I cringe a bit when he pushes on the hood....
and buddy started mumbling when comparing the 2 sheets....

459rwhp VS 479rwhp

Nice

 

I think for this to be 100% accurate you would need to test a larger sample of cars. I'd say maybe 10 of each model year, also it may make even more power once it has a few more miles on it.

Pretty cool though that it is rated at only 10 more HP but it puts out 20 more to the wheels

 

Maybe I missed it but they didn't say in the video how long each car had been sitting. The 2010 or 2011 could have been suffering from some heat soak.

 

I wrote to JT and asked him how many miles on the clock for each car tested.

Nice find Red Jay. Thanks!
