Holy moly i get like 25mpg average after putting in the ssv. I thought i just had a good shot of gas at first but the 2nd tank got me 410 miles on about 14 gallons. Do the math for me!

 

Is it possible that the Z is running lean? Once the ECU “learns” your new mod, it will signal the injectors to add more fuel. Then fuel mileage will decrease. Maybe?

 

I hope not, i'm liking the extra power and the added fuel efficiency -.-.. and the sound. I want to hear a crawford or plenum spacer to know what it sounds like.

 

hummm...you're the first to report this milage thing.

 

Not alot of people have this manifold, i only know of 10-15 on all 3 forums i visit.

 

Hey me too I just put the SSV on last week and I have notice the power gains and the fuel milage went up too.

 

Cool! Btw, did u have problems getting the intake tube to fit under the strutbar after putting it in, especially on the TB side

 

How many miles did you drive since the SSV install ? Is it still "economic" after a thousand miles ? What other breathing mods do you have ? Thank you for the information.

 

do you have turbo with your ssv, my mileage is crap

 

The install was not hard at all. Well except the 3 screws on the one side of the SSV they were time consumming, but the tube was not even a problem.

 

I have had it on for about 900 miles and so far im at a steady 24.3 mpg w/ highway and city, and i drive it like a michael shoomocker (sp?lol). It used to be 18.2.

The key to gtting the bolts in is it put the bolts into the SSV before u put it on the block, and tighten them just a little bit after

 

Are you NA? Did you dyno it yet? Any tuning requierd? How much hp did it add?

 

NA.. didnt tune.
