NSX-T (2005) peak 336.3WHP/236TQ/7500 mi.

Several weeks ago, I was scheduled to bring my car into CT for a pre-install dyno. Then I was going to get the CT i/h/e installed at Acura, followed by a post-install dyno. The day before I was scheduled to bring my car into CT for the pre-install dyno, Shad called me and asked if I'd be willing to lend them my car for some development work.

The Whipple blowers (roots type) for the NSX SC kit are no longer available. So CT has been working on a replacement blower (Autorotor) for the last 6 months. They completed the 3.0L NSX SC kit with the new blower and were scheduled to use someone's car for the 3.2L NSX SC kit. But at the last minute, the 3.2L NSX wasn't available.

So Shad made me an offer I couldn't refuse. For letting them use my car to finalize the 3.2L kit, they would install the CT i/sc/h/e at a very very good price. Plus, they would do a dyno run for baseline, i/h/e and i/sc/h/e to see what each mod gained. I wasn't planning on the SC until next summer, but this was too good to pass up.

Stock
WHP: 247.4 @ 7200
TQ: 194 @ 5400

I/H/E
WHP: 266 @ 7500
TQ: 197 @ 6500

I/SC/H/E with ~5.9 PSI boost
WHP: 336.3 @ 7700
TQ: 236 @ 7000

A 88.9 WHP/42 TQ gain. Not too bad Next, the stage II kit (bigger injectors, smaller pulley and a black-box) that might make between 30-50 more WHP. Not available yet, but CT is considering it.

Additional Info
Both the Whipple and Autorotor blowers are 1.6L each. However, CT found that the Autorotor blower made 7 PSI boost using the original 6 PSI pulley. This is because the Autorotor blower design moves air more efficiently. The Whipple blower's end-casting had an opening at the top to pull air from, where as the Autorotor blower is less restrictive, pulling air through all of the end- casting. When my car was dyno'd, it was making close to 340 but running very lean at the upper RPM's. So CT did a test and put bigger injectors in. That made an additional 25WHP, but that made the mid-range RPM's too rich. They ended up going with a larger pulley to slow blower down which put boost back to 6 PSI. The Autorotor is also a lot quieter.

I'm very pleased with the results. Although these aren't earth-shaking numbers, car is sooooo much quicker and pull really hard in 1st-4th gear, as well as having a lot more grunt in 5th and 6th. The down side, the car's handling is no longer in par with it's power. Oh, and the sound of the i/sc/e is sooooo sweeeeet. I feel as though I've got a completely new car again. :tongue:


UPDATE: Temp was in the 80's, not sure of humidity.

While NSX is definately GORGEOUS , I'm not impressed with it's power and especially torque. Your own SC CL-S makes 30wtq more at the same given 6psi and delivers it 2000rpm earlier

Honda really should put a serious V8 in it, or our frankestein SC 3.5L AV6 really embarrass it by making 319whp/270wtq (TAG) on crappy AV6 OEM ECU (w/E-Manage) and our best buddy 02AV6 should dyno his new one soon

Otherwise, beautiful car!

My SC CL-S only run with 3.9 PSI. But #'s are only part of the equation, how it drives is the other part that really matters. And let me tell you, the car is amazingly fast. Keep in mind that the 3.2L NSX (stock) has been road tested with 0-60 of 4.5s and a 1/4 @ 12.9. With the SC in, I can hardly shift fast enough between 1st, 2nd and 3rd without hitting the rev limiter; engine spools up so much quicker. I wouldn't be surprise if 0-60 is 4.0 or less and 1/4 is low 12s or lower. With a stage II kit (in the making), could see another 50WHP/30 TQ.

It was deceptively fast before. But now, it's screams. I ran with an STI last night in some twisties and I can tell you that I pulled on him in the straights like he was standing still. But that's not a very good contest. I'd like to see how I could hang with various vettes. I'm sure some of the later models would own me; well at least until I get the stage II and a lower ratio ring/pinion.

I road in a CT fully prepared track 3.2L NSX that dyno'd at 435 WHP/380 TQ. I had never felt anything so fast before - completely insane. With every gear shift I was violently thrown back into the seat and remained pressed firmly against the it until the next gear shift.

I think 90 WHP/42 TQ is pretty good for boltons. When I'm done, should be more like 140 WHP/70 TQ. When you say "track", you mean dragstrip? I'm more interested in bringing it to a road course for a track day. But maybe I'll do the strip once just to say I did.

I guess what a bolton is is open for interpretation. Yeah, I was surprised there was only a 19 WHP/3 TQ for the i/h/e.

The X was just too quiet stock and I missed the whine from a SC.

CT designed a fuel/injector timing remapper box for the 04 TL. It does a lot better job than the ESM box used on the earlier SC kits. CT is thinking of using the same remapper box for the NSX stage II SC kits.

I don't know, just not impressed still with area under the curve. I'm sure stage II kit will wake it up for sure . Tractionwise however, seems NSX doing pretty good to hit those numbers. Enjoy!

S/C NSX

The S/C really beefed up the torque curve, which is much more important than peak HP numbers. Can't wait to see the track numbers for this car .

Well the NSXís 3.2L engine isn't that big, so gains from individual parts are not huge. And the stock parts you replaced weren't that restrictive to begin with .

Simply a stuning automobile. If I had that car I'd have a great big smile on a daily basis!

Most of the time I do have a big when driving it, especially now with the CTSC. Now that the handling is no longer on par with the power, next Feb. I hope to install CT springs/sways, konis and T1-Rs.

wow, very nice. i drove by a house recently with 3 yellow NSX's. i was shocked not because they could afford 3 (it was in a weathly area, million+ dollar community area, house also had a new S class in the long driveway), but 3?? i was thinking wow, that car must make people fall in love with it, they could have purchased 1 fully loaded ferrari f430 (modena, my dream car) or a nice lambo instead. says something about that car.

Nice looking car, I like the new SC kit Comptech has for the NSX, they make great stuff.

If you are looking at different Rims I would suggest the Work Meisters. I got a set of them for my Toyota and I havenít had any traction issues yet, and I have about 80+ more whp than you do. Very strong rim, Comptech uses them on their NSX, and S2000.

I had looked at the Work Meisters, but have settled on the Volk TE37s in silver.

The vids below were posted earlier on Acurazine. If you don't mind, I'll link to them from here.

Several weekends ago, I was up in Medford, OR for a car meet. On our way up to Crater Lake, we found a huge empty parking lot off the highway, in the middle of no where; a perfect place to shoot a video. About one- third of the way through the video you'll see a SC'd NSX do a fly-by.

West Coast Meet 4 Fly By's (right-mouse, Save Target As -- 57.3MB)

Download may take a while, but is well worth it.

Here's a run-off: SC'ed NSX vs. CTS-V with exhaust (right-mouse, Save Target As -- 19MB)

Yes and it's a SC'd 6MT CLS if you didn't already realize it.

It's not you dad's Cadillac. After seeing the CTS-V in person, I have a new found respect for Cadillac.

The Z's sounded really sweet too. I liked the sound my X exhaust, except on the last part of the highway run -- sounded kinda weird.
