What should I replace next???

[BLWNSRT]

So I have been having HP problems since installing a roe supercharger The best power I made was 494rwhp and 507rwtq at 4.5#s with a 11.4-1 A/F since then I have installed mopar longtubes and catless mids and BBK tb.

This thing on the stock tune ( for charger) runs pig rich 10.2-1 on another truck that was dynoed in Florida with the same basic set up was 12-1 and well over 550rwhp

should I replace the PCM? 7 days away, it was a California truck

I make 5#s on my mechanical gauge could be around 6#s Also mopar performance gauge. I have msd wires ngk colder plugs the bypass valve is ok.
Bbk tb made it worse lost 10hp the supercharger isn't as loud as yellowvenom's 3.3l lynsolm but that could be because I have the 3.4l whipple

any ideas I should be at 550rwhp and a/f around 12

Get hold of Sean Roe for the better tune/ pcm:rock:

I have we both can't figure out why mine is so much different than all the rest of them he did the tune that did 494 and a 11.4-1 a/f we can still do morebut want to know why this one is so different. Compression test was all good haven't done a leak down test yet.

 

[DevilDawg3097]

how long have you had the s/c on?

 

[JTS VENOM PERFORMANCE]

degree the cam, could be a number of things, flash the pcm to stock and start all over

 

[DevilDawg3097]

When you put the injector harness back on did you squeeze the tabs to close them again. They get really loose on the 48 lbs. And you won't throw a code either (getting enough to satisfy the ecm, but not enough to spray fuel). Just a thought.

I will Ron, also it's been on since October last year but it's been parked all winter had it running since about 3 weeks ago. Injectors are good and tight, I have returned to stock with the sct many times and reinstalled the programs still the same thing that's why I was thinking to replace the PCM.

Here is the email i got from Sean:

Attached is the first pull with the mid program we use, with no modifications.

It was done yesterday on a 2004 Regular cab with Belanger headers and full exhaust.

Stock engine, standard blower, no changes otherwise.

It made me feel better that the tunes haven’t changed or anything.

I’ll be glad to help adjust the AFR on yours and think that for whatever reason, it does need specific tuning.

The tune being rich doesn’t fully explain why it’s so far down on power though.

If the timing, boost and AF are all there, but it doesn’t make the power, something else must be going on, but I could only speculate and don’t think that now is the time. We know yours is rich, so let’s get that sorted out.

Let me know when you’re in a position to log MAP voltage, RPM, spark and Air/Fuel.

I’ll need a line that looks like this in order to tune remotely:

2,000 RPM, 2.39V, 19D, 11.0

Let me know what you think.

 

[rottenronnie]

That seems about right for a Roe and where they should be as far as I'm concerned, and the kind of gains Sean advertises as expected gains, on his website.
We just don't see it around here either on the dyno or at the track. In fact, not even close.

That's not a slam of any kind, just what I've seen from others with the system on their own trucks...

I think Prof's was 622 wheel after Sean tweaked it for some time and before Prof did his forged build.
So in other words it was properly tweaked.

You can climb into the 700s as you know, with nitrous, etc.

Ok may have found something while i was double checking the fuel injectors i was looking at the pcm connections and found that I have had a pcm reflash could that cause it if so i can get a pcm in 5-7days

here are the pics anyone know what software upgrade this is for:

 

[JTS VENOM PERFORMANCE]

Ramcharger, save yourself some time and pain, shoot torrie a pm and see if he can help buddy, [email protected], he may suggest a sct, but jsut tell him you are just beat up spending and ask for his help or suggestions on the computer side or the tuning side, torrie developed the tunes for the vipers with SCT so he knows the system pretty well buddy

 

[FastSRT19]

Will the PCM from an 05 work in an 06? If so, i have an extra laying around you could have to see if anything improves...

No they are programmed to the vin, i changed one in another 06 last summer.

I had sent Torrie an email last weekend, he said wait to see what Sean can figure out first with his SCT stuff so i dont have to spend any $$$ at this time. I was thinking it could be a pcm problem like the other 06 i did had O2 sensor problem i replace the PCM and it was all good.

to me with what you have you are about 100 short, now you can send the puter off to BG chrysler , have them put a decent stage I performance flash on it, they offer overnight service, and have them turn the fan on earlier while you are at it, that will kill two birds with one stone.

not sure, but something is amiss, jsut hard to diagnose over the net, but if you have the funds, try the pcm , that way you start with a clean slate on the tuning part

Hi Tony Mahn-

Oddly, the truck sounded like it was aok during the pull on the dyno. I seriously doubt there is 100 in the tune. Maybe 25 or 30 but 100 would be a real stretch.
I agree, use Torrie and or Sean as a resource but something is "not quite right"..Hopefully we can fill in some major blanks and get it rockin' for Jeff. It needs some help, without a doubt.

 

[LoveThisTruck]

I hope you get this figured out soon:rock: You should be right around 550rwhp on 5 psi. I was at like 560... some claim 600+ Good luck!

Do you have a dyno sheet you can post?

 

[JTS VENOM PERFORMANCE]

he is at least 50 short, but with all his mods , he should be pushing the upper 500's

I would still start with a fresh pcm flash

but its funny and all have seen it, one truck may make 420, the next 400, so there are many variances to these engines, each one seems to have a mind of there own,

personally I dotn like dyno figures, its whether or not i like the feel of the truck , what I ahave done to it and if I am happy iwth what it does

Like tony said each truck is different read this article.

Supercharging An Automatic Dodge Ram SRT10 - Blown Away!

Stock SRT10s Are No Match For This Supercharged Beast
By Mike Finnegan
Photography by Vic Moore, Roe Racing


We've road-tested Dodge's Viper-ized Ram truck several times, in every bed/cab configuration offered. We came to the conclusion that those who opted for the standard cab/six-speed manual version of this truck scored huge in the power department, and the guys who ordered a crew cab/automatic tranny truck got hosed by Mopar. The truck with the manual transmission gets with the program with insane acceleration and top-end performance, while the automatic...well, it's not setting the world on fire by any means. The automatic-equipped truck is a nice cruiser that makes a good high-performance commuter truck, if you don't care about fuel economy. But, what do you do if you want to feel like you really did get a 500hp engine in your truck? Call the guys at Roe Racing for a new supercharger for your Viper engine.

Roe Racing is a high-performance shop out of Green Cove Springs, Florida, with years of racing experience, research and development, and installation experience behind it. The company specializes in performance enhancement of Dodge Vipers and, more recently, Dodge Ram SRT10 sport trucks. Roe offers everything from pistons to high-flow induction systems and exhaust systems for the Ram. Its positive displacement supercharger system for the SRT10 is a well-engineered and finely tuned package that integrates cleanly into the confines of the Ram's engine bay.

Roe Racing confirmed our suspicions that the automatic trucks are putting fewer ponies to the wheels by strapping Demon Carburetors owner Barry Grant's yellow Quad Cab SRT10 to its chassis dyno. The dyno revealed that the Dodge was only putting 384 hp to the ground. That's a far cry from the 500-plus ponies the 10-cylinder V-10 engine cranks out. Roe Racing also noted that the Quad Cab automatic trans-equipped trucks routinely put out less power than their six-speed manual brethren on the chassis dyno. Why the drop in power? Parasitic losses brought on by transferring the power through the automatic transmission is one reason, but eating up this much power is abnormal. No one is sure why the power is down this far, but the new blower kit is an easy, if not inexpensive, fix. Here's a quick look at the kit, the installation on Barry's truck, and some pretty impressive dyno numbers.
