hey guys which do you think has the potential to make more HP, the coyote 5.0 that we are getting for 2011MY or the current 4.6 3v? Obviously hands down when comparing N/A the 5.0 would be better but what about FI setups and so on? Pros and cons?

 

It all depends on the CR of the new 5.0, which I have yet to see any info about it.

 

Someone posted a while back it would have 11 to 1 compression and a 7000 rpm redline. I was a second hand post from someone "in the know."

 

A SC 4.6 vs a bolt on high compression 5.0 will probably be very similar in hp #'s you would think. But who will win in torque?

 

this was a topic right before the site went down, and there was alot of opinions. i hope some of the people in the previous thread will make there way over to this one and give there opinions.

i would have to say the vehicle with the higher compression will have the edge in torque numbers. just my 2 cents

 

If its near 11:1, my assumption would be that new heads would be necessary to be able to feed it some serious boost.

 

the higher the compression the more likely the engine wont be able to handle alot of boost.....supercharging and higher compression motors usually dont mix well.

 

Usually. But the Corvettes make some nice power with boost.

 

a corvette is a superior sports car, ford will have to do this right for us to make nice power with boost.

 

That was what I was implying, if you want to boost it, replace the heads to lower the compression and then crank up the boost.

 

oh im sorry, i missed your post my bad. but my response to you is that its a awful lot of work just to boost the car. so hopefully ford has a way where we are still able to boost and not worry as much.

 

I'm sure that it can be boosted in stock form, just if its high compression, might only be able to run 5 psi.

Also look at it this way... The current V8 can be boosted to 400-450 safely from what I have seen. With this motor already putting out 400, it may not be necessary to boost it for the vast majority. While I do like the power, I really don't need even 400. I would be more than happy it it only makes 350, as I don't plan to drag it... (plans may change)

 

I can't see Ford putting out a motor that couldn't handle significant boost. SCing is a given with the Mustang. I mean even Ford offers a factory/warrantied SC.

 

You don't need to replace the heads you would just need thicker head gaskets and stronger head bolts/, this should lower the compression.

To crank up the boost and be safe it would take new pistons.

 

would be cheaper to do the heads. your talking about stripping down the ENTIRE engine just to supercharge/turbocharge your ride.

 

When I said "replace the heads" I was refering to the piston heads.

 

I rather see a GT motor that has high compression for once that can make enough N/A power to keep up with the competition even when extensive modifications(like heads/cams) are added into the equation.

 

should of clarified, thats a big difference. depending on "cylinder" head work, compression ratio can be altered as well.

 

I'd really like to see this new 5.0 be capable of over 400rwhp with a very streetable cam, full bolt on's, and full exhaust, but for now, that is just a pipe dream.

 

Better late than never.
