just to see what kind of times you guys are running on the 1/4 mile and what power the cars are putting out just to see the difference with the power to the times

I got 13.4s at Dreamscience @111mph. That was its third run on the rollers though Carl reckon id get a better time if it was on the first run. Car is running 302.2bhp and 342lbft torque. Heres a graph showing the power result from the first run. Got 301bhp on the 2nd run.

EDIT: What the
is AFR Ratio ive forgot lol.

not being funny guys but rolling road times dont really work as there is no wind resistance or any resistance to the wheels it's just as if the car is on air , i was meaning on a real 1/4 mile track
at crail mine ran 13.63 against a 360+ mk2 focus rs and beat it by 2 car lengths and was beating 330 hp st's by a second i should hopfully get under 13s when i get the diff in

I wouldn't take max horsepower figure as much of a guide to 1/4 mile times, so much more depends on driver's skill at getting the car off the line.

Got to agree with Troy on this one, and I know Crail well it is very tricky to get a good launch there due to the weather conditions.

Fitting the diff will make a lot of difference! Beating 330 bhp STs is hardly surprising if they were running a standard diff(and indeed if they were actually 330 bhp of course!) the ST struggles to put down its standard power let alone any extra! As for the RS i think youll find they arent very quick off the line even with the diff fitted as standard! Not sure why though? Maybe the extra weight combined with a tuning bias that favours top end rather than bottom end?

that sounds quick for just having that done

What 60' time and terminal did you get?

And i don't think you will get under 13 but have fun trying.

not sure about 0/60 time , but was reading up on the diff , teated on a 350 hp st and it was 1.4s quicker to 100 , and across the line i was 107mph so i should not be far off getting under 13s if i get it fitted ,
ps. i will have fun trying tho lol

I am not convinced that the LSD will help, in a straight line on a strip you should not get one wheel spinning/slipping differently to the other. You will normally spin/get slip to both wheels at the same time. So the LSD would not work as it should do (transferring the power to the wheel with grip).

All the time is in the start, so best bet is to have good tyres, that will make the biggest difference.

I have seen a standard one do 14.4 , he broke a drive shalf on the second run

I think youll find the standard diff only drives one wheel at a time but doesnt change to the wheel with grip like the ATB does! On the standard diff the driven wheel just spins! On mine its made a hell of a difference in grip away from the line specially if you floor it in 2nd gear! It used to just light up 1 wheel but now it just digs in and goes! The only downside i have found so far is that when it does let go it understeers like a ****** and heads for the outside of the corner double quick!

I'm with ARW on this one.. A LSD is not going to shave over 6/10th's of a second off your time mate, unless your 60ft times (not 0-60mph) are around 3+ secs? But even then that would be down to the driver more than anything..
Your 60ft time will be on your ticket mate and should be around 2.3 secs at a guess. 13.6 is a cracking time, so i'd be chuffed if I were you. What power are you running, about 300bhp? To run 12's in a ST, you are going to be needing 350bhp+ and some sticky tyres IMO
Oh and nice one on taking the RS too...

yeah its ment to be just over 300bhp but i dont have traction control in mine so thats not holding me back at all , where as it will still cut in about 20% in other st's even if it's turned off and hold them back a wee bit

I've not driven a car with a LSD yet, but when i was doing my 1/4s there was a car that had a LSD and he has a good history at launching the car and he was not getting away from the line as good as nearly every one else. It could have just been a bad day for him/his car but this is the only direct comparison i have to call up on between LSD and non-LSD. Would love to have a go with a LSD through the bends and see for my self what all the fuss is about. Hopefully catch up with you soon and you can try to convince me to add a LSD to my shopping list

Not shore about needing over 350bhp (even if that is possible in a
), i was spinning the wheels in 3rd if i was not careful.
I'm with you on the sticky tyres, they will get you the grip and the vital 10th's to drop the time to very low 13's but i could see it taking out a few drive shafts
.

btw - think me saying wheel spin/slip is not the best description, when i got it wrong and added a bit too much throttle the car more bounced then doing a burn out screeching wheel (if that makes sense).

Adam mate, the LSD should defo be on your shopping list but not for 1/4 reasons, its purely about cornering.

Iv had the diff fitted for ages now and TBH i couldn't hand on heart say it gets off the line any better as such, maybe a tiny bit but nothing major over the standard diff.

As Adam has said, tyres is best choice but watch out for hard launching as you WILL butcher a CV joint, they are the weak link in the drive train and they don't take kindly to 1/4 mile strips and sticky tyres/concrete!

Also Adam, i can't believe your going to embarrass me on here by mentioning my 14.5 sec run!
I genuinely had about 4/5 of a tank of fuel plus a boot FULL of stuff (we where over in the Isle of Man so had all mine plus the MRS stuff, i even left my sat nav stuck to the windscreen!
excuses excuses
)

Just for the record RE diffs and launches etc, when my car was running the WR330 package i got 0-60 of 5.15 (without the LSD on std wheels), when i was running CR285 package i still cracked 5.6 secs (with the diff and 19" rims) which was faster then all the new RS's that ran on the same day
