 Subject: 4.7 to SMOKE an R/T???
IP: Logged
Message:
I just bought a 2001 clubcab 4.7, I set it up with 17x9 R/T rims but with Sumatoma 255/55/17 Z rated tires so they stick better than the eagle rsa's on an R/T. MY QUESTION IS WHAT DO I HAVE TO DO TO GET MY 4.7 to smoke my friends stock clubcab R/T? Also where can I get this stuff and at the best prices, and what is best, Im thinking performance chip, headers, exhaust, cold air intake, possibly throttle body, etc. ALSO how does a 4.7 stock, compare to a R/T stock in a race?

Well I'll take a shot at it. I have smoked a few R/Ts with my 2000 CC 4.7 5 speed 3.55 rear and the mods I have are:
Jet Stage II Flowmaster Delta Flow 40 1 in 2 out, Z-Tube intake from intenseperformance.com and autolite 3923s. I will be adding a set of JBA headers when they come out and a new TB next week and should have some new numbers the 17th. My best run was 14.9 and that was with only the flowmaster

If your 4.7 is a 5-speed with 3.92 gears you should beat up on him already. i have a 2000 4.7 cc 5 speed 3.92 geared dakota and have been beating stock r/t since day 1.

Bernd -- in your track experiences have you ever ran across a quad cab with 5.9L and 3.92 gears? I'm not sure how often (if ever) I'll hit the track, but am curious what I might be able to achieve. For now, the only performance mods I plan on installing are the Stage II intense performance air intake and probably a Dynomax ultraflow muff. I think I'll buy one of those G-tech Pro jobs just to play with, but don't realllllllly know how accurate they are. Anyone have much experience with them and their accuracy?
Thank ye thank ye.
p.s. I'm chompin' at the bit soooo hard to get my foot into the new quad cab. Wish they'd hurry up and ship the SOB!!!

BH, NEVER say "Can't", Flowmaster, K&N, PCM, and slicks got this 4.7L to 14.2 @94.49. Since then I've added a F&B TB, and Bernds IAT box. 13's are very realistic now. Hughes Engines is looking at cams and ported heads as we speak.
You sound like a lot of RT guys at my local track, "the 4.7L can't beat me", boy are they dissapointed when they see my taillights.
360 cubes and only mid 14's ???? 360 cubes.., chop off 2 cylinders and get that thing closer to the 287 cubes we're using, then see how the 360 responds.

Does almost every 4.7L owner say they run low 15's even 14's stock just to justify not getting what they really wanted? The R/T! I'm not sure about that 14.23 1/4 time with a lightly modified 4.7L. Sounds like a 14.9 at most. Your saying that just throw on a few items onto a 235hp engine and it now kills 380hp Lightnings. Sure!
I could be wrong, just post that time slip. No G-tech crap. Also what location, temp, humidity, pressure, altitude. Come run that 4.7L in the middle central US, it will huff and puff to get into the 14's. I was at the track just a week ago (very bad weather for racing) and saw new Corvettes running 14.5s, and much more running slower! I had the fastest truck, :) yes it's only ran low 15s Stock R/T. It was nice Vs some 16.6's that a new RC Sliverado was pulling! LOL 285hp my ass! All I'm saying is, don't dog on the R/T it's a nice truck and there are some that will eat your truck and crap it out without even trying. Lets be glad that we can even get V8's in a truck of this size.

Im sorry guys but if you put your money in a 5.9 theres nothing 4.7s could do to touch it.
The 5.9 with heads and proper pistons and all of the other bolt ons is a 500 hp engine. No if you found a 5 speed for that. Good luck trying to beat that.
I bet a very experienced engine builder could make over 1000hp using turbos or what ever out of the 5.9. The 4.7 is pretty strong from the factory but the 5.9 is held back and the parts to make it fast are easily availible.

If I wanted to spend a bunch of money for a slush box, over rated, Reduced/Towing truck, then yea you know what I would have bought, if I would have believed the Marketing folks at DC, BUT, I knew were the bang for the buck was, and thats what i got.

Like I said go to dragtruk.com and check out the 3.9 cc running low 11's. Are you only gonna settle for 12's when a 3.9 is running that, that's what you sound like. Grow up, oh you're probably still in high school, sorry. Let's see how many R/T's have you seen or even heard of running low 12's high 11's??

