That's disappointing that you had an issue with your engine at that level of boost, Greg. I'd be surprised if it wasn't tune related. Hopefully your vendor steps up on this one.

This wouldn't be the first Vortech blown HEMI at relatively low boost to go due to a tune.

Wouldn't limit that to Vortech's...I have seen folks with every type of system have issues due to a poor tune. There have been a few of late on this forum with Vortech's and in every case they have been running a custom vendor tune.

 

[HemiSam]

That's a fair point. It's not just the Vortechs.

im thinking tune also.. 6psi and 470 hp is high numbers.. speedy did you run any logs.. check iat's? air fuel?

Never got a chance to check it

Why would you use a custom tune on a stock setup when the kit tune is tested tried and true? Are shops looking to get more money out of the install?

I get it if you have other mods , but if the only mod is the SC, Use the kit tune.

I didn't use the KB kit tune, my tuner said that he could make it safer. Don't know if that's true , I hope so. So far so good,

^^^Custom tunes are almost always better than a one size fits all kit tune since they are specific to the car being "tuned".

Sorry to hear about your motor bro, hope your up and running soon:thumbsup:

I may have misunderstood but the kit I bought was a tuner kit. It had to have a custom tune put on it. And like Speedy said each car is different. You can get more hp with headers high flow cats & exhaust like I have.

Thanks lowlife. I will get it going again pretty soon. It will be bigger better & faster.

Very true if the tuner knows what they are doing, but more times than not, it seems that custom tunes run closer to the edge...which is fine so long as the customer knows that and is shooting for the max, and knows the possible ramifications.

That said, I have yet to see or hear of a failure of anyone running a canned Vortech tune in 3+ years...yes not max power, never will be, but also not popping motors. Every failure I have heard of has been with a custom tune.

Seems there are only a handful of tuners in this country that truly understand how to tune and FI Hemi, that becomes more clear by the day.

Yeah, seems that's the case for sure.

When my bud (Bearair) purchased the Vortech back in late '09 the canned tune supplied wouldn't start his R/T so he had to flatbed it to a local speedshop for a custom tune to get it going. Now I realize they've come a ways since then, but a proper custom CMR tune is the way to go if the tuner truly knows what they're doing.

The rub is I don't think they're all that many good hemi tuners out there, especially with it comes to the 2009+ 5.7 based motors. That doesn't keep them from selling and tuning, though. A good vendor will back-up their sale with the appropriate level of support and I'm hoping LUV sees that kind of commitment.

I don't know if this is a option. I'm putting in a 426 and my engine only had 6000 miles I think 8000 at the most. For the core charge I'm sure you can have it. I'll just use your as a core. As long as it would make a core. Can't imagine it wouldn't.
I would need to get this OK'd with Josh. I'm game if you are.

Wait RT might not work? I have a SRT.

SWEET !!! That's the bonus of blowing a motor:thumbsup:

 

[DCX Depot-Tim C]

I agree 100%, tuning is very important to keep the hemi running properly. We have tuned thousands of hemis, heck in the summer months, we create over 200 hemi tunes PER MONTH. We have had over 4,000 cars on our dyno, with many of them being Hemis.

When trying to "Guess" whats wrong with a car, its important to have more information. One should not simply say, yep, has to be a tune. Parts can fail as well. This particular car has had numerous fueling issues, leaving the car stranded more than once. The owner has run his own wiring to power the fuel system after it had issues. He even called about 2 weeks ago to say the fuse blew on his homemade wiring and that he was going to run a different type of fuse and wiring that wouldn't pop so easy. It could have damaged BAP, pumps or other parts.

We get tons of calls daily from people around the world wanting an over the phone diagnosis as to why their car is acting funny, I tell them without it here, its far to hard to know for sure.

So to blindly point to any one piece is foolish. I suggest and have suggested to bring the vehicle in so we can try to determine the causes and solve the issues.

This is a sweet car and Greg is a nice guy. Hopefully we can get it solved and have it up and running quickly to enjoy in these summer months.

Thanks,

 

[HemiSam]

Fair enough, Tim. But allow me this. How many of those thousands were tuning a hemi with a blower you installed? And of those with stock bottoms, how many of those have failed? I've seen failures on this site and others. Certainly not all yours. But the question stands and more importantly given you're one of our vendors and one I've done business with, what are you prepared to do for LUV?

You may not want to address these questions to myself, but I would think LUV would be due the responses.

As for the BAP he wired, I thought that happened because he was having trouble after the install??? I could certainly be mistaken. I am about half the time ;-)

well I gotta agree with Tim here. a fuel pump thats blowing fuses could easily be causing lean conditions if its flaky.

and a tune is only as good as the rest of the system. and if the system changes out the door, then you can have these issues.

I remember trying to tune my AAR years ago after installing a BG Fuel pump and regulator. The regulator would vary its settings almost constantly. sometimes fat. sometimes lean as hell cause the fuel pressure was changing. I remember having to adjust and readjust that puppy several times before I realized it was just a POS and wouldnt hold a setting. Within a few months of trying it, I blew the tops off my pistons (detonation caused by a lean condition).

I can see your all trying to hang DCX here and its not necessarily the right place to point your finger yet. When you modify a car for high performance and then run it hard, THERE IS RISK YOULL TOAST YOUR MOTOR.

like my dad always said, if you want to be Johnny Race Car Driver, get ready to spend some money, and replace some broken parts

 

[RMG]

The car had no gauges,owner did no datalogging at the track & messed with the fuel boost system.He needs to step up & take the blame.He drove it home 140 miles also:notallthere:

 

[aarcuda]

and thats another thing, when you mess with a car, you better sure and hell be datalogging parameters to make sure everything is working right. if youre running down the track at WOT and your pinging that beotch, I can guarantee youre going to lose a piston.
