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.

Why no headers?

I would get headers before going to all the trouble of a supercharger

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.

How much boost were you running on those runs. Can you remember what you traped before the Mac's?

Thanks. Scott

I dont remember really, that was 6 years and a dozen cars ago but I would say 114-115mph before the MACs. It was the 'big' 9psi kit and I think I seen 7psi on the gauge if I remember. That was huge boost back then on an LS1

Before I went crazy with modding I had only the charger on. Hell yea it's worth it. Headers are just one more mod ie heads, cam, stall, etc.

Remember the engine as an air pump. More air in, more air out. It will still work w/o headers but will not be as efficient powerwise.

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.

headers aren't expensive and aren't that hard to do. do both at the same time and have a nice open exhaust too.

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$

It is worth getting forced induction without headers. I originally planned to get headers installed with the Procharger but decided against it and have no regrets. My car has 472rwhp 447rwtq with stock cam, 1:85 ratio rockerarms and 7psi.

Nice numbers...... And welcome

+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.

Its worth it but why do the sc before the headers?

unit213

Just do the headers at the same time and have it tuned once.

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?
