On a purely practical level, it's sort of a waste of time and money to mod your car, unless you have the disposable income and you're just having fun with it. Although, you could argue that you're making the car even more bulletproof and long-lasting by modding it with upgraded, tougher parts 😁 at least, that's what I tell the girlfriend 🤷‍♂️

That is awesome man. No I get it completely, tons of people saying don’t do this because it’s a waste of time and that may be for them but not for another. What I do like is when people give objective advise such as one part over another and the whys. That’s good stuff. Good luck on your build
Objectivity is something this world sorely lacks in 2020! Thanks! Would you mind PMing me the info you brought up earlier in this thread? I’m curious about what you went through.

Absolutely and I’m straight up with my wife she just says, “yikes” and moves about her day. I’m at the point in my life where I understand money is something that you can’t take with you. You work hard for it so spend it on something that brings you joy in your life.

I had great luck with a Jay Greene Cam. Awesome customer service and an all around great guy. Long tubes, cam+springs, phaser locker, and dyno tune my M6 Scat Pack put down a conservative 484 HP and 463 TQ on 93 pump gas. I have it set up for drivability since it is a daily driver and didn't chase numbers. I max HP at 6.25k RPMs. I do have some ignition timing pulled when the active runner engages in the intake manifold, so I am considering going E85 to neutralize this. Sunoco GT260 (100 Octane) helps significantly, but even then, I still have a tiny amount pulled. This car is an absolute monster on the freeway, especially from 3rd to 4th gear, 40-120 mph.

That sounds pretty awesome. Did you do anything to or replace your intake manifold?

Fantastic, thanks for your input! Good to see there are members who have done these swaps and achieved good results.

Honestly, most of the off-the-shelf cams just aren't that big compared to the factory cam.

I'd probably go with Comp Cams stage 2, but I already have an MMX NSR cam here, so no point in switching it up if I ever get around to this.

It looks like MOST of the choices are going to net you around 480whp IF IT IS TUNED PROPERLY.

Getting the proper tune is going to matter like 5x more than which of the shelf cams you pick.

Nothing with the Intake Manifold. I was going to port it, but haven't done it yet.

That's what it's sounding like. I've seen MMX's max effort cams make 500-520 wheel, which is pretty great, but I wonder how much if any bottom end torque is lost there, what they're doing in the tune, street manners and drivability, etc.

Im curious of the same thing. Mine is not a daily driver but I don’t drive it like I stole it when I’m in it either, at least not all the time. So I’d like comfortable drivability while having a little more get up and go for when I decide to hit the track as I’m looking to get into the 12’s N/A. I need the 0-120, I’m never going to go 150 or 180 in the thing. God knows the last thing this car needs is more low end torque, smoothing that out a bit would be ideal.

Lol, the low end torque is fun but it can easily overwhelm even 275's on the back, it needs at least 305's. Especially with how aggressive the first couple gears are in the A8 trans.

Our 392's should be able to do 12's from the factory. But if you have the M6 it may be harder to do.

It’s fun but leaving a stop sign and barely tapping the gas and having your head go back is hilariously too much lol, my wife thinks I do it on purpose. I’m like, I don’t, I swear, it’s just hard to have the right feel.

I’ll never see 12’s stock man, never. Colorado is a poo hole for many reasons and altitude is one of them. 13.6 on 245’s is my best, albeit I’ve only done 3 runs in the car and in my life lol. So for me to see 12’s at 5700’ I’m going to need some damn good air and some bolt-ons and at least 275 tires. I’d prefer not to change the rims, I really like them.

Gotcha. Yeah that DA is never going to be friendly to you unfortunately. Forced air might actually work better up there.

I like those rims too but you really need wider rims and tires to hook better. They make Hellcat replica rims at least

Beautiful thing with a custom cam is you won’t lose Torque down low. If anything, you’ll gain around 10 ft lbs below 3k RPM. You’ll also gain 20-30 ft lbs TQ around 4K RPM. I think the drastic increase in torque in the middle RPM range makes people feel they lost torque down low through their butt Dyno.

You might have a point, but some guys do put in way too big of a cam that does take too much power from down low and moves it up high.

Yeah, but I don’t want that headache. Everyone I’ve ever known who has supercharged or turboed anything just has issues. If I wanted that much power I would just trade the car in for a used Hellcat and be done with it.

I’ll think about the rims, I wanted to see what 275’s did for me first. If I can get to 12’s without changing rims, that would be ideal.

Fair. And 9 inch rims may be a tad small for 275's, the contact patch won't be fully engaged.

Lol seriously? If I try to buy rims my wife might murder me. 😂

Have you priced a cam swap and a tune? Are you capable of doing the work yourself?
