Had a friend with a cam in his Gen 3 and it ran like a BEAST! I've got about 614 at the wheels in my Gen 4 and he stayed right with me.

With all due respect I would assume that your friend had ported heads to accompany that cam at a minimum. There is no way that a GenIII car is even remotely close to 600whp with just a cam swap.

With what the OP has plus a thiner head gasket and adjustable timing set you'd be knocking on the heels of a gen4...

I think you'd be surprised - My friend did not have ported heads and only bolt-on's! The cam in our Gen 4 is a huge limiting factor.

I have had two SRT-10 Rams, one of which I still have, I've also had a Gen III coupe so I am pretty familiar with the GenIII's. I've also watched Gen IV's put down an additional 80-90rwhp over a GenIII stock for stock, I think there were about 10-12 of us that hit the same dyno that day. I have yet to get my GenIV on a dyno but I can tell you it pulls way harder than my GenIII and my car is bone stock. It really comes down to the dyno and who is running that dyno. Talk to Todd at A&C, if someone knows the expectation from Vipers he's a good person to ask. I actually had a very good conversation with him a couple months back and he will be the first to tell you obtaining 600rwhp out of a NA GenIII is nowhere near as easy as everyone thinks.

Nothing was said about 600 WHP. It really dosent take much to make a Gen 3 run with a 4.

Seems as though you are looking for an argument.

You've been on the Vtcoa too much talking to that hack from Texas. V1R racing l0l.

600whp is easy to obtain on a Gen III but you have to have a set of ported heads in addition to a cam and bolt ons. There are several guys with 625-650+whp on h/c Gen III's. I will say that I've never seen a cam only Gen III come close to that. Dyno numbers are what they are. The most consistent stock Gen III pulls I've seen are 435-450whp. Occasionally you'll see some pull more (dyno's can also be manipulated) but I'd be willing to bet if you gave three bone stock Genn III's, that pulled 435, 450, and 460 on three different dynos, to someone to run at the track, they'd all run very close to the same time.

well thats good to hear.. i dyno at 480hp 507 tq on a mustang dyno.before cam. i would be happy with 515hp 530tq after cam swap on mustang dyno..also to add i just did a cam swap, no head or intake porting... so basically i changed out cam,lifters,springs and push rods.

What do you have done to your car as of now? 11.11@125.20 is a pretty good time, and 480HP on a Mustang Dyno is pretty high! I've been at Dyno days with the New England region and watched Viper after Viper not even put those numbers down and that was on a DynoJet. When I had my 06 coupe it only had a cat-back but I also only put down 442HP/460TQ, we were all reasonably close (GenIII's anyway) and I was actually the second highest. If we were on a Mustang these numbers would have been considerably lower too. We all know numbers can vary from Dyno to Dyno even when it's the same type of Dyno but all of these numbers sound high.

https://youtu.be/_jOO8xco-fI i have all the mods listed on my video... basically what helped me get 11.11 is my 373 rear gears.. my mods were at this time in this video, kn filter, bbk tb,cat delets, borla catbacks 2.5 in, underdrive pulley and sct tune from roe racing....oh and driver mod cuz i can luanch the shit out of my viper at track or street.lol i have also raced many gen 4 and 5 on streets and track and beat them ... dontnget caught up in dyno numbers, im just doing this to show what the gains are of just cam only car.

Sounds good! Were you able to swap it out without pulling the heads? I'm going to be doing a cam and ported heads this winter. How was the install? I hear it's pretty straight forward and you can tilt the engine and slide the cam in without dropping the radiator out.

[chicagopd50]

if your doing a cam install on a gen 3 , your going to want to buy slowbleed lifters.. gen 3 has fastbleeds... gen2 has slow bleeds...that being said. in order to take lifters out of gen 3 u need to take off the heads... its a 13 hour job.. my best friend did the install for me at his shop so personally i did not do the job.. but yes the radiator came off and heads also..in order to get the sound i got you absolutely need to replace lifters on gen 3... i took its out for a spin and boy o boy i felt the difference right a away of extra hp. i would say i gained about 50hp to the wheels... i will do a dyno and show b4 and after videos of results..

[06SRTCoupe]

Very nice Chicago. You should get some good power out of it. I know there was a guy named Tornado on the Viper Alley who dynoed in the 550's in his cam only Gen III. I believe he was stock gearing though and I'm not sure what he had as far as a tune or bolt ons but his car moved out pretty good. If you search his name on the Alley you can see what cam he had...it might have been the 710!

[chicagopd50]

Cool thanks... the gearing will not show up on the dyno sheet , dyno measures actually power... i have looked into that many times.. although I only have access to a mustang dyno which give u lower numbers, so I might be around 525hp on dyno jet since I did 480hp on mustang dyno .. and that was b4 the cam swap.. anyways we will find out what I gained by this weekend hopefully

[viper04blk]

to the OP, do you have to get an aftermarket computer for tuning?

[chicagopd50]

stay tuned, dyno video coming up late night dyno session...

[Stealth78]

Lmao. Yeah, missed that one...


Rusty hook, fresh worm and still no bite? I was barely on that forum before I got rid of the truck. It's just not the same around there. How have ya been?

I've been good, almost too busy to drive either the car or the truck though. I agree, the ol' VTCOA is definitely not the same anymore. I still have the silver 04 though, honestly I love those trucks.

Nice and nice driving. No worries, I really don't get caught up in Dyno numbers but sometimes numbers just sound a bit stretched. I also agree a Dyno is best used as a tuning tool. I haven't been to the track in 2 years, I miss it and really want to get back next season.

[chicagopd50]

Well verdicts in.. i did way better then I thought.. i have a graph of b4 and after cam swap.. ran the car 3 times it got stronger everytime.
..https://youtu.be/_vZnJocd_gE

[pony23]

The graph looks nice. What were the final numbers? When I blow up the graph it gets blurry. This might be a good winter project for me.

[chicagopd50]

583hp 571tq

[Rocket]

Congrats - Great numbers - especially on a mustang dyno! Sounds great as well!

[Stealth78]

Am I really the only one that thinks these numbers seem off? Mike, no disrespect to you at all bud, definitely not calling you a liar, I guess what I am second guessing is the dyno itself. 583/571 with no porting or internal motor work just seems insanely high to me. On average if this was a DynoJet you would be around 620hp, also you said that you have 3:73's which would also creates more parasitic drag probably pinching another 10rwhp or so, so if you still had 3:07 gears you would be coming in around 630hp on a DynoJet with no internal motor work.

[chicagopd50]

So after running the car on dyno 3 times 1st run 573hp 2nd 580hp 3rd 583hp. I was in shock. I didn't believe it my self. I told the dyno dude please check your dyno cuz i dont wanna look like a fool when I show this to people. He laughed at me and said look at that camaro , the camaro dynos at 380 hp, help me strap it up and I bet u that's the range. We did. It was 378hp.. then I asked him if my rear gears 373 played a role? He said no. His explanation was that all the mods I did before just kicked in and worked together in sync. So that being said im so glad I didn't waste more money on doing the heads. I must add though this car i have is a freak of nature. Everytime i dyno the car it always had higher numbers then a stock numbers should have when it was stock. My 1/4 times were second to none doing 11.11 at 125mph .. so i dont wanna make claims to something that I say that anyone can achieve. But no one ran a better time and not even close when I did 11.11s with just sct tune,cat deletes,catback,bbk tb and 373 gears. I have hit 128 mph several times but my times were not as good cuz my 60ft sucked.
