I searched the go fast lab and bulletproof automotive's site, and could only find toda springs with no details about them, anyone know where to get stronger retainers and springs that will withstand higher rpm's before valve float? I'm trying to get the retainers asap, all this talk of split retainers worries me

 

Some of the guys over in track may be able to get you a vendor. I believe a few of them have switch over to Ti. How about Bill's recommendation of AP2 retainers?

Bill, please let everyone know that everything is going to be alright!

 

You can find them at Laskey Racing:

any idea on what point those springs at laskey start to allow valve float? i think i read somewhere that the toda's will allow 9300 rpm, but dont quote me on that

 

Call Earl and ask him. A few people on this Forum are using them with their rev limiter set to 9200 rpm.
