RobertISaar Posted February 28, 2009 Report Share Posted February 28, 2009 1. lower resistance plug wires deliver less spark? heard this from someone but not sure where... had something to do with the secondary ignition being "bass ackwards" in their words. makes no sense to me, can someone explain please. 2. front valance is necessary or else the tranny will die? what all vehicles does it effect and why? 3. no exhaust backpressure will burn exhaust valves? my dad told me this one a long time ago and i really can't figure out why it makes sense if its true. seems like less/no backpressure would allow exhaust to move quicker, transfering less heat to the valve/head/seat. i'm sure i'll have more as time goes on, but these three stuck out the most Quote Link to comment Share on other sites More sharing options...

A valance not there will not cause your trans to grenade. 3) Not sure, but I've heard less back pressure = more HP but less TQ Quote Link to comment Share on other sites More sharing options...

slick Posted February 28, 2009 Report Share Posted February 28, 2009 The warmer your engine, the more efficient the combustion cycle is. Hence the reason for WAI's on "hyper-miler" vehicle's. They even run warmer thermostats as well. 3psi, I'd like to see proof of that, with a proper vacuum/boost guage. Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted February 28, 2009 Author Report Share Posted February 28, 2009 that may be why i saw 3psi... i don't know what exactly other people do with their cars but i did find it odd, to say the least, that there was positive pressure. i assume you might be able to squeeze a few kPA in, especially with a forward facing TB. something else: how can about every company on the market claim that CAI save gas? do people actually research these things or does everybody just listen to the manufacturer Quote Link to comment Share on other sites More sharing options...
jerry455 Posted February 28, 2009 Report Share Posted February 28, 2009 in the 80's the trans-am lower valance was required for proper airflow for the cooling of the radiator. there was a TSB about it, when the cars arrived from the plant the air dams were to low to be hauled on the truck so the dealer had to install them at delivery. some didn't and caused strange overheating problems.

RobertISaar Posted March 1, 2009 Author Report Share Posted March 1, 2009 going back to the secondary ignition thing: i've seen ?accel? DIS coilpacks in jegs/summit/etc. would a 3100 recieve any benefit from them? was spark a weaker aspect of the l82 or would there ever be a difference between OEM and aftermarket?

Andrew Posted March 1, 2009 Report Share Posted March 1, 2009 going back to the secondary ignition thing: i've seen ?accel? DIS coilpacks in jegs/summit/etc. would a 3100 recieve any benefit from them? was spark a weaker aspect of the l82 or would there ever be a difference between OEM and aftermarket? the OEM ignition components are more than adequate. and yes, the above is a WAI.

RobertISaar Posted March 1, 2009 Author Report Share Posted March 1, 2009 thought of something else while i was sleeping: aluminum vs iron heads: all factors being the same: flow/chamber size/design/etc. does running the same timing on both create equal power and does aluminum allow more advance for the same fuel?

RobertISaar Posted March 1, 2009 Author Report Share Posted March 1, 2009 another: tuning: wideband only or EGT as well? i think i read that a stoich mixture burns cooler? i have also been told that a wideband can get thrown off due to backpressure. and that spark timing will effect the completeness of combustion Quote Link to comment Share on other sites More sharing options...
