Edlebrock Stage 2 Supercharger Kit - Questions...

[Motivology]

Looking to hear from owners who have Edlebrock’s Stage 2 SC kit.

According to the description of this kit online, it is intended for competition / race use.

Is anyone driving with this set up on public roads often / daily? Curious about the daily drivability.

Lastly, would this mess with the emission testings? I know it’s not CARB compliant for California emission testings, which has the strictest emission laws - but everywhere else?

Anything else that is important to mention about the kit, please say so. I ask because I see a Mustang with this set up and would like to learn more about it.

Thanks!

tons of people running SC on their daily's, the drivability will be in the tune more than anything else.

being in AZ - the issue jumps to mind of IATs in the summer will be very high and likely limit you somewhat

no emissions issues AFAIK

I know a ton of people run superchargers in their Mustangs. My question was specifically Edlebrock’s Stage 2 kit. That is supposedly be for competition / race only and considered ‘illegal' on public roads, according to their website and main vendors.

With that said, would I have issues registering the car and using it on public roads? Passing emission is another thing here in AZ too.

Regarding IATs - what would be max air temp it can handle conservatively?

@07 Boss For your question concerning emissions.

What's so different from the stage 1 and stage 2 kits? I'm assuming just the pulley is going to be smaller.

I was driving my car daily (until the oil pump went out) for years without any issues. I did go through tires quite quickly but otherwise, no different from any other car with some power.

CARB stands for California Air Research Board, so the only way it gets CARB certification is if it is legal in CA.

If you just have to do regular OBD smog testing you should not have any issues. If it is an actual visual inspection it will never fly. If they do OBD testing like in California it will never pass. It all depends on your state's or county's regulations.

Why the edelbrock kit? Why not a Whipple? Don't they make a CARB kit? Being in AZ I would look at the kit with the largest intercooler capacity. I'm in Vegas so this was a priority and went with the Whipple over KB and Edelbrock. Plus I thought it was the best looking kit.

Others have kinda covered it but the short answer is the stage 1 kit has CARB certification and the stage 2 kit doesn't. The "Competition use only" thing is to keep the EPA off their backs.

Frankly, I have not looked too deep into the differences between Stage 1 and Stage 2 kits. I found a Mustang online that has Edlebrock SC Stage 2 kit so I really haven’t dived much into Stage 1 kit.

I knew what CARB is - hence I mentioned that Stage 2 is not CARB compliant. But since I’m in AZ - that does not apply. With the emission testings, all I’ve seen them is plug into the OBD that is hooked up to their computer. Rarely seen them put cones behind exhaust tips for smog test (never for me, but have seen them do it to others - usually on older cars).

I’d imagine we’d have similar emission testings between our states?

Also - after a quick search, it appears Whipple does not make SC kits for 4.6L engines any more. I’m assuming you went with the largest intercooler set up due to heat?

That’s a nice SC set up you have.

Gotcha that’s what I kind of figured.

Only certain counties in NV do we need to get smogged and it is the simple OBD testing. You should be good then in AZ.

That's too bad that Whipple discontinued their twin screw. I thought it was the best at the time especially since it had the largest cooling capacity.

Thanks

For sure. I appreciate your opinion regarding emissions. I wish we never had to deal with this crap but thanks EPA…

U might want to look at Roush....and also DOB. You want a BIG HE on the front...or u will have issues even in milder 70-80F wx.
Unless it's a built engine, I would go easy on the power....esp if it's an older 4.6......with lotsa miles on it.

Got it. If I want to supercharge it, I would most likely build the motor so that it can handle it with ease and for reliability reasons.

The car in question that brought this to my attention actually sold quickly online. I kind of figured it’d be gone soon. But all of this is great info for me to learn and understand.

If you want the engine built, where would you go? I’m somewhat familiar with Roush, but not sure what/who DOB is?

What's so different from the stage 1 and stage 2 kits? I'm assuming just the pulley is going to be smaller.

On a 4.6 3V stage 2 has the GT500 fuel system upgrade (stage 1 only has Kenne Bell Boost-A-Pump), 3.25" pulley (stage 1 has 3.50" pulley), and longer serpentine belt (11 to 13 psi depending on RPM & elevation vs 7 to 11.5 psi for stage 1).
Stage 1 gets you 465-470rwhp & 435-440rwtq which is OK for a stock short block with a good tune and well-controlled IATs. Stage 2 gets you into riskier territory on a stock short block. At the very least you'd be well advised to swap in forged rods (Boss 302 rods were carried over to Gen 2/3 Coyote and are inexpensive) and 2618 alloy forged pistons. The short block would then be good for at least 700 crank hp (600rwhp).

Good stuff to know. Would you agree it’s better to go with a built motor vs stock motor for long term reliability and peace of mind reasons?

If so, where would you get a built motor from?
