Sorry to bring this back from the dead but i was messing around with the calculator a little. To run the times that the Puerto Ricans are you would need a little over 1750 HP according to this calculator.

 

That's so funny Allen.

Now I have to make about 800 more hp than I thought.



Anyway all motor power takes a lot of experimenting. It's a big challenge. And for those that do not believe and all motor Mazda 13b cannot make close to 400rwhp then too bad because I've seen what Kilo's car makes at the wheels and it's a lot more than the best MFR motor ever made at the flywheel!

It takes a lot of hard work and determination to be at that level and no one is going to just give you the combination for free. Trust me on that one.

 

Hi Crispeed,
I know it has been years since the last post here, but can you give me/us
any information as to getting just 300 whp from a naturally aspirated 13B.
I have a 13B semi PP with the secondary intake being bridgeported. The housings are from a series 5 turbo engine and the rotors from a series 4 N/A engine. I ran into trouble with the front rotor touching the centre plate badly at around 11 000 rpm playing on the track. I must admit the whole rotating assembly has been ballanced, but at 99 I swoped the turbo rotors for a matched set of series 4 N/A ones. This could be the main reason I have this rotor and bearing failure on the front rotor .

So please send some advice our way as well
