Hey guys,
Well I've been thinking on what would be a real usable whp for a track NSX, from other threads I read seems like 500whp might be a liittle to much.
So maybe 400-450 would be a better number to work with.

And since the downfall of the NSX is it's lack of power...,But now with this problem out of the way, here is where my question rises, what would you compare a 400-450 whp NSX with, power/ratio wise?

F-430? 997 GT3?

2007 997 GT3 has a curb weight of 3053 and 415 hp / 298 tq. I have read that they dyno around 370 rwhp and 270 lb/ft.

A 2011 997 GT3 has a curb weight of 3075 and 435 hp. I imagine they are probably just under 400 rwhp and 300 lb/ft.

The F430 has a curb weight of 3196 lbs and 483 hp / 343 tq. Which may be very optimistic - shame on Ferrari.

So realistically, a 400 rwhp NSX should be very competitive.

If your going purely off power to weight...

Take my NSX for example.

2880 loaded.. if it had 330whp = 8.7:1 lbs/hp

GT3
3053 loaded with 370whp = 8.25:1 lbs/hp

Considering my car isn't weight reduced... i'd say you could easily set your cars power to weight up similar to that of a porche etc etc with very little horsepower.

More critical will be matching gearing and getting as much grip as possible under the car.

I run alot of short tracks in AZ and the GT3's are usually running about 1 - 1.5 seconds quicker in similar non race trim. Considering I have a measely 242hp, that should put a grin on anyones face :) Just lots of seat time, lots of tire, and decent suspension thats not 20 years old :)

Awesome info guys, really appreciate it.

I am having second thoughts about boosting the car right at this moment, I think I should of tracked it on stock trim a little longer.

I think I will run two maps, 300whp and 400whp so I can start with the lower power first and get a better feel for the car.

(I have only tracked the NSX four times, two of them with with blown suspension)

Just curious and off topic, but are any of you running a solution like this so you are less likely to loose an engine on the track?

I haven't tracked the NSX, but based on my experience with the FD making 430rwhp and spirited street driving with the SOS SC NSX I will have to say that I'm in agreement with that 400-450rwhp is a sweet spot for the NSX.

That baffle will help you ALOT, especially in banked sweeping turns. If your mainly on a flat track its not so much an issue but its cheap protection! WHY NOT!

I have quite a bit of track experience, mind you it was with an AWD car with a huge amount of power.
But the NSX is way more technical to drive and I love it, no PS or TCS makes it a blast to drive, my DSM had 500awhp even when it was abusive it was easy to correct and you were still confident because of the AWD system.

Batmans, I've done the baffle too (from sos)I think it's a no brainer.

Don't worry, I wasn't doubting that you had experience, I was just agreeing with his statement. I hear you on AWD to RWD though. I have been through over 15 DSM's, plenty with massive power (mainly used for 1/4). Then moved over to an E36 M3 as my first rear wheel track car. AWD/RWD/FWD can definitely all be fun on the track, just depends what mood you are in :).

And I agree, the baffle is a easy easy decision.
 
Power and weight are not all that is required.
The nsx can also be made to handle very well.

I can get around F430 and GT3's.

I am always amazed how well my 15 year old NSX can do against new cars.
Surely mine is not stock though.

Later,
Don

Just something to keep in mind, That f430 was dynoed on a dyno dynamics dynamometer. That is a road-force and typically reads 10-14% less than the same car on a Dynojet model.

So calling Ferrari's claimed HP rating a farce might be a bit preemptive.

Ferrari is NOTORIOUS for exaggerating hp figures.

I agree right there.

I have been track driving for many years now, but only 2 with the NSX. And man was it easy to DRIVE but difficult to drive at the LIMIT.

But once you get it right, holy hell is this car a capable platform. Add 40-60 whp and its able to keep up with most current generation sports cars.
 
He pulls from me on every straight, but I'm staying with him. If I had another 80-100 hp.... :cool:

ur picture of u in the avatar and ur arms dun seem to match. Bathe in clorox much?
 
Based on that video, the GT3 OBVIOUSLY out handles NSX's PERIOD (rolls eyes).

Definitely alot of driver skill there though if you ask me :)

The amount of drivers that can really utilize the 911 and have them outhandle NSXs and other cars are right there with seeing unicorns.

Basically, my point.

The amount of variables are too great... namely the driver. I have driven both and LOVE both. But mastering either car will require lots of time behind the seat. Or the other one will always seem faster lol

It's not just time behind the seat.

I've driven a few 911's and will say that you have to have all the basis covered:

1. seat time
2. A-game on race day
3. plenty of sleep
4. no sex the night before

With the NSX or a front mid-engine car like the FD or vettes you can do well with just the first one or maybe the second one. :biggrin:
 
A really good driver in a GT3 will run the above track (Putnam Park in IN) about 1.5-2 sec faster than me (1:20 vs 1:18). With a SOS SC, I think I could match.

Dr. Mario, in the video above, is one of the PCA instructors. But it's Dr. <---- enough said. :)

Always remember that the 911 driver has to look at his car every day and that it looks like 23 million other 911s whereas we have rare beauty to behold.
If you want to get round a track quickly get a single seater.
