Dear SK
I have read with interest your articles on the Independent Boost Controller (IBC).
During the Christmas holidays I bought Performance Electronics for Cars to read while lazing on the beach. (great read for those interested) The controller caught my eye and I duly purchased one with the hand controller on my return from holidays. Unlike you, mine is still sitting in the cupboard in my workshop unmade!
My turbo let go early in January, I took you advice and got it GCG hi flowed and have just finished reassembling and installing it after cleaning out impellor bits from the FMIC and replacing the clogged up CAT. The car is running again but I haven't really given it a run yet.
What caught my eye in the original article was that the boost solenoid in series with the actuator, as did you. A couple of question for if you don’t mind.
I run a Wolf plug and play and it has an internal boost controller which is programmable on bleed every 125 RPM. I thought I might convert it to a series type still using the Wolf. Any thoughts?
I then read your articles and I must have missed the IBC is controlled by load on the injector. (a few zzzzzs on the beach) I like the idea of 110K with or without boost and more engine response controlled by the throttle – less lag?. I used to have a 260Z with triple Webers and I miss the instant throttle response of a NA engine. Maybe I should disable the Wolf boost control and use the IBC instead? (My original idea after reading the article)
I also like the idea of flat boost at 7000 RPM. My experience with the old turbo was boost fall off at max RPM. Is this a function of the controller, turbo or just controlled better with the IBC?
My last question is Fail Safe. What happens if the IBC fails, solenoid stays closed, max boost?
Cheers Rob
