HRT Stage 2 Cam Dyno

[@richey1794]

Just wanted to say thank you for introducing me to Chris. He definitely knows what he's doing as he helped me tune my Dodge Charger SRT8 after the same hrt stage 2 cam installation. Your videos inspired me to take on this job alone. Took me 2 months, but finally done last night after Chris did his magic via an email tune as I am in Ontario. If you're ever here, drinks are on me. Cheers!

I'm so glad to hear that your car is behaving a lot better after the dyno tune! Once that flattened-curve is figured out, you're looking at at least 420 wheel. Taking my car to a dyno tuner this weekend. I don't have enough patience for remote tuning 🤣

[@weaselsmopar6843]

Very Nice results that shelf I believe is the limitation of the intake manitfold. Mine did the same thing it would just go flat in the higher rpm's then I switched to the 6.4 ported intake and I threw down 479HP and 400 Torque.I am also running a 270 cam in a 2011 Charger R/T.

[@TrackPackRT]

Great numbers man! A lot of people love the 6.4 intake on the 5.7. I'm still not 100% if it'll fit on a 2009, but I've got my eye on it. First thing though is throwing the phase lock in. Then I'll dyno and see what kind of change we see in the numbers. After that I'll look at what else I want to do. Gotta try one thing at a time, you know, for science! haha

You were right about finding a rear axle, I ended up getting mine out of a wrecked 09 6-speed car. Cuz when I went to get one at the dealership they said they had switched them all over to the same axle the charger took or the Magnum which was a little bit smaller in diameter.

Did you end up going with the drive shaft shop race axles?

[@cortstahl6043]

No it's the time I was just trying to get the car back on the road and the guy up in Chicago had a wrecked 2009 which is the same year as mine so I bought the axle he ended up sending pretty much everything on the passenger rear, it was the axle the five-point aluminum knuckle it was pretty much everything except the rotor which I didn't think was a bad deal for $150.

[@alexanderhernandez1711]

Love the video man 🔥. I also had a question. I’m planning to cam my 2005 ram 5.7 and can’t decide which came to get. Either hrt stage 2 or stage 3. What do you suggest. It’s not a work truck want it more for racing but still drivable in the streets.

[@TrackPackRT]

When I called comp cams to ask about differences in their kits, they said the stage 3 kit was more for race applications, so I went with the stage 2 cam. The difference in advertised horsepower is negligible between the 2 kits but the stage 2 is more street able. In a ram it would be great because you’d have so much room to do the install!

I know it's probably not something you wanna tear back into, but COMP Cams does have a HEMI phaser lockout plug if you want to lockout your phaser so that there's no chance of piston to valve interference.

Hey man after the cam install were you pulling any codes and having stalling issues?

[@TrackPackRT]

The only code I threw was after I tore it back apart to swap out the phase limiter for a phase lock, I accidentally mistimed it by one link. That threw a code that gave me a hint that I messed up. Other than that no codes and no stalling, but my tune is really good. Is your car auto or manual.

At a point during the tune your tuner shut the vvt off. Is keeping it off permanently without installing phaser lock a option, or not?

Yes you can keep it shut off in the tune absolutely.

@@canceledczech457 No difference in 5.7L heads cast in 2017. The 5.7L HEMI has remained 100% unchained since 2009. And I mean that very literally. It's exactly the same, down to ever nut and bolt as it was in 2009 with the new "Eagle" redesign. As they sit, the 2009+ Eagle heads flow 331cfm intake, 181cfm exhaust. That's as good or better than ported LS heads. To give you an even clearer reference point, the 6.4L "Apache" heads flow only 8cfm more on the intake side, at 339cfm. However where the Apache heads off the 6.4L really shine, is the exhaust ports, which flow at 240cfm versus the Eagle's 181cfm. If anything, all I would personally do to a set of Eagle heads is port and polish the exhaust ports as big and as shiny as I could reasonably get them.

