Just for fun....From all you GURU's out there, in 2022, what INOVATIVE POWER modifications for the Hemi 5.7 will be the talk of the forums?
Is there anything new on the horizon, that will get our juices flowing?...What is your favourite power mod?

nitrous oxide will get your juices flowing! :party36:
its the gas of the future haha!
suprisingly a quick search of Amazon reveals an impressive amount of nitrous oxide for sale! oh wait those are whip its :roflsquared:

Little tidbit for you Nitrous isn't new,lol.The Japanese started using it in WW2 on their little plywood fighter planes,and Mike/NOS started putting kits out for automotive use way back in 78,i've been running nitrous toys since 81,lol.This toy was swallowing nitrous in 81,lol

Well there is a way to inject liquid oxygen directly into your combustion chambers to make more power but we can't talk about it because it's a religious topic and people lose their minds

Pray tell us how,unless you're referring to nitro methane,which is an oxygen bearing fuel, that keeps making power the more you inject it,until you have a bomb,lol.Dodges Ramcharger engineers experimented with pure oxygen in the 50's but never had great success with it.If you've got a way to inject pure oxygen and keep an engine from turning into an explosion waiting for a place to happen please clue us in,i usually try to stay semi-up to date on things,but this one is new to me,lol

Like I said, it's a religious topic. Whatever anybody was told by their grandpa in 1976 is the gospel they will cling to until the day they die so we can't talk objectively about it.

I see whipple finally came out with the 3.0 SC. On their site, they sell it for all the other 5.7 vehicles except the ram lol. They brought back the ability to buy the 2.9 for the ram. Interesting.

Cheaper to drop in a brand new 6.4 SRT motor right from the dealer,and it has a 3 year warrenty.You don't know what you're up against with a boosted 5.7,just say they aren't the most reliable engine when boosted,unless you build the bottem end of the motor.You can buy a brand new complete 6.4 non-mds SRT engine for probably still under 12,000 Canuck (last one i got for Brandon W set him back just over 10G,but there's probably been a price increase since then),then sell you're 5.7,and the parts off the 6.4 you don't need,like the clutch/intake manifold etc,to recoup some of your investment. You end up with 485 hp and 470 lb-ft with a 3 year warrenty,and it's reliable.

I think I could be satisfied if I could get 40 hp more without spending an absolute fortune,imo, for true duals/ Lt headers and the like.I don't believe in aftermarket fake cai and a larger throttle body or the spacer. But this is why I like my 77 Chevy truck for mods better.Also in a truck my 5.7 is adequate actually as it is.But sometimes I think I'm a recycled teenager or something.

You have a valid arguement Wild One. Food for thought...I love to research things..now a new project !...thanks eh!

If you deal with an Alberta dealer,you beat the 7% provincial sales tax Dave,lol. By selling your old 5.7 and the pieces off the 6.4 you don't need,you should recoup a few thousand on the deal,there's nothing you're going to sell off the 5.7 if you boost it,other then maybe an intake,and 5.7 truck intakes aren't worth much,lol

Hemi 5.7
The elephant in the room when talking about power is that all the low hanging fruit's been scooped up by the manufacturer already. The same tricks that make power also improve volumetric efficiency and therefore fuel efficiency, they have everything to gain from maximizing that. It doesn't cost a penny more to make the air intake larger, variable cam timing + variable intake runners means they can run a huge wide open head and still deliver good low rpm driveability and emissions, modern manufacturing has even made cast log exhaust manifolds better than they ever have been, throttle-by-wire allows a large throttle body that's not jerky off-idle like the old days.. they didn't really leave much on the table.

So if you compare the torque a 5.7L Hemi makes (410 lb-ft) vs. the highest powered naturally aspirated engine ever put in a production car - 2023 Corvette's 5.5L engine only makes 12% more torque. Adjusted for displacement that's 16%. The 'vette's engine revs higher of course but at RPM's that both engines cover, all else equal the stock Ram Hemi is only 16% behind the most bad-ass NA production engine ever and it takes four camshafts, individually CNC'd heads (not as-cast like volume heads) and all sorts of cutting edge race tech to get it there.

Short of boost or sauce, how much room do you really think there is for DIY improvement?

My other car is a 94 Mustang 5.0 rated from the factory 215 horsepower. There's probably 100 horsepower worth of low hanging fruit sitting there in the heads, intake manifold and camshaft... but that was close to 30 years ago. Nobody leaves that kind of power on the table anymore, there's not 100 horsepower hiding in a Hemi, in fact other than raising the rev limit I doubt there's 35 and most of that is probably hiding in the exhaust manifolds & mufflers.

Dodge claims the fastest naturally aspirated production car record yet with 11.70's for the 1320 Challengers.GM's 5.5 doesn't make any torque,it's a high rpm motor that makes decent horsepower with a s****load of rpm,and everybody knows horsepower is just a mathematical equation of torque X rpm,so the higher you rev it,the more horsepower it'll generate,but it still won't get across an intersection any faster,as it's torque hasn't increased,lol There's still lots in a N/A 6.4 by porting the heads/intake/cam/headers and more if you up the compression. You apparently haven't looked at a pair of peanut port stock 5.7 log manifolds have you.The factories in the 60's were building far better cast iron manifolds then Ram puts on the 5.7 and 6.4 trucks

I've put over 15k miles on my supercharger since acquiring the vehicle. I daily drive the truck so it's reliable. However it's the edlebrock not a Whipple. A lot of difference in boost pressure.

I'm currently working 156 miles from MMX and am planning a day off to go down there to check out their drop in hellcat engine similar to the venom ram.

My point your 13k comment, you can't take it with you and my low boost 5.7 might better fit my 11 that I use to tow and I could install a hellcat engine in my 14. I think Wild one is influencing my thought process.

Yeah, I've been drooling over the whipple for years and never pulled the trigger. It was hard to justify the price with guys having issues running the boost and having to sink more money into rebuilds. I'm currently having engine issues and it may go blooey at some point here in the near, or not as near future. Either way, I'm going to be ready to put a cammed 6.4 SRT long block from mmx in it. I'm not sure what the power difference would be from a whipple on a 5.7, but it'll certainly be more reliable with a new 6.4. Plus it'll sound all the more better with a cammed 6.4 and catless LTs mmmmmmmm

Challenger 1320 makes 475 lb-ft of torque with 6.4 liters, Chevy LT6 makes 460 lb-ft with 5.5 liters. That's 13% more torque per liter.
