Kando Dynamics Turbo

[XRATED]

Is the EVO 10 ex manifold divided 1-3, 2-4 or 1-2, 3-4?

Cheers

If they're like the 4-9 the exhaust manifold they link the outer and the inner pairs of exhaust ports ie 1+4 aqnd 2+3 .

That way when the inline four cylinder goes through its 1-3-4-2 firing sequence it alternates between each side or outlet port of the exhaust manifold . The idea is that each cylinder vents into an area of low pressure because the last vented into the other side of the manifold and turbine housings scroll . This way more of the exhausting cylinders thermally excited exhaust energy (gas velocity) is screaming into the turbine blades .

Where you have a single outlet manifold and single passage or scroll turbine housing all cylinders vent into the common manifold/housing meaning the average pressure inside it is higher , because of this each venting cylinder is venting into an area of higher pressure and can't exert as much energy or gas velocity into the turbine blades because of the lesser pressure differential .

You can reduce the pressure in a single scroll system by increasing the size of the turbine housing but you lose turbine response by doing it .

Twin scroll systems allow you to use bigish A/R turbine housings without much of the turbine lag so they are a win at low to medium as well as higher engine revs .

Interestingly the Americans have come up with a torque number that they try not to exceed because if they do they bend connecting rods and break pistons - on std 4G63T engines anyway . I think its something like 400-420 ft/lbs they try to torque limit them too and go looking for cams revs and Hp numbers instead .

Personally I like the idea of those sorts of torque numbers at 3-3500 revs because it makes a Lancer with AWD and sort of short closish ratio gearing a slingshot off the line and they pull like buggery in every gear .

My 6 is mechanicaly std ATM but after the first time I chased a bike off at the lights and nearly ran over it I learnt not to do that .

A .

Um BTW , a correctly phased inline six cylinder twin scroll exhaust manifold links 123 and 456 . This is because an inline sixs firing order is 153624 and to alternate evenly between exhaust events thats how the manifold has to be . Its also done this way with parallel twin turbos on an inline 6 for the same reasons .

12cm evo X housing, now were talking business.

I think a call to GTP is in order... I need more info re reverse rotation turbos. There has got to be a reason why they are able to use SL2 and 20G wheels in the reverse rotation housings..

Need to get back on topic, poor Kando!

[Nee-san]

Try the evo forums mate,

They love those FP turbos !

Good mate of mine is about to put an FP RED onto his V, will be interesting to see the outcome.

At this point thinking around 300WKW with fairly reasonable response.

Will post back when we have data.

[fatz]

just grabbed two td06 10g turbos see what they are like

[Nee-san]

Twins will make a man out of you, Mulan style.

[fatz]

yea may stick them on my r31 for a laugh

when they come on boost at 6k

[SimonR32]

Nice work fatz... I assume you mean twin td06sl2-20g 10cm?!?

I wouldn't imagine they will be not too responsive but they will hammer hard once they come on. What power you aiming for?

[fatz]

those are the ones

massive fan of trust

have had 2530 with a single 20g

also had a zed with twins( it was fun at 1.8bar

but now have a purty flip flop exhuast manifold that will mount them slightly diffrent and a spare r31 that needs skidz

WOA, YOU!

How did you find the 20G on power for a 6?

How much power did it push? And what exhaust wheel were you running with what size rear housing?

Sorry for the attack, just trying to gauge as much as I can on the 20G topic.

Thanks,

[fatz]

was a td06sl2-20g 10cm of a twin kit put on a trust single kit

on a rb30/25 it was at full boost at 2300(12psi)

made 250rwkw at 12 psi

Sounds good, so it ran out of puff after that?

[fatz]

yea i have heard of people running 270rwkw

but on this engine ( tired a bit... blowby)

the most the poor little sucker could muster was 250rwkw

ran 114mph in a 1650kg car so sounds about right

in the zed it made just over 520rwkw with two of them thorugh a auto( allegedly)

felt dam fast the zed

[fatz]

anyway see what these kandos can do

then i shall applaud or rubish them

[GTScotT]

youve not seen the results from Simon? lol

Im tempted to go the kando SL2 20G but Im not sure if I should try something outrageous and go for an evo twinscoll housing to match.

Your results do give me some confidence that it would be an epic turbo for the RB25, 250kw@12psi and 12psi by 2300 would probably be no more than 1000rpm worse on a 2.5L (more like 500 I think) and would easily push the same figure with an extra 2psi. Evo dudesssss push these things to 1.8 bar NO WORRIES (actually they do that with the stock 16g too).

Majorly considering a simple T3 IW 8cm job when its available.. Kando = winnarr

[derryl]

Love the sound of these turbo's, very impressive!

Finally a turbo that bridges the gap between cheap ebay turbo's and expensive jap ones!

My mate put me onto this thread, but I'm still unsure of which one I should run:

rb30det with stock (healthy) internals....would be happy with 260-310 responsive kw's.....going in an s13 skidder (100% track car)

td06 or t67? 20g or 25g? 8cm, 10cm or 12cm?

[Harey]

If your that excited maybe just read through the thread.

The t67 with 10cm rear that Simon is running would be a great turbo for an RB30 although you will make more than 310rwkw pretty easily. Will you be running an aftermarket manifold and external wastegate?

[Chainfire]

Just a quick question, as I have recently purchased one of these turbo's (Identical to SimonR32)

One of the first things i noticed after taking it out of the box, was the fact that there was a small amount of shaft play. As in, you can move it from side to side (not enough for the blades to touch the housing) but they come very close.

So my question is, is this sort of thing normal for this type of turbo? SimonR32, was this the case with yours?

Or should I be sending it back for a replacement...

[Trozzle]

It's a bush bearing turbo, not ball bearing. There will be a small amount of shaft play since the bearing essentially floats in oil
