How Good Are Rb26 Valve Spring Retainer

[SiR_RB]

Just noticed you mention stock everything, awesome stuff !!

When is a titanium retainer necessary? When running dual springs?

I ran my Poncams (260 @ 9.15) on stock springs without problem. Reved fine to 8k. I thought poncams were set up with ramp rates and everything so that drop in without any other changes were ok.

My new set-up has Procams with 260 @ 10.25. So I went Supertech Valve springs that come with Titanium retainers.

Based on Paul's (Piggie) experience, the extra lift and ramp rate is what caused his to flatten out and couldn't rev it out.

I decided while I'm doing cams may aswell upgrade the springs too

With those procams Eric did you get new buckets aswell?

Paul's car flattens out cause the turbos run out of flow

Naw running stock buckets. Didn't go oversized.

Brett, I was referring when if first got the head back and it hit a wall at like 5500 rpms.

Regardless, with Poncams only 9.15 lift so you'll be fine with stock springs and retainers.
