ok guys i wanna get 400BHP to the Flywheel these are my calculations lemme know what you think
b4 i start its a 12A carb obviously its in the 1st gen section and 2nd i email camden superchargers and for the 7" blower the says it gives 230hp with some bolt-on's so im expecting atcually 100hp from this blower but it dont make no sence to me, check their site ull see for the sceond gen it makes crappy HP anyz ill move on, now b4 u bash and talk crap these are estimate HP numbers so its just a brain storm 105---Stock HP ---Modification 5-----Fan Removed 5-----electric waterpump +waterjacket mods 15---Alternator + Main Pully + AC pump and AC 8----Ignition+ 3rd spark plug Total 6 plugs like the R26B 20---lighten rotors + Eshaft 40---1/2 bridge port 3-----side plates lapped 60----carb+exhaust+Filter+hood scoop 261 Total to the Flywheels 100 est from camden blower 361 BHP Now i say because i lighten all my parts (rotors eshaft and so on ) i might be able to squeez out 25 more HP Total comes to 386BHP with regular fuel and Hopefully with 106 octain closer to 400BHP what do you guys and girls think? https://www.nopistons.com/forums/pub...IR#>/boink.gif https://www.nopistons.com/forums/pub...IR#>/boink.gif huh huh |
why dont you street port it and put a turbo on it?
|
i would say don't lighten rotors and e shaft and put that money to better use in a turbo kit, you won't need to rev up high enough where lightened rotors are a must

I say you won't even be near 300 rwhp with a supercharger. |
Don't do the 3rd spark plug. Of course if you knew why the R26B had them, you'd not even consider it anyway. https://www.nopistons.com/forums/pub...1047683664.gif
For those interested, the R26B employed a late trailing ignition system where all three plugs would spark at the same time at TDC or whatever the advance was set to. That's it. All three totgether. I won't go into the HP vs torque vs fuel mileage vs compression loss issue with the late trailing holes in this thread. To keep it simple and reliable in a racing environment, this setup made sense. Of course we can take advantage of a late leading spark which accomplishes pretty much the same thing and can be nearly as reliable if not moreso. WAY WAY less expensive too. |
honestly if I were to spend the $ that your talking to do all that I'd buy a 13bt or a brew and and transplant it, it would save some work and be easier to get the HP you want, just a thought https://www.nopistons.com/forums/pub...IR#>/smile.png

how would you go about doing the third plug anyways lol?

ok, I don't know much at all about making power out of a 12A, but what I DO know is that the power figure you get from a forced induction setup (a.k.a. super/turbo charger) is relative to your naturally aspirated power figure.
So if the supercharger you're talking about DOES give 100 horses to the 12A with just a few bolt ons, it should give even more after you do everything you talked about. Fact: Given that there are no restrictions in your whole setup (intake/exhaust flow, fuel, etc.) 14.7 psi of boost from a super/turbocharger should roughly DOUBLE your power (this is universal, meaning if you have 7.35 psi of boost, you should have roughly an additional 50% of power). So therefore (again, without any restrictions) this Camden blower seems to be making somewhere around 14-15 psi (though I highly doubt that....) and therefore should DOUBLE your power figure of 261... Meaning you could theoretically make 522 flywheel hp. But again this all comes down to restrictions of air, fuel, etc. AND particularly the fact that your Camden supercharger probably doesnt make the power you stated, unless one of those "add-ons" is a bottle of nitrous. But good luck anyway.... Joe P.S. If anyone understands the situation more than I do (i wouldnt be surprised) then feel free to correct me, I dont know this from experience. |

You can have x turbo running 20 lbs of boost and it can ONLY FLOW so much CFM. Now say you have a bigger turbo at 10 lbs, it could flow much more air then the first, so you make more power. PSI does NOT equil flow. -bobby |
true, and i meant to list that as a restriction (air flow). but still, as I understand it, (correct me if I'm wrong) a bigger turbo flowing through the same size intake ports/manifold wouldnt really make a difference, it would just add more pressure (psi) as the passage narrowed. So yeah, my math was given that you have a properly sized compressor.
