I think there's also another form of TTO - the one where an inexperienced 911 driver enters a turn too fast and realizing that mistake, lifts off the throttle, causing an unexpected TTO situation and likely a spin.

I'd call the more gentle case of inducing controlled oversteer and understeer by lifting the throttle and then applying the throttle by the phrase throttle steering. I think TTO is one of two conditions that you use to throttle steer - TTO leading to oversteer and a tighter turning radius and Power Oversteer leading to understeer and a larger turning radius.

Bob, I know there is no similarity between TTO and Oh Sh*t :wink:

I would suggest that steering with positive throttle is only possible if there is unused potential available in the right peddle. I have had the right pedal flat without the desired rotation, and it is frustrating. Power throttle oversteer is lots of fun. On the other hand, from skiing one learns that any "chatter of the ski", ie slipping or unnecessary movement will result in inefficiency and slower elapsed times. But why let clean lines limit your fun, unless you're racing for points or money!

The gem that I have gleaned from this discussion is Kurt's advice to left foot brake without lifting. You can get the weight transfer and subsequent rotation without the loss of engine rpm and power. Need an opportunity to try this technique. Good discussion.

Unintentional double post? Sorry

Welcome Kevin!

Saw it was your first post. We have a tradition of "inspecting" your motor in this crowd ...often after it is on the ground in someone's garage :lol: What's a good time / date for your engine drop?

Cheers,

Jason

No time is a good time for a 944 turbo engine drop. I think the shop manual estimate is ~20 hrs for removal. It would probably take twice that estimate with no previous experience. So, the weekend remove and replace that you all are used to may have to be scheduled for a holiday weekend? Is there a holiday coming up soon? I know, x@!*&# waterpumper? Not what you had in mind when you suggested a look see. Maybe just open the hood and stare in there for a while. That's doable. Particularly enjoyable while simultaneously employing cylindrical liquid container tools in right hand.

I always associated opposite 'lock' as pretty much turning into the skid, except that opposite lock assumed that you'd hold it for more than just a temporary correction and it often involved hitting the steering stops. The people that are in drift competitions judiciously use opposite lock.

That's not true. Dave R. has REPEATEDLY posted about home much he likes working on FEWC cars .... :lol: In your case ... it'll be an engine Hoist instead :wink:

Huh. I thought the word lock in opposite lock meant steering wheel lock, as in turning the wheel all the way to the stops in the opposite direction.

Now admittedly, there's no way you're gonna get there unless you're in a kart or a race car. So in practice I thought it meant steering opposite the direction of the turn, more in the direction of travel, to catch the spin as the car was rotating in oversteer.

I agree. Perhaps it was shortened from "opposit towards lock" or came from karts / F Ford, etc... where that much turning of the wheel WAS full lock. Generally accepted as you described above. On our cars with big steering ratios (aggravated by bigger steering wheels) it would take a few full turns of the wheel to get to complete opposit lock (COL - new term :wink: )

The term is FULL opposite lock as opposed to opposite lock. I heard this term way back growing up in the U.K. so it must have something to do with whitworth. :? WRC drivers demonstrate opposite lock almost every corner, full opposite lock usually comes before "Oh S**t"
