my 1/4 mile runs VS M3/M4/997 GTS, etc

My times compared with other higher HP cars at the same track on the same day. My NSX has a curb weight with me in the car of 1270kg/2800lbs and 303BHP, runing on 255/40/17 Potenza RE050A 2 years old. It was a hot day, driven on a airport roll-field. Surprise to me is the Z4 BMW, cause it has only 350hp and the owner claims it is completely stock. I picked some cars out which are in my time window. What do you think? Many sites claimes the NSX with my weight and power should run mid-high 12s....but compared to the car at this track, the difference is okay I think. Sea Level is 500 meter

My best was 13,338 @ 170,5kmh/106mph /// 60feet 1,649 /// 1/8 mile 8,635 @ 131,5kmh/82mph

Porsche 997 GTS with PDK tranny: 13,106 @ 174,76kmh/108mph /// 60feet 1,694 /// 1/8 mile 8,563 @ 135kmh/86mph

BMW M4 12,913 @ 184,5kmh/114,5mph /// 60feet 1,868 /// 1/8 mile 8,655 @ 143kmh/89mph

BMW M3 4.0 V8 13,309 @ 175,61kmh/109mph /// 60feet 1,815 /// 1/8 mile 8,7778 @ 86,5kmh

BMW Z4 35is (3ltr turbo) 12,949 @ 173,91kmh/108mph /// 60feet 1,646 /// 1/8 mile 8,3399 @ 136,11/84,5kmh

Audi RS6 13,146 @ 178,66kmh/111mph /// 60feet 1,854 /// 1/8 mile 8,733 @ 136,88kmh/85mph

Nice times, what mods was done and was it done with the big wing?

Having the DF replica NSX-R wing. But here is a full history of my car: http://www.nsxprime.com/forum/showthread.php/189800-The-quot-austrian-type-R-quot-NSX

I'm surprised, because your car should be allot faster, you likely did not launch properly, since although you wrote 1.64 on as your 60ft this may be confusing, since all your other cars say RT for "Reaction time". The 60ft time is the most important/crucial factor and variable in drag racing. Please check that is your RT or 60ft because that 60ft is extremely fast for street tires almost impossible on a NSX, I'm going to make an assumption that 1.64 is your RT and not 60ft, and that your true 60ft may have been a bad pass there because with your power and weight and that low of a 60ft would have put you into the mid/high 12's without question and also your 8.6sec 1/8 mile also does not represent an incredible 1.64 60ft either, since a 1.65 60ft would equal under 8sec 1/8th of a mile, thus your actual 60ft time was more likely around a 2.2-2.4 60ft, which means your car will run high 12's if launched properly with a 1.8 60ft. for reference The best 60ft launch I've seen posted on prime over the years was 1.7sec and that guy had allot of experience. The NSX chassis just does not launch well. Some street supras can pull 1.5's to 1.6's and that's very aggressive.

for reference, I had not been to the 1/4 mile track in over 5 years untill last week I ran a 12.91 @ 106mph with a very bad 60ft time of 2.03, and a 1/8 mile of 8.379 which means if could have matched your incredible 1.64 second 60ft I would have ran at least 12.5 or better in the 1/4
(that does not factor in that each .1sec off the 60ft equals up to .2 off the 1/4 due to increased amount of time spent at high speed at the end that gained/traded from time spent at lower speed in the beginning which could translate to 12.4-12.5)

Car is 2500lbs and the Dynojet says 279rwhp

the car is good for 12.5 to 12.6 all day if I get stickier rubber and run a normal 60ft of at least 1.8sec, Problem likely was the 5 year old 245-45-17 continental contisportcontact 3 that refused to provide any traction at all and I did not do clutch drops for launch nor will I anytime soon. I don't want to put drag tires on and abuse the car unnecessarily, but It's nice to know the car is capable of 12.5-12.6's by just improving (abusing) the launch by .2sec to normal standards

I'm not really into drag racing at all, but do understand the principals and variables pretty well.

hi! Sorry for the confusion, the times are all 60feet times - I have edited the thread. The total times are w/o reaction time, those were not added to the final time. So I had 1,6 feet times, which is good I guess. Compared to the other higher HP cars the 1/4 times seems okay, cause all I listed have 100+ hp more to the engine, except the Z4 which has 345 stock. I think the NSX chassies is very good for launch, cause the weight is more in the rear which is good for grip.

I did 4 runs and my 60feet times are 1,646; 1,637; 1,668; 1,641

The M3's best was 1,446, The Z4 and the Porsche did also 1,6xx times

But right, something is not matching up here. My 60feet times are better than yours and the final speed is equal....so I should have gone faster thru the quartermile....in theory

The 2nd thing is I raced 3 times at an 1/4 mile race the past 3 years where the street is 9% uphill.
I did 14,7 in first year, a 14,6 in 2nd year and a 14,3 last year. 100kg less car weight from 1st to last year

The last 1/4 mile on a streight I did 7 years back with a 13,3 and 169kmh...car was 100kg heavier with also heavier rims at the rear (OZ Ultras 18inch vs ce28n 17inch now) .....so something is wrong here, maybe the timing of the different tracks, maybe the 60feet measure point is not at 60feet and they installed the point of measurement wrong?

I totally agree that your car should be faster in the 1/4 than 13.3, I was not trying to compete with you although our power to weight is close and we should run similar times, only simply showing you for comparison that your your data is misleading you to understanding why your time a bit slower than expected for your power to weight.
Please research and you will see all those 60ft times are impossible on any of those street cars
No M3 can do a 1.446 60ft not even on drag racing slicks with a professional driver.
The NSX will not do 1.637 on street tires
these type of 60ft times your'e mentioning here represent prepped drag cars with experienced drag racing drivers on drag tires that run 10-11 second times.

here is a good thread most people are around 2+ 60ft some 1.9-1.8 and very few have done 1.6-1.7 and ccathy's best was a 1.56 and 10.39 1/4 and 600+hp but all those guys are on 285 or more width drag race tires which are much stickier than road racing track tires and they both have a good bit of drag experience. Your saying you ran faster than them on less sticky 255 road racing street tires and half their rwhp which is just not possible just like M3's can not run that low. That M3 would have to be running 9's with 1000hp and massive drag racing slicks to do a 1.4 60ft and would break drivetrain parts every other run. If your 60ft was accurate you would have ran under a 8 second 1/8 mile and mid 12 1/4
http://www.nsxprime.com/forum/showthread.php/159401-Post-your-1-4-mile-times

the track must have something wrong with their 60ft measuring device.
your car should run mid 12's
Is your 303hp at the hubs or at the tires?

What is the elevation at the track?

about 300 meter

Ran a 12.92 in my NSX. headers / exhaust / NSX-R gears and standard weight. 1991 with 90k miles. Sumitomo HTZ II's 400 tread wear street tyres. Consistently. Clutch at the time was OS Gilken twin disk.

Yea I think u should be in the 12.XX range, I ran 13.5 @106 on my 97 NSX-T, with exhaust, high flow cats and intake. Now just got turbo on, can't wait to see what difference will be,so much more fun to drive, haha
