Default Axial engines??????????????

So I'm kinda stuck on what engine to get for a truck I'm building. Axial .28RR-2 or Axial .32RR-1. Both big block, but the .28 has a 39,000 rmp max and the .32 has a 37,500 rpm max. You would think bigger means more power but I kinda thinking that might not be the case here. I'm kinda new to the nitro world and any help would be much appreciated.

Based on what you are putting the engine in, you probably should post this in the Off Road thread.

You posted it here , so I'll answer it here. The .28rr is more rpm and would work great for racing. If you use the .32rr , it will have tons of torque for the truck and not quite as much on top. If you want to pull wheelstands go with the .32.

+1. If it was my truck I'd go with the .28, much more rpm. The .32 is a complete
crazy torque monster. But it has an ok midrange with no, zero top end. For bashing or racing I think the .28 has what ya need.

What truck will it be going in?

When it comes to the best ,there is only the OS .28XZ modified by ABmods !!!!!! Axial engines don't even come close !!! Checkout the ABmods dyno graphs at www.abmods.com , and you can see the difference.......

Did not want to send him away, just felt he would get better info from the off road section.

I run several Axial engines in my Ofna DM-1, currently have three in my box. All .28's Spec 1 - good engine with torque and some top RPM's - Spec 2 which is similar to the first and a Spec 2 RR black engine that I have not broke in yet.

One area that I have had issues with, has been the carb. Seem to leak around the mid needle and one carb would not tune well at all. Changed the carb and all things became good.

On one of my Axials I've had the midrange fall out. Carb sealed it in and no probs since.

Grenade10 get that RR-2 broken in and drop it in your DM-1. I have one in my
Inferno and it's just a monster of an engine.

Sorry, thought I had posted this in off road. It's going in a Monster GT that I'm building from the ground up, all aluminum parts, custom painted body, Axial 8-spoke 40 series beadlocks. Not sparing any cost. Going to be a show truck and parking lot queen for a while or until I roll it be accident.
I can always change the spur and clutch gear to get more top end though, right?

Well if thats the case. Go ahead and slap that .32RR in there. Drive it before ya regear it though. You may like that insane bottom end.

Honestly, I think I'm going to be looking for a 50-50 set up. Love watching them scream by, but still want it to step off with out hesitation. I put the 3 speed in my Savage X and I love it. Have more top and bottom end. And we have a free to the public out door track about a mile from my house so I'll be down there a lot. So I don't really want it coming off the ground every time I gun it.

Well. Either engine sounds like it should do what you're needing. For just awesomeness put in the .32RR. Then you *almost* always win with the "i have the biggest engine" war. I put a .32RR in a 8.0MGT at the shop i work part time at. That thing had so much power compared to the 8.0. Just match the engines with a good top end pipe and call it a day.
