Hi there
Sorry for not so many updates, the car has being used every day without fail, poor M3 and Clio not getting a look in, this thing is so good its just bonkers good! Never before have I had a car that can fire out a corner or roundabout like this, its so frantic and such a case of just hold on I often find myself chickening out even though the car is begging for more, the ability is uncanny.
Anyway a few Mustangs buddies were having a free dyno runs at rotary revs which are pretty much Europes no.1 rotary specialist, but they also specialise in tuning the NA and super charged Mustangs. Their dyno is fine for power runs but does take a lot more time to setup as its more a tuning dyno, its a first for me as it was a hub dyno, so no damage to tyres etc and their dyno cell is like a fridge, very much like Powerstations old setup cooling wise, very effective. We only did one power run anything to prevent any heat issues, then waiting ten minutes and did another, first run 509 and second 511, both at wheels.
The dyno graph:
Having heard stories of 458's not making claimed 562HP I went in expecting as little as 440WHP and maybe if it was a good one around 480WHP.
So to leave with 511HP wheel power I was over moon, especially as we did not rev until limiter for simple fact of not wanting to hit the limiter.
Other cars that ran:
Ecoboost with Cobb tune & intake: 295WHP
V8 Mustang with MY18 Intake manifold, Kooks Headers, CAI, Exhaust: 440WHP tuned by MAP
V8 Mustang with Roush Stage 2 Supercharger: 625WHP
Mac's 666 Yellow Beast: 661WHP (Spark plugs fouled)
Mickey's Gen2 Whipple 3.750 Pulley: 681WHP tuned by MAP
Clives Gen2 Whipple 3.6250 Pulley: 722WHP & 566lb/ft at wheels tuned by MAP
Tomorrow a very special yellow Mustang is attending, that should be close to 900WHP, gunning for 1000BHP crank.
Absolutely over the moon my car made the numbers it did, of course I've put close to 1000 miles on it now, all Vpower99 which maybe helps, this puts it around 585HP crank, which may explain why its as quick as Mac's Mustang pretty much, even on a roll, as its got plenty of power, low weight and short gear ratios, plus DCT helps a lot. Be interesting to see what it gets at Pod, its certainly quite a bit quicker than the SVR once rolling.
Some more pictures from the day:
The tuner and dyno operators were impressed with how flat and strong the torque curve was for what is a highly strung engine and said that much power NA must be a sheer joy to drive, which is absolutely is.
So great to know the car is very healthy, backs up my thoughts of it feeling strong, I drove a total of four 458's and the first and one this felt quicker for sure.
