I have a dual stage boost controller (turbo X's) and will be hopefully getting it in the car soon.

What do you people think is better (taking money into account) a dual stage boost controller or Electronic Boost Controller? Cause i am thinking of selling and buying a EBC due to the "spiking" issue... How does this work?

yup.. thats the one.

EBC just is more efficient in opening the wastegate at the exact PSI, meaning that its not likely to let the boost creep up too much past the setting you give it. Generally with an EBC you can safetly run more boost and hence more power assuming everything else is working ok.

See'ya:burnout:

aside from the consistency factor, having the in cabin control is the best. you wanna give it a hit all you do is turn a knob and the car is totally different. it rains, you turn it down and avoid your rear end snapping out (to an extent)

I was told that when your car nears redline spiking occurs and can make the boost level raise heaps. If this happens can it stuff up your turbo or engine?

Spiking occurs when you change gears.. not towards redline.

eg..

you have set your bleed valve to 10 psi.

you take off in first and red line it.

you shift in to second and slam on the gas. the boost flies up and for a slight moment, it over boosts to about 12psi and then drops back down to 10 and holds it there..

the point when it hits 12psi for a fraction is what you call BOOST SPIKE.

this is due to the way that bleed valves control the wastegate.

Electronic boost controllers provide a more smooth wastegate operation and therefore you don't get SPIKES.

has nothing to do with overboosting at red line....

I have an Apexi AVC-R and havent had any problems with it.. You effectivly get 3 settings as you get two programmable and of course off... So effectively you can set it up to low, med and high ( that is what mine is set to do )

Very happy with AVC-R... No Regrets...

But at the end of the day its your choice... :P

arent u also able to set boost to rpm on the avc-r?? i was initally considerin gettin the blitz i-D which is smaller and a lil cheaper but to get the extra functions such as temps a/f power readouts and setting boost to speed (which i dont see the use of) u have to buy the blitz power meter.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
