Yeah a lot of good points here - the plan is to put the lower in, run tests, if we still have headroom and aren't pulling a ton of timing throw the 2.75 and see how that does. From there I can look into potential cooling options like the Interchiller as well as wait for the aFe intake to come out. Being the "first" so to speak has it's cons, still waiting for a lot of these TRX specific parts to come out.I think everyone would gain a lot of knowledge on here if they spent some time watching banks power youtube on building power on a duramax. Its a diesel but a lot of the basic things apply. I learned a lot on a sti turbo on compressing air and power. Anyone correct me if I'm wrong. I never got payed to boost cars or anything. Just another hobbyist who loves power. So my thinking on the spacers is since the blower is compressing air its generating heat its self. So the spacer plates is not going to do a hole lot as far as cooling goes. Especially when your running pulleys and running more boost. On the sti it was huge but the hot air was cooled before it went into the aluminum intake and the runners were about 20 inches long so the hot plenum had more time to transfer heat. I was thinking of getting one of those inner chiller set ups where it uses the ac to cool the blowers after cooler water circuit and in my mind all this would do is cool the air and help prevent predetonation. The power you would gain would be from timing not so much denser air as its after the blower. The more presure you create the more heat you create.
Now on to the headers. Id say it was a good idea with your mods. There doing a lot more then making noise. Your blower is a fixed displacement pump and it moves a volume of air per rotation. The pulleys are increasing the rpms and the pump is moving more air. Pressure is created by the resistance to the flow of air. The side affects of that resistance and pressure is heat. So the headers and exhaust helped reduce some of the systems resistance to flow of air. There by allowing the blower to move the same amount of air with less heat and pressure allowing more timing and or safety margin. The blower may even move a bit more air due to what ever losses there are of air slipping past the screws would be less due to the air being denser and at a lower psi. Air density is the key to power and figuring out how to get there efficiently is the key in my mind. You can crank up a blower but at some point it gets to a point of diminishing returns.
on the intake note im waiting for afe’s intake as well. I just cant see pulling 180 engine bay heat into the air intake and asking the blower to heat it up more. Most cold air intakes should be called hot air intakes. Afe has the right idea in my opnion and they told me they plan on having a dino sheet once there testing is done. I think theres a reason the other companys don't have that. If your drag racing and you keep your temps down it would help but everyday driving it get hot in there. Maybe thats why bwoody has a special harness for the intake temp. Its says in the description some comstomers are getting intake over temp and a harness fixes it? Im no pro so correct me if I'm wrong on anything.
