I was just wondering what some of the main advantages of all motor are over a turbo or supercharger set-up. I am not trying to start a heated debate, but I am trying to understand some of the benefits of going all motor over forced induction especially with build cost vs power... forced induction has a much better bang for your buck. Obviously when built right both set-ups can be very fun and very fast.
Why is all motor so good..I don't fully understand why?

Thanks to any answers or opinions.

 

to me its just a matter of opinion.. i like having an allmotor car.. if u have an all motor car and go walking on some mustangs and bowties there like what u sprayin or turboed or somethen..and ur like na man all motor 1.8 or 2.0 or w/e...

 

not ever having to worry about blowing it up cause i am flooring it in 5th

 

Pure atmospheric power.

It doesnt get much better.

haha yes but no, if u think about it an all motor car is always under load, and a boosted car u can just turn your boost down to wastegate and u can actually stay out off boost. but hell with turbos all motor for life

 

There's something more noble about it. It's actually quite...beautiful as gay as that sounds. That's the way I feel about it. It's like raw art in motion. Whereas turbo is like photoshop. I probably make no sense. LOL!

Respect...showing up at a track and running an 11.8 NA is a lot more impressive and respectable than an 11.8 boosting 18psi.

 

Coming from a turbo guy: i didn't know it was a point to try to make power the hardest most expensive way possible. Essentially what all motor small displacement engines do.

But you know what, I love them. They feel great when tuning them, especially with a nice set of cams. They suprise me sometimes... But a turbo still does it best for me.

 

When I thumb through magazines--weather they are import or domestic Mustang--the well built NA cars (and I don't mean stock cars without some sort of forced induction) are really what grabs me--even against a well built turbo car. Like said earlier---there is a purity to it and to an engine builder or someone fascinated by engines--its all about massaging power any way you can---seeing how clever you are. I am not going to say the rehashed "turbo is easy, all motor is much harder" because there is nothing easy or simple about a 900-1000 hp Honda motor--it still requires tons of work, preperation and thinking but NA is about as pure as it gets--you tinkering an engine sucking nothing but atmosphere. Add to that, while a quick turbo car is fun as hell, the immediate response and "bark" you get from a well built, quick ITBd or sidedraft carbed high compression motor is just ridiculous.

 

myself i was a boost head, but now allmotor for me. boost was just too inconsistant
boost spikes, boost creep, every time i beat the car i was like "glad it didnt blow", just felt guilty about it. all motor is more respect in my opinion, you have too do so many little things to make power

 

because i could do 11.90s on slicks on sunday, then let my mother drive it to work on monday.

a fast all motor setup is much more impressive than a boosted setup IMO

you dont need 500whp to have a fast car

almost anyone can bolt on a turbo kit and say there car is "fast" but fail to take time to understand the dynamics of the engine and which parts will work best together.

my favorite qoute about this topic is "turbos are for people who cant build motors"

The original was "aerodynamics are for people who cant build engines" and was said by the late great Enzo Ferrari.

yes!!! to actually put parts together that work all in harmony

****...glad my APR double decker GT wing is getting shipped out to me soon

 

because when you see an all motor monster you think, wow a lot of time, effort, blood, sweat and tears went into building that. while with a turbo set-up, you see it and its like big deal, so what? you slapped a turbo kit on your car and turned up the boost. Its just not very impressive in my opinion

You ain't kiddin... I had a friend with a supercharged '99 Si, and it had one of the APR 3-level wings, and that thing was stupid fast!!

 

its just personal preference. you can get a turbo car to drive like an all motor car on steriods. all motor car getting respect vs turbo car running 11's? what if the turbo car was a single non vtec stock internal running the same time as a built all motor engine? that **** will defintaly get respect.... it really depends what your goal is, how you want to get there and how much $$ you have..

 

Wow great response guys.
I am open to both forced and all motor. I just wanted to see where you guys stand. I am happy to say you guys show alot of respect for each persons preference aswell.
Thanks for all the great info...bump for any more comments.

 

you bolted on a manifold, turbo, down pipe. then ran some piping, an intercooler and installed some new injectors, then you cut a vacuum line in half, stick an adjustable valve there.

Good job now you can make as much horsepower as you want but still dont understand how your engine functions

 

Its just very interesting--trying to pull power out of thin air--but that shouldn't discredit the builders of powerful turbo combination--those setups are very well thought out too when you are trying for every last bit of power. You have to face the facts though that in a full weight street car you are going to be limited in how quick you can get in an NA combination. A stripped out race car with slicks and optimum gearing is a different story.

 

What I don't understand is everyone saying all motor takes thinking and turbos are as easy as 1-2-3 and you don't have to have a clue how a motor operates--but think of the avg. guy building a street 200 horse LS-VTEC--he is buying shelf cams that someone else already did all the thinking on duration, lift, LSA--probably sending his head for porting and valve job to a guy who is going to make magic for him--do all the thinking--buy the Hondata or use Chrome or whatever--take it to a tuner who is going to do all the hard work and tuning it for him--get an off the shelf large throttle body and one of the popular intake manifolds and then buy a header in which one of the header builder took his info and did all the thinking for him on what size primaries, secondaries, lengths--collector diameter. I am in no way discrediting the guys who do something out of the ordinary and know exactly why a certain header diameter is better or what the optimum--even custom cam grind should be--but for most of the guys who build these street motors--all the "thinking" has been done for them!! So how is this any different from a guy who throws some sort of turbo kit onto a motor he builds? Or pieces together his own kit? These fun street motor "formulas" have already been laid out and set in stone--so I don't think people should be patting themselves on the back for their "complicated and groundbreaking" avg. builds.

You love my timing-hating, noisy, 13-second all motor sled!

But seriously, I just like all motor cars. I like having instant power.

Sure, in a heavy car like my coupe, I could go ALOT faster with a turbo. But to me, it's more like a challenge.

All motor people will spend alot of money for like, 2whp.

To me, it's all about respect. In my experience, alot of automotive enthusiasts (older V8 guys, sports car 'purists') have alot of love for naturally aspirated engines.

 

just got a call from my SRT4 buddy. he says

"man im getting boost leaks, its only boosting 4psi and i just got walked on by a scion TC"


i think that pretty much should be the END ALL right there.

 

I think the engine matters. Before I say anything let me say this, I'm talking about street cars and not purpose built race cars. That said, an all motor D-Series hits its limit at about 170whp. If you want more you either have to take it off of daily status or you build the engine for FI. With a B-Series you have a lot more potential for all motor power so it'd be a better option.

If someone doesn't respect a faster car because it has forced induction, fvck 'em. It's a loser's perspective to say, "yeah, well, you only beat me because of that." You lost, deal with it and move on.
