superharged and stock headers???

[sharptech]

Just curious how many of you are supercharged and still running the stock headers? I'm at that point where I've got full catless exhaust except stock manifolds, and power delivery still feels really good on the stock headers. From two days of researching, it sounds like when supercharged, scavenging is irreverent and it's more about cfm at that point, which our stock headers do alright. I'm only going for 600whp-675whp, and I understand eventually you need to go headers, but even the roush phase 3 is on stock headers. Just more curious what you guys are running?

The stock parts are pretty stout on these cars.
I still have stock manifolds and stock over the axle pipes amongst other things.

 

[sharptech]

Holy crap! Your stock manifolds and axle pipes and your running 9's! Are you using a cutout?

 

[mitchster]

I am running stock headers. I just had Borla do the exhaust system. X-pipe, axlebacks and Borla "S" mufflers. One step at a time. Next up brakes or Stage II.

 

[sharptech]

I'm still running them at 11.5@130mph and all seems well. I'm thinkin of dropping to a 3.6 pulley and just run 93 I'm just curious if I'm choking the motor out.

 

[corepwn]

I don't have any cutout.
Stock manifolds -> Lethal OR-H -> Stock OTA -> GT500 Mufflers.

According to your 130mph trap, your making good power... Your car should be in the 10's, I'd work on then rest of the car before you worry about adding more power...

 

[sharptech]

ya you have a point Scott, I could really use a stall. that and our DA is in the 4400ft range most the time.

Stock almost everything here too. I have cat deletes and an axle back.

 

[92fiveohfox]

I doubt you will see much difference until 800 rwhp.

Wow, looks like I will be spending my money on better things, like a stall converter, and smaller pulley. That's so crazy you guys are making that much power on stock headers. Guess key word is "headers."

Dude, you're trapping 130 and only running a 11.5.

Work on the rest of the car (I.E. suspension/tires) before you add more HP.

I picked up nothing with kooks shorties so put the stockers back on. I have cat deletes and x-pipe but stock ota pipes and mufflers

 

[stangn]

Stock manifolds and over axle pipes. Off-road X and borla mufflers. Making mid 600's on pump gas.

Stock headers, Vortech, Pypes H pipe, stock over axle pipes, GT500 mufflers, 10.19@134

And with a bum trans lol.

 

[kona 199]

how many 10 sec. passes did the bum tranny make?

 

[kona 199]

stock headers are pretty good.

 

[Blazer707@TBR]

how many 10 sec. passes did the bum tranny make?

I would say 10-15 10 second passes with the trans acting up. Still was running 10's when it was pulled.

 

[Tgpatrsn]

28 passes
