFC I would definitely consider it. Thanks.

I'm running the Fields Fuel Controller(http://www.field-net.co.jp/english/) along with EGT, boost, fuel pressure and trans temp guages.

You should go with a BOV... don't want to mess up your SC, right?

Since you're willing to hold only two gauges, get boost and EGT.

In the Stillen kit, there's a Bosch recirculation valve. It reroutes boosted air (let out because of a closed throttle plate) back into the intake. Since it doesn't let out into the atmosphere, it's fairly quiet.
Do a search on reading plugs. There's plenty of useful info.

For boosted cars generally EGT, boost, fuel pressure are the gauges to get. This company www.westach.com sells dual channel gauges so you could have EGT/boost on the same gauge.
