wastegate + centrifugal Blower > Positive Displacment
 

Anybody read the article in MMFF August pg 174 "A gateway to street supremacy". Looks like a good idea of adding a wastegate to a centrifugal blower.
I posted the article below, I use to have a turbo and wondered why no one had done this before now and Im glad someone has done it. Last page of article is on 3rd post so scroll down.

Thats awesome, but too bad it wont work on a draw-thru setup

Aw man, Magazines take like two extra weeks to get here.

I got mine about 10days ago.

yeah i read that article. they use the wastegate as a pressure regulator
I really dont understand all the technical stuff.\
thats whole issue of MMFF has so many forced induction article.
would have to say the V-sick article was the best turbocharged v6 657 hp runs 9's

I've been saying this could be done for years, and have been doubted time and time again - even by vortech engineers.

I did find a guy who did it on Corral a few years ago on a SN-95 cobra but also went blow through.

I'm curious if they could just bleed the air back to the inlet of the blower after the MAF and remain draw through ?

I had planned to do it once I get the 5.4 in.

A smaller pulley will raise the amount of boost which is not good as you may need to use race gas or get forged internals on a stock engine. With the wastegate you can put on the smaller pulley lets say a 20psi but set wastegate for 15psi. You may say whats the difference between a 15psi pulley and a 20psi pulley with a wastegate set to bleed at 15psi, arent they both 15psi. Yes you are getting 15psi in total but the with the smaller 20 psi pulley you will be getting full boost (15psi )at a lower rpm and maintain the 15psi all the way up to redline.

Not only that, but who in their right mind would expect a 15 PSI vortech to get up and going as quick as that car does.

Everyone would say ""oh yea 15 PSI - at redline, its only 6 at launch while my cobra makes 17 as soon as i hit it......" ha ha ha - suckers ;)

That is one of the main reasons I plan to do this - sandbagging like a mofo.

I also like how the vortech boost comes on, but not how long it takes. I dont want my boost INSTANTLY, but I also don't want to wait 3,000 rpm for it. Being able to dial in the boost and where it comes on hard is key on a drag radial car.

True and what I like is since full boost is not instant you will not have traction issues on a street car.

Bingo !

I know the guy with the v6 real good. Hes the guy who tuned my car back in october. Real good guy and his v6 is even sicker in person! It sounds nasty! I couldnt believe it when I saw him in the magazine. Didnt know he had got it down to 9.80s last time I heards he was low 10's.

its one bad ass stang that can slaughter a cobra

turbos need those BOV's (wastegates are technically on the hot side of the turbo) so they don't get the dreaded impeller reversion. Blowers don't "need" such things because they're mechanically driven. Turbos are driven by gas, which can be overpowered by built up boost in the pipe, especially as you dump the gas and hit the brake... that sort of thing blows up turbo's.

Blowers are physically linked to the crankshaft so they don't have the same capacity to see high output tube pressures at impeller speeds cause a reversion.

Venom nailed the best use case for a BOV on a blower car. You make sure you don't overboost it but your boost comes on real low. I'll still take a twin screw first.

I actually picked this one up, just for this article over the weekend.
