Is a supercharger without headers worth it?
Is a supercharger without headers worth it? I am considering again a supercharger, but am not sure if it is worth it. I have a TR224 cam, a bullet muffler, a lid and a 3500 stall ... but no headers. Is it even worth getting without headers?

Sure..... Good power can be had wihout headers. It's just not a max effort build, and of course you'll be leaving power on the table. I'm considering a build myself without headers. Albeit for different reasons than you (CA smog regulations). However, with stock internal limitations I'll run no more than 8psi and at that level I'll be losing out on about 30rwhp.

Years ago I had one of the first P1SC LS1 f-body prochargers out and I put it on a 2000 z28 with stock manifolds and all emissions parts intact. Tuned it with 38lb injectors using a MAFT and a HPP3 (no LS1 edit at the time) and ran 11.70s in the 1/4 with it fill weight with ET streets. Made 420ish rwhp with a locked converter (ST3500/3.23 rear). Put a set of MAC headers with cats on it and the car ran 11.30 @ 121mph with no other changes and made 486rwhp. The car was a little richer with the manifolds but the headers really woke the car up.
Big difference for the money but the car was still plenty of fun on the stock manifolds/exhaust.

definately worth it.....
I bolted a P1SC-1 onto my 2004 GTO, everything else being bone stock, after a Jeff Creech tune she put out 450/411....little over 150RWHP gain, still got over 25MPG on the highway, drove like stock around town...but power was there when you wanted it!!

Just my .02 but why are you running a camwithout having headers... That'll help that tremendously, but you don't really need to run headers with a supercharger, the velocity of the air increases and is not as beneficial some would think... Atleast thats what I read in a few recent articles.

because I bought it that way
Unless you are into racing in a certain class forgetabout it. Headers are there to help squezzzee out as much power as possible. Sure headers will wake it up, but if you don't need to then why spend the money? my .01$

+1 for hell yes it is worth it. As a side benefit, if you later decide to get headers, the gain will be even more noticeable. Just because you can't do a max effort combo all at once doesn't negate the benefits of each component.
If money is the issue do the headers first, save up a little longer and THEN do the blower. It will be fine without the headers but why not wait a few weeks longer to make another 40+hp?
