Hi Everyone,

I'll chime in and add my 2¢.

If you're building a car that will see primarily street ... and operate in the 2000-3500 rpm most of it's life ... and operate above 4000, up to 7000 a couple times a year ... I'd suggest Mast or Lingenfelter. They will work great & cost you less.

If you're building or running a car that will autocross 10+ times a year ... and/or run on track days 10+ times a year, where it will see 2000-7000 rpm a lot ... a whole lot ... I'd recommend one of my engines.

My engines cost more than Mast & Lingenfelter, because we build them with better, stronger & more expensive parts throughout. We build them to handle high rpms & hard use weekend after weekend & live. If you want to read why & how our engines are built to shine in autocross & track days, read HERE.

Thanks & take care !
