seems like about like the twister thing that napa sells for 50.00...just a note when you added a spacer to make the intake taller you lose lower end and add about 100 rpm on the top for every inch. I would rather use 100 bucks for a bigger maf just my 2 cents

 

Never seen the Napa piece...interesting. Gotta' check their stuff out more.</P>


Yeah, I had it totally backwards on the intake height/torque ratio. My mistake for the day, I guess. More height equals more hp, less height equals more torque, everything else being equal.</P>


I agree with VFAST about where to spend the $100...I'm still a recovering carburetor user of many years, so a lot of times I don't even think of the FI pieces you can bump up. VFAST, your .02¢ was really worth .25¢...good idea.</P>

 

Hawks, go to www.3.8mustang.com, register, and ask in one of the technical forum about Flex's spacers. Flex is a member of the site, and makes throttle body spacers. Many people on the site swear by them. Good luck<IMG src=smileys/smiley2.gif border="0">
