one monty is like 2 skinny people:lol::lol::lol:

don't feel bad, big guy. one bignasty is like 3!:nod:

Alright lets not blow up Monty's thread, like we do to everyone else's:lol:

Monty, I know you're the go to guy when it comes to making Frankenstein Novarossi's. Will a Plus 21-5K p/s work with the Plus 4 crankcase and crankshaft? I'm about to build a S821B sleeve with a Plus 21-5K crankcase and crankshaft engine so I will have a spare sleeve.

no , the old sleeves wont fit in the p4 crankcase . but the 821 p/s set will be badass in that 21-5k block , make sure crank isn't out more than .05mm . 4.95mm



plus 821k (turbo?) :nod:

make sure the bearing is good also

So what sleeve would fit the P4 case?

I'll play. You said JP pipes are not that great for nova engines.. I am running a JP-3, unsure which header, looks like a regular round one (just because its what came with it) on a JP 21 B5N motor, it is on a Losi truggy, what do you recommend, and why? what is difference between long/short/square/round headers? exhaust velocity?

Also you suggested 1mm idle opening, is that not too much? I see most manuals list .5mm or so. I do have some idle issues, should I increase it to 1mm?

Thanks :nod:

sorry to say but p4 is 19.2mm and most older stuff was 19.5mm :cry:
the 4 port design is awesome though :nod:

Hey Monty! Great thread man!!

play ???

you can theory all you want , i have done lots of real world testing to come to the conclusions i have spawn .

i believe the square headers work better with torque pipes because they create a better and slower released exhaust gas slowing down the scavaging effect . thats why good runtimes :nod:maybe or maybe not

i dont know about a .5mm idle gap seems pretty low to me , no safety factor built in ;) to each their own though , different engines act different also :nod:

that engine loves the ofna 086 w/ medium round header like your jp header :nod: the dynamite 086hs pipeset also works awesome on that engine . ofna 053 pipeset is another good one


if you want to use novarossi ppipes , the 9886 with 41021 or 41020 depending on how you would like to balance from the bottom to the top . longer header more balance towards the bottom :cool:

monty

play????

easy there, its a figure of speech.. you start a thread saying post your questions.. I said I'll play.. nobody is posting any theories, just asking questions :weird:

Thanks for answering my questions though :nod:

p.s. are you old and grumpy? :D

actually i am 33 and not grumpy at all :cool: i am cool though

i wasn't necessarily saying that "you" were theorizing on the subject to me or anything of the such bro . simply saying there are many opinions and we all know what those are like ;)


hope info helped out bro
monty

He's actually a good guy to talk to. Knows his stuff with the Nova motors for sure. I just bought a P5XS from him and some other stuff and he already shipped it out within a few hours. Can't ask for better service than that.:D

Monte,

How are you doing? I left you a message earlier today. Had a few questions on a motor. Give me a call tomorrow if you can.

Thanks,
