 Subject: 4.7L Billet Throttle Body - Dyno Sheet
IP: Logged
Message:
Well, I finally got the Dyno sheet from the 4.7L tester...
Please keep in mind that there are NO other modifications with the exception of the Billet 68mm Throttle Body:
MaxPower = 218.3RWHP
MaxTorque = 272.9RWTQ
Add about 24% for driveline loss (automatic) and you've got some decent HP gains from the TB alone.
Hey Bob...time for you to upgrade the TB. The exhaust system (which was also tested as a one-off) only showed a 1.3-3HP increase.

Bernd are you saying the billet throttle body alone gave an increase of 218 x 1.24 = 270 hp from 235 hp stock??

The tester emailed me back and it was the Billet TB with a open element K&N. But yes...the Billet TB was the major player in the HP increase. Remember, the test vehicle was a 2000 Model with the stock 65mm TB. The Billet TB was 68mm with a "Velocity Stack" style opening.
The exhaust was, from what I got from him, a Dynomax system. (That's basically an R/T system from a '98.)

I am running the Airaid intake and a custom 3 inch exhaust on a otherwise stock 2000 Sport 4.7L w/ a 5spd. It kills most cars and trucks. But of course I am still looking for more power. I am nervous about throttle bodies just because I dont know much about them. Where could I get one of these, and what concerns are there? Any tips on installing them, and what changes will occur would be greatly appreciated. Thanks -Jon

I own a 4.7 and have a magnum performance throttle body. It is supposed to be the best jules could come up with. It is built on a 65mm throttle body ,tefloned and has been bored out all the way but the butterfly is still 65mm. Have you or your sources conducted any tests on such a piece. How does it compare to the billet.

Still trying to find them (no response from the user) but on the 65mm ported TB, something to consider. The ported 68mm TB's make a very noticeable performance increase...why stick with a 65mm when you get more out of a 68mm for less? (I know how Jules likes charging a lot for his TB's....i've got a $1000 TB sitting on my workbench...my Billet 48mm works much better.)

Well, it sounds like that TB makes a good differnce. So far, my 98 5.2 is stock. Still trying to get some spending money for my first mod. I was pretty sure it would be an intake, but it sounds like the TB will give me the best power increase. Bernd, what would you recommend as my first upgrade? Also, what Throttle Body would you recommend for my 5.2? Thanks

That would depend on your budget. If you want a good throttle body, the F&B Billet 50mm is an excellent choice (getting ready to test a 48mm Billet on a '95 5.2L SLT this weekend as well). Cost, about $450 (from the flometrics website): http://www.flometrics.com/TBhomepage.html.
Or...you can order a QuickD Throttle body: http://www.quickd.com
Either one is a good step above the factory TB.

Hey bernd thanks for all the reach and facts.I read up on the 4.7 and it said that the stock TP flowed about 600 cfm,know that sounds like a pretty good drink of gas for a 287 cu in street engine.I remember[yes I can remember that fare back] when I had my 1966 mustang 289 and added a 600 cfm carb,that was as big as you would want to go on a stock 289,any thing bigger was over kill,it would be running so rich that ever time you got on it,it would blow black smoke out the twice pipes.My question is..With a 68mm TP would it pass emissions?And would it stink of rich gas smell? The EPA is talking about making mandatory exhaust ck's in Toledo Ohio again.

Bob, you're using a carbureted engine comparison vs. a FI engine. There is a difference. FI engine are much more capable of compensating for larger throttle bodys (to a point) than a carbureted engine. (Fuel metering/delivery is controlled better for one.)
The 68mm TB's come factory on the '01 models so warranty shouldn't be an issue. As for running richer, that's again controlled by the PCM (via the O2 sensors, IAT, MAP, and TPS sensors.

hello,
I was wondering about this throttle body I know about mustang performance and performance in general but, my girlfriend is a big Mopar fan so along with my 86 mustang we also have a 2000 Dodge Dakota Club Cab 2wd w/ a 4.7L V-8 and I never can leave well enough alone so I have already had a 3inch catback put on a jet performance module I took off the clutch fan, added 3.92 gears and put on a homemade air intake.
My times bonestock were 16.3 at around 82mph after the mods and sticky tires I am running 15.2 at around 86mph. I think according to al these messages I should be alot faster than that, so I am wondering about that throttlebody you are talking about because on a fuel injected mustang you only get maybe 10hp out of a throttle body that is 5 to 10 mm bigger. And yes I know the 4.7 is SOHC I am a Dodge heavy line Technician, but the same results are found on the 4.6 w/ a bigger throttle body around 10hp. Just would like to know where I could price these.

I have a 4.7 in my 2000 Dak' extended with an open rear and auto. I would like to throw in a powertrax rear, custom made intake as well as headers and exaust. I would like to know if there is a good duel outlet system for this application with good powerful(but not obnoxious) sound. I bought Borla headers from Truckperformance.com and they ripped me off. They did not give me the Y-pipes as claimed, plus the construction was poor compared to the JBA headers(FYI). If someone could help with the cat-back I would appreciate it. I would also like to know what throtle body you all speak of. Who makes it, where can I find it? Does anyone have 1320 times in stock trim and with mods. I know the Quad cab is worth 15.7. Responces to any of these would be much appreciated. Thanx.

Hey Bernd,
Those seem like really good numbers and the hp curve looks much flatter than the factory published dyno chart.
Does the tester have a baseline from stock? These should be some pretty impressive gains.
Guess I gotta start saving for my next mod, now! Hehehe!!
Did you get my email about matched injectors??

If the 2001 TB's are allready 68mm's what has Dodge done to this engine to keep it from producing more HP than a 65mm 2000 model. Seems stupid how hard they have tried to keep the power down on this engine.
Also I have noticed a large closed of section of the TB at the bottom. Cosidering ripping the TB off grinding and polishing it down and installing a larger butterfly valve.

Bernd, I've got a baseline dyno, 5 spd trans though. Also, Bruces Billett TB is 69mm, atleast the one I've tested. The Hughes Engines 68mm TB is pretty good, I have a Hughes engines 68mm TB on the truck right now, and I also had a Hughes engines 65mm TB, sold it to Chris Lambert. BUT, for what I payed for these Hughes TB's, it's going to be worth it to save a little extra and get one of Bruce's Billett TB's. Believe me folks,Bruces TB is the Sh?t.
BTW, the factory 68mm TB, does'nt flow much more than the factory 65mm TB, I have the numbers from Hughes around here somewhere, but I was surprised, and so was Dave Hughes, Its not really worth it Stock vs stock.

I'd say there is something up with that dyno graph. The Peak HP can't really be counted as its a spike. The rest of the curve is quite wavy as if there is a problem.
It would be interesting to have both a before and after graph on the same printout to compare where the gains are. Otherwise you could be counting a spike vs no spike.
The area under the curve is what you want to look at in reguards to the powerband.
