After we ran the 128 mph pass we weighed the car and the scales showed 3825 with me in the car. Doing the math showed 626 crankshaft horsepower. Only rear suspension parts are Metco lower control arms. Everything else is stock. We did install an eight point roll bar because we figured the car would run quicker than 11.50 after the converter change. None of us expected the 10.88 though.  | Aside from the hard launch, I don't see why 8 psi and 10 degrees of timing is going to be hard on the stock internals at all. KB has been selling kits at 8-9 psi since 2005 and since 2006 they haven't seen an engine pop yet, as long as they are running the KB tune and no other modifications. The positive displacement FI setups have a lot of parasitic HP drain too, so to make the power/times you are making takes more HP at the crank with a positive displacement system, so you should be good for better times than any blown engine on stock internals. I don't see why you would have any problem running at 20 degrees timing with 8 psi and 11.5 AF, as long as your charge air isn't too hot. I would think your tranny, drive shaft, and differential would have more problems with the power (and the launch) than the stock internals.
