questions about ctsc at drag strip

[snakey]

Hi guys...Ive owned a C5 and a few Vipers and now Im ready for somthing new. Im about to purchase a 1995 NSX but I have a few questions.

-How much dose a 1995 NSX weigh from the factory

-Are the 1995 gears the 4.06's

-The 1995 NSX Im about to purchase ( mn5) has taitec exhaust and a comptech SC pushing 9 psi of boost and well as a carbon fiber cold air intake. It is claimed to be 410 rwhp SAE on the dynojet at the rear wheels.

-What could i expect with this car at the drag strip in good conditions with a 1.9 60 ft and the claimed rwhp ET/mph wise?????


Thanks for any help. My last Viper was a 2003 SRT10 pushing 470 rwhp with a few bolt ons and ran 11.7-12.2 at 119-124 mph...Im not expecting those types of numbers. But will I even be in the same realm?

high 11s are possible with that HP.

My CTSC'd 1995 NSX puts down 350rwhp (6lbs of boost) and I was able to run a 12.6@115mph. I believe my 60ft was 2.2. 410wrhp should definitely put you into the 11's.

how can you tell by looking at the SC if the owner doesnt know if its running 6 or 9psi vs autorotor or whipple?

NSX's are good for 1.9 60 fts...I saw my buddy do it his second 1/4 mile pass ever...So you gotta figure that a 1.9 60 ft a 12.2 could have been acomplished. Still though...The 115 mph trap speed just baffles me. What track was this at and the DA if you remember

I made the pass at Sacramento Raceway in November of 2006. I'm not sure what you mean by "DA." The 115mph trap speed baffles you in what way? Below is a copy of one of my timeslips from that day (right lane). This one is of my 12.667 @ 114.137mph. My 60ft for this run was a 2.098. I can't seem to find the slip with the 115mph run. I raced a full-size Chevy pickup with a Procharger in the left lane!

In addition to the CTSC, I also have the JDM short gears, 4.55 R&P, Comptech Cold Air intake, Comptech Headers, and a custom 3" exhaust with hi-flow cats. You can check my profile for a list of my other mods.

DA means "density altitude" In wich your elevation and moisture of the air are put together to come up with a negative or positive DA...

ZERO as in "0" would be a perfect DA...

A guy at a sea level track on a 60 degree day may possiblt be close to a 0 DA.....

Lets say that in a "0" DA a bone stock NA1 will run a 13.6 at 104 mph...

Now transport the same driver and NA1 to a track were the elevation is 2000 ft and the temp is 75 degrees and this same driver/NA1 will run a 14.0 at 100 mph due to the "DA" being + 2500 feet....

Then have this same driver/NA1 go to a track like ATCO on a night were the DA is better than perfect ( better than "0") and yes it dose happen. Sometime the elevation can be below sea level and the weather can be perfect bringing in DA's in the NEGATIVE 2000 range ( expressed DA - 2000)

Now this same driver/NA1 will pull a 13.4 at 106 mph in this DA...

differances in DA are the main reason why numbers vary so much from 1/4 mile track to 1/4 mile track..

2 guys with the same skill haveing NA1's that both dynoed 230 rwhp can easily be a 1/2 second apart from each other due to differances in DA's at they're perspective tracks...

One could run the 13.4 at 106 while the other runs the 14.0 at 100 mph despite the 60 fts being the same and car/driver skill being the same...


This is why I asked you what your DA was on the night of your 12.6 at 115 pass.

Gotcha! Well, I did a google search and Sac Raceway is approx 52ft above sea level and the temp for that day was a max of 69F, min of 53F, and a mean of 58F. I punched in all of that info into a Density Altitude calculator along with the dew point and altimeter setting (from the farmers almanac for that day) and got a Density Altitude info below. I know, I know.....Geek check! :biggrin: Isn't the internet great!

OK got ya...Pretty kool of you to actually go check everything out...Seems like you were in pretty good conditions overall..

At a ZERO DA you would have been around 12.5 at 116 mph...I suppose for a 350 rwhp vehicle this isnt too bad but Id still think that a 2900 pound vehical would be faster with that kind of power...I guess it's just the lag in the lower rpm's.

But Im sure when she's at 5000 rpm's you get the full feeling of a 2900 pound 4.06 geared 350 rwhp vehical ( wich should be a good acelleration rush) and probally very fun.

With the weight ( 2985) GEARING (4.06) drag ( .32) THIS THING SHOULD FLY WITH ONLY 350 RWHP. 120 MPH TRAPPS SHOULD BE OBTAINABLE...

Well, the targas are actually ~3150 lbs. If you factor in the driver weight (220lbs for me) you are looking at 3370lbs. I also have the 4.55 R&P. When coupled with the supercharger I find myself hitting redline pretty quick. I kind of wish I had the NSX-R 4.23 R&P.
I've also done some weight reduction, so my car is probably tipping the scales at a tad over 3000lbs. Maybe if my lazy butt got off the couch and in the gym and lost a few lbs I could shave off a few more tenths in the 1/4 mile. :biggrin:

The list I posted above were for a NSXT..This said 2985..Another list I found said 3010....Were are you finding this 3150 number. I beleave that's for the newer NSXT's...
