I know that everyone is anxious and curious about the dyno testing of the Tomahawk intake from Pacific Performance Racing. Believe me when I say this, “Nobody is more anxious about this testing than Ken and I.” Our patience is being strained was well.

Many of you have voiced antagonism because it has taken so long...not just the testing but bringing this intake to market. Product development is a long time coming. Yes, we hung it out, looking for interest. If there were no hype, there would be no product. At least we have a product in our hands that we can touch and test. How many products have never made it that far? We thank all of you for your encouraging comments and interest.

Well, off my soap box...
Testing is now complete (3/24/05). We have tested (on the PPR street/strip mule) the Weiand, Performer, Torker II, HSD, and Performer RPM but not the Tomahawk. The dyno’s computer “crashed and burned” just prior to our first pull on the Tomahawk. A new computer has been installed and we were able to complete our testing.

The result of our completed testing is listed in the attached graphic.

With the exception of the HSD (that had 8 hrs of port work), these intakes are straight out of the box. They all lined up with the ports on the heads with no shrouding or interference. The graphic also lists the engines specs.

To a certain extent, the engine specs are irrelevant. What is relevant is the variance between tested manifolds. Our initial settings, of total timing (30 degrees) and jetting (76/80) where optimized settings on an earlier test utilizing a Performer RPM. The Tomahawk liked a little more timing (32 degrees) and so we also tested the RPM at that level. Peak Hp and Tq were not as good with this timing change on the RPM.

This engine was built for use in Ken’s boy racer ’69 Firebird streetcar and will be installed (with a Tomahawk) after all testing is complete.

We have confirmation from the factory that the first intakes should reach the port of entry (San Pedro) by the end of April. You can order yours now at www.pacificperformanceracing.com
