Then tell me why the top form of racing in the world use DOHC.F1.
They have all of the money in the world and all of the people to find ways to make more power out of what they are given.
I still thing that DOHC is going to be better. In any form of racing.

 

First of all, DOHC Formula 1 cars barely make an 1/8th of the amount of power that pushrod top fuel cars do.

Also, Formula 1 cars are allowed to use 5 valves per cylinder, that would prevent them from using a single camshaft. Your B Series swap will NEVER have 5 valves per cylinder.

 

ryancivic2000........not bashing sohc at all, but they take a lot more money to make more power and it is the reason why there is only one truly powerful sohc out there that is very well known......Bisi (10sec all motor sohc)
(yes i know there is more than just one, i was speaking of the one most everyone will recognize)Now he is the man, but even he says it takes more money to get the type of power out of a sohc compared to a dohc.
how many daily driven 12 sec all motor sohc runnin around compared to dohc

 

You are absolutely wrong. Bisi NEVER said that it takes more money to make the SOHC fast. Bisi is on a MUCH MUCH tighter budget than his DOHC competitors. There are less parts in a SOHC engine, therefore less costs. I guarantee you, if you do a search on Honda-Tech for his posts, you will find that he says this. The reason Bisi is ahead of the game is his RESEARCH and because of his research, he chose the SOHC non-VTEC platform. He also doesn't have the expensive engine management the DOHC boys have, he's still using old school carbs and old school tuning techniques, MUCH cheaper.

 

if that is the case i must have miss read a post on h-t about this subject were bisi and omni both chimed in. i am not doubting you or dissing the sohc, but every where you read or look people are make the power easier and cheaper with a dohc.
how much does it cost to build a 200hp sohc, because you can do it on a dohc with oem parts.

 

I disagree. Everywhere you look everyone has swapped to a DOHC without researching or knowing the real potential of a SOHC motor. Everyone thinks that starting with the platform that has the most hp to begin with will result with the most hp in the end. This is not always true and is the reason why you only see a couple of SOHC big dogs out there.

Of course you can build a DOHC with 200hp and OEM parts because the damn HypeR is 200hp from factory. D and F series motors are EXTREMELY detuned from factory and therefore we don't have the caliber of intake manifolds, valvetrain components, etc available to us in OEM form for SOHCs. As far as REAL aftermarket parts though, they are much cheaper for SOHC than DOHC.

 

when i say 200hp i mean whp not crank hp............but to each his own. either way if i could have 200hp 1 cam or 2 id be happy

 

last autox i went to with the hatch i was able to get around a good 2/3 of the course in vtec in 2nd... *shrug*

 

i thank you all for the great info

 

Oh give me a damned break.
An F1 engine and a top fuel engine are two completely different beasts. One one hand you have a high output engine designed to last multiple laps and sport an exotic rev band and on the other hand you have a large motor designed to simply run down the track once or so and be torn down and rebuilt. Then there's specifics, F1 engines are limited to around 3.0l, they are NA, they are 10 cylinder (going to 8 next season I believe), the list goes on. The differences are far too great; I don't see how you even thought this would be a good comparison for your debate.
