45mm DCOE weber big enough for 13BEP?
Hey Guys,
In my Series 1 (SA) RX7 have a 13B Extend Port with a really high flowing exhaust (ask my neighbours) but I still run a stock 12A Nikki Carb unfortunately. Is it worth upgrading to the 45mm DCOE weber? I can get one tormorrow with 13B manifold and water injection for $150US.
My car is running super-lean, it made 107rwhp on a Dyno Dynamics dyno (not in shoot-out mode) and then when they took the air filter off there was to much air getting into the engine so not enough fuel got in and it only made 95rwhp.
How many rwhp can I expect with a good air intake, a new fuel pump and the 45mm Weber tuned on a dyno? When you push the car above 5000rpm it stops accelerating as fast and just stays at the same rate to about 7500rpm, sounds wheezy to. I've heard the Webers make it more drivable because they're only 2 barrel over the 4 barrel Nikki.
What does this mean? More low-down torque?
