There's a huge thread on here about them. Read it and make up your own conclusions.Anybody on the forum install one of these without a tune? Any problems? Approximate boost gain? Elevation?
Its seams like some people had to try this???
Are you going to be running 91 or 93 octane fuel? I have found a decent amount of info with people running 93 and it seems to have good results. I've been waiting for someone to show some results with 91. Steve says the 707 Hellcats do fine on 91 but I'm afraid it will knock severely and pull enough timing to make any gains from the pulley diminish.I have one on order with a performance shop down here, should be here this week or next. From the shop and research I've done, I've heard good things. Unfortunately, they have not done it to a car that this was the only mod and therefore have no baseline vs install numbers. I am looking to dyno before and after but not sure if it's going to happen. If it does, I would happily show some results. I have been unable to get a track as of yet with the hellcat, bought it last month (2018, 10k miles). I would love to get some pulls of it on radials only then radials with the package that includes an intake and incognito. Will keep the thread posted.
Very interested, please share what your results!I have one on order with a performance shop down here, should be here this week or next. From the shop and research I've done, I've heard good things.

Modifying stock boost #s without a tune to let the computer know it's coming usually results in other things happening ie timing or dumping fuel. If you can point me to something that shows a 1/4 mile pass or 1/8th mile hit, I'll read it.
Have you tried running a bottle of Boostane shot. It's the 4oz bottle that you add to each tank of fuel. Steve told me this would really help cars on 91 and it won't hurt anything since it's a small amount. He said it would put the octane right at 93. He recommended for best results to add the Boostane and a gallon of E85.
Watch this Youtube video, he does passes before and after this pulley with similar prep & da. He picks up MPH and is consistent about it.
This second video is a stock Trackhawk on a stock tune with only Incognito & intake putting down 724AWHP.
I've got the incognito pulley on my car and did a pre-dyno with only intake and did a post dyno with the intake and incognito, on 91 octane I picked up 35whp. I know timing was being pulled because of fuel quality, we added a gallon of E85 on the stock tune and brought it up to 51whp gain.
This is a good pulley setup to run for a stock car.
If you are mixing fuels to cover up the knock you are band-aiding the issue, and the issue is that adding boost requires reworking the timing tables to be consistent and effective.
This all seems crazy to me. I want more power but I don't want to tune my car, but I'll mix a gallon of E85 and some octane booster every time I fill up my car....no thanks
I cant decide if this is worse or the flex fuel thing that also, doesn't control timing.
AFR keeps the motor happy and safe.
Timing is where you find power.
I installed one of these on my 15 HC and went from 8lbs to 10# and definitely made a difference.Anybody on the forum install one of these without a tune? Any problems? Approximate boost gain? Elevation?

I will be running 93, I have never put 91 in the cat or scat for that matter. Have not forgotten to update thread, just waiting for the JLT intake as its on back order to install the incognito.Are you going to be running 91 or 93 octane fuel?
