High voltage ratings and noise immunity ensure reliable operation over various environmental conditions. The combination of an advanced audio controller IC with MOSFETs fully optimized for audio performance results in improved efficiency, THD, and EMI, allowing the IR43xxM family operate without a mechanical heatsink over a wide power supply range on either a single or split power supply. The new devices integrate a PWM controller and two digital audio power MOSFETs in a single package to offer a highly efficient, compact solution that reduces component count, shrinks PCB size up to 70 percent and simplifies Class D amplifier design. International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the PowIraudio™ family of integrated power modules for high performance home theater systems and car audio amplifiers. Hope i didn't make anyone hate me.EL SEGUNDO, Calif. A stock 5.0 motor revs faster than any low HP V8 I can think of. Oh yea, the 5.0 motors DOES rev like a monster, expecially once force induction is installed. Some of them can be made to be bearible (to me) but the sound of a carbed ford is like nothing else to my ears. I think i'm going to go with a SBF hybrid because of the SOUND. Personally i didn't know that the SBF was lighter than the SBC. And with a good build you can hit any HP amount you want. I've seen people get 800+HP on the stock short block. The REAL beuty of the 5.0 motors is that there is no lack of parts and aftermarket support is plentful. A good 340 Fly wheel HP 5.0 will cost about 3500. I've seen some really cheep crate 5.0 motors but you gotta question the quality. ![]() I've always thought of them as a mid-priced engine. So if you look at crate prices then the 5.0 isn't totally cost effective. But it's also very easy to get a lemon of an engine. It's easy to find a "decent" donor car to scrap a motor from. ![]() I think you get what you pat for with a 5.0 motor. I agree with everything else you said, btw. If someone is non-techy they could always go carb'ed. Curious as to why you would want to change intakes? Stock intake should be good to 350hp. Check Anderson Ford Motorsport, they sell a PMS used to change parameters. I still want the 5.0 but I dont believe at all that the EFI is "better." If you are allergic to computers then you can get a timing adjuster and larger injectors along with a "re-tuned" MAF for the 5.0, in which case for someone non-techy then yes its "better" because there are bandaids for you if you scream when you look at timing and fuel tables.Īctually, the EEC-IV processor can be "Intercepted". Either one could benefit eventually from a larger TB. The intake on the 5.0 should also be replaced, where the LT1 intake does not need replacement. I would agree the ignition is better than the Optipuke but no way do I think a virtually unprogrammable EFI setup that is older' date=' is somehow "better." I dont think the horrible aero of the Mustang was completely responsbile for the gas mileage disparity, and the fox body was certainly lighter to boot. Smaller engine that gets worse MPG and an older EFI setup is somehow better?
