Kando Dynamics Turbo

[Joshbigt62r]

I also have the same question if anyone has done it, except I want to put k

the billett 71mm comp wheel in my hks 2535.

[Pridenjoy]

it wont work

cheers

darren

Reason as to why darren?

Cheers

[jet_r31]

massive compressor wheel to turbine flow mismatch

youll get massive lag from the turbine trying to drive that big comp wheel..then when it comes on, up top you will get power capped

by massive turbine backpressure from to small a turbine wheel

Area under the curve is the go, not a pretty number up top in the last 500rpm of powerband

Its just robbing peter to pay paul and will never work, especially on a larger capacity motor..

the t04z wheel doesnt work with the 3540 turbine, although lots of people have done it...its shitsville city..

Wouldn't fitting a 71mm comp wheel to a GT2535 just make it a GT-RS ?

And don't they work a treat on RB25s for response ?

[Joshbigt62r]

Well thats what I thought but stao said it will just make the turbo choke and is basically a waste of time. I thought a bilket hks 2871 would romp on the street on e85. In guiltoys thread he made 280kw at wheels on e85 and reckons he could of pushed the little 2535 even harder. So billet should kick ass even more I thought I even though to make the rear not choke bolt a kando t3 gt28 .73 vband rear on with a 38mm gate welded off it. Or even a 38mm gate welded off the hks .64 rear housing. Because the hks rears on the 2535's almost glow white hot when given a hiding. Not sure but maybe could even bore the internal gate out further to help flow a bit? Any thoughts.

Cheers darren, much appreciated.

If you want response just run a .2 housing.

At some point the rear housing becomes a restriction and the gas speeds can't get any faster. As the smallest part of the entire system, that nozzle is the critical point. Too small and you will have great bottom end, to large and the top end will romp at the expense of low down.

Every rear housing is different and the nozzle isn't a particular size compared to AR, it changes depending on brand and turbo size. The HKS .64 is much smaller than the Garrett GT30 .64 for example, and was never designed to be pushing 300atw. Many have melted GTRS's at the track, and I am confident shoving a billet compressor which may flow up to 20% more air will only make it worse. Externally gated housing may help, but I haven't tried it on anything quite that small.

Melted GT-RS at the track?

[scotty nm35]

The threads are all on here somewhere if you have a search Roy.

[Roy]

Meh, cant say I am that interested. Just a strange statement to read

[Super Drager]

Yep apparently the flanges on the turbo were warping due to excess heat and the guy had to have the flange machined several times.

Josh the changes you're asking about are too extensive to worry about modifying the HKS/Garrett.

If you aren't opposed to running an external gate off the housing and want to try out a Kinugawa, try a TDO6SL2-20G, or have Hypergear build one with their 20.5G compressor. Response and area under the curve, and not ridiculously priced.

[Joshbigt62r]

Yeah I In think ill stuff the 2535 off and maybe go what you just recommendon dale. External gate off housing is no problem. What powee that make pushed to it limits? Should just go back to the 6boob hi mount. To many bloodyoptions. Ultimately id love 330-350kw with killer response.

[Dale FZ1]

^^ And don't we all

Some of your other posts indicate going with E85. Not sure that the 20G would run past the 300kW mark, perhaps the HG 20.5G would go very close to fitting the bill. You'd expect pretty rapid response capability with either.

Once you start going with fabricated manifolds and custom modified versions of the Kinugawa you'd be mad to not look further. I'm referring to BW and split pulse options. Depending on model/spec they can be very cost effective (if a little more difficult to fit due to physical size of the unit).

[Joshbigt62r]

Would thw borgy 7670 iwg need a custom 6boob made or just a standard work you think? That should make good response and minimum 330kw on e85.sorry to post this in the kando thread

20G will do 300rwkws on E85 easy. My RB20 made 310rwkws on 22ish psi on a dyno that certainly isnt known for high readings. So will make 310 on any dyno...with rather mega response on a 25

[Dale FZ1]

Josh - you'd have to chase an opinion from 6boost about what is needed for a BW. Look closely at the S200 range. From memory they have split pulse or open housings, using T4 flange. Perhaps get a thread going on the BW range, there's quite a bit on the 8374 but you are throwing ideas around about the smaller ones.

Troy - you have the experience in the area of the TDO6-20G so I'll yield here. 300-310kW is strong by any measure but not always that easy to crack. Fuel would play a big role with this combination I reckon.

There are Evos running up around the 400hp mark with the TDO6SL-20G on E85 but compressor flow/efficiency has got to be running out by then. Response/mid range should be the goal and one of these should make a decent account of itself.

[Roy]

Sorry, thought we were talking E85. On 100 i made 280 odd backed off to 270rwkws for track work. 98 was 260 for track work...on E85 made 306rwkws off the gate with boost falling off.

Another forum goer (Artz) earlier in this thread had the gate off the housing and std manifold on E85 that made the same power

Note how the 20G falls over on top end. This is from our re-worked version: SL20.5 mentioned earlier. It is made to have the same down low torque as the 20G, while holding the power band up top. Running against Kando's TD06L2-20G on a standard RB25det motor, Same response, more power with much wider power band. Nothing is changed apart from the turbocharger. Price difference is within $100 to listed kando item.

The red line was Pulp...and only at 1 bar boost for reasons I cant rememeber....

Staos turbo with the upgraded comp wheel is the go now tho...Would def of used that if it was available at the time
