Have you got a result yet? I am starting to think that he has blown it up and is just stalling for time, no one should take that long to tune it.

hey guys im not going to bullshit you. having some issues with it still. somethings amiss with it not making correct power. im yet to get the car back or see a dyno chart (tuner isnt finished doing the top end tune on it or touch the cam timing) its making roughly 170kw@14psi @ 7500 (he hasnt reved it past 7500 yet ive told him to rev it to 8500 hahaha) (yes wtf you say :evil: me too.) engine is fine nothing wrong there had a problem with the thermostat pulsating so hes removed that for the moment to finish tuning it.

not sure what could be the problem with it atm (i know what your going to say "yes i realise its a ca") but hopefully it can be ironed out (the issue with power etc) had problems with the gate holding enough boost. tune is not complete so that is not the final figure,

I dont want this to turn into a Dumhead i told you so thread (ive past the assumed power of what he said it would hit max :P)

im going to go down there tomorrow morning and check things out to see the graph and to see what needs to be done to make some descent power out of it (may need my boost controller installed on it as im pretty sure the turbo is not in its efficiency range yet).

alittle disheartened with this project. (could have saved the cash and run my original setup and made the same power grrr :evil: but tuning isnt complete yet so will have to see shorty.

cheers
neil

hey that's still within normal dyno error margin of 160 :P

Nah there's no fundamental reason why the engine wouldn't make the power, so I'd say it's just a matter of getting the tune right (including the cam timing!).

They're always going to be a slightly difficult engine to tune properly though due to things like the fact that fuel is only injected into one intake port on each cylinder so you get funny AFR variations in the chamber, etc.
Maybe it's worth doing an 8 injector setup, or moving the injectors further out along the intake runners?

As for the dollars, even if it makes 400rwkw I'll still be making some sort of nasty comment about that :P

170@14 is pretty much spot on. I wouldn't be holding my breath for much more at that boost if I were you.

risking how would it only make 170kw@14psi simons car made 200kw+@15psi on a td06-19c (smaller than the td06-20g) ?

yeh wait and see i guess :S

maybe it was a magic psi?

hahahaha. sam (dr_drift) tuned it (simons car). (who im mates with) even he said it should be making alot more than what it currently is. grrr could have got this pissy power with the t28 440cc injectors a remap and a z32 afm. shit.

It's horrible when you don't get the power you expect, especially when you have gone to so much trouble. Guess that is why I set my expectations low and would rather be plesantly suprised.

nearly time to give it up dude? conceed defeat and admit what everyone has been telling you? :-)

no damit i wont do that.

found what the problem is with it. cam timing is way out (cheap custom cam gears havent helped so stock ones are going back on for now). cat may be blocked. should have more updates shortly. cat is getting a piece of 3" pipe hehe and the timing will be sorted.

hmmm.. 170rwkw at 14psi.. thats a pretty poor effort ;) My car makes 190rwkw at 8 psi and yes its a SR20DET what more do I need to say? NOTHING

bhappy you are a pretty poor effort.

having such a mega powerfull bs sr20 (omfg redtop ohh yessss) you must have been there when it was tuned etc.

im guessing it made sweet f all when they first started tunning it didnt it :) then slowly rose till u got ur million kw @ no psi.

in due time the creases in this project will get ironed out, im sure of it.
