Do some of you use? I know boost for sure. I was just curious what other types you use for a blower application and why.

 

A fuel pressure gauge is mandatory. It's important to know that pressure increases with boost. Decreasing pressure means an insufficient fuel supply (pump is not capable) and could result in disastrous results.

BTW, you have e-mail.

 

Thanks Wille, I got it. So then I would assume thought someone makes a fuel pressure guage that is safe to use in the interior?

 

AutoMeter makes a full line of electric fuel pressure gauges. They're not cheap, but neither is supercharging!! Here's mine (upper center):

Willie, you almost have that Knight Rider thing going on in that dash. What's that digital display above the ERS emblem?

 

on my GN i use autometer phantom water temp, oil pressure, and volts- because they have dummy lights- then i use a boost guage- under the hood i have a rail mounted FP guage.

 

Yes, I've been told sitting in the driver's seat resembles an F15.

Here's a rundown of my gauges:

First, the analog fuel pressure and vacuum/boost gauges. Under these is a TPS non-linear bargraph that reads from 0 to 4.5 volts.

Custom fabbed digital gauge console under smoked plexiglas below center A/C register and behind an LED display panel. Left to right:

Voltmeter. Displays voltage to fuel pump. The voltage is adjustable with the **** to the left with Kenne Belle's Boost-a-Pump.
Tachometer. With memory recall. Great for recalling high rpm's after a 1/4-mile pass.
EGT (x10). Exhaust Gas Temp.
Trans Temp.


LED Display Panel. Left to right:

Port Solenoid - A poorman's open/closed loop indicator.
Converter Divert Solenoid - Want to stay emissions legal and I like to know when the air is being channeled to the converters.
TCC - Torque converter lockup indicator.
WOT - One pair of LEDs that flash when at wide open throttle, just for the fun of it.
P, 1, 2, TR - Old pic. These are now labeled P, S, TP, TS for coolant fans. Primary, Secondary, Transmission Primary, Transmission Secondary (two 7-inch fans behind a pair of smaller transmission heat exhangers.
H2O - One pair of LEDs: Alky injection armed (left) & injecting (right)
LL - Line Lock on.
LN - Launch rev limiter engaged.
WB - Wide-Band O2 sensor ready.

And under these LED's sits a 21-LED linear narrow band O2 voltage display. This was built and installed years before the first A/F ratio gauge was marketed.


Three digital air temperature gauges under smoked plexiglas, eliminating the ash tray:

Left: In custom airbox prior to supercharger.
Center: In air tract after supercharger but before intercoolers.
Right: In air tract after intercoolers but before throttle body.


Instrument Cluster:

30 LED Wide-Band A/F ratio bargraph.
Note the 6,000 rpm redline on a V8 tach! Also the supercharger rpms are shown on the tach from 4,000 to 6,000 rpms.

Note: All bargraph circuits were designed, tested and built by Tim Burgess, our EE guru and moderator of the Electronics Board.


I also have a bunch of switches on custom fabbed panels but that's another topic.

willie you have a really nice car and i like your gauge setup......but how on earth do you look at all of that when you get on it? all i need is a tach

 

I don't even watch my tach (auto)! When racing, I primarily watch my fuel pressure gauge and I see the WB LEDs out of the corner of my eye. Many of my gauges have high memory recall so I can always review those values afterwards.
