Are knackered Subarus faster?
I was being pedantic, seems to be a lot of generalising going on...most of it horse $hit if im honest

Some info from another siteL
I am thinking about the 0-60 times. I am wondering how the new 6 speed tranny and the gear ratios will factor into the 0-60 times. My current 02 WRX can easily hit 60 in 2nd gear (red line in 2nd is 68 mph). According to my calculations, the 04 STi should require another gear change to hit 60 (red line in 2nd being 56 mph).
I know that there is plenty of speculation about 0-60 times, but most seem to say mid-high 4.x If this is true, and an additional shift is necessary, it would equate to some pretty dramatic increases in accelleration! Any thoughts or input?
Variables used in calulating:
STi: 1st gear 3.636, 2nd gear 2.375, final drive 3.9 red line 7000.
WRX: 1st gear 3.454, 2nd gear 1.947, final drive 3.9 red line 7000.
Tire diameter for both: 24.97

Potentially a pointless exercise to rev to 8k though if you hit peak output at below 7k rpm as most street Subaru engines do. No doubt you will hit 60mph with increased rpm limits but if it takes longer (if time is important) due to lower engine output there's no point.
Obviously engines that have been suitably modified to shift the peak output higher in the rev range will benefit from higher rpm limits, but for most cars your rate of acceleration (0-60 time) will be in decline the further past peak output you go.
Of course most of us realise that none of the limitations to human achievement imposed by the Universal Laws of Physics generally apply to certain WRX owners, but that's what makes them 'special', isn't it

Finishing work in 15 mins. Will test out the 2nd gear 0-60 after warming it up, will post honest results in about 1 hour.
I have a sneaky feeling my pressure is down to 0.8 from 1.2 however, might be simple case of bad batch of fuel and rest ecu.

Also, what car have you got? Matt has the worlds fastest Newage WRX.

yeh just done it on the way home. 65 around before 8k rpm, not even close to red lining.
pressure is down to 0.8 . time to reset the ecu. if this dont work back to scoobytec before pod ;p

Timed using your speedo I presume?
Remember that this is very likely not correct and will be over reading (by law) rather than spot on.
The legislation regading a cars speedometer are below:
The UK law is based on theEU standard, with some minor changes. A speedo must never show less than the actual speed, and must never show more than 110% of actual speed + 6.25mph. So if your true speed is 40mph, your speedo could legally be reading up to 50.25mph but never less than 40mph. Or to put it another way, if your speedo is reading 50mph, you won’t be doing more than 50mph but it’s possible you might actually only be travelling at 40mph.
Chances are you were not quite doing 60mph when you thought you were.
Best way is to use Satnav speed.

My WRX doesn't hit 60 in 2nd even with a 7500 limit so the STI must be slower lb for lb for the other reasons.

So I also don't believe a 330bhp wrx will keep up with a 450 Sti!!
Did some number crunching on power to weight ratios between the Sti and wrx.
A uk 2005 wrx weighs 1390kg
A uk 2005 Sti weighs 1470kg
If both cars had 265 bhp that would give a bhp per ton of
190.6 bhp for the wrx
180.2 bhp for the Sti.
The wrx would have a 10.4bhp power to weight advantage. Hardly enough to destroy a Sti!
A longer gear ratio on the wrx would mean it would have a slower in gear acceleration than the Sti, but would hit a higher speed in that gear,
Think I'll take the extra weight knowing I've got the stronger gearbox, limited slip diffs and bigger brakes.

Can't remember what engine Steve was running at the time, either a 2.5 or 2.35 with a GT30R, running around 500/500 despite his claims otherwise. Said see ya later to him too.

My mates 2005 wrx with circa 300bhp gets left by my 370bhp 440ftlbs hawk Sti, and every time he's in my car he wishes his pulled like mine!
So I also don't believe a 330bhp wrx will keep up with a 450 Sti!!

P.S your's is considered the perfect road engine and the only thing that puts people off is the various problems associated with the 2.5L and the cost of repair.

One guy wanted to race me in his 500hp Classic WRX to prove the Newage STI was quicker then the Newage WRX!!
...and they say I'm mad!
I'll just get my mate to bring his R1 out to settle things once and for all. I think the STI fanboys have taken 'Born to race' too literally. It had a top mount, 9.9secs can't be done!!!!!! Unless it was Fat-Thomas whupping his wife's 215hp Bugeye WRX in his 430hp Blob STI that has created SN WRX denial?
