The TypeR has a redline of 8400-rpm. Our redline is 6900 rpm. Why is that?

 

How big is the type R's engine? 1.8L or something?

All type R's get there power from high rpms, ex-7800 rpms. I read this somwhere in motor trend. usualy all 4 bangers do. if u look at stock integs they red line at like 7500ish. I have never seen a V6 like our red lineing over 7000.

By the way web toker, i got my stuff installed today, it sounds so sweet. i can really feel a difernece in power off the line and at all sppeds,a nd that was w/ a full tank of gas. I get it dynoed tomm, cant wait.

 

Rhetorical #1: How much more reciprocating mass does your engine have over the Type R's?

Rhetorical #2: With how much diligence did Honda use to make sure your reciprocating masses are absolutely balanced?

Rhetorical #3: How much higher spring rates would the higher valvetrain masses of your SOHC engine require to prevent float at 8400rpm?

Sweet, I only wish my wife would let me purchase the headers. She is right though, a house is more important at this point. But after that its fair game ;-)

Its more like she reminds me. I can go out and buy headers but when we miss the next years tax write off because I didn't save up enough money to close on a house before Oct., who do you think she is gonna look at?

just makes you appreciate more the E46 M3 engine! and also understand the rumors about the crankshaft not lasting over 30,000 miles... hence the long delay. the curious thing about that engine is that it really doesn't make that much more considering all the technology they loaded into it (versus the Euro spec E36 M3). unless they understated things.

 

better 'just do it' so you can get on with buying more 'car toys'!!!! lemme know if you need any help on anything--ya got a friend who just happens to be an architect

 

times like this i wish i knew more about cars so i knew why 1 redline is different from another redline.

Type R has DOHC VTEC engine which is high output horsepower engine...and our SOHC VTEC engine is made to fuel efficiency....although it is pretty powerful...but 6900 RPM redline is pretty cool already

im tellin you if we can find someone to reprogramm our ecu look close at the comptech dyno and know this if we got redline raised 1500 more which isnt un do-able look how much more time we'll spend above 175 hp

My Maxima had a 6000 redline, which was great for that car. At 80 I was running about 3000 on the tach. At 80 in the CLS it's about 2200, big difference. The more power, the less hard the engine has to run. Consistently running high RPM's gotta be rough.... 193 in the V6 Max vs 2600 in the V6 Acura.

I asked a buddy longtime ago about the same thing. And he said 4cylinders can tach more because there are less parts in the engine moving at the high rpm.

But, i think is the size of the stroke. The smaller the engine, the shorter the stroke...higher rpm's.

Anyway, my 2cents.

 

Ya gotta remember that Honda was a motorcycle manufacturer who placed more importance on motorcycle engines than cars when they came to the US. Their motorcycle engines are up to 1.0 liter I think or higher in the case of the GoldWing (flat 6) and then have been known for creating over 110HP from a 1.0 liter engine with a rev range of 13,000RPM and higher with a 4 cylinder. I know cuz I rode one. If you don't think 13,000RPM's is high then there's nothing else more exciting you could between your legs.

I always thought it was because 4's need the extra rpms to achieve the proper amount of torque. With a larger displacement, required torque can be achieved at lower rpms. I think the "less moving parts" argument applies to rotary engines moreso than 4's.

I agree we should have a higher redline. I am tired of the fuel cutting off just when it starts getting fun. I think the redline is very limited on the CL-S because of the domed pistons we have. There would be a high risk of sending a valve into the piston if the redline were higher. The dome pistons give us the 10.5 to 1 compression ratio. I guess it's a trade off.

i hit fuel cut too much i think its cause from my ear i feel the engine has more to give but the computer denies me whats the redline on the NSX??? ill bet higher

Trade off.

What good is a higher rpm if you're not making any more power??? If our peak power is still 260 and it come at 7500 rpms instead of 6100 rpms... then you'll just wind up with less midrange power. When you drive a 3500 pound midsize car, you want that midrange power. Putting the s2000 engine in the CL would suck ass.

 

the peak powers not gonna change were just gonna go deeper into the rpm band and power does start to fall but not like when you r car shifts and on top of it when you card does shift youll be in a higher rpm hence lots more power and BTW the nsx3.2 has a reline of 8000 so i see no reason why we couldnt do the same thing with a little valve and lifter work

I've got a hard drive that spins 10K, does that count?

The one thing thats funny, when I got the new drive a while ago, I was hella surprised that it has an INTAKE vent for air flow!! but it does make sense.
in one word: *sweeet*

One question:
Is there a correlation between high/low RPMs, torque, and fuel consumption? E.g. Audis are known to be torque monsters..and from what I can guess they consume lotsa fuel

Is this something to do with low range power and/or high range power?

Well, the I6 design's got the longest crankshaft for any given dispacement (except for the archaic I8), so I'm not surprised that they'd run into initial reliability problems if they went for the NA low-loss-of-efficiency-at-high-RPM route.

On the other hand, it is easier to get power via that route from an I6 as opposed to a V6 (even a DOHC one), since there would be the inherent V6 imbalance in moments and forces that would need to be quelled with a balance shaft (parasitic drag) in order to keep the engine from shaking itself apart. There's also the two sets of valvetrains that are going to be more massive (inertia) and need more bearings (parasitic drag) to support. I suppose that's why even with Honda's fanaticism, the NSX got "only" (relative to the E46 M3, of course) 290hp out of 3.2 litres.

There new engine probably features more useable torque all around, which should come in handy in pepping up the heavier E46.

That's a gearing issue not an rpm issue. But, I do agree... 8100 rpm in a type-R brings a big smile to my face.

youre not hearing me...our car exactally the way it is if you shift at 6900 then the car in the next gear drops rpms down to im guessing 3500 this is at wot if the shift came at 8000 then the car would drop to 4600 next gear see where im going more power at 4600 then 3500 however torque does seem to drop off dramatically at the higher rpm but the higher inertia might counter that
