My motor is starting to get a little old, and may go out within the next year or two (showing a few bad signs, lately? Oh well). I'm going to be working basically two jobs this summer, so I'll have some money stored away in a "car fund" in the case that anything happens in the near future. I'd like to make 300+RWHP out of my supercharged six-port motor, just wondering if you guys think this setup could make that kind of power:

Half bridge 6-port engine
4x720cc injectors
10-12 lbs. of boost
Wolf 3D V4 (being installed as I type this,

I know I would probably want to change out my drivetrain (don't know how much a GTUs drivetrain will hold), and I know I won't get terrific gas mileage, nor will my car smell nice. I'm just wondering if I can break 300rwhp on a supercharged rotary engine. Maybe I would need a custom air-water intercooler and about 1 bar of boost?

Actually, I should probably wait to see what kind of power I'll make now, with a stock port motor. Just speculating...

supercharged, 300hp? dreamsville? yes


Well maybe. Honestly the camden kit puts out only 180hp to the wheels, sad but true. It uses an older type of supercharger, and possibly the kid who bought it here, bought the smallest one.

But with a Peripheral port, plus your standalone, and MAYBE (not sure) bigger injectors+pump+SC, you could do it.

BlaCkPlaGUE

hrm, actually wait, with the PP you couldn't use the roots charger, scrap that idea

1) Define "supercharged". This could mean the use of a centrifugal turbocharger, centrifugal belt-driven supercharger, Roots/Eaton type belt-driven supercharger, Lysholm type belt-driven supercharger, or any other forced-induction device or combination thereof.
2) Do you intend this car to drive on the street?

snub disphenoid

Proper peripheral ports make over 300rwhp without a power adder, but still I could not do the peripheral port, nor do I have the money. The guy that made 180rwhp didn't had piggyback fuel management and a mostly stock exhaust. I have full standalone and true dual exhaust (yeah I know, too much flow for my car right now). I think I might be able to get more than 180rwhp peak.

1) Perhaps the Camden twin-lobe roots-type supercharger (inefficient, I know). I might take the time to adapt a Whipple 2300AX twin-screw compressor to the existing kit, though.
2) Yes, I'd like to be able to drive the car every day. Right now it's my only car, and it will probably have to be for about 4 more years.

It sounds like you are grasping aimlessly.

I recommend that you grasp Corky Bell's "Supercharged!" book before you start the project. It's available through most online book sellers and local book stores.

With the right turbo, 300rwhp is easy. Exactly the same is true for superchargers. You need to get that Camden kit out of your head.

Wanna explain why?

snub disphenoid

Well, if I'm ditching the Camden kit, I might as well just do a half-bridge high-comp. turbo car. Probably would be cheaper and easier than building a custom lysholm setup.

Yep, too lazy to buy and read a book, I'd rather bug other people. So far I've got some good responses and I might actually spark a debate.

bingoboy

someone has done a whipple FC with a claimed 320ish(?) hp on the forum....damnit i can't remember who.

BlaCkPlaGUE

When I was refering to dreamsville, I was refering to the camden roots supercharger. If its a centrifigul one, that would be a different story. You can actually use an intercooler with that setup and get some more air in that engine.

Have U Got That Thing Dynoed Yet??????

snub disphenoid

No, man, the wiring harness is being made today and tomorrow, and maybe by Friday they'll have the full-throttle tuning done with, so I can get you guys some numbers.

bingoboy

or if you are DIY'ing you can go down to your local exhaust shop and get a few pipe bends w/flanges made and run an intercooler with anything you want. if you plan to do any real customization yourself camden probably isn't the way to go.

RX7FROMCAL

well , i wish u the best on the dyno man, cant wait to see what urs does , have fun!!!!

RX7FROMCAL

did u ever get the dyno??? its been awhile since ive heard what ya have done.

That would've been me. 348hp to be exact.

S5 6port block, TII drivetrain, mild streetport, microtech lt8

Dyno numbers yet? :|

My Paxton blower is finally getting installed on my FC this week.

To get what you want out of a supercharger would take an act of god
second choice supercharged V8 (or 3-rotor heh heh heh)
i wanted a supercharger so bad when i first started looking for more HP
now probably just going to do the N/A turbo conversion
Pianoprodigy - i saw those pics of your FD, so beautiful, i wish i had one

so can anyone explane why a good roots blower is unable to make 300 RWHP? *tip* I don't wanna hear the phrase "well not enough boost" or what ever. Also, don't type that there is not way to plumb in an intercooler, cause that is retarded anyway. You can make anything happen if you read enough and try hard enough and spend enough money.

Evil Aviator

A Roots blower could quite easily make 300rwhp on a 13B with no intercooler and a lot of money. The problem is that not very many people want to spend that much time and money on a car that is not streetable when they can easily upgrade the turbo and fuel system to make 300rwhp and actually drive the car on the street.

I know I'm new here but I've designed a custom supercharger kit for the 1.8L/2.0L Mazda protege engines using a small Powerdyne BD-600 and BD-11a supercharger. We obviously dont have much in common but one thing that is universal is the efficiency of the powerdyne blower and it's VERY low charge temps. This is one of the main reasons my supercharger kits have been making so much power with so little boost. On early Haltech F10X base maps I was able to make 60whp on only 4.5psi.

Now with a centrifugal blower you don't have the increase in torque like you would with the roots-style but you also don't have to worry as much about shredding tranny parts.

I'm not real familiar with how a rotary engine will handle boost but the powerdyne will make peak boost at redline. If you were to say run a 7psi pulley on a 7k rpm engine you'd make appx 1psi per thousand rpms. This would be very easy to dial in and tune with proper EMS. This usually makes it much safer.

also it wouldn't be entirely difficult to make any sort of mounting bracket and charge piping for this engine as my FC has PLENTY of room under the hood. You could end up with a VERY powerful engine for around $2500 or so.

This is Jameswade2002, not Amishboy.

Okay, so where do you get the idea that a 300HP turbo car is going to be MORE streetable than a 300HP supercharged car??? WTF? Why would anyone wanna spend $2500 on a supercharger that will produce 2psi at 2,000 RPMS? When your spending that much on an engine, why would you care about shredding trannies. The other question is what do you consider to be streetable? I don't really consider a T04R to be a streetable turbo, ofcourse if I have 7psi of boost at 2,000rpm, then you know, I can always let off of the gas. Its always spooled. If your going to tune with a wide band and custom fuel management, what is turning up the fuel in some places. Its a hell of alot easier to tune a liniear boost curve from a roots blower than it is to tune a big turbo. All of this bench racing is pointless anyway, if you wanna go fast, just spend the money, do it, and have fun. don't try to do it on a budget, don't try to set deadlines, don't take a fix it and forget it attitude. All of this is retarded, and I'm really bored.

The problem with roots blowers, is they simply suck at efficiency. That and where are you going to find one that moves a decent ammount of air, that's relatively cheap? (The m90 1.3/lrev isn't really much of ****). As for centrifugal, the problem is, most of them are designed such that the rotary just doesn't fit in their peak range. (such as the vortechs), most of the vortech's we just kind of sit inside of the surge-limit. But anyway, this arguement isn't much good, for the cost, a turbo is almost always going to be faster. And if you argue about the flat torque curve and boost lag, get a properly sized turbo and learn to drive!
