This has probably been covered before but I was unable to locate the solution (search facility down).

I purchased a boost gauge today (mechanical) which come with wires (presumably for backlight) and rubber pipe.

Trouble is I cant figure out where exactly the pipe is supposed to go...was trying to work off BIG500 guide which is v helpful:

...but the pics suggest that the pipe should be fitted after the stock re-circulating dump valve with a T-piece...trouble is I have a HKS SSQV on mine so cant figure out whether to fit the pipe before or after the HKS SSQV and whether I need a t-piece.

Also will most car parts shops sell the T-piece if I need it?

All help appreciated.

Just been on Chiark's website which was v helpful...

Now its working...but the needle don't seem to move much over zero. The gauge is read by 'bar' and I'm not too familar with the psi to bar conversion. I know the car should peak at 17.4psi but have know idea how this converts into 'bar' or what gear this should be acheived in?

someone dug out a bar conversion chart...will look for ya!

bar/psi conversion table

Cheers Weava.

Me thinks the psi is better to read than bar. O well, i guess i will just have to get used to it

no pobs mate - someone dug it out for me when i had a similar question.

merely returning the favour:D !

i also prefer the psi as is clearer, but as you say you will get used to it.

Cheers,

Weava
