Performance Upgrades

[AR]

I had Mugen headers and a Mugen ECU on the NSX-R. I did not like that the Mugen ECU Increased the rev limiter to? I could not, or should I say did not want to find out. As for the Headers, I doubt there is more than 5 hp difference from Taitec to Mugen, nice thing about them is the heathshields, BTW they are still available.

Here is a nice graph of the Taitec:

Isn't it that you loose your A/C with the MUGEN ECU?

Not at the version MUGEN developed for the 93 GT car.

5 HP as difference is a lot for headers only.
Its also a difference in torque, maybe you have seen that there are ~316 NM

BTW they are still available.

Where? You seems to know more than me

The 5 hp will more than likely be dyno related, I really doubt there is that much difference. They feel and sound the same to me.

As for where to buy them:

Bet you can't put an NSX-R sticker on them!

Mine came with that, yours not ?
You must have had a very old part than

I can say that there is a difference, even if you doubt.
MUGEN headers are by far the best, thats fact.

All your parts come with that LOL, have you calculate the Performance Downgrage from the extra weight of the stickers???

I am just joking with you I bought parts from you before, and your parts are expensive, but top notch!

The stickers are lighter than air.
My problem is that the most customers wanna have these stickers,
even the parts for the Honda race guys must have these.
Procar Specials = cf parts + Type R parts (specialist)

But there are still parts without that available.

Look here......

I would just add that on my 2005 3.2 liter, I gained 113 HP on the same dyno in the same conditions with the addition of a Comptech Supercharger and a GT-One F1 header and V5.0 exhaust system. According to Comptech the gain should be close to 75-80P. Somehow, I gained 35 or so horsepower OVER what this car should have had with a Comptech exhaust and Comptech headers. I don't know how, but I attribute a good amount of this to nothing except what I think is the best header available, including the Mugen or Fujitsubo.

A lot of times the term "equal length" is used, but all they are reffering to are equal length tubes on one bank of cylinders, and equal length on the second bank. The two banks actually are NOT equal, so the left 3 cylinders and the right 3 cylinders are actually seeing different length pipes. As far as I know, and I may be wrong on this, the GT-One F1 is the only header I have seen that has true equal length on all 6 tubes.

It was $3,000 for the header alone, but to me it was worth it for the incredible sound (I have heard this same exhaust with different headers and it does not sound the same) and the significant HP gains.

I think it is clear by now that if you have a 3.0 liter engine you will make large gains changing that horrible exhaust manifold. On a 3.2 your gains will be a lot smaller, in some cases none. The 3.2 factory manifold is excellent. I sold mine with 3000 miles on it for a mere $300, that's a fantastic deal to someone especially when you get OEM quality.

As far as intakes, a lot of people think that an open element intake sucks in a lot of hot air from the engine bay... this is true only at idle. When the car is moving at anything above 30MPH the engine bay temp in the NSX drops dramaticaly and is almost equal to ambient. There was a thread somehwhere on this from a guy on prime that actually ran tests on this.

I think Procar's approach to getting a larger airbox is a good one, generally the airbox itself is more restrictive than the element. I know that on my Mercedes CL600 the gain with a filter was nothing and the gain with the Renntech airbox was close to 40 HP. I talked to Hartmut Feyl (owner of Renntech and head of AMG for 19 years) about this and he said in general airboxes are the bottleneck not the filters.

Here is the F1 header for those not familiar:
