Will you keep the exhaust pipe sticking out like that?

no, it will be cut

[nadir]

nice mate! very nice! btw u use your car only in day time?

[nervas]

was on dyno 600hp@7200rpm and 600Nm from 6000-7200rpm with 1.7bar boost. 500Nm from 4500rpm.

still having some problems with EGT.. ~950C with this Holset HX40/KKK26 I guest I'm having backpressure isues, and need to change hot size..(


and then on track (with 1.4bar and it was fa!@$! fast, too fast.....

[Billman]

You got 600 bhp with the K26 6 exhaust housing?

You are using this Holset on the 2.5 or in the new block with 2.2 liters? you got 950 celcius before or after the turbo and at what Boost pressure and RPM? What Exhaust manifold do you use?

What cams do you use?
How is the boosting and in what gear?
What is the weight of the car?
Can you show us the Dyno and the some videos??

Sorry for the many questions and congrats. It is a Very nice project!

Give us some videos!!!

I don't have video

950C before turbo, have no log with pressure and rpm exhaust manifold custom made

cams custom made
boost is from ~3800rpm and up till the end, if I make 1,2bar boost, from ~5800rpm till 7000 it raises ~1,3-1,4bar
Car weight 1100kg

dyno is attached, video only on phone and I don't know how to put it on PC

[Billman]

Nervas,

how is the boost controlled? You set it i.e. 1.4 bar and it does it like this or you have a boost controller so you can set i.e. 1.7 OB and 1.4 at the rev limiter?

with greddy profec b-specII. I set 1,2 bar and I have 1,2 bar from 3800rpm till 5500rpm, but it rises from 5500 till 6800rpm till 1.4bar. but if I set 1.7bar I have it from 4500rpm till rev limiter.
I think, that stock WG is not capable to lower boost below 1,4bar with my setup and backpressure

[Billman]

Yes maybe the wastegate if too small for the small turbine housing you have and this HP level. you either need to use bigger WG or bigger housing. If the manifold is custom made then why dont you measure the backpressure?

Are going for some Divided holset housing or a K26 8 housing?

Bulleye power produce some 0.76 A/R housing for the HX40 with the T3 flange.

I have no much time till 1000km endurance race on July 16-19, so will talk to local guys (www.turboservisas.lt) what they can do in this case.. I think that we will find a solution. If I will need to change flanges, then I will need to redone downpipe also..

[Billman]

Then your solution would be a K26 8 or a K26 10 (this with number 10 was apparently only available from MTM but maybe with good contacts you get what you need. Please inform me about the solution you are going to find. I also have a K26 6 and was thinking of something bigger. Please also ask prices (maybe i buy it from them where you going to buy it).

WTF? What track is it?

the same, you are driving sometimes

Zoom and photoshop tricks!

That turn before start/finish looks way different from inside the car (checked my onboard videos to find where in the hell are those painted barriers).
