- 13 MX-5
I washed my car and put my wing back on.
Car off: 0 vac.
Idle: 20-22 vac.
Decelerating in gear: 22-26ish vac (to answer you: yes, that's normal)
full boost SHOULD be somewhere close to 6-6.5psi, but i have heard of some getting as low as 4. Pretty sure that's not normal though.
get in third gear, about 35-40mph, put the gas on the floor. The needle should jump VERY quickly to 0vac, then pause and start building boost. If it jumps to 3vac and pauses i should think you've got an issue. There's one quick test. But it should def. be 0 vac when turned off.
If you call the company that made the gauge, i would think that they will either re-calibrate it or replace it, no questions asked. try that if you think it's off. But check the line for any bends, kinks, or leaks. I super-glued the hose connection into the T and into the guage so it was sealed 100%; and my line is hard plastic/vinyl so it can't bend very easily (no kinks).
its broken if it reads anything other than zero while its off.
anyways today for my msp....i looked at it as i drove off to work in my dads sti.
Thinking of getting rid of it after driving the sti?
not at all, i love my msp and all its rareness. plus i havent even come close to what id like to achieve with it. whenever this engine blows (im suprised its made it this far) ill get a forged motor and should finally be really happy w/the car.
raced my stock MSP against my friend's stock 07 impraza and won =)
no props unless it was a wrx. beating a 2.5rs is nothing.
looked at my msp again as i left for work in the sti...again(lol2) dont worry im not losing interest in the msp or anything. one of my coworkers wanted a ride in it but we didnt have the chance after work yesterday so i took it to work again today. needless to say hes changed his mind from getting a tacoma to seriously thinking about a wrx. he has about 18k to spend, what do ya think? im certain sure he could find a pretty good 04-05 or a really low mileage bug eye'd for that price.
