Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.

Not allowed in my class full spools or locked diffs are alright, they do give a little more push on turn in but they are quite controllable and you can drive the cars fairly well on the rear tyres. Cant be too greedy on the throttle in the wet, as if found out a few times
here a video of what can be done with a locked diff, watch the RX7 driven by Adam Ubergang going round a corner at morgan park in queensland

Having rallied with adjustable diffs I have to say I had a different view when they were screwed right up. Scandinavian flick the only way to get round tight on tarmac Do you guys have fairly open corners ?
The short clip seemed to be more drift than race
Are you not allowed to use "plain" LSDs ? Then adjust them up so they only release grip on slow changes ?

I would also add things like weight and balance. If you have one wheel with consistently less weight on it that could make a difference in both FWD and RWD. Also, if we are talking about a Celica old enough to be RWD it is quite possible that we have some tweak in the chassis or drive line that causes inconsistent application of power to the rear wheels.
Actually, didn't the RWD Celicas use sold axles in back? If that were the case, the torque of the drive prop shaft causes the axle to twist in one direction (reaction to the prop shaft torque). Any of the drag races should be able to tell you about that. That axle twist results in more load to one wheel than the other.
There is definitely something going on, I just wish I knew what it was with certainty. Interestingly I see the same behavior in my van so I don’t think there is anything too abnormal with the Celica.
The third generation had both a SRA and a semi-trailing arm IRS, I have the IRS.Actually, didn't the RWD Celicas use sold axles in back?

"In theory, theory and practice are the same. In practice, they are not."
But with a locked diff if you keep the power on under acceleration then the drive pushes the car in the direction it's pointed and not where the front wheels are pointed More traction on the rear due to weight transfer. Scandi-flick unloads one of the wheels and allows it to slip and so you can control the direction of "thrust"
IN the MG, how do you reverse into garage/across line around a marker ? Definately troublesome

Yeah its a bit of drifting, that is footage of a astate rond and he had a sizeable lead and was showing off, the footage only had about 20% of it.
I can run a LSD and trying to source one at the moment, Ithey are bloody expensive and I need to convince the wife I REALLY need one
Heres some pics(crap phone pics) of the nephews diff, it broke the welded spiders, it has been in the car 13 years.
Have a new centre being done as we speak, the axles were fine which is great as they are specially machined to suit the width of the axle.
