Was at it today,

Hybrid T28 Turbo
Full Mongoose De-cat System
GG Stage 2 Chip
1.3 Bar Boost
Fuel Pump
Fuel Pressure regulator


243.3BHP At 5422rpm

271.7Lbf/Ft At 3610


So just beucase you car has the graham goode 305 conversion, doesnt mean your anywhere near 300bhp, bit disappointed in that result. But its a brand new rolling road and has been calibrated within the past 7 days to within 1% so its right.

mine has a graph for 298bhp 320lbft @5890rpm and is a very similar spec.... there rollers may not be too right???

ryan_belfast

They're rollers had be calibrated in the past few days, and were within 1% accuracy.

Funny tho, as i raced an FQ320 Evo 9 and was basically the same speed as it.

Richie Russ

Does seem quite low for 1.3 bar, assume that the car is performing as it should do, air leak maybe ?

ryan_belfast

The car is running like an absolute beast, as i said its sitting with near enough FE320 evo 9 and M3 CSL's.

Dave Henshall

is the figure the RR gave at the wheels though....?

ryan_belfast

They said to me the figures were "at the fly"

Dave Henshall

the only true measure is to have the engine out and have it on an engine dyno, you should have a go in a similar spec car and see whether you think the figures are comparable, personally, i dont get hung up on quoted figures, its all about how it feels and drives IMO

TurboNutter

If you say you can keep with Evo's and M3's (which i don't doubt) then it's gotta be making more than 243... An Evo 9's gotta be a similar wieght to a cos, so with nigh on 80 bhp more than your quoted 243, it should leave you for dead... Strange, if it's an "@ the wheels" figure, it would make more sense..

ryan_belfast

Thats what i thought turbonutter, if that was the at the wheels figure, it would work out around 298bhp with a 20% loss in transmission.

adamski frst

i recon you gotta be kicking out the same as mine cause mine flies mate and i was toying with a M5 the other day even had to brake round a roundabout as his back end was out...

Damo V

IMO even 300 brake wont stay with an M3 CSL, the driver mustve been a poof if you did

Dave Henshall

ryan, ive just had a horrible thought, if your boost (re the other thread) is that high in 5th and you are keeping up with evos etc, the RR will generally only load the car up ni 4th gear as 4th is usually 1:1 of most cars so they can get a more accurate measurement of the car, if the car isnt producing as much boost in 4th, the power willbe down, but when u get on the road and loasd it up in 5th and run that higher boost - you may well be runnnig lean - and lean cars generally tend to go like holy fook - usually just before something catastrophic happens like a pistons melts or a valve drops in

persoanlly, i'd go easy with her until you can get her fuelling ckecked all the way though teh revs, gears and boost levels, literally a 100 quid now may save you 1000's in the not too distant future

Thanks for the advice dave, ill get it set up this week.