Matt are you telling me that your 4.7 is running .25 slower then a automatic 350hp 360Lb corvette. In the quarter mile its all about tourqe and the 4.7 doesnt have it. I just bought a 4.7 dakota club cab with 5.speed and its a very nice truck and yes it is fast but i used to own a 5.9 durango and even though it was slower then my dakota that engine had punch and from 0-50 it was leathel. After that it started to leave the Torque curve. But that engine in a pickup 2wd and 15 more hp plus after they put a k&n filter would destroy you. My durango totally killed my friends 4.7 auto quad cab and thats still lighter then the durango.
One thing you have to remeber is that when you put a air induction system on your 4.7 you maybe pick up about 12hp a 5.9 will pick up about 24 hp because of the crap chrysler system that is on stock. The 4.7 has a really good air system stock.
Next the biggest hp holder on the 5.9 is the y-pipe and manifolds. Change them and maybe you pick up an other 20 to 30 hp. I heard that changing the manifold on the 4.7 is useless because it doesnt do anything for you.
SO what im trying to say is that the 5.9 is running de-tuned and the 4.7 comes from chrysler running really close to its top capasity.
As for fuel pig. My 5.9 durango with k&n got about 13 - 14 on the high way and the 4.7 is gettign about 15-16 so big deal wheres the diffrence the paper on the window at the dealer said 18-19 mpg thats total bs. The 4.7 is almost as bad and on top of that i lost about 10 L fuel because the tank is smaller. Go put equal sized trailers about 1000 Lb behind a 5.9 and a 4.7 quad cab and the 4.7 fuel light will come on first.

Matt Y2K-Hemi,
4.7 Hemi, LOL
My 2001 RC R/T puts out 15.1@89+ with no mods with only 5k on the motor. Just fine for a stock truck! I was thinking about the RC 4.7L 5-speed, but I was turned away due too wanting 17" rims & tires, Wheel Flares, LS3.92, better suspension, fully painted front bumper, more CID, Didn't want a long stick in a truck, now small short throw stick shifters in cars are very nice. No one even carries 5-speed V8's on the lot. I do think 4.7L 5-speed make for a better mild race truck, due to it's lighter weight and 5-speed. But for a stock or heavy modified truck, the R/T is the way to go.
What's up with the put up or shut up crap? I never said, your truck couldn't run 14's. Hell, add some mods, throw on some slicks and drops that clutch at high rpm's and you should get some good times for a truck. Not saying it's going to last. Who say's that I can't get my R/T to beat 4.7L Ha. I had my 2000 S40 1.9L AUTO! Turbo running high 13's with only 1k in mods. Started out as a low 16.3 second car stock. I got almost three times the Cubes now and 1.2 second faster to work with now.

Can you imagin what would happen if you somehow got a 5 speed on a 5.9 and reved it to 4000 and droped it. Holy sh** the metel would fly. You guys are compairing 5 speeds to autos and the R/T autos are still winning. And you are making fun of the engine. The 5.9 would kill you if it had a manual. If you want to compair engines take a 5.9 quad cab and a 4.7 quad cab both auto and race them.

It's interesting to watch a bulletin board such as this where people think that anyone really cares if they whip out their little johnson and measure it against someone else's.
As far as I'm concerned, the 5.9L R/T package and the 4.7L engines are two completely different trucks when it comes to stock performance. Automatic transmission aside, the cost vs. value of the R/T package is unparalleled in such a vehicle - It's got looks and performance all wrapped into one fun truck.
Anyone can toss money at a vehicle and its engine to make it go faster. Trying to say that one model is 'capable' of being faster than another is complete stupidity - You can always modify it further with more cash, though typically the bigger engines require fewer parts to get higher power due to displacement.
Here's an interesting trivia tidbit - Indy cars/formula racers have 700-1500hp, yet almost none are over 2 liters in displacement. (most racers such as these use 1.4 liter engines) A 2L -naturally aspirated- Oldsmobile engine was built with 1000hp, that runs off normal racing gasoline and uses no nitrous.
If you want a truck that's got plenty of balls and a great look right off the showroom floor and don't mind having an automatic transmission for daily driving, buy the R/T. If you absolutely must have a 5-speed transmission, buy the 4.7L and add the parts to emulate the R/T's looks and performance. Any crying about how fast or slow you are needs to be directed at your wallet and not someone else's vehicle, because the only thing that's slowing yourself down is your bank account.

