Yup, installed the magnuson, pinned the crank (bought a cheap 90 degree air drill from harbor freight) and fuel pump (bought the hat ring removal tool which makes it sooo much easire) myself, although I did have a friend help me position the supercharger on top of the engine (can be done with a cherry picker). The install can be done over a weekend (mine took a week because I was not sent the shorter IAT sensor) and on the 5.7 there is no need to remove the front clip to install the intercooler radiator (I did have to drill into one of the air deflectors to run one of the coolant holes). Compared to a cam and header install, it is a piece of cake and it gives you ~20HP per psi with 8psi being safe limit on a stock 5.7. Kit cost $7800 with tuner, PCM and API fuel pump (~$49/HP) but you can get it cheaper now with all the end of year deals. Although I would wait for the bigger 2650 maggie instead of getting the 2300. Or you can go with the Edelbrock but not sure how they are handling the increased fuel requirement? I am now in the process of installing long tube headers (2 inch primaries) from stainless works because the cast manifolds are restrictive. Fuel mileage does drop by ~2-3MPG but it's because I am always droppin the hammer, oh and I run 93. But for me it is all about the SPG (smiles per gallon).I have SRT headers, exhaust and hellcat air intake. I don't have a drag strip around here so mostly daily driven with more power.. I haven't seen alot of 15+ 5.7 supercharged!! Did you install yourself?
Thanks for the catch, typo corrected. I would like to see any other mod get you 160hp without breaking the bank. Don't get me wrong $7800 is a lot of coin to most (myself included) but the prices I have seen for strokers getting near those HP figures is significantly more. A while back I posted some $/hp assuming all labor was performed by the DIY'er. But if I had a chance to do it all over today, I probably would have bought a used manual Hellcat. But since I am already in the rabbit hole and I love to wrench...what the hell.I hope/suspect you meant ~20hp per psi and not ~2hp!
16hp for $7800 is not a great deal.
160hp isn’t bad.
You probably get this a lot but are the new magnuson TVS2650 available?unfortunately we sold out this morning but we have 10 more kits coming, basic Magnuson kit is on sale for $6595.00 + free ship, for 8 psi, add 99.00 for the pulley, 569.00 for fuel system and 425 additional for tuning.....be glad to assist

only about 12 times a day, no, and now mid to late January for the Hellcat version and probably a month later for the 6.4 versionYou probably get this a lot but are the new magnuson TVS2650 available?
I have heard of people going to 10-11PSI on stock but with water/meth and they tuned for it (also was told by Wyatt at Arrington this was done on some customer builds with no issues but that they must religiously monitor their water/meth tank). But honestly, this is a discussion you should have with the place you are getting the kit & tune from.I have a question. Do you think I can get away going 9psi at altitude in my challenger? Its a stock motor and I know I should be at 8psi, but I lose so much horse power in Denver because of the altitude. I have a 2015 challenger R/T whipple supercharger. I’m using 3.50 pulley and I want to go to a 3.375.
