I havent seen one break into the 13's at those altitudes, best ive seen was mid 14's. S2000 also gets affected at higher altitudes pretty badly since the higher the altitude, the later vtec will engage. At high enough altitudes, vtec wont even hit until 7k! :-(

that's interesting as Sakred said he was still able to get a 14.2 either stock or with just his intake. maybe the 350Z fares better than both the M3 and S2k then.

sakred have you ever run any S2000's at that altitude?

Choppa

Doesnt the M3 engine (s54) have a similar type of valve lift to vtec? Wonder if this gets affected by altitude.

Wisconsin S2k

yes it does. i forgot what the heck BMW calls it.

i have ran s2ks at that same track i have slips i can show you. the 14.2 was done on a stock 350Z this was an 03 modle i now have a 05 which is slower for some reason. or maybe i forgot how to drive . the runs i have slips of was a member of this forums and s2knvegas friend. i forget his name. he was a really cool guys. he drives an AP2 im not sure of his mods but i think his best to my knowledge was a 14.5

Hey hey thought I'd join in the convo here. Great vid by the way Sakred.
Wisconsin from my experience at lacr I would say the S is very much effected by high altitudes. At about 3000ft elevation, and as bad as the weather is there the car always feels nothing like it should. VTEC defenitly does engage later. I am not sure when on mine, but I believe for 9K it was engagiong at about 6.5-6.8(correct me if I'm wrong 9K). I have ran sakred there twice, and we went 1-1. My best time there so far has been 14.5, but I have had a friend hit 14.4(I guess he went on a good night). As bad as the track is, it really is a great track because by the end of the night you could have gotten in atleast 20-30 runs.
Sakred's car is really quick, I've ran other Z's there and have beaten them all by 1.5-2 cars. I beat sakred by about half a car, and the next run he did the same to me.

I do have a couple mods though, so we'll see how they help out next time I'm out there. I'm thinking of buying the mugen cooling mods to help my engine stay cooler in that desert heat.
