It's not yet a firm decision to get away from the SR. If I get into a build, it's not gonna be a superbad setup. That's why I'm gonna port my 113's instead of getting new heads. That's also another reason I don't wanna get into a bunch of tuning issues. I can't say it's for sure, but I think my SR's big ol' plenum may be why I'm having stall out problems when I let off the gas. The way I look at it is this; when I let off the pedal, the TB closes, but I've still got that big plenum full of air to run thru the engine, but since the throttle blades are shut, it's not gonna send near enough gas to compensate for all the air in the plenum. The engine is much more able to create a vacuum in stock sized plenums, or those closer to stock, than those that are the size of my SR. Believe me, you don't know exitement like suddenly finding yourself on an exit ramp and the power brakes don't work because your engine stalled when you let off the gas. |
