WHAT ARE THE NUMBERS !!!!!!!!!!!
Its Killin me dont make me call you this late at night

Miata cams yes.Josh wrote:what plugs are you running?
Thats what Bugs's problem was. was putting down 148 WHP, changed the plugs to a colder plug off of a MX6, and BAM next pull was 212 WHP.
just a thought.
hey did they actually cut you new cams or did they put the Miata cams in. i rember them calling me about the Miata cam swap for your car. just wondering if they actually went through with it.
but would this cause the hp to just flatline?BuGS wrote:oh ya your IC piping is like 2". You might need to go 2.5 or even 3"... But I don't know for sure...
yes it sure can. if your piping is too small you can only force so much air threw it at once. i am running 2 1/4",cjthor wrote:but would this cause the hp to just flatline?BuGS wrote:oh ya your IC piping is like 2". You might need to go 2.5 or even 3"... But I don't know for sure...
pretty sure i am running 2-1/4 on the pipe. Jason seems to think I have valve overlap. He is going to run a compression check and a visual check of the valves on Monday. Is all of your IC piping the same diameter? I seem to recall derrick saying that the piping before the IC should be smaller than the piping on the other side?Josh wrote:yes it sure can. if your piping is too small you can only force so much air threw it at once. i am running 2 1/4",cjthor wrote:but would this cause the hp to just flatline?BuGS wrote:oh ya your IC piping is like 2".

you should try stepping up the piping for sure. 3" might be a bit on large side. your not running a T4, but 2 1/4" or 2.5" would proabably do the trick.
thats exactly whats wrong with my car rite now. i forgot to set the exhaust retarded a bit. with as big of cams that i have i need to.JWMotorsports wrote: Cam timing is crutial in forced induction and to much over lap allows for cyl. pressure drop. Forced induction engines like mild cam durations with monster valve lifts. Since your running stage 2 miata cams you may need to use adjustable cam gears to decrease the valve overlap. I believe your supposed to retard the exhaust cam timing. This should also help with the turbo spooling making it spool faster. If you left the exhaust valves close for a few degrees on the exhaust stroke the cyl pressure would start to rise again but then as the exhaust valves open it would create a higher velocity exhaust pulse. Kind of like increasing fuel pressure to get a fuel injector to flow more. In this case you cyl pressure is your fuel pressure and the exhaust valve ports are your fuel injectors.
