It is like comparing superchargers, an F3 Procharger is way more efficient than a D1, but then you'll have guys saying that a D1 is more suited for engines making x amount of horsepower and it's better on the street, which is nonsense. Guys now are running turbo wastegates on the intake tract of their centrifugal supercharger setups so they can control the amount of boost being applied (as opposed to relying on pulley size), then stuffing the largest supercharger that they can get on there and pullying it up. Doing that both maximizes and controls that power throughout, making the whole menu on Procharger's website of varying compressor setups being completely irrelavent, which is why you will never see them come out with a wastegate for a supercharger, because then you would only see one type of supercharger being sold, the biggest one....
LOL!!!
prove to me factually that a bigger/pullied supercharger running a wastegate on the cold side of the intake wouldn't make more boost earlier, more boost in between, as well a more boost later in the rpm band with a wastegate controlling psi. I am more then willing to have a conversation about this because i know two guys that have done that, one with an f3, and one with a ysi, and they average way more than anything smaller could ever produce...
the wastegate is not relevant in an application where a drag car is properly set up to take as much as the blower will put out and and get down the track in the limited rpm that the car runs in. In this application you'd think you would have a better chance of being correct, but you're not. There are plenty of 7 second small block cars out there that will slow down when adding a big f3 over an f2. As i said in my previous post on this topic, it's due to a number of things, rotating mass being one of them. Your great wastegate idea doesn't seem to take into consideration the amount of power it takes to turn a large blower, which is a lot.
oh my goodness, are you serious? Exactly how much more resistance do you think applies there...?
i see the same thing here, very often. The compressor wheels are huge. An f3 can be anywhere from 123mm to 139mm. A small block will run faster with a 123mm than it will with a 139mm because of parasitic drag. The 139mm is just too big for a small block. Also the larger the engine, the more hp the car will put to the tires with the same 139mm. A 565ci with a 139 can not compete with a 706ci with a 139. That's why it's so hard to keep the blower rules fair for everyone. They aren't like a turbo engine where a small block and big block can make near the same power with 88's.
just for laughs i copied and pasted this post and sent it to procharger tech support. I thought for sure the response would be hilarious. Here it is, verbatim from their tech department:
"the person that posted that has no clue what they're talking about. How much
sense does it make to put a blower that takes 500-600 hp just to spin on a
300 hp engine? Your car would be slower than it was before the blower was
added. People do install blow-off valves to control boost, but in order not
to hit a point of diminishing gains, they still start off with an
appropriately sized blower. "
street lethal keyboard racing, you are a fountain of knowledge
