I honestly don't think anything is faster than a ZX than maybe a modded ZX.

Just remember that having the fastest engine isn't going to win races.

Maybe the .28 GRP?? But, I've only talked to racers who raced them. They really like it. I have yet to see one race. But, I have seen many .28 XZ, and it does haul the mail..

Maybe if you can't beat them, join them. If I was looking for a .28, the XZ would be my first pick too...

I've ran the XZ and the GRP this past summer. IMO, the XZ had more bottom end BUT the best I could get out the XZ fuel mileage-wise from big track was 8ish minutes. The GRP went close to 9....

The XZ was too powerful. Too much power/energy spent on spinning tires. The GRP had more "usable" power for our track.....

Also, the type or types of tracks would also play into the choice. If I had a lot of short straights with massive jumps after them. I'd go with the more torquey XZ. If its not then the GRP...

I will have to say my buddy runs one of my modified V-specs in his truggy he ran it against a few other XZ. The only advantage the XZ had was in the area where you came out of a corner and there was an immediate jump. Other than that, on the straights and longer runs up to jumps, the XZ had nothing on the V-Spec. He wound up easily winning that race....

All the while getting about 9 and half minutes of run time....

I heard a test somewhere that had all the top .28's dynoed and the .28xz was the most powerful followed pretty closely by the Picco .28...So maybe you could try a Picco .28 against the xz guys at your track.

For all who posted, its a OS .28 ZX, not an XZ

Anyway, pop a Speed in your truggy and then race a .28ZX. The ZX was ran at our local track, but had no advantage due to too much wheel spin and the fuel mileage was low, say 8-9 minutes at the most. Speeds could run 10-12 minutes. Add this up over say a 20-30 minute race and your loosing time overall. If the track was large enough or say a muddy/loamy track where traction can increase then maybe the ZX could take the cake, but still, your fuel mileage will drop again if the truck picks up added weight from the dirt/clay build up.

Scott Hughes did a shoot-out a while back with these same engines. He turned faster average times with the Speed.

everyone always talks about using 21s instead.. because of power.. so what i dont get it .. why run a modded 21..instead of a stock 28? id have to think a nice modded 21 would make as much power as a 28...

I think the speed is too much money($500). There are much cheaper motors out there that can compete with it.IMO
