No, because Mustangs (I get your point about arguments sake but that's not what Mustangs loose) will loose between 22-18% hp with an auto, and 18-15% with a manual, to the rear wheels. That's average, an auto could be as bad as 25%, and a manual as bad as 20%, but those are rare cases.

10 bhp = 8.2 -7.8 rwhp auto
10 bhp = 8.5 - 8.2 rwhpmanual


Still too way high of a number for a cai, maybe a set of U/D pullies on a good day, but not a cai.

 

I am talking 96-98 Singleport.

Now something to keep in mind is that the 96-98 had a small 60mm tube to the airbox and it was ribbed, then hit the maf screen, then hit the filter. (The reason why I dont say 94/95 isnt because there is something vastly different, its just a differnt power rating (145 VS 150) and honstly I felt no change on my 95's sixer.)

the 99-04 had a larger 70mm tube from a 60mm throttle body stock and went through a revised airbox (not dramaticly revised.) It was still ribbed and had a maf screen.

Horsepower ratings arent going to increase too dramaticly between the two because each one is suited for the TB its going into. I dont think there would be much more gain in a 99-04 over a 96-98. The intake really comes together when matched with a larger TB which is the bottle neck. I really havnt done any runs with a differnt TB yet because I havnt felt the need to change from stock untill recently.

I dont know how much that helps you but it makes sense.

 

Still close enough.

And would you agree that certain engines are assembled to exact clearances and produce more power than others going down the same automated assembly line?

I use to hot test rebuilt engines all day for a company called SRC and we would see variances of up to 20hp between motors of the same engine. Im not saying that as my supporting argument but its another little tid bit to think about.

 

Makes perfect sense. In fact, 94-98s (despite the 5 bhp increase that's debatable) have the same sizes. 60mm tubing, 70mm MAF, 50mm TB. Don't knout for sure about the 99+ intake size, but the MAF is 70mm, and the TB is 60mm as you said. Also, the tube is ribbed on the outside, but the inside is smooth as a babies bottom. It was like that on my old sixer, and my 5.0 as well as my buddies 00 V6 he had, and a buds at work 06 GT.

 

I know that two, which is why some stock sixers are able to run low 15s with God like drivers, and others strggle to run low 16s/high 15s. However, "GENERALLY" speaking, most new engines will only vary 5 or so hp, but there are cases when they hit the extremes like 20 hp variances.

 

My 95's was ribbed on the insude.

 

Actually come to think about it so was the 96'

 

Hmm........ strange, all the ones I played with were flat. When I uninstalled my stock set up on my 98 I had it in my room, and I read a post about the inside being ribbed, and mine was flat. My GT was the same, as well as all my other buds cars. Must just be a 97 and back sixer thing, becuase Ford did make a few changes to the 98 sixer, not many, but a few.

 

Actually I would be willing to bet that its 97+ that went smooth because 96' was a really od year that had its own gasket sets, slight variances in brackets, altered PN's for accessories themselves (Though they interchange) If you check with autozone it goes 94/95, 96, 97/98, 99/00early, 00late, 01/03,04
Funky funky funky. You would think they could save money by keeping the same design. The reason why things changed in mid 00 is because of engine ballancing and that ballance shaft above the lifter valley.

 

Hmm.....well my 98 was still flat inside, and an 99+ intake will not work on 94-98 models, difference angles and what not. Must just be one of those weird manufacture things where some are flat and some are ribbed.
