Ive got a 03 ls6 , thinking about a&a superchargering it, but its got a brian tooley stage 3 cam and 11.1 compression, headers,4.10 gears, want to put 500 to the wheels , is that cam and compression going to be a problem if i keep the power to only 500 rwhp.
Thanks

Ditch the gears add methanol injection good fuel system and a good tuner and have fun.

I have close to 11:1, 230-112lsa, a4 w/ 3.42. And 4000 stall. 6-7psi on pump 93 (usually run octane boost or get KR). I still use the low octane table which a vast majority of FI applications don't.

I never understood why people frown on gears with a supercharger. If it was fast without the SC it will be fast with it.

MVP'S ZO6

I don't frown on a lower gear and I'm not saying you can't run "more gear". I understand that two cars who's only difference is their gear ratio that the one with "more gear" will be more powerful. I'm simply saying it's not needed as the blower is going to effectively increase your power output. In addition in most of these cars which spend a lot of time on the street and not turning "high RPM" more gear usually makes for a car that is not as nice to cruise around in. In addition, let's say you're at a race track and you have Two cars where the difference between them is RPM. One car makes 1000 hp at 7000 rpm and one that makes 1000 HP at 8000 RPM; the one that can turn more RPM will probably make it through the traps with out bouncing off the rev limiter.

Cant change gears, just put them in 500 miles ago when cam went in, , i wish i could leave well enough alone and be happy with what i have, 425 to the wheels with 4.10 gears is a great feeling, but never enough, its a sickness
If all i would be running is 500 rwp on a very safe tune, would guages be necessary to start with, or can i wait a few months and then spendspend another 600.00 on guages and install?

reactor2

Yeah, if you have "the disease", you will never have enough.

I think with a blower and your current set up you will be WELL north of 500 RWHP probably closer to 600 and without a really good tire your going to be traction limited with the 4.10s I make 585/585 with 3.42 and 1st and 2nd will blow off once in boost and 3rd can be a little iffy when its cool out. If 500 is your goal you might want to consider a nice set of heads......it would be cheaper, granted you wont see 500 but 460ish with 4.10s N/A would be a fun ride.

I just looked up your cam specs which are 231/242 .617"/.592" 112+2 not really a blower cam but it would work. I bet the car now is a blast...is it a Z06 with M12 trans>??

Wickd1

No its a FrC with a m6 thats why i went 4.10s But even with the blower im going to keep power at 500 rwhp, i run toyo proxies now, its a blast to drive now,, this will give me more power than i can use ,, tire wise.

reactor2

You're going to keep the power at 500.

I'll give you 3 months tops before you drop the pulley size

I'm in your same boat man. I have a 99 FRC and just built a 408 with gmpp ls3 heads, stock ls3 intake and a N/A cam and believe my compression is 11.3ish:1. It makes 469rwhp which I was disappointed in. Don't even have 500 miles on it and already bought an alky kit and supposed to be picking up an A&A kit with a V3 Si from a forum member. Problem is I have 4.10s as well and alot of overlap in my cam. Oh well...time to trade the 345 invos for some 345 MTs and learn some more throttle control

Sirk17

I hated the way the MTs drove. I finally just said **** it and now run a street tire.

Wickd1

Yea the mt are scary as hell in the rain, on dry pavement they road fine to me.

Considered a bottle? The juice like higher compression.

Your gonna have a spin monster on your hands with those gears.

reactor2

Either juice or FI? Hmmm, I couldn't decide....I'm running both!

Atrain59

As stated it would be cheaper to go with a set of good heads and be close to 500rwhp.

But

Superchargers are a ton of fun! With AFR 215 heads, Cam, LS6 Intake/tb, FIC 850cc Injectors, Holley twin Fuel Pumps, 100% Meth and an ECS 2200-SL Supercharger kit I made 700rwhp and 623tq on 12lbs of boost.

2003Evo

That is not a blower cam, too much overlap...12.5deg of overlap for that matter. I would spray or do heads. With that much overlap you will be pushing the boost right out of the exhaust.

Wickd1

Thanks guys for everyones comments,
I was ready to change to heads and a fast today, talked to my tuner/builder today, and he still says lets put the AA kit on it
And put down 580 on a conservative tune. Hes says realistically with a $2400.00 set of heads, a fast 92 and a ls2 throttle body we might get 465 to the wheels
My head is spinning,

That's the ultimate truth of supercharging. Throw any kind of $$$ combo of H/C/I on a stock block, and you'll get 500 RW, if you're lucky. Throw a V3si on a stock motor with just headers, and get 550RW easily. I went through the whole gradual upgrade ordeal, trading old parts for new, and ended up SC'ing it anyway. Your gears are partially mitigated by a taller first gear, but traction WILL be a problem.
