R32 GTR with REVERSION ???

[itbmils]

All

I have just finished a FULL rebuild of my RB26 which includes

forged bottom end with N1 bearings

minor port and polish

metal head gasket

N1 Oil + Water pumps

R34 N1 turbos

new split dump pipes + full exhaust

I'm still running in - but from time to time I get stall condition when backing off (throttle lift off)

I notice it most when I'm slowing for a set of lights after running at boost.

I've just read an Zoom (issue #52 page 78) that talks about reversion. This is when air is forced from the turbos back past the AFMs causing the AFM to loose the plot. This results in poor idle and/or a stall. Better BOVs does not help apparently

1: What causes this - my setup is still fairly mild (only running 8psi while running in). It was not doing this B4 the rebuild and I was running WAY more boos1 (15psi)

2: How do I fix this (without the HKS EDIS Pro) - I have a PFC on the way - will that help ?

Anyone ???

personally i think this is the tune.. i just had 34n1s on and car was stalling when backing off adn heaps lumps and i have blitz bovs which made it worse then after tune hasnt stalled once and car is running like new!

running a car in on 8psi? hmm nice... running in == low revs (shouldnt be hitting boost at all) rb26.. stock turbos hit full boost at wat?4000rpm? not exactly revs that a engine being run in should see

Are you running open to atmosphere BOV's? Or plumb back?
