I will have a look around and see if I can get my hands on a profec. Don't really want a manual boost controller
PRofec - OLED Electronic Boost Controller If I buy it from the American Greddy website for $525 i'm only paying £325 so I might be able to stretch to that...
plus shipping, plus import taxes, plus rape from the Royal mail. It'll be £500 or so landed in this country.
What are the real differences between them apart from one being electronic? And adjusting boost under the bonnet or in car?
One costs you next to nothing, takes 5mins to fit and set up and does the same thing every time. One costs a few hundred, can take a while to fit and fucking ages to set up correctly, and usually is a pain in the arse and gives more to go wrong. I see no advantage of being able to adjust boost levels in-car.
haha where the 'like' button. yeah but my leccy boost controller has high and low settings. like I have ever used the low...
Why not just pick up a second hand boost controller, the profec B spec 2 go for £150 online. Another advantage of EBC is you can set gain which will help spool the turbo earlier.
I did have a look on eBay and they where around that price. But I didn't know if they where fake or not. And yeah quicker spool would really help as it's going to be more of a street car then a full comp car
Boost usually tails off at the high end because the turbo isn't capable of pushing the quantity of air required to maintain pressure. Not much a boost controller can do about that.
Why? If the boost controller, be it manual, electronic, or fairydust powered, stops air getting to the wastegate or actuator until full boost is achieved, spoolup will be a little faster (well, the gap between 'some' boost and 'all' the boost will be, the rpm turbo starts making boost at won't change, it's not magic) than with a pipe straight to the actuator/wastegate with no boost controller at all. It will be a little faster than a manual bleed valve too, though that will be faster than nothing. TBF, on most cars, unless the turbo is big, the gap between 'some' boost and 'all' the boost is small anyhow. Only way you're gonna beat any of the above is with a CO2 powered system, which will prevent pre-turbo backpressure from pushing open the wastegate a little before full boost, which happens a lot (and is what twin port actuators and twin port wastegates are there to help prevent if plumbed in correct, though not as good as a CO2 boost control.
The gizzmo ms-ibcs are a good piece of kit and gizzmos aftercare is second to none. I liked the fact it's a controller and real time gauge all in one. As far as I was concerned, I had to run a vac line through the bulkhead for a gauge if i went with a manual controller anyway, 2 more wires to a solenoid wasn't much more hassle. Its been a fit and forget item on both vehicles i've run them on. Got one on my modified diesel navara now and it's controlling a heap more boost than you would be on a CA with zero issues.
Thanks for the reply. Seems it's a hit or miss with the Gizzmo's. Been getting mixed reviews on them. This pushes me more towards the electronic gizzmo though cheers
