HP per cubic inch? What the hell are you talking about?! Fine I'll take my 110 cubic in motor that puts out near 200hp vs. most 300+ cubic inch 8's that get 250-300 anyday.
|
to the wheels by the way.
|
So by that most domestic 300+ cu. in. V8's should put out about 550-600hp.

Besides LS6 is where it's at... :thumbsup

whats the difference between a 800hp supra and a 1200hp one? they both runs 12s. Your dyno sheet wont add up to reserection at the track. Most domestic V8s have been putting out over 250 since 1993.I know the LT1 was rated at 285hp and that was back in 93.Thats plenty enough for some punk to kill himself in.There was a documentry on on speedvison that most import brands have been overrateing HP since the mid 90s somtimes up to 20hp more then they should be rated. |
I always wondered about those 13B's. Never actually worked on one before but stock the RX-8 only getting 18MPG city..lets say 20-21 MPG mixed driving is horrible for a car that runs high 14's!(correct me im just guessing on this one)
I was getting that exact same gas mileage in my old Stealth with 320hp running low 14's stock. and the car was almost 4000lbs with AWD too. |

As for building a 4 rotor, go for it.... Mazda did build a 4 rotor which I believe was what won le mans in 1991. Anyhow the toughest part is the ecentric shaft. But if you to a search on google or yahoo they have pictures of the shaft for the 4 rotor. If you seach yahoo austrailia search a guy named hitman with a yellow first gen rx7 he made his own 3 rotor using 13b parts. |

i like the drag if my redline is 6500 and i can pull off 11s thats fine by me. |
Obviously for you guys its a matter of opinion. No use arguing. Personally I like the rotary because of its compact size it can be mounted really low so it makes the car less top heavy for better cornering. The RX-8 motor lacks torque its a shame they didn't make a turbo version. Anyway. The car that won the '91 le mans was a mazda 787B and it had a naturally aspirated 2.6litre 4 Rotor making 700HP and 600lb of torque. Not to mention its the ONLY japanese car to EVER win lemans and the only Roraty to win lemans. So even if you don't like the technology. Show a little respect.

Funny that "imports over rateing HP" and "rotaries" came up in the same thread. Mazda Overrated the HP in the RX-8 BIG time and had to offer refunds to everyone that got them. LOL.
All I have to say about rotaries is this, how many V8, 4 cylinder Turbo swaps do you see in an RX-7. How many Rotary swaps do you see in... anything? Alot more of the first, a lot less of the second. |
HP per Litre and HP per Cu. In. are essentially the same measure so what point are you trying to make.. you still compare horspower to a form of displacement.
