ScienceofSpeed Supercharger?

Yep First mod on my car.

Actually, I always believe that the NSX is too silent for a Sports car. Also, I always wanted a Tubi, but Bash is not getting raid of his Tubi, therefore the next best option is the GTLW.

Hey Chris, are all these cars OBDII? Dave's (Biobanker) car is OBDII and NSXCessive is also OBDII. I'd think that if you were using a piggy back OBDII it would be no problem passing emissions with just a little tweaking of the AFR.

But what about OBDI or cars using a full stand-alone EMS? The EGR must be configured or there is no way the car will pass emissions due to excessive NOX output.

We have passed both OBD1 (1991-94) and OBD2 (1995-2005) through tail pipe emissions tests in AZ which per Jim have the same standards as AZ. It's not too difficult with proper tuning.

Hey Chris so would you agree its quieter than the old whipple? I've heard the whipple and I have to say its a bit loud when winding it out... but I thought it sounded awesome.

Can you comment on the loudness with the intercooler installed on your charger. Is it any different louder or quieter with out without it?

We'll give Bram some ear plugs... :wink:

Yes, the Whipple is the loudest twin screw I have heard. The compressor we use is the quietest twin screw I have heard. You can not hear it during idle and low load driving. It emits a very light growl/whine sound under wide open throttle. I have this in my own car, and I love the sound.

The problem is that OBDII cars need to plug in here - so the piggy back is our only option.

That said, if your very good friend who is a tester is not comfortable putting your car on the dyno because its too low <ahem> OBDII cars can sneak through with a sniffer test only and wont have to plug in.

But you need to be "lucky" with your tester.

Bram, if you drove my car for 5 minutes and hopped back in yours, you would wonder why only three of your spark plugs are firing.

RED CAR FOR SALE!!!
 
Yes, our supercharger system maintains OBD2 compliance as well. It passes by way of OBD2 compliance as well as emissions output. Simply put: emissions compliance is not an issue for any year NSX with our supercharger system. Hope that clarifies this.

Two things.

1. Bram can't fit in your seat
2. Red car would be supercharged, not sold.
One more thing...
3. Dave's car is awesome - it's what an NSX should be.

Bram will take one. But dont tell him that he is getting one; it is a surprise. We need to steal his VISA asap.

How soon can you ship it?
 
Hey Bram I got an idea? u want to keep it NA right. Well a SC gives about 100hp right, OK so about 100 lbs is obout 10hp right, there u go remove 1000 lbs from your NSX and it should be just as fast and better on gas and it will be NA:biggrin:
 
Nonsense!

You can get there easily.

Take off the wheels, 250lbs
Remove seats, 150 lbs
Who needs gas? 130lbs

we ate half way there and the heavy brakes, steering wheel, airconditioning, glass, targa top, carpeting, radio, cigarette lighter, spare, transmission fluid, carpets, and everything else, is still on the car.

You're right. NA is the best.

That's the NASCAR approach. You could go the BMW F1 way, and get the driver could always loose 50 pounds and that's worth 5hp at least! :)
 
Bram! I'm not too sure it's a tough call to sell my CTSC whipple.
I was thinking about? hp/weight ratio. A stock NSX has 290 hp and weights around 3100 lbs. divide into each other u get 10.6. 1 hp pushing
10.6 lbs. with SOS SC making big power and SOS selling lite weight products. I was thinking is there anybody in the low 5's. We now have an NSX making 420 RWHP with around 15% loss is making 495 hp at the fly and lets say a body weight of 2950 lbs. u get 5.9. I guess anybody in the low 5's or even high 4's would own one incredible NSX.

Dude, that engine has to weigh in close to 1,000lbs... just toss that overboard along with everything connected to it. NA is best!

I'm at 412rwhp and 2950 lbs. I don't think its a 15% loss more like 12% or 13%. Still in Vegas I've trapped at 120.5 when it was still in the 90s. My 60 foot was not that good so it was only a 12.01. I think a 420rwhp at 2950 in good air should be good for 123-124. It's about 200 lbs and 30rwhp less than a C6 Z06.
 
Easy guys... SC or NA it's all good, in fact every NSX puts a :smile: on everyone who owns an NSX right? right. I was just thinking who is pushing into the territory of super exotic like the Saleen S7 TT 2950lbs 750hp = 3.9 crazy low # thats all flolks. Every NSX rocks PERIOD.
 
I dont know if you have done anything or not yet but i will give you my two cents. If you had a supercharged anything vs a turbocharged same car, and they both had the same boost (8psi) the turbocar is faster and more reliable, easier to tune and maintains the good fuel mileage of the stock motor. If you always want more power(which you will) it is much easier to get more out of a turbo than a supercharger. I presently have an nsx that has been tuned by UMS here in phoenix and has 501 hp at the rear wheels on the street tune and 610 hp on the race tune. The car is as easy to drive as stock and gets the same fuel mileage as before. I have owned supercharged cars and motorcycles and turbocharged cars and will only turbocharge my vehicles in the future. This next statement will cause some controversy, but get in the new age and turbocharge superchargers are old technology. That is my opinion (no matter how stupid others may think it is )and I am entitled to it. Contact some guys who have made the change and I am sure they will agree.. LIVE BIG and remember small
 
Hey Brian If your turbo NSX is making 501 rwhp in street trim and passes emissions WOW u own one incredible NSX If it did not pass emissions I still say cheers Good job.
 
Just returned from a trip and noticed some questions concerning the SOS supercharger

!-Whine- you would be very surprised how quiet it runs. No noticable whine.

2-Emmissions-I have a 94(obd 1) and passed emmissions with a fcon pro.

3-I have owned many a car, some with turbos and some with superchargers. While I do not wish to debate which unit is better, I will say without reservation the SOS unit is exceptional.

After 15 years of driving the NSX, I re-iterate, the car now performs the way I always imagined.......without question!!!!

Hi Guys, I am following this thread with great interest.
So here in "police state" Ontario I would really question the economics of supercharging my car.
If you do it properly (supercharger kit, clutch, timing belt, intercooler, installation, shipping, taxes, etc, etc) I'll bet you don't get much change out of $20k all for about 0.6 of a second to 60 and bragging rights at your local show and shine :confused:

John
 
Yep, Ill take that bet too. I will even give you odds John!

And Im not talking about superchargers vs turbos; both set ups have excellent options available for OBDI cars in Ontario. As long as the power delivery is right for the car, an NSX with 50% or more power, everywhere in the range, is what it should have been IMO.

It feels right.
