a turbo is the best way to go. My GN get's 23mpg's and run's in the elevens. who ever said a turbo drags down the motor is confused. A turbo is free power. Make sure you have a free flowing exhaust and a good fuel delivery system.

this is one of my favorite vids. it's a long video but worth watching. Remeber, you are watching a car with a V-6 in it and the drive to the track is about 45 minutes.

Look at the power they are getting out of WRX's and EVO's. The GN's are a 24 year old car now and still getting respect from the V-8 world.

Thanks guys!

302 parts make 302 horsepower no matter what the cubic inch is. If you put parts on a 347 that are barely adequate on a 302, you are going to be highly disappointed. An e-cam is a horrible choice for a 302 and its an even worse choice for a 347. Likewise for Performer heads. A 347 will need at minimum a good 185cc head, a shorter runner intake and a cam to match....or it will perform like a 302.

Nobody said a turbo drags down an engine. He said a supercharger drags down an engine. And that's a 3.8 V6. I would hope it gets 23 MPG

That's pretty much where I was going with my question. If he just used his 302 combo,and added the cubes, he didn't help it out much.

I can totally see my basic ass 347 cracking a 10 when I cam it. Just takes decently planned parts. But I'm a cheap bitch and don't wana buy a cam/exhaust/cage

[69fastback]

I hope my 408 does.

[93hatch]

Lmao there's a lot of 11 second 408s dude. People like spending money to go slow

look at post #7.

yeah, it's a V-6 in a 3400lb car with the aerodynamics of a brick. if it was na it would get terrible mpg's from trying to move that mass down the road.

[69fastback]

Lol.....if it won't go 11s, I'll burn that bitch to the ground.

It should go 10s in my car. It would go 10s in your car with ease. I have to overcome weight, leaf springs, and overall poor suspension geometry.

Yep, guess I missed that part of the post.


I don't agree with N/A comment and it getting worse mileage. By that theory, you're in boost to get it down the road, and that would give you worse mileage. My GN ran low 11s, and got 15 on a good day.

[1FAST6]

we could argue this stuff all day. There are too many factors to answer the op's question. Look at the 2010 Z06. 505hp and fuel economy in the 2x's no turbo.

Now look at the evo. big ass turbo hauls ass as well and great mpg's.

what I am saying about the turbo vs na in a regal is that a turbo is making efficiant power at part throttle with little boost and fuel. with a na motor you would have to get on the skinnie pedal a little harder to get the mass rolling. maybe i'm reading to much into it but i think a turbo car is more effeciant than a na car.

[69fastback]

Yeah that's why i stick with my original post

[93hatch]

Who the fuck builds these cars to keep their foot out of them? If you saw how hard I drive my car you'd cry for my motor. Kinda hope it dies so I can build it again more compression and more cam lolzy

I agree. I beat the crap out of mine, and personally don't care what kind of mileage it gets. I have other vehicles for that. I will probably be a little more careful with this one, because i spent some change on it, and it has the potential of tearing a lot of stuff up if I drive it as hard as i did. I cant afford to just tear this one up for now. If i get a chance, I'll post pictures of the the bearings out of my 351. Im lucky that thing didn't blow up. The bearing show just a little copper ....lol

You are reading too much into it. Takes the same amount of air and fuel to make said horsepower and torque to cruise down the road at the same a/f ratio. But the two motors should be built/cammed differently, so the two are not comparable at all.

You're confused. A turbo is a restriction. Restriction in this case = drag. A turbo is less drag than a belt driven supercharger. It is not free.

Congrats on having a turbo Buick - they are sweet!

You are exactly correct. A turbo does create drag but the benefits obviously out weigh that. Nitrous oxide is the most efficient power adder and the only one that creates no drag.

Hence the reason ALMOST every drag racer on my local site sprays and doesn't choose a F.I route. And, you can be precise with the amount you want to shoot.
