Whats the best time anyone has run or has proof of somebody else running (Not just some lame story of hearing or maybe seeing acar that "looked" like an nsx) ....
The 1/4 mile. If any one is in the 10's. Cough up the timeslip, because I'm about to claim the fastest street NSX if there aren't any Challengers. You give me proof, I'll show you mine. - Timeslip - I'll video it if anyone requires further proof.
 
David, Where are you!? My car runs in the mid 12's (for now....2.0 60ft agghh) but I know that's nowhere close. What is that twin turbo beast running?

Why don’t we categorize the results into:

1. Fastest Normally Aspirated
2. Fastest NOS
3. Fastest Supercharged
4. Fasted Turbocharged
5. Fastest.

This way people can evaluate the best way to modify their car for ¼ mile performance. Remember, that power adders (NOS, SC, Turbo) place you in NIRA Power Six where times fall in the Nines!

Here’s my proof for my Normally Aspirated 98 Coupe with CT I/H/E, Test Pipes, CT Clutch, and Nitto 225x50x16 drag radials. Click on the following links and scroll down to Comp 6.

Can you guys also post the weight of the car and the tires you you ran the time on as well? The coupe is supposedly ~200 lbs lighter than the T. This definitely affects the trap speed, and the tires dramatically affect ET. Unfortunately, I cannot find my timeslips so I won't comment on my times, but I would like to see how your cars compare to mine.

My mods are quite large. Mostly weight reduction. When I race I remove the Passenger seat, and Front sway bar for more rear weight distribution. Among a THOUSAND other things I've removed or changed in the past. - Just removing the cats saved me almost 30 lbs.

Current Mods for speed, not handling or Useless pretty stuff that I have much of also.
A two stage NOS and Nitrous X kit. How much horsepower in each? More than you'd ever put in your car. Dual bottle warmers.
A walborough 255Lph intank pump
An RPM window switch to make sure nos is not flowing when I don't want it. (Adjusted stock timing) Colder spark plugs only when I race. 104 octane fuel. Custom welded Borla exhaust. Custom made intake by myself. Stock internals. I drive a 91 coupe that weighs less than probably most anyone, and I run it with a centerforce clutch that slips the whole way down on a set of e.t. STREET DOt approved tires. Runs 10's. I want to see slips! (1/4 mile time slips) By the way, Don't launch extremely hard, baby it at first, then bang through the gears like you stole it. Gears can handle it. CV joints CAN"T. - 1.75 60'.
 
WOW! Dang Dave. (Schwartz)
a 12.5 at only 111mph!?

You know how to drive the hell out of that thing! That's stickn and movin.

My mph is 132. Times are still in the mid to high 10's. I have to upgrade drivetrain and clutch to do any better

NSXLR8, Very impressive times. Sounds like you are very proud of them as well. Are you running a wet or dry shot? I assume a wet/direct port for that size shot. Any kind of fuel management? How do you adjust pressure w/the larger in tank pump to keep from a rich condition at idle? Stock injectors and internals? How did you adjust timing? 1.75 60 foots "babying" the leave? Hate to see what you would do on a hard leave. 132 mph? I find it hard to believe that stock internals could handle the amount of nitrous it would take to run those numbers. Please don't take this the wrong way and I apoligize for the 20 questions. Just trying to piece this all together. Dave,(Schwartz) we have talked drag racing (NSX's ) quite a bit, any thoughts?

Yeah, I'm sorry. You guys are being very cool about my loud talk. I'm just sick of so many people putting down NSX's potential, even ones that own them! I have good friends that own race shops, so parts aren't that hard to obtain - (Especially the knowledge of what happens to other cars) I've simply compared the horsepower potential to the Supra. Stock internals handle 800+ hp! Why couldn't the NSX handle 600? My shot is a wet shot. The pump is much larger and with it I had to change to an Aeromotive (Larger) Fuel pressure regulator. It keeps the pressure in check. I own a shop manual that tells you everything, including how to change the timing. More involved than a 5.0 mustang, but really not that difficult. To be honest.... the NEW head gaskets was letting the coolant system pressurize, (But I was ready and already had the catch bottle set up) (Weak link in the engine I guess)
My 60' is actually SLOW compared to my friends new C-5 Vette - 1.5! (He broke his axle (rear end) about the 10th time he's launched like that.)
 
My first shot is 150hp my second is 100hp so, you're looking at an extra 250hp @ the wheels - 550@ the crank. Remember - extremely cold spark plugs (Foul out if used w/out nitrous), larger fuel pump, 104 race fuel.
 
NSXlr8, I used CarTest to calculate 1/4 mile times and found that you would need about 570 HP and 510 lb ft or torque at the crank and 2500 lb weight to generate 10.5 @ 135 MPH. With 550 HP at the wheels it seems correct that your car would be in the 10's.

