Its an OEM turbo so the headers are I think are equal length. Which I know gives a higher pitch than the unequal length ones do. I guess a better way to say this might be, I am looking for a Refined sound. Not a fart box muffler sound. The bypass system is an idea, to give it a touch of raw...

Hello, I am working on a custom car project, and will be using a Subaru WRX 2.0 liter turbo charged engine. I did a search under the question I am looking for an answer to, but only found one thread that was closed. I hope you all might be able to educate me, on what my possible options are. I...

thanks for your replies. but after a recent thread, I'll stop asking questions here

Jut seems an enormous waste to have so much kinetic energy in a wheel and not exploit it in some way. For instance, in most ICE the exhaust flow is wasted as heat and flow. It is never tapped for energy unless it is used to compress incoming air into the intake. Why not attach a generator to...

kawasaki voyager. Its a work in process, not complete yet.

Heh, Yeah I know. The wheel will not be moving any parts. Its overall weight increase would be in grams. The magnetic drag would be the only potential drag losses.

yes it is 12 volt typically. But could be a lithium-ion pack as well. i was playing with using motorcycle engine magnetos, and turning the wheel hub into a Rotor. with the stator being mounted in the non-moving portion of the hub assy. Its pretty straight forward really. Given that the...

Ok good now think of the AC clutch disengaged like you mentioned. Its still spinning that shaft. Is that noticed? No. When the clutch is driving the compressor, yes it is. This design will be little if any drag on the wheel hubs. Like the freewheeling shaft

true I understand that. But when this is attached to a 400 to 4000 lbs vehicle. The losses will be minimal. Remember its being setup to have a very small impact and offer a trickle charging effect. This is not meant to sustain the vehicle. The drain at the wheel hubs will be negligible to...

Then how do you explain two volts generated by attaching a drive cpu fan to a second cpu fan via a common drive shaft on the rotor? Just did the test. This is not an equaling effect. only a scavenging effect. If attached to a circuit capable of storing up and discharging it to the battery it...

Hello, I am working on a regenerative wheel hub design for an EV. This is not a regenerative braking system, nor is it a violation of the conservation of energy idea. The idea encompasses using the rotating mass of a wheel to provide a trickle return charge to the battery pack as a wheel is...

Thanks! Ill look into them. Im trying to iron out some details on the engine component alignments. There's always something to have to wriggle into place. A V12 has very little room to work with ironically.

I am redesigning a crankshaft to support two connecting rods per journal from it's stock one per journal. I will be machining a new crankshaft out of 4340 billet. This design will reduce the counterweights to 9mm in thickness. This engine is a 9k redline design so I need to get this right. Can...

Hello all. I am now enrolled at VRI at WWU! I am working on a sort of independent study project. I am making a V12 out of a pair of motorcycle engines to go into a VW based kit car. I have run the IHP formula and come out with 250hp, and 220 lb/ft of torque. The car weighs 1800 pounds...

Too true. There is a huge difference between using equal length headers, and unequal length headers. Additional tweaks can be had by omitting the resonator. However, I am putting this in a car that looks like a cross between a Lamborghini miura and a Ford GT. So getting the exhaust note both...
