Head gasket failure 2014 turbo viper

[Cspittle]

Hello everyone new to the forum. This will be my first post. Going to try and make it short and to the point I have purchased a used 14 viper turbo with 3500 miles on it the turbo on it is the full mpi kit that runs the head shim and 10 psi of boost .took it for a ride and loved it seemed to run great. I took it home probably put 70 miles on it for the first ride and went to ride it again when I started the machine it smoked a lot for a 4 stroke and I could smell coolant but none the less I let it warm up and it over heated fast fan was on temp kept climing and the fan would not cool it down. I figured it had coolant in it because the over flow had coolant in it but with further inspection the radiator had no coolant in it I’m 99% sure this has a bad head gasket from the smell of it and also there is flakes of somthing in the overflow witch I believe is from the head gasket my question is how big of a job is this and is it common any input would be great I have little experience with these turbo sleds.

Its a pretty big job and is not something I would recommend to do if you do not have experience pulling heads on ATVS or 4 stroke engines. Have you done a leak down test to be certain it has a blown head gasket? Have you done a coolant pressure test on it? If it has overheated with a faulty thermostat then you would have lots of air in the system and would overheat really fast.

Thanks for the reply and mrsled i am actually a tech for a skidoo dealer been doing it for 8 years now. I did fix the sled ended up being a coolant leak haven’t had a issue since I fixed the leak. I do have a million questions but for now I am trying to figure out what helix is in the secondary I know it’s a dalton helix and all I can find on it for markings is 1521 also it says Hartmans on it. I’m not sure if anyone could shead some light on it I have tried looking it up with no success is there somthing on the back side to say what angle this cam is?

Might be something on side if it's a Dalton.

Hello again I would love to talk to someone about this sled that has a high knowledge on the turbo vipers I have questions and I think it would be easier over the phone. I would appreciate it if anyone is willing to answer a few questions. send me a message and I will give you my number again I would really appreciate it.

Get ahold of Studroes. He is the man.

I have 2 of them and was lucky enough to be the 1st person ever to blow one up in December of 2013!!!! What you have is a blast but can be even more fantastic! What muffler/can do you have? For 10#'s of boost what fuel pump upgrade is in it? are you running larger injectors or the 4th with separate GEMS controller plumbed into the intercooler. with a flash to retard timing, and proper fuel system and race gas the MPI Stage I is capable of close to 14#'s of boost and set up properly will get you close to 300 hp.

Say hello to my little friends! PS you can PM me if you want phone advice.

Hello yams dog thanks for the reply sorry for taking so long to get back been very busy the past few weeks. Love the red and white on the viper sweet looking sleds. So what I know about the sled it has the full stage one kit from mpi with over sized injectors I’m not sure what kind of injectors where I just got the sled it has the mpi quiet muffler on it also it has a 0.66 low compression head gasket and arp Head studs. The fuel controller is a power commander and besides that I’m not sure.

 

[Yamadog]

The power comander is the way to go and with larger injectors you should be able to dial that thing up a bit especially with the Lord compression might not be a bad idea to do an evil flash to pull sometiming though. The muffler is the real weak link it may be robbing you as much as 40 horsepower

 

[Cspittle]

So the evil flash how does it work do you just buy the tune and put it in? I have no idea how it’s set up right now would love to have someone that really knows set the tune and I didn’t know the muffler would be killing it I will definitely be investing in a better muffler if that’s the case

 

[Yamadog]

Yes there is Dyno tests on here proving the muflerm is choking them. The EVO flash is done by a bunch of shops like Ulmer you send your computer to them

 

[MrSled]

All this talk about Lord Compression and Evil flash is making me think I need to go to church. LOL

 

[slapshot]

Sorry off topic but.... what do you have there with the centerlines hiding under the car cover Yamadog?

Either we got 2 guys with a serious case of fat thumbs or auto correct is trying to tell us something lol.

I was able to do some dyno testing a few years back after I had the engine done on mine. I have larger injectors as well as a pc5 pti, I use Ulmer’s mapping and it’s spot on all the time! Mine has the .092” head shim, I run 12 psi on pump gas. When we did the dyno testing we tried the mpi quiet muffler, mpi race (aero) can and a D&D 2.5” oval can. We left boost set at 8 psi for all testing. This has been a few years ago so my numbers might not be exact but within a couple hp either way:

Mpi quiet muffler-181 hp
Mpi aero race can-201 hp
D&D can-210 hp

No changes were made in boost and we were dynoing on a 50+ degree spring day with afr’s bottoming out the a/f gauge at 9.00. Ended up turning boost up to 10 psi and still had it very rich at 10.2 and made 230 horse right on the money. So when yamadog says you could be down 40 hp with the quiet muffler..he isn’t kidding. Hats off to Allen Ulmer and his tuning though, if it were me and you had any questions at all as far as what’s in it for mapping I wouldn’t hesitate to shoot him an email. If you’d like to pm me if u have more questions feel free, I don’t know much but enough to be a little dangerous lol.
