Can someone explain to me what these actually do for a motor? I have seen a few around but have no idea what it actually does.

from the LOOKS of it, it seems that it will have a large body of air instantly available for combstion. However, this does not necessarily mean there will be enough air pressure to create good low down torque. Without seeing internal design, it is hard to know for sure, though I'd guess it is simply a rectangle that bolts onto the bottom half of your manifold. It would then mean the main benefits of the BBM manifold are gone. Without testing it, or even seeing it physically I cannot predict absolute benefits - however I would guess potential quality gains in the top end(provided your car can provide enough fuel to mix) and a loss of low down pickup. Good luck to whoever buys it, and hopefully it proves me wrong due to some internal flow characteristics that go unseen.
Happy motoring.

From what I understand, such an intake design would be best for a forced induction setup? Someone please correct me if I'm off the track.
Might be worth a look in the forced induction workshop threads. Cheers.

this would only work good in forced cars... NOT n/a ones

Happy motoring. ^^^ This post made me laugh. To answer the question though, it is pretty much just to increase the plenum volume for forced induction engines. They dont gain anything from the BBM mechanism anyway.

Abit bloody expensive for a couple of pieces of alloy welded together.

Custom plenums over std intake manifolds do make a difference when it comes to forced induction. Its the actual design that makes a difference..
Go have a look at those crazy VL turbos

Haha haha
Glad to see I could amuse the simple folk. Hopefully it informed the less simple. If you think there is no benefit to the BBM manifold, unbolt it and put on a log manifold. Then witness your lack of low down torque. Those that have said it'd be better off with forced induction are closest to the mark. As I said, good if you want a large volume of air instantly available. But by all means, put it on your car, for the price and lack of real scientific engineering should be a great addition to total power reduction. Enjoy

The ebay seller has a business called "2 high PSI" in moorabbin. I spoke with him recently regarding some other parts. He does alot of turbo conversions apparently. If you are genuinely interested in this part it would be best to speak to him directly.

Enjoy if you read the post he stated the turbo cars dont gain anything from the bbm. Wich is why ford don't fitted the mechanism to the factory turbo engines. you didn't amuse us because we are simple. you amused us because, by what you posted, you are the simple one. and anyone who ever takes your post for gospal is now infact less informed then they were the 30 seconds befor hand. |
