New Clutch + Short Gears + R&P = Sa-weet!!!

Well, my clutch was starting to give out, so I decided to have Mark Basch and Mark Johnson replace it with the Dali Streetracer Clutch. Well, since Mark B. was already working on it, he suggested I also have the Short Gears and 4.55 Ring & Pinion installed, since I could save on labor. Hmm, well, I was planning on getting that anyways, so I went ahead and had them do that along with the clutch.

Got the car back this weekend, and just now starting to open her up. F*CK!!! This sh*t is dope!!! I love it!! The car responds so much better. Shifts are so much tighter. Big time AWESOME!!! It's like being addicted to some sort of Speed Crack!!! I can't help myself.

The car does run a little louder at freeway cruising, but I wouldn't say it screams, at least not any more than before. At around "freeway speed limit speeds", the car cruises in the high 3000RPMs. Even with my RM Exhaust, I still don't find it annoying. If anything, the sound to me is quite entoxicating. (It doesn't hurt that I also used to cruise around in my screamin' Integra GS-R with a cat-back exhaust. I guess I'm just used to it.) I'd have to see if it gets too loud on some trip to Los Angeles or perhaps Vegas. Regardless, the car doesn't seem to make much more noise than before.

Bottom line, if you can afford it, you gotta do it!!!

Thanks a bunch to Mark B. and Mark J.!!!

Nice! You need to give me a ride during the next meet. I plan to do this too and would like to experience the difference.
How much did everything run you?
 
Well the lull in 2nd gear is really starting to bug so I'm thrilled to hear the difference is worth it. After reading the active thread on the 6-speed conversion not being worth it financially I am now revisiting the idea of going your route. How much, if you don't mind asking? Feel free to private email me.

Thanks,

Alan

I would like to get the 4.55 R&P by itself because it seems like the overall acceleration numbers are best (0 - 150mph) for the buck.

Does anyone have this setup? Fury NSX, any slow down in 100+ acceleration?
 
My short gears, Dali clutch and light weight flywheel don't seem to be that different..... i can tell that the gears are "closer" but acceleration seems to be only a little bit better...

as far as the revs being easier to rise and drop... that all about the same..

am i losing my mind??

Changing the gearing does not tend to create dramatic differences in acceleration. Check out the "What are the Numbers" chart in the FAQ section on "Gears" and you'll see that you get a lot more benefit from adding 20 hp than you do from changing gearing.

I think this is because, when you change the gearing, you reach redline sooner - so it gives the perception of being quicker - but you do so at a lower road speed. Actual differences in acceleration tend to be less than they seem. Remember, as you move through the gears, you're changing gears, changing gears, changing gears. If your gears (or R&P) are shorter, but it forces you into a higher gear at a given road speed, any advantage you may have had may be offset by the upshift.
 
Electro,

I'm not surprised that you're not seeing much of a difference in acceleration with the short gears, clutch and flywheel.

Short gears don't really change the final drive ratio, they just make the changes between gears more even.

However, I do think that changing the R&P will affect actual acceleration and that depending on the ratio you choose the difference could be very noticeable.

Try starting out in 2nd gear to see how acceleration is impacted by the final drive ratio.

Much of what you say is true of course, but I think you still underestimate the effect during daily driving. The lower R&P gives you better torque multiplying throughout the rev range in all gears, and the gear set adds to that in gears 2-4, giving it back only in 5th. By contrast, short of nitrous/turbo/SC, an honest gain of 20 peak HP is tough to get after you've done headers & exhaust, and is actually far less than that in the rev ranges you drive most of the time. What I'm saying is tha the impact on daily driving is not the same thing as raw 0-60 or 1/4 mile ETs.

I wish more people would buy a G-Cube or similar device and record acceleration before and after such changes. For anyone near St. Louis, I'd be glad to supply one.

Little off the subject, but I am laughing that I am reading this today of all days. I did not even know what this thing called a g-cube was until last week when a buddy called and said he got one. We are going to go out and play in our cars today. Are these things accurate?

I got a G-Tech Pro just last week. Unfortunately, I got it the same day I got my car back, so I was unable to record a before and after. My understanding after reading an article and a few posts from users is that it's pretty accurate, given the fact that nothing is actually attached permanently to your car, and the fact that it's only $140.

You can see exactly the impact of changing the gearing by looking at the charts under the heading, "What Are the Numbers?", here. In general, they do help acceleration, but the differences are quite small.

The G-Tech Pro is good fun for low $, but it doesn't in any way compare to the G-Cube which records both acceleration/braking and lateral Gs continuously to then be used with PC software. You can see how the car pulls anywhere in the rev range in any gear, and that's just the tip of the iceberg.
 
I'm new with NSX and I don't understand what the R&P do for a gear box ?? I know that short gears will keep the engine in higher RPM's

but then why you would need R&P ??

Can you do short Gears and NO R&P ? or the other way around ?

Thanks,

They shorten the gearing.

The purpose of the R&P is to shorten the gearing in ALL the gears.

The purpose of the short gears for the NSX is to change the SPACING of the gears, not to shorten ALL of them. The stock U.S. five-speed has a relatively large gap between first gear and second gear. The short gears replace gears 2 through 4 so that the spacing from first to second is closer than stock, while slightly widening the spacing from second to fifth.

Can you do short Gears and NO R&P ?

Yes.

or the other way around ?

Yes.

Numbers on a graph are nice to have, but when I drove my car after I did short gears and r&p I noticed a huge difference in 0-100 acceleratiion and in pulling power. I then added intake, headers and exhaust and my car now gets sideways in second and spins in third. it never did that stock.

You have discovered the difference between perceived improvement and actual (measurable) improvement.
 
Where is the cheapest place to get R&P and short gears ?

I found on RMnsx.com website
$799 for short gears
$899 for R&P
Are those good prices or there are cheaper places to get those.

Thanks,

I don't know the answer to this question. However...

If I still lived in New Jersey, I would want to have the gears installed by someone who knows what they're doing. The most experienced NSX mechanic in the Northeast is Bernie Blatnick, who works at Davis Acura in Langhorne PA (northeast of Philly), so that's where I would be taking it. AND... (in case you're wondering how this ties in to your question) ...I know that Davis Acura has a policy of not installing parts purchased elsewhere.

In other words, if I had my NSX in Jersey, I would be talking with Davis about doing the install there, and that means buying the parts there, too. Just something to consider.

If you're burning rubber in third (which I truly doubt) then you are badly abusing the car. Even doing it in second is wasted abuse for no gain.

And I thought I whipped them hard!

I didn't say I was burning rubber, just spinning in third. not bad, but enough to hear the tires squeal. I do it for personal enjoyment and because I can. If you want to drive with grandpa on Sunday thats your choice, but I like to take mine to the edge.
DRIVE IT LIKE YOU STOLE IT. YOU ONLY LIVE ONCE.

If there is one thing I don't do, it's drive like grandpa! But I certainly don't consider popping the clutch out at WOT in third to get a little chirp to be taking it "to the edge". If you enjoy it, fine, but it hardly rates as heroic.

As for David's comments, I doubt that laying down the rubber in second requires any extraordinary abuse with his monster. Love that car!

If you ever visit the casinos of the Gulf coast let me know and I'll show you where the edge is. I dont claim to be heroic, but I do know how to get the most out of my car, or motorcycle(CBR 900RR) or Jeep(40 inch tires,440 HP Vette motor) or truck(chevy 350). and I dont do it by popping the clutch at WOT in third, that is abuse.
