Are you sure about the info of going from 1.1 to 1.3 is harder than going from 1.3 to 1.5?
I'm not sure, but I thought it was a function not unlike that of how much hp vs. drag it takes to go faster. I know that is essentially an exponential function and figured the amount of grip, i.e. friction, it takes to keep a car on the road vs. load would be something similiar.

Now that is an overstatement for sure....

Get 3 giant stickers and put them across 2 body panels.. that should be close to getting you there.

Seriously.. To pull such a high number I doubt the car would even be streetable and the tires necessary would not be something easily afforded for a daily driver... (wear quickly)

the tires required to achieve 1.5 g's would definately not last on the street but it is far from impossible to achieve 1.5g's with an FC. Tires are more capable these days than you think.

also, keep in mind that the 1.3 g's was on the track, not a skidpad. I would expect to see even more on a skidpad.

1.5 g is attainable, certainly, but not cheap and not likely to be a practical street machine.

23racer posted a datalog from a few weeks ago at Mosport where he was hitting 1.4Gs. I I don't know every detail of how he acheived this so I'd suggest you look into FC race cars (eg. race forum), as it is rare for anyone in the FC forum to have this type of vehicle and you'll end up getting poor response.

Easiest way? Side thrusters. Car weighs, what? 3000 lbs? So 6000 lbs of side thruster force should get you around 2 Gs. :D

because it is an academic number, it was a number pulled out of my ass. I was thinking about the DTSS and started thinking about skidpads, then started wondering about getting to 1g ease, to I decided to make it 1.5 and if someone could come up with that number how about 2 then? That answer your question?
I never said anything about it being streetable.

I wasnt thinking of it being streetable, mabey this should have been in the race car tech...

I dont even need to look at the link, I just saw your post in the lounge, hehe.

DUH, it's so easy. Cross the freeway when it's busy with Semis and don't look either way, i hear there is a 76% chance you might hit about 2.5 g's for at least a second!

How could you guys have forgotten that?!

sooo soo simple....

Assuming you've already resolved yourself to the fact that the car will be totally unstreetable, here are a couple rules of thumb:
Lower weight
lower CG
wider track (not JUST wider tires)
stickier tires (Hoosier R25A compound road racing slicks)
Good luck

How about two steel cables, one attached to the front and one to the back, and a really strong pole to attach them to! Just kidding.

BDoty311 09-07-04 08:35 AM

You are going to need some very extensive aerodynamic work to get up there aswell.

And then hire Ground Control/Huffaker/ SpeedSource, ETC to help you dial it in. This is the car that Dave (RXHeaven) was talking about. I have no idea what it will be capable of, but it should at least equal a good EP car. Given the much larger tires, it MAY be possible to improve on EP grip, we shall see. Carl

slidingsky 10-16-04 12:12 AM

more important than the coilover or tires. SWAY BARS self explanatory. Cheap too.
Well of course you need the whole package, but thats the most important.
I was running my 20b with no front bar. Konis, 500lb" springs and the car still rolled like crazy. THe bar makes the most noticable diffrence.

With those tires Carl.. if the weight is down, and as you said.. dialed in properly.. you should be flirting in GT levels of lateral grip.

A Team that runs a F500 car I was helping our with recently does 2.5 in the corners via the telemetry data. All the time. Spikes higher.
I am certain with a properly setup car.. and enough meat.. you can certainly break 1.5

Shoot now that I re-read this.. watch any of the TOP Gear vids of the Skyline... they do 1+ just yanking on the steering wheel... and those are BOATS... with DOT street tires.
