So I finally got around to getting my car back on the dyno to test out the gains with the Billet Power Blocks installed.

The highlights are:

• Peak vs. peak gains of 3.9 hp and 8.9 lb.ft. of torque on an otherwise stock car, on the stock tune (171.5 hp @ 6550 rpm and 142.4 lb.ft. @ 6,250)
• Gains literally EVERYWHERE up to about 6,800 rpm
• More torque down low, with a 6.5 lb.ft. gain vs. the old torque peak at 3,210 rpm (140 lb.ft. @ 3,000 rpm vs. 133.5 lb.ft. @ 3,210 rpm)
• Torque dip substantially narrowed (though still present), with a big surge in torque around 4,200 rpm (about a 14 lb.ft. gain here)
• Gains of 6-10 lb.ft. from 5,000 - 6,250 rpm

You can read all the details and see the dyno sheet (same car, same fuel, same dyno and operator, but about 7 months apart between my baseline stock pull and today's runs) on my post in my Member Journal here.

In short, I would HIGHLY recommend the Billet Power Blocks to anyone with a 1st gen BRZ/FRS/86 who is staying NA, and especially if you're going to stay otherwise stock.
