even my Defi was off by 2-3 psi ...

 

just found this article on http://editorial.autos.msn.com/artic...umentid=643806 if u want to check it out but heres the main part of the article that should satisfy this thread lol


The Ralliart uses a smaller turbo than the unit that pressurizes the Evo. The max boost pressure really tells the tale, with the Ralliart seeing 13.3 psi and the Evo pumping 22.4 psi when the hammer drops. Consequentially, the Evo generates 291 horsepower compared to the Ralliart, which is rated at 237 horsepower and 253 lb-ft of torque. The Ralliart sports a blocky, plateau-like torque curve, with its peak 253 lb-ft online from 2500 to 4750 rpm.

double post

 

That's not why you're "getting jumped on", it's because 1. you installed the gauge incorrectly, 2. you installed an already poor quality gauge incorrectly and 3. you think that allows you to dispute datalogs.

 

I will install a boost gauge today...I'm really being patient with this. I don't need a boost gauge. I'm not increasing the boost. LOL.

Also, i'll convert the reading from bar to psi for everyone. Someone might think 1.4 bar is 1.4 psi... :hammer:

 

^ty

 

if it was incorrect the boost gauge wouldn't work> have u worked on a RA? Have u actually looked at the vacuum lines? So u think the the gauge should of been hooked up by the vacumm line goin into the intake?

 

If it was installed incorrectly, it could still work but give you an inaccurate reading. An easy place to hook up the gauge is at the vacuum line that goes to the BPV.

 

lancerdave86: I think no one's trying to go against you, just for kicks. Yes, you install a boost gauge and it reads just that. But if there's figures coming from more reliable sources, i don't see why any one would not believe it. Plus, its just seriously abnormal for a ralliart lancer to run on 9psi of boost.

 

HAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHA HAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHA HAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHA HAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHA HAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHA AHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHA HAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAH HAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHA HAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHA HAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHA HAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHA HAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHAAHHAHAHAHAHAHA AHHAHAHAHAHAHAAH

hook it up to a line on the IM.

 

LMFAO this guy is bold!

1) Use the search pal

2) You need to get a pressure source from the intake manifold. Diverter or FPR lines....


3)

 

yea thats how it was first hooked up and it wasnt providing us with a reading

 

Then you hooked it up wrong twice.

Hook it up to the vac line going to the intake manifold right by the oil dip stick.

From the photos you posted earlier, it looks like you T'd it into the boost control lines which is 100% incorrect and will not only be inaccurate, it could also mess with the boost control.

 

Hello, Today after work I wanted to put an end to this 9psi assumption.

It was a beautiful day today over 60 degrees F. When I get home and try to find some vacuum line. I found some, but it was long enough so I just used another T and capped one end and extended it.

Starting off I Tee'd from the stock blow off valve. Since I don't plan on keeping this boost gauge installed. I just pulled the hose from the engine bay to right corner of the hood and through my window!!!

I hook up the line to a mechanical Greddy boost gauge. You know the one that's through the driver's side window. I tape that crap down in between the cluster.

Problem, this gauge doesn't glow like the glow shift one. Since I'm not keeping this on the car, I did not want to wire the gauge. It's 5:30pm and its dark outside. I figured this is stupid...I'm not going to bang out my car. So I do a quick 2nd gear pull down my street. My street is a 2 mile stretch til the next street light.

I recorded a short video clip and uploaded on photobucket on the link below.

The video is pretty dark, but the results are it spikes about 1.3bar or
(18.85 -19.11 psi) and then it quickly tapers down. I just times 1.3bar with 14.5psi atmospheric pressure and 14.7 to get this range.

Install time: 5minutes. The car is back to stock again!

 

Here is the picture of that extra Tee. The blue thing is the cap.
Plus pictures of my dirty little Ralliart.
Lastly, the hose back to stock.

I did a pull from like 2k to get the boost spike. Then let off around 4k and stepped on it again. After 4k the boost gauge doesn't go past 1 bar (14.5 psi).
