Should i get more hp with flattop psitons?

From what i understand is that the flattop pistons give 9 to1 compression
While the stock roller forged pistons get 8 to 1

stock roller motor out of a mustang is 225 hp with dish pistons

Should i get more hp with the flattop pistons?

(yes you should)

Please no stupid comments. If you got nothing nice to say, dont say it at all. Just looking for some real answers (may be stupid but i'm asking it). Also things are slow here.
More compression = more hp, right? right.:16suspect

btw, How come i always mess up on the title?

These are the roller pistons but mine do not have the valve reliefs

 

I've been told some amount of h.p. but do some more research.

 

you are correct on more comp. = more HP ! ALL things have to work together, not sure if pistons need valve cut or not. Even if math says you have clearance,,, always best to roll engine over and check.

not sure on what you mean on roller pistons,,, roller engine or float wrist pin?

 

It depends on the Chamber size on the heads, you cant just say it will give so and so ratio with out knowing the chamber size.

That's why piston makers give you a compression ratio chart with the average chamber sizes.

then you also have to factor in gasket thickness and so on...

Because you type too fast!
are you running firefox? it has spell check!

 

roller motor pistons shown below first post:Handshake

 

I think i need to update my acrobate reader, it wont allow spell check:16suspect

 

No it is not.

Depends.

Ok....you're not stupid. Just misinformed. Is that better?

Funny.....those sure as hell LOOK like valve reliefs to me. See those little notches in the face of the piston? Those are valve reliefs.

 

In my terms of describing the pistons, i ment that those are the STYLE pistons without the valve reliefs (i just did it again!)

I have the pistons that look like those but my pistons do not have valve reliefs

now please leave for another 5 days

 

Yeah...ok. As if there aren't a ton of pics of true flat tops out on the internet.

Do you know what manufacturer or part number your pistons may be so someone can seriously answer your question? Or are we to, once again, attempt to weave our way through the scant gray matter lurking within your skull to give you an adequate answer?

Well since you asked so politely...............no. I rather enjoy watching you writhe in agony while searching for answers which you won't understand anyway.

 

STOCK

And no, there arnt a whole lot of pics of stock pistons for roller motors.

how about ignorant comments instead

:rant:

 

First: stock 302 roller cam engines are not 8:1 compression. Depending on year model they range from 9.2:1 up to 9.4:1 compression. Let's call it 9.25:1.

Second: a true flat top in these engines will likely raise the compression ratio to approximately 9.7:1 with the stock E7 cylinder heads.

Third: a true flat top will limit the amount of camshaft lift you will be able to run due to lessened valve to piston clearance.



Happy now, Junior?

 

yes, thankyou
very informative:Handshake

How come you cant be nice
Im no chevy guy trying to race you at the track

 

OUCH!!!I thought this was a place to get help, not be pickd on for being misinformed or not quite knowing all there is to know.

 

In order to provide ACCURATE help there needs to be proper information provided in the first place. Simply dropping a post with something like.......

"Hi...what's a good cam for my car?"

.......is not going to get you anywhere. Some will begin the long, drawn out, painstaking path of asking you questions concerning year model, engine size, cylinder heads, carb/intake, transmission style, rear gear, tire size, etc, etc, etc.

Then there are beings such as myself that will simply counter with......."Oh...you have a car?"

Justin and I have been through this once before on his fifteen-hundredth camshaft thread. Information is necessary.....assumptions and blurted out bullsh!t will be countered excessively with a healthy dose of condescending attitude.

Have a nice day.

 

I'll certainly be sure to try and avoid thehope you have a good day!
