07 MSRT8 - First Dyno Pull results - this normal

[alpinewil81]

I'd have to guess your converter is not fully locking.

First, JCSRT, Hemi31 here is shedding some light on the matter. Just don't want you to think I'm as an LX owner is being a d*ck to another LX owner. This forum is great for keeping people informed and getting along. I've got a Saab 9-7X we built a 6.0L for and the TBSS forums are full of geniune arrogant a$$holes.

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.

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.

Word. I wasn't calling out Erik, if anyone was called out, it was JCSRT8. I wasn't calling anyone a liar, if I were, I'd have said its impossible then argued the hole thing not discussed what was going on. Quite frankly, very few care to know the top speed capabilities of our cars, many more care to know horse... I prefer time slips and mods. Not like I said any of it wasn't possible, but from what I've personally seen, it is not as common as those who've attained it would believe. Its like living in NY and having a home depot built 20 blocks down the road. Most find the nearest subway station and have no clue the Home Depot exists. I'm impressed with the few that have identified high numbers, but most who posted either are not or are far from stock. My inquiry is about stock cars.

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.

[silvermagR/T]

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.

[JCSRT8]

Should do this in a pm, but you posted it here so I'll call you and raise you.

1. Chirping in second, with an SRT I'd certainly hope so.
2. Unless you're packing forced air induction or a lot of nitrous, 0-60 in the 4 second range? You're clock needs recalibrated.
3. 170 mph? Good luck with that. By 130 you're so deep into your redline you'd need a 6th gear to get even 150.

Don't want to be an ******* to another LX Owner, but I will ask the question of what makes yours more special than the other 100k SRT's out there?

Wow, i cant beleive you even called me out on this, but it doesnt surprise me when non SRT8 owners and people who drive miss daisy all day throw a BS flag on someone elses comment. No hard feeling though, but the facts are this................ 170 mph bone stock and for the record 4th gear takes me to 160mph and fifth has taken me to 170 mph plus a few times with ease. What makes mine different from 100k SRT's out there??? Nothing except im not afraid to floor the **** out of my car and do what it was built to do SRT!!!! If i wanted to do the speed limit, i wouldve saved myself $15k and got an R/T. "By 130 you're so deep into your redline you'd need a 6th gear to get even 150" ??? Dude you obviously dont know jack **** about SRT8's, 130mph is all but barely out of 3rd going into 4th @ 127mph. Do your homework first next time before you call me out on a car that i drive at will and actually have and have done the things i claim several times over and so have many others who actually drive an SRT8 the way its suppose to be driven and not wasting 425hp doing 0-100.

Great thread.

@ 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.

@Alpine:
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.

3. 170 mph? Good luck with that. By 130 you're so deep into your redline you'd need a 6th gear to get even 150.

ROTFLMAO!

Thank you for the laugh...

Do your friends own a "I'm with stupid" T-shirt by any chance?

Their is some irony in that, they all own an "I'm with JAAK T-shirt".

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.

Hey, I'll apologize to you as I wasn't trying to be an a-hole. I will say, had you read the posts as well you'd learned I stood corrected. But look at both sides of the table, its not like 170mph station wagons are the topic of discussion at everyones dinner table. Dynos and Time Slips both trump such discussion on the forum about 50:1. I will say from my experiences in the SRT they had the power but they didn't have the breath. I can't explain why, they weren't my cars. My own car however appears to possess its own gremlin that makes it damn near die trying to get past 130. Something I've got to figure out. I've taken my old street bikes, my 300Z, my 240SX, and my old Supra to such speeds... but they weren't station wagons. Its all a rush for sure. SRT or not, the Dodge Magnum is not exactly perceived a super car no matter what we all may think or know.

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

Understood my LX Brother, were good

Mmm.... beer. Just had one actually. Thanks, its nice knowing the guys on this forum can debate, learn, and move on to still be enthusiasts.

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.

[JCSRT8]

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

You know the 0-60 timer is not accurate? With ESP off no less......
