Bullet Proof

So I have a 99 frc Whats the safest and cheapest way to 500-550 HP My thoughts were

kooks 1 3/4 headers no cats
afr 205 heads
G5X3 cam
fast 90/90
vararam

anyone know what this will yield? trying to add up if I want to do this or go FI. I'd really like to have a H/C contender if possible.

I'd like to keep it safe and reliable but I may have to add a 100 shot of NOS...but I really don't want to

Why reinvent what others have perfected? Depending on where you are in the world (sorry, I didn't check) find one of the forum vendors / tuners and ask the same questions and then compare / contrast and choose. I selected 21st Century Muscle Cars in Carrolton, Texas (Dallas) for my 2000 FRC. See sig for details.

Just an opinion,,but 500-550 NA on a stock block,,can be done,,but I think that would be pushing the limits. Low end would probably suffer and overall drivability wouldn't be the greatest,,after all you are dealing with only 346 c.i.!! My suggestion would be turbo or one of the superchargers,,more than likely a centrifugal like Pro Charger. Screw types are usually biased a bit to more bottom end than top end,,whereas centrifugal builds a bit more top end. Just my 2cents,,,your results may vary!!

A good S/C kit like one from A&A will get you where you want to be while maintaining your stock driveability and good mpg.

Is the A&A setup smog-legal here in the land of the smog-police? I know the supercharger has an exemption, but what about all the other nice little add-ons like the air intake, intercooler, blah blah blah. Is it certified as a complete kit?

Thanks.

The Vortech SC in the A&A kit has a CARB number. As far as the A&A kit as a whole, suggest you contact them. In addition to the kit, there are other things you might consider adding when getting an SC. I'm not aware of intake manifolds and throttle bodies with CARB numbers. I think some short tube headers are smog legal, but not sure if they have CARB numbers. On exhaust, main thing is to keep the cat converter and avoid long tube headers. My understanding is if properly tuned, you won't have a problem with the emissions part of the smog test, but you could have a problem with a real nitpick visual inspection. Finding a friendly smog check place is desirable.

Your best bet is to call some of the shops in Calif that do mods and get their opinions on the smog test impact of various mods.

Andys new kits are awesome and when you are ready to upgrade to more power you will have the kit you need for this. Get in on one of Andys kits and you will be in boost heaven

You didn't say "rwhp", so I assume you mean at the flywheel. All you need is 430rwhp to meet your goal. There are lots of ways to achieve that with a very tame/streetable combo. You don't need the "best of the best" to get there. In fact, you can do it without heads pretty easily but you'll sacrifice a little driveability.

Completely smog legal here. 32 mpg fwy too

lil vette

150 shot nitrous, cold air, transgo, magnaflow cat back
& dynod= 431 rwhp
.

I should have clarified. No smog inspections here so no cats. I was wanting 500 rwhp not at the flywheel. From what I've read I believe the lower will handle 500 hp...550 is pushing it?

If you go with a Vortech S-Trim blower and some headers you will get 500 to 550 with know problem. Talk to Charlie at RPM-Motors Inc. This blower is a top end blower so if you want something with more at the bottom end look at the Maggie. For the cost though you would be better with the Vortech. Hope this helps with your question.

Tech

Heads/cam can get you there... but it'll be a "max effort" setup. Supercharger or nitrous can get you there with less driveability concerns. Do you just care about a peak HP number? What are you going to use all of that power for? A modest H/C combo plus a 100 shot will be easiest and safest, IMO.

My friend had a setup like that, his engine now fits loosely in a 5 gallon bucket. He started with a 75 shot, then 100, then 150 and I think he did 200 which caused the "5 gallon bucket" thing.

The rockers are unnecessary. Forum vendors can put together a better combo and perhaps save you a few bucks.

Mister Peebody

I don't think you'll get 500-550 with heads and cam for less than the cost of a blower.

Just got researching the exact same thing for the LS6 I am about to put in mine. With what you quoted you are looking at around 490's rear wheel depending on your exhaust. You might want to think about the supercharger...just might want to think about investing in a leak down test to make sure your engine can handle that stress since it isn't forged...

Simply put the H/C set-up you want will yeild 430 RWHP or a little more and after you enjoy that for a month or two you will be craving waaaaaaaay more - it just wont satisfy!

Here is a sample of my buddies Stock '04 MN6 LS1 with Kooks headers, Hiflow cats, Xpipe and Tubi exhaust:

P1SC-2 with 12 PSI of Boost
Methanol Injection
42lb injectors
Gauges
NGK TR6 plugs, MSD wires
Dyno Tune - 2 BAR SD Tune w/MAF

559 RWHP and 500 RWTQ on a stock motor!

You can't beat that, go to A&A Corvettes and look at their complete kit, install it yourself and have it tuned and you'll have 525+ RWHP with only bolt-ons and yes a SuperCharger is a Bolt-On set-up

Thanks,Matt
