What's the difference between the 2 bar and 3 bar?

I'm thinking of getting the 3 bar, but what does it do better than the 2 bar?

When you have a tune your max boost pressure will more than likely be above 14.7 psi.
The 2 bar sensor will only read to 14.7 psi.
The 3 bar allows the computer to "see" the higher psi.
If your stock you cannot run a 3 bar sensor. The car will not run properly with it.

x2. These measurements are over and above atmospheric pressure, which is 14.7 psi or 1 bar. Hence the term 2 bar (atmospheric + 1), and 3 bar (atmospheric + 2).

Ah, so if I want the 3 bar, then I have to get the tune too.

Thanks Glock & SHO

So are there any power gains? smoother running? etc.....

I second this. I went from the 2bar with LME 4+ tune with a best E/T of 13.23 to the 3bar LME 4x tune and a best E/T of 12.75.

Thanks Guy's!

I'll get the tune, with the 3 bar.

I think you are about an hour from Torrie (Unleashed Tuning). You could pick up the 3bar in person and talk with da man

noidster · October 31, 2014, 05:39:21 PM

So what are the mods required/suggested to get any benefit out of a 3 bar.

SHOdded · October 31, 2014, 05:45:33 PM

Tune is the only requirement to allow the 3 bar to work correctly. For the tune, you should have new or newish spark plugs gapped at what the tuner wants (0.030 or 0.028). A cooler thermostat is also very beneficial for these higher performance tunes. That's about it!

Thanks SHO...

I'll look into what you said.

Been looking into the 3bar recently myself, I have a tune by torrie but he doesn't stock the sensor locally (Drat).. Also poppy you live in Ormond? I'm a mail carrier in Ormond, I think I may have seen you XD..

not to steal the thread here. I'll be in New Smyrna Beach from the 26th till the 3rd roughly. Any 1/4 mile tracks open down there? I'm getting my tune and parts installed next week and will probably be itching to see what kinda times I will finally run.

Closest here is OSW http://www.raceosw.com/dragway/ I've been meaning to go there on Saturday nights and funday Sunday but every time I get sat night off and Sunday off it rains out or inconvenient for me. If your looking for a mixed car meet/show there's one every Thursday night around 9:30-10pm in Daytona Beach behind the Steak N Shake / Burlington parking lot @ 1000 west international blvd I go there every week just because the honda's, mustangs and chargers keep trying with me XD
