rick oxley

can someone from reds confirm which engine out of the r5r and r5team has the
most bottom end as i have heared diffrent opinions on this.

blis

The answer to a question like this will always be subjective.

The manifold and pipe, plug, clutch, gearing, engine tune and tyres all have a part to play, even the air temperature, so expect different opinions.

R5r

I just bought the R5S for my truggy and was wondering what kind of run time I should hope to achieve?

Depends on your goal and where/how you race. It's the constant risk vs rewards fight depending on how many minutes your main is. Basically, even with a moderately ok tune, 8 minutes is very easy to get in truggy. You should be able to get 10 without significant issues, but it's always a risk on bigger tracks and when pushing the speed/limits in a main.

The real answer is, tune your engine for the right temp/performance, then see what your runtimes are and if they're around what you're looking for.

2112 HIGH TORQUE for medium to long tracks
2113 HIGH POWER AND TOP SPEED for short tracks

this looks the wrong way round to me
is this a mistake?

I think its backwards aswell. The 2113(formally 2069) is a torque pipe. The 2112(formally 2034) is a top end pipe.

I've been running the 2112 on my R7, but have a tight high bite track coming up, and put the 2113 on. We'll see how it works out.

I have a really dumb question on my engine. I just put in my new 5TH and was running it on the track and was running great, temp was around 190. So I went to lean on it and it created a bog. Somtimes it was half way in the straight and somtimes was at the end of it. I could not get the temp over 205. Any ideas?

Your to lean on top end. Reds engines does run alot cooler than moast other enignes due to the design of the head button.

What's average running temp?

RokleM

Agreed, it sounds like you're lean bogging at full throttle.

Are you leaning it out because you're not getting performance or leaning it out because you believe the temp is too low? I run from 190-225 range depending on the track and ambient temperature.

Yes I put more fuel to it and it helped I just was new to reds motor and seen the temp really low. I was worried it being to low I guess. It ran best around the 195 range. Love the power with it. I also was fighting a storm rolling in and kept havin to play with the tune. Thanks for yalls input.
