Yea, r/s ratio is somewhere around 1.86. Very favorable on your walls.

I said, "worry about making power first and how high you have to rev later." It doesn't matter where you make your power as long as you're making it. I see people all over this site saying "how high can rev?" without even taking into consideration where their power is going to be made at. If you can make the same power at 7000rpm, why worry about revving to 10000rpm? It's just going to put added stress on the motor.

I'm very aware that these are high strung motors to begin with, but it's also a fairly well known fact that any motor will break if you beat on it enough. Free revving eh? Rev a B16 to 12k and tell me how that works for it. My guess is that RPMs will ruin the motor...what do you think? Take a b16 to 9k on a daily basis and guess what, you'll end up with a ruined motor. It might annoy you, but it's still very true. Don't forget that race motors are torn down on a very regular basis.</TD></TR></TABLE>

Go play in another sand box. No body is talking about revving to the moon. He just asked whether the B16b could rev higher. No one in this thread has even said anything about 10k+ rpms. You come out with your RPM = ruins peoples motors crap which means you obviously shift at the recommended shifts from Honda, right? I mean, why go any higher because all you are doing is ruining your motor faster, right?

A stock bottom end B16b or B18c5 can and will rev to 9k safely with the apporpriate valve train. Heck, I know people taking it to 8600 safely on stock block and head without any adverse affects. That includes drag and road course.

Being that "race" motor is a pretty subjective term, I guess you're going to tell me that everybody who races honda-challenge tears their motor apart after every race, right? Now you are talking about high compression (OE) bottoms ends with built heads pushing 9k+ RPMs for extended lengths of time for an entire season with no rebuilds. Stop with your nonsense. Go play in another thread unless you'd like to provide some pros and cons on the motor inquired by the OP.

 

I ended up getting a 2000 model year CTR for $1000, so there are deals out there. If you really want good power and out put, you can always yank the rotating assembly in favor of ones from a B18 to stroke it back out. Torque truely is a nice thing.



Btw, the CTR block is a P72. The same one used for the B18C1 (gsr), and the B18C5 (itr).

 

Isnt a B16B just a basically a destroked ITR motor more than it is a B16A?

Yes.

Exactly correct

Oh good fuccing grief. Talk about taking a running leap off the deep end. This drivle is barely worth replying to.

Perhaps you should learn how to understand what you read before you go firing off on t3h intArnet. Again, I said, and I'll make it really hard to miss this time, <u>WORRY ABOUT MAKING POWER FIRST AND THEN WORRY ABOUT REV'ING HIGH</u>. There, hopefully that was plain enough.

Do I shift at the recommended shift points? No, I don't have a stock motor. However, I wasn't thinking "geez, I wonder how high I can rev this thing?!?" when I was building it. I was thinking, "I wonder how I can make the most power across the board?"

Show me where I said you can't rev these motors? Again, I said do it on a stock motor on a daily basis and you will eventually ruin the motor. It's a fact. Sorry.

When did I say that race motors get torn down after every race? Jump to conclusions much? I have a friend who builds motors for NASCAR, I used to be in a band with him. His motors tend to last an entire season, but the motors get a rebuild at least once a season. That's what, maybe 15k miles before a rebuild? Now, I would call that a fairly regular basis.

My entire comment about rev'ing was based on this comment, "ok but i can get higher revs with a b16b right? can that accelerate harder than a b18?" At that point, worry about making power first. How high you need to rev will depend on your setup, don't pick a setup based on how high you want to rev. If you can make the same power at 7k that you can make at 10k, why rev all the way up? Being able to rev higher won't make a car accelerate any faster, it just means the car has to rev a lot higher to make power. Why worry about how high it will rev? Just make power. That was my comment. Don't pick a motor because it's high strung. Pick it because it will deliver what you want out of the finished package.

Now why don't you take your own advice and run along to your sandbox. Shoo. The big folks are trying to talk.

Just think about the situation before you answer a question.

The OP obviously knows very little about each motor and has a few simple questions which need a few simple answers.

Can a B16b rev higher then a B18c. Theoretically yes. But no it will not pull any harder than a 1.8....stock. End of answer.

Stock for stock, a B18c usually peaks in power at about 8000 rpm, a B16b will peak in power at around 8150-8200 rpm. Although the peak hp for a B16b is obviously smaller. So YES! a B16b needs to rev longer to makes it power. A B18c is STILL making more power than a B16b at 8200, but is has peaked and is dropping in power.

An added bonus in keeping in the revs means you don't have to shift coming into a turn, or one less **** on the drag strip, OR when you shift the RPM's will keep you in VTEC.

"Ruins peoples motors" is stock v8 garbage, which now makes more sense coming from you since you have buddies building NASCAR engines. Which motor will last longer: B16 running at 3k rpm for all its life or a B16 running at 5k all its life? I'd hedge my bets on the one running at 3k rpm. But seriously, it will take forever for either one to grenade. 8k is not even remotely terminal on these motors. 9k is probably just beyond safe with valve float being the limiting factor.
