Nice but odd they didn’t run it to red line.

It's a good question, I'll ask Eric which I'm sure when they can catch up they will prob respond themselves with an answer. What does everyone think about the numbers this build made compared to the other systems?? I really didn't expect this high of numbers especially torque.***The power is more linear than I expected also, almost ( not really but don't know how else to explain it ) like a centrifugal.

On a side note, the car is running freaking amazing. I'm getting used to it and better at using the new power daily. It shows no mercy for the 10.5 Nitto out back without pedal modulation! Embarrassed a Scat owner yesterday, one of those that doesn't know anything about cars just thought it was faster than everything because it had a bigger motor....beautiful ride though and sounded great, but it was an 8 car length event, which apparently deflated his ego as he would no longer even speak to me, and he was the one talking smack to begin with.

Back to the car, it drives great..still has a very very light amount of light switch or hesitation right at 0 vacuum, but nothing obtrusive or obnoxious, and honestly barely noticeable for the most part. Being a speed density car I'm assuming this to be the norm. ***Hopefully someone will introduce an electronic bypass to completely obsolve this soon!!*** But I'm really happy with the outcome. 

Hitting Rockingham next month for test and tune 1/4 to see where it is. Would love to see mid 11s

I have the old eforce and just retuned it on Friday.
Mind you I have the 6.1 with a 3.2” pulley. It sounds like your drivability is about as good as your gonna get. There’s always a light switch affect but it should be pretty smooth and you’ll get used to it. Here’s my graph d9db218cf4393c4111a7e05465cacfa7.jpg

So you made 34 more hp and I made 13 more tq....i have a slightly larger blower, and slightly smaller motor. All things considering, in comparison makes since.

But they didn’t red line you. So you could be more then me or even the same

I would think if it would have made more with higher RPMs they would have done it and posted the numbers...I mean they would want to advertise the kit as much as possible especially if being a new product to the market. Not sure why it wouldn't make more hp higher in the tach..not enough head flow?

So this is what happens when you change from 22" wheels to 20", and don't correct the final drive ratio in the system. 

It's our mistake and we're pretty embarrassed, but it is what it is. 

As noted above, we had a bad injector on this build and had the car back to resolve. When we put it back on the dyno to validate, we also changed out the rear wheels to 20" rims so we had a good comparison to most of the other cars we do. What we didn't do was change the tire size in his vehicle's base data file, making the RPM appear lower. So, what we got is the graph in the post above, the final HP number didn't change of course, but the torque curve was skewed, stacking the TQ at the bottom of the run. 

I spoke with JJ on friday explaining what happened and he agreed to let me posted the corrected graph below.

Again, we're sorry for the mix up and appreciate the opportunity to clear this up...

Kids. Haha
Still good numbers for the money. So I guess you’d know first hand,,
How much hp is givin up by changing to 22”
I was actually thinking of dropping 22” on just the rear of my car to give it a more raked looked.
Will I be giving up a lot??

nice looking curves, hope you are happy JJ. I do think that HP curve needs a bra.:rolleyes: i'm going to have to dig up my dyno results out for the 6/7.7 lbs of original boost. Give me a few .....

 

got it,  upgrades were arrington heads and cam package, jba shorties, and the 6lb kit magnusom.. Made 481 rwhp and 494 tq. so you had a whopping 47 hp more,  and our Tq was exactly the same.

not sure why my car is giving such high tq numbers , with the hellcat block and only 10.5 lbs of boost i have more tq than a stock hellcat at 696 lbs, hellcat reported to be 650 lbs.

 

 yes Kevin i already discussed meeting JJ at rockingham, and he is welcome to the dr's and even the skinnies if he wants to do 4 tire change.

 i'm thinking he will be around 11.6/11.7 depending on da and track prep.

Thanks Eric for explaining the dyno info, really appreciate that. I want those interested in the 2650 to see what it'll actually do for them and definitely want to see how it stacks up to the current systems available. **It did sound better with that massive amount of torque!! lol  But the car is quick and really fun so I'm happy and of course it's only a matter of time before more is done to up the ante..I'm actually super excited to see what this kit will do when the boost is turned up on a good bottom end! 

Just got back from WV with the car. It did flawlessly up and back! A real pleasure to drive. So the Rock will be an easy trip!

Greg I'm going to get the final date locked in for Rockingham, hoping you can make it...so far we will have a HellCat and a ZL1 coming with us! Thank you for helping out with the DRs and showing me the ropes getting these Challengers down the 1/4! And again thank you to Eric and the A2 Speed crew!!!

I know the 22s give up a lot...but damn they looks so good on there! Fills in the fenders without lowering the car. But I'm prob going to eventually trade these off if I can find a set of 20 x 10s or 10.5 like the current staggered 22s ( 22 x 9 front 22 x 10.5 rears ) ***You would be surprised actually how well the car hooks up with the Nitto 10.5 rears...I'm actually really impressed...best 0-60 3:45 secs

11:6s would tickle me fancy!!!
