Very good top end, very average down low... But that pretty much is every turbo on a RB20!
Got bored with 260rwkw so decided to do a E42.5 mix. 50% BP98 and 50% CSR Sucrogen E85 (we don't have any E85 here on pump in Perth)
Comparison of BP98 and E42.5 (same boost level at 22psi)
I had this issue with my T04z...
Couldn't get them off, nor could my mate who is a mechanic. I ended up taking into turbotech on great eastern highway and they did it for like $10
Well worth it, they are a bitch
You do realise that methanol isn't nitro...
I love when my stereotypical hatred for Americans arrogance is always confirmed whenever I converse with one
Wait, what?!?
Also have another graph with 467rwkw that overlays the first graph untill it carrys away top end...
I do agree through that a harder boost ramp would be a huge improvement
Boost control as others have mentioned is shocking...
Ditch the Power FC boost control kit as it is junk, either install a Turbotech bleed valve for $35 which will work very well or fork out for a Blitz Dual solenoid (spec r or IDIII) so you can have multiple boost settings
It was time for a bit of a driveline beef up, looks pretty much stock under the bonnet as well
Front mount and Pod filter = 260rwkw

Watch out with that fuel rail... just primed mine and it pumped out fuel between the rail and the end fittings from very poor machining
We ended up filing off the end, then wet and dry sanding and then using a hydraulic rubber/metal washer to get a good seal!
