Back to you Hemi31. You may have something there. I've had my tranny replaced and my drivetrain rebuilt several times from failures. One thing I contemplated was installing a high stall unit but never did... is a malfunctioning tq something which can be verified through the Diablo? Pressures or something of the sort? If so, how? My car does have 101,000 miles and my top speed attempt was after my tranny install.
Thanks for any advice on that. I might as well do my new modding all at once. And by all I mean, headers, cam, converter... and anything else I may want to add in the mean time.
Need I begin to list the mods....
I have a 5.7 magnum and Im in the 120 range in 3rd gear and no where near 6400 rpms and Im pretty much stock. Maybe someone else with the awd can chime in but I doubt it has that much to do with it but its possible. As far as Erik Hemi31 backing up his debates, you can count on that hes not going to say something if A. Its not true and B. He cant prove it. You did come across like you were calling him a lyar.
Mopar Or Bust
6.1 Cam, 180 T-Stat, K&N Typhoon CAI, Predator with Custom Tune, Underdrive Pulley, Magnaflow Cat Back, BT Lock Out, Taylor Shorties and Much, Much More To Come.
Although, like I said in several different posts, this was a friendly debate and didn't want it perceived as more. I'm actually glad to see that the SRT has such a powerful top end. I've always wished I would have bought one of the several I test drove before buying the Magnum. Like I said, my car is nowhere near what others are claiming for some effed up reason.
I'm glad Erik actually chimed in. Like him thinking converter... I've had my tranny replaced but the old converter put back in. I'm curious to know whether or not he's right, if its not locking entirely or if something else is wrong. I've bounced my rev limiter from 6400 to 6000 several times to see if any changes happen. I've played with the tune and now have a custom tune, but it just doesn't get there. I've powered along at 130 all day long. Its not like the car isn't willing to get there, it just doesn't have room for more. With my final drive being 3.08, there should be the same room as others... but she just falls flat on her tits.
I guess the good news is I do have plans to mod some things, including adding a high stall converter. I have a multigauge running on the OBDII port and will look to see if there is a read out showing what is going on. That way I can safely drive and keep my eyes on the road...
Its either that or I stick a for sale sign in the window and just bite the bullet... I've wanted an MSRT for years. Well, at least for the four years and 100k miles I've had mine.

Yeah I cant put my finger on why your having issues at that speed with being tapped out. Before the motor I got from Erik I was completly stock aside from cat back and I remember doing 130 and having alot left. The converter may be your issue so if your planning a stall converter then time will tell. Next time your getting on it try to clock what speed each gear shifts at. Then I could compare that to what I was running stock. For some reason those numbers stick in my head.
You can get to,and above, srt power on a 5.7 pretty easily and for less money.
As far as The Buddy's statements, you're falling into the Dyno numbers trap. Dynos are not calibrated or measure the same, which has been mentioned numerous times in this thread. Also, just because a car dynos well, doesn't mean it's gonna perform well at the track. We've all seen builds with great numbers on the Dyno put up horrible ties at the track. Some are due to the build not being dialed in, or a cam which the power isn't in a useable rpm range, or it's a high HP cam which doesn't put down the low end torque to get te car moving..
If his SRT dynoed at 360 (or whatever the number is) you can expect that your car most likely suffer the same percentage of low power.
If his verter isn't locking completely, that could mean more power is being lost through the drivetrain..
A stock R/T isn't gonna pull on a mildly modded SRT... If it does, something is wrong with the SRT, but I'm not sure that's the case here.
The Old: Stock 5.7 Bottom End | Lead Foot | 11.861 @ 112.76 1.63 60'
The New: Forged Arrington 6.1 | MMPG Top End | Paramount Drivetrain | 11.67
@ THE OP:
Dyno numbers are just that; numbers. Sounds like you and your friend need to make a day of it at the track. Report back.
Yeah something ain't right with your car. At 130mph it should just be getting into its' stride. Plenty (and plenty) of folks have taken essentially stock Hemi's into the 170 range.
Perhaps if you've read the string of posts you wouldn't be such a smart ass. As I stated I wasn't trying to be jerk. Although you may have gotten past the stupid part yourself and actually realized that I am learning something, something not known by many contrary to what you may have personally experienced yourself. Horsepower is something that people constantly talk about, as are time slips when it comes to cars. On the other hand, a fact the Hemi cars can be top speed machines when desired isn't exactly common knowledge. Who in their normal day could even fathom a though of a Dodge Magnum being as fast as a Dodge Viper? Think about it. Most people don't have open roads within their reach on a basis in which they care to open it up. You'd probably, if you had read them, also learned that for whatever effed up reason mine struggles through 130 and from my personal experiences is why the debate started.
Here's an idea, you too can do your own homework before chiming in. Its one thing to participate in debate and correct ones thought, its another to belittle. Hence, this forum is superior to many others out there, until wise asses like you jump in.

Although, if I did drive Ms. Daisy... then why is it I've blown apart two transfer cases, one tranny, and another planetary assembly in my AWD??? Must be because I waste all of my (factory proclaimed) 345hp going 0-100. I wish I could boast my brochure horse, but I know my car only puts down 277hp and 320ftlb at the wheels.
Understood my LX Brother, were good
I've got a Saab 9-7X, aka the Trailblazer. I just had a 6.0 363ci stroker built for it... its my wifes and we're members to a couple Trailblazer SS Owners forums. Is it just me or are (it seems like a lot) GM owners just a-holes for real? You should see the crap they say to each other. So counter productive, not helpful, and the forum members turn over like no other. I mean, we all may say something on the forum that rattles some cages, but I've yet to come across a thread on here where members haven't learned from it all.
To be honest, I'm actually glad I did what I did, otherwise I would likely never have known my car is doing whatever its doing. At least not for a while more. For hells sake, I did a little S curve test today to put some load on it under acceleration. Great short sprint on a flat just up the road from my house into town... two times, once each way, I carried different rpm at same speed. 90mph each way actually. It's now obvious that under such load something isn't doing what its supposed to be doing. I have been running some friction modifier as I've gotten some issues since my tranny was replaced. I'm thinking its water, they replaced the tranny but I'm sure they never did the service bulletin for the fill tube and we had a pretty wet slushy winter. In general, my dealer sucks. I picked up a slight rattle and slight shudder again, added the modifier and it has fixed it. I've been good for quite some time. But I'm thinking that it was all part of a bigger evil. I'll find out next bonus, in about a month or so, its time to put that nice stall torque converter in. Might as well do it and do it right and add the Mercedes fill tube with level check and flush and seal the tranny again.
I got to tell you, its sh*t like this that really makes me wish I would have just bought the SRT. But, I didn't and it was all to save a little bit of money... what was I thinking, I test drove 2 300's, an MSRT, and 2 more GCSRT's...
At least I've got the Magnum and being a dead breed, I think I'll hang on to it. Besides, it makes for great conversation piece when people see what it looks like and can't actually call it a grocery getter.
I agree, i'm on the Corvette Forum here and there and they bicker with each other like kids. I ordered my car and when I went to pick it up they had an RT with the Road And Track package there, so while they were getting my car ready I asked to test drive it................good car, but not even close to the rush my SRT8 gave me. Worth every extra penny
