Hello Everyone,

My car is modded with 2.85 upper, 10% lower, Methanol and I use c16 fuel for rollracing. Don't know how much HP it's making. I have racestar 17inch with M/T ET street R. Car is ok from a 100 roll I think, but I'm looking to go for a 2.75 pulley and E85, which will make it even harder to hook now from a 100.

I'm looking to get the racestar beadlock 15x10, and get bigger tyres + Getting SRT brake disc 4 pistons for the weight.
What else should I go for to have better traction in Roll racing? There are a lot of forums for the drag but didn't find much for roll.

Would appreciate your help. Thanks.

My car makes 1000whp and dead hooks a 60mph roll with a 315 50 17 et street r as long as it's above 60 degrees or so and tires are decently warm. If mine will, yours definitely will. I do have rear upper control arms, lower trailing arms, dirs brace and demon springs too. Not sure how much the suspension stuff is helping from a roll but I imagine it is at least somewhat

1k HP must be awesome in a Hellcat. Mine is stock and I'm pondering the idea of starting to mod it but there's always a concern. I have some local reputable mopar shops that I can work with. Since you have 1K HP, has your car been reliable with no issues at that much power?

I was out tonight playing with my big tune and my car hooks harder from a 60 roll with the stock nitto drag radials over my mickey thompson 315's. Both sets of tires are new. Not sure my hp but it was right around 23lbs boost tonight and running strong.

With big power cars, pedal discipline is key. With the best mods, you'll never be able to just stomp the gas and expect to have traction with a car with as light of a rear end as the Challengers and Chargers have. Not on the street anyway, and not on the strip either unless the VHT guy gives you a triple shot. And, by pedal discpline, I'm talking about a quick, smooth roll on to WOT. Not a sudden 100% WOT stomp. Such things work in low power cars like my C8 that has an engine pushing down on the drive wheels. With a modified Hellcat, you have to roll it on.

My progression has been
First 15k miles: stock
15-20k miles: catless mids, intake, 180 tstat and canned 93 diablo tune
20-40k miles: 2.65 upper, 9% lower, bap. 1300cc injectors,, e85 tune
40-43k miles (current): longtubes, fully ported blower, 100mm TB, dual fuel pumps

Car has been flawless and the majority of its life has been 900+ whp. That said, I've only been at 1k whp for 3k miles but so far, so good.

I tried 305 45 18 NTO5 R's and could not hook anything below 4th gear/70+ mph. 315 50 17 will dead hook as long as it's 3rd gear pulls & 50+mph

I cave man foot mine at 60mph in 3rd gear if conditions are good. If it's less than 60 degrees and tires/roads aren't very warm, I usually give it a half throttle stab to get the big girl on her heels, and then immediately WOT. Works well for colder temps or when tires aren't as fresh or other factors where traction is more limited.

I've found that the ideal method of launching, either from a dig or a roll is the same. If you lean forward a little and stab it to 50% or so, as soon as your head touches the headrest, you push quickly into WOT. There's physics at play with that method. When you get tossed back into the seat, that's basically when your suspension is at full compression. That's when you have the most bite, and the car can handle full power. Prior to that, you blow the tires off and, too long after, you'll induce wheel hop if too much power is applied during rebound.

Let me ask this and it may possibly be a dumb question but bear with me. Ever since you modded the car have you enjoyed it even more and have no regrets?

Also are you ever concerned about resale value down the road if you were to sell the car or is life too short too worry about that and it's worth every bit modding it?

It's a lot more fun, the power is so addictive and such a thrill. There is one down side though. With stock power, you can play in a lot more spots. With this much power you definitely have to be more selective on where you play and a drag radial is a necessity, not really an option. On the street you can go 60-120 as fast or faster than you can go 0-60 and you cover a lot of ground really freakin fast. What a rush though!

Where did you get your work done on your car? You must have had a good reputable shop and tuner to work on your car since your car has had no issues.

True Street in texas. I have been beyond pleased. Hard to believe I have this much power, this reliably

Very nice. I have one more question. I don't mean to sound like a noob but other than drag radials, a D.I.R.S differential brace, and UPR end links (to ensure fitment for my 17x10 MT street R's for the track) that I have... what other supporting mods would I need to look into if I were to get some extra HP from my stock Hellcat.

I'm sure it probably varies how far in power I'd go but let's say I'm looking to get 800 HP crank and 725 plus RWHP stage 1 package or even as far as 875 HP crank and 750 plus RWHP stage 2 package from a reputable shop that I know.

What other supporting mods would I need especially when tracking the car or is a D.I.R.S differential brace, drag radials, and UPR end links good enough?

Springs will help considerably with weight transfer.

Yeah, I assume they're helping a good bit. Looks like it's trying to pull the wheels off the ground at 60mph full throttle. My goal with this car was 4 second 60-130 times on the street with stock motor,, blower and trans and full interior. Now that it can do that, I'll be good.. for a while.. lol
