Kando Dynamics Turbo

[OMY31T]

hahaha

$10 says the housing is identical in size to yours Simon.

That would mean its profiled for a 61mm wheel when the garrett item is 60mm.. I would be both dubious and highly intrigued! lol

[Lithium]

I would keep my $500 and T67 Tiny bit more lag for lots better top end wins for me!

He is going to try by running silly boost on his car to try and make more power than mine, good luck I say

Will be very interesting to see how it goes, let us know. Will it be on the same hub dyno? Would be very interesting to see an overlay. I'm leaning towards the GT3076R not QUITE reaching the T67 (if it has fully equivalent setup) power but would like to see a pretty mental midrange - assuming he will also be running E85. Slightly quicker, maybe... the extra $500 has to prove some worth somewhere

I tried quite hard to convince the owner of a car I will be tuning soon to go a KD T67-25G on his Neo RB25 GTS4 but after I took him in my car (GT3076R) to convince him to get rid of the POS "T3/T4" he had he basically won't consider any other options.

I don't think it would be the same housing, the appear to machine in house so it wouldn't be hard to reprofile...

Also note the way that the rear housing connects to the CHRA is different, the T67 has a v-band where the Garrett is 6 bolt.

EDIT: They have also profiled it for a GT35R wheel by the looks so I'll take your $10

Yeah same hub dyno (it's his dyno haha)

Will definitely get a comparo graph when it's finished, mind you his will probably be running stupid massive boost so might be hard to compare.

Tell the owner my car which doesn't have cams ran 11.0 @ 132.5mph, while my mates has Tomei poncams with GT3076R and ran 11.5 @ 127mph (Mind you his is a R34 so a bit heavier)

[Lithium]

So heavier car, and he hasn't done the hero tune yet? They aren't worlds apart then... I was going to qualify my statement with "all other things being equal" but then reckoned you'd know what I meant.

11.5 @ 127mph is quite nice going (well your 11.0 @ 132mph is very nice going too) in an R34 - what boost was it on? E85 I am guessing?

Yours has standard cams and is gaining power to 8100rpm? Something doesn't sound right there...

Nah he has a "hero" tune haha It made 500hp on the same dyno as mine made 520hp

It's not a fair comparison, mainly due to weight... But it is the best I have to go on (same fuel, same tuner, similar boost and similar mods apart from turbo)

100% has standard cams. They were checked when the motor was installed, look at graph below for example of gaining power till 8100rpm (power figure is inflated by correction method, makes 520hp without it)

[Lithium]

Thats very strange, what manifolds? Full boost at 4700rpm as well!? Do you have a boost plot for that run?

[SimonR32]

6boost T3 high mount manifold. Full boost (1.6bar) on the dyno just before 4500rpm and on the road in 4th gear before 4000rpm. No boost plot from that run but similar run seen below

[Lithium]

I meant intake manifold as well, or do you have a stock one? For the car to be building power up to those rpm its not going to be a turbo thing, its the tuning of the engine itself - the T67 is dropping boost yet power is still climbing. People do all sorts of things to engines to keep their torque curve holding on up to those rpm, whatever you have done to get that happening... I want

China copy Greddy manifold... Also exhaust cam gear at -4deg

It's the turbo not the motor, on the same dyno there have been countless GT3076R RB25 cars with similar mods that all fall over between 7000-7500rpm

[Rolls]

Long shot but could it be the fact it is a hub dyno instead of a wheel dyno? You would think the correction would take care of this but perhaps it is partially to do with that?

Thats very interesting, nicely setup - though I am completely unconvinced that if I put a T67-25G on my car it would suddenly start climbing in power up to 8000rpm. The T67 obviously has to be able to more the air up to there, but your actual engine has a ridiculously good ability to breathe air.

Imho the T67 is being made to look particularly good up high there due to the combination of bits, but makes comparisons a bit hard. Either that or your RPM calibration is screwed.

Nah, its definitely nothing to do with that. The only car I have tuned so far to have a power curve that "revvy" on a Dynapack was a fully built Honda Prelude motor (12.5:1 compression, head porting and 312deg "VTEC" cams) which was starting to level off at around 8000rpm making around 180kw @ axles.

Just to show you it's not just my car but rather the T67-25g turbo, I have below some results that Trent from STATUS has posted in the past.

If you have a look here a comparison of a 3071R vs T67, only goes to 7200rpm but you can see power is still climbing while Garrett has fallen over.

Here is another one, once again only revving to 7200rpm... But clearly not falling over any time soon

WTF SIF plot so close to a 3071R?!

HUH?!

Pretty sure simon has a neo motor as well, better head, maybe all the dyno's we've seen are r33 spec rb25s?

[Lithium]

Peak power at 7800rpm... stock RB26s don't usually make peak power up there!

240kw @ axles for a GT3071R, hmmm... thats not quite right either.

[SimonR32]

HUH?!

See below, he picked the averages of both of the runs he had on file.

runs @ 17psi and i have picked the best average of both. The T67 is a bit wavy but has since been sorted.

Nah mine is just a R33 RB25DET

240kw @ axles for a GT3071R, hmmm... thats not quite right either.

It's more like 250kw at the hubs and it's about right considering it's only running 17psi considering they max out around 270-280kw at 20psi

I seen that before. That T67 is running on 14sec ramp against a 3071 looks like on a 9 sec ramp. Not really a fare comparsion. Simon your original sheet would present it better.
