I did my mods listed below on a brand new Expy which I plan to keep for a while. I didn't get the upgrades to lay rubber all over the place but just to know that I can. I'm not a mechanic of any sort, especically dealing with new technology however, can anyone comment on whether or not these mods will affect the life of the motor?

The other thing I wanted to point out was that the Airraid seems to draw hot air from the engine compartment. I know if may not have much impact to performance but does having warm air into your motor also affect it's life?

Thanks in advance,

The mods you have made should not affect the life of your Expy. These are all considered "mild" mods. You've probably only added about 30-50hp.

The ones that may affect life are things like pulleys, gears, superchargers, nitrous, etc. These type of mods put a lot more strain on stock driveline parts. Pulleys by running the water pump and altenator at slower speeds affect cooling and electrical systems. Taller gears make the whole drivetrain run higher rpms. Superchargers and nitrous are big power adders that put a lot of strain on stock components.

Question for you Sevn,

How do you like your WMS kit? I'm thinking of sending back the Airraid because the hot air intake is bothering me. I can say one thing, the Airraid does acrry a punch to the throttle response but the hot air going in ... do you know if that would impact the mototr negatively? Does the gas mileage go down due to warmer air going into the intake?

Thanks

 

Thats a very good question you ask!

THe engine is obviously built to take a certain amount of presure, heat, HP, TQ, etc... BUT, it is a truck engine and is made to take some punishment like pulling stumps, towing heavy trailers, off roading, etc...
I should think that even a supercharger with 6-8 lbs of boost would last just as long as a stock engine??

I've seen people put superchargers in a stock vett and get well over 100K on the engine.

The more HP/TQ would effect the trans somewhat. Its only made for the application in its original configuration. Although, I've heard that the Expy 5.4 comes with a beefy trans? Might take it no prob?

I agree with Sven 100%.

Slowing down your alt and water pump will have some effect. Installing a colder thermostat will definately decrease the life of your engine.

Intake, exhaust, and chip should not effect your components one bit as far as longevity.

I would think that the components effected mostly would be the bottom end? (pistons, crank, bearings...) An extra 50HP/50 ft/lb TQ would place more stress, but I'll bet those components are built to take WAY more than the stock HP and TQ.

 

Here's the link to my comments on the WMS tube. I do like it and do recommend it. I had a couple of issues during the install, but a little light weight oil would probably eliminate the fit problems with the grommets. It took less than a hour to install.

I'm not sure how or if air temp affects fuel mileage.
