Hey guys, ive recently been trying to extract a few more kws out of my turbo td42. Had the injectors done,pump timing,intercooling and then i started asking about fuel aneroids,and thats where the confusion started. I spoke to quite a few reputable turbo specialists, there were two in particular, one said ''its a complete waste of money! in some aplications we actually take them off!'' and the other said they wouldnt even try to tune it without one. I ended up going with the later and i couldnt be happier! Got an extra 10kws at the wheels and much smoother power delivery. Just wondering what your thoughts and experiences are with these?
Cheers Den

Boost compensator confusion?

one of those things bar room debates are made of lol.
basically there is no way you can run max fuel on a high boost motor without one. some people get away without one with careful use of the throttle but most are not that careful, the end result can be cracked heads or trouble with the cops (depending on local rules etc).
most small turbo diesels have them as standard. afaik the older direct injection (not really my thing) often don't but then there are often tuned lean to avoid over-fueling.

The maximum fuel your pump can deliver is not altered by fitting a boost compensator. So maximum power isn't altered.
What is altered is smoke and off-boost EGT's. The boost compensator when tuned properly won't give you black smoke or high EGT's before the turbo spools up.
The more boost you're running, the bigger the difference will be. With 10psi or less it's a take-it-or-leave-it type of thing.

from what i found when i was hunting around the guys that tell you not to use them dont know how to tune with properly with one.
mine makes good power (gu pump 80 series internals, modded injectors and 15psi) and doesnt pump much black at all unless you flatten it.
the anneroid made it heaps cheaper to run and is actually more responsive down low and when crawling because it doesnt over fuel till the turbo spools

well put. much better way of putting it.KiwiBacon wrote:The maximum fuel your pump can deliver is not altered by fitting a boost compensator. So maximum power isn't altered.

tho i would reckon even as low as 6lb would be a take-it-or-leave-it type of thing. it all depends on how high your max fuel is.
Mine was $750 fitted and dynoed.Im running 12psi.beretta wrote:Sorry for slight hijack. How much for the aneroid and how much to fit does anyone know? Bout to turbo my GQ running potentially 13psi of boost. So this thread is excellent for me too!
