Sorry overlooked it, price is 389 out of stock.,,

Does anyone have any experience with the S21P3XS? I am looking for a fast revving, high torque engine. that will still alow me to use standard glow plugs. if it helps my preferred driving style is to drift/power slide around or through the corners. so i need the torque to get the wheels spinning when already at speed.
thanks mark

I have the my Clocked Bonito on sale right now for $429.00( $40.00 black Friday discount )...... And it is a seriously badass engine that will have a substantial increase over stock.....

Neil check in ur box had a quick question...

any ideas on this one?

This +4 p/s set was being broken in, about a quart through it. I was just puttering around and the engine quit. Couldn't turn it over, much less start it. Opened it up and was greeted by metal chunks from this...

The same thing happened to my +4 Josh. Right at the 1 gallon mark. The place I bought it from is currently speaking with Nova to try and get me a replacement.

really? Hmm, I hadn't seen that failure before. Interesting

Hmmmm I have never seen a cast piston do this inside 7-8 gallons unless engine was being broke in with the WOT ultra rich method or over reving of the engine occured before break in was complete or there was an upper rod bushing failure which is pretty unlikely with the R7 rod or wrist pin breaking in half very very very seldom have I seen this and is usually caused by the aforementioned rod bushing . I have seen and sold more than a thousand novarossi engines I am sure of that .

Btw , that piston looks very very burnt on the underside , thats interesting cause a)either you are using old nitrotane or b) theres much more than a quart through the engine

Curious as to what fuel you were using?

it's shiny, just a combo of the room lighting plus the flash made some areas darker (you can see there are multiple shadows)

Mine was completely broken in, always pre-heated and I never use fuel without Castor oil in it. My internals look brand new except for the broken piston and metal scraps all over it

Looks like this engine should be in a monster truck. Little much for a truggy or buggy is it not?

Really?

That is definitely not "the norm" with the cast pistons

Curious to know what you happened to make them do that for sure , wonder if you guys
Both did something common?

Yes way too much for a Buggy, but simply awesome in a Truggy ! ...Tho the engine does make big power it is not a light switch at all, it only gets nasty if you want it to...It finds traction like no other truggy engine I have run..doesn't matter if the surface is loose or 100% traction this engine carves up the technical sections unlike anything else...With the ultra long stroke the powerband starts at a very low RPM, which gives it amazing trigger feel and control in the low end.....Has almost a 4 stroke feel in how effortless the engine pulls from the bottom end, which IMO makes it wicked in a Truggy....No other .21 I have ever seen has anything like the Bottom end we are seeing from these engines ..... Even on loose surfaces these engines will still find enough traction to yank the front off the ground...The ultra long stroke gives them something special that has to be felt to be appreciated ! They seem to be able to put more power to the ground with less tire spin then a more conventional shorter stroke engine of similar power.....

agree 100%, my PowerHouse Toro Nero team is the same way

hoping someone can explain how theese three engines will preform on the track.

p3xs

p5xlt

21-4

all seem to use the same rod and bearings, so i'm assuming quality of the three is close. i prefer the engine to acclerate quickly, and have enough torque to get the wheels spinning as i prefer to drift/ powerslide through the corners.
thanks in advance mark
