not too sure what is causing it, but if I have my A/C on and I'm at full throttle (or pretty close to it) and the car shifts, it goes PFFT!

is there a pressure bleed valve on the compressor that kicks in?

right now I sound like a ricer

 

seriously, you dont know what it is??? u know everything................

lol it does kinda sound like a bov, actually more like a belt squeel for 1 sec


if ur ac is on, and ur at WOT, the compressor turns off, for more power

so when you shift it kicks iback on really hard, thats what it is, i do it all the time.

but seems like it would be really hard on the ac clutch, it kicks in at like 5k rpm, cant be good for it.


wow how did i know that, idk i think i read it in the FSM

 

Dude you should be thinking of a way to amplify that sweet sound...

BTW My friends old Sentre SE-R made a supercharger sound when his engine would wined down, it turned out to be the alternator was going bad. It had a fairly high pitched sound which kinda sounds like a BOV. Not sure, it's your car you know more then I about where the noise is coming from.

 

I'm at work with no FSM handy to check if the compressor has a pressure relief valve.
BTW I did know about the compressor cut out, it's pretty common on most cars. But I've never heard the PFFT sound on any of my other ones.
I'm just worried about losing R12. I don't want to put R134a in my car.

 

im pretty sure its just the compressor clutch kicking in at high rpm....






but then agian wtf do i know???

 

Mine did the same exact thing before I got the UDP.

I wasn't sure if I was loosing r12 or not, so I would always hit the AC button off when I thought I was going to rev it hard. My AC still blows cold, but I haven't had that problem since I put on the UDP. I guess you need to get one

 

hmm, myne make the sound and i have UDP

 

It's probably pissed off at you for buying a 4th gen..

 

I know I need one.
give me yours

 

the Ford gen is on ebay as we speak.

 

That will be $4200* and I will throw in the Maxima for free.










*does not include shipping to Chicago

 

4 figures is too steep for IA

 

sheesh for that price it should include shipping.

 

The engine was installed by Jeff92SE -- that right there makes it like gold. I am practically giving it away...

 

if jeff installed it you should give it away

 

Ohhhhhh BUUUURRRNNNNN!

 

Mine did that too

Fidanza/UDP/etc


Kinda funny considering the AC should be off at WOT. I never bothered to check it out, I blame the ricer in me.

 

I'll bet you were trying to figure out how to do it more often

 

my stealth sounds like it has a turbo... but it doesnt.....i dont know if there was a bad weld on the exhaust, but it whistles VERY loud at 3000+ RPM..... and when i let off the gas, it also sound like i have a BOV..... but i dont..... i really wanna know what is causing that..

 

Vans, go buy a chevy. that way you can afford to keep fixing it

 

dude there isnt oe thing right on my car.. the ECU is going bad... i am running on 5 CYlinders...(should have fixed the maxima), passenger regulator is bad....slave cylinder is not holding pressure...... ohh and i just got into an accident on my birthday......i need a front bumper cover, a eice of metal behind that... a fender, a hood, and headlight.....


it will all eventually get fixed......it is a good thing i work at a mitsubishi dealership... HA HA
