turbine 500 abarth 1.4 turbo on the 1.3 multijet

[dariuccio]

hey guys, I mounted the turbine and it was just what I thought.
at first I mounted with the impeller and the spiral suction good but I had problems with the impeller, why? "frizionava on the spindle
(it was a problem turning the bushing created was a few tenths too big) and then I decided to mount it with the impeller and spiral
intake of 500 and nut drain my original valve westgate deleted, and pressure operated valve pop off.
results (unexpected): the crowd goes into pressure already? at 2000rpm the engine rooms ? a beauty and still I have not done na map dedicated,
to 3000rpm keeps the gi? 1.3 bar and at 4000rpm holds 1.6 bar.
they are really surprised

the guys thought, and if there montassi injectors lancia lybra 115hp and a pair of camshafts redressed could reach the 130hp?
of course, with a map made with the controcazzi!
I'm waiting for opinions and advice

ciao.scusa if I'm intruding,but the ihi turbine mounted on the 500 abarth is on bushings and nn on the pads !!!

Do all these changes and then leave the nut exhaust
the original machined and a job done wrong, then I don't understand
you've deleted the valve westgate and used the pop off to adjust the pressure?
It was not enough to put on modified collector with the turbine of the mito 1.6 appropriately
changed?

[dariuccio]

for what reason ? a job done poorly
the performance, if not improved 100% I guarantee you that there is lacking a little. moreover, the work ? managed really well
and the breakfast excellent.
the valve pop off (which I still don't ? arrived) on diesel has the same principle of westgate with the difference that deflects the exhaust gases and the other the compressed air, but the juice does not change the fact that the turbine will be running? always strong. the turbine of the 500 I bought for the error of those who me the sent and honestly I could not
spend 2-300 euros or those that are for another turbine then, when I had a new still wrapped.
finally ? a challenge that I proposed to you, and are proud to have won!
but now could you tell me what do you think of affiancargli injectors lancia lybra and camshafts.
there arriaviamo at 130 horses???

Perhaps you have confused ideas on the operation of the valve, pop off, or you're explaining evil

[dariuccio]

no ideas-I have a very clear, let me explain better:
on the gasoline pop off you go to open when you release the gas pedal and you have a sudden increase and
abrupt pressure with risk of damage (water hammer), especially for the butterfly valve.
but if I apply it to a diesel and the taro for example 1.5 bar reached this pressure, she opens up and then you
close; now try to imagine this movement several times per second, what? the result?
you doing the open and close continually keeps the pressure constant at the value decided by me.
theoretically it should work

also,sorry to post another message, but I hadn't read before,
I have not written the turbine will be running? always but I have written the turbine will be running? always strong
in the sense that even when you open the valve to pop off and download the pressure outside the turbine is not rallenter? his
rotation as is the case with the westgate and this should also mean less turbo lag

well of crap I have heard already enough from what I read I understand that you don't know how it works the by-pass valve or pop-off, which has the task to drive out some of the pressure that is to be established in the pipes when you release the gas pedal, or dropping it closes the valve with the result that the turbine continues to rotate, and to send the air but was unable to pass because of this and closed, then the water hammer is the turbine is not the valve as you say.

Does not work this system you will have a pressure dancer and the turbine will be in autodistruzzione.

hello I invite you in the presentation section, thanks.

[dariuccio]

I state that I have already submitted, but we review it anyway.
I admit that I confused a bit with the ideas but between the throttle valve and the turbine, and I apologize for this but the fact remains that
the principle of operation that I have described ? identical to your I don't know if you've noticed (WRITING IN the MOST ABSOLUTE RESPECT) I also believe that sin is a bit presumptuous even why? some time ago I built a pop off
crafted with a tappet fiat marea as the piston ostruttore inserted in a tube of the fountain pricked by me and
screwed on the intercooler.
results:the pressure was more constant the only annoying thing ? the fact that it seems to have a broken pipe.
having said this, I thank you anyway for your tips and I hope that this exchange of views remain constructive.
