With the mods in my sig can anyone give me a ballpark guess on what I should be pushing hp wise? I haven't had the car on the dyno since I bought it but plan on going soon

 

If you still have a stock converter, you might make 350-370 rwhp. Put a stall on it, trust me, you'll love it! It'll multiply that torque on takeoff.

 

She's got a stall. Sorry I had to update the sig. Added a bit more to her lol

 

You still might see 350 at the wheel unlocked. What will be a bigger number is that torque, especially with the stock ls1 cam, which came from the vortech 6.0L truck engine. My original stock ls1 with a 3500 stall, stock exhaust made 298 rwhp, 348 rwtq unlocked. My guess is you'll gain 50-70 at the tire with heads, exhaust, and intake over mine.

 

Sounds about right to me. Really need to get her on the dyno after I decide which cam I wanna go with.

 

Well, as for that, my '01 has a 383 with LS6 heads, American Racing 1-3/4" LTs, 3" y-pipe, 3" cutout with an awesome Comp Cams 230/236 114+4. Love the sound and idle. With the stock displacement, you might do a 224/230 114. I drive mine everyday and wouldn't recommend anything crazier than a 114 LSA. That's coming from Geoff at Next Level Performance, who knows his stuff. I hit the dyno tomorrow morning at 8:30 am.

 

I want somethin fairly mild mannered and streetable but still hase a nice lope to it. Let me know what she makes

 

Definitely will do.

Hell ya. Any plans for more power?

 

Absolutely yes! What I'm really impressed with is the way the cam changed the power delivery. It isn't as instant as a higher torque cam, but it carries that power all the way to the top, 6500 rpm. I thought wheelspin was going to be an issue, but with the 8,000 mile treadwear on the nittos, it isn't. Definitely has me planning on cnc'd heads and a FAST 102. Ty, the mechanic at Next Level was telling me " You're probably one of those people who don't stop adding power!". He's right. I got a taste, and I want more. With fresh tires, drag struts, and 450-470 at the wheel, I might be pretty satisfied. And, it definitely pulls from a new Camaro SS. In the graph, RED is before cam + exhaust + inj.

 

Badass bro now I see a little bit of FI in the future lol
