Well first of all what ever you do dont cheap out on a battery.....the best on the market are SMC Lipos IMO

Then just buy a cheap rolling evoIII because your TB02 wont stand up to speed runs

The fastest motor esc combo is probally a LRP 3.5 combo

You could always get a Team Tekin 9000kV motor and a Tekin R1 Pro ESC.

9000kV*11.1V=...enough

But yeah, a lot of hop-ups would be needed.

What about a Mamba Max??? It can handle 14.8V.... but use an external BEC or it'll heat up too much.....
Now... motors... I dunno how it will go with a Speed Passion 2.5....

Default in case

If you want a 2.5 for this purpose. I have one for sale at www.fastcats.ca and www.durhamrc.com. This 2.5 was used by me for about 6 packs, was beating the nitro cars for straight speed regularly. IIF I could keep it on the track.

At 80mph speeds I think your going to need a high down force body, and some serious skills. I hope you know it's not "only looking to do around 80 mph" it's HOLY COW I HIT 80MPH! just a few years ago people were having a hard time hitting 100mph on 24.0v+ systems. I understand brushless was just coming around back then, but to hit 80mph is no small feat in a TC.

A few mods I would think we help... lock your diffs, if do move to the Evo III set up I would tape up any holes in the bottom of the chassis, to prevent any air get up in there and lifting your car making loose traction. Also I'm not sure if going as light as possible will work out for the best. At those speeds you need a ton of traction, and the extra weight will help. Most of the time it's crazy gearing and crazy power that will get you to crazy speeds

Take a look at RC Car Actions speed challenge for some of the things that those guys did. I know a couple of people had their cars "fly" of the track they were going so fast. I'm sure someone on here is going to throw in the whole Traxxas Rustler VXL going 70+. RCCA did a review to see if it really would go 70+. They had to gear it to the moon, change parts, and throw in a HUGE 3s lipo and I think it only got up to 68MPH IIRC.

Good luck and let us know how it all works out

Jay

Castle Creations would be a good start for all out speed.

No Matter what ESC or MOTOR, keep the RPM under 65,000 for 540 (36mm) motors. Most rotors will blow after that. Some make take the stress beyond that, but not for very long.

Hopefully if you go with a higher voltage setup (14.8+) less amperage is needed so less burned up ESC's and Motors. High voltage requires BEC moduals to keep the ESC from cooking.

I don't think you want to lock both diffs, have you ever driven a mod TC with a spool in the back? it's near impossible to keep straight when you give any throttle. You'd be better of with a really well built ball diff or a gear diff if you can get one for it.

Accaully NO. I've only run a spool in the front. It seemed to help with my straight line squirt.
