Extreme Velocity Hat
Are they worth the expense vs performance gained over what is typically supplied with Procharger, Vortech, Wynjammer, etc?
I recently installed a Wynjammer on my stock 92 454SS and it knocked a second off of my ET.
Looks like you guys could easily adapt this to 3rd gens.

Re: Extreme Velocity Hat
most likely for the power levels you'll be looking at, the $69.99 spectre one from pep boys will work just fine, couple guys on theturboforums.com swear by them and they also tested a/f ratios and they were unchanged between the two. save yourself the money.

Re: Extreme Velocity Hat
I have a YS trim that I will eventually be installing on my other truck. I may get the Extreme Velocity hat for that.
What's the best method of sealing the hat to the TB?
Thanks

Re: Extreme Velocity Hat
I use it with the 1" spacer. From my expierence, much better than stock ATI set up. The stock one only seemed good to about 6 psi. ATI does offer there " tall boy" which is better than the base one. Plus, the EV hat has an o-ring to help seal.

Re: Extreme Velocity Hat
yeah, most run the 1" spacer, even with the EV or EV PRO hats.
