From filterbox to throttlebody
I am new to cars and only recently acquired a firebird. It came with the L98 350 engine in mine (5.7L) and i am looking to improve performance without breaking the bank or extensive breakdowns of my engine.
Seeing as i just began my adventure into the world of engines, and do not possess any tools other than a 180 piece ratchet set i bought at Lowes, I was thinking the best mod for my engine in my capabilities would start with the intake and throttle-body.
Throttle Body Help:
I've read about monoblade throttle-bodies to open up the stock restrictive and i am looking for recommendations. This car needs to stay street legal and I am not looking for an airdam or getting a new hood, stock look as much as possible.
:edit: searching the forums has yielded that "porting my plenum", which i doubt i could achieve myself easily, would be better than a new throttle-body. I understand the concept of porting the intake manifold on my car, but lack of experience and no way of telling if im doing it right/ inability to fix any mistakes means NO thanks.
Attached are some pics of my engine bay.
Replacement Intake Pipes + Filterbox:
The area in the picture is the passenger side of my engine bay where the intake filter box and what i believe to be the AIR system is for my engine.
You can see from the pictures there is actually a mounting bracket that bolts to the frame and then the airbox and AIR system bolt to that.
What i would do is take the mounting platform out completely and bolt the AIR system directly to the body of the car underneath, then cut a hole through the frame large enough to fit a 4" diameter pipe through and mount a new cone filter under the car frame so its always getting fresh outside air. Obviously i would build a splashguard around the filter.
After that, i was thinking of dissembling the MAF and bolting just the sensor inside a larger diameter pipe, which would free me to custom run the intake system anywhere I need, instead of following the twists and turns of the stock piece of crap.
What i need to know is what you guys think about my idea so far (i think its pretty good for someone with no auto background) AND what temperatures are the intake pipes subjected to, so that i can choose a proper but mold-able/bendable material solution. Something with some insulation to keep the hot engine bay from warping the air as it passes through the tube.