[@TrackPackRT]

Dresdon Acacin that seems like a hell of a setup that should fly when you’ve got it up and running! If everything is by email your data logging will be key. It also might take quite a few revisions to get it running properly as it seems like all the guys who got their stage 2 cams email tuned were having problems getting their cars running right. The biggest thing I can say is if they’re having problems with the car actually imputing the volumetric efficiency they’re asking for and for some reason it’s not responding, turn off the VVT and it will let you make the changes. That’s the one issue we had but that might only be an 09-10 specific problem.

[@DresdonAcacinTheOriginal]

@@TrackPackRT Thanks; I see, Ill keep that in mind. The master kit also came with a cam phaser limiter lock so Im hoping that helps with the power cap you ran into in this video.

Hey brotha, gathering parts for my 2012 5.7 in my Wk2. Got a 6.1 mani and a few things so far. My biggest question, for a 2012 vvt, should I go with a lock or a limiter? Gonna run the same stage 2 cam as you as I’ve seen impressive numbers and my tuner is experienced with it. Just not sure how to approach the timing issue and would like to avoid pulling the timing cover off again to swap limiter to lock. Got Kooks long tubes tuned it only so far. Wanting more.

[@TrackPackRT]

I wish I could say absolutely for sure a lock is the way but I haven’t installed mine yet. I’m going to try to get into it maybe this weekend if I can. Then back to the dyno to see if that was the big difference maker or not. I can say this, you’ll love the cam!

[@evanlaman]

I imagine my tuner will let me know whether to lock or limit? I have had a good experience with Johan (diablotoona). Gonna try to get her running decent the email route and then pursue a dyno tune somewhere

[@evanlaman]

@@TrackPackRT sweet man. I have time to gather things as I’m doing my install closer towards the holidays. Please share with us how the dyno sesh goes with the lock. I would be nervous running a lock and loosing the safety of cam timing. I’m just assuming a locked setup would loose the safety net of vvt to prevent a piston - valve collision lol

[@SuperAces101]

Can I use the 91 octane tune with the cam atleast until I get an appointment with my tuner

[@SuperAces101]

I guess I should've mentioned that I just installed the same cam you did but on a hemi 2015 same mods and everything

[@TrackPackRT]

@@SuperAces101 I suppose you could but it still likely won’t run the best until you get it dialed in with your tuner. I don’t know if a 91 canned tune would benefit you over the stock one while you try to get it to your tuner. The big thing is to make sure your AF doesn’t go to lean if you have a gauge to check it. If not take it real easy on it, I mean you have to break in your cam anyway, and baby it until you meet with your tuner. It might stall on you especially if you have an automatic just a heads up.

[@SuperAces101]

@@TrackPackRT ok sounds good and thank you for the feedback I didn't know when you were going to be able to respond, I think when I get back to my car I'll just reinstall the same tune and see if there's a better difference and like you said I'll just baby the car until then, the biggest issue I'm running into is the tuners are either super expensive or not responding so I'm trying to reach out everywhere I can

Hey man, really need your help. Love your channel, i am a subscriber. We talked briefly a while ago about your phase limiter issue. Update: I obtained all my gaskets etc for my cam install. I also just put a innovate wideband in my kooks midpipe with a badass gauge in my pillar. I found some hellcat lifters for 350 for 4 racks of them. Right now I’m stuck between a comp 270 or the stage 2 hrt for my 5.7 in Jeep wk2. I’m tempted to buy the stage 2 comp kit, I like that it has the springs and the rods with it in the kit eliminating the guess work. Did you buy the kit that came with the comp lifters or did you run mopar lifters? Non MDS or hellcats? And as far as gaskets go, I bought cometic head gaskets and fresh cometics for my headers, also got a new intake manifold gasket for a 6.1 as I’m slapping on a 6.1 mani i obtained for my cam install (purely for looks). Also, did you use stock fasteners? I could go with the more expensive ARP bolts but it seems like overkill for a NA 5.7... I’m trying to cut cost if possible, but am willing to pay extra for hardware etc if it’s worth the peace of mind. I also have decided to just lock the phaser and not mess with vvt. I think it will make it simpler to tune and less problematic. I’m limited by the auto RFE trans, so reverse, stopping, and idle could be problematic initially although I’m prepared for that. My main questions are: 1. Did you use the comp kit and their springs and pushrods, 2. what lifters did you use, 3 and what hardware and gaskets did you go with? 4 were you able to reuse anything, I’m planning on not getting a new timing chain & cam sprocket. Also thinking about reusing the valve cover bolts and gasket - do you advise this? Your videos are extremely helpful and will be referenced frequently during my own install. I saw you were able to reuse some stock bolts etc, can you elaborate on this. My Instagram is Hemi_Rx if you want to check out my build. Feel free to pm me there or comment back here. Any and all info you provide me will be HUGELY APPRECIATED. Mopar Fam!

