yes i will send them with th rod/wristpin order tommy

not so sure i would want to run the 6mm in the toro with the characteristics and nature of that engine design but

usually jumping down to 6mm from 6.5 there is always a drastic change in tune , dont ask me why cause i really dont have a definitive answer on that one but my best guess is that size venturi is the threshold of proper air/intake and jetting ??

the way the venturis work it doesnt necessarily cutoff the idle gap but it does disrupt airflow quite a bit . remember 6mm needs to be ran very lean , highly doubt you will see low engine temps and a properly running engine with small restrictors

tuning engines is fun


not
see above

absolutely bro , shouldnt be an issue unless you get into the newer lowered team heads

Monty, I have just threw a brand new P5XLT in my buggy. Is the Dynamite 086 is comperable to the nova 9886 / 412021 combo. For Rev. in So Cal. And what is the proper shimming for 30% byrons

I like the 7mm in the standard Toro Nero... It isn't too much or too little, Plus I got 10 minutes of runtime consitsently in the Buggy and with the 9853ss.

On the P5 I use the 7.5, but I might try the 7 just to see what happens.

By the way monty. I had a friends 367 Nova, the blue one, and it was running funny, so I put a 99 OD plug in it, and problems solved. Those 7 ports seem to like colder plugs. Should I try the 99 in my p5 too for the summer. the mc-8 isn't lasting very long in the hot Texas summer....and my engines are running about 220 in the winter and about 250-260 in the summer, is that too hot???? It seems to be fine, I really don't tune for temps, but I thought you may have some insight.....

Monty and all

thanks for the guidance re restrictors on the TN. I'll keep testing for the fun of it I think the airflow is completely changed vs. the 6.5mm, not just about the idle gap and "simple" stuff like this. The air is accelerated more (same top opening, different bottom) and so on so forth. Very interesting fluid dynamics issues.

I can get 9:45 from the TN with the 6.5mm, 9901, 41030, 97T, Mugen carbon shoes, 13/46 and .9mm springs and a light throttle finger... I was trying to hit the magic 10mn mark

testing is fun

Thanks all,

Paul

dyn 086hs is a very good pipe on the p5xlt

Hi Monty,

Sorry for being a pain in the backside. I know you mentioned before the best pipe header combo for the older, 08 production model Novarossi P5TX. I can remember two, but having difficulty remembering the third.

1.Dynamite 086 piper with 41021 header

2.Werks 2013,

3.One other Novarossi pipe and header combo which makes this particular mill ballistic, could you kindly re-post pipe and header combo? Please

Thanks for your help, kindly appreciated.

truggy 2084ss/41021 or 9853ss/41021
buggy 9901ss/41005 or 9886/41021

the 2013 pipe also works pretty well as does thunder tiger or AE 2035 , dynamite 086hs , msr bullit 1005 , dynamite 053mr , ofna 086 w/round header such as 41021 , one of my alltime favs is the 2032 made by rs competitions and jp racing .

there are many that work , im not much of a fan of the jp pipes on novarossi but to each his own

Thanks Monty.

no prob bro

I'm pretty close to start race tuning my P5XLT, caus now I'm only getting 7,30 runtime.
It takes time to for the idle to drop, even if I have the LSN at 5 rounds out.
Is the cure to lean both LSN and Idle stop?
Running it at 180-200 (yes a bit more than slightly rich...)

HI Monty,

I have been using the jp racing 2031 on my toro nero with great sucsess... Yes it is an onroad pipe and i have no idea how simular to the 2032 offroad pipe it is but on my MBX6T with 6.5mm restrictor and a lrp med (i think) curved c shape type header acheive 10 minute run times and power is awesome both down low and up high i find.. Might be worth checking/testing out?



Dave

YES!

hey you can cut 1/4" off the stinger without changing the pipes performance? right? thanks

what runtimes should I expect from my P5XLT(filled crank), currently I get 7,30-8,00 when i run it pretty hard (at 230).
I use 6,5 restrictor, started on the second gallon Mecca 25%.
Running a dynamite 086 with 41029 header, 97T plugs, airtemp 80 and dry.

Just need to figure out how much to lean out this devil...

Hi.

You'll have less pressure in the pipe. Engine will run cooler but I doupt it will do you any good.
