hi everyone! i just bought my first subaru classic 98, theres a boost gauge on the car and seems to be all wired up but is not working? ive read on this site about the fitting of boost gauges and it talks about a sender unit which i cant find under the bonnent. also cud someone tell me the purpose of the boost as am a novice to the subaru workings great site thanks

am also after a backing for behind my bumper? and a ariel with coxcil cable up to the stereo if any one would have ant for sale thank you

 

boost makes the car go faster. Have a read.

There should be a vacuum hose going from somewhere on the inlet manifold to your boost gauge - if you can see or get access to see the back of the gauge, check if there is a small hose (about 8mm in diameter and usually black or blue, but sometimes smaller and clear like mine) going to the back of it. If there is, make not of size and colour, then go open bonnet and look for the same hose coming through the firewall to the engine bay.

If you can identify it, follow it, make sure it terminates snugly on the inlet manifold and has no splits or cracks.

If there is no hose on the back of the boost gauge then it won't get a reading.

 

Thanks very much, checked it all out and the boost pipe was crimped closed at the firewall, boost goin now, I don't mean to be a div, but wht am I looking at?? Lol it's ideling at 14 and rising to bout 7, whts dis telling me ?? Lol

 

What does it go up to when you put your foot down while driving ??

 

Avin tried it mate ave the Interior pulled out at the min

 

You need to get it on the road and check the gauge while your driving.
The gauge measures how much boost your making, your gauge reads in PSI by the sound of it. If your car is pretty much standard then a reading of +14 would be about right.
Get the car out, check the reading and then post your find.

 

Thanks for your help mate, I'll do tht and post it up, so the boost is from the turbo rite??

 

well yes the turbo is what makes the 'boost'. Read the link I posted above but basically it compresses the air that goes to the inlet manifold. Compressed air = more oxygen per unit of volume (going into the cylinders, via the inlet manifold) = more fuel (able to be injected to match the bigger mass of air) = more power.

 

And for a support bar for the bumper, try e-bay, or awesomeimports.
