Acq 10vt - oldschool turbo power

[Takumi]

not sure if it's stock. Have put it long time, so can't answer that ( housing didnt had any AR numbers, just some random numbers. Traded it for HX35 kkk26 #6.

So it's a kkk hotside, paired to hx40x

[Takumi]

no, this one is T3. Before had HX35 paired with KKK.

Hello,

I have also installed the COP 10vt. After 10000tkm the upper part from the spark plug disengaged by the vibrations from the engine. I recommend a holder or something for the ignition coils.

Best regards

How much power do you think the hx40 is able to make on a 10VT? I don't think i have enough funds to finish my 20vt so i am also planing on putting the hx40 on the 10v and hope it doesn't blow (stock rods).

Hey!
Have little time, but still on track for more HP
Anyways after latest MODs i felt lack of gains, LOGs didn't show much of improvement and oddly i was getting DP gasket blown frequently. Ok - it was time to test exhaus BP.
And guess what, my 3inch exhaust with 1 muffler on boost is giving me 1bar of BP(total exhaust manifold BP boosting 2bar is 2,4bar)
Thinking that muffler is the culprit i removed it and still the same.

Question is - could this be because of WG that goes to DP and makes some kind of curtain for main stream flow? Because i removed exhaust totally(left DP and WG as seperate) and top end differance was like WOW(VE ego corr went like +12% above midrange to keep 0.8lambda and IAT dropped, EGT didn't any significant differance).
How should i make a proper exhaust? Is 3inch enough for hx40 boosting 2bar+? Still not sure about HP, but my 1100c are @92% DC with E85 so there should be some gasses escaping. Open WG is not an option, as i didn't like it before
How latest exhaust looks with WG inlet could be seen:



Any ideas welcome
Thanks!

Keep the wastgate separate and use a separate silencer for it. See my urq thread

Ok, so the issue was...



Now i get 0,15bar peak
P.S. WG dump is now external.

And how does it drive with this restriction removed?
