loftygoals Posted August 28, 2007 Share Posted August 28, 2007 What kind of lateral G's can we expect to achieve in a 944 Spec car? This was my first weekend running data acquisition and I was surprised to see numbers in the 1.2-1.3G range on a car with stock suspension and the spec tire. Is my data faulty or can these car really handle those kinds of forces? -bj Quote Link to comment Share on other sites More sharing options...
JSilverman Posted August 28, 2007 Share Posted August 28, 2007 Is that peak or sustained Gs? If those are sustained Gs Id be impressed considering a stock suspension. Quote Link to comment Share on other sites More sharing options...
loftygoals Posted August 28, 2007 Author Share Posted August 28, 2007 Is that peak or sustained Gs? If those are sustained Gs Id be impressed considering a stock suspension. Peak. But I am sustaining over 1G through mid corner around hairpins. -bj Quote Link to comment Share on other sites More sharing options...
924sowner Posted August 29, 2007 Share Posted August 29, 2007 well my stock, crap bicycle street tire, no sway bar, very old stock sprung 24s pulled 1.18 peak... and i think about 1.1 average. so on a good race tire and tuned suspension i dont think ide doubt that.

That's pretty much what I have accept I have -2.1 degrees of camber in front, -2 rear, and RA1s. I have all stock suspension with the small front bar and no rear. Good number, but lots of factors to consider - like how the corner(s) were cambered, etc. There is 0 camber to the corner (well I can't say that for sure, but I've walked that corner dozens of times and I've never noticed any positive camber to the turn). It is the hairpin (turn 7) at Gateway International Raceway. It is the corner before the infield joins the oval, so it is extremely flat. I saw over 1.2 G in another turn that is ever so slightly off camber. Now I know my G force readings for the banked oval will be way off. Banking does a lot to help keep you on the track. I still think that my software may be a little adventagous. -bj Quote Link to comment Share on other sites More sharing options...
kevintee Posted August 29, 2007 Share Posted August 29, 2007 From another thread: This is a response to BJ Meyer's question about what is normal for 944 g's in a turn. The following is sustained numbers. Phoenix International: This was done with Toyo RA1's-400lb springs-30mm torsion bars-welt's sway bars front and rear weighing close to 2625 pounds. In the oval 1.38g's on the flat surface 1.22g's. This was also in the winter time which the track is much faster when cold. Quote Link to comment Share on other sites More sharing options...
schwank Posted August 29, 2007 Share Posted August 29, 2007 That's pretty much in line with what I see... my Traqmate shows me hitting 1.2-1.3 under heavy cornering loads here at Portland. This is on stock suspension and RA1's. Quote Link to comment Share on other sites More sharing options...

This is on stock suspension and RA1's. Sweet. I'm just amazed by these little cars! Here's what 1+G's looks like on stock suspension: http://www.photomotiononline.com/displayshoot.php?keywords=Car-Clownshoe_944&eventID=14&keyType=car There are 4 pages of pics from this past weekend, enjoy.

kevintee Posted August 30, 2007 Share Posted August 30, 2007 How do these measurements stack up against a skidpad measurement of G-force? I just wonder because magazines always cite skidpad numbers and it would be neat to know how these things stack up against the best. Quote Link to comment Share on other sites More sharing options...
bnewport Posted September 1, 2007 Share Posted September 1, 2007 Between 1.25G and 1.5G (T7) at Road America. Trackpedia has data from 4 spec 944 cars there now so I figure it's real. http://www.trackpedia.com/wiki/Category:Porsche_944_Telemetry Quote Link to comment Share on other sites More sharing options...
Sterling Doc Posted September 1, 2007 Share Posted September 1, 2007 "In need of cash for a spec 944" Kevin - find yourself a cheap 944, get a cage in it, and come racing. THe suspension, and all that can come later. You could even win some money - as we have cash contingencies, and in the beginning, there won't be very many fully prepped cars...

kevintee Posted September 1, 2007 Share Posted September 1, 2007 Kevin - find yourself a cheap 944, get a cage in it, and come racing. THe suspension, and all that can come later.. As of now there is more than money standing between me and a 944, I will be living in Europe for the next 4 months (fly out monday) so that kind of throws a wrench in the plans. But when I get back in January I will be keeping an eye out the right 944 and then making it spec legal as soon as possible and upgrading as funds allow. But don't get too excited as I'm not NASA liscensed so I would need to do all of the HPDE events before I could race. Quote Link to comment Share on other sites More sharing options...
