Thinking about trying a TR220 cam. How many miles do you have on yours? Which valve springs are you using and how many times have you changed them.

Thanks.

I ran my TR220 for about 8,000 miles and used 918's the entire time. When I pulled the heads/cam for an upgrade, I had the 918's tested and they still looked good. That cam and 918's will live together happily for a long time.

I've had a TR220/114 in my car for over 20K miles. And many of those miles have been on a road course.

I had 918s on it for about 1/2 those miles, found some ported heads that already had springs/retainers so I sold them.

This is a great camshaft for a daily driver.

With just cam and headers, I increased 40rwhp. Heads and intakle gave me another 30. I'm curretnly at 380/380 at twheels, through a full Borla
