Anyone have the 392 at a track and if so how did you launch it, what did it run, did you air down or up?

 

[Viking Jeeper]

I'd like to hear also.

I’m seriously thinking of taking mine to Rock Falls Drag Strip. I think a time slip would be Fun. I was going to just drop the hammer and fly. I was hoping for launch control. But manual doesn’t mention it.

I am thinking of going to Famoso Drag Strip outside of Bakersfield in CA as it is the closest. I am very interested in trying the Torque Reserve, which seems to me to be a fancy way of saying two-step. Turn off trac control, leave in D and just go for it.

Hold brake pressure for 2-3 seconds, RPM about 3000…when the sound of the engine changes, let it rip! That’s a torque launch on a 392

 

[Grampy22]

I will have to give that a try. Thanks

Or put another way- how to age your drive train 3 years in 30 seconds. Ha ha

Great. That should help on track day. The Jeep has a pretty aggressive launch with out that. I will be interesting to see the difference.

Thanks for looking that up. I went out and play with it today. Neato feature. It definitely changes tone. Brakes start to break loose at 3000 rpm.

LOL I read this thread title as DISgracing, Thought maybe you got beat by a Bronco or something...

Exactly…more RPMs is not better, mine starts walking also about 2800, when it does start to walk I don’t usually get a change in sound so no reserve. It still throws you in the back seat tho

If it is walking then you do not have enough brake pressure. Pump brakes up three or four time and the hold. Should be able to feel the engine dropping cylinders, once the engine drops cylinders you are max rpm for launch. My 62 Nova with blown small block and adjustable two step allowed me to launch at different rpm based on track conditions.

Yup. That’s it. Exactly.Still good fun. I will have to mess with it some more and try to get my timing down. Hopefully I don’t break anything before that happens. Weather in MN is that great today. Practice will have to wait.

Great advice. Thanks Bub. I could hear a change. But it starts walking shortly after. Cool Beans. I’ll start working on it.

I may have done this last night without knowing what I was doing but I swear the front tires came off the ground for a spit second! The best part of the story is the guy riding along for the first time is waiting on his new Bronco The look on his face was worth buying this beast! Haha

He may be waiting for a long time as Ford is having engine failure on the Bronco

You have to put a decent amount of pressure on the brake to make it happen. If you don't press the brake pretty hard and have steering wheel perfectly straight, it will not go into torque reserve mode (not 100% sure on steering wheel part). When you get it right, you will definitely hear and feel the engine note change. Shifts are very positive (AMAX shifting) in this mode as well. Very notable difference. Less torque management during the shift. Everyone I've had in the passenger seat has busted out laughing when I did this. It is so ridiculous and unexpected.

I want to see a 1/8 or 1/4 mile where someone does the torque reserve launch properly.

...vs just flooring it as a comparison.

I’ve wondered if off-road+ makes a difference in launch performance. It definitely sounds great.
