Almost six months since my C6Z stage 3. Have two problems, no traction in 1st and 2nd haha, my Michelin pilot sport as3 not the best for high hp applications either. My granddaughter just said “I forgot how fast your car is grandpa”. Love the results I got from the RPM crew. I always display my extra large laminated dyno and build sheet when showing. Get lots of compliments on the way the car looks and especially the way it sounds. Thanks again RPM!!

Garrett, what’s the harm in letting us hear the cam idle once in a while. Come on dude, everyone likes cam chop lol.

No one commenting on the weight loss gains of Fran. Damn, amazing results. Motivating to get my act together and do weight reduction!! Lol.

Garrett you really showed just how much you know about working on cars in this one

400hp VW owner here....hoping to graduate to a "big boy car" eventually Ideally a C6 either LS3 or 7. Obviously the Z06 is king C6 but I am ok with the LS3 cars after hearing cams in them....I told my wife I want to set car alarms off and "disturb the peace" with a corvette one day 🙏 Mods don't seem all that more expensive than for my VW. Got about $5k in the VW so far and not done yet. Should he a good warm-up for a real sports car.

I watch every video you guys make. I just bought an 08 Z with only 4000 miles and will be doing your stage 3 first thing next year. I would love to see you guys add at least a 10second clip of each car when it's finished just idling. I personally love what these cars sound cammed, the chopping is really the only reason I'm doing your stage 3 haha. So just throwing that idea out there. Maybe get you more business as well who knows Thanks guys. Look forward to meeting you all soon. I'm in NJ btw so I'll be driving up to drop off and to pick up.

What is the rod-mod? In OE configuration the intake manifold has an extremely sharp transition from the plenum to the top of the runners. Air hates sharp edges, and loves curves, so the rods give the air a nice radius to follow into the intake manifold. The porting (at least what we do at GPI) removes the stands from the middle of the manifold to increase plenum volume, cleans up any casting flash from the runners, and cleans up the throat by flush cutting the vacuum ports. Our ported rod-mod has been tested by many and proven to consistently gain somewhere around 10whp on a cammed 6.2, and make significant gains through the mid-range.

That’s a beautiful C6, love those wheels. 480whp in that thing sounds like a blast, great video.

That head unit thing is true 😂 when I got an aftermarket one my chime got louder and I thought I was crazy

My '08 Base Vette got a BTR Stage 2 cam/kit swap 4 years ago. It Dyno'd 451hp at the wheels. BTR claimed a 67hp gain, and I believe that's about what mine got with no other mods. Mine has NPP, for a little help.

Excellent numbers.

Yo Fran lost mad weight oh shit bro 💪🏿💪🏿💪🏿💪🏿 I didn't even recognize him 🔥💪🏿💪🏿💪🏿

Ls3 is my favorite motor

That be a fun car right there.

Wow on stock heads, this is a serious power!!

The LS3 intake with the rod mod performed AND fully ported typically picks up 6-8 to the wheels on a stock engine and 12-15+ on cammed setup. Supposedly worth it for the gains under the curve.

Get a Audiotec Fisher Helix DSP and that will make the sound system sound amazing and quiet the ding.

Do ls motors like being ran at 13+:1 afr? I thought 12.5 was the baseline number to go for

Wish you would have left the original intake on and did a Dyno pull then did the swap with Dyno pull after just to see if the intake is any good

Love to know the specs on this LS3 cam?

I'm torn between buying a low mileage C6 Grand Sport or a new car for the warranty, updated interior etc.. I love C6's but the older I get, the less I care about having a quick car, the more I care about a nice interior and just having enough power to have fun on the street without going to jail for taking 2nd or 3rd gear up to redline, lol.. if I do end up with a C6, I'll definitely have it shipped to you guys for the tune and mods etc.. I'm right down the road in Maryland. Were you the shop that used to be in Overlea/Rosedale, MD right off the highway or am I confusing you with a different RPM?

Just Curious if you will tune older F-Body's with the old LT1/LT4s with the Torqhead EFI that I believe is based off of the LS ECU's

Shoulda added heads!

Is that a banshee on the shelf?!

cam only...but also exhaust and intake?

Can I put a cam in my stock GS and it be fine or does it need to have other mods on it already like resurfacing the heads or milling and stuff ?

Bro they RTVed the full exhaust!? That is so wierd

Nice 👍

During the C6 years, what was the final drive or gear ratio or ratios from the factory?

You took 425 as I was typing it

If I call and ask to have work done on my 02' SS, am I gonna be turned away? I was told the last time I called RPM they don't do work on LS motors anymore...but this video contradicts that, or was the person I talked to wrong?

My cai and cam c6z made 527whp, for comparison. However I don't know what the stock dyno was, or if the previous owner even did one.

Well damn, it looks like there is a V2 wagon hanging out in the shop.

I hear from time to time Fran mention the car dont have a tire to get good traction.... what are the recommendations to resolve that? Brands? etc?

That’s one way to fix an exhaust leak 🤣

“Cam only” with ported mani,cold air and headers lol 🤔

Are these numbers at wheel

This car made more wheel hp baseline than my cammed ls3 😢

Its is not the best intake. Most aftermarket ones make more power just cost you $1000.

Why don't y'all ever do lifters?

C6 ls3 will make in the 450s with just bolt ons...with equal torque. Torque is the actual power of a engine.

First

Garrett you need to watch prior vids and learn. It would help so you dont keep getting the crap from the guys.

Don't close the f ing trunk like that
