The Jazz 55 is quite capable and with 8s lipo (or 10s A123) it is able to push Truggys (see video in my signature) and monster trucks with ease. The Jazz 55 is speced at 65A burst for 15 seconds. It handles by far more when it comes to short impulses. I have quite a few eagletree records with amp spikes around 100A which translates to 2.5KW (on 10s1p A123).
Having 8s and 50A is comparable to 4s and 100A -> around 1400 Watt in both cases (when calculated with 3,5V per cell). With upping the voltage you won't need ESCs with super high Amperage capabilities.
On 4s the jazz 55 won't have the needed Amps for your Neu 1515/1Y (2200kv). On 8s lipo with a Neu 1515/2Y (1100kv) there wouldn't be a problem (this is the setup i will be running in the coming days as my Neu 1515/2Y arrived today).

No wonder your tires balloon like crazy. I already thought it must be speed demon with an ourunner spinning at 15000rpm without pinion/spur reduction.
@Mabu
Sure thing. It already would have been fun with my Neu 1512 setup.
Like othello and skellyo already said, i am using 8s Lipo and the Jazz can take up to 65A peak, i think nearly 2000w should be enough for a 9.7lbs Revo. If you want to use a Jazz on 4s Lipo, you could try a Jazz 80, it can take up to 6s Lipo and 100A.
I've always wondered how the Kontronik ESC's would handle an outrunner in a setup like this. You sound very pleased with it.
Tires that don't Balloon like that? Hmmmmmm...........the HPI Phaltline tires are a GREAT high speed tire, but they don't grip real well off road. They do stick on-road like glue though. The smoothest tire I've ever drove on. I did a few 65mph passes with them. The best I've found for high speed runs so far.
I've heard the Badlands are a pretty good all around tire.
