Hey guys,

Just a simple little question... gotta HKS 25/40 being installed on my R33 and just contemplating the idea of the screamer pipe...

I had one a while back also on an R33 and sounded wicked under full throttle but really ghey at half throttle.. like an exhaust leak... Just wondering since a HKS 25-40 is obviously laggier than a stock r33 turbo will the crappy exhaust leak noise be minimised at half throttle as it wouldnt spool up as easy/earler as the HKS turbo..??

Thanks!

they sounds pretty lame on any internal gate turbo in my experience. and will always be leaking some gas as it's nigh on impossible to really seal one up as the turbo oulet flange is not designed for that.

Just so you realise the screamer will be VERY loud. I had one for a while but i got rid of it as it was just too loud for me and i love things ear piercingly loud. I once overtook a car with both windows down and the sound rebounding into the car was crazy loud.

You guys probably just havnt heard many screamers done PROPERLY on internal gate turbos.. mine sounded ***** wicked on my old 33 with a 3inch & no cats, 12psi, power fc etc. Only time it sounded ghey was at half thottle.. sounded like a bit of a tractor..

But im thinking with an aftermarket turbo like a HKS 2540 the gate doesnt open as early/easy as it does on a standard turbo so i shouldnt hear much of that tractor noise...

can anyone confirm this?

I think we have just heard to many bad examples of home made screamers on stock R33's etc running near stock boost on standard turbos..

We'll see how it sounds on mine running 16psi on the 2540, plus im now running GTR rods so ill be getting more RPM too :)

an extra 500rpm still makes me happy :)

oh well, we'll see how it sounds on mine. As long as i dont get the tractor noise at half throttle ill be happy, cos the rest sounds good.

Hmm... I'm a wierdo... my BOV is plummed back with a bigger pipe to make less sound... My 3" exhuast isnt the quietest but it sounds like a fart can on an excel when idling and mid revs is just a drone.... sounds fugn aces with WOT.... like an old 70's turbo F1 car only way not...

AND...

I f..g love it.

trust me... any extra noise you get in your car will only serve to shit you in the long term.... specially if you cruise any distance.... unless you can tune it out....

Oh yea... I don't get a second look from police unless their in the mood to make trouble for anyone in particular...

      Cas issue

      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.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      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.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
