Hi all,
I have been reading about intakes and I have learned that sometimes there can be a loss of power if not properly tuned. I was wondering if there are any dynosheets out there that show how much power can actually be lost with an untuned intake install. I have seen plenty with how much power can be gained and they also seem the only ones I can find. I ask because I installed an intake and I have yet to get it tuned. But I can notice my car is not getting the same kick as before. Thanks for your help.

 

Alot of people are going to tell you to search. Yes there are dynosheets out there I believe. Try searching for the case studys Al has put out I think he may have some if I'm not mistaken.

 

I could use my dynosheet as an example if you would like. I will scan it in, but I have more than just an intake. It shows the difference before and after being tuned. I gained almost 75whp

 

Yeah I know. I found a bunch of dynosheets that showed how HP an intake gains. But Im looking for dynosheets that would show how much HP you would lose with an untuned intake. THanks.

 

Here is one where you can see what it does to your AFR if untuned:

 

ROFL.
