Sounds good!



I still have yet to remove mine (with the pineapple inserts) to check for damage. I used red loctite.

i believe what was causing the engine damage was it hitting that lil bar thing and knocking it loose and hurting the engine, not the sleeve itself. but i could be wrong. so regardless of material, it could still cause damage.

Re-read my above post on my reasons for using nylon. Its soft enough that if it were to come loose, its unlikely to do any damage.



I had 2 sets similar to this in my car for over a year each with no problems. First set didnt use the sleeves, it was just pressed into the runner. Second set was in a sleeve, but it was with my bridgeported 6 port, which had the sleeves cut down so they wouldnt limit flow. I pinned this set into the sleeves because if the modified sleeve. With a stock sleeve, there should be no issue with the insert comign loose and entering the engine.



For the people I was sending a set to for testing, Im sorry I havent got them out yet. Ive been out of town on business and havent had a chance to ship them yet. They will be shipped this week though.



For everyone else, Ill have these up on my site available for order this weekend of next week.

I think your best bet would be to buy somebody before and after dyno time. That way, you'll have some numbers, as well as peoples' testamonials.

+1 on dyno numbers. that would sell me on a set for sure if it actually showed an increase on the non butt dyno
