Ahhh mo worries. So you still have no idea what us causing the TC lockup problem?

Tap, crackle, pop

Not a clue old mate - hopefully will find it whilst out though ...

Those boxes are sent to test us!! You got an error code?

Wouldn't know if they are even recorded now mate - replaced the ECU ... worth a look I suppose though ... I mean, what harm could I possibly do to the new ECU map??? lmao

See if this makes sense to you - 1.06 rear, 0.5 inlet on the compressor side, with a 60mm Trim. Makes no sense to me!!! lmao. Apparently that'll not loose too much bottom end, but give me heaps more up top and let it rev out longer through the curve so it doesn't plateau around 3000 rpm ..

All that married up to a straight through 3" system (already got a 3" dump pipe, but didn't change the 2.75" exhaust at the time).

Sure does!

1.06 A/r rear, that's referring to the rear exhaust housing size. The bigger the number the bigger the housing and the bigger the housing the bigger engine you'll need to produce enough exhaust gas to run the turbo efficiently.

0.5 inlet, that's the size of the compresser housing. Not a big important factor..

60mm trim, that's the size of the compresser wheel. Bigger wheel the more volume of air it can move.


Your issue with the massive flat spot at 3000rpm is that little turbo running out of puff. The exhaust side of the turbo isn't big enough to produce enough air volume to hold the set boost pressure. The 1.06 rear will sort that out!!

Thanks a million champion!!! I owe you a beer coz I somewhat have a better understanding now!!! Only somewhat though!!! lmao

Its all about flow and efficiency that size should do a nice job.

Thanks mate - I hope so ...

You could run like the superior truck did 350hp at the treads with a 100hp shot of nitrous which was actuated by your foot getting to the the throttle stop on the floor

Ummm ... no thanks ... lmao

The bigger turbo, more efficient setup should see me drag another 50 or so rear wheel gee gee's out of it apparently, and that will see me over 240hp at the rear wheels ... enough for now!! lmao

That would only be running mild boost to wouldnt it say around 8psi?
