Went on a rolling road day yesterday morning at Motoscope in Northallerton,Yorkshire here are a few pics and a vid:-
Video here










The tyres on this RS500 had to be deflated as they wheel spun on the rolling road :shock:









My mate Gary from work and his disappointment at only reaching 371BHP.He was expecting 450BHP+!!

 

Buck you need some plastic surgury, and get some contacts so you won't have purple eyes no mo.

But seriously...I don't thin your video works. That's cool that you have days to check your hp, did that cost money? And i didn't realize cars lost so much HP from the engine to the wheels, geez 60 horsepower. What did the factory say your Horsepower was?

 

Hey my eyes are one of my best features
The rolling road opened up for us specially on a sunday..they dont open up for nothing, surely yoiu didnt expect them to?!!...but we got a good group discount.
The factory X types are 231BHP at the flywhhel here and 227BHP for the USA so mine has 10BHP more than factory if their claims are coorect.
AgreeAWD does sap a bit of power.As a comparison the G reg red RS Turbo (like I used to have) (the shiny one) had 179BHP flywheel and 151BHP wheels (FWD).

 

I think Ive fixed it now

 

Its edited and on Youtube now:-

Your car sounds real good man.

 

On the dyno your car will loose 15% of its power in a rwd setup and more if its through an auto tranny and more if its fwd. Given that its an awd car with i am guessing an auto that loss sounds correct. More moving parts means less power to the wheels.

 

Sweet sound buck! Love it bud! Congrats on getting higher HP from factory!

 

yea buck i love the way that exhasut sounds

 

Yep, exhaust sounds great Buck! Love it

Jim

 

it does sound real good. have you done any other performance mods apart from the exhaust. If not, gettin 10 hp to the fly is pretty good

 

Sounds great buck looks great and I missed some video of your red leather mate!
And automotive manufacturers usually rate the car a little lower than actual hp ratings...my cousin works for ford at the romeo engine plant where the svt vehicles are made or engines are hand built and the original 03 cobra was rated at over 400 hp and when some guy had his car dynoed it was rated at less than what they originally released...he ended up suiing and winning the case and walked away after spending 34k on a new cobra a millionaire! So its not uncommon for the hp rating to be higher than stated...love to see someone sue because of more power, as that is the american way!

 

There was an episode of Top Gear where they had to buy a supercar for under somethin like £10k and do some tests with them.
They akll bought different supercars and performed the tests, one of which was a rolling road test to see how much bhp they had current compared to what they should have been when new.
One of them had lost nearly 100bhp over the years[&:]for one reason or another....lol

Hmmm...sludge comes to mind!
