Om605 compound turbo build, my Corolla Ke70 tracktoy
I do not understand much of this but what I do understand is there is no planing at all, how can there be success in the end!? Two turbo set up like this do not by accident going to work. If you want to do a compound set up you want a lot of boost in the first place, one turbo out of pressure ratio and faster spool. If you want a sequential set up these turbos is way to close to each other if you want good performance, just look at the R2S systems for example to start with.
Petter please forgive me for saying it but if some one say to me -"I have bougt the turbos from Petter, the Norwegian go-to-guy and Holset expert" there has been putting a lot of trust in you and you answer -"My compound models where based on shitty flowing VAG engines so I didn't see this problem until I upgraded my model for these OM60* engines" well that make me speechless
And please do not make this into a flame war, that is not the point at all here, I think we can agree on that this is a great build and need some help for getting turbo to work properly,
stamsaas come up with what you want in performance so Peter can help you completing it! I do not know holset turbos that well for helping you out here, simply there is nothing to work on.
Simply I just wanted to know how you think in the set up and by discussing it some useful information to the members of this forum

Well Petter, yes I do not know much, in my opinion the more you do know, the more you realise you do not know, you seams to have a better memory then me too since I can not remember asking you for the compressor and turbine maps for the Holsets the discussion at www.tdiclub.com with you was much more pleasant there I must say if you want sand låde nivå med kasta grus på varandra så är ja inte alls intresserad men min ena son älskar det, du kanske vill leka med honom? sorry could not help my self there, at some circumstances the horn in the forehead starts to grow out no matter how hard I try
I am no expert But I do know the basic in turbo machinery, I am a engineer to profession so please get it down in technical terms and we can discuss sizing, perhaps we both will learn something out it so I think it would be of good benefits for both of us and a great deal of fun actually, I will look forward to do that with you but then you did say something about not want to share compressor or turbine maps so it really got hard fast, Hmm have you worked for precession turbo, they like secrets not to mention bosch
Guess what, I am quite happy getting my hands dirty, Oh I am building some but some parts has not really taken the away I would hope and when some close friends died I lost a lost a lot of momentum and I am not the "The Boy with the Golden Trousers"
If I only know how to post pictures I could give you some pictures and I guess that would give you a better picture...

Hijacked? We are discussing this exact build!

Just to say I am a fan of this thread. There is not enough discussion of compound turbo design on STD.
How is that hx30 super over he200wg combo working for you alcaid?

Tanks nice work.
I recall seeing that even ARP studs stretch more than the factory cummins head bolts. All this stud stuff is kind of a load of crap although it preserves the block threads. Unless the stud breaks.
I dont mind any discution in the tread as long its about this setup but I have 100% thrust in Petter and what he does.
Update time!
Last weekend I did some small things, and after that I fired it up and got it to normal temp
Some pics for you guys
Put on new locks to the trunk as the oem had to go with with the ducktail
New steeringwheel, bigger so the car is better to drive. Have to reweld the throtle a bit
Also fitted New breathing to the catchtank.
And after the pics, what about a little clip?
Sorry to hijack. I am just trying to understand the concepts behind designing a compound setup. Very big congratulations for what you have done with your car to date. Please continue so we can all learn more from it and enjoy.

Borrowed cornerweights, and the total weight was 1117kg with full fuel cell (60l). I allso forgot to take out a full 20l of diesel that was in the car, and there was some stuff in the trunk, but right under 1100kg in total. The floor was not perfect level so the rear right was a bit higher, so the rear right and front left are heavier because of that, but, the front rear balance is 57,56% front and 42,43% rear. Roughly 170kg lighter ass than front
This makes it to be less than 3kg for each 1wHp
Pics ;
This weekend have been a blast! The car hold it together all 3 days with alot drivingtime
Here are som pics and videoclips
Ready for driving the next day
some pics from driving
The mic that I had on the rear of the car was a fluffy light gray thing, but it has changed during the weekend.....
but after burning about 60liters of diesel, it gets a bit darker...
had over 200kmt at the long straight several times
In the last heat it had trown quite a bit of oil through the breather, not seen on why yet..
And a video from the way home
More pics and videos will come
What was the final turbocharger combination? Did you collect any temperature and pressure data to see which of the two turbos was doing the work across the load and rpm range?
