204mph in 1/2 a mile

 

Rod has really got his work cut out for him now!

Would love a go in it

 

The americans are on a different level when it comes to this sort of stuff , the fastest cars to run in the UK would struggle to make top 10 at the Texas mile.

 

I guess there's a hell of a lot more places to do it over there too. Although there's never any traffic on the M6 toll road!

 

Thing is over there is a set mile distance, if they used the same over here is would surely open up more places where runs could be held.

 

Now thats fast.

 

Proper fast. Very cool car

 

Rapid... The yanks don't mess about!

 

Going by the video time he does 257mph in 26 seconds!

And thats bogging down at the start too

If I could do that my 8 mile trip to work (if it were a straight line!) would be in under 2.08 mins!

 

I dont think Rod has ever intended to have the fastest V8 5+ litre car TBH mate.





Epic car, mental performance, just goes to show that if you want to build a fast car the best thing to start with is something designed from the outset is a fast car.

 

thats how the rich boys play

silly silly fast car

 

Also it proves just how much more power you need at the top end to gain a relatively small amount of speed.

Rod's Sierra circa 800 bhp - top speed 218? IIRC
This GT circa 2000bhp - top speed 257

 

And the GT does it in a standing mile.

This one's even faster

266.9mph

Stevie you are a walking book of knowledge.

Get back on jimmer and crack a few whips! LOL

 

Proper buff mo-fo car !

 

Nice

 

Not if you are doing 266mph & still acclerating. less than 5 secs extra on the throttle & then death in the carpark at Brunters .
Will be approaching 120m/sec at the bottom & maybe you need to stop .

 

If it was run over a mile it would be a lot safer than currently though Rod, you must concede that surely?

Also would mean it was more about what the car accelerated like rather than being able to buy extra distance with better brakes or by taking bigger risks etc so would make it fairer.

 

For the vast majority of course.

 

Yeah nice. Just shows what a 5.4 can do

No replacement for displacement.

 

Most decent runways here are close to 2 miles ? So that would leave 1mile for accel, and 1 mile for decell, both very safe for a mile

Although looking at the Texas mile info and on google earth. Seems it is only 1.5 miles in total. So 1 mile for accel and 0.5 mile to slow down
I certainly had no issues in that distance at Woodbridge, although at some events they do use the rougher extended areas as well which takes it closer to 2 miles total.

Bruntingthorpe seems to have around 1.9 mile total ?

But I agree any challenge should be over a fixed distance. And a mile is a good benchmark.

Although dont think I'd like to be shutting down from 250+ in only 1/2 mile lol Although looks like Santa Pod has only a 1/2 mile shut off too.

 

Certainly not Woodbridge or Brunters. Both measured by Myself at 1.7 miles & that includes the rough area at Woodbridge. Woodbridge is however much safer as you can go off into the light shrubs at the end & survive, you cant do that at Brunters. Brunters was 1.9 miles before the end was shut off 12 years or so ago

Its great to hear about these 250mph cars but in the Uk only 4 cars have cracked 215mph in 1.5miles. . We are pathetic over here i accept.

 

Measuring on Google Earth, both seem to be around 1.9 miles.

It all boils down to money though. The cars achieving those speeds have hundreds of thousands thrown at them nevermind the initial purchase price. The GT is obviously a very good platform to start with too.
2wd, mid engined so it will have good traction, no doubt pretty good aerodynamics and an already good engine.
Probably the best value car out there for mile attempts.

