Default Check on my engine tuning

Just want to make sure I'm going about things in the right way:

Start off by richening everything 4 turns on the LSN 6 on the HSN (InitialD's recomendation) and start the engine. I'll then adjust the idle speed to get the engine to keep idling. If the engine dies after I remove the glow plug starter, then I'll lean out the idle until the engine idles without the glow plug starter.
Then I use the pinch method (FAQ) until the engine speed just raises and then dies, then I richen the LSN back one step.

Next I apply some throttle to see if the engine runs clean up the rev range - if not then I lean out the HSN. After leaning the HSN, I check the LSN with the pinch method again to see if it needs adjusting.

Once the engine runs ok with a bit of throttle, I put the car onto the track. On pulling away, I give a bit of throttle - if the engine dies now, I lean out the HSN a little more (1/12th turns) and re-check the LSN. I do this until I can apply the throttle without the engine dieing.
Then I'll do a 3 lap fast run check the temp - if it is below 95 degrees (approx 200F), then I lean the HSN out a bit more and re-check the LSN.
Once I get the engine to around 100-105C then I'm reasonably happy. Go for a longer run and check the temp is still stable.

If during my hot laps the engine revs remain high when I release the throttle (and then they drop down after a few seconds), I'll lean the LSN a little more until the engine revs drop down immediately after releaseing the throttle.

At the end of the longer run, I'll check that the temp is still in the 100-105C range, if not, then I'll richen the HSN a little.

This should be a safe method?

Cheers, Mark.

our new serpent clutch shoes are in. Testing shows a significant gain in punch and performance.

The car is already fast. Faster means more trouble !

Hey Dennis, thanks for the pic. Cool to know that it'll improve performance. Are these available only through you or through RDLogic?

only from me at the moment. The clutch allows you to use the mugen spring that comes on the MTX3 or the serpent 1/8th scale stock spring with weighted flyweights. It also allows you to set the engagement point higher with no slip when it comes in. The car has wicked off the corner snap and unreal second gear punch. (scary)

This is true! Look, I've already melted my engine, as I was going so fast

Just rebuilt the 705 - going to see how it runs at the track today. Should be interesting coming straight from the 710.

D, are you still swaping between the two.

I'm using on of Rene's MACH setups, as they work well on my circuit, too!

Cheers, Mark.

by the way I do like the new car but those alumunium pivots on the front got to go. Yea don't hit nuthin I can deal with that but geez when they snap off the arm is uselless as you cant get the broken part out. I think I'm putting 705 balls on the front end.

do you mean the steel ones from the 705? I've not hit anything yet with my 710 (just those Mugen guys hitting me ), but I know from the 705, that the Alu pivots are really soft and bend easily

I've hit a lot of stuff but I have not broken any pivot balls. Neither has any of the guys where we race locally. Perhaps it's the weather. Colder = brittle.

Anyway, it would be good if you could cut the 705 / Impulse / 950 pivot balls shorter like the aluminum ones on the 710. I can't remember their measurement off my head but it makes the front trackwidth setting easier. If not, you need to thread in pretty deep with the longer steel ones. Don't know if that is possible on the 710.

Since last year I have only run my 705 once and I had forgotten to tighten up a grub screw in the front pulley, so I was only driving with rear-wheel drive man, I thought the 705 wasn't that bad

Now it'll be interesting to see how it runs as my driving is much, much better than last year
