I know its been discussed but how much of a performance gain will my truck see from doin these simple mods to help air flow? Its a 01 silverado z71 with a volant cai and bullydog power pup on it already but i'm lookin to get a lil more out of it.

 

when I did it to my other suburban I did not think I got that much out of it. for the amount it cost I would not do it again. Also the 5.3 if you have looked have a tube like design to it, even though it is still a manifold.

 

I would be surprised if you feel much difference if any.

 

The other thing is you talk about all the things you want to add. They would give you more power. not sure how much, but could be very little. those type of things would work better and give you more, but would make better and more power on a high peformance motor, and not so much a stock one. I want to point out when you add all this little stuff on to try and get more power,and add up the cost, in the end you could have not got any of that stuff and put a little more money with it and done somthing really cool and give you more of what you where looking for. I did so much with my last suburban and still did not have what I wanted, so this time I did it right, and got what I wanted. best part is I am still not done.

 

so should i just save my money and do the electric fan conversion kit?

 

A lot of people seem to like the fan conversion and have said they felt power gains. I could not tell if I gained any power or not.

 

but with all the stuff you've done to your truck you shouldn't be able to feel it like it would...at least i wouldn't think since all i've done was the cai and the programmer

 

I did not feel the gain in power from the fans becuase of all the other stuff done, like you said. but I have herd nothing but good about putting them on and getting more power. It really don't cost much to do, unless you get the nice flex-fan kit. what I used for my truck only cost about $250 or so.

 

where'd you order your's from? Because like i said i want a little more power and i hear they do help with mpgs

 

i believe the 05+ E-fans will fit on a 01. first place i would go is a wrecking yard. make sure you get all of the harness. if not BlackBear sells then, and get a real tune from him also..

good luck
