Re: Supertech valvetrain for boost
A lot of the 900+hp guys in my state run all Supertech everything with zero issues.
The one thing I'll say though that most people don't think about, is Titanium retainers do wear. Almost all dropped valves are caused by titanium retainers (all brands) being used for too long without being replaced. Steel retainers do not wear. If the car is not driven a lot, Ti is fine. If the car IS driven a lot and you don't want to replace the retainers every year or two, stick with steel retainers to prevent damage. Some people will debate this. But the fact remains that I have never seen a single valve drop when steel retainers were used, not even with over 100k+ miles. And I've torn down a LOT of engines over the years, steel retainers never had wear, Ti retainers ALWAYS had wear
