Last week I did the Z-tube install with the Stillen. Thanks to SweetFX. On Friday, took it to dealer for the 22K maintenance.
Saturday night, time for the road test heading to Philly. Driving Night Time with a buddy. NJ turnpike wide open. First I have to tell you that I have gained a 3MPG increase aloong with quicker acceleration. Cruising at 100mph was good now time for the limit. Put in manumatic, downshift to 3rd and step on it. :twisted: Now @115mph, close to red line. shift to 4th, :razz: 125mph. Ooohhhhh Yeahhhh. You can really hear that intake sucking. Left lane all the way. still in 4th @ 130mph. I can feel that she still has more. 135mph still in 4th half way to red line. :shock: I still can feel the excitement on monday. Oh by the way the radar detector that I use is the escort passport 8500. 8) :D with all the results. Now time for the Crawford V5 and pulley and another road test. :wink: :evilbat:

At First....

It was acting wacky. The ECU that is. It takes a few days to adjust to the easier breathing intake but after that it is all uphill in the MPG's. right away you start feeling the horsepower/torque. then later you benefit those extra MPG's. I average 80mph when I drive, which is mostly highway driving. And I also use super unleaded for that extra octane. Try not do drive to aggressively with the hard accelerations all the time. Granted You need to have fun sometimes, just be conservative. I think once I install the crawford, I should see a little more gains. :D

Initially I was in the range of 13.5-14. After the install and the 22K check up. I drove over a hundred miles on the highway hoping that it would speed up the process of the ECU adjusting. Whatever it was, it happened in my favor. I was worried @ first so I had asked Sweetfx How long will it take. I wonder how much more will I get with the crawford. Does anyone have a similar fact of this matter??? :?:

with these results, (and not even with the crawford plenum or U.R. crank pulley yet) would one even need to invest $$ in the Super Charger? MPG couldn't improve that much more vs. dollars , could they?

:? With a supercharger, your MPG will be negatively effected - Most likely by a LARGE margin because you'd be more inclined to step on it every chance you get. At cruise/hwy speeds, you'd get about the same MPG as stock because of its bypass valve.

It all boils down to what you have available under the hood when someone provokes you and you want to put them in their place.
How fast you want to pull away from them.:lol:


I agree about the MPG decrease w/ the supercharger. And for now I will wait until the gas prices drop some before making a decision on buying that. It looks like I will be waiting A LONG While. :lol: I am Avg.ing 80$ a week in gas. Oh I also noticed a little more when I disabled the VDC.

does the Stillen SC come with a fuel pressure regulator and fuel pump? The comptech SC for TL's didn't decrease the MPG by too much.

The specs. that I came up with is directly from stillen and the only thing that needs changing are the spark plugs.

This Supercharger kit requires that you replace the stock spark plugs with plugs that are 1 heat range colder (see part # NGK7654).

If I recall correctly, the Stillen SC uses the stock fuel pump and pressure. It provided the exra fuel needed via an additional injector mounted in it's manifold.
