I thought I would share this article because it is informative with regard to the power limitations of the 4.6L engine. A lot of it is old hat but theres some good information on the piston design. It's also a bit Steeda bias but hey they did their homework.

Nice read, thanks for the link.

 

Interesting, thanks.

 

Keep in mind, like all car computers, they 'learn' based on driving habits, changes in air/fuel mixture, etc. So a small mod like an air filter you can disconnect the + battery for a few minutes, then reconnect it. The computer will then recalibrate based on the new info. But we all know a new tune is needed on the S197s anyway, so might as well reflash.

 

Thanks for the great article. Since my next step is to lower my GT.

 

Great Article,

I think I want to keep my Saleen SC application to around 400hp... I guess that is why Saleen settled on 4-5psi with a water to air intercooler...

I keep wondering if it is worth just putting forged internals in when the SC is installed to avoid block/cylinder/valve damage...

 

Eventually u will get used to the power at 4-5 pound and will be tempted to up the boosts. Do it right the first time if u have the money and crank up the boost to 8-10 pounds , should be a beast. Good Luck

 

Good article on the sport springs, maybe I will try them since I won't have to do all the other mods. or do I?

 

It said the 03-04 cobras have a 4.6.....i thought they had a 5.4?

 

nope 03-04 cobras had supercharged 4.6s, 2000 cobra Rs had the 5.4

 

Good read.

Quick question, do the S197s have a two-piece rear axle, or should this have read two-piece driveshaft?

"Orlando says the '05 GT's Tremec 3650 five-speed manual transmission is a great transmission with stout gears. There have been no issues with the '05's two-piece rear axle, which is utilized mainly for NVH (noise, vibration, harshness)."

 

Nice article.
