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

P5XLT is the one you want based on what your describing...... especially so if it is Clocked ! ;)

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.....

If the engine are broken in, it sounds like too rich bottom and perhaps an out of tune top. Warm up the engine and set the HSN a little rich.

Try the Bernard Durand way here:

Thanks for the replys guys!I appreciate it but my problem is 3 stage idle not 2 stage idle.Ive broken in 5 engines so far and never had this problem.2 stage idle is normal when the lsn is a little rich.The idle came straight down after high rev like it should be when lsn is set right but then it rise up for 6-7sec before it came down to normal idle again.No flame out what so ever and running temp is good.i know this is a great engine because i ran nova p5xlt this year and it served me very well.Anyway i might try diff glow plug and play with the shim a little more and see what happen...

This is my setup same as my p5xlt
Glow plug odonell 97t
Fuel Sidewinder 25%
Pipe Losi re12
Shim .70
