Idle Valve And Aac Valve

Well the AAC/idle control valve controls engine speed (by a an amount) with a PWM modulated inlet leak.

That small amount of adjustment is required to give you a stable idle even though there is load appearing and dissapearing.

A/C, h.beams, stereo etc etc, as well as catching the motors decel after depressing the clutch.

AFAIC, if you don't use one, your idle will fluctuate with engine load at idle. That idle RPM in question will need to be set quiet high too, to prevent stalling when above said "motor decel, clutch press" occurs.

Interestingly, i guess a race car wouldn't need one. Could you let us know, why your thinking you don't need one?

My enginneer don't wants to leave it... as the A/C... as my ABS :down::(:ermm:

And for steering he will use electric pump not hydraulic (from a toyota car).

Also he don't wants to put the 044 pumps into the boot...

No idle.. no a/c.. no abs.. and two 044 in my ears!! All theese for every day car?? ;):( :(

I want my car for drag races but also for everyday use... so I think that I need the AAC! But how to obligate him to do it... he wants to make my car for race use only. :wave:

Will be an interesting daily street car with 600hp, no anti lock, no air con, and two 044's mounted in the engine bay :)

Its your car man, your mechanic should be making your dreams and wishs come true, not to have you fund his garage's demo car :D

Nothing anyone here can do about YOUR car and YOUR money ;)

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.

      iPad gauge cluster

      First thought is to use a ram mount (to hold the ipad) + windscreen suction mount. The arms on the ram mount can be as long as you like, should be able to position the ipad pretty well with that setup.
