all i have to say is good luck getting it running.
What i am going for is a reliable 250 HP with 10.5 compression (91 octane gas). Maybe 8lbs of boost with a decently built motor?

maybe 10-13 psi boost but it will rip pretty good as long as the tuning and managemant are in place. And accordtheory, anytime bro, anytime

either way, sounds likea fun setup. Light boost, reliable motor, decent tuning.Originally Posted by AccordEpicenter
Oh and im with you guys! One of my professors always ends class by saying "Always group yourself with those smarter than you." lol.
for some reason, and i think accordtheory can vouch for this, there is a huge power increase from 6-7 psi to 9-10psi... at least it seems this way

the butt dyno gets more excited when you get close to double digits ;-)
lol dude.

yes, it makes my ass twitch

yeah i think the super turbo thing would be a wank to get running right
but would be fun to have a go at
talked to a speed shop a year or two back bout a low pressure turbo system and they reacon that 200hp would be easy at the wheels with less than 14 psi and be reliable
sound right to any one out there?
Sorry, guys..sometimes I have a really weird sense of humor. They say it's good to be able to laugh at yourself though, right?
It can be done, but I've never seen it done in a way that is very good. I'd say if is possible to set up a supercharger system that held onto it's efficiency across the powerband, then the turbo could add onto it nicely.
What normally happens though is that if the supercharger is set up to move enough air to boost at low rpm, it's efficiency falls off at higher rpm. So when you combine that with the power loss from driving the supercharger off the crank, then what you end up with is the supercharger + turbo being less efficient than just the turbo.
However, if there was an electric clutch on the supercharger and a valve set up to bypass the charge air past the supercharger once the turbo spooled, that could be highly functional. That's probably a patentable idea right there.
I wonder how that would compare to a sequential turbo setup.. (oem supra, rx7 too, I think) That can achieve boost at low rpm, and good top end power, although it is rather complex, with all the valves and controls required.

i think thats almost how that nissans idea woked
might just google it and come back
found it
hopefully this works

that should get you a page on the wee nissan march super turbo
mid to high 7 second 0-100kms from 930 cc
what you think that set up on a b20a would do
mid 5 sec0-100 km at a guess
I really like when I come up with an idea and then find out it has already been done exactly as I described, and works well..nice for the ego.
But not as much as if I was the one making the money off it..
for those of you that are going to TRY to supercharge...once you succeed you can buy one of these from me! lol
came up with it yesterday
accordtheory, wow, just wow. so the supercharged 3.8 has the worst powerband ever? u must be kidding. i happen to have one that runs faster than oh, any car on this site. save for the motor swapped drag only cars, mine is a street car. it ran a 12.65 on street tires on its OLD setup. that thing peaks torque at 3200 rpm and makes more torque than i think ANY production honda motor. it doesnt have the greatest top end but it has a bunch of low and midrange. i pull consistant 1.8X sixty foots on street tires, who here has beat that? thats called TORQUE. and a G6 would get SMOKED by a GTP. the heads blow on the 3.8 and it has a weak cam. it runs 6psi non intercooled from a shitty roots blower and they still run mid 14's stock with 3500+ lbs and with an auto. $300 in those gets u 13's and a few grand gets u 12's, easy. that is a great engine, y has it been on wards 10 best engines a bunch of times? because it works very well and is one of the most reliable engines ever built. u should get your shit straight before u post your opinion as fact.
Yeah? You just shrunk my ego. So much for the earlier post about that nissan..
I was just posting my experience, fuckhead. I knew someone was going to get butthurt after I said that, but I don't care, it's true. That car drove like shit. I went to the local auto mall, and was test driving cars. One of them was a gtp. I like gtps, I used to read about what people were doing to them, including everything on one of the first sites/companies to modify them, thrasher engineered performance, but that one was not very impressive, to say the least. I don't know about Your car, but a stock G6 would beat That one. Could I build a gtp that would kick ass though? Obviously. But I'd do it with a centrifugal setup, or a turbo system. I don't know about the tranny on that car though.
Just to clarify, gtp nutswinger, I was using that car as an example to criticize the blower, not the rest of the setup either.
But now since I'm on that subject, if you like pushrod motors, good for you. Whatever. I just wish honda would build larger motors the same way they build their k20s, so everyone else would shut the fuck up.

i agree, if honda made a 5 liter V8 with vtec that would kick ass. but they dont want to hurt their precious fuel economy with a V8. and yes i am a bit partial to muscle cars/pushrods, love the sound. secondly, the trannies (GTP's) do suck ass. the stock ones barely hold up and the blowers do suck. but up to 6lbs a roots blower cant be beat. after that, its heat/inefficeincy city.
dunnit just piss you off eh dude?
a mate and myself built a push bike twenty years ago that we had grafted front and rear motor bike suspension on just to see if we could do it, and whats the big craze ten years later?
by the by, Anyone know how a DC Sports header would hold up to 10-15 PSI of supercharger? It will be coated by Jethot for 1600 degrees, but what im really worried about is the welds holding up...
It would probably hold up okay, but it also probably wouldn't be ideal for power with the supercharger. Endyn did research on this a while ago, and found that a header with shorter runners and a 4-1 collector (not tri-y) made more power. Just to cite that as an example, not saying all setups will show the same, obviously. But I doubt a dc header is anywhere near optimal. (Does it even have a real merge collector?)
i really think that at 15psi its gonna be a real bottleneck in the exhaust, and if youre gonna run 15psi boost id say a 3" exhaust is ideal, and i wouldnt run anything less than a 2.5" mandrel bent. Supercharged engines like large diameter short runners in a header it seems
429whp 362wtq A20 TURBO. A20T>*
well the primaries are pretty short, but the secondaries are kinda long. The pipes themselves are way skinny, and the collector diameter is only 2 inches. I tend to agree with you on the bottleneck issue, though. Im not sure though, i think i really want to stay under 10 PSI. Its all up in the air, i may make a supercharger thread where we can toss ideas back and forth.
