Motor Speed - What to choose

[DaveG28]

Hi all,

Does anyone run 4.5t in their 4wd, or is everyone pretty much on 5.5 or slower?

I've spent the winter running 5.5, and although its great a lot of the time I can enjoy myself driving sidewards just as much as I do going quickly, so I'm tempted to try even faster!! Don't want to do it though if I'll end up dumping or changing diff's/belts every 5 minutes!!

I'm aware it probably won't make me quicker over 5 mins mind, for that I need to concentrate on how I drive it, the cars fine I think!

i ran a 4.5 novak in 4wd all last year and it never felt over powered like most people would suggest. Even on looser surfaces it was fine with a bit of thumb caution.

But it's probably not worth you moving from a 5.5 to 4.5 as like you say it probably won't make you any quicker round the track, or maybe even a second slower/lap.

.

Seriously?

Was this on old cells by any chance?

A 5.5 will be more than enough, don't bother going any higher, the tops guys normally run 5.5's to win nationals! Cells do make a massive difference though, my 6.5 keeps up with others 5.5 on different cells.

[DaveG28]

Cells make me , I'd swear I follow all the advice, I have really expensive cells and charger, but I still seem to find a way of loking after them badly!

[jim76]

nope, IB's with 1.237v stats. And yes it was geared correctly!

All depends on how you drive though, personally i'm a throttle junkie but i generally run a 13t unless it gets really slippy and i learned to drive with the back end out, so much so i couldn't drive 27t carpet with mini pins on cos they stuck too well And this has pretty much always been the way i drove anything competitively, driving games, race sims, go karts etc

I've ran a 4.5 around polished wood floors, it was insane but I dont think I would actually race it like that as your just causing yourself more work. A 5.5 on good batterys should be more power than your ever likely to really need.

[DaveG28]

Interested in going sintered, which with LRP means either a 4.5 or a new rotor, I've heard 13mm is the right rotor to get (I believe these are legal now?), anyone know if I'll have runtime issues in 4wd with either of these options?

[Chris Doughty]

I have run the LRP 4.5 sintered in my 4WD before, crazy fast. brakes are alittle harsh too.

I can't understand how people are finding 5.5's slow?? I will be 5.5 bonded in my 4WD this year, 6.5 bonded in my 2WD car.

4.5's are for Southport and Oswestery

[GRIFF55]

have a think about the orion motors Dave, sintered and very quick!!
5.5 in one of them would be fine mate

[Southwell]

Ive run my 5.5 Novak and it is insane, i wouldn't even entertain the idea of putting anything faster in for competition use.
