Small Vids & Pics of a friend's NSX -> View my last post :D
Hi guys,
a friend of mine bought a NSX ME-Edition (modified by a german tune house), we tested it and it's light modified, bur efective.
The stuff it has is a Fujitsubo Exhaust, K&N intake, some Koni Coilovers and S2000 rims (wich looks awesome)
Here are some pics of the car:
Pic 1, Pic 2, Pic 3 and Pic 4
And some Vids:
1st and 2nd gear aceeleration
Going from 4th to 5th gear ate 245km/h
Going uphill at 280Km/h Vid 1 and Vid 2
Getting to 310 Km/h straight (not downhill)
NSX passing at 320 km/h almost cutting off the 5th gear at a downhill (nearly missed it)
Nice drift very bad filmed
This NSX gets to 300 km/h very easy, taking a little while going from that.
PS - The videos were recorded using my Nokia 6600, so, you need Quicktime to view them

Hmmm... 300 kmh = 186 mph. The stock '91-01 NSX tops out at 168 mph, the '02-04 at 175 mph. Either would need 50+ horsepower to reach 186 mph, and the mods you list won't get you there...

The second pic makes the S2K wheels much more attractive on the NSX. And yeah, I'm thinking there's got to be more hp added than what you'd typically get with the parts mentioned. Any internal engine work?
In any event, thanks for the post.

Hi,
We believe the car is completly stock, engine speaking.
about the speed, we all know that all cars are capable of more speed than what the factory says, right?
and you better than me, know that little mods like intake and exhaust, improve greatly the performance of a NSX.
but i'll have more info in a near future, including a new NSX bought by another friend, but this one already have a complete racing exhaust (the sound of it is superb), and this other friend is going to invest in his NSX...he want to make it fly...

Not according to the magazine tests, whose results all pretty much agree on a top speed of around 168 mph.

Greatly? No (as Ponyboy mentioned). From what I've seen, there is almost no difference between horsepower with K&N filter and stock filter. I don't think there is much to be gained in the exhaust, either. Horsepower gains from most exhausts seem to be around 5 HP (approximately 2% gain); Even the best ones are no more than 10 HP. Then again, I'm familiar with that exhaust. Also, I'm not sure if by "exhaust" you are refering to what's normally considered the exhaust (everything after the cats) or headers/exhaust manifold (the stuff between the heads and cats).
Anyway, the S2000 wheels do look nice. In fact, I've wondered if any NSX are running these wheels. With those width wheels, what are the tire sizes?

Re: Small Vids & Pics of a friend's NSX (ojas)
by exhaust, i mean everything but the headers. I'm talking about no cats and a Fujitsubo muffler system. The K&N filter was instaled and air redirected to it.
A couple of friends of mine have NSX stock from the front to the back, and by no means they accel. like this one. It's very quick to 300km/h.
Just for experience, this NSX was compared to a friend's CBR 900RR, last model, the 954, completly stock.
At 150km/h roll on, the NSX in 3th gear with VTEC off (just for a thin hair), the bike jumps ahead, almost no distance (the NSX couldn't go to it's tail without touching it), and before the 3th ended, the NSX is already side by side with the bike. But then, there was some maintenance cars in the side of the high way and the NSX slowed to 160km/h.
Our friend on the bike, had no mirrors, so he couldn't see the light signs we did to start the test again, and he almost vanishes (we could only see a small red light), with the bike at 292 / 295 km/h in the straight. My friend says "what the hell, let's try to go after him, not if it is possible" and start accel de NSX in 4th at 160km/h... not a mile ahead the NSX was at 310Km/h. from the initial accel point to the point the NSX passes the Bike are about 7km, completly straight with 3 lanes completly empty of cars. The NSX passes the bike in such a way, that our friend told "Jesus, i was at 295 and saw something red passing me by the left, i could even see a thin smoke layer arround the car like a wind tunnel test, in 30s i could't see the NSX anymore"
Attention that this test was on a bridge we have here, that is 13km long, completly straight, 3 lanes and with visibility from one end to the other. No cars, except those maintenance trucks in the start (wich is a light corner).
About the tire sizes, i'll go check them out, but i think is 205/45 r16 in front and 225/40 r16 in the rear.
about the speed, don't forget that a stock car with a lower suspension have a better aerodynamic. but i'll run the GPS in it and tell you the speed difference in it and the speedometer.
PS - just for fun, see the video in my signature (my car is the black civic sedan), and follow the adress of the initial vids that i posted of the NSX, to find some vids of the Tacho of my car accel... goes nearly 10000rpms...as i said, just for fun. later i'll tell how the comps. between my car and that NSX were like

