    Power boost valve

    Hi


    as you all might know i have an astra 1.6 8v which i wanna make quicker


    i've done the deristrict airbox mod and am waiting for my veccy c pipe and adaptor to arive at vauxhall. The de restrict has helped my engine a lot, it makes a better noise and theres no engine choke when i put my foot down.


    anyways, i've been offered a boost valve, its one of these
    http://www.fuelsystem.co.uk/pbv.htm

    i've been offered it for 40 quid. Is it worth it??? how hard are they to fit??? would they be compatible with my 1.6 v8?? oh sorry i meant 8v

    Should i buy it???. I get flat spots when accelerating.

    can it harm the engine???


    Thanks

    p.s. does my car have efi?????

    It is just an adjustable fuel reg. Normally rising rate aswell.

    Only worth it if your at that state of tune where u need a bit more fuel without changing injectors.

    As Sean said, absolutely pointless on an engine such as yours. They are useful if you have twin carbs or a fuelling setup which the standard fuel pressure is not high enough. Requires setting up properly on a rolling road.

    You may get a small increase in BHP but not much really. Can do alot of damage if not setup properly. My friend put one on his XR2i ages ago and it overfuelled badly. Caused alot of damage.

    IMO you would be better off saving some cash up and getting an exhaust system (the remus straight through pipe and a backbox) and then a remap. However, it is at the end of the day a 1.6 8v, and you wont be able to resell the map, and the exhaust are pretty cheap new, so you are pretty much throwing your money away by tuning it!

    BUT I can understand the need for power - so good luck! Can you fit bits and bobs from nova GTE engines? Maybe tune it up a bit and get it on twin carbs like this astra on eBay:

    Would sound nice and be a surprise from an Astra. Oh and EFI stands for Electronic Fuel Injection, which I am pretty sure your car has.
