68fastback Posted June 19, 2006 Report Share Posted June 19, 2006 : This article caught my eye. Ford modded a 4.6 terminator with FRPP parts for 690HP (601 rwHP). I find the article interesting because these same mods on the GT500's 5.4 base should yield about 750HP. They cost aboyt $13K. Article and complete list of mods imake a nice outline for a 10 sec GT500 I think. ;-) 690HP 4.6 Terminator -- by Ford/FRPP Parts list is at the bottom of the article... : Link to comment Share on other sites More sharing options...
kaylan1521 Posted June 19, 2006 Report Share Posted June 19, 2006 I like it, but not impressed with this part. ...... Sounds familiar doesn't it? "That severe traction problem keeps the Mustang from setting any quarter-mile records. We recorded a best run of 12.8 seconds at 120 mph, and our best 0-60-mph time was 4.7 seconds. We have no doubt it would run in the low 11s with real drag slicks. Impressive when you consider it has ice-cold air conditioning and will idle in traffic all day long, and it made it through a very abusive week without one mechanical problem" Link to comment Share on other sites More sharing options...

I'm wondering if the cams they used aren't just the ones already on the FordGT heads on the 500 and I suspect the shorty tubes are the same Foose used in the one-off GT at Ford HQ. So many sweet parts available for the modular now. I was thinking... a +/-750HP 'sleeper' 500 is something you probably don't want to kick-it-down with at 65 on the freeway -- even at 3900lbs and 57/43 ;-) Don't know if you've heard of CAV, a serious South African builder of gorgeous replica GT40s with frames/susp all done in aluminum. With a n.a. modular, they weigh in at about 2350 (not a typo -- amazing what not having to meet current crash standards can permit!). Ok, so a steel modular, blower and intercooler would add 350lbs max, and in all the right places. That's a 2700lb rear engine car with only 3.6-3.9 lbs/HP (750/690HP)! That scurrying sound you hear is Z06 Lingenfelters looking for cover ;-) Sometimes I do wish I had money. Link to comment Share on other sites More sharing options...
DVS2XS Posted June 19, 2006 Report Share Posted June 19, 2006 Realize that the 4.6L Terminator engines had VERY nice Manley rods - the GT500 5.4L does not. The rods in the GT500 are a lot more like (if not identical to) the rods in the 5.4L lightning. A weak spot. Link to comment Share on other sites More sharing options...

The rods in the GT500 are a lot more like (if not identical to) the rods in the 5.4L lightning. A weak spot. Yeah, that's what I've heard, Wayne, and apparently there's a lot of them holding up very nicely at 500-600HP. Are the 5.4 Lightening rods (non-Manley) H-beams or conventional I-beam design (more likely, I think)? The GT500 rods use the Ford 'cracked-powder' technology, and the early literature says they are forged-steel I-beams, but I thought I read elsewhere that they are an H-beam design (like the Manleys, anyone know for sure?), which more effectively spreads the load where the rod shaft meets the journal, the typical point of rod failure. And the truly perfect roundness of the cracked-powder technology does reduce bearing stresses by virtue of a precisely consistent oil film/bearing gap. So, I would not be suprised if the cracked-powder forged rods on the GT500 are just as strong as the Manleys -- at least it would seem foolish to use the Lightning rods if they were a weak spot with considerably less HP, but, who knows? Anyone know what the 4.6 terminators were factory red-lined at -- I'm guessing 6800 or so like the '01 n.a. 4.6 Cobra (which used cracked-powder)? Just curious... The 4.6 is such a sweet motor. But, yes, 750HP might be a bit much for a stock GT500 bottom-end Not clear to me what the design point of the motor itself is though NYIAS GT500 Ford rep was clear that the drive train was good to 650HP. I know the GT500 crank is forged steel. Anyone know if the Terminators were also forged steel cranks? <sorry for the stream-of-consciousness post -- brain stuck in low gear today ...lol> Link to comment Share on other sites More sharing options...
