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

[JStang]

That's hot!

 

[2005mach1]

wow
can't wait for numbers

 

[201250]

JJ like everyone else has said THANKS for the pictures and write up so far.

 

[assasinator]

That sure don't look like its gonna make my 5 0 tow any better....

you don't have a 5.0

 

[Germeezy3]

you don't have a 5.0

Are you sure?

We had very limited time on the dyno with this car today due to a previous family function but I wanted to share the intial results.

Attached is the dyno sheets showing our best run with the stock manifold, dynatech LT's with catless mids, JLT CAI and our tuning against the same combination with the Boss 302 Intake manifold.

I know these arent the peak numbers everyone including myself were hoping for but for an initial dyno session with a new intake manifold they are very promising especially after 6500 rpms. More tuning will be done and more results are forthcoming thats for sure.

One thing you will notice more then anything else is how this manifold doesnt give up making power where the stock one falls on its face at 6500 RPMs. There is a 52hp gain at 7200rpms and thats why this combination feels like it pulls so hard, it just keeps on pulling.

I made a few changes to try and gain back some of the low to midrange torque and picked up a tad but considering that the Boss is rated 10ftlbs lower then the stock 5.0 I dont expect much of a gain with this intake when all is said and done.

I will continue to work on the calibration to try and find more midrange power and more peak power as well but so far I am incredibly impressed with how hard this car pulls and huge gains where the stock intake gives up.

Cant wait to hit the track thats for sure.

Thanks again everyone,

JJ

ive been waiting all morning for your results lol still going to hold off until you get more time w/ it though.

Somebody needs to have a heart pill ready for Matt D when he sees 52hp @ 7200. Awesome job JJ.

Now we see why the Boss sports its 7,500 rpm redline, it looks like this engine from the heads and cams was optimized for airflow in the 0 to 6500 rpm range. The gains seem to all be at elevated revs, so it sounds like a N/A build would have at least an 8000 rpm redline to take advantage of the increased airflow from heads/ intake and cams.

Thank you for you being here for the customer and not for the magazines or just to make profit! Its rare that you see a company that displays some of the qualities yours does!

EXACTLY!! and Im also trying to stay N/A.. if i could get close to 500whp on the stock shortblock, i will be EXTREMLY happy!

 

[fiveoh]

Mid range tq loss isnt worth the high rpm gain for me, I wont be getting one of these.

Thanks for the writeup! Very informative.

WOW I can't wait!!!!! My car is going to be always in the higher rpms

Trust me when I say that you dont feel that loss at all on the street, it pulls very hard in all gears and at all RPM's. The high RPM HP gain is very well worth it and you feel every extra hp above 6500 rpms.

Is there any risk to our non-boss motors running them that hard all the way to 7300rpm? We don't have the beefed up valvetrains of the Boss, right? Sorry for the noob question.

i have watched tv shows about this 5.0 motor that the Ford Designer/Engineers say the redline is 7300 for it. I have seen people rev these motors to 7500 N/A.. w/ a power adder it probably wouldnt be a good idea.. Personally Im all for 7500 rpm's for N/A

 

[RetroGT2006]

Very nice, glad to see you post up the pictures and results!! If i had a 11 i would order it now!

I've been shifting my car at 7300 ever since I got the tune from BBR. No problems at all. Several others are shifting at 7500 without any problems.

 

[brady_f]

May not be reading the graph right, but from what I am understanding, the only gains are coming after about 6600rpm's right....up until about 7300?

 

[Full_Tilt]

I suspect with more tuning we will see it making more power starting in the 5k range. But overall, thats the kind of shift in powerband I expected.

With the rod ratio of the engines it seems like we should be able to take them up to almost 8k, but there must be some other limitation I dont know about, or nobody has really tried because up until this manifold has existed there hasnt been much reason to rev that high...

Also, you guys need to look more carefully at the voluem difference within the RPm range the engine will be in while racing. Id have to do som e gearing calculations, but assuming that youre not dropping much below 4500 when shifting up at ~7500 rpm, the torque volume lost below that point means nothing.
From 4500 to 5500 the loss in volume is pretty small, and the increased volume from 5500-7500 is substantial.
And thats still with what I expect is tuning that has yet to be optimized. When they start actually increasing peak power the volume will get much, MUCH larger.

 

[Wish I Had a Nice Car]

i said 25whp+ at 7500 rpms....i was closest, i win!!!
