It ended up making 25 to 26psi on gate so there it is. I'll wind in the duty cycle on Saturday and see where it ends up. I'm not that keen to break another rocker so I'll only go to 40psi if it gets there, then turn it back down to 30psi/700awkw for the street to save the driveline a bit. I had a look at the dyno graph a bit closelyer and it dropped 60kw from 5900 to 7000rpm last time so it'll be interesting to compare that if I remember to change the cat. Also the cam timing a a fair bit different so that might change it as well. End of the day I'm happy to run a cat on the street as the car isn't exactly slow, but for racing etc it might be worth running a decat pipe. 1 Link to comment Share on other sites More sharing options...

It's the reason why Nizpro use two of them in their 4" system, that's the way I see it anyway! It made the note deeper or at least that's what it did with my 3.5" xforce system. Do you have issues with roadside RTA's or police down your way? Link to comment Share on other sites More sharing options...

I've got it back to 30psi with about 50% duty cycle and will try and crack 1000awhp in the morning. I'll leave the cat in for now and see if I can get there as is, but will remove it eventually just for the sake of more data. There are police around but if you aren't speeding or doing stupid sh*t they leave you alone. 1 Link to comment Share on other sites More sharing options...

It looks like the turbo has stuff all left in it and the injectors aren't far behind. I'll chuck it on the dyno in the morning but I' don't think it'll make the power I want it to. Hey at least it was a fun ride and learnt a lot along the way. Bigger turbo? Maybe. Bigger injectors? Maybe. Built trans? Maybe. Make the falcon awd? Maybe. Anything at all? Maybe. Time for a beer? Definitely! 2 Link to comment Share on other sites More sharing options...

Im suspecting you’ll loose a bunch under the curve and might not gain the flow up top for the sacrifice... but that’s my educated guess can’t wait to see the graph ! plus an overlay of peak before cams vs after would be great viewing Edited 28/05/21 09:18 AM by JETURBO 1 Link to comment Share on other sites More sharing options...

It's looking like the turbo can't flow enough to take advantage of the cams which was kinda to be expected. At any rate it's still a mental thing to drive, and being a 6 speed auto with antilag you can get it on boost pretty quickly when the need arises.
