Understanding gauges for superchargers and why you need them

[SUMOTOY]

That's a good point too. Don't know the dimensions but maybe replace the clock w/ that Greddy unit... I guess somewhere near the direct line of view is best but not much playroom...

The clock area will probably work. In my install above, I can only say that the emergency flasher install with a 1.5in guage was *really* tight (moved the flasher switch to the left of the rear heater switch). I had to pull the clock when I did my install, and there is a lot of room there to use.

Direct line of view is pretty critical, especially in boost applications. Too far from straight ahead, and you have to search to reference it. The other spot I considered seriously would be the 2 switch blanks to the left of the steering wheel, underneath the DS vents. There's some decent room to be had there, but I suspect recessing it into that dash curve won't be easy.

Scott, remember your dash is different than mine and lots of others because it is a 94.

Darn you OBDII guys agin. The clock port appears to still be the best spot. I copied this from lx450landcruiser ROTW. It certainly appears you have a lot of room at the clock, and I suspect you could move the vent over 1, and modify the clock trim to frame the screen, and have this really close to line of site Ken.

Good thought. The picture really helps

For a very educational webpage on superchargers and gauges, etc. check out gadgetonline.com. This page is based on 3rd generation 4Runners but you will learn alot.

That was very useful. The link to gauges is a little lower so I will post it here:

So, I am looking a15 psi Boost gauges. Some go 0 to 15 and some go 30 to 0 to 15.

Ken,

The first link is for a combination boost / vacuum gauge, and personnally, I feel it is a more functional gauge than the boost only. You can use the vacuum readings to monitor engine conditions & gas mileage.

On the previous posts, I would just purchase standad gauges, and use your OBDII scanner for diagnostics. rather than constant monitoring. Save your money, since you are buying all the beverages at CM07, and your scanner is not a real time unit.

Thanks Joe, I am already on the plan for gauges. I bought an autoxray 4000 OBD II scanner yesterday (Me likes) and have already ordered my temp gauge and 2 gauge pod. Just trying to decid on the vacuum/Boost. I take it from your post there are two needles and this is a dual purpose gauge. I couldn't tell that.

Thanks a bunch

Ken

BTW - it was Christo's idea for the beer, let him buy it.

LBA: Ken, the VDO vision series pointerd are really easy to read at night, since the pointer itself is lit, and the white numbers are also lit from behind. I find that VDO guage to be very accurate.

HBA: Vaccuum/boost guages tend to be less accurate than strictly a vaccuum or strictly a boost guage. The 0-15psi 15010 guage will give you a really accurate reading of boost pressures. In turbo applications where vacuum leaks become overboost leaks (blows up turbos), having the vacuum is a good indicator of leaks. That's why they are a good idea in a turbocharger application. On a supercharger, it blows max psi based on rpm, bad vacuum hoses won't kill it. The V/B guage willl be much more entertaining as it is always hovering, the boost guage only wakes up when the SC is working.

Thought I would post up what I have ordered and what I am doing


I am going with the Autometer Vac/Boost gauge

Auto Meter Z-Series 2-1/16" Mechanical Boost / Vacuum Gauge 30 In.Hg / 20 PSI Gauge. A48-2601​

I am going with the ISSPRO #R5650 Water Temp gauge (Same as Cdan):

I also ordered the Autometer #20112 "fits 1994-2001 Acura Integra". Double pod in Tan color. This installs on the pillar to the left of the windsheild. Now I have to find paint to match the dash.

For the OBDII stuff. I bought the Autoxray 4000 on clearance at Checker yesterday for $220. It works great and lets me monitor the real time data. I liked this over the Actron and a few others because of the size of the screen. So I can plug this in when I want to be able to monitor other items. I will have this plugged in when I get the TRD and next time I tow up Eisenhower tunnel.
