I have an '03 5.3 with a clutch fan. will an electric fan make any difference? or enough worth messing with?
Not for the price IMO until you get a lot more mods. Mine has the big radiator that didn't need swapped and it still cost me $800 for the efan set up to work. The only benefit I found was better idle AC operation.
OEM 05-06 fans $250
harness $100
Tune $450
Of course the tune did more than activate the fans so there is collateral benefit but doooood....
I assumed for mild mods. That it wasn't worth the effort if it came down do it I'd buy a wrecked pickup and pick it apart for what I want out of it.
Can I ask you a question? I saw in your garage that you used the stock filter box why didn't you use the whole AirAid kit? I bought the AirAid cai and the throttle body spacer I did notice I got better gas mileage but at the same time I bought ngk plugs and jba 9mm wires so I don't know if it was a combination or if I wasted my money.
I got it all for $140 from two different places (filter and tube). That $70+ savings helps cheap people like me. Plus, I modded the stock box to pull more air and the stock box is not open to the underhood heat like most cone set-ups.
I asked you before about a bbk 90mm throttle body. Is that a waste of money? and I am assuming that a Granatelli mass air flow sensor isn't worth $300 am I right?
Stock MAF is perfect for a lot of power. Once it's not, it's time for an SD tune anyway and that cuts the MAF out of the picture. Not sure how the BBK 90mm will help when the opening in the intake is not 90mm. Someone else can tell you that.
Okay. I was just curious as to what my next step will be. I will definately be getting a Nelson Tune I've known about him for a couple of years and also either sonnax or corvette servos.
I had my transmission programmed in 2006 to a 2006 supposedly. I was working for the Chevy dealership here and I bought this GMC used from them with 23,000 miles on it. I drove it around for about a week and 2nd gear was really really stiff I was afraid it was going to stick.
one more question I'm going old school on you. On my '85 i cut out some vacuum lines for the headers. I want to get rid of all the smog crap it's in the way I don't need it and I don't believe in global warming. But I want to keep the cruise control Is there any schematics or anything to show me what is what? I may is to tear it all out and start over but I figure this will save me time.
I have a 80 mm bbk and noticed a lil when i had it on my 4.8 sierra. IMO i would just port your stock tb and do a tb by pass on it and most likey get better results. Spend your money on something better. :twocents:
thanks for the advice on the bbk I was mistaken on the 90mm it is actually 80mm. how do you port it?
Impala fans run about $100 @ collision parts centers and you can get the wiring kit @ Auto Zone for about $30. That was the last bolt on I did and yes it still pulled harder.
there you go. why spend $400+ on name brands
00-03 Impala Monte Carlo Radiator Cooling Fan Assembly:eBay Motors (item 110397964576 end time Jul-02-09 14:16:12 PDT)
I got a set of z28 fans (LT1, and LS1 used same fans) out of bone yard with harness for ~100. I just used 2 relays to power them, which are switched whenever my radio is on (aka, when key is on) I put a kill switch inline so I can turn them off when I want. I honestly didn't run the fans at all over winter, and in summer only if stopped in traffic. Above 40 mph, i just shut them off.
Noticed a small gain in both gas mileage and power. Not much, but they cool A LOT better then factory. And I hated being under the hood with engine running before. Great for cooling truck when it is off (just watch battery gauge.)
I know a lot of people who just have them run whenever car is on, and never shut them off. Work fine. If motors EVER blow out, Auto zone has replacements with lifetime warranty for like 50 bucks.
yeah buy the e fans they help u alot ull see the diffrence right away!!!

You will not tell the difference at all unless you have a small motor with no mods at all. I sold some Impala fans to another member that hopefully will work great for his application. Wasn't aware there was a full "wiring kit" at a box store for $30. Mine is a worst case scenario as I do have the big radiator but don't want a hacked up deal with wire nuts :lol: (you know who you are).
Haha I agree I didn't even wire up the halos on my denali headlights I'm not cutting wires
Its worth 15+HP on a stock 5.3 depending on the clutch fans engagement. Pulled our test truck with a clutch fan several time each time the power went a little more a little more. With electric fans no load more power. WE hooked mine to turn on when the key is on.
