New to the Lexus world. Just purchased this new 2015 RCF sport on Monday and wanted to see what power this thing makes. Went to a dyno jet today and these were the results. Next mods will be intake and exhaust system

Nice pull! Do you know what brand of dyno it was?

Those are great numbers! With TVD or Torsen?

Really good numbers. However, they need SAE correction applied to them. They might be lower with SAE correction factor applied.

It was probably 1.03 or 1.05 saw there is an easy calculation for that

It's not an RCF Sport...just an RCF

A267mm

So there all the same just one has different diff and carbon roof?

When corrected for dyno type and drivetrain losses, how does this compare to factory claims?

A267mm

Factory claims 467hp assuming 15% drivetrain loss looks like right on point

nice numbers

how come previous dynoed RCF showed lower numbers?

Have most dyno been on a dynojet also TVD or torsen?

Theres been a mixed bag of nuts from 350 to 375 for stock base runs... various between TVD or Torsen didn't really matter..

On Dynojets most Lexus "guys" like to show their graphs SAE corrected with smoothing set to 5

It's supposed to be the best wway to show power measured at the wheels..

I've come to realize over many years of dynoing at different shops, the results will always be different.. From car to car, state to state & dyno machine to dyno machine..

I can post dyno's (with optimized parameters) that show our RC F test car making over 400 WHP or 40 hp gains with just an exhaust upgrade..
But its Not REALISTIC, so why do it..

Not a dyno operator, I will put the car tomorrow on another dyno to see if power is same, but like u say maybe I do have a fast one 😂😂😂, we will be making a new exhaust next week and back on dyno if it gains 40whp I'll be happy with that 👍👍👍
