boss intake

[grabberblue50]

so I am thinking about buying a boss intake. I already have a jlt cold air headers bbk shorties and muffles with sct 93 octane tune. will the tune I have support the intake or should I buy the latemodelrestoration set up that comes with a tune? also does anyone know if trickflow or bbk plan on make a intake for the 5.0 anytime soon?

[Rebelracer568]

I have boss intake. I personally like it. I make more hp but I didnt gain really any torque from it. I have almost same mods as you

[grabberblue50]

what tune are you using

[jng2985]

what tune are you using

not just get after a dyno tune after the install?

[Midnight11]

i like mine. did lts too to offset the tq loss

[BLK2012GT]

I would do a cobra jet if I did it all over again.

[grabberblue50]

boss intake requires different cold air and throttle body

[grabberblue50]

sorry I mean cobra jet intake

[grabberblue50]

what about other intakes like bbk trick flow etc any info on that

[grabberblue50]

I find it hard to believe no one besides ford has made a intake for the 5.0 engine

[re-rx7]

I'd do stock intake. Lol

[Toby]

MMR makes a bad ass sheet metal intake for the 5.0. I am personally not a fan of the boss intake for a bolt on car.

[03MachMe]

I want a boss intake mostly because I like the look. Plus would be helpful with autocross

[Rebelracer568]

what tune are you using

I had my car dyno tuned by gear heads. I was running a bama tune with no issues

this!

This debate will go on for years. It's all preference with the Boss vs. Stock. Some love it and some hate it. IMO, it wasn't worth the torque loss, so I went back with the stock intake. If you run the Boss, you'll see your big gains at 7700-7800 RPM's which is where it really shines. I couldn't bear the thought of spinning my motor that high just for an intake. But, a lot of guys don't mind...like Brent Yager.

Thats the exact way I feel.

Ditto. This is a Mustang not a Honda. The boss was designed for high-revs and has the "hardware" to support it. Lol.

[TrueStreetTim]

We just tuned a BOSS intake to a 5.0 (no headers) car yesterday. Picked up 7hp & lost 15tq. We're moving forward with porting the Intake to measure gains today.

[re-rx7]

How about throught the curve?

[Dark Pony]

My car with the Boss IM and no headers at the time netted me 13 HP and lost 22 FT LBS

[TrueStreetTim]

How about throught the curve?

Will be posting all the info soon!

[Oxford14Stang]

Stock manifold FTW

I agree with you. Spinning a stock valve train like that for extended periods is just asking for trouble.

I love cock

So I've heard.

[JDMLOL]

Lol.

[Oxford14Stang]

Lol

[Midnight11]

if its good enough for a boss must be good enough for just a 5.0 ;)

[Oxford14Stang]

if its good enough for a boss must be good enough for just a 5.0 ;)

I love you(no homo) so don't think I'm being a dick lol but arnt the boss' redline higher? And I know the internals are built for higher revs

[Yagermeister]

Boss intake here and 32,000 miles and no issues shifting the auto at 7750-7800. If you shift any lower you are wasting the Boss intake. You also need to gear it properly to match the goals of your car.

[Oxford14Stang]

Oh boy. I just can't do it man.. no doubt these 5.0s are tuff, I just got bad luck lol. If anyone is willing to run them that high there's no comparison. More power to you brotha! 32k on yours and no problems reassures me how much of a beating they can take. You need to post that around more often :)

[Yagermeister]

150-175 passes in the car at the track and a few road racing events too ;)

[pohnjarker]

i liked my boss intake when i had it, i say if you stay NA, go for it.

i didnt notice any tq loss down low and seemed to not stop pulling up top until switching gears. even with my booboo manual tranny, it was all good. maybe i got one of the good ones!!

[Dan12GT]

I want to see what a dyno tune will get me before I go boss. Losing up to 15+ ft/lbs and only gaining half that in HP between 7500-7800 is silly to me. You are in the 7500-7800 rpms for less than half a second. Don't see where 7hp more up there will do any good. I am interested to see the curve gains from Tim though. That's what really counts.

