Judging by the difference in restrictor plate size (smaller by 1/16" for Toyota for the Nationwide cars at Daytona this year, IIRC) and the performance seen on the track, I'd guess the Toyota's have about a 15-20 HP advantage over the non-R07 Chevy SB2 Nationwide NASCAR engines. The restrictor plate costs about 10 HP, yet the Toyota's were able to pass SB2 powered cars that use a larger restrictor plate. The Chevy Nationwide R07 is on a par with the Toyota Nationwide NASCAR engine in HP. The Chevy Nationwide R07 uses a restrictor plate the same size as the Nationwide Toyota. Whether this all will hold true with the Sprint Cup cars remains to be seen.
