I've been pondering my goals for my truck. If I go FI eventually I want a system that can support larger HP (500+). Are the only carb approved FI systems the p1-sc and radix? What ever happened to the sts being certified?

 

does the sts need to be certified since you dont mess with anything but the cat back. i thought that kit was good go without certification.

 

I think anything that messes with the intake or Cat location must must be certified. If the STS gets certified it will be the only bonafide way to make huge power. I've heard of guys running the procharger kit with the d1, which is not carb certified but some smog techs won't know the difference between compressors.

 

I'd say the most likely way is to use a blower and then a shot of nitrous The P1 and a nice 100hp shot should be able to get you where I was with the STS and big boost. At least I would think anyway. The really fun way would be with the Radix and a big shot but traction would be a total bitch. LOL

 

i always thought a radix on something like a 370 with a direct port 200+ shot would be a prety simple and bad *** set up.

 

That's a manly setup right there bro!

 

are those flp headers awith y pipe ca leagal? they came with cat test pipes too i think. that would be a good way to exhaust that project if ca leagal.

 

What do you mean when you say big power? What are your plans for the truck? Race only, street? By the end of the year I will show you a 525 rwhp stock bottom end 5.3L.

 

Blown- I think your set up would be perfect with a 100 shot. By big power I'm mean around 600hp streetable. F-body fast car fast. Has anybody tried spraying a decent shot with a blower? Can you do direct port with the radix on top of the intake?
