put an engine on top of Mount everest where its -2 to -30 Fahrenheit
put an engine down in a desert somewhere hitting 140 Fahrenheit.

One of the engines is going to make a lot more power than the other. Why? Because
HOT "Oxygen" is better than cold "Air". Do you know Why FI setups lose less power at higher altitudes? It is not from the air being colder from compression that is just a side affect of how compressing air works. the air is already cold in some locations.. It is because of the amount/flow of air that directly results in more oxygen. Temperature is but just a small factor in the grand scheme of Combustion. It will always play second fiddle to CFM. You could have "Absolute Zero" temperature air yes i know impossible... and you won't combust crap if there isn't something combustible in that air.

This is why DA and water grains are so important with racing.

Unrelated but do you have the MAF data (MAF airflow vs voltage and MAF airflow vs Period) for us HP Tuners users for your tune required intake?

Sorry, my units are engineering so you will have to make the conversion. We do not use period because it would change with different processors (ecu) and we do not use LB/min because metric is better I have no idea why most of the tuning software companies started using LB/MIN, they used KG/HR for a long time. everything else on the car is metric lol.

1 KG/HR = 0.0367437 LB/min

Would someone just go to the track and let us see what it will do then we just buy one

What's stopping you from doing that?

 

[GTHELLCAT]

did that on my hellcat they [they said 37 hp did not do it ] lost 2 mph and 1 tenth don't want to go through that again

:lol: ever think da and not back to back runs had something to do with it? Maybe you arent a consistent driver either. Too many variables. It needs to be done same day within 1-2hrs of each other with someone that is capable of being consistent. People can have autos and not be consistent.

I haven't had time to go to the track but I do feel a difference.
My buddy has a pp jlt cai, bbk throttle body, longtube headers full borla exhaust and a lund tune. He beat me by half a car and all I have is an a6 with the pmas cai, resonated delete and lund tune.

Your buddy needs a driver mod. Unfortunately that proves nothing.


With that said i fully believe Pmas intake fulfills what Nick (Pmas) says it does. I have zero reason to doubt him.

it was the same day

 

[15dib]

It does prove something to me because before he went longtubes and I got the pmas he would take me by almost half a car. Same drivers, multiple times.

 

[mustang_guy]

You didnt address anything with the da. You mention nothing of how far of a time difference it was between runs. Da can change drastically in only a few hours. It also doesn't tell us if you're are consistent driver either. Slips, da and consistent drivers matter. I hope you understand im not just being a jerk.

It proves you gained. But it also proves your friend is not a good racer nor does it put any confidence for anyone that hes consistent either.

Thanks for clearing that up @PMAS . I've never come across so much discussion about intake temps before and never thought is was as big an issue as people all of a sudden seem to think. The worry of losing a few horsepower in stop-and-go traffic during summer heat has always had me baffled.

Most people here do not understand the myriad of information that is fed into the ECU in order to produce the maximum horsepower with the components provided. Intake temp is only a small percentage of that info, yet people seem to be treating it as the "holy grail" of variables.

My personal worry is not stop and go traffic.. but the staging lanes at the drag strip... I certainly do not want to pull up to the starting line with 135 degree IATs. With my stock airbox I am generally under 100. When you are counting tenths and hundredths of a second... IATs DO matter if they are pulling any timing at all, or preventing timing from being added.
