If you fit a boost controller,is there a need to fit an after market boost gauge as well,just that it seems the normal thing when seeing other modded cars,is it really needed,as i would of thought the boost controller will only go as high as its set to,and takes care of things!,lets say i fit a Blitz SBC-iD and Power Meter iD,would there be a need for a boost gauge,and(not to sure on this)a aftermarket oil gauge,as i think the Blitz can do this allso,just wonderd!:confused:

Yes its best to see what boost you are running at.

The boost controller will do its best to keep the boost to the set level and does a good job of it. But they are not perfect at keeping the boost at a very constant level and is alway adjusting to keep it there.

 

However if the electrics used to detect the boost are slightly out you could be pushing more boost than you think. You program for 15 psi and you could actually really be pushing 16, 17 or 18 if the boost control is not working at 100%

 

The extra boost gauge is just reasurance that the boost controller is doing its job correctly, and because the gauge is directly driven from the turbo pressure its a lot more accurate and safer way to measure it than electrical sensors which can get worse over time and send false data. The boost controller and the gauge will probably always show the same pressure, but if 1 day 1 of them is showing a different vaule something is not right. It could be the gauge but most probably, the boost controller has gone wrong. And that £40 boost gauge could have saved you a very expensive rebuild.

 

Plus they look really cool :D

:) Cheers Stuart,:D

by the way the clocks you have do not seem to be the same ones as on the site http://www.sca-racerally.co.uk/revotec.htm have they changed the design!

A boost controller, once setup correctly, will hold your boost perfectly! However, to set it up properly, you need an accurate boost guage. Mechanical guages are just as unreliable (if not worse) as electrical ones. The trouble with the twin turbo setup is it doesn't allow the auto learn functions to work on the controllers. This means you have to set the gain etc manually instead of just turning the guage to the desired boost. At this point you really need a good boost guage to see whats happening... Hope that makes sense..

 

CheerZ,

;) Cheers Andy,so would if it was you fit a electrical one over a mech one,Tony

Yeah, tbh I would always go for the electrical one. I don't like the thought of bringing pipes from the engine into the cabin. Just IMHO of course ;)

 

CheerZ,

Tony I got ones called PRO LED ones. They dont have any pictures on the site of them but they are listed on the list of stuff they have. They are the only place I could find on the internet that has them. I found them on http://www.speeding.co.uk where they are £2-3 cheaper, but they had limited choice. I ordered my oil pressure from there and its free delivery. But after ordering I read their site saying it make take 2 weeks to arrive :mad: wish I got them altogether instead of getting them from different places and trying to save a few quid.

 

The PRO LED gauges are all mechanical. Except the boost. I have never seen a mechanical boost, but its only a small tube that blows a small portion of air.

Like Andy I prefer mechanical, cos I too dont like the idea of boiling hot water and oil flowing inches away from me and my radio. Electrical one are just as acurate as mechanical ones, but its worth replacing the senders every few years. They will only cost you £5 each or so, and not £80+ for Nissan senders.

 

Stuart

:) Thanks for that Stuart,and any idea where would source the senders from,cheers,Tony

The PRO LED gauges come with senders with them. The boost gauge also comes with all attachments you need, brass bits, nylon hoses and stuff.

 

When you want to replace them I am sure that they are all just universal ones. Why reinvent the wheel? In Nissans case cos they can charge 10 times as much for it. :D

 

On thing I will suggest you need is a T-Peice for the oil pressure so you can keep your stock one on too, of you get an oil pressure. They are £5 ish again, and will allow you to plug both your new oil pressure sensor in and you old Nissan dash one.

 

Stuart

:) Cheers mate,much appreciated,Tony

One last thing. For the water temp, you may have to get a hard pipe made up from Smithy or take you car to a garage to put the sensor in. You will have to drill it into the pipe yourself, because none of the adapters fitted the stock sender hole and you cant get an adapter for the water. You could do it yourself if you wanted I dont thing its that hard really, but I cant see a garage costing you much as it will only take an hour at the very most to do.
