Anyhow did some adjusment today. I took out the front stab and replace my Kyosho silver spring with a Kyosho Florecent green colour geen spring (I think it is meant for Kyosho GP Alpha series). It is softer than the silver. The on power steering increases significantly but still not up to my Evo's standard. Will try to harden my rear set up next.
I think you can easily see the effect of that by running a new front tire with a old worn out rear. I personally never like how that handles--it seem less predicable and harder to drive smoothly.

I too took out the front anti-sway bar and that helped significantly. I still have a push but it's more managable. thus far I have also tried less droop in front, more caster, more inner shock position, and 35 front tires. They all seem to help but I think the 35 and taking out the anti roll bars helped the most.

The other thing I think helped a lot is the thicker diff oil in the rear. I am running about 20k in the rear as opposed to 10k kit oil. This helps on power steering but also took some off power steering away.

The one for fron one-way is about 1-2mm shorter. It will work but may pop out in a big crash.

Default Need help with top speed/big track

Hey guys, want to know about drive/gear ratios. Tried reading about it but don't really understand (i'm abit impatient) I see the setup sheet, and want my car to have enough top speed. I'm currently running 22/50 and 27/45 with 39T ring gears . If I changed the spurs back to 51 and 56, would my car be faster than it is now on the top speed? Don't care about the low end as much. I'm getting blown by at the straights (large track) I don't want to blow another big amount of cash on the kawahara's 0.8M internal drive system. Please email me if you have any solutions/advice. Thanks all.

Hey Buddy, what kind of engine/pipe have you got? I run too at a large track and I can keep up with everyone. I have not changed my pinions and spurs but did install the 39T steel ring gears. I too thought my car was undergeared until a couple of guys at the track help me tune my engine (NSR5) right. I also think the pipe makes a big difference. Get a Kyosho pipe, they have 3 for this car (5.2, 6.0, 7.0) and these pipes work a lot better then the cheaper aftermarket ones out there.

Also, do you have your 2 speed working right? The stock setting is way too tight. I'd lose at least another 1/2 turn so the 2nd gear will engage sooner.

Hey Jeffrey, thanks for the reply! I am newbie here! I run an RR12 longstroke 5. I am using an aftermarket one piece pipe, i think JPL. Are the kyosho ones that much better? the engine seems to be revving and super strong on out of the corners, but seems like it's not going on overdrive. Any suggestions my friend? Yes I have the 2 speed working great, first i had it shifting too early and when i went down the straight, it took longer as it was redlinning already. But after i tightened it up abit, it shifted later with enough boost prior. Just the straightaway i'm gettin eaten up by Max's

Thanks!
Buddy

if you are getting eating up on the straight, then it is probably because your car is undergeared.
Play around with the gearing and see what happens

You mean changing the spurs back to 51T / 46T...

If you do that, your 2nd gear FDR will be up from 5.0 to 5.11. You loose a little top end on paper.

I think if your track is big, there is no other way about it as the most minimum FDR to get the highest top speed on the FW05R is 5.0. You could increase your top end by using larger tires but that would hurt your car's handling or unless you can get your engine to work over 40,000 rpms !

There's really not much options for the diff style gearing on the 05R. I mean nothing that can get you to insane top speed as once HPI had put it. I know that engine is capable of high power output, it's definitely the gearing. The engine has been tuned by local track experts (mainly 1/8 guys who are not much into TCs)
Oh wells, maybe i may need to get a different pipe. Or just get a Max?

This is a torquey engine and shines more at the bottom end powerband. You need a pipe to compensate for the higher end RPM.

With the FW05R, you generally need to have a high revving engine like the Sirio because of the higher FDR.

Perhaps a different pipe would help... A shorter one would benefit high revs. Don't know which one as I'm not familiar with pipes that are used on the FW05R.

Perhaps getting the Max would help but only marginally faster than the RRL5 RPM wise.

Yes, that's what I meant. The only option i have is to swap to Kawahara's 0.8 ring gears but that set is just too much. Rather save for another engine. But will try out a pipe set first. Oh one thing, the sirios can't catch up to me at all. Both on the turns and straights.

I've never owned a Max engine, so I have no idea how they would compare with my current engine. Thanks for the responses so far everyone. Greatly appreciate!

The long strokes has more low end/torque and less top end/RPM/Horsepower. Just like real cars, torque helps acceleration but you need the HP for top speed. The JPL pipe also does not work as well as the Kyosho pipes. What is Max? Is that an OS12TR? If so, that is one fast engine too.

Remember while trying a different pipe may or may not help, you're straining the engine to run very near the end of the operating envelope. So given the choice, I would change gearing which will definitely solve your problems. Do you know what the Kawahara 0.8 ring gears are and what internal ratio you'll end up with? Perhaps they may and may not help too.

Best is to take a look at a particular fast car at the track and see the make and what spurs / pinions the car is using to get what FDR they are using. Their tire diameters would also help. Only then, reverse that to the FW05R.
