opinions on thicker headgaskets?
i would like to hear some opinions on running (or not running) a thicker headgasket. was thinking of putting one on my B16 when i get it...

I think its lame, I would never do it, and think that a b16a turbo running stock compression is just fine, ---- a mini-me is just as high, if not higher.

due to the differences in combustion chamber shapes and sizes you can't on that formula but I am sure you can find out what to to for the engine you have somewhere out there - fortunatly someone had already done the math for me ;D one other thing is that when you use the thicker headgasket your timing is advanced - on my motor anyway - so you need to take that out with adjustable cam gears hope this helps!

Re:opinions on thicker headgaskets?
ok this is what im not getting. ok you lower your compression and give it more boost.
but isnt like 8.5 with 14psi making 200hp the same as 9.6 with 10 psi making 200hp or am i totally wrong? |
Re:opinions on thicker headgaskets?
I think u are correct...i was reading something about that on another site...that a higher compression turbo motor will always produce more power than a lower compression turbo motor...with the same amount of boost..

A 1 point Drop is not as drastic as you think. but that is not the only advantage you can use devices that advance timimg like aftermarket ecu's, chips, or whatever because there is much less heat soak - currently the Phatrides , neon a mid 8sec quarter mile, car has 15:1 compression and is running like 24lbs of boost - but they use race gas and everything internal is forged, and it is all ceramic coated. for the cost it is a great saftey net. |

thicker head gasket=less quench=less mechanical octane=less efficiency

Re:opinions on thicker headgaskets?
you guys should read Maximum Boost by corky bell. he states that the lower the compression the more Hp you get per pound of boost. 7.5:1 is ideal for an all out drag car and 8.5:1 for a street car but i've seen people have boosted engines with a compression rate of like 11:1 so either way it will work.

i run a greddy 2mm heagasket and it works well...
