How much WHP from 10% Lower on a Redeye? Forza Stage 2 Build Started!

2211 Views 22 Replies 6 Participants Last post by  Taxinator
Hey Gents,

So I ordered my Hellcat Redeye Charger last year and had the dealer install 3.09 Gears and Nittos - which compared to my old 707hp Hellcat with 2.62s...was definitely noticably faster.

However, regardless of what I had read on many threads, the 3.09 gears (when installed without a tune) create issues with the cars match-revving during downshifts and other small quirks with shifting.

So, I've decided to bite the bullet and get the tuned. While I'm at it, I'm doing a mild build.

The car will be receiving

  • ATI 10% OD Damper
  • ER14S plugs
  • Mashimoto 180 Degree Thermostat
  • Forza Tuned Stage 2 Tune- and TCM tune.
  • Gates Belt

Please spare me the time starting a discussion about voided warranties - as I don't give a shit- financially its not a worry and regardless - I'm sure the motor/trans can handle it just fine.

My questions -

Is anyone running a 10% lower on a Redeye? What type of boost should I expect? RWHP numbers? 1/4 Time on 18'' Mickey Thompson ET-Rs?

Forza is junk you’re paying for a name, pretty standard mod though. Make sure they pin the crank. If you’re paying for a “special package”, they should be able to tell you around what it’ll make. Don’t they tune it on a dyno? If not I wouldn’t even waste my money, regardless if I had it to spare

Forza is junk? Have your ever been to his shop? Ever seen or driven in the cars he works on? Seen his workmanship?

you probably won’t see a more professional, cleaner and higher attention to detail shop in the country .

Brentons a friend and I’ll bet he knows a **** more than you do about these platforms - especially considering his wait list is a year and half .
Yep, I know nothing. And obviously he doesn’t either if he can’t give you expected whp figures. They don’t do anything special that all other shops don’t do. You pay for the name and the cool badging
Relax, it’s Sunday. As you said, he’s your buddy, so I understand why you feel the way you do. Just saying they’re overpriced and you’re paying for it. Popularity doesn’t always mean best work/best value.
he said 100whp over stock on a Redeye . I wanted to see what other people were getting, but nice assumptions chap.

Love the patronizing tone too. Thanks for teaching me about business big guy.
That’s great! Have fun with the car! Should be fast!
If you’ve been to the shop there are cars there from Kuwait, UAE.

Most of the cars were Lambos, Ferraris , McClarens .
Yeah, lots of issues with people taking hellcats to shops that aren’t hellcat/Mopar experts.
Btw, Forza has nothing to
Bro you are a tool.
anyone who says bro usually is tbh
Might as well have Richard Rawlings at gas monkey garage do it if you’re trying to get a sticker on your car for where the work was done.

anyone with 1900 posts on a car forum in less than 9 months is usually someone without a woman worth f**king and a life worth living. I hope your enjoying that Hellcat on your 96 month payment plan buddy.
Wow I must have hit a nerve. Like I said good luck, car should be fast! 🤡
Following this thread for updates when/if you ever get this done at Forza. Hope your car doesn’t sit for a year and a half 🙃