Exhaust only isn't going to get you to 186 mph. However...

That size is about 7 percent smaller (in outer diameter) than stock. So 186 mph on the speedometer is going to be about 172 mph actual speed. That's a bit closer to reality.
There are other sources of speedometer error as well. Speedometers are usually designed to read 1-2 percent high. Differences in tread depth between new tires and tires worn down to the treadwear indicator bars can be as high as 2 percent. (That's why magazine tests use calibrated measurement devices instead of relying on the speedometer.)
Inclines can affect actual speed. (That's why magazine tests are held at test facilities that are level.) And wind can be a factor too. (Magazine tests report a two-way average.)
The magazine tests of a bone stock '91-01 NSX on a level test facility showed 168 mph top speed two-way average (one magazine was as low as 164), and tests of a bone stock '02-04 NSX showed 175. Exhaust without headers might boost that by another few mph, intake won't have any effect.

Re: Small Vids & Pics of a friend's NSX (UnhuZ)
I'm sorry but stock '94+ NSX wheels look much better than the S2k wheels. Maybe the car was on blocks when you ran it to 300kmph. Oh well.

Remember, the last mark on the speedometer is 290 km/h, not 300 km/h. Take a look at this still frame from the "310 km/h" video. The speedometer is past the last mark (290 km/h) and is indicating just under 300 km/h, 10 km/h less than what you claimed.
Perhaps all the numbers you are quoting are off by 10 km/h. This, combined with the errors nsxtasy mentioned, make these speeds more plausible.

Re: Small Vids & Pics of a friend's NSX (ojas)
You're right, just because my Nokia 6600 only record a few seconds and the recording ended before it reaches the 310.. but you can view the foto i've shot of the speedo right here. You can see the 290 mark and the vanishing scale to 300 and the needle just were the 310 mark would be... and i can assure you (no need to bulllshit, i'm in this car thing just for fun) this is at straight and this speed is reached in just a 2km starting from 2nd gear at 80 km/h.
I just hope to do a better footage of it with a real camera so that you can see how the car go up the speed scale.
About the tires, when i have the right sizes, i'll post here..
PS - no comments on the EG9 video??? :D:D:D:D:D:D

Re: Small Vids & Pics of a friend's NSX (Ponyboy)
ehehe, you're right, and i did post it in the EG Forum...
i only said something because i've tested my EG9 with this NSX, and from 20km/h in 1st gear to 220 km/h, when my 4th ends, the NSX only goes some2 cars ahead of me.... from that speed forward, it's carzy, i look to my speedo marking 270 and don't see the NSX anymore. The accel that the NSX have from 220 forward causes that we enter in a 3km straight and i'm at 270 and barely see the red lights of the NSX.
it's awesome .... no words...
:D:D:D:D:D

Re: Small Vids & Pics of a friend's NSX -> View my last post :D (UnhuZ)
ok, here it is an update on this NSX
Sound Clip
This is a sound clip (save it and open with quicktime)
What you're about to hear is:
NSX in 1st gear at idle rpm, slower then this is impossible.
2s -> changed from 1st to 2nd
6,5s -> changed from 2nd to 3rd
12s -> 180 km/h
13s -> changed from 3rd to 4th at 200 km/h
28s -> changed from 4th to 5th
28s -> 1.2km at 245 km/h
49s -> 280 km/h
60s -> The recording ended just as we reach 300 km/h
Not bad, for this NSX, right?
this was all done straight (not downhill)
PS - The rear wheel size is 225/50 r16, i think it is the stock size, right ?