[grabberblue50]

thanks

[grabberblue50]

thanks everyone for info

[03MachMe]

There is a reason why they put them on the road cars (boss and boss ls) and not the drag car (CJ). Danny your right your only in that RPM range for a short time in a drag race but you could be in that RPM range for a good amount of time on a road course. If anyone doesn't want theirs I'll take it off thier hands lol

[grabberblue50]

how did you get a picture to pop up when you post

[Yagermeister]

Actually the CJ has an intake very similar to the Boss but moves the rpm range even higher

[03MachMe]

Exactly so you can be in the power band longer due to not staying in an RPM range as a road car would.

[Yagermeister]

From what I've heard is that the CJ intake didn't extend it but rather moved it so if the Boss was 5400-7800, the CJ is 5700- 8100 now.

Hmm either way I'm sure the engineers at Ford are a lot smarter than I and know what would be best lol.

That would scare the shit out of me holding 7500+ rpms for more than a second or 2. My point was tailored to drag racing. I can definitely understanding holding higher RPMS much much longer in road racing scenarios but still scares me, when I see that gauge go red I shift!

Isn't there something with the engine that will shut down the motor or starts triggering knock if its held at 7k+ for more than 10 seconds? I might be speaking out of my ass at that one. Just something I thought I heard.

[Yagermeister]

There is a setting in the tune (10 second item you mentioned) from Ford that is easily bypassed in the tune. Make sure your tuner changes this no matter what you do to your car.

If you shift when you see red, than the Boss IM isn't for you. Exactly why I got rid of mine. It makes me cringe when I hear the motor spin that high. That's just me though. Plus, with the MT82...it doesn't like to be shifted that high. Remote shifting transmissions are prone to gear lock outs at high RPMs.

Ya no intentions from me to get it at this time.

doesnt the Boss 302 come with the same MT82?

[03MachMe]

doesnt the Boss 302 come with the same MT82?

Yep

[Dark Pony]

And the Boss has the same issues. Believe it or not, the GT500 has the same issues with the TR6060. A lot of it has to do with the remote shifting.

[re-rx7]

stiffer motor mounts.

[BLK2012GT]

Hmmmmmm don't have any problem with mine shifting at 8k rpms and before my build I was shifting at 7700 rpms.

Thats weird cause neither do I.

[KungFuHamster]

Remote shifting transmissions are prone to gear lock outs at high RPMs.
Can you give more information on this and how this applies to remote shifting vice a regular tranny?

[Midnight11]

Shifting over 7500 ftw!

[Dark Pony]

Everyone is not going to have the problem foos, but gear lockout is very common with remote shift transmissions.

Essentially, a remote shift transmission such as the MT82 and TR6060, are operated by shifter linkage outside the tail housing. The shifting mechanisms inside the transmission differ from a direct shift like a T56.

Direct shift transmissions such as the T56 have a fully enclosed tail shaft providing much more solidity and a "direct shift" from gear to gear. Again, the shifter mechanism is different.

The actual gear structure from a TR6060 and T56 are the same, but the way it's shifted is different. With a less supportive shifting mechanism, you are more prone to gear lockout at higher RPM's.

[Oxford14Stang]

Everyone is saying HP gains of 7 w/ boss intake? I was under the impression that the boss intakes gave you upwards of 40ish? But sacrificed tq? Only thing I can think of is someone who has all bolt ons but uses the stock intake manifold post dyno #s or better yet track times and someone else do the same but who has a boss intake on their car.... we have any two people with the same mods other than intakes?

[Toby]

We just finished up doing some testing with a boss intake ported and unported. Results to follow but I will say that apples for apples nothing but a stock boss intake and a corrected tune you gaine around 5 hp up top but loose as much as 20 ft lbs down low. Now ported boss is another story...

Also we plan to do some testing with the stock intake ported and not. Keep your eyes peeled for the results!

[re-rx7]

Ported stock im could be interesting.

