F7P Head vs F7R Head

[exechapur]

Hy pals, how are you?


I have a question, wich of this two heads completes (with cams and everything) makes the engine faster?


Do you understand what i mean?


I ever thought that F7R head was better, but i've readed here another thing, what do you think?


Thanks and best regards!!!

Thanks pal for your help!!!

What do you think about cams, which are better? :roll:

Depends which F7R you are talking about. The williams or the megane. The williams F7R has bigger valves and I believe the inlet and outlet ports are larger in size, the megane on the otherhand, not sure on the valves, but they have smaller ports which make a lot of difference mid range on torque, however its distributless.

f7r williams cams are more aggressive than the f7r megane cams, 1.8 f7p cams are again more aggressive than the meggy cams, so ideally you want the williams head with cams

Thanks for everyone for helping me...

What are the meggy cams?

I didn't understand that...


There are something else that i don't understand:

If clio williams has more aggresive cams and more aggresive head than megane,
why both of them has 150hp? :?::?:

Thanks you again!!!

Megane head as the biggest valves.

Thanks you again!!!

its the profile of the cams, the meggy ones are abit milder than the f7p ones and again the willie ones are a tad wilder than the 2 ive said about

 

[exechapur]

Thanks you guys!!!

So, the ideal preparation would be:

williams cams and megane head?

or

williams cams and williams head?


Thanks!!!

it would be easier if you use the willie head and cams as the megane head needs to be machined to take the distributor (meggy engines use coil packs)

the megane head is a superior design, the 1.8 and Clio Williams heads have inlet ports that are way too big.

Thats why the megane has the same power output and a wider torque band than the Clio Williams.

Ok, thanks you guys...

Now let me make another question...

I'll use the F7P head, how can i modificate it to make my car faster?

You are so friendly with newbies... :roll::roll::roll:

 

[jay]

i wouldnt port it tbh as chris said, the inlet ports are to big anyway, stick a set of cams in the head and do a full rebuild on the head ie stem seals, good clean and cut the valves in again, job done

I don't think he was being un-friendly, think he was trying to say that if you use a seach engine, you may find an in-depth explanation showing all the tech measurements

Yes, i've used it, but it's in english and is hard to understand technical english... :|
