Wise decision to stick with the short for the time being IMO...

Its had an 8-valve esteem engine with a hot cam. Stock carb. running on 195/45 hankook.

Whats a hot cam,rdkarthik??

And i thought it was a fuel injected setup.

I like the short loop. Its exciting, tight and a whole lot of fun.

But technically, there seems to be some excessive loading (bias) on the left front on all cars on the short loop, that cumulates on multiple laps without time for let-off (*if there is such a thing*). Participants might want to add some reinforcement in that area -- tires, dampers, sway bar, lug nuts...

PS: My lug bolts (left front) detorqued itself in 10 laps and one of them broke its head off. I think Ajmat posted a torn left front tire? Wonder if there were any more....

Yup. Managed to shred a 205 left front. So did Shreshta, also a 205 Dunlop.

BikerSG · 20th February 2006, 18:37

our track is specially hard on left fronts. but if u guys learn to not go in too hot, u can save ur tyres.

we've been driving on the track for years and years, but have never seen the kind of damage that ajmat/shreshta/v1p3r had.

slow-in fast out is the mantra here. if u guys go in too hot then u need to correct mid corner. this is extremely hard on ur tyres and gives you the imnpression that you are going really fast, whereas u actually lose time!

and its not just the short loop, but also the full track that is hard on ur left fronts.

Mpower · 20th February 2006, 21:31

How about running the track in reverse, just to stir things up.
I'm sure even you guys are bored of driving the same track again and again. Plus you can give those left-fronts a break and wake up the right-fronts.

I know kart tracks do that all the time. As long as there is enough run off and you have the armco in the right places it should be safe.

Hot cam usually means higher lift and longer duration on the profile. Usually a Piper285 in this case. But I wonder if stock Mikunis can flow enough to feed that air hog.

Rather than the front, you need to add a sway bar to the rear so that it can start taking some of that load.

...but it's sooo much fun!!!

The reverse track thing seems interesting...can it be implemented???

nitrous · 21st February 2006, 01:11

I don't think its allowed to race in the anti-clockwise direction.
I heard its a strict no-no.

BikerSG · 21st February 2006, 10:18

we have run anti-clockwise in the past - but that was when we were young and stupid!

the track has no run-off at a few corners when u run anti-clock. Extremely dangerous!

Theres no doubt that its fantastic though. Especially for me, as I feel more comfortable taking left handers than right handers (when biking). Not to mention the obvious advantage on tyres.

For racing, anti-clockwise is not allowed as the track has been approved/certified by FIA for clockwise direction only.

BikerSG · 21st February 2006, 10:20

New FISSME pricing:

5 Laps - Rs. 500/-
10 Laps - Rs. 800/-

New Esteem pricing will be posted by this weekend after discussion with the various car owners.

A good chance anything connected to the left front can give (*my lug nuts detorqued but tires were fine*). Wasn't suggesting adding a thicker sway bar though, but securing what is already there. Thanks for pointing that out.

It says here that an overly stiff sway bar *or anti-roll bar* can cause an inside wheel to lift completely off the ground on hard cornering... *unless mr.stiff springs are used to counter that upward force* http://www.turnfast.com/tech_handlin...antiroll.shtml

Well, we certainly don't want any more lift. Viper's Baleno would agree

Mpower has already posted the cam bit.. The car was supposed to be an 8-valver with fuel injection and computer controlled ignition.... Its different now, maybe you'll know at the next event
