Intake manifold

[rkhahn182]

Hi im new and just learning how to tune, I am looking for any help I can get. I currently just install a Holley intake manifold and larger throttle body, I was wondering if anyone could point me in the direction of what I may need to adjust or look out for to compensate for the better air flow. I have tried searching but have come up blank

Need a little more Info, What year car/Truck , what CID are you dealing with ? 5.7 , 6.4, stroked 5.7 ? stroked 6.4 . Which Holley? Hi-Ram, Sniper Race, Sniper , what TB

Each G3 hemi reacts a differently with the Holley, Standard sniper only pulls to 68-6900, the HI ram with two TB on the Dual 4bbl top will pull enough RPM to surpass all OEM ECUs and 90% of G3 builders best builds.

We have a customer who runs a pair of Granatelli 105's on a Hiram Dual 4bbl top on a 441CI g3 in a 2014 Challenger. 6sp...., finished up 426ci with a Hi ram and 90mm tb in an 07 QCram.....Many options...many different combos.

I have an 18 challenger 6.4, Im running the Holley sniper intake manifold with a 95mm Granatelli throttle body. Thanks for any help

Increase Manifold Volume to 14L , The Sniper intake is not known for its low end power, so you'll need to bump up some PT spark and some WOT spark,


these two attachments were spark tables we used for a Sniper on a 16 scat pak Challenger with a hellcat TB , increase knock sensors sensitivity ,

I create a graph , Knock voltage , RPM Vs Map(or pressure ratio, Air charge) which ever you log,


Attachment KR is a Knock Retard graph , it's RPM vs MAP , it's from a 2008 Charger with a 440CI with a Drag pak, Hell cat TB, basicly what i'll do is adjust timing tables according to knock retard .

As for Air flow.....I'm a believer in every thing below .71v needs to be increased by 10-15% while everything above 1ish v needs to be reduced by 20% to start.
there's a few good threads on it , this is a great onehttps://forum.hptuners.com/showthread.php?62333-Bigger-Throttle-Body

My 468 turn close to 7700 RPMs makes just under 780HP and my Airflow table @ 3.90V is set to 695G/s. Using a Modified Hi ram with a Ken Bell Big mouth TB ...point is BIGGER Airflow #s are not always better.

HELLO, I could help you with the tuning of se challenger, you have to change several things in the air flow due to the change of the intake manifold and the TB, you also have to modify the timing tables a bit and I will leave you my contact below so that Contact me by phone number and let's improve the power of that challenger, you just have to be careful, the 6.4 engines tend to be a bit delicate and due to minimal errors, people who don't know what they are doing in the programming also break.
