Track set up

Track Boy · Post by **Track Boy** » Wed Oct 26, 2011 7:42 pm

Hi all

My Atom 3 300 was at factory camber settings of 0 fronts and 1.5 rears, I have adjusted the fronts to 1.5 and left the rears as they are. I intend to use it with Pirelli slicks. Is this enough angle, I have seen a couple of guys running with 3 front and rear?
I want the car to handle high speed corners well, the car is only for track use.

Should I ajust the ride height down, if so by how much?

Will I need a baffled sump?

Thanks

I can't help you with the camber settings ( I suggest pm to John Hamilton) but definitely need a baffled sump if running slicks, oil starvation could be a serious issue if you don't.

Cheers,

Stu

as could be upgraded uprights/bearings if not fitted already?

Thanks for the advice Wasp

Stew, what would the sump and the uprights cost? I believe the factory charge in the region of £990 plus £300 fitting for the uprights?

Absolutely agree, you'd be lucky to last a day with bearings running hard on standard uprights.

Even then I believe John H wore some out with the new uprights. That said his were prototypes and he is a nutter.

The new uprights are a vast improvement though and will allow a higher degree of camber.

Cheers,

Stu

Thanks, what angle camber could be run with the new uprated uprights fitted?

Not sure why anyone would need the baffled pan. The SRAs have been running hard for 10 races without them and have zero failures mechanically.

As far as the Alignment settings, I have them at the shop

That brings up the age-old question ..

The Baffled Sump is an optional extra, but most assume the engines are delivered with them already fitted and the engine sealed.

The question? If an order didn't specify the baffled sump option, wouild it actually be removed from the engine?

Unless, of course, you get a better one fitted ...

Through experience, I wouldn't track a car hard without the baffled sump.

Im just stating my experience as well, with this car.

That seems like a good point from John, when you consider a baffled sump is just a normal sump with a couple of thin metal plates cast/welded in it would make sense to have them in all rather than by exception.
On the flip side to this, the engine in the 300 3 would be built for a Honda road car and so a baffled sump would not be a normal part of the built, Atom may need to remove the sump and fit themselves as required?

I dont fancy taking it off to check as I would need to get a set of seals and gaskets etc.

Well for one, I'm completely baffled reading all this!!!!

Cheers Wattie

Like what you did there Wattie!

Just come back from another great track session at Bedford, my god I cant wait for the new wheels with slicks to arrive (two weeks), it just has too much grunt to put down one you have hit the apex for the Yoko 48s to take, and thats on any corner including the long sweeping bends in 4th and 5th gear.

I really want to put some more camber on the rear when the Pirelli slicks go on, 1,5 is not enough although the slicks alone may fix it.

My fastest lap of the west circuit was a 1m23.5 but the swines took it off me for clipping a cone, so the only other times lap to count for the leader board was a 1m25 (gutted). Would have gone onto the 'how fast' leaderboard in 8th if it wasnt for that.

Oh, try it again in a couple of weeks when the new rubber arrives, cant beat £99 sessions at Bedford at the moment, great fun.

You have mentioned Pirelli slicks What size are these and are they readily available?

I have been running Avon Slicks on the 15/16 Dymags for the last 2 years and whilst not unhappy I am always keen to try different options.

I did look at the Dunlops but unfortunately because all newer radicals run a 265 rear the 235/605 rears appear to be hard to come by.

I would be interested to hear your feedback but I'm sure you will love slicks on the Atom
