Two of my mates have 21s in thier truggies, one with a ninja in his 8t and another with a Go-Tech 5port (with turbo head) in his XUT and I now cannot see the point in running a 28... if nothing else they use less fuel...less pit stops...


If your heat is 7 mins who cares if your truck can run 10... and if your main is 15 mins.. well you still have to pit

Its kinda like nascar gotta have the setup for the location..

anyone willing to give me an honestm unbiased opinion...(if possible)... i have an 8ight t... just starting getting into racing... always down for a good bash... and im pretty sure i wanna drop in a ninja.... now the big question. do i go with the .21 or .28??? or does anyone have any experience runnign engines int he 8ight t?? thanks

i'd say go with the 21 ninja ! its more usable power and its alot more gentle on the drivetrain! the bigger motors seem to wear out dogbones fairly fast, as you will notioce the dogbone pins flatening outfaster than a 21 would


Thanks a lot. how does the .21 compare power wise to the .28?? the simple stuff..juss a lil less torque than the .28?? how bout top end (as if they were side: who wud win)???

if you want power go with a .28

Thanks.. And the Jammin is %100 identical to the Picco Evo2, right?

(Looks like Horizon doesn't deliver to Europe..)

Also, anybody got the current Amain codes?

I ran a LRP Z.28R/Axial .28 for a season and did just fine. Both engines ran well and had decent fuel mileage. I am switching over to a .21 to get a little less wheel spin. A much better driver could easily compensate for wheel spin with better throttle control and set up, but I am not the best driver. My engines ran against expensive high end Italian mills and fared pretty well. I NEVER EVER lost a race because I was running a .28. I lost my races because I was beaten by guys who were better DRIVERS. Some of them ran .28's and some ran .21's. A .21 will suit me better because I will be able to control the vehicle a little better with the loss in torque. I am a decent Club Level Racer, nothing more or nothing less. I do not need expensive modded engines or detailed dyno graphs at MY LEVEL. My advise is intended for the local racer or basher.

Over here we have 20 min finals and for national level racing max size is at the present time .21 OR up to .28 if its the RTR engine...engine size rules may change this year...

Jaywax I can't help but to feel your comment is aimed towards me, and I can definitely sense a little animosity coming from your direction. Wether its deserved or not it doesn't bother me too much as I know I am right in what I recommend to people.... I may be blunt, and i may tell people stuff they sometimes might not want to hear but I do have my facts straight and my advice will put people into the winners circle


Jaywax I can fully respect and also fully understand that you have been successful with a Axial 28 and a LRP 28....Hell I never insinuated or believed any differently, the driver and setup is what wins the race, the motor is just a part of the overall package. Really when you consider how many factors will affect a machines overall track performance a motor actually plays a pretty small role... Motors are cool and macho so alot of attention gets paid to motors, but in truth chassis setup and tire selection are 100X more critical to track performance...Search any forums and you'll see the motor section gets the most attention, as people can't help to want to know which is faster, which revs higher, which has more torque etc etc, almost pitting motors against each other like two prize fighters in a boxing ring............. But in truth when it comes to track racing the motor is only a small part of the overall package, pretty much any motor on the market is capable of winning at almost any level of competition...

.But even though a motor is only a small part of the package alot of people still have a fascination with having the baddest fastest motor possible, and alot of people really want to know which motors have the most power... So you can't put dislike onto me for offering people advice on engine output, I am only providing people with what they are asking for........People tend to take it personal when their engine of choice makes less power then some competing engine, then in turn point that anger towards me, as if its my fault their favorite brand isn't making the output they thought it did........... I mean its not my fault, if your looking to blame anyone blame the manufacturers who made the motor..... It seems people are all positive for dyno comparisons until a motor they like shows low numbers, then all of a sudden dyno readouts are bogus etc. etc. ..... As soon as people see their favorite motor dyno low they suddenly start to discredit the dyno results stating how motor such and such was plenty fast at the track, and how dyno numbers dont matter at the track etc. etc......... Then all of a sudden the guy posting the dyno graphs is the bad guy and biased for saying their motor of choice doesn't make as much power as some competing engine.....Its a pretty viscous circle really , as people genuinely want to know which engines make more power then other engines, but for every motor that shows high numbers, 5 others show low numbers in comparison...So every time one motor stands out in the pack, we get a bunch of people getting mad and taking the results personally........

The dyno is just a tool, it reads HP and torque, it doesn't recognize engine brand or engine price tags, it doesn't care if a motor is popular or not.. The dyno is a measuring tool, just like a ruler or voltmeter... 14" is longer then 12".... 12 volts is higher then 8 volts, 2 hp is higher then 1 HP. The dyno is just a measuring tool, it measures the motors ability to accelerate a known mass , from accelerating that mass its able to calculate the torque vs RPM and from there HP over RPM ...... The X-dyno is becoming the standard to which engines are judged, manufacturers are now starting to design their engines, there is a very large disparity of engine outputs from manufacturer to manufacturer..

Anyways for those people looking to compare engines, as engines alone the dyno is the only method... A dyno will allow you to compare each engines powerband and power output... Which will allow you to find a motor suitable to your needs, whether your looking for a smooth bottom end of a WS7 or the brutal kick of a Nova 528...Or the top end of OS V-Spec... or the overall powerband of a Ninja 28...... People need to stop getting mad at me for offering my advice, and also need to stop reading too deeply into my advice.. I am an engine specialist, I modify engines to make big HP... I offer fair and honest advice on engines based off power output, i don't make any promises of winning races or improving your driving, I know your Axials, Mach's and LRP's work quite fine on the track.... Hell so do Force engines and STS engines, as well as pretty much any other brand of engine that runs......

But just because they work fine on the race track doesn't mean they make as much power as a motor like a Picco.... for those people looking for the most power for the dollar no other motor even comes close to the Picco line of engines..... from bottom end to top end these Picco's are class leading engines. Don't get mad at me that Picco has done their homework, the dyno charts prove Picco engines have a broader fuller powerband then most of the competition... So don't get mad at me for recommending Picco's over other engine brands... I mean these Picco's make class leading power and torque, they are Italian made, they are backed by OFNA, and they cost pretty much the same as Taiwanese engines .... I am in no way being biased here as Picco has genuinely earned my recommendations...People just assume I biased for no other reason then to discredit their favorite engine line , but the truth is Picco engines stand out in the crowd right now, they have honestly and genuinely earned my praise... They have proven themselves to me in both track and dyno testing, as well as their value cannot be touched.....

Supertib,

It's not that serious. Just because I used the word dyno graph does not mean I was directing my comments towards you. It was used as an example of things that are not necessary for me. I have no beef with you or any other person. I will never get into a beef or argument over some toys. These vehicles we run are just high priced toys. I'm sorry if you feel that way, but your energy should be directed toward something else. It's all good.

P.S.
I have no freaking idea how to read the dyno's anyway. Am I the only one?
