Here are some videos from a few years back. This is my B14 SEL making 360whp on 16psi on the old log manifold. Running 205-55r15 all season tires. Stock suspension.
I'd say for 360whp it is holding traction very well. The second I put on the hyperco suspension I noticed a decrease in traction, most likely from increased camber. But this shows that you can hold traction (at least in 2nd) with a decent amount of power with the right suspension tuning.
