What does happen?

I just swapped out my stock 3/8 hose for a 5/8 hose and clamped it down nice n tight to keep it from leaking. I took it our for a test drive and only made 25 psi.

My boost gauge tap is on the waste gate hose and with the 3/8 stock hose and T-Fitting i made with brass pieces. The T-Fitting had 3/8 fittings on it so the stock hose has to be greased and forced onto the hose. And i can make my boost creep up to 32 psi rarely, but it can easy hit 27 psi.


Im going to drive out to Dallas in a few minutes(257 miles) with the 5/8 hose on. and record my MPG with my new hose and what kind of boost numbers im reading.

What will happen....

well made it to dallas, going to fill er up tomo soon and find out my mpg with this. I hit 28psi on the highway, but i think it can do better with the stock hose on there.

Well time to pinch my hose now

 

i got 14.5 mpg with the 5/8 hose cruising at 68mph (2k rpms)???

257 miles highway and 20 miles city driving.

 

what kind of milage where you getting before?

 

i would get around 15.6 with my lead foot around town. MY quad is also set on 215HP


I drove back from Dallas this morning going 75 all the way.

 

So this reduced your mileage essentially.......good to know
