On the tight side or loose side with FI? Does it really even matter? Please share your thoughts.

 

i am thinking the same thing. which one is better for FI.

 

Too tight burns valve seats. Too loose lowers valve lift, makes additional noise and causes additional wear.

Go with the the stock specs.

 

I am at stock Spec,but stock says 0.25-0.29 ex i think and 0.20-0.25 in.. so which one..looser one or tighter one?
but definetly at stock.

 

^That is what I meant. Stock specs allow for slop, so I wanted to know if there were any benefits by running the looser or tighter side.

 

I have an modified head and F/I setup like John_Z as do many others I'm curious too.

 

i have to say that the Valve clearance isn't an exact science but when you check for valve clearance do you leave them looser or tighter when you check them,i personally leave them looser if i can,not on the tight side.

 

I ALWAYS have went to the tight side of the stock specs. It will give you the best lift while still being "safe".

 

I always go with the tightest stock specs.
