So.. from eveything I hear.. the b20 is the block to have and the b18c5 is the head to have.. hmmm...
imagine.. A honda built super car with a V8. A bottom end that is built as well as b18c5 bottom ends or ctr's and use 2 b18c5 heads for the heads.. make the engine about say.. hmmm 3.5-4.5 liters slap on some dual titanium valvesprings and the whatnots and give it a redline in the neighborhood of 9000rpm..

Wow! Imagine the possiblities! A V8 at 9000 rpm's must sound pretty wicked. If honda could do 120hp/liter in the s2000 then what about a 3.5 or 4 liter engine? v6 v8? What if honda adapted a 5valve/cylinder head?

Well.. can you tell I like to dream big.. after all this is the place for tech theory!

thats alot of RPM's for a V8 dont know how well that will hold up

 

ever see honda's racing program??? i-4's, v6's, v8's and v10's and boost!!

 

You said it right there... "RACING PROGRAM"

Whats the nsx's v6 redline?
That might give some insight into a max rpm for a v-8

Just because it's a v8 doesn't mean that it won't rev high. Think about the F1 engines. Those are what? V12s I want to say, but they may be smaller. The trick is that they're low displacement, like 3.5 liter range. And those things rev into the teens. I've heard terms like 17000 rpm red line get kicked around. Of course, the manufacturers won't say what the actual redline is.

Well. The Ferrari F399 (F1 car) is a 3 liter v10 that rapps out at 19k rpm.. I think that an interview with Micheal Shumacher he said that the Ferrari engine has only seen 19k rpm once or twice in testing or qualifying. But for the most part.. F1 cars are v10's and v12's that are 3 liters naturally aspirated that produce 810 HP.

Now remember these engines develop NO POWER under 7k rpm.. infact, if you revved to 6k and dropped the clutch it wouldn't move the car These cars have a very different power curve than what we're used to seeing. These engines don't even use valve springs for god's sake.. they use hydrolic valves.

Our "normal" engines on a dyno graph round out at high rpms, infact some motors lose power the higher they go, as we all know.. The F1's are the complete opposite. Their power curve looks almost opposite of what a normal engines curve looks like.. their curve illustrates an infinite potential of power up the rpm side of the dyno chart that is why they push for such high rpms.. that is why they have 3 liters and 810+ hp!

But I'm not talking about F1's with this honda monster.. I'm talking about street legal super car that weighs or looks something like an nsx with a 500+hp 9krpm v8!
Just my imagination!

 

Its not hydraulic...its pneumatic springs. I think they use a gas like nitrogen or something like that. V12's aren't legal in F1 anymore. Stupid rules.

Ferrari has a 5 valve per cyl V8 3.6 liter engine in the Modena road car producing 395-400HP@8500RPM. The technology is there but is Honda willing to produce such a road engine at a reasonable cost?

hydrolic valves.. ha what was I thinking.. my bad..

Well, from what I hear the NSX ain't cheap.. true, it is far cheaper than a ferrari but hey, what the hell! That's right about the v12's I haven't been able to watch F1 for quite some time. Ferrari went from a V12 to a V10 the year after Shumy won his championship with them but I don't think F1 dissallowed the v12 at that point.. I think the "outlawing" of v12's was later? correct me if I'm wrong.

Anyway. I think honda could make a street "sellable" v8 or v10 monster without going over 150k. Or they could just fit the NSX block with some Fantastic 5valve/cyl heads, a supercharger and 9000rpms..

once again.. I like to dream big!

 

i personally have wondered about the same thing.. a quad-cam, variably timed, 5valve per cylinder, high displacing monster with 100hp+ per liter that revs to 9k!! then think about a twin turbo version... yummy...

 

here's another thought? has honda ever considered producing a rotary engine?

 

The reason Ferrari's sound like two four cylinder engines is because they use a flat crank. A standard V-8 like say Toyota, Ford Chevy do not. Thats why Ferrari's sound so insane. If you wanted a Honda 8 cyl. to sound like two B18C5's Honda would need to use a flat crank design.

i think one of the reason why NSX are so expensive is because it's all aluminum.

 

the new 2004 NSX is getting a vtec V8 isn't it. The current NSX redlines at 8000 rpm, so I don't think we should expect anything less from the next one. I think it's fair to expect at least 350 hp from a vtec V8.

And actually, maybe somebody knows this, but I'll bet honda has some sort of new valve timing/lift plan up their sleeve. Hopefully something similar to BMW's new system, I can't remember what it's called, but there's not throttle body. Air flow is controlled by varying the valve lift and duration continuously.

My dad likes Mustangs, so he gets a few stang mags. Quite a few Mustangs rev up to 8k. My dad's 65 stang does 8k RPM, Im pretty sure.

I've seen some twin/single turbo stangs run up to 10k RPM. They make like 2000 HP or something. Plus they have torque.

But a Honda V8...mmmmmmmm THE ULTIMATE SWAP!!!
"Yeah just slap that FWD Honda V8 in my Civic, it'll fit, its a B series!"

 

There is nothing inherent about the V8 design that prevents high revs. The reason V8s have a reputation for not being able to rev is the primitive pushrod valvetrain used by domestic V8s. But if you slap on modern, DOHC heads, things would change considerably. Unfortunately, few manufacturers actually seem interested in building high displacement, DOHC, 32 valve V8s. One exception that a friend told me about is a 900 cubic inch, DOHC, 32 valve marine V8 that produces 1200HP on 87 octane fuel. This comes out to around 80HP/liter. About the same as a B18B.

 

damn! Slap one of those in a suburban or tahoe!! Thats HUGE!!!!!!!!

 

"just slap in that honda v8 in my civic.. it will fit.. it's a b series" lol oh my god that's the funniest damn thing I've ever read!!

Yea and does hasport make a mount kit?

 

yeah they are working closely with Honda to make sure the kit is just right. Prototype Engine = Prototype Engine Mounts

 

Honda CART engine = 2.6L V8, twin turbo, 800HP @15,000rpm

 

Yea, but can you get 150,000 streetable miles out of it? plus gasoline? gas mileage??

That's what I'm sayin'
