i've notice people are doing this mod and their vouching for it, so i'm questioning it...

between the cylinder head and the intake manifold we have a paper insulation gasket, but because it's compressed paper it won't typically catch on fire, but i'm wondering how hot does that paper go or does it restrict a bit of heat because the intake manifold doesn't typically touch the intake manifold, although the heat generated will get absorbed by the intake manifold itself....

because I was looking at the insulator that hondata makes and it looks like a plastic polimer that was CNC's out.. now i found this plastic and machined one but wanted to test it so i put a heat gun on it and when tempetures started to climb i noticed that the white plastic turned clear and it would become "maleable - aka bendable" now .. i'm wondering if they use a special teflon plastic or it's common teflon... i'm also wondering how hot that plastic becomes upon operation or if it doesn't because the paper on still takes a chunk out of the expanding heat from the cylinder head...

I can't test mine because my motors appart.. but it's well designed..

any suggestions/comments on this...

mine is quite thick because further injector placement is actually better for N/a applications... (but we won't go there for this discussion

thanx for the help guys...

oh my motor is h22a...

 

ttt i wanna know this too

 

didnt know it was teflon at all thought it was urethane.

 

i though teflon was more rigit then urethane... ....

 

you might be right look at this http://web.umr.edu/~wlf/Synthesis/teflon.html

but the cold flow part bothers me because with cold flow there is also much easier hot flow but teflon seems to handle heat 327 degrees vs urethane i dont know. edit: urethane melts at a much lower temp so i guess it would have to be teflon. but if i were making my own i would try nylon or phenolic resin as used in carburator spacers.
