I never touched any material around where the plate rests at idle. Didnt remove or even polish the area. So that isnt the issue. I just think the fueling map is set up for, and around, the ramps designed into the throttle bore. My idle on a stock throttle is about 850rpms (give or take due to...

Thanks for the info guys. The poorish idle situation is definitely a product of taking all the material away from the immediate area surrounding the throttle plate. Im guessing bigpaul hit the nail on the head as to why its so irratic now. With the idea I have, the secondary throttle isnt...

Idle is operated by a TPS sensor built into the OBDII throttle (which my car uses) The secondary throttle would use an OBDI throttle which, in normal circumstances, is controlled by an ISV (idle stabilization valve. Both throttles are DBC. The whole reason for two MAFs is to have two throttles...

For manifold design, I was considering two ram pipes with throttle body flanges on either side of the plenum ends. Run them to either side of the bay into their own MAFs/filter housings. I was considering the 2 throttles into 1 MAF idea, but it's already been done and I wanted to try something...

Say I wanted to design/fab a custom intake manifold that utilizes two throttle bodies. I'm just curious on how you would be able to wire two MAFs together to read the load. What I was thinking is having two throttle bodies. The first throttle, which would be an OBDII (with the integrated TPS)...

Im usually a lurker, but i wanted put my 2 cents in... 292* 38/74 - 74/38 106* LSA 108* IN CL 104* EX CL 252* 21/51 - 53/19 106* LSA 105* IN CL 104* EX CL These two cam profiles are worlds apart. The new 252* profile (not 274*) will produce massive low end and give you no reason to rev past...

So....if this is a four stroke: suck squish bang blow What makes it a six stroke? foreplay suck squish bang blow cuddle ???

Was curious fo the effects of ride height on an auto in relation to fuel consumption. I am trying to resolve an argument and would like some solid info to back it up. I am thinking that, on an average car, a lower ride height would result in a better mpg rating. Resoning: more air going over the...