1. I used the springs and pushrods that came with the stage 2 kit 2. I used 5.7 lifters 3. I used new factory head bolts, re-used the valve cover bolts 4.

Do you mean the lifters? We did put in new lifters. My car didn’t have mds so we could’ve gotten away with not changing them, but I didn’t want the old wear patten from the old lifters wearing into the new cam so we just changed them as well.

Track Pack R/T thank you so much for the info really helps me barely new into the performance🙏🏻

[@TrackPackRT]

Alexander Hernandez no problem, if you need help just fire me a comment. If you have mds lifters (if your car is a 2009+ automatic that’s not a 6.1 Hemi it would have mds) you’ll need to change the lifters to non mds lifters for a lot of these aftermarket cams. If you didn’t want to change lifters and keep mds you could go with the stock 6.4 cam which makes decent power in a 5.7.

Yea it's definitely a little on the unrealistic side. Say I do replace the phase limiter with a phase lock and that was the restriction responsible for the flat spot. Say I end up with 430 whp next time I go in. That would give me 56 whp. They were claiming 83, likely on an engine dyno, so lets factor in a 15% drivetrain loss for comparison sake which means we should expect to see around a 70 whp gain.

Ported 6.1 hemi manifold and some plenum spacers. Just the plenum spacers going to drop the iat and a ported mani 20-30 hp. Look at omgmrmacks instagram its a hidden hemi mod

Was he getting 20-30 wheel hp from that? That sounds kind of insane if he is.

Are you talking about the sikki gaskets?

Absolutely. Dyno tune is a must folks.

[@fadedxmist7102]

V.V.T would add more horsepower to that wouldn't it

[@TrackPackRT]

VVT would give you a more power through out the rpm band (a flatter looking curve) but not necessarily more power. The problem is with bigger cams is it interferes with VVT which is why you have to install either a limiter or a lock depending on the specs of your setup.

@@TrackPackRT ahhh ok thanks. Yeah I have a 2016 300s 5.7 and I have a stage 2 VVT comp cam sitting in the living room. Just waiting for Christmas to be over with so I can but my exhaust system with it

Vvt can just go it always seems to be in the way.

What exactly is it? I’m not knowledgeable on it.

[@TrackPackRT]

@@sokodad Variable Valve Timing.

[@Sak-zo1ui]

sokodad as track pack rt said, variable valve timing. It allows the valve timing to change throughout the power band or in different temperatures. On the 5.7 and 6.4 the idea is to save fuel in the low end of the rev range and to maximize power in the top end of the rev range but to also to save fuel.

[@sokodad]

Sak 20012019 also had a question about the mts or whatever they call it that the automatics have?

[@brokelahomachickenfry6497]

Did you raise your rev limiter?

[@TrackPackRT]

Yes, it revs to around 6k now.

[@brokelahomachickenfry6497]

@@TrackPackRT I think mine is around 6200rpm now. I had it retuned a little. It is doing pretty good without surging like it was but, now I have been having that dying at a stop on drive thing again. Have to take it back next Saturday. Do you plan to do the 6.4 intake manifold with the msd box?

[@TrackPackRT]

@@brokelahomachickenfry6497 glad to hear you have it back. The automatics really seem to have a hard time with coming back down to idle. I’m thinking about my intake options. I had a couple people tell me a 6.4 wouldn’t fit on an 09, but I haven’t done enough digging myself to see if that’s actually the case. Also might send my 5.7 intake to get ported. There’s a few options on the table

[@brokelahomachickenfry6497]

@@TrackPackRT that or the 6.1 intake. Uses the same cai. Maybe have the 6.1 ported.
