Cuanta potencia aguanta la caja de cambios 1.8cc?

[terrorik]

Hola

Escribo por un tema sin respuesta en un foro vecino, dicen que ustedes son de exigir mas los coches jajaja

Actualmente mi Miata nb2 01'' vvt llega un kit Supercharger mp62 con una polea diametro de 62.5mm, carga 10PSI con un peack de 11.3 PSI. Estimo que debe estar generando unos 195 rwhp.



Quiero un poco mas de potencia y planeo comprar una polea de SC 60mm o 58mm en TDR.com

La pregunta es:
-Cuanta potencia aguanta mi caja original 1.8cc de 5 velocidades? (con kit de embrague 949racing + flywheel)
-Que polea me recomiendan comprar, de 60mm o 58mm, y porque? Lei que la de 58mm podia patinar a altas rpm, sera efectivo?

El kit de embrague lo compre en 949racing, es Ceramico (Ceramic 4 puck - Sprung Hub) mas volante alivianado (flywheel)

Aca esta la tabla, destaque mi configuracion actual.

Guideline at miataturbo.net is around 250 hp on the 5 speed, 350 on the 6 speed. Some of those guys are running serious boost on the 6 speeds. Be advised you'll need to change your rear end, as the 6 speed is geared lower than the 5. Stock is 4.3:1 on the 5 speed and 3.9 on the 6, which gives overall just about the same top gear RPM.

5 speed clutch is said to start slipping before 200 hp. I don't know how much the 6 speed clutch can handle, but I doubt it'll hold up to 250 hp.

How long did your 5 speed last at 250 hp? If and when I go turbo, my goal will/would be to keep boost low enough that I can keep my 5 speed. 250 hp is just about where stock rods start bending, and that's not a playground that I want to play in, either.

The rumour about MSM transmissions being stronger is that Mazda advertised the gears to be plated. However, people who've taken them apart have seen no difference between them and the non-MSM 6 speeds, so they may have all been plated. Last I read, there was no consensus as to whether the MSM box actually has an advantage over other 6 speeds.

lo anterior es aplicable, tanto para turbo como supercharger?

La potencia es potencia, da igual como se consiga.
Aunque tu/mi compresor robe potencia al motor para hacer que gire y no se consigan la gama de potencia de los turbos, 200 hp son 200 hp da igual si se consiguen con compresor, con turbo o con un motor atmosferico.
