drivetrain is super free. temp is getting warmer here in singapore. I am using novarossi c6tgc which is the plug I have always used. should I look at changing?

what size restricters are you guys running on a p5 in truggy. on a med flowing track? is a 8mm too much. i am using a 2013 pipe.

Usually start with a 7mm in the truck and 6.5 or 7mm in buggy

Needle settings
 

I have a plus 4 btt 9901/021 1.25 gallons on it. My needle settings are about flush on top and about half a turn in on bottom. A local fast guy said those are rich settings. What do you think?

Flush on bottom and like 3 hrs past flush on top is a fast tune for me

thanks houston
i use the old clutch bell
yes i scuff the clutchbell
clean the bearings (BUt the durango dont have splash guard so my friend who was helping me splash all the clutch!!!!)
what i usaully do with new cltch is give it two tanks of smooth throttle...
flywheel is tight re check that...

recheck all the points that you say and give some cltuch maintenance

will try the car tomorrow and see how it goes... I think it was because of the fuel that come over the shoes... the 4 shoes where all black...

thanks houston i will tell you soon how it goes.. hopefully for th better

Can some one let me know what run times are possible with a N21R / dynamite 086 pipe combo.

Also will the 9901 / 41021 combo work well for run time and power on the N21R also?

Both ?'s are in regard to a buggy

Basically i want to know if run times will get near a plus 4 with 9901 / 41021

I use the 9901/41021 on my modified N21R. It is easy to get over 10 minutes in buggy. Expect about a minute less runtime with the 086. The stock engine was close to making 10 minutes with the with the 9901.

Runtimes are close to the +4, but the N21R has smoother bottom end.

Plus-4 Team
 

Well I finally had the chance to race the plus-4 engine. I had been using p5's for so long that I really have not tried the 4 port....

I had a great time. the 4 port had the perfect mix between torque and smoothness and with plenty of rpm's. I can drive it punched and it stays the same temp all race long, I can see now why the top drivers use the 4 ports in buggy. I used a 7mm restrictor, a 9853ss pipe and the short mugen nova header....Fantastic engine....

Having a new engine is like a kid with a new pair of shoes, you just run faster...:lol:

Hi, I just bought a new Losi 2.0 buggy and I'm going to run my toro nero factory tuned motor. I was wondering if anyone has a good base setup for this buggy/motor. Right now I have a 9901 and 41020 exhaust on it. Any info would be appraciated.

Just ordered a new Truggy (Mugen MBX6T) and since I love my Plus 21-4T so much in my buggy I want a Novarossi for the truck. The track I run at is mediumish in size, with sportsmen like me running average laps of 36-38 sec (pros run 32-34 sec). What engine, pipe, and header combo should I be looking at?

Thanks,

Shane

Well
 

I recommend getting a p5 from Houstons Engine Service and add the double sealed Nova bearing, sillicone filling the crank and the HT service. It will give the truck plenty of torque to clear the jumps and will make it easier to drive...

the 9853ss pipe with short round nova header would work perfectly...

need a new P5 / JP B5t turbo combustion chamber, older 28002 type
is # 28011 ok ?? or 28010 ??

I would go with the plus 4btt for the best laptimes, and runtime. The p5 gives too much power when leaned out, and crappy fuel mileage when you richen it to have controllable power. The plus 4btt has plenty of power for truggy, especially my modified version. It will also run for 15 minutes in
most conditions in a truggy. The p5 is great if you want to have the biggest roostertails. :lol:

Are you racing at loganville?

Yup, I'm at Loganville... I'm the guy that sets up the red and black pop-up that has the 7 y/o with me all the time (my crew chief, Brett).
