Maybe in the market for this in the near future so wanted to get opinions on either of these setups.. Would like it to be DD but have over 500 rwhp. Would like to get into the 10's too. Thanks The car is an 08 LS3 6M.

By no means am I an expert at any of this, but there are guys running 10's with cam-only LS3's that DD them. You can get 500 rwhp with a cam and bolt-ons.

More HP doesn't always mean faster. Blower car adrenalin rush is undeniable but traction can be hard to perfect.

I wouldn't bother with those heads. WCCH and AI have some great CNC port programs for the LS3 heads. I would probably use AI since they are closer to you. If they mill the heads at all, you will most likely need to fly cut the pistons. You can get 500rwhp with ported heads and the G6X3 though. To get a stick shift car in the 10's takes a damn good driver and great shifting.

what is the ratio of hp/weight? meaning,superchargers add like 300lbs to a car...right? so how much would a cammed car with less weight need to make to be equal/comparable to the higher hp s/c car?

SlowVet05

I think it's more like 50 lbs. for a centri.

300lbs????????????

About 60-65 for a complete centri and 75-80 for a PD blower and you can make way more power with a blower than you'd ever make with a head/cam upgrade. Virtually zero driveability impact with the blower...not so with the head/cam package.

Still laughing about that 300lb number!...even a twin turbo kit doesn't come to half of that number!

honestly.... either direction i think would be fine and not to mention fun

maybe check out the new magnunsons that are due out

i haven't seen a SC that i like and would want to get for the wifes car
personally i've been looking for something that screams OBNOXIOUS sound wise, like an old school BDS 8-71
just figured, spending over 7k, we wanna hear it

You do know BDS makes an LS manifold for a 6-71/8-71 right? Adding their fuel injection and drive setup would get ya done. Hurry up. I want to see it when you are done.

PS. You could also bolt a Whipple to that manifold.

ok,300lbs is taking in to consideration head unit,piping,intercooler added coolant.....it all adds ups to way more than 50 lbs! think it through...

jon6.0

The roots water to air intercooled blowers are probably 100-125lbs. The centri air to air intercooled blowers are probably 75-100lbs. Easiest way to find out would be to email or call a vendor and ask for shipping weights.

So would I get more performance with SC even with added weight than H/C with no added weight?

SlowVet05

I know this is on a Z06, but I'm sure the kits a very similar.

Because even the lowest entry level performance numbers on a blower car start at around 500rwhp and it costs no more (in weight) to turn them up.

Motorhead-47

The Edelbrock kit is 104lbs of parts but you remove 31lbs (verified) of parts from the car that do not get reinstalled. The last A&A kit I had weighed 92lbs....that was the entire kit in the box as dropped off by UPS. There was at least 20lbs of packaging with that supercharger.

C U IN REARVEIW

I stand corrected,i was told that the ranged near the 300lb mark fully installed w/ fluids,ect.

I love the sound of a supercharger...cammed cars sound great too....pick your poison

old motorhead

500 rwhp without f/i is going to get old REAL quick in a DD. Mine got old with only 475rwhp. To hit 500 n/a, it takes a pretty gnarly cam. Those are better left to the weekend warrior types. Now, with TVS blower, mine has 650 rwhp and perfect manners. Way more power at any rpm I choose to use it.

Motorhead-47

DO BOTH!...I had a blower car with a mild cam...loved it!

STROKD

I had a 08 manual that made 501rw with the STOCK heads and intake untouched, never off the car... cam was similar in spec to the G6x3... made 645 rw on a 150 shot.. it was a fun and fast car, but if I bought it stock Id go with a supercharger.

I since sold that car and am buying a stock 05. I was in same boat as you and wanted HCI since my 08 ran so well. After a LOT of reading and research, I am going to have a blower installed and leave everything else on the car stock (except for a ported LS2 intake I have in the mail). Talking with ECS they think I can get around 525ish at the wheels for 7300 installed... the heads, cam, intake, exhaust etc etc come out to around 10k installed to make right at 500 rw... sure the motor setup will be quicker and faster at a track, but seat of the pants wont feel as fun as the blower, and it wont be as fast on the street above 120 or so.

The motor build would also be MAXED out unless I added a blower or spray, whereas the blower can have the restrictor removed, add meth, headers later and make over 600 rw very easily... can pulley it up and go for more if needed (which it wont be, I have another faster car I am building, I dont need a 700 rw daily driver.)