I go to the track just about every friday night. I know exactly how the 4.7 vs 5.9 battle goes.
We need to go over a few generalizations first......more or less - points of reference.
Regardless of engine, for drag-racing at the track or in a contest of acceleration.....these should apply:
1). RCs are lighter and usually quicker than CCs (rumored to be 2 tenths difference)
2). CCs are lighter and usually quicker than QCs (rumored to be 3 tenths difference)
3). 2wds are lighter and usually quicker than 4wds (rumored to be a full second)
4). The Sure-Grip or limited slip rearend is usually quicker than an open rearend (5 tenths on some tracks)
5). Generally, 3.92 gears are quicker than 3.55s, 3.23, 3.08s or2.73s (1-2 tenths between steps?)
6). Manual transmissions have less parasitic drag and are generally quicker than automatics (2-3 tenths)
7). Stock hp for the 5.9 in the R/T is 250*
8). Stock hp for the 5.9 in a QC is 245*
9). Stock hp for the 4.7 is 235*
* (The common rule of thumb is 1-tenth second for each 10 hp change.)
Now the question is - how much of difference do you expect to see? There is only a 10-15 hp difference between engines. A simple difference of only 15 hp isn't even good for 2 whole tenths! How much of a difference in performance do these other variables make? It's all about the "package". If you want to compare the 4.7 vs the R/T, you should at least create a comparable package. If you keep a totally level playing field, (same cab, same trans, no mods) the 5.9 comes out on top. Once you start to mix and match between transmissions or cabs, the results start to get all messed up. Once you start modding either engine, the results will be further complicated.
I've added the (tenths) difference at the end of each item. These are my guesstimations and will certainly be debated by some...... But the point is that there is a performance difference between cabs, transmissions and gears. Everybody seems to throw these differences out the window when they are trying to make their arguments. I just wanted to bring them up, because I know how important they are in the "performance package".

Hey Matt,
Nice dyno pull, what times where you running with 208hp@4750 280@3250? I don't know what up with that 2000 R/T but dam it had no Torque!
I pulled a 208hp@4000 303tq@3600! I have a 2001 RC R/T. I dyno it at 4400 miles on the motor. Still needs to break in fully.
It's hp pull was from 3900-4400 within 5hp range Avg of 200hp. Without a Intake system it ranged 10hp more in some place with an avg of 7hp threw out the band and held it hp band 200 rpm higher.

Hey sun city,
You are correct. But the 4.7 guys have such blinders on that they don't listen. I proved that point on a ricer post. If I had a CAR I would go with the honda accord. Did I say car. I think I did that whole time.
4.7 CC 4x4 5speed 3.90 lsd

If you guys want to get to get serious about performance you should read the following book.
{Max Boost, Author: Corky Bell} ISBN # 0-8376-0160-6
You might also want to review the old Bosch fuel injection & engine management system manuals.They do a good job of explain how the make all of the fuel injection componets work together. It will help you to understand how to trick your system.
I just read about a stock Miata 1.8 liter engine with alot of boost pressure putting out 400 Hp to the rear wheels. It is a daily driver and runs beteen 8 sec.-10 sec 1/4 depending on venue and weather and the driver.This is with street legal tires and pump gas. These are sanctioned events. It is in this months Turbo magazine. So if a 1.8 can rear wheel dyno at 400hp with a modified T3/T4 turbo with stock internals then that tells you how potential your 4.7 has. The thing is you will have to design and tune your own system and fabricate some of your own parts. I guess you can buy this type of work but it get expensive in a hurry.Before I started for Gm I did this type of work.This type of work is not hard you just have to be able to do highschool math(basic algerbra) and be able to follow directions. It helps if you know how to weld and machine aluminum and steel.

Hey Anthony,
I did a couple of dyno pulls with my 4.7 a couple of weeks ago.
I ended up with 233.1 hp and 313.0 lbs-ft torque at the rear wheels. That's basically with just a PCM and throttle body. Neither the hp or torque were particularly peaky.... about what you would expect from a "truck" engine.

My truck has run a best of 14.63 @ 93.3 mph with my stock street tires (2.178 60' time). I hope to improve on that quite a bit once the temps get back down to a decent level. I'm sure a set of slicks will improve things in the 60' area!
I am planning a turbo install on my truck in the very near future. Then we'll see what kind of numbers I can come up with.
