turbo gauge idle reading??

[keithiesbig1]

Alright,

Just wondering what reading use get on idle? I'm currently 0.7-0.8 bar under 0.......

I'm thinking I either have a vacuum leak or dodgy sensor

 

[Murray]

What reading do you think you should be getting??

 

[keithiesbig1]

No idea lol just fitted the sensor for the gauge so this is the first run/reading I have and just wanted to compare

 

[jesse888]

Sounds about right to me?

 

[keithiesbig1]

Cool, didn't get informed.what boost I was running when it got built so had no comparison figure, means I have scope as it's only 0.5 bar boost at moment

 

[jesse888]

What engines that on? I'm aiming for 0.5bar with my build

 

[keithiesbig1]

Stock B16a2 was dyno'd at 270bhp but going to get a run on a dyno dynamics which is proven to be accurate and get a remap too

 

[jesse888]

Cool! Mines on a b16b! Be good to see how both engines handle 7psi and what power they make. Although I'm wanting to limit mine to 270hp or traction and reliability.

 

[keithiesbig1]

Traction isn't an issue if it's setup properly and BONE dry

The other keith has 300bhp and 300ft-lbs and in the dry it's fine really, but he got boost set per gear so that might be why

I might try increasing a bit see how it runs

 

[jesse888]

I've got a 4.7fd in an s4c box. So shorter gearing than stock, I am expecting it to be manageable

Thats fine Keith, on idle you will be drawing a vacuum that reading is correct.

 

[sambo711]

Yeah man, as wishy says on idle it's drawing a vacuum so that sound about right!

 

[keithiesbig1]

Cool just thought it might have been too much but all good

As above its not boost you're seeing its vacuum - as you drive off you should see it go down and then back up again as vacuum swaps to boost.

Some gauges show vacuum to save confusion.
