Hm all this started by me asking a simple question. Hm perhaps a fuel economy thread is in order

I dont... if i did i wouldn't have done it and spent 2 fucking years figuring out how the hell to put it into an s13... durrrrrr


but now that its all said and done it would be nice to not go through a tank in less that a week.

Got some more parts in, should get more tommorow as well. Im hoping this whole car comes together in the next few weeks as im very anxious to drive it again.


Exchanged my steel driveshaft with mazworx for an aluminum one





Got some fittings and hoses for the crank evac and powersteering cooler





Some misc brackets and pulleys from powder coating ( matte black )





Got the valve covers too, done in wrinkle black this time, red is getting played out

[chairmnofthboard]

Who did that wrinkle finish? looks great.

[SidewayZ-s14]

Jeez, you have got to be loaded with $$$$.

I'm way jealous! Keep up the good work. Everything is looking so awesome.
Can't wait to hear how it runs! :]

[Future240]

^he has vids of the first one

[JRas]

This one is even better

we want more videos this time too!

people who are intelligent? who wants a car that gets poor fuel economy specially with gas prices rising?

yeah, because all V8's get poor fuel economy LS1 gets 28MPG

try this new thing it's called thinking before you say/write all the 'cool' people are doing it.

Doesn't mean you were driving for best economy.

[champagnes13]

hey i love the wrinkle finish valve covers, i think i'm gonna bite that. srry.

the throttle response and power in your car must be amazing for drifting. vh is definately a cool motor, i like it in my q45, but hate the factory gearing (and vlsd for that matter). 60mph in first? 100 in 2nd? weak....

[PoorMans180SX]

Maybe you missed it the first time, but what final drive are you using? Seems like it would benefit from 3.69 gears.

[gsracer]

Using j30 rear gears, i think its good combo with the z32 tranny

i know. but this was driving 600 miles straight to rapid city. At a constant speed on I-90... at like 70 or so mph. maybe 75.

Aw cute. listen dipshit, last time I checked when people modified cars, MPG wasn't at the top of the list.

when my friend bought a 1966 Fury, MPG wasn't a concern.

when I bought and modded my 1972 beetle, MPG wasn't a concern.

all I'm saying is, if you want MPG, the way top get the most is to leave the fucking car alone.

i realize with gas prices, its a bit more of a factor. I just think its funny how people are worried about it but yet they still crank up the boost and throw V8s in cars.

and don't give me that condescending think before you post shit, I was mostly joking.

so in short, I was joking, go fuck yourself.

all I'm saying is fuel economy is an important factor and people shouldn't be abused because they asked the question.

/done

[Antihero983]

and all I'm saying is not to everyone.

Hey, the guy asked a question. I gave him an answer. If you don't want to answer then leave him alone.

No need to insult or belittle people if you don't like what they're doing.


I personally don't care about fuel economy either way, but he wanted info so I gave it to him. No need to be mean about it.

Fuel economy is probably not the top concern if you're swapping engine, but after response, power, reliability, sound, looks, and cost, fuel economy probably comes next. I'm just guessing.

[xplicit240]

all the bs aside. keep up the good work! im sure with all the money he has to do this work, he isnt concerned about MPG.

cant wait for this to finish!

[gsracer]

Got some more toys in today

Griffin radiator, stainless 3 inch x pipe















Got home pretty late from work so couldnt do much

[CrazyTrance]

WERD.

Looks hot bro. Keep up the good work and baller parts

[projectRDM]

Between all the bickering, moaning, and idiot fucks asking the same stupid questions that were already answered in the last build thread, you guys have ruined this new one. It's like you all just found the internet yesterday.

Quit the pissing, shut up, and appreciate the car and it's build.

[s13_gearhead]

This is big pimpin' bro. Your shit is gonna be hot. Good luck with the build!

[SicBastard]

Glad to see you're back at!
May I suggest doing the supercharger right off-the-bat this time, should help to keep you interested?

[CylonFrakker]

very nice. wonder if mazworx makes headers for th VH41 in my y-33

[chituntang]

You going to run dual exhaust?

[TheArkitekt]

badass! The sound must just be amazing for a setup like that.

[SicBastard]

Are you using the same type of hose for both the breather and ps? Will you post a link to the ps hose that you are using, it looks good and flexible.

Please be nice.



I talked to a Nissan factory technician about fuel economy. He informs me that the engine is the most efficient at torque peak, and therefore would yield the best fuel economy if cruised at torque peak RPM.

My V8 has a flat torque curve. I cruise at 1,500 RPM. Small displacement engines doesn't have enough torque to cruise at 1,500 RPM so they need a higher cruising RPM.

The problem is that V8 tends to come in heavier car. So V8 has a bad rep for getting bad fuel economy.

If you took a light car, and compare a V8 to say a KA-T, the V8 would get mid to high 20s, whereas the KA would struggle to get high 20s, and any acceleration at all would knock it back down to low 20s.

Keep in mind this is not theoretical. I compare my V8 to his KA-T. Granted I have carbs so I'm only getting low to mid 20s, but think of LS-series that get mid to high 20s on the highway. Now drop the weight by 500 lbs and I think you can break into 30s.

BSFC(brake specific fuel consumption) rarely happens around peak torque because it has a variety of factors that affect it(friction, pumping losses, manifold/port harmonics etc). It's typically at a lower RPM than peak torque on modern engines. Sometimes much much lower.
