Does anyone know the difference between the Toda spec B and spec C cam shafts (horsepower wise).

 

I'm very sorry that I cannot give you a simple answer. There's a radical difference in the high lobes between B and C, and it depends entirely on what else is on the car and how the car is tuned.

If this is going into a street car, then C should be out of question. Some people I know have even installed B's and taken them out as unsuitable for a daily driver.

You've been around for a while, so I'm sure you know that the OEM ITR cams are easily good for over 190 Dynojet HP, and probably right up against 200 HP.

Are you thinking about an H1 car?

 

is that stage 2 compared to 3?