 

+1
Just about summed it up there dude

Ian

 

the engine in the car is quite easy to get the power out of, and not as expencive as u would think, the 5.4 and 4.6 modular ford engine is so tunable, and unlike over here were cosworth bits cost an arm and a leg, the tunning parts aren't to dear.

the ford GT dry sump block is (alloy with dry sump setup) $2500
rotating assembly from MMR rated at 2500hp $4000
i bourght a pair of complete genuine ford GT heads for the engine i'm building for $2000

if u allow the same amount of money again maybe a little more for the rest of the bits i'm sure u could get an engine producing the power this GT is running, i'm allowing $15-20k for my engine, but i'm going supercharger not twin turbo, as said, i have the heads already, and also i have the ford GT inlet that take 16 injectors, the 16 injector GT inlet is only $300 delivered and is a work of art.

the inlet kit.


my $2000 heads

 

You bet your arse they can be tuned.

1500hp from a stock block. Although that GT will have the 32v heads like yours.

Mines using the 3v head. Still allot of power can be achieved with bolt on parts.

Just bought a Roush charger kit for mine out of the states for under $1k. Thats gonna go near 500hp without going near a rolling road
Stiegmeier' "Snakebite" charger that could go near 1000hp with a forged bottom end and some trick bits.

That's all just weekend warrior stuff!

What power are you looking for out of that Stang unit?

 

looking for 1000hp at the wheels, not sure what its going in yet, might go mid engine 2wd using the GT gearbox, or else it will go 4wd using a modded dodge viper gearbox, 1000hp is about the limit for supercharger, above that u need twin turbo

here is a video to show how tunable the ford GT is, just a twin turbo setup in place of the supercharger and a remap, 1012hp at the wheels

http://www.youtube.com/watch?v=7kgK2DlEhZw

 

Aye well you can supercharge to any power but it takes to much power to power it

Takes 500hp to turn a top fuel charger.

Always confuses me RWHP that the US uses? What's 1000 RWHP at the fly wheel?

Oh yeah looking forward to the build.

 

Take all dyno numbers with a pinch of salt.

Take US rwhp numbers with a big pinch of salt.

Take UK guesstimated flywheel numbers with a big pinch of salt.

Often US rwhp numbers are as salty as UK fwhp numbers.

Ignore them all and see how the vehicle performs on the road/track. That doesnt lie.

 

So what you saying fella?

The only true flywheel HP figures can be measured on an engine dyno?

 

No. The only true test of a cars performance is measured in the real world. Whether that be the road or track.

Dyno's whether rollers or fixed dyno are a tuning tool. Nothing more or less. Increases in numbers mean the tuner has improved performance, a reduction means they have more work to do
How much that improvement is will be reflected at the race track. Or not.

 

stevieturbo's last two posts should be stickied on here, and referred to when these BS dyno threads are started.

 

The last engine I seen on an "Engine dyno" (Cat C32 V12) made 1012hp on average over a few runs.

You guys saying this is wrong? Just a estimate?

 

They arent wrong and they arent universally right either.

They may be correct for that dyno at that particular time. Are they comparable to others ? That's harder to answer.

And that's what too many try and do. Compare their numbers and make sense of them.

Compare performance not pub/dyno numbers.

 

got to agree with Stevie the usa whp figures are more like our fly figures as some of the power claims on engines with brand turbos with certain psi boost could never be achieved here ,so it must be our dynos wrong
as said on the track is the real test

Stevie surely that old brick could go a bit quicker over the mile with a few tweeks lol

 

here is a video of how tunable the standard engine is, factory long block with 27psi, 9.66 142mph in the 1/4 mile

(the lumpy engine u can here is something in the back ground, you only here the mustang when it revs for launch and is quiet and smooth)

I bet Rods car would be a lot faster if it was as aero as a GT!

Whats amazing about that second vid is the car has a stock bottom end! I'm not sure what a GT costs, but i'd imagine if you want to go crazy fast its probably one of the cheapest ways to do it. Doing the same in something like a Sierra will cost you heaps more money.

Also on the Brunters debate.

It'd be great to limit it to a mile, its actually a "sport" then. It could be compared to the states, held a different places etc etc.

 

I dont doubt it

But dont see it happening anytime soon. It's a bit of a silly speed to be doing. I dont think the original 2.8i spoilers were ever designed with it in mind.
