Thinking about selling my Losi 454 and buying the LRP 30X for my eight t 2.0 RTR. Has anyone run this motor and is it worth trading out the 454 for it?

HELL YEAH! MY BUDDY CALLS IT THE STUMP PULLER. IT HAS BRUTE POWER,TONS OF LOW RANGE.

IMO no. The 454 is already too much for a truggy. Though yes, the 30 will have tons of torque, and yes I did see an Asso team driver driving the Nosram version in a qualifier once.., IMO if anything I'd get a 21, or maybe a 25..

If you want to race, I'd say get a 21. Check out a Jammin JPX 21 from www.amainhobbies.com .. If you have money get an OS 25. If you just want to mess around, IMO the 454 is ideal. It has more than enough torque for a truggy, and a better top-end than the 30 will have.

In case you haven't heard before, with truggies and buggies, size/displacement does NOT matter. Most race 21's will make your truggy faster than the 30 will(unless your goal is hill-climbing or something...) Furthermore, the 30 will add a lot of unnecessary, excessive wear and tear on your drivetrain.

There are lots of good, affordable race 21's around these days. Check out the Ofna JLR 21, Jammin JPX 21, Go GXR 5-port, Alpha Z852 or S852, Werks B5, RB Killer 10, etc... All of those are good, solid, affordable race 21's..

Again, for just messing around, IMO the 454 is perfect though. If you got dough and want something really hot, get a modded Ofna or Jammin from Supertib, or an OS 25.

My $.02....

Well I am just going to race my truggy. So a .21 or a .25 will be better than what i have in the LOSI 454 and the LRP 30X?

WALL22

WHat about putting the LRP .28 CARB on the LOSI 454 Would that be just as good as getting a whole new enghine?

I run this engine in my Mugen mbx5t and it has unreal low to mid ranged power, it just rips about. But if your wanting a high displacement engine for these truggies i hear that the Picco is the one to go after.

mrsheldon

THOSE CARBS ARE THE SAME. THE 454 AND THE LRP.28 THREE IDENTICAL EXPECT THE SLEEVE MODDS

supertib

100% agree...the LRP's are fine as MT basher engines, but they lack the RPM and durability needed for extended truggy useage !

WALL22

SO basically the LRP 30x is a no go? Well what about the rumor that the LRP .28 carburator makes the 454 look like a whole different motor?

kirkbride

Depends what your using it for, i only use my mugen for bashing but i bought my Mugen off BudBud and im more than happy with the LRP 30, but he said if i wanted a bit more top end then a picco would probably be the better choice, Here is a video of my mugen with the LRP 30. http://www.youtube.com/watch?v=C-wa7Kx2zx4

Just stick with the 454 and run it into the ground... Then you can upgrade to something else..

mrsheldon

KEEP THE MOTOR., GET IT MODDED (SLEEVE AND CRANK) .THEN IT WILLBE A WHOLE NEW ANIMAL.TRUST ME . 

misasi

If your racing check out the JPX .21. I run this in my truck and it is sick fast. Tons of bottem end

jmaxey51

21 is all you need for a truggy if racing. anything bigger will wear out axils faster and mess up diffs. been there done that.
