I was looking at the readers rides and some guy said he had a 4 banger honda Vtec in his Camaro. Does anyone know about this, I kinda think it's stupid...but interesting.

 

I think it would make an interesting contrast and comparison between the two "breeds" of cars when trying to determine the "better" choice. We already know what a SBC will do in a Honda... What would a Camaro do with one of those sewing machine motors.

Better yet, how did he get one to work in a RWD setup?

You have to remember there's people who come here with the only intention to start crap (trolling). This may (or may not) be the case here.

Either way, even a good photohack job would be kind of entertaining to glance at. But I'm always interested in strange works in mechanical engineering. I worked for a guy who turned a fuel injected Toyota Celica GT motor into a carbureted motor in his hotrod with a Chevy V6 distributor and accessories, Corvair carbs, and fabricated intake manifold. People always wonder "why", but I just wonder "how".. Knowing "why" doesn't make me any smarter.

 

i doubt this is true. I had a car w/ a vtec engine and it is many times different then the sbc. For starters, the motor mounts are around the perifery of the motor off to the sides of the engine bay. It would be a real pita to do it. And the second issue is that a N/A vtec would never have enough low end torque to move a heavy camaro. It barly had enough torque to move the little car that it was in. Interesting engine design, though, but its rapidly being outdated by the newer fully variable valve timing systems.

 

v-tec, well i suppose it was interesting school engineering project that probably got someone an A.....and maybe it would work awesome on a big v8, however...

im gonna have to quote a car craft article here entitled, why imports suck....us: old tech push rod v8 making 500 hp...them: state of the art fully electronic variable valve timing motor making 170 hp. nuff said:rockon:

 

I saw that one.. :sillylol:

 

well, i can tell you what is probably going to be the future of v-8 performance.....

Ford is currently developing a motor that will see production for pickup trucks. It a camless diesel, where the valves are all computer controlled and actuated by solenoids. This is a great idea because it allows for infinitely variable valve timing and duration.

Also, the perfect ideal graph of valve movement would be square not curved....for example the valve would be instantaneously all the way open at the ideal time, remain totally open for the ideal duration, and then instanteously shut.

this is physically impossible to do, but with this technology you can get daaaamn close. the computer software that controls it wouldnt be much different from what controls a sequential injection system really. with a few more variables. the computer could continously adjust for ideal valve motion at every operating RPM....this could translate into amazing increases in power output, my guess would be close to double if not better. :rockon:it wont be long before this finds its way into the mainstream gas motor market.....problem is if a solenoid bites the big one.....your motor is history

 

That's scary since the last motor that had valve controlled soleniods bit the big one...(V8-6-4 / Cadillac / 1981)

 

that engine never saw production for obvious reasons.....

in 1981 there simply wasnt the technology to operate a system like that.....also, the arent really solenoids so to speak, there really actuators...some designs are hydraulic in nature while others are electrically operated......the design is currently being tested and is soon to see production by navistar.....the company that makes the diesels they put in ford trucks and internationals. 70% reduction in emissions, 20% better mileage with way more power and torque.

and thats in a diesel!

 

No Caddy's had them in 81. Most were recalled because of solenoid failure. But there are still a few out there.....

 

solenoids and computer control...that is gonna be one hell of a disaster should anything go wrong. seems stupid, especially for ford since they have trouble with their smaller engines as it is...
Why replace a camshaft when it obviously does its job so well. And it is impossibe for a valve to open instantaneously and shut instantaneously. you can cut it really close, but it will always be a curve...

 

I think its a good probability, but its strange that the first company to go into production with a system like that is Ford, for a truck engine?

Its really high tech, and to my understanding (Or if I remember) those systems have not even got into high performance engines where they usually try thing first, like in a porsche, ferrary, lamborghini, even Honda or Toyota.

 

i repeat this engine WILL be produced. Navistar developed the technology for diesels in order to meet stringent regulations that are coming up for truck engines emissions. navistar is the company that makes the diesel engines for Ford and international.
The reason you want to do this, is because a camshaft although proven and well used, is a limited technology, and in order to advance to the next step you have to do something different. The actuator technology has advanced quite a bit too. also, by building this type of engine, they diesel design eliminated 170 some odd moving parts from the engine. This also greatly reduced production costs. it eliminates the need for a seperate jake brake on a large diesel too. once again, the huge power production potential is here too. I looked into this cadillac nonsense and as i suspected, i didnt find any information on it so if anyone knows where it is id like to see it

 

Its not the same thing. The new setups have valves controlled by the solenoid. There is no camshaft, no rocker arm, no pushrod, none of that stuff. The Cadillac setup was entirely different, and the lobe profile was limited by the shape of the camshaft, a physical part. The solenoid actuated valves have a lobe profile limited only by the programming and things like valve weight and speed. Still cant move them too fast or things will start breaking. They are also not rigged up to totally shut off cylinders or have them at 100% operation (which is what the Caddy setup did) but rather varies the duration and lift based upon engine speed and load.

 

I understand how beneficial this could be, anyone know where I can read more info about this?

I found a very interisting link about new technical (and not so new) advancements on cars

http://autozine.kyul.net/technical_s...tech_index.htm

Also I found this link (while searching about different ways to actuate the valeves) about a suposed valve mechanism that would allow the use of very loppy cams without degrading torque at low rpm (It some kind of continuosly variable valve timing) and it works replacing just the valve not the cam.

Im relly interested in any link about this.

 

a v-tech 4banger degrading a sacred f-bod?????? there is a very appropriate four letter word for that.....

****!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

hey why wont it let me say r*ce in my last post?? is it suddenly wrong for me the owner of a respectable and powerful v8 street machine to degrade the stupid asian kids in their honda civics?????? **********!!!!!!!!! ****!!!! ****!!!! ****!!!!

 

o great

 

You got that right.
