My question is how stout? All I want out of the car is no less than 250whp, but 300whp at the most. Do yall think a forged build is necessary?
Have you ever rode in a turbo miata? With 6psi, from a role on I was running with a 99 GT mustang till 100mph. That is probably 150-160hp with my setup.
300hp is possible, but I would want to build the lower end.
I want to run 250hp myself. But if I only get 220 I'm cool.
The motor is good for 12psi without lowering life, after 12psi you start lowering the life span. The maintrain is good for 250. After that things start to get weak.
Remember the car only weighs 2000 Lbs. The new mustang has around 300hp probably weighs 3500-3900lbs. And it will run pretty hard.
Think what 250 to the ground in a 2000lbs miata will do.
These cars are not the tire ballars of the V8's I've had. But they accelerate hard. And if your spinning, You're Losing Time.
If your wanting a stock GT mustang out of the miata, you can do that with 8-10psi. No where near 250-300hp.
Anyway, how much is in your budget for the build. That will define the build more than anything.
