Perdana v6 : Road to 300whp.... and beyond

[RENESIS VIII]

air path
intake > maf > turbo(cold) > (bov) > throttle body > bang bang > (waste) > turbo(hot) > fart fart

edit:ehh wait.... am dumb @x@

damned....
intake > maf > turbo(cold) > bling bling infront > (bov) > throttle body > bang bang > (waste) > turbo(hot) > fart fart

The MAF and BOV is optional though. I've seen some turbo setup without MAF at all. Directly taking in air from the compressor itself.

As for BOV, I think that is optional. Stock engines mostly uses a bypass valve to reroute the air before the turbo itself.

maf.... they should ahve the maf or map sensor.... really depends on the ecu....

bov is usually installed... (btw its installed, after the turbo) otherwise you will have that wupwupwup fluttering sounds (some say this isnt a good practice)
imagine a senario where you suddenly release the accelerator when on boost, the butterfly valve is prettymuch closed and the air has to go somewhere. If there is no bov to release it its got one other way out, the way it came in. The built up preassure would force the air back out the turboopposing the compressor's spin (wont spin backwardslah) compressor surge isnt great @x@

The built up preassure would force the air back out the turbo basically trying to get the blades to spin backwards opposing the compressor's spin (probably wont spin backwardslah) compressor surge isnt great @x@

I mean reroute the charged air to before the turbo itself. I left out the word 'to' earlier. I understand how BOV or by pass valve works. They are normally at the piping after the intercooler and before the throttle.

My BOV before intercooler woh!

Dynojet. "Normally"means normal setup/similar setup to my mods??

Bigger turbo, would 20g sufficient upgrade? bigger turbo means need to have supporting mod internal parts.?. :hmmmm::hmmmm:

Yes, that was what I meant. Because that was the amount I got
20G is definitely sufficient to hit 300whp easier with lesser boost. If you want to remain stock turbo, you will need supporting mods to bring it closer to the target such as performance cams to name a few.

 

[Shinjite]

curious to know, will a TD05 20g reach 300hp?

300BHP? Definitely

Eh? Possible to set it like that? Then that means the air that has been cooled by the intercooler will travel backwards to the BOV when the throttle is closed?

 

[vr2turbo]

BOV is to release the pressure when lift off throttle.....

asalkan post turbo and before throttle can dah hehe

 

[RENESIS VIII]

asalkan post turbo and before throttle can dah hehe

Then what about those compressed air between the throttle and past the intercooler? They'll probably go backwards into the intercooler again because the pressure before the intercooler is lower after BOV releases the air?

Good to know 20g can achieve. But is it possible 20g with stock internals?

If stock setup unable to achieve that, everything must upgrade once the stock parts is changed

Looks like need to go stage 2, what I have in mind:
-20g turbo
-Oversize piston (1jz/Pajero)
-PnP
-Lighten cam/crank/pulley
-Upgrade rod bearings
-Upgrade injectors n fuel rail

Gbox.. Hopefully clutch can withstand..

Stage 2 unable to drive it daily :sleep:

And kapischssss sound don't forget..Or chu chu chu

i dont think they would go backwards, the BOV will equalize those pressure after turbo > throttle. Those connection are seal and connected in single/serial route.

20G to hit 300whp with stock internals is possible.
Clutch better to upgrade, at least an Exedy 4 puck like what I am using now. Not that stiff so jams still okay
Injectors and rails don't need to upgrade. Can withstand 300whp. But if you want to upgrade, later EVO ones will do at 560cc. You absolutely don't need any higher.

actually charged air pre & post intercooler, almost the same je. its a slightly dif density dif due to the temps. and yeah ur right, it will flow backwards if the bov is located pre intake.
if anything.. maybe the response might be slightly affected in event you blip the throttle, i duno

omai i see lots of manyak mahal bits there......

20g with stock internal is it reliable? or supporting mod needed? I suppose boost could maintain around 1.3?

usually i heard twin plate clutch is better, not sure about clutch though. I'll see the duty cycle for injector ,if there is any need to change, i'll change

I actually draw this using Paint before few years ago to explain about turbo engine to my friend.

Simple and easy.. but you tell 0 knowledge people, can say that you are playing a piano in front of a cow...

Well, because some of my friends ask me what is turbo engine. So, I draw this diagram to explain to them. But first, I need to tell them about how an engine produce power. By the combustion of air fuel mixture. If not, how to explain about the extra intake air provided by the turbo.

Many will tell me why don't I go for engineering to do something related to car. I said, everyone in forum knows all these and many of them are not even in automotive industry.
