Unsealed - Life Beyond the Bolts July 25th, 2021 (Video)

Welcome to our show Unsealed: Life Beyond the Bolts! 

Each week, Kate Dillon from Crate Insider and Steve Hendren from Hendren Racing Engines go live on the Crate Insider Facebook page to chat about world events, random things, and to answer tech questions.


Kate and Steve have had a great week of getting stuff done. Kate has been furthering the process of her new warehouse, as well as catching time to get into nature on her kayak. Steve has had a busy week dialing in the numbers on his sons race car with dyno time, and catching up with good friends over some drinks.


We’ve developed a stumble in the corner since installing the flat air filter base on our 602…is this a coincidence?
Brisk spark plugs ….. might ya know anything about them? Good in your 604s?
I have a dirt works dw8 running a crate but open motor headers. How much power am I losing?
Can you tell us the proper way to do a leak down?
Do you suggest a 604 header be 1-5/8″ primary to 1.75 to 3″ collector for tracks to 3/8-mile ….. or ?
How many nights are NGK’s good for 602 sport mod. 100 octane Sunoco?
On the talk of fans. 2 blade 3 blade or 4 blade fan on a 602 crate. I have a 3 Blade 18”?
Is 20/50 oil to much for 604?
