 Subject: Who has a 14 .0 1/4 mi. time or better?
IP: Logged
Message:
Just wondering who here has been to the track and gotten a 14.0 or better time slip in the 1/4 mile and what your set-up is? I would especially like to hear from any 4.7L guys, but would also like to here from the R/T guys as well. I own both, and have gotten a best of 14.7 with my Kenne Bell Supercharged 4.7L 4X4. I haven't had the R/T to the track yet. I know it's faster than my 4.7, just not sure by how much yet. I'm shooting for low to mid 13's with the R/T by the end of the year once it's supercharged. Anyway, just bored and figured I'd see what times the "fast" crowd is running, and how they got their truck there.

I'm gettin there...I took mine to the track only a few hundred miles after the break in of my heads and cam so everything really wasn't in sync yet but I did do better than before I had it on...the best I could pull on slicks w/ the temp outside at about 90 and the humidity of about 60% I did a 14.42. I know therez some R/T's out there that'll do that stock so I've heard but it just depends on the elevation your at and conditions. A few other guys at the track w/ heads and cam work who did have theirs broken in were pulling near the same times I did so I know it wasn't just me. The best one guy did w/ a setup like I have ran a 14.1 on slicks.
Signman if your gonna supercharge your R/T I highly suggest you get the M-1 2 or 4bbl...probably the 4bbl if your gonna supercharge it. Your stock intake manifold is restricting your top end big time.

A buddy of mine has a '99 RC R/T with a Vortech
SC, mild head work, headers, ignition and no cat.
His truck has run as quick as 12.20s @ 111 mph
with the stock beer barrel intake. Part of the
truck's strong ET numbers are the 1.6 second 60'
times. A good reason for those good 60' numbers
is the stock beer barrel intake manifold. It's no
slouch in the mph department either.

Hey Dunner I finally got one of your mpegs to work, do ya have any more, hehe?
What do you think my 2002 CC 4x4 auto, 3.92's w/ LSD, and all the HD options would run with the right tires and a motor setup like yours? (roughly)
My college buddy owns his own shop and said if I pay him a visit out in PA which is a few hour drive, If I buy whatever he'll put it in for me. So now I'm waiting for someone to put out some cams, a little more potent than the HO cams.

my estimated 1/4 was a 13.425 by calculating my 1/8th mile times. But i have really bad 60 ft times due to an open differential (2.2 60 ft). this was all done with a mild shot of nitrous and no supercharger. I think i am gonna do some more body mods and frame mods and loose the s/c and get the nitrous back. Then i will put on a limited slip diff and run some more 1/8th. The first time i go to a 1/4 mile track around here i want my six banger to pull off some 12 second times..... that would be so cool.

Trust me he would get alot better times w/o the beerkeg...if you've seen the inside of the beerkeg its like every port for itself all the air is just flowing into a big open space its not a direct shot into the port. With the M-1 its directing all that air straight where it needs to go. Its not the beerkeg giving him good times its the SC and head work thats doin that. If you've ever felt whats its like to go from the stock manifold to an M-1 you'd know how much better top end it gets...its unbelievable, they should've put it on the R/T's to begin with, of course Mopar doesn't make money if they did.

True - he would improve his top end charge, but at
the cost of his awesome launch. He's considered
the M1 in the past but hasn't installed one
becuase he would need at least a stall convertor
to make up for the loss of bottom end on launch.
Have you ever seen a Dakota run 1.6 second 60'
times? There's no way he'd be able to launch like
that with an M1 unless he had a stall convertor.
The M1 moves the torque curve up to the point that
you can't launch that hard without the convertor.

Duner, in your opinion, since I've allready done the 4.56 gears would it be in my best interest to go with the M1 2bbl? I've heard so many good things about it, that's what I was planning on doing next. (That is after I install the headers, 3" cut-out, & 3" hi-flow cat.) I don't have a stall converter, and did't plan on getting one. The gears really made a differance I could feel on the bottom end though. Truck launches great.
After I did the M1 I was going to start saving for the SC. What kind of mild head work did your friend do? Maybe this is something that I should do first, then the SC. Any thoughts?

