Boss 302 Intake has arrived. Fitment and dyno coming!!!!

[Full_Tilt]

Just an FYI guys.

7800 RPM is the max these things will rev too. There is a hard coded limiter @7800. This is direct from ford racings mouth.

We tried to get around and no luck. so i dont think anyone has to worry about going to 8000

*facepalm*

Codes are meant to be broken.

I'm sure that will get figured out and fixed soon enough.

I'll check on a few things and get back.

I know there are ways around fuel flow limits on 03-04 cobra ECU's but I'm not sure about getting around a limitation in RPM in an ECU code. Unless you are going to rewire the car and somehow trick the ECU into thinking the motor is turning over half as fast as it is and then somehow still get the ECU to function properly, I don't know how else to go about it. Then again, my name isn't Jerry W either.

7800 is plenty! I haven't done the math, but, I'm sure that piston speeds have to be getting up there at around 8Krpm.

 

[JDM74]

I wonder if the tables in the ECU that are RPM dependent end at 7800. I know the LS1 PCM tables end at 8K RPM and that is an issue if you want to spin the motor faster than that.

BREAK THE CODE!!!

its not going to happen. Its similar to the 3v stuff, we had to go to a big stuff to get over 7800 rpm.

 

[Wicked97]

It probably has more to do with the ECU programmers and engineers programming not taking into account for that much higher of a rev limit because it was not a part of the design parameters given to them.

i think you hit it the nail on the head!

 

[28.]

That is a good start. Also make sure you have the correct valve springs. Floating valves at 8K will = a pile of useless parts.

This.. I can see alot of folks thinking they can bolt up this intake and expect an instant great change.. It just doesn't work like that. To get it's full benefits other parts will need to follow.. What I will say is that considering the power curve it provides and the surge up top, is that this intake will work great with centrifucal blowers like a Vortech or Paxton..Mmm.

That is correct. We tried on my 3V to rev it over 7700 rpm to see when the car would quit making power and never could get it over 7700 rpm. Even setting the rev limiter to 8000 rpm which basically turned it off it would still shut the car down at 7700 rpm. We were running the KB at 21 psi so we didn't try it much but Justin@JPC said the only way to go higher was with a BS3. We ended up leaving it at 7500 and I worked fine with the 4.10's as I was crossing the line at 7200 rpm.

I have talked to Ford Racing and they said there was nothing that could be done with the Factory ECU to make it rev any higher as the tables wouldn't support it in the tune.

Other vehicles have hard coded limits that we have made adjustable in the past so I doubt its impossible. Maybe with Diablo it is but we have done it before using SCT. SCT is looking into this as we speak and will work on a fix.

Never say never....

I'll let you know how it turns out.

I want to see some gains on a centri blown car as well

Who knows, I remember reading how these motors couldn't handle any boost not that long ago. It seems we are finding out more and more everyday. Plus just like the SHO neither Diablo or SCT has opened up the entire ECU yet for the 5.0. I have to agree with JJ about never saying never. You may prove to be right but we are so early into this motor to say anything is impossible right now.

Guys, when SCT, Diablo, or anyone else "tunes" and ECU. All they are really doing is changing the values in the xy tables for many different variables that are used to calculate the outputs of the ECU for fuel, spark, timing, etc.

What none of these companies can do is to add colums and rows to those tables. They are hard set limits that would require the very source code that the software is programmed with. I can all but gaurantee that the engineers that created that code aren't giving that up any time soon.

It is a real bummer that the factory ECU cannot run faster than 7800rpm as with the right internals and valvetrain this motor looks to be able really scream at 8000+ with just a little more cam and some mild head work.

Yes you can add to the tables. You can take a car that was N/A, put a supercharger on it and then renormalize the load table so it can calculate more load then the original calibration. Even if the data cant be displayed as a value in the software you can still change the hard code if you know what your doing and can gain access to it.

Interesting.

In regards to the fitment issues of the CAI's that curve, has anyone tried using the WMS "Ram-Air" piece that is straight on?

I think a better question is... Has anybody at all besides WMS tried one of these? I don't think I've seen one 5.0 owner list one in their sig.

 

[Mikes5.0]

When I searched this forum for that intake I didn't see any good comments. lol

I'd be willing to try one if they sent it to me for testing.
