Pete Nichols Circle D Specialties theeeeee baddest guys in the converter game hands down!!! Easiest people to work with and their results speak for themselves. Hit us up if you have any questions or just call them direct!!

Today's features Nick McGrath of Straightline Performance in his Mustang that he campaigns in Ultra Street! 💪

Nick found himself stuck in the 4.5X range last season so late in the year he decided to install one of our Pro Series 264mm billet bolt-together spragless torque converters. The car immediately dropped into the .40's along with running multiple PB's with each successive test pass. 😎

As with all of our Pro Series 264mm torque converters, we have Nick's set up with one of our premium CFD-modeled 5-axis CNC-machined billet steel airfoil stators. Nick's converter also incorporates our billet aluminum front cover.

Under the hood is a trick LS mill wearing a set of CIDHeads - Competition Induction Designs cylinder heads & matching intake manifold. A custom camshaft by Nick Evdos at Brian Tooley Racing provides valve motion. Nick runs a class legal 76mm turbo from Harts Turbo. A custom TH400 built by RPM Transmissions provides gear changes.
