Decided on a replacement for Go Man Go

[Demoniccat]

I would have to agree with you. 3,300 miles here, no issues. Broken in per recommended break in procedure. Almost all E85 miles. Few 93 pump gas fills with common sense right foot pressure. Unfortunately now sleeping for few months till spring arrives. While in storage it has pump gas.

As Jack mentioned, it was the blower. They've now installed a Gen 6 Whipple and a 3.0" pulley making 21psi and eclipsed 1000RWHP. Then proceeded to beat on it. I'd say these engines are just fine as long as assembled correctly.

Looks like RacerX
Got his figured out now
Wheels up just shy of 8s

Interesting...looks like there's now a full campaign on replacing the plugs in all Demon 170s. Couldn't find anything on the replacement PN on Google, maybe because it's a kit. Mine's never had a problem, but I'll get this done now that it's a thing.

Shows a shop time of 1.7 hours so all these stories about plugs being hard to change must be folk lore
