According to Car and Driver with cams and heads the motor will be able to spin to 7500rpm!!

 

wow, thats a nice looking peice!

 

I thought I read where the valve train can't take much over 6800...

 

i agree, i think to get to that 7500rpm safely the vehicle will need upgraded valve train and upgraded bottom end. just my 2 cents.

 

New heads with cams and associated valve train will solve this problem. The stock manifold it didn't make sense pushing the car above 6800rpm anyway as the car ran out of steam. On a stock car this manifold probably won't be worth much. The CNC heads, some nice cams it will make a nice piece.

The stock bottom end from what I have read is good to 7500rpm

Kind of reminds me of the NA 4V 4.6 Cobra/Mach 1 or actually the '00 Cobra R piece. Like one of the comments on that article said, wonder how much low end torque is given up for the improved high rpm breathing? Still, nice to see Ford isn't totally abandoning the 4.6 3V with the advent of the new Coyote V8 expected for 2011.

 

Definitely reminiscent of the Cobra R manifold.

very interesting.

 

With the extra rpm available and some 4.10 gears you won't even miss any loss in low end. Also, who said cars with no or lowe end torque can't run. The new E92 M3 only makes 295ft/lbs of tq. from an engine that makes 414hp, yet it still can run mid 12s at 113mph.

It is nice that Ford isn't abandoning the base of the S197 crowd.

someone already ran a back to back test and picked up next to nothing on a full bolt on car. The only nice thing about it is its still plastic so it shouldn't heat soak as quick

 

I saw that on another forum. I want to say it was 3 or 4 HP. The stock intake works real good on a NA engine until 6000 or 6500 rpm. You'd probably have to go North of that to make some serious numbers.

 

It seems highly questionable that a complete head/cam/intake swap was done with no performance increase, so I assume you mean it was just an intake swap? Either way, I blame the driver.

 

just an intake swap. How do you blame the driver? The car was strapped down to the rollers made 3 passes had the intake swapped while still on the dyno then made another 3 passes. Then he took it to the track and was still running the same 12.0x's as before the intake. The stock 3v intake works very well. Not one of the 3 aftermarket manifolds that are out are worth anything on a bolt-on car.

 

Who is this tester that you speak of? Is it Matt D from the S197 board? If so he DID gain some RWHP with the FRPP intake, not as much as one might hope but there was still a gain. I think that Ford actually did a really good job with our cars. The exhaust and intakes are solid and yield minimal results when changed out.

 

Yea matt he picked up 3 or 4 hp like mentioned. I guess you can consider that a gain but is it really worth the $600+. Don't get me wrong its got its place, I was just pointing out its not going to help out 99% of the people on this board.

 

So you’re saying that the engine was spun to 7500 RPMS with the stock intake and then with FRPP and that there was no difference in power on the dyno??

 

Sounded like it was just a bolt on car...which does not include heads, cams and such. If thats the case the stock intake is more than enough.

how many heads cam 2010 mustang are there reving to 7500rpms are there on this site? None? Thats why I said it won't do anything for 99% of the people here.No wonder why people think this site is a joke. Your just looking for an argument using some off the wall combo that no one has.

 

 

Yeah my reading comprehension fails me, LOL
Thought that the car had internals for some reason. That’s why added the? Guess I read to quickly.
Personally I like this site, not that many D-bags like you would find on other sites.


On another note I did have the RPMS up to. (Look below)A few years back before the combo was sent out to get built for boost.
I guess it’s safe to say there was at least one 05 that’s been spun high.
IMO, I would like to also note that if I where having the engine built for high RPMS, the only shop that would trust with a project like this would be BOSS330,

 

The build I'm talking about was a naturally aspired (NA) engine with bolt ons (so yes, I'd say heads, cam, CAI). I looked around but I couldn't find the thread so I cannot confirm all of the mods. He was looking for the best ETs on a NA engine. This guy was spinning the engine to 7000 plus rpm.
