spanish ,why? can you see the name of the bidder?

[Ruffiano]

You could see previous purchase history which was in Spanish

Any updates on this turbo folks?

i know the guy who won the bid

he told me it, but he is not sure about if he will use the turbo or not

i would like to see more dyno draws about this special turbo

[Ross]

He beat me to the final bid... I forgot what time the auction ended and missed it

If he doesn't want to use it and decided to sell, drop me a line, but it would have to be by the end of May

I was hoping to see a write-up from prj on his experience with one by now, I am hoping to have a little first-hand experience of it this week

[prj]

Ross, I might not fit it...
I think I will go K26/K27 hybrid, because that would max out my exhaust, intercooler, rods etc... just so I am not tempted to upgrade more, since that would be hugely expensive...

I am not sure yet though. Sorry to keep you waiting so long, but I have no time to work on my car, because I work on other cars every weekend!

[Sir Buff]

What K26/K27 hybrid do you prefer Dmitri?

[prj]

One that I will hopefully be provided with...

[Sir Buff]

There exists very bad hybrids with huge heavy compressor wheels. Take one with a "modern" little Coldside ;-)

I'm a bit confused about the numbers you guys talk here. This turbo will not make more top end power than a RS2 unit. Period.

Do you intend to do 3b stuff?

I can offer 3B chipset for K24-7400. I have mapped such car. I did like the turbo.

Surge problems on certain Garretts may me be partially or even fully solved by optimising cam timing and using more agressive cams. After all surge will happen only when pressure ratio rises too high for the given air flow. Better natural flow in the engine keeps pressure ratio lower. No rocket science really.

I might sell my K27-3072/K26 #8 + MTM sport quattro manifold soon... Similar units were used by MTM in their RSR 428hp conversion.

[prj]

It will certainly not make more top-end power, but it gets pretty close.
The wheel design is a decade newer and more efficient.

That said, I think there might be a difference between sticking it into machined K24 housings or using it's compressor housing and a K26 #6 housing.
Your 3B chipset used the first option IIRC, it might make more power using the second one...

Without dyno numbers it's just speculation... but I got a pretty good deal on a K26/K27, so I don't see the reason to fit this to my car anymore.
I will try to sell a package - turbo + rs2 injectors + live mapping session in my country, maybe someone will be interested and we can have some numbers.

[porkkis]

The turbine is the restrictor. 350hp crank absolute max as long as it's 50mm exdu and in 6cm2 housing. And at that point it's pretty hot in there, 950+.

Agreed
We do have a graph in this thread showing ~360hp though...

[porkkis]

They're just probably slightly shorter legged horses.

Dyno is a good device for measuring difference during tuning. For exact power figures... well umh.
That 360 car might show 320 in some other dyno. Which one is correct? Probably neighter.
