I'm well aware of that. Since Pettit only makes one type of supercharger for the RX8 I think its safe to assume psi is more useful info than comparing cfm.
no not really, if you put to small a pulley on the supercharger then it will spin to fast making to much boost and the result will be less power due to going in the the ineffiency range
no i got what you said im just pointing out that with the 1 size of supercharger you are further limiting yourself whereas there are a tonne of different turbo's of all sizes
optimal would be a little larger supercharger (say 1.8l) for torque and a larger turbo (so it has a bit of lag) for the high rpm power
thats called twin charging and is perfect for a high revving low torque engine
somthing like that should make about 325-375hp and 250-300ft-lbs
The internals of a turbocharger can reach over 1800 degrees. Twin-charging is old and out-dated technology. Far too expensive and not very effective. Also turbochargers produce more torque at lower RPM's for an RX8 than this supercharger does. I don't know where you're basing your numbers since there is no twin-charge system for the RX8. And yeah, I think you're missing what I said. Thats why we're on the subject of non-existing twin-charge systems now.
oh yes i forgot because you can't put anything on your car unless it was intended for said car or it has the word "kit" on the package right???
well i'll tell you what i have turboed more cars than you have owned and none of them had anything out of a box all was custom fabricated
also as for the torque at low rpm with turbo's yes, you are right to a point but with the small displacement and high revving a turbo that would be spooled low enough to make torque would run out of steam and choke out
now if you have a large enough turbo to make use of it's high revving and free breathing high hp nature then it would be verry laggy and be a restriction until it spools
now with a twincharge setup (witch are not much more expensive nore are they more effictive than most think) you could have a large volume supercharger not connected directly to the intake but on the exhaust to raise the velocity spooling the turbo faster for boost at lower rpm
yeah thats true but being as the air is compressed then pushed through charge piping rather than being compressed directly in to the engine the air has time to cool (being as we all know compression created heat) also with a turbo adding a large volume innercooler is not only easier but more effective
im telling you the supercharger is not that way to go
God you're so full of shit dude just shut up. You obviously don't have much experience with rotary engines or turbochargers to say a larger turbocharger that can breath up high will have lots of lag. The GT3071R makes full boost below 3K RPM and will breath all the way up till redline. Don't give me that 'oh i've turbo'd more cars than you've owned' bullshit. TRY and twincharge an RX8. PLEASE. Thats why you're talking about an "innercooler". Stupid ass. Go home bench racer.
oh yeah because i know what im talking about and you do not
if you did you may be like me and own a shoppe that specializes in turboing and dyno tuning
but until then i don't wanna hear your shit
as for the gt3071r making full boost by 3000rpm, i doubt that turbo would make any boost at 3k i did the math if you were using 2inch charge piping and no ic at 3000rpm it would be making 3.8psi
but if you had 2.5inch piping and ic 14.7psi would be avalable at 5700rpm (25psi @ 6500rpm
You don't own a shop. I doubt you even own a car. Ask Tyranical on this site about the GT3071R. His RX8 makes FULL boost (~12 psi) below 3K RPM and maintains that boost all the way up to redline. I don't wanna hear about your imaginary shop and all the imaginary cars you've worked on. Ask the MazdaManiac (who DOES own his own shop) if the GT3071R will make full boost by 3K. You CANNOT twin-charge an RX8 and the stock 13B Renesis CANNOT handle 25 psi. Go back to need for speed pal.
Aww whats wrong I call out your imaginary shop and your fake numbers? PSI doesn't mean anything when comparing different sized turbochargers or superchargers. Thats when CFM comes into play. But when you look at two of the same superchargers, the blower with the smaller pulley and higher PSI is going to flow more air. Don't try to sound smart to recover from your ignorance. Go learn something about cars other than turbos and NAWS. Know the difference between a roller rocker and journal bearing?
first off if you have 2 identical superchargers and one has a smaller pulley it does not mean it will make more power it just means more boost but if you are out of the efficiency range (spinning to fast) of the supercharger the added boost is useless
and im not trying to recover from anything your the one whom has no idea what your talking about and making shit up
and yes i know the difference between a roller rocker and a journal bearing (neither of witch are in a rotory)
ummm, you do know the gt series turbo's are ballbearing, and have almost 2x the flow rate of "T" series turbo's. i have a gt35r on my fc3s, and it makes over 212whp at 3 rpm's, and full spool at 3200 @14psi. the 3071r being a smaller turbo by nature would surely get alot of atmosphere at 3k.... you need to do your math again.
@0to60in16seconds you did what math, dumbass? you dont have any way of even knowing all the variables in the equation, to figure out what RPM will produce certain PSI, from a certain engine. it would require knowing exactly what volume of exhaust gasses (CFM) were flowing out of the exhaust ports of the engine, which is a big variable, changing temperature and ambient pressure changes will vary that alot. you obviously have ZERO knowledge of forced induction, or cars for that matter.
do not turbo a renesis motor! super charge will keep it from being out of the garage. also 3 rotor

How much psi were you running? Nice ground effects btw.
wasp010 3 years ago
psi means nothing
a larger volume turbo/supercharger at 5psi is the same or more than a smaller one at say 20-25psi it's about cfm not psi

at higher rpms.
now if you have a large enough turbo to make use of it's high revving and free breathing high hp nature then it would be verry laggy and be a restriction until it spools
now with a twincharge setup (witch are not much more expensive nore are they more effictive than most think) you could have a large volume supercharger not connected directly to the intake but on the exhaust to raise the velocity spooling the turbo faster for boost at lower rpm

and as for turbo's internals getting verry hot.
yeah thats true but being as the air is compressed then pushed through charge piping rather than being compressed directly in to the engine the air has time to cool (being as we all know compression created heat) also with a turbo adding a large volume innercooler is not only easier but more effective
