Hey DJ what brand 150,000 wt oil brand did you use? Or has Serpent begin making the thicker oils. Thanks

Julius

With the light diff oil you can expect some diffing when transitioning under power (inside wheel spinning), but according to Michael the advantage of increased cornerspeed is much greater.

Michael also mentioned during initial testing the diffs leaked, and so the diffs got lighter and lighter in those first runs of the prototype. Even so he said the car only mildly reacted to the loss of oil. The diffing gor worse o course but the overall handling didn't change too much. Seems the 733 is not too picky on diff oil, and it might be more of a personal feeling preference.

I for one really like the lighter oils (especially in front) as I do not like the feeling of no turn in under braking with heavy oils or solid front axles!

How is the traction were you race? Is the track sprayed for traction?

European tracks aren't sprayed like ours here in the states what u see on their tracks is the rubber the cars are laying down.

Julius

Normally our tracks aren't sprayed (sometimes early in the season) however as most are permanent and get good use traction is usually good.

The last race for Michael was the German Nationals where grip was high enough to get grip roll on any car if not properly setup. But he said he liked the softer diff oils (and notably very little difference between front and rear) to work in most conditions.

I'll be running my car in Heemstede on the weekend and I'll try to test what I can...

You can now get Xceed oils up to 200,000. They do not have 150,000, but they do have 100,000 and 200,000 and under. I think they go for diff oils from 5,000 to 10,000 and to 60,000 in 10,000 jumps. Then from 60,000 to 80,000 and then 100,000 and 200,000.

They now also have the shock oils from 300 to 1,200 in 100 jumps and then 1,500 and 2,000.

I could be missing some, but I think I am close. Oh, they also have 3,000 and 7,000.


Hope this helps,

Need help with a basic setup for a short technical low grip circuit, grip roll has never been an issue, I have attached a Google earth picture to give an idea of the size and layouts of the track
Any feed back would be appreciated.

I would try the stock setup with full short wheelbase front and rear. It should get you in the ball park. For more rotation thru the corners raise the rear lower hinge pins.

i have a brand new 733 to sell, low on cash the kit is assembled and has the new revised fuel tank included. send me a pm if interested...j

do you know why mickael salven use 50000 diff oil front and 80000 rear ? look last setup on w w w.serpent.com/product/804000/setups/

The setup posted by Michael was 40,000 F and 50,000 R, I am not seeing anyother setup posted except the one labeled 733 set-up Salven - Turkheim.
On this setup as Julius has already mentioned the reason for going to lighter oils. This car has a VERY WIDE sweet spot, that being said I have seeing user here in the US go as much as 500,000 front 100,000 rear or even 200,000 front 80,000 rear.

Here's the general principle of a Diff as how I UNDERSTAND IT (anyone feel free to correct me)

The wheel that has the most traction gets the most power. Typically on the front while cornering this would be the inside wheel. The heavier the oil the slower the wheel spin.

This also works from front to rear, same principle applies. If the rear is lighter than the front, the rear would likely get more power loaded to that axle. The harder the oil the Harder the acceleration. The lower the traction, the lighter the oil needed.

that was Gergely's end setup with those oils. he started with 80k front and 30k rear. then switched for the final to the 50k front and 80k rear.
