Kando Dynamics Turbo

It would be more sensible to compare it to the GTX though, as they are both billet and can both run high boost efficiently. As said though, there are no direct comparisons or even decent GTX3076 results on built engines. Shame mine isn't a manual, although stock manifolds and cams will be restricting my output severely anyway.

Too many variables unfortunately, but the HTA definitely spools nicely. Lithium, can you buy the HTA 3071 chra separately by chance, and will it drop in to standard GT3071 housings?

You can buy less exhaust housing, can order with 71, 73 or 76 HTA just by simply emailing and asking.

About $2,500 landed IIRC.

Ok so I finally pulled my finger out and sorted my car out for a tune with the TD06H-25G Billet compressor. Mind you these results are on a Rb3025 Neo running 260deg cams, with BP98 and only roughly 19psi. Apparently it kept blowing a hose off at any thing higher so I need to weld a barb on it to be able to lean on it further.

thats a good result, whats going there at the higher RPMS?

Running it on 20psi proves nothing - you could think this turbo is no better than the old GT3076R aside from coming on a bit earlier at that boost level. Sure, the 28-24psi spike is going to make the midrange look artificially higher but in most cases that is actually the reason a car with a similar setup will make more torque than another, unless one has a restriction (which CAN be the turbo maxing out). If you want to see where it hits 20psi, follow the dyno plot to that point.

Also I am not at all convinced of the hub dyno vs rolling road dyno comparison being equal in this case - when we were discussing this HTA3076 upgrade I investigated lots of JEM's dyno results to get a feel for what to predict the power potential of it as, the numbers which are coming from the hub dyno in this thread and the HG one are often showing cars with stock cams etc making similar or more power per psi than what you would see at JEM's dyno with cams/head work etc. I'd be happy to be proven wrong, as I like to be able to see the wood for the trees and help EVERYONE improve their understanding of everything but I am just calling it how I see it at this stage.

running it at 20psi would give a direct and equal comparison surely, allowing the HTA to ramp up 28psi probably would effect the boost curve, can you really just follow the graph to that point and make comparisons? At 20psi , its 200rpm difference anyway, I wouldn't be surprised if the two graphs were almost identical on 20psi.. its all about the transient response it seems.

most people are interested in using a turbo for there stock motor so running it on 20psi would prove a lot..

not 100% sure but I'm not really too worried either hahah. I can't feel it doing any thing funny, all I know is that its spinning Achillies 123S's when rolling on in 2nd and probly 3rd.

Bahaha nice, is that a 10 or 12cm?

You reckon that much? I would have thought it would be that WITH the housing

[GTScotT]

Sorry I did mean with the housing.

Last time I emailed them it was about that much, and they were willing to discount about between 1-200 for the housing. Not enough in my eyes but oh well.

[urtwhistle]

12cm. 1st gear is now useless haha

[GTScotT]

olololol nice.

Am planning to put a 10cm one on my brothers shitma motor. Just in the process of building the new motor now.

Looks like a good result. Boost falling away slightly up high, does the tuner indicate whether it simply requires a bit of fine tuning of the BC, or is the 12cm housing maybe heading towards its capacity with that combination?

Interested to hear if it ramps up progressively or comes on with a rush. Some people might not have noticed that this turbine spec is the big brother to what's fitted to the T67-25G

[nanes]

Finally some 12cm results!

Anti surge comp cover and external gate?

Decent results for pump fuel, I've got the same turbo as yours to go on a single cam rb30 on e85 and have been looking everywhere for results.

Please share yours when the time comes also, a friend has a sideline RB30e+t which is considering similar options too.

[urtwhistle]

I would say its the crappy power fc boost controller. I also just noticed that injector duty is at full nearing redline. So my 660cc injectors have to go before winding any more boost into it.

Yeah antisurge and 50mm external gate.

With the 3l it actually feels pretty dam good at how it ramps up. It might be a light switch on a smaller motor

[Dale FZ1]

Hope the fuel delivery woes to the injectors have been sorted and aren't contributing to the high duty cycle? The results are very promising but I'd think 660 injectors would comfortably feed 460rwhp of pump 98. Might be worth running a fuel flow test rig on the dyno to check.

[urtwhistle]

I would have thought 660's should be heaps too.

I need to log the duty next time I drive it with my laptop. I only noticed it when I was looking at the hand controller and it showed the peak reading. Just prior to that I was tapping the rev limiter so it might have the last few cells set to dump in masses of fuel. The fuel issues that you mentioned, I pulled the pump out and changed the pickup point and it doesn't seem to be surging when cornering any more.

Well boys, results are in. Very happy with the way JEM has handled both me and the car. Would highly recommend them.

I forgot to grab my power run, but put simply.... 238rwkw @ 21.5psi.

Will grab the dyno sheet next week and upload. Car feels so good/fun to drive.

[GTScotT]

Thats a good result Kane

For years the RB20 staple was Roys 260kw, you have managed to get 238(240~) with a TD05H 18G and a standard manifold which would arguably be a punchier combo and still not giving too many killa wasps away. Plus we all know the JEM dyno is legit as they come. Awesome stuff!

I bet your stoked! Come take us for a wrap if your ever in the Liverpool area.

[Kane_R32]

Scott, I work in Warwick Farm, so I'm sure we can organise something (not my daily though).

I was a little worried it wouldnt get the number I asked, and when Dean asked me what I wanted to acheive (240 on 22psi), I was stoked that it was achieved.

Keen to see the graph. Car really comes alive after 18psi.

Very nice result, what fuel and other mods?

Have booked the dyno to tune my mates S14 with a 8cm TD05H-Evo3 16G on flex fuel, we will go to full E85 and at this stage may go up to around 20-21psi. Will post results for that when it's done.

Do people realise (or have any thoughts) on the sentiment that the Evo3 16G is often considered to flow similar to the 18G? This fact was part of the grounds we chose the Evo16G compressor over the 18G though will soon enough know if that was folly. So far it happily pumping enough air to keep the SR20's thirst for air quenched, so seems good so far.

Also, I had previously posted ~3700rpm for full boost - that was rolling on throttle, later testing showed that it gets 19psi by 3500rpm in 3rd gear and holds power nicely past 6000rpm, compared to the old PE1420 which hit a wall before 6000rpm.
