wow this is an old thread of mine when I was new to this lol just tells me how much I've learned over the year
I guess the next question is, how long do you expect it to last before it requires a complete overhaul and does the drivetrain put up with that kind of power?
Toon's setup is making 450 wtq, and has been for a few years. Only drive train mod his has is an IPT valve body upgrade.
Torque and instant shock loads are what break things.
Increased RPM, and hard launches (drag racing) will put the most stresses on components.
How long will it last, all depends on the driving habits, maintenance habits, and compentency of the owner.
When making high HP over stock, 2X the output of stock is a good rule to follow. I prefer to go by the 2X the wtq.
When increasing the HP high over stock, it is best not to increase the RPM to much, without upgrading the internals.
