Performance, HP and MPG upgrades

[Ron46]

I was looking around on doing upgrades on performance and mpg, and right now I have an airdoc intake with k/n filter. I am eventually going to do pcmforless but I want to do all my other mods first before I get the tune. I was looking at doing the super sparkz spring delete with the ported throttle body. What is you guys input on these mods? As anyone done them? Also I was looking at the OTTP header too.

Don't forget ac delco iridium spark plugs!!!! Maybe also throttlebody spacer, but I'm not going to lie I also have the I5 with the tune and E-fan kit and I get 13 mpg on the streets and 15 on the highway. One more thing I have a stage 2 JETS engine chip if you want to try that out first.

I don't believe in throttle body spacers or IAT chips that fool the PCM into thinking you need more gas because of the false temp reading on the intake air..

What I have done to mine which gives me on average 20+MPG in city/interstate driving is:

K&N CAI

Gibson Cat-back Dual exhaust

PCM tune from PCMforless

Castrol Edge oil

and

Pulstar ef1i iridium spark plugs

I HATED my TBS. All it did was make a hissing noise around 2000 rpm's. I agree with Dennis except I run Mobil 1 and add the e-fan to that list.

How much the cat back run you if I may ask? I'm looking into replacing my exhaust soon.... And one quick thing... What's the difference between those plugs and the delco ones? Thank you

I got the Gibson exhaust back in Jan of 06..I paid $472.00..the Model number is GIB 312700..They sound bad ass too, if I do say so myself..

The Plustar Spark plugs are 950,000 watts more worth of spark power, than any other plug on the market which have 50 watts of peak power typical, Pulstar plugs generate up to 1 million watts of ignition power...Read the Amazon link I included..scroll down to the plug's description..After installing them, I noticed a nice improvement in idle smoothness and response in throttle.

 

[JonBishop]

Awesome thank you I'll have to check them out, I was either thinking flow master or Gibson... And I'll defiantly try out those plugs

super sparkz spring delete

I had not heard of this mod before. Did a quick search and found this

http://www.355nation.net/forum/supe...ring-delete-upgrade-prices-ordering-info.html

Interesting mod, lots of positive feedback for it, replacing the wire springs in the coil packs with a special piece of Beryllium copper wire. The thread is 28 pages deep, didn't read all of it, but all short term feedback was positive and drivers noticed smoother idle and acceleration. :huh: It's got me thinking again, this is from the same guy that does the ported throttle body.

 

[JonBishop]

So the super sparkz spring are good?.... I'm thinking bout trying it but I wanna kno if it's good tho...

 

[Ron46]

I read the whole thread and it seems like everybody has good reviews on them, I am probably going to try them out soon. I feel the same way you do. I have been thinking about doing a custom exhaust because the gibson, and magnaflow are pretty expensive. I was thinking a flowmaster 40 or 50 series and removing the resonator, maybe high flow cats too.
Also the spark plugs are worth it? I am interested in doing the spark plugs plus the super sparkz at the same time.

Remember the easiest way to increase mpg is to lighten up on the skinny pedal. I doubt you will see any measurable gain from these mods. They can still be worth doing and may help with performance (which often means using more gas) but I would recommend going in with tempered expectations in regards to mpg. (14 mpg with Gibson, airraid, ac Delco iridium which is OEM equipment, and pcmforless tune)

Ok thanks!, and I just called up about the super sparkz and I ordered a set. I will do a review on them when I receive and instal them.

I dug up my old records from back in 06..

I had my truck dyno-checked by a place here that has a 4X4 dyno machine (lot of suped up 4X4 pickups here)

And from the 3 run test, I was pushing 218 HP at the wheels..Given that the factory flywheel HP was 220 HP..It was estimated I was about at 243 HP at the flywheel...I would say the gains are appreciable with the mods I mentioned earlier in this thread.:thumbs:

For decent performance, use this:

For raw HP, use this:

And for mileage (with good performance), use this:

or this:

Don't forget tires. A lot of us have those nice big chunky MT tires that have a lot of rolling resistance that cuts mileage. I have two sets of wheels/tires. A set of Toyo open country AT for most daily driving and mild off-road, and a set of Cooper discovery STT MT tires for killer off-road or just looking bad ass. The difference is night and day on ride, noise, and mileage. Just my two cents worth...

I looked around on that colorado/canyon website. I'd be interested in any mod that is backed by a dyno sheet. but so far, i dont agree with the berkelium copper mod for a few reasons. Spark power is a function of difference in voltage potential and the dielectric breakdown constant of air. since the dielectric breakdown constant of air typically remains the same in our intake manifolds(relative temps and humidities - not really going to make a huge difference), then we can assume that changing the resistance would have an effect. the power of a spark is actually lower with a lower resistance wire/junction like the beryllium copper mod. the higher resistance the material, then by P=VI and V=IR and P=I^2R, then an INCREASE in resistance would lead to a larger voltage potential across the same gap, same dielectric constant and would produce a hotter spark. dV is the thing you want to drive here, you want as high of a resistance in the spark wires as you can in order to produce a big spark. Dont trust me? Put a voltmeter on a set of Moroso drag racing spark plug wires, and then do the same to a piece of cheap household romex cable. it doesnt look like there is a a good supercharger kit

Great info H32NV! Thanks

Got the super sparkz today. I have class now so I am going to instal them after class, and I will post a review on them after wards!

 

[H32NV]

post a before and after dyno sheet! something that will help you a little bit is adding in some hotter coils(higher voltage). I saw a set of piggy back coils(can be adapted to any ignition coil system on any engine) at the SEMA show in Vegas in 2010; this guy had this setup where he ran 8 spark plugs at normal voltage and then flipped a switch to activate an aux set of 300,000V coil packs and holy s&^t! it was a loud crackly disco light show over in his booth! I'm pretty sure he took it to far though, the hotter the arc, the faster the spark tips get eroded and lose their gapping(you are basically creating your own tig welder in your cylinder chamber). Probably makes a hot flame and maybe gets him an extra 5-7HP, but I'll bet his set has to be changed out every 700 yards!

Got the pulster efi1 spark plugs, will be putting them on Sunday

Cool..Hope you notice a difference in the smoothness of the idle once they are in..I did..

BTW..make sure thay are gapped at .042"

 

[JonBishop]

Ya I was trying to remember the gaping on them again thank you, I'll post on the after fact when there in

 

[machineguneddie]

Got the super sparks and the Pulstar Spark Plugs ordered. We'll see what they can do for my truck. Thanks for all the info guy's
