I know all those who spend hundreds on their Air raids and K and N's wont agree but I believe after looking around and thinking real hard, that what we all want can be our. Its actually right in frt of our faces.

1st off I do have an air raid jr ( replaced the factor octopus) I also have a drop in K and N. Well heres the silly part. Have you ever really looked at the factory air box ? On my 04 burb it pulls air from the fender directly from the outside with no chance of engine heat getting in and affecting it. 2nd its a closed system completely isolated from the engine. 3rd, have you ever looked at all those open air type ( so called cold air systems) they all pull air from the hot engine compartment. Maybe GM with their engineers really know what they are doing. So change the tube, change the air filter to your choice ( but please rethink the air box ) factory is perfect. sure it doesnt look cool, but is that what we really want, looks or performance ?

That always bugged me... Why do people spend over $300 on "cold" air intakes when they might as well just be running a $40 open element filter? Whatever, it's not my money...

The K&N FIPKII I have is pretty nice. The new box is open on the top and has a gasket to seal to the hood so there is no hot air going in from the engine. Of course, I installed ceremic coated headers so the heat is cut down anyway.

and the throttle body is the bottle neck not the intake

 

Anyone out there swap in a large throttle body? If so, what were the results?

 

My next upgrade for performance that I'm planning is a tune. Seems like the best bang for the buck.

I think the only reason i would change the stock airbox on my 97 z71 is if i picked up one of those goodhoods with the working ram air scoop. Then i would just pick up the ram air kit that goes with it.

Over $400 for an 80mm BBK throttle body claiming an additional 8HP... No Thanks.

I have not measured it all out yet, Cold as he** out currently ! But thats all you need to do is figure bends pipe length inner diameters ..

 

From what I can guess by looking at parts I am thinking a cold air tube with filter for under $100 that would work as good as ant $300+ kit !

The OEM throttle body is not a bottle neck its plenty big infact its big enough to support the 8.1L as long as its stock displacement.

Try a custom tune for your best bang for your bucks.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
