Doc, is the car in your sig yours? I remember you trying to sell your vr4...

Stock rods don't like torque, and I think a T70 will make torque. They also don't like a poor tune. They don't break from RPMS, they break from torque and detonation.

Follow the mototune breakin.

The clutch issue goes 2 ways in my opinion.

If you are running an organic disc, breakin is important. If you are running an aggressive non organic disc, its not important. A performance clutch that is not organic should hold the first time you slip it hard and let out.

You will be running low boost while you seat the rings so don't worry about the clutch either way! You are not doing full RPM blasts on your first hit.

True, this is why it is good to read all your directions. Usually it will say a specific break in pattern if there is one, every company is different though.

The thing is, many performance clutch companies just claim that you need to do it so they can have a reason not to warranty their product...even if its not necessary.
