ive been toying with the idea of ditching the twin turbos on the new motor,and just switching out to a centrifugal supercharger.though id still like something i could run high boost with,and i dont know much about the supercharger units.
would a p600b good for a 3.3L v6?

slowfast

No. Idk if you changed since NJFBOA but apparently your turbo was off one bank, then u fixed it "ran a 12" and then ran like 21's just build a 350 and spray it. and be done, dont you have a kid/ on the way?

btw, im not trying to be mean,or anything, and id also apreciate it if you looked down one thread and could awser my question, im cranky

ROFLMAO
i cant belive any of those guys still belive that,there pics posted in the v6 section as i actually built the whole thing,theres no way i could have ever run it off one bank,rofl

and u mean 21 sec @ 24 mph cause i stalled the car lol
other then that i never did run better then 17.8@106 & 17.0@96 & 17.2@90something that day.I dont even rember anymore id have to dig the slips out.That day i lifted at the 1/8th mile every pass melissa has the video of that day and im positive u can hear the car backfiring and banging from the 1/8 mile out.

lol car was just out at the track last weekend with a stock 2.8 not even a 3.1 100k+ miles on it went into the 15's @ 5-7 psi with a race weight just shy of 4,000 lbs thats around 230 rwhp @ 290 at the motor on a stock untouched high milage engine. with the same exact setup i had at the nats - all the ecm/ign problems

keep one turbo and run an sc too. remote mount the sc and run the turbo to eliminate boost lag and keep high rpm boost. the sc is costly and id say keep the money for now and invest it in your business that your trying to start.

lol to costly gf just gave birth to our daughter i figured the supercharger would have less cost to do. i have all the turbo stuff already but by the time i build the headers(stainless header tubing is exspensive lol) and have them coated and all that id have spent alot of money.
i figure i could sell off ll my turbo stuff and just buy a supercharger head unit.and fab up the bracket/ducting and get away much cheaper then finishing the twin turbo setup

Giovannetti

never heard of a v6 supercharger but i might be interested inyour turbo stuff for sale so hit me up with a PM please when you can

il get back to u ina few days,im not sure which direction im going just yet

If you’re building something yourself then personally I’m partial to the eaton blowers… just size it for the power level you’re looking for and don’t look back. The nice thing about positive displacement blowers is that you have power wherever you give it throttle, unlike a centrifugal.

i thought about an Eaton m90 but i dono i just dont like the idea.wouldnt an m90 be less efficiant anyway.id still like to get about 15-20 psi out of whatever i do

A guy local to me is doing this to his V6 mustang. I believe its a Cobra sc.

What don’t you like about it?

As far as efficiency…, well, yea, they have slightly lower adiabatic efficiency than a comparable turbo (I’m not really sure about most of the centrifugal blowers in that range), but they have killer volumetric efficiency, somewhere in the 90% range, which you’re not going to get with anything but an eaton and some of the screw types. Also, there’s a funny thing with them, as you push them harder, force more boost out of them they get hotter (all superchargers do), as they get hotter the rotor clearances tighten and they get more efficient.

Lastly, with the bypass open they put almost no load on the engine, I’ve seen numbers showing that with the bypass open but the engine still driving the blower eatons cost something in the range of .3mpg (properly tuned with actual boost you could potentially see an MPG increase depending on your right foot)

ill ahve to look into it a bit more then i quess, any recomendations on which size eaton i should be looking at for a 3.3L motor ???

M112. You can pic them up really cheap.

the more i think about it the v6 has a nice lower manifold that with some fab work cant have an eaton mounted directly onto

sleepybu

go m112

ive actually been thinking about it, im just gonna keep the new motor turbocharged, except im not gonna install twin turbos like i had originally wanted to.instead im selling of the turbos i do have and am going to be running one very large single

an M90 can be made to move around 500hp worth of air...

maybe in time ill go with an m90, but im gonna have to fab up just as much stuff to use it as i would to do the twin turbos.thats why i just decided to stick with a single turbo.all the stuff im selling will cover the cost of the gt66 and then some.and is gonna be the simplest route to go right now.

actually the hardest thing im gonna have to do is fit the 4 inch downpipe in the car.but ill prolly use a 4-3.5 or 4-3.0 reducer right off the housing to bring the dp size back down to a more managable size

If you figure out how to sneak a 4” pipe past the V6 tell me, maybe it will give me some ideas, I’ve been trying to figure out the same for a V8, and I’m seriously considering cutting away part of the subframe and possibly the firewall.

use a 3.8 motor with a series 2 supercharger on it rebuild the motor to hold more boost...get a 3.23 gear on it and have a fun time my friend put it in his feiro and he ran 12.57
