hey guys, in a high compression (12.5:1) N/A motor should i use a titanium retainer? ive heard that they tend to wear quicker. are itr retainers just as good? let me know what you guys think. thanks

 

OEM is fine.

 

wassup len? happy b-day. can i rev those retainers fairly high, say 9200+ rpm's. not that i will be doing that everyday, but once and a while

 

i wouldnt rev 9200+ on stock ret, but then it matters on what cams you will be running?

If you are going to run stock cams no reason to go up to 9200, but looking at the compression i dont think you're running stock cams.

There is a special coating you can get on the ti. ret that basically eliminates all wear, i know JUN has a new type 2 ret that is already nitrite coated. Ive been using the JUN type 2 ret for about a year now, and just pulled the valve cover for a valve adjustment and still no wear, compared to a friends reg type 1 jun ret which are already starting to show some wear.

 

running skunk2 stg2 cams. im not saying that i will rev that high, im just now sure where my peak power will be after the car is dynoed.

 

hey len, did you use stock retainers on you killer setup??? how high did you rev that thing?

 

I bounce off 11,000rpms occasionally and 10,000 daily with stock retainers. No problem.

 

and that was recommended by toda and yack, correct??

 

ti retainers are more for weight savings than for strength increase.
If you have enough valvespring then stock retainers are fine.

 

what about the rev limit on retainers, or is that more a question of the springs?

 

stock > TI

 

Jack, What retainer is that?

 

thanks jack!!!

 

any brand will do this

these were portflow

my "spoon" ti's did the same thing also

have you inspected for cracks yet or you're waiting for them to break on you ? very dangerous.

stock steel retainers will crack over time and high rpm rev limiter bounces, the stem starts to sink as well.

Do the same rev limit bounce with uncoated Ti retainers and they wear inside and become flatter and flatter, they just won't crack and break like the steel.

I have seen this on a couple different ocassions. Very scary. I check mine regularly.

 

What about the Ti material Crower uses to make there retainers TI-17? supposedly stronger?

Hey Greg,

I use to not have a fun limiter when I had hondata. Then some asshat put it at 9,100RPMs when I got the EMS.

So those runs weren't really bouncing off the rev limiter, more of just running up there and shifting. I was literally trying to blow the damn thing up just to see. But like Murphy's law if you want something to happen it won't.
