The folks at Crate Innovations have been working to better their own product!

Several years ago, Crate Innovations developed a one-of-a-kind angled carburetor spacer for the GM crate engine.

The original ‘Accelerator-1’ is now being replaced with a new and updated design. After extensive examination, careful study and testing, our team of innovators discovered what works best with the original design and made modifications to those areas where the original product was lacking.

The DYNO numbers were pleasing from the first cut of the spacer, but we know that DYNO results are not always the best test for this type of product; so, we took the product to the track. We used several different test sessions, multiple drivers on various tracks across the United States. Favorable track testing aligned with our DYNO results!

Therefore, we are proud to announce our new and updated version—the Accelerator-1 PLUS!

And get this! Owners of the original Accelerator-1 spacer will receive a 30% discount with the trade-in of the old part and a receipt from the original purchase. (If original receipt is not included with the old part the discount will be 20%.)
