3 Hellcat Mods to Make Over 100whp More Than Stock!!!

With just 3 mods we were able to make more than 100whp over what a stock Hellcat makes on our Mustang Dyno. What were these mods? Metco Upper Pulley, Texas Speed 2" Longtube Headers, and a JLT Intake. A stock hellcat makes around 560-580whp on our dyno. This one is leaving making 707whp and 709wtq!! Now that is some power!!!

Thank you!

[@behnamzamani5907]

Ok nice buddy it said sd Iam in San Diego ca hard to find mopar good techs out here

[@StrideX21]

And i thought my zl1 was fast. I ran 11.4 quarter mile in my bone stock zl1 but this guy ran a 9.8 in his red eye and all he has was a tune for e85 and my jaw dropped, these hellcats when done right are STUPID. Get a couple mods and an actual tire setup and theyre a problem

[@sdracingllc1594]

They do very well with simple modifications and proper tuning

[@stevenbabinski7635]

Jesus. That's bad ass

[@sdracingllc1594]

Thank you!

[@Bulls_of_steel]

Nice vid. 👍 What size pulley did you use?

[@sdracingllc1594]

2.85" Upper

[@ReidPerformance]

Went to a 2.85 pulley and you were able to keep the factory injectors and pump?

[@ronn147]

Damn that’s nice! So this is on stock injectors and stock fuel pump? If so could you do just a 2.85 upper? And do you know what kind of power they would be around?

[@sdracingllc1594]

Yes this is with all the factory fuel system. This is using a 2.85 upper pulley. If just doing the pulley it would be 650-670.

[@6.2_zeus]

I guess it depends a lot on weather and elevation because my hellcat stock did over 640whp no mods. With full exhaust and intake I made over 700whp. I’m in SoCal. Was about 60 degrees the day off dyno.

[@sdracingllc1594]

If you take a look at the description we explain that the hellcats are between 560-580whp stock on our dyno.

[@navypackman]

At sea level, a few years ago, my 2017 Hellcat Challenger A8 made 653.9 to the ground. EXACTLY 7.5% drivetrain loss, and my girl was the weakest stock car that day. I'm about to get my 2022 Redeye Challenger dynoed. Same shop but definitely cooler time of year. Wicked cars!

[@yoeurmuther8807]

Depends a lot on the dyno you use. Mustangs are notoriously ego-checks bc they tend to read a little lower than other dynos, which may or may not be more accurate but regardless you should orob go to another tuner lol

[@NGL-pt4do]

Yea I’m in south Florida and my bone stock hellcat made 645 whp(not a mustang dyno).

[@billiondollardan]

Part of me wants to do this to my Hellcat, but I daily drive it and a full tank only gets me like 220 miles now. 100 hp more and I'd probably be at 180. It's a quarter tank to go to work and back every day

[@sdracingllc1594]

Adding the power want decrease your fuel range anymore than it already is.... your right foot will though ;)

[@behnamzamani5907]

Hey buddy I see it say sd racing are in San Diego ca byy chance??

[@sdracingllc1594]

We are located in Greenville SC

[@SqubbaSteve]

I want some more power in my TRX. Do you recommend these mods for it?

[@sdracingllc1594]

Yes

[@ogtimmy2355]

Do you need an unlocked PCM and a custom tune to do this?

[@sdracingllc1594]

Yes you would.

[@christhegreatgrow8002]

Where are you guys located? Can you install same upgrades on my 2017 challenger hellcat?

[@sdracingllc1594]

Greenville SC and we certainly can.

[@jawjackin6513]

​@@sdracingllc1594I'd like to get some more from you guys! How do i get in touch?? I'll come to South Carolina

[@Tfromthecity]

so how much ovr hp are you making would you say ik stock is 707 also do you think with this exact setup you could run a redeye?

[@sdracingllc1594]

707 is to the crank, not the tire. The results of this car would be 813 to the crank.

[@Tfromthecity]

@@sdracingllc1594what numbers do you think i could make with a legmaker intake and a 3.17 upper so i dont have to tune it and void warranty

[@rogertorres6752]

​@sdracingllc1594 what would 826whp be to the crank

[@HellcatM6]

mod 1 , get an awesome haircut- easy 50 hp

[@SRTKOVA]

Mod 2: red seats , gives you a good 500 horsepower

[@got2luvjj]

Where can order those parts?

[@sdracingllc1594]

@@Tfromthecity the parts used are in the comments of the video, also said what they are in the video. We don't have parts sales on our website, that is done via email, phone call, or in store purchase. If you want to purchase them from a website... they aren't that difficult to find since again.... we listed the brand and the specific parts that were used. Our clients.... prefer to deal with us directly rather than be a faceless website order.