Top speed in third gear is 114 mph (183 kmph) at redline; the rev limiter would cut in a few mph/kmph above that. 200 kmph in third gear is impossible.
This is more evidence that the speedometer may be seriously inaccurate.

Re: Small Vids & Pics of a friend's NSX -> View my last post :D (nsxtasy)
er.....
the rpm have the redline at 8000 and cutoff at 8300, and the speeds i mentioned are what i read in the speedometer
but with the soundfile, you can ear the gear changes, and then see if it is quick or not looking at the seconds, whatever is the speed that i read.
The speedometer indicates the following speeds (the ones i remember):
3rd -> 200 km/h at 8300
4th -> 245 km/h at 8300
5th -> about 320 at 8200 (didn't cuttoff by a thin hair)
PS- i'll be posting here later new infos and fotos of a NSX that a friend of mine bought yesterday. The rear wheel size is sick :D:D:D

this 320 was downhill to see where would it stop :D:D:D:D
but that foto i posted in the first post of this topic (310 one) is straight and the needle slightly past 8000.
As i said earlyer, no need to bullshit from me, i just want to learn from you guys all i can in this NSX world.
One thing i discovered...the intake/exhaust/TB/chip pack is cheaper then for ITR...with best absolut values added.

Don't forget that you use a 92 octanes gasoline. We use BP ultimate 100 octanes gasoline... That´s why our cars are faster.

First of all, most of the United States uses 93 octane for premium fuel, and Sunoco stations in the Northeast have 94 octane available. Only the far West does not have 93 generally available (and has 91).
Also, your octane is measured on a different scale than ours. Japan and Europe usually use RON (research octane), which gives a higher rating. In North America, we use the "anti-knock index" which is (RON+MON)/2 (where MON is motor octane). So our 93 octane could very well be as high, or higher, than your 100 octane. In fact, BP Ultimate is also available in the States (it was originally developed and marketed by Amoco - Standard Oil of Indiana - before its merger with BP) and is labeled here as 93 octane.
You can read more about octane ratings in this section of the Gasoline FAQ. You'll see the note about many European gasolines failing to have MON as high as 85. Remember, (100+85)/2 is less than 93.

Nice try. Try again.

Haha...I'd like to see an answer for that one.
To the original poster, no one is doubting your account per se just doubting the accuracy of the equipment. Make sense?

Re: Small Vids & Pics of a friend's NSX -> View my last post :D (Ponyboy)
ok, nsxtasy, you made me go in a deep search 
RON and MON explained
From this article, i could see that even with the formulas for converting American Octane index to european, they cannot be compared directly, because of the zillions variations that may be in the fuels...
i learned that there are some fuel componets that may influence Octane value. And by the fact that American standards are surely different from European's, the fuels are surely different in their composition.

that's not the correct formula, nor is the result of that formula a direct octane index. The correct Formula is RON + MON/2 wich gives us a value. That value measures somewhat the real performance of the fuel. But as the article says, the RON and MON are affected greatly by fuel components.
Man, i really enjoy deep conversation, other than "mine is bigger than yours" talk, thanks for that nsxtasy
Ponyboy:
I know that :D, and sure, the instruments may have huge error differences, and i use to measure with GPS in the same conditions to have a more accurate comparing value (not 100%, but close enough).
But just help me on something, what is the real rpm that an NSX cutsoff (not redline) and what would be the real speed at the cutoff in 5th?
i made some calculations in Excel with the gear ratios, rpm and wheel sizes and reached about 310 real speed (some 330 on the speedometer).
