We tested the Plus28 and its far better than 528. The pipe we use is Nova 9853(shim clearance 0.9mm)

I have just purchased an Xray XT8 truggy and have slapped a Sirio CL7B STI .21 engine in it what a land rocket it has more than enough torque to push the big truggies along if you dnt want a 28 try one of these baby's out you wont be disappointed.

A few guys at my local track just got those OS .28 XZ's and they and I think they are too much on the low end. I un against them and with them they are not doing any better against me since the got them. The GO .25 is an excellent choice with tons of power low and high and the + of .21 runtimes. Or I would say get a healthy .21, there are a few to choose from.

Default re good truggy motors

if money is no object the rb concept c6 7tt is a really good choice. this motor has an amazing powerband , idles like a champ and gets amazing fuel mileage.


some other good choices are the picco evo2 .21. another great motor with great power throughout the powerband and also gets amazing fuel mileage. its alot cheaper priced than the rb concepts also.

if your racing on a tight budget try out the go tech .21 5 port engine. best bang for the buck in my opinion. this go tech can keep up with the higher dollar motors on the track at a fraction of the price. plus you can get the motor and pipe for way less than 3 bills. a piston and sleeve replacement is less than a 100 bucks. try buying a piston and sleeve for an rb concept or any italian race motor and you will appreciate the low cost of the go tech.

alot of guys go with the bigger displacement engine like a .28 or even a .30 in a truggy but you end up sacrificing fuel mileage. i have never used a bigger engine than a .21 in my truggy and probably never will.

I agree 100% on the go .25 bang-buck ratio. I know people have said these engines had trouble in the past, but honestly had nothing but success with these engines.

That said, my LHS has an open box Orion CRF .21 Off Road 2008 Engine - anybody tried this? Found one review and it said it had ample power and great mileage. Any first hand reviews???

all the engines listed so far are good..it just depends on what you are looking for. Most cannot control the 28's to be faster on a track, let alone the added maintenance from the torque and power. Vspec, Speed, C6, 21-5k, Ninja, GRP, Sirio....all good and all winners....I have had all of the above except for the Sirio and Speed (have driven the Speed though), and by far my favorite is the GRP 21..great power, smooth, never ending top end, 10 minute runtimes, will last a long time, and low temps...tunes easier then my nova as well (not quite as easy as the vspecs though). Vspecs are great for the money, but I the quality is just not there compared to the others imo
