Boost gauge install...


"Remove the cover off the white wiring connect box in the corner of the firewall area under the cowling" "Remove the rubber blanking plug as show in figure 8"

ok i cant even find this... there is nothing white by my firewall... please help

 

Huh?

Not entirely sure what those instructions are trying to help you do. The only thing you need to remove by your firewall is a round body plug that leads into the driver's footwell to route your vac line, and it's black if I remember.

 

haha its ok, i figured it out

i said the same thing with the instructions... huh?

and the gauge is in and works like a charm... Im hitting 15psi and holding that... thats where it should be for a 180 chipped right?

 

pretty much, so get that boost up!!!

 

i can get it up to like 20psi max right?

 

20, 22, 24 whatever

 

If you get an MBC... you should be able to turn it right up. I have the Boost Machine from Modshack and it works great. Others prefer other ones. Either way, that should be all you need to get that thing moving a little faster.

 

Cincy you cant tell him "whatever" he will try to run 30psi on his k04....just playing kid you should be ok at 24max, I have seen some 1.8t's that crank their wastgate and hit 27psi, I cant even imagine how much heat that is pushing out lol.

 

I had mine up at 25psi when I first installed my boost machine but I turned it down because it actually felt like I lost power.

I believe I read on here somewhere that the calculation goes like this:
1 Bar (14.7 psi) of boost = 100% HP increase.

However, you lose power based on heat and drivetrain loss too. I would imagine 14.7 psi was more accurately equal to 65% increase in power. Soemthing like that. but anyhow. That being said... going from 15 psi to 22.5 psi would be a 50% increase in power. (make sure you remember that the increase percentage is based on the engine's power without a turbo on it. So basically, if a 225 is getting 225 HP at 14.7 PSI... then it more than likely would mean that the Raw engine was putting out around 110-115 HPwithout any turbo or boost. so take that 110-115 psi and multiply that by the 50% increase from 15 to 22.5 and you have about 55 hp increase without factoring in heatsoak or drivetrain loss. factor those in and it's closer to 30hp.

This is just a logical viewpoint and calculation based on things ive heard on here. If this is dead wrong... please someone correct me and school me up because this is how I've been figuring power changes on my car.

 

Ummm i dunno all I see is numbers and percentages but it sounds good to me!!!
