I know it's slight but I'm looking at accumulative factors. Why are they lighter? Stronger (but lighter) material for strength or to reduce already heavy drivetrain losses?

You know everything about why the WRX is a better, faster, stronger car yet you still asking the obvious questions, Do the maths on the numbers then try and work it out...obviously in private,
Its not all about 400m runs, Chuck some corners in and its a different ball game, but then you cant be that naive to think to think otherwise can you? TBH I'm only scratching the surface on why the STI is significantly slower than a WRX. It was only a matter of months ago I realised just how much of a difference there is and weeks since I realised it was just more than an extra gear change lol. It's definitely accumulative and I'd like to know all the factors in tuned and OE examples. Weight difference All transmission loss contributors Extra gear change Hitting limiter Wheelspin from extra torque/shorter ratios Extra drag Ride height Lift Engine/oil heat management for top end performance i.e. your first run will give an higher terminal time than your last I want to know everything. |

Material composition is superior, alloy as opposed to steel iirc, by virtue of the fact they were handling more power and torque.

I think the right place to start with this Matthew is a physics degree and you will answer all your own questions, turning forces, inertia, energy etc, or start googling ;)

So weight will negate length? A lighter propshaft will transfer more power to the wheels than a shorter one? (Did Norris Designs run a shorter propshaft this with their bogey EVO?)

Such a poor attempt at trolling that, I`m kinda disappointed, So your Modified and extremely Lightened WRX was still slower over a 1/4 mile than a standard remapped sti spec-c with an exhaust swap and a 12 year old clutch ....Thats is a fact apart from no one has ever seen proof of a 12.6 from you have they...but please feel free to correct me if i am wrong??

should add basic engine specs and gearbox to the list of info, puts some context on achievement.
AndyF - 3.0 Flat 6, twin turbo, sequential gearbox SMG - 2.5, GT42, ? gearbox Mikee - 2.1, GT35, manual gearbox etc etc |
It's hard enough just to source the 1/4 time and terminal off most members.

Nothing changes, STI still a waste of fcukin money. |
Mine was on 11 dead before my gearbox gave up, I don't have the timeslip for it but it was on the 22b team at TOTB two years ago so would be timed somewhere. The time would of been lower if not for gearbox issues :)

I managed a 10.9 recently with 518 BHP

IIRC Gav did a 10.? in it Steve, before the box luched itself. Could be wrong though.
I got told nothing Micky, it could of for all I know. |

Add me to the list:
Full weight inc spare wheel 03 blob wrx, 353bhp 346lbft, 13.18 1/4 @ 103mph. This is a proper road car. Attachment 42370 |
Sorted bud, gonna have to go the lightweight route sooner or later with that power!

Cheers, I like to keep it a car! Needs to be comfortable and safe for my wee girl, actually putting an organic clutch in it and doing away with the paddle
Save 40kg with just bucket seats! Lightweight battery 7kg Lightweight flywheel 6kg Lightweight pulleys Carbon fibre propshaft Polycarbonate windows Lightweight alloys Lightweight wheel nuts Lighter aftermarket suspension Lighter calipers Lightweight tyres Spare wheel and jack removal A good 80kg there which is equivalent to 20-30bhp factoring in transmission losses as well. It's a nice little package for a maxed out 350/350 WRX, a 380bhp WRX is the equivalent to a 460bhp STI imo |

Yep. :thumb: |

Some lightweight parts make the car safer and more reliable. You can even lessen transmission losses.

Yeah nuts aren't that heavy but their weight increases x125 when the wheel is spinning! Like that spinning ride at the fairground where the nipper sits on the inside and still crushes you.

Your physics is quite questionable Mathew. Not exactly following you on that one lol

They probably double in weight when the wheel is spinning so a 1KG saving technically becomes a 2kg saving etc.
The mass of the nuts doesn't change. They will exert a centrifugal force when spun but that will in no way change their mass or weight. |

So you're saying my car is 187kg when my wheels are turning? 75g x 20 x 125 |

Am I right in saying if you put low friction oil in a 350lbft Impreza and drove it around the Nurburgring flat out that the torque figure would be around 400lbft when you crossed the finishing line?
