i recently founf out my clutch fan wasnt kicking on properly and helped my car to overheat.

my one had the original 1990 rb20 clutch fan on it and was replaced with a fan from a 1989 model. blades are definately differnt as i had to trim them to get them to fit under the cooler piping, whereas my original one did not have to be trimmed.

now my car sounds like those old falcons. fan is kicking on a lot but it sounds a bit stupid at times, but has fixed my overheating problem.

now my question is: do different fan blades make different noises. im talking in louder and quieter. i like the fact that the clutch fan i have now is working properly but the blades are just too dam noisy. my fan that i took off had evenly distributed blades whereas the one i have on it now has different looking ones and they are not distributed around the centre evenly. its just the way it was made.. if you guys understand that.

"irregularly placed cooling fan blades bring new quiteness"

thats a quote from Nissan marketing material.

i know exactly what you mean, long story short that type of blade should work better and be more quiet, then the even spaced design.

how many blades 7 or 9 on the fan you have?

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