The 4.56 gears are a big improvement and help the
bottom end torque issue with the M1 by quite a
bit. My friend didn't want to go with the 4.56
gears because he was already pulling right at 6000
rpms going thru the traps as it was with his 26"
tall slicks. Lower gears would have meant he had
to use OD on the track and he wasn't comfortable
about it handling the power. He basically quit
modding the truck because he was already just
about at the limit as far as ET and safety
equipment. He didn't want to install a cage since
his wife drove the truck to work every day and it
was afterall just a street truck.
His heads received some mild port cleanup and some
bowl blending, but mainly the combustion chambers
were mirror polished to allow him to run up to 15
lbs of boost. He also went with different springs
and roller rockers to help keep things together at
the rpms he was running the truck to.
Don't get me wrong.... the M1 is a good
performance manifold and improves the HP quite a
bit after 3000 rpms. It just moves the HP and TQ
curves up in the rpm range. If you pull a trailer
you wouldn't want it. The 4.56 gears will help but
there is certainly a difference in the amount of
torque you will see under 3000 rpm.

Thanks Duner, you've got the wheels in my head turning now. I was pretty much set on the M1, now I'll give it a little more thought. I don't have a 1/4 mile track near me, but there are two 1/8 mile tracks fairly close I may take the R/T to every now and then. It's not my daily driver, just take it out when the weather permits to cruise the streets. I really like the low end torque it has now especially for those stop light to stop light races I seem to get into every once in a while. Since there aren't a lot of straight, safe, stop light runs that go for a 1/4 mile around here, I may just use that money for the M1 towards something else.
Then again, who knows Mike. I saw on another R/T board awhile back that someone posted dyno runs with the M1 and got some serious gains.
<http://forums.delphiforums.com/dakotart/messages?msg=5779.1>
It shows a 56HP peak gain @ 5,600 RPM & 40HP gain from 4,600 to 5,600. The only prob. is it doesn't show what happens under 3,600 RPM's soo... losing a little bottom end to gain that much on the top end, especially since I have the 4.56 gears may be a decent trade off for me. I'll have to give it some serious thought now.
I know most people use the 1/4 mile as a referance towards performance gains that's why I posted the question the way I did. But what I'm trying to get the truck to do is go from 0 to 80 as fast as I can. I rarely race on the street faster than that, and I'll do well at the 1/8 mile tracks near me. After the SC goes on (prob. next year) I'm definately taking it to the 1/4 mile track to get some "real" times to post.

I cant wait to put on my M1 2bbl. I cant wait to feel it pull all the way to redline instead of sufficating after 4000 rpm.
I bet the M1 doesnt lose that much TRQ under 3000 rpm. What , maybe 10-20 ft/lbs ? And when you race the tach is only gonna be below that in 1st gear. So at the end of 1st gear , all of 2nd and 3rd gear most of the time spent at WOT will be 3000 rpm and above which is where you need that breathing ? Am I right ?
I dunno , if you want all TRQ below 3000 rpm , and no revving power , buy a diesel.
Maybe I should change my name here to low_torque. LOL

Wesley, that's what I'm talking about! That's awesome that you got your Club Cab in the low 13's with the few mods you have. And on the stock RS-A's!! I've often thought about going the nitrous route, but because I don't go to the track often, and can't use it on the street safely, I'll pob go with a SC.

