N/A Power!!!
Who here, on this board, has the highest hp from a N/A 12a or 13b (carburated) for that matter. I'm interested in knowing, because I plan on getting the most out of the engine, and would like to know what I could do without going overboard on porting. I'm more interested in knowing the output of the 12a, but i wont discriminate if someone has a rather powerful 13b.
If you just know someone with a powerful 12a, please post that as well. Thank you :D |
i know somone that has one with 270+hp 13B carbed... well hes picking it up prety soon :D if all goes well for him.
|
I've seen dyno sheets of a race car with 260hp with a fuel injected, heavily ported 13b. The torque and hp were very peaky and not very streetable.
|
Yeah, that's what I'm talking about!!!! But those monsters are probably Peripheral or Bridge ports :eek: Any that are just running a streetport??? Peeky hp rocks!!! :D
|
My friend was getting 285 hp out of a bridge-ported OLD STYLE (dual distributor) 12A using a downdraft Weber. Sorry, I don't remember if it was a 48mm or 51mm. The motor was in a 165 mph RX3 that was raced in GT3 class.

I think Crispeed has worked on a 12a street port with twin webbers thats putting out about 260hp !
it was in a thread a few pages down from this one |
the car im talkin about has a holly 650 ... RB headers straight pipe to a super trap... heavily SP i am prety sure racing trans i dont remember who made it... it was origionaly a circle track race but was takin out of the races and had it slightly moded for the road ( suspension n shit) its running about 267 HP i think 13B but the guy had it carbed. thing sounds freakin amazing it burries the rpm tach i believe it revs to around 13k rpm ...without destroying the engine. obviously it has a lightened fly, and all those goodies.
|
theres someone on this board with the user name '680rwhp12a'. i assumed it was a joke?
|
He claims its true, and has posted dyno charts, but I guess noone believes him. I don't know why, as I haven't been around this forum long enough to get a feel for different members.
If you go to: http://www.mazdacomp.com/customerscars.html they list cars running 10s, 11s that are NA (although only in a couple cases do they specify NO2 use). That's a lot more than 275hp, but they're drag cars, and probably not what this guy is looking for. |
I know your wanting 12a stuff but I was at RX7.com while they were dinoing a 13b, p.p, fuel injected, with Jacobs ign(non turbo, no nos)............298hp at the rear wheels!!! Whats that make at the motor............320?????:drool:

and he claims 680 RW hp, meaning the engines making 7 hundred something. thats really hard to believe, but if its true thats insane.
