Default Motor question for Dennis

Dennis ,Nice to have met you at the Nat.
My question is how much difference in power is there between the side and rear exhaust motors?
I did a little experiment with the tank and fuel line on the ntc3
Even with the Mugen tank , filling the tanks was good up until the very top of the tank.Then the vibration was so bad you can't even get the tank full which intern is causing everybody to run out of gas before the end of 5 min.
I tried pinching off the pressure line but it didn't seem to make any difference,But then I did the same with the fuel line and the fuel in the tank went nut's( what's your opinion on this?)
Thanks
Tracy Lipscomb

How much horsepower is it on the RB? The Novarossi S5 is claimed at 1.5 hp.

Tracy,

I also made an insulated tank mount (lot's of o-rings/ grommets) and it seems to eliminate the vibration.

Stefan,
It is until you get to the top of the tank.
I have a 1/4 piece of rubber under the post ,a o-ring under the tank mount and a 0-ring on top of the tank mount and it still viberate.(Only when you get to the very top of the tank.
I ordered me one of the new era chassis this week.
It's a little more rigid than the stock one.
I saw something real interesting.
Someone put a fuel filter vertical on the pressure tube and said this cured the problem of fuel running back in to the pipe.

Tracy,

I tested my new tank today and it seems to work. I can open up the full tank at idle speed and the fuel is calm. Only when I apply the throttle, it starts making waves :-p but that's the same with the Mugen.

I went through 3 tank of fuel and had no problems.
One thing I noticed though is that when I had the fuelline to the motor in an upward arch (like the manual says) I still had some air in the fuel line, which made it hard to re-start the hot engine. I rerouted the fuelline so it lays in a flat, horizontal arch and the bubbles are gone now.
We'll see on Sunday how it works on the track

Motorman,

How does the Collari's XS12 compare to either a stock MT12 or say a JP RS12 and then to your RTU MT12?

Cheers

Andrew

It'll blow them all away. On 20% fuel..Provided of course that you get one with good threads in the case, and the tolerance on the big end of the rod isn't out of whack, etc, etc. Same old quality issues ..

Not sure what you all are talking about. I have the stock Tank with the lid mod. I never seem to have a fuel problem. Car runs great. Prob get 7-8 min out of mine. Seems that you all might be looking for something that is not there.

Not sure. But there only seems to the same people with these problems.

Kinda makes you go Humm.
Everyone in my area, has yet to have as many issues as you all
seem to be having. But then again some people just like to tinker. Tinkeritus - another reason that some people seem to have more problems than some.

Breaking is not a car problem. It is the Driver that breaks the car.

Don't hit any thing and you won't break. To many people trying to go faster than they can drive. Slow down. You will be amazed at your lap times.

Post Which One Motorman

I still would like your opinion on wich motor you would recomend: OS 5-port turbo, Colari XS-12 turbo or a RB 5 port turbo.

The two that I am looking at the most are the RB and the Colari, the OS won't be out for a few months. I have seen the 3 port versions of the motors run and they look great. It is just the port placement on the colari 5 port don't look right. I have not toyed with a colari but it looks like the piston won't drop low enough in it's stroke to open the second set of ports. Please correct me if I am wrong I just need some advise before I plunk down some cash.

Default S5 Screws

Does anyone know the size of the screws that hold the heat sink head on the engine casing and also the size for the screws of the back plate. I really dislike the flat head screws and want some allens to replace all 8.
