what are the benefits of a dohc over a sohc?

 

jeebias.....

 

you have got to be kidding me

 

extra piston return tensile spring strength, longer closed exhaust outlet path diameter, simple stuff like that.

 

yeah im pretty ignorant about this sort of thing. I have looked all over the net for a dohc for my 96 accord and have not found anything.

 

hmmmmmmm............maybe an h22 or a h23 for god sakes!!!!!

 

this is another stupid question... ( i have tons of them) is the setup in the accord the same as the prelude?

 

oh my god......since misas head exploded after reading this, can i be the new mod. RIP Misa.......anurysims are a bitch....


No the setup if different.

 

heres the deal i want to make my 96 accord haul ***. i am not very smart on these matters as i see you obviously are. lets say i was going to spend $7,000 on this project. what would you suggest?

 

H22A Nitroused. Run a search dude, you will find a plethora of good stuff.

 

hey go_noles28...don't worry about these guys...they are just upset after answering the same questions over and over...but here's a start...the dohc head and sohc head are two very different things...the single overhead cam is less powerful because it is using one cam to control both the intake and exhaust at the same time...but the dohc head uses two individual ones hence more power...but there are a whole lot more factors affecting power as well but the list is so long and it's so late that i'm not even gonna try and list it right now ...and the prelude and accord setup are different yes...but i believe the f23a was an option for the 92-95 preludes which is somewhat like the accord engine...but the preludes mainly use h series motors which are dohc...the h23 is non-vtec...many people with this engine use a turbo because of the lack of vtec...and the h22 is a vtec motor and some people use a turbo on it but they mainly just go all motor instead of boost...hope that gives you a start!

 

i have done the cold air intake, header and catback already, but i did not get any noticeable results out of that.

 

they don't make DOHC Accord engines...
the only one that's in DOHC is the Accord Si R ^_^

holy shiat...you have 7 grand to spend on your accord...geez...well you should get a prelude engine and boost boost boost...and maybe some nitrous as well...that'd make your car 'haul ***'....

 

thanks for the info... you were much help this was my first time on here

 

give me all of your money, and i will show you a fast accord. wont be yours though. hehe

 

dude i paid for my car 13k in cash, and spent 6k on it so far...and it's still slow...fck

lol =P i should have waited and just buy a s2k

 

H22 + boost

its really that easy

 

19k on your accord? goo loawd...

 

For 5000 dollars you can buy the accord in this post: https://honda-tech.com/zerothread?id=186188 and then sell your accord and use the money to put a turbo on it. You will be one quick ****

 

dohc valvetrains are intrinsically lighter than sohc designs, motor more balanced, higher revs are possable, cams can be adjusted independantly of eachother to add/remove valve overlap...

i should have moved this thread to the newbies corner

 

I dont see how this is possible. SOHC engines only have 1 Camshaft while DOHC engines have 2. When I did a research paper about Cams for an engineering clas I took a while back I had in my possession cams from an H22A and cams from a D16Y8. The 1 camshaft from the D16 was about 1/2the weight of the H22 camshafts. Add in the weight of the cam gears from the H22 and I do not see how the DOHC could get lighter. Both engines do have the same number of valves and stuff so I dont see how the rest of the valvtrain on the DOHC engine could make up for the weight of the 2 Camshafts to make it lighter. Yes I know these are different sized motors but still it really doesnt add up.

 

because each cam is operating 8 valves at one time and not 16......
more tuneability etc....

but then just ask yourself, why dont all race teams use sohc motors then.....?(im notalking about nascrap)

 

Has anyone actually weighed the difference between the F22B1 and the H22?

 

I am not talking about tuning just weight here. I know DOHC has more tunability but as far as weight DOHC has more of it expecially when talking about rotational weight. Sure on a SOHC engine the single camshaft is moving 16 valves but in a dohc engine the 2 camshafts are moving 16 valves as well.