[DirtyD]

I may be interested in ported stock as well

[Dan12GT]

Ditto! TS can use my car as a test bench! :)

same here, if they need a boosted car to test on, i'll be happy to leave mine there with them while im away :happy160:

NO! Mine! Lol

[BV600]

Little late on this. I wouldnt do a Boss Mani. Ive had one and didnt like the loss down low but loved taking it past 7500 especially with the procharger.

With my C5Z I raced a 5.0 with AED Tune, Lts, Stock manifold, Maybe CAI. Had a hard time beating him down low I would say it was dead even until maybe 110ish and I would slowly pull on him.

Then raced a 5.0 with BBR Tune, Lts, Boss Mani, Steeda CAI, 3.73s and was walking it hard.

Both races where from 20-40 Rolls. Could have been the tunes being different?
Also The races against the no boss 5.0 I was on 91 oct instead of 93 which I was tuned for.

[Mrjeremyt]

Definitely would like to see a ported stock.

[BV600]

I've got an extra for sale.

[Mrjeremyt]

Do you have any specs as to the gains? Simple logic says more fuel, air means more power, but its gotta be worth the price. Lol

NO Idea but its just an extra one for porting if someone wants to buy it and find out

[TrueStreetMotorSports.com]

Hey guys and girls, We are working on a write up of what was done to make the boss perform. We are seeing some real nice gains with the True Street Ported boss. Over the stock intake as much as 35RWHP and 25rwtq in the upper range of the RPMS. I am working on the write up and will post dyno sheets to show our testing and what we have found. Stay tuned :head3:

This is something we will be looking into very soon, right now we have been working on perfecting the boss intake and making it preform as good as it can. We have done testing on built N/A motors and seen gains and on this latest port it was on a stock car with a off road mid pipe only. Lots of calls about this and we will be looking to move forward with orders and port work in the weeks to come.

[Mrjeremyt]

Look forward to seeing the results. Im assuming you would have to re tune the car as well? Specialty jobs like porting and tuning are about all i would even consider paying for. I prefer to turn the wrenches on my own stuff. Lol.

With the testing we have done it does not require a retune to make power, BUTTT....... there is some room for improvement with tuning/timing and the porting job.

[Mrjeremyt]

Sounds good, probably end up doing more if a retune is obvious for proper gains. 24lb injectors and a 90mm throttle body maybe? Even a one off intake thats wide enough to really pull out the power of the larger intake.

U mean 47lb Injectors right

[Mrjeremyt]

I havent done much research into it. I was just grabbing a number out of the air that wasnt too extreme. Car comes with 19lb so i figured a slight bump would help. Mine is a daily so id like to keep some fuel mileage. Lol

[Midnight11]

I'm pretty sure our car comes with 32lb

[Yagermeister]

Midnight11 is correct in that the new coyotes come with 32lb injectors

[Mrjeremyt]

Wow, I was way off. I'm gonna go sit in the Dunce corner for a bit. lol:emotions122:

My old 4.2L V6 came with 19#. :lol:

[Mrjeremyt]

Damn I dunno where i got that number from... lol. Sounds worse the more its repeated. Haha

[TrueStreetMotorSports.com]

The old fox body 5.0 mustangs came with 19# injectors.

[G-Mann]

I really like the boss intake. I put down 422rwhp and 388rwtq sae on a hot summer day. I got a really good tune and felt like I lost nothing down low but got that something up high I did not have before. I shift at 7500 rpms so I do leave some on the table but the way the car pulls in the upper band was the icing on the cake for me , I just try not to abuse it. Outside of test runs in the 6 mths I've had it I only had to put it to the test once on a srt 392 that was showing his ass. The Boss intake sent a clear message to the SRT 392. Forget about it.

[HAM711]

I just put one on, i have an auto 2014 and i got a bama tune. I am impressed with the intake and tune. Rolls out slower but at 3500 rpm it knocks you back. It shifts at 7300 vs 6700 with the stock intake and a jms tune.

Need more RPM. Have them set your shift points at 7,600.

I ran 7,300 with the stock intake.

You know you can always contact the great people at Ford Racing to get the proper answer to that question and they sell that beast. I am hoping to afford that sick cobra jet setup before long for my 13' GT.