Message:
I did some searching on the RT list......
M1 owner #1
Well just finished up puttin my M1 2bbl on today. Id have to say it pulls great after 3500 rpms but below that its a complete dog. before with all my previous mods i could smoke the rears for 150 feet without a problem. now i barley get any tire spin off the line.
M1 owner #2
As you all know,ive been having a problem with lack of low end since my m1 install. It will barely chirp the tires wot from a stop. Does anyone know how to cure this without taking my new M1 intake back off?
M1 owner #3
There is a difference between the hooking off the line and the bog you will feel. I was doing 1200rpm stalls at the line and barely able to get a squeak out of the street tires. With my stock beerbarrel it would spin all the way through first.
M1 owner #4
I put a 2 barrel M1 intake on my truck last weekend and I'm pissed. This thing has no balls off the line any more. It feels like a rocket when I floor it from a roll but it is a total dog when I nail it from a stop. Why didn't anybody warn me that this was a race only mod. I can't afford to buy a stall convertor so what are my options?
M1 owner #5
I read all about how great the M1 intake was going to be for my truck. I'm very happy that it hauls ass now but something is messed up. If I floor it from a dead stop it will barely turn the tires over. Is this the loss of low end that everybody was talking about?
Don't say that nobody warned you.

Exactly. I bet M1 owners 1-5 thought they were
going to have thier cake and eat it too. All they
knew was that their peak hp number was going to
increase because they read about somebody's dyno
chart online. More than likely they never read a
thread like this one where somebody explained
about the tradeoff they were making. Most mods are
a compromise. Either a looser convertor or lower
gears are needed to compensate for the trading of
bottom end power for the top end charge. It's not
just about burnouts. Drivability is a big factor.
The off-idle torque feel is what most people like
about their R/Ts to begin with. As long as it's
understood that you are trading power in one area
for power in another then it's all good

big_torque - You are sounding like a pretty big fan of this mod for somebody that hasn't even done it yet. You be sure and post how your truck feels AFTER you install the M1 intake on YOUR TRUCK. Do you have a stall speed convertor for your truck already? I didn't want a stall convertor in my truck! They build lots of heat and make these heavy trucks feel too slushy for my tastes. Now it looks like I will go with lower gears to make it work better. It does pull harder once the truck is moving but it feels pretty sluggish until it gets above 3000 rpms.

maybe my other mods are making up for what is lost with the m1. before it would just barely bark them when i hammered it from a dead stop, now it lays about 15 feet of rubber.

I have an M1 on a '99 Club Cab with a 318,A500,3.55's , If anything it improved the low-end and throttle response. I went from running 10.20's@68mph with 2.18-2.24 60' times to running a 10.04 @72mph with a 2.75 60' time and lots of spinning. The only other thing I've done is ditch the cat and put on a 2.5" Dynomax muffler.
On a different note though I was grudge racing a guy that night with an '02 R/T RC with an M1 , Jet chip , TB spacer , 24# injectors , no cats and a 3" Flowmaster 2 chamber. He ran a 10.16@69mph and had 60' times in the 2.30 range with no spinning on RSA's , he was saying that the M1 killed his low-end and that it was running 9.80's with 2.20 60' times with the stock intake on it.
I can't wait to get the MP camputer , 2,400 stall , 3.92 gears and some BFG Drag Radials on mine to see what I can get out of it.

I have a 5 speed 318 truck and I recently put the M1 on my truck, noticed a loss of bottom end torque but I will tell you that the truck feels much faster then before. With the stock intake it would burn the tires uncontrollably through first and second, and into third. Getting on it in first was impossible. The power became much more usable after the intake, truck pulls hard all the way to 5,300!

what M-1 are you guys talking about? if its the 4bbl, yes, you will lose some torque. if its the 2bbl, i have one on mine, and didnt notice much (if any) loss. you can always move the map sensor line to the manifold insted of the throttle body. this will give you better throttle responce.

Message:
Since the M1 intake was something I was thinking about getting, I certainly don't mind having the thread take a turn in this direction. I welcome all input on this as well.
Bone stock spinning through 1st and into 2nd was no problem for me. After adding the 4.56 gears and MP PCM, ported TB, and Cold air intake getting on it in first was impossible. I have to ease into it and get the truck rolling good before getting down on the throttle. I am thinking that the M1 may make the power more usable for me. Especially since I'll be using street tires, not slicks, even if I take it to the track every now and then.
Thanks for all the responses, keep 'em coming!
