Thanks to Red_Cat and our runs this week at the ECTA 1 mile race in Arkansas, I am now regretting my 3.09 gears. He is running a stock 17’ Hellcat with driver seat and a few other items removed for weight. I am running a stock 19 redeye at full weight. He beat me and my son at the full mile by about 2 mph every run. We had better 1/2 mile speeds. We shift into 7th fear at about 160 and slow down. He carries thru in 6th. I think I will change to 2.62 and see if that helps. Either way it was a great weekend of racing with great people. My personal best was 181.45. I would suggest anyone who wants to run the mile go to ECTA. Got as many runs as we wanted. It’s painfull to say we were slower but we were.

That's what I was thinking but I've heard it will fit now. Still confused
The only mile events I know are Maine, Arkansas, Texas and Colorado.
1/2 mile events are popping up more and more often, as they can be run on smaller regional airports, like these:

Another option to look into could be the land speed racing at El Mirage, depending on class safety requirements etc.

You know, I looked at some acceleration video I did, and it does not even look like the tach hit above 6100 rpm. Not sure why the Redeye peaks HP at 6300 rpm, but Dodge would use less than peak for a shift point, unless they try to keep closer to peak TQ at 4500.
I plan on taking my RE over to Johnny B. NASA runway event and runny the 2.5 miles,. Looking to join the 200 club and told my wife, power bump will happen if the car fails to hit at least 200 mph with 3.09 gears. Dodge never said exactly what combo the 203 RE top speed was reached with.
I will have my 200 club patch or die trying.
The tach just can’t keep up but it’s shifting where it should.
They fit.That's what I was thinking but I've heard it will fit now. Still confused
I believe that, I can't keep up with the tach when trying to paddle shift. I'm too bust avoiding dogs and small children when I accelerate.
Well, I have to agree,..If DS shop claims direct bolt in for these with NO modifications for 15+ Demon/Hellcat/SRT8 ,. then OEM would swap.
The Driveshaft Shop | DODGE 2015+ Demon / Hellcat / SRT8 1400HP Full Chromoly Level 5 Direct Bolt-In Axles - Dodge - Domestic Axles
Is there a specific Website I can go to, to read more information on this and the requirements? It sounds like fun.
Hellcat diffs are bolt in swaps with Redeye and Demon. The 41 spline confusion is on the shaft between the CV joints. The diff splines and hub splines are the same.
Hi Paul
This article has a good explanation of the differences we saw last year in aerodynamics and gearing - the widebody Hellcat has 16% more drag than a standard body, which offsets all the extra Redeye power at top speed - then it's down to gearing.

Did you change to a 2.62 gear or are you keeping the 3.09?

I kept the 3.09 but have done major mods including a new motor, heads, ported blower, e85 and many other things. I will be trying it out at the 1 1/2 mile race in New Mexico in February. Excited to see what it can do.
16% more drag for Widebody? No way!
The numbers posted in that article do not jive with what FCA has posted.
2020 FCA numbers, Hellcat CD is .384 and the Widebody is .398 so closer to 4%.
Frontal area is 26 sq ft for Hellcat and 26.8 sq ft for Widebody.

You are going to do well. I am sure you saw the post a week or two ago that said sixth gear held into the low 190's? What is your goal and guess?
I want to make sure I am over 200. Anything else is a bonus. Barth Tuning has it now getting it ready. I am looking forward to it no matter what it runs. The people running the race are good people. Should be a good time.
What was wrong with the original motor?
I hve owned and driven both the 2:62 and the 3:09--and there's NO WAY the 2:62 is a faster car on low or big end racing.. The car actually needs the 3:09 to pull through the torque curve. The upper end pull with the 3:09 is so much stronger..
So--DOdge would make an option for their product that would make it slower?? HAHAHA... no way..
Get the 3:09--you won't regret it! and if you have a HellCat with an M6, get the 3:90 diff--BIG improvement!
