What do the green numbers represent in this map, I thought it was rpm. But it doesnt seen to correspond to this map.
Idk I went to a Cobalt forum where obviously they will know more about the charger than us, and the 14,000 rpm s/c redline is what they say is max for the stock pulley. Without the circumferance of the crank I cant realisticaly come up with a suggested s/c pulley size.
Is the stock s/c pulley 4 inches?
Ill get out the calipers later tonight and see if I can get some dims of the pulleys. I also asked ECS what there lightweight pulley diameter was (the standard, not the underdrive). Maybe ill get an answer there.
ECSDumb, that didnt help.Diameter of the stock and the lightweight pulley are the same. Our ECS lightweight crank pulley is 70% lighter than stock, that is where the extra throttle response and horsepower is made!
I just measured but I only have 6 inch calipers. but I measured to the from outside of the belt to the inside of that metal ring on the outside. and then the width of that outside ring, if that makes sense. So from outside to outside with the belt is around 6.6 in. And the ac comp. is 5.195in including the belt.
Can someone with this manifold please give these measurements, I just want to know how wide the plenum is and the distance between the plenum and flange
I'll get those for you tomorrow. I don't have any way to measure it at my apartment right now but will when I'm at the garage tomorrow. If I see my neighbor tonight I'll borrow his tools, but otherwise I'll just get em later.
You do realize this intake tapers down though. I don't really want to supply that radius or dimensions to that degree. Don't want to tick anyone off. I don't see any harm in giving you the max depth of those two dimensions though. Did you also need that third dimension you marked on the TB side or is that just a mistake in the drawing? Not really sure how to reference that dimension on the TB side you marked actually. If you want to clarify that would be great.
Why don't you guys pay someone to draft something up for you in inventor or pro e? Does anyone have a template available for the 2.5 MKV bay, intake side to radiator support? Watermark it and send it to firstname.lastname@example.org, promise not to give to anyone else.

No its not a mistake. I know it tapers so thats why I included the throttle body side as a measurement. Its the widest part. Also just a rough measurement from the plenum to the flange. I think Im going to need shorter runners
I vote ultra budget build, cut the stock intake, bond silicone couplers to the runners, build slip on runners w/clamps, screw the IC, see if you can crack the nylon runners/flange.
SUPER GHETTO but it would work until the intake runners melted.

Meh sure it would. You have a support bracket to use unless you remove it beneath the intake manifold. Oddly enough I can't remember how it is configured but I do remember it was there!
A nylon flange w/silicone couplers that has runners slip on over it would be pretty solid I think. It also has the thermal advantages over metal to metal to metal to metal.... to metal... hehe I really don't like super chargers for how much heat they produce though so no idea if this would work. It would be cool having a modular design too, w/dif runner lengths which you could incorporate.
Welding is easier though and that $300 ain't a bad price at all. The oval runners going to be a pita though.

However all that being said, the base Hyundai Genesis 2.0T R-spec is the better tuner car rather than the V6. The base which is now called the R-spec is lighter and stripped out which is what you want because honestly who gives a frack how many speakers your car has, or if the seats are heated, or if they are leather? None of that has anything to do with performance. And the 2.0T is not the crummy turbo from the Sonata Turbo/Kia Optima Turbo. It's the 2.0T MiVEC engine from the Mitsubishi Lancer Ralliart which is internally the same as the Lancer Evo's. So right out of the box you already have a HUGE tuning potential. But it's a coupe so it's sexier than the Evo. And it's RWD not 4WD which is what you really want. Go for it man. I can't join you because I've modified my Rabbit beyond the point of no return. I couldnt sell it even if I wanted to.
My choice if my situation were different; I had no car and had to buy one? Get a used 2010 Nissan 370Z with sport package for around 27grand
Honestly, for the oval runners. I wouldn't be satisfied unless I modeled and benched a ton of different collectors/stack designs. The cylinder head has some funky stuff going on too. Either way its going to stuff air in the cylinders but you could easily gain or lose a good 40 horsepower because of these stupid ovals. They're a really superior design but a pita to work around unless you want to pay a machine shop like $2,000.
The other SRI's have cut corners in this respect though so I don't see any reason yours has to be over engineered either.