However, since you have asked everyone else to substantiate their claims, how about letting us see your time slips and dyno runs.
I'm sure with that amount of power you have done some dyno tuning. You should also be able to point us to track results posted on the web.

Dave.

What is the technique for a 2.0 60ft... heh I would be happy with a 2.1. I went to the track on sat and the best I did was a 12.53 @117 with a 2.3 60 ft.... Help?

What mods do you have? What tires are you running? What is your current technique?

If I know the above, I could make some suggestions.

I have a 91 with intake, Exaust, Headers, and 100shot. I run a NSX modified ceramic clutch pack. The tires are 285/35/18 nitto nt 555R The car now either spins or bogs. My best 60ft was a 2.2 . This was done by lauching @ 3k.... the car bogged and as it started to accelerate I hit the nos .

P>S> I still run all the original gearing

I find that when I bog I get 2.0 60' times. If I bog slightly I get 1.8 60' times with 225x50x16 Nitto 555R's. If I spin I get 2.3 to 2.4 60' times. Lately, however, I have found that a smoking 2nd gear burn out with the Nitto's provides unbelievable traction. I launched at 5500 RPM and bogged! So my first suggestion is to make sure you really heat up the tires.

Next, I think waiting to hit the NOS after the launch is smart, however, I would experiment with and without NOS after heating up the tires. I don't have NOS on my NSX, but I did on a Corvette I used to own. With that car if I used the NOS off the line I would spin the tires all the way through first gear in a Turbo 400 3-speed automatic! With the NSX, however, we have about 57% of the weight over the rear wheels, therefore, we can generate a lot more grip than a Vette. So you might want to try it.

I would be curious to find out how nsxlr8 launches his car. I think by "babying the launch" he means he comes out with NOS but at very low RPM (1500-2000) so that the engine power does the work and not the flywheel inertia. By the way, if you don't have a light weight flywheel, you will find it difficult to control wheel spin.

Thanks for the help..... I will try these and get back.....
 
hey guys. Sorry 'bout the absence. I've been installing a nitrous kit in my friends NSX all weekend. (For Free!!?) man. I forgot how much work it was. I did my mods one at a time. Single stage kit, then heater, then purge, then second kit. He had the order all ready for me ( I also sell Nitrous Express kits ) Single stage, Heater, Purge, Remote Opener) Anyway. In answer to your computer simulator. WHAT!!!? I think somethings screwed up there buddy!. A perfect run is in the 9's at that MPH. Go ahead and look up some in mustang 5.0's magazines. They have many times and mph from all the competitions. The ones that hook up will be a high 9 @ 135. Ari Yallon (A racing acquaintance of mine) Runs an RX-7 turbo. When he's not runing NOS. He ran a 10.4 @ 134MPH. - He uses a Stock transmission so he actually TAKES IT EASY between shifts. Nines ARE possible at those speeds. a 10.5 is not so difficult to beleive even with stock gearing. (Remember NOS adds Gobs of torque which negates some of the inherit flaws in our gearing. My gearing you ask. STOCK. I will get my slip and post it within a couple of days. Unfortunately, I don't have video yet. But it's necessary to have to PROVE that slip goes to MY CAR. That's what I expect out of anyone that challenges me on this also. (Faster NSX) My car should be out of the shop in a couple of weeks. (Someone ran into me) I will go out to Houston Raceway park and have a friend Video it all and put it on the web for me. (I haven't gotten into computers as much as I have in cars ...Yet)
 
Nope no dyno tuning. Just check the plugs on each run and keep going. I run at HRP (Housotn Raceway park) Friday nights are test and tune nights. No results. (I think the best that might be posted on the web would be an event I ran out there in February? It was import drag? Nopi? They change all the damn time. They're now Summit or soething like that. I know there's Two sanctioning bodies for Imports. The competition is MUCH tougher up there in Englishtown. Seems like EVERYONES running nines. I only ran an 11.6 @ 120 mph. (I had stage II. Too scared to use it! (Stock fuel pump and only one heat range cooler plugs)) I've removed 150 lbs of weight since then - (Don't ask, I don't want to get flamed by everyone) My weight? Honestly, I'm not sure anymore. I was @ 2850 last year. About only 5 gallons of fuel in the car. (Me out of the car.) I've removed um well ALOT since then.

Your talking about cars with suspensions set up for drag racing (90/10 schocks, lift kits, etc.) and running slicks. Not cars with road racing suspension and DOT street tires. By the way, in NIRA with NOS you'll be running Power 6. In that class, you need to be in the nines to win. It is for that reason that I haven't used any power adders.

Dave.
