Manifold and intake testing <> stock-ported-Boss w/stock vs CAI intake

[Mr. Mach-ete]

My 5.0 is going in Tuesday to JPC for a Boss manifold, throttle body upgrade, cooks long tubes, 3 inch catless X, barton shifter, motor mounts, shifter cable upgrade, dyno tune.

Currently I'm sporting JLT CAI, stock manifold, stock TB, stock exhaust manifold, BBK cat deletes, stock H, JPC over axle pipes, JPC stainless race mufflers, JPC canned catless tune. I'll ask Tommy to do a before and after dyno run to compare the difference in performance upgrades.

Subbed.

agreed! I need to se the outcome as well. Been on the fence about a tb/boss im for a few weeks now.

^ +1

ALL graphs up on first page! i can go select areas or compare any graphs if someone once to see any other overlays, areas of loss, or comparison.

 

[Ratinacage]

Less than a 3hp gain over the stock IM with the Airaid.

Which graph are you comparing/looking at?

 

[steveofiveo]

Did you adjust the tune for the Boss to stock intake swap ?

What was the AFR on all runs ? where they close ?

Did you use the same air intake on all runs ? I thought the air intake could not be swapped between intakes ?


I forgot to say it earlier GREAT JOB ! ! !

thx

Shows pretty much what we've known all along. The Boss IM shines from 65-7500. The tq loss is huge though through the bottom end and mid-range. The Boss is really a track only mod. If you only plan on going to the track once or twice a year, you'll hate the Boss during everyday street use.

Thanks great info guess I will pass on the boss IM

Thanks! The AFR's stayed steddy 12.4-5 throughout all the runs. AFR's got logged as well as coolant temp, air temp, and total timing to make sure all runs were as equal as possible.

All the manifold and intake setup's got listed in the graphs, but i just added headers to explain what each one was.

Ya, we knew the boss would have tq lose down low and gains up top, but wanted to do it so that it could be a closer gain from same dyno's, same day, within hours apart and all the factors like weather would be the same.

Ya, when looking at the TQ loss down low, it is a heavy blow. The car really only shines after 6500 with the boss IM.

 

[Need4Speed03]

Was the tune tweeked for the Boss IM? If not, its not a great comparison as the tune need to be tweeked and the cam timing adjusted for minimal torque loss and maximum hp gains.

Regardless, nice work! I had a stock intake that I ported and I didnt notice a difference at all besides the whistle I heard.

BTW great job thanks

No, nothing was tweaked on cam timing side. Im sure all the manifolds could of been tweaked to gain some more power, but wanted to demonstrate a bolt on no tune gain or loss. If if wasn't so late, i would of went in and did some cam timing, but finished up the runs around 8pm and called it a night.

Thanks :beer:

 

[VETTEHUNTER]

Thanks for taking the time to do this!

Yes....thank you for doing this! Same dyno, same day testing is hard to argue with!

 

[01bluesnake]

No problem, was a fun day.

Also added Boss VS Ported VS Stock manifold graph with ARF log to first page

 

[MikeLTDLX]

No tune changes for anything? That has to have an impact on the results.

Great job

So the cold air is worth roughly 6 hp/torque. If you need every bit of h.p and can find one cheap I guess it's ok.
