Disappointing Shelby output?
Discussion
I love the Shelby but was very disappointed with the performance as is my mate. There is no way a 500 bhp car should go like that does.
I drove a car with a claimed 483 bhp a few hours later and even though it was a bit lighter, the difference was big. (F430).
It honestly felt like 500Fez and 400Mus, not 483 and 500.

The Americans are finding the GT500 dynoes reasonably true and much depends on dynoes which calculate the power anyway.
Even the Americans have spotted the GT500 is the automotive equivalent of Christopher Biggins. This is why the Roush Mustang with 80bhp less still took 2 seconds out of the GT500 round the Top Gear track on the same day. Nearly 400lbs is a big weight penalty and like carrying two big hairy blokes in the back of your Mustang GT all day.
It pays to research your car before you buy it. The sad thing is your mate probably paid over the odds for the GT500 too since they're still selling for a premium to Americans who think they're going to be a collector's car.
None of the American tuners use the iron block engine in the GT500 but then the point of the GT500 was always a base to pour more power in. Ford are already spotting the GT500s problem and this year are launching the GT500KR with 540hp. Tuners are already working on 6-700hp GT500s.
However, for my money, I'd take the new Roush 427 Trak-Pak edition:

Heatsoak is also a massive problem on this car , speak to a decent US tuner and he will tell you the best way to wring proper power figures from the GT500 is to leave the car in the shop overnight , stick it on the roller sin the morning , running for a few mins to warm it through then take your run, if you turn up off the street with a hot engine , stick it on the rollers then let the engineers fart arse a bout for 10 - 20 mins , strapping the car down and setting everything up you will get figures way down on what the engine can really produce and more to the point what it will get on the open road.
Our car drove like a car with well over 600BHP , got the dyno figures to prove it , but on later runs when the engine was roasting and the MAS was hot enough to cook on power figures could drop by 10%!

It comes back to the same thing though. Emotional purchases. I think the C6 Z06 is an ugly beast (and I have loved all Corvettes and owned 2 before the C6 ended my desire for one) and of course only has 2 seats so is strictly not comparable and not an option for many people who need those back seats.

fair point, not yet had one of these in , was trying to get a Ron Fellows Special over but was beaten to the last one! Somehow ended up with a Dodge RAM SRT-10 instead! Momentray lapse possibly - tho i cant wait to have a blast in it , Hennessey have had a little play !
I had one on my list funnily enough but 8 mpg isn't funny.Another good point , its even worse when you have a BP102 station within driving distance!! Put that in the Mustang once, try as i may , i could not get the pump to stop on .00 , the damn thing just clocked round so fast! before i knew the best part of £50.00 was gone and i only had a few litres!
yes , thats what i meant , sorry about the grammar! realised a comma would have been appropriate after the event!
thats not bad fuel consumption then from the SRT QC, as we not had one before iv no experience , obviously the vehicles dont cover much mileage whilst in our hands but we do like to have a go of course - perk of the job i guess!

Given the fuel tank issues, you did well to get 50 quid in at all!
