[updated:LAST EDITED ON 08-Jan-02 AT 01:23 PM (EST)]I am going to buy a new Class C RV built on an E-550 chassis in the next couple years and trying to figure out when and what various technologies will be incorporated into the E-550. Please give me any info you know, thanks.

What I have found:

5-speed auto: This seems like a nice thing to have from the BON info, http://www.bonforums.com/powertrain/trans_new5r110.htm. Seems like this should be in the E-550 mid year 2003 or latest the 2004 MY ?

V10 enhancements: Seems like the V10 may get the 3V enhancements the 5.4L is getting. Don't know how much or when. Seems like the 5.4L is getting:
3V - 1 in and 2 out ?
VCT - variable cam timing
Dual spark plugs
IAFM - ?
ETC - electronic transmission control
Electronic returnless fuel system
One person guessed the 3V will raise the HP/Torque from 310/425 to 350/500. GM's 8.1 is 340/455.

42V Battery: I have not found any info on any Ford products, but this would be a great addition to RV products. More info at Delphi, http://www.delphiauto.com/pdf/DE99E100.pdf


Thanks

Here is some info on the E-550 for those who have not seen it.

I can guarantee the 3 valve head will be 2 intake one exhaust.


I wonder why the PSD is neutered so bad in the vans.

 

"I can guarantee the 3 valve head will be 2 intake one exhaust."


In another forum I was told that they believed it is 1 intake and 2 exhust. Their reason being is that if you've ever put a high flow exhaust on a car, you may find that if you relieve too much back pressure, you loose low-end torque, too much restriction and you loose horsepower in higher RPM. VVT is a good answer to this problem. It operates as a 2V engine at a low RPM to give optimum torque output when accelerating and when pulling a heavy load. In most cars(equipped with VVT, (Or V-TEC as Honda calls it), the secondary out-takes open up around 3,200 - 3,800 RPM allowing more air flow increasing horsepower and torque at higher RPM.

Using your own explanation(which is correct) why in the world would you need 2 exhaust valves on a low RPM truck motor????

Every 3 valve head EVER(which includes Mercedes benz, Honda M/C and cars and there are probably a few others I've forgot) use 2 intakes and 1 exhaust.

I'm also assuming the only motors with VVT or varible intake (in the case of the Ford Cobra motor) are 4 valve motors.

 

I am bumping this back to the top in the hope of someone knows so more information.
