Kando Dynamics Turbo

[WYTSKY]

Guys, I have been reading this thread alot actually as I went in Sam's 305rwkw 4dr 32 and these turbos are very similar to the td06 he ran.

The power with these is very impressive, while I still enjoy my Garrett, I cannot get outta my mind the td06 copy simply when I went for a drive with Sam.

Essentially it was like a light switch, all of a sudden this absolute enormous RUSH and in 4th we went sideways. He was laughing his ass off, as was I... while screaming.... the Garrett by comparison is extremely linear and pulls harder and harder, but sometimes I like that instant smack of boost.

I've spent too much on my setup now to change, but I assure you that td06 copy DID push 305rwkw

Make up your mind, you often chastise 56trim GT3076Rs for 52trim ones - they are barely different in size. If the compressor affects response that little, 52trim GT30Rs are redundant

That is all oversimplified anyway, the compressor has a lot of affect on how boost threshold is achieved - loosely speaking the exducer is responsible for accelerating the air, the inducer is responsible for drawing it in.

You can actually make a more "responsive" turbo by having a larger sized exducer (fine balance between extra mass and extra "throw" off the tips which is where extended tips come into play).

Same goes for Garrett GT series turbines, they are often physically smaller for the equivalent than Mitsi/Borg turbos but they use a less abrupt blade attack angle through the turbine, meaning they are more of a high speed turbo. Lighter, but don't necessarily respond as fast to low speed gases for the equivalent size... so give or take a bit a Garrett GT series turbine would be normally the equivalent in response and flow to a larger say Borg Warner one, for sake of arguement.

I could go on for fricken ages, but the gist of what I'm saying is don't assume that all things are comparable just by mm measurements of a pair of wheels on different turbos.

Obviously size and trim are only a part of the equation, I know, as there is the design involved aswell. Be it so simple why would new technology arrise? We have always had control over size and trim, its not like it takes 30 years to think of a new size and trim combo.

What I'm saying is, while I have bastardised and simplified the terms to a ridiculous extent, I realistically just wanted to put forward that I have lost faith in simply dropping compressor size to make up for a lack of response. I am more so looking towards matching the largest and most efficient compressor to turbine as possible. That being said I still like the 52t 3037 combo better than I do the 56

I also would like to put forward that my hunt is not for the most PSI at the lowest RPM but actually the broadest powerband within usable RPM limits, irrespective of boost pressure acheived at any RPM.

I'd go out on a limb here and say the first person to do a good twin scroll GTX3071R on an RB25DET will become superman until the next best thing comes along.

eg variable vane with a simple to program controller, om nom nom

Seeing as this is a Kando thread, a TD06-18G + TD07 compound setup would be monsterous

Forget the twin scroll, just a GTX3071R on a 6boober with a decent gate

[GTScotT]

LOL @ Superman.

Someone needs to try the 10cm 3037 also, he may be said Superman based on popularity!

I have never read many good things about the TD05-20G. Seems to be a bit of a mismatch in wheel sizes. The TD05-18G is the way to go it seems, the 20G is just too much compressor to be spun by the little TD05 wheel....also on a plain bearing turbo running a mismatch of wheel sizes means you end up with higher bearing loads as at rpm as the axial load increases...or so I read

But the TD06-18G could be a good thing. I have been told the TD06 wheel is a good thing and its the 20G compressor that makes the TD06-20G as laggy as it is. So a TD06-18G could be a good thing, good sized turbine so that you can get good boost and flow without too much back pressure and a light little 18G wheel that is good for 240-250rwkws. I think the problem is the shafts are different diameters

[GTScotT]

I actually have to agree regarding what TD05 20G results Ive seen... Yet am dubious of the ability of an 18G.

When this all gets too difficult I'll buy an SL2 25G lol

[Lithium]

I only would use the 18G as a base for a compound turbo setup

car is booked in for a tune next monday, finally ahha. Somthing i noticed is defferent between my T67 and simon/batteries, mine had a bullet type nut on the compressor, came like that from factory...

[Lithium]

Look forward to seeing the results - good luck

[GTScotT]

+1 exciting news!

Goodluck!

Well now I'm just jealous! haha

Is your turbo ID tag the same as mine, as in a Kinugawa tag with T67-25g as the model?

Good luck with the tune

[OMY31T]

how jealous? hahahaha. seriously, this is how it was when i got it.

and anyone in vic that might be attending the show n shine at carribean gardens on sunday the 22nd of may, i should be there with the car, i might be entering with another club just for the hell of it, not for trophies, just for somthing to do.

as for the tune... it will be interesting to see, especially auto with a powerFC, ive since been told that powerFC's werent made for autos.... makes me wonder if the ecu is a powerFC ive never looked lol, thats what i was told it had when i bought it. i know its not a stock ecu because i have a dyno sheet from the previous build from the previous owner, oh well might pull it out tomorrow and double check it.

the guy thats tuning it thinks we should easily make 300rwkw on 17psi without pushing the engine 2 hard. its being road tuned apparently.. i dont know much about the tuning side of things, just the mechanics of it all. then cross fingers with some slicks, + the auto, im hoping for a mid to low 11 as simon has done.

btw simon what oil are you running in your engine, i need to throw in some new stuff before the tune. im running Motul Turbolight 10w-40, but ive been told i should go up to a 10w-60. any thoughts?

cheers.

hmm Im not too sure about the consistency of Mr Kinuagawa.

My right angle oil line feed is different to both of yours.

Initially I received the wrong V band flange but I contacted him and I had a new one sent to my door inside a week.

He also had 2 different listings for the T67 on ebay with one being $50 cheaper, I messaged him about this and he said they were exactly the same...

nothing major but something to be aware of if you buy one.

Good luck with the tune OMY31T im interested to see your results with the stock plenum vs Simon's with the "freddy".

[OMY31T]

funnily enough my turbo was the $50 cheaper one, and i got a cool nut on the comp hahahah

[SimonR32]

I use castrol edge 10-60 :-)

[fatz]

finally my twin 20g kit is comming

hopefully it can be slapped on quickely

Going on a RB26 yeah? Has it been built?
