supercharged 1.6 sohc

[kego]

okay so i have seen there is some dicussion as to a supercharged 1.6 sohc. is there any definite way to make this work with out some major customizing? is it cost effective?

No

is it cost effective?

No
The cheapest/easiest way to make power from the 4-cyl has been discusses many many times. I'll let you search on that.

i have but i like superchargers

You're not going to get any significant gains of HP though. Some people have turbo'd the sohc to impressive numbers, but I've only heard of that through other members on the board.
Even the few supercharged klze's out there don't really do any better than a turbo'd ze (from what I can tell) I think the only reason people do it is for the sound the supercharger/belt make.

If you have the time/money/skills to do it, then go for it! I'd like to see it done.

how do you figure? boost is boost. it doesnt matter if its from a turbo or supercharger. whats the difference between 8 psi from a s/c to 8 psi from a turbo?


ANSWER: a turbocharger has lag. a supercharger is active at lower rpms. you will get same HP numbers with both but the power band will be longer with the supercharger.

[Savin]

Yes, boost is boost, that's why i said a supercharged ZE was similar to a turbo'd one, people make similar amounts of power, correct?
But What I'm saying, Kego probably wants to SC the stock SOHC. Wouldn't it make sense to upgrade the internals to withstand significant amounts of boost for prolonged periods of time? If he were to use the the motor he has now (without upgrading internals), don't you think it would be wise to keep the boost low?
With a car only having 88hp stock, then putting on low boost (to protect it) it wouldn't see much gain. I can't really remember, but didn't the old turbo kit for the SOHC only put it to around 130hp? Or am I just thinking nonsense? I'll look back at older threads and post what I find, that would give a general idea on power...I think.

If my thinking is wrong, then it is...and I'll just delete my posts later...

[onlytrueromeo]

Your thinking is not wrong, why would you supercharge a stock SOHC I don't know.

Kego's posts have been annoying me...maybe its just me.

[Savin]

Ok, I did a little searching. I don't like to, but luckily I posted in the thread I was trying to find.
JWT turbo'd a SOHC on a stock bottom end. Got it to run 11's.
I don't know what else to say in regards to SC'ing a SOHC aside from the sound the belt and SC make.

Meh...

Turbo better...

Depending on what Turbo and supercharger you are talking about, psi does not equate to power.
The amount of air that the compressor flows does.
A bds 6-71 flows much more air than an eaton m62.
It also depends on which type of supercharger. a vortec style supercharger has a linear power curve, where as a roots style has the much more desirable instant torque..
Even though they are both types of forced induction its comparing apples to oranges.

You guys also forget the paracitic loss from a supercharger. It's like an A/C compressor, your alternator or your power steering pump, it requires power to driver the supercharger, while a turbo is literally free power, just using the energy from the exhaust gases to spin the turbine.

If you make 8psi on a turbo or 8psi on a supercharger, you'll make the same HP at the crank, but from the crank that's where you're whp will be different.

this is some what off topic but much later down the line i plan on doing the supercharger as someone previously said for the sound mostly and the lower end tq because since most of the things im doing to my car is giving me top end power and losing lower end power, but from my understanding you can get much more power from turbo than SC but the SC won't wear on your engine nearly as much and is safer.

NOOB QUESTION:

What about a supercharger AND a turbo? Is it doable? I ask cause I'm not entirely sure how superchargers work. And I'm not asking about just for the 1.6 specifically either. Just wondering.

Possible yes, probable not really.

run a properly sized turbo and youll be much happier in the long run.

horsepower is horsepower, turbos arent safer than superchargers and vice versa.

yes there will be some parasitic loss from driving the supercharger pulley.
But what alot of people also dont understand are compressor maps, and that 8 psi from one turbo to another and from one supercharger to another are not the same.


PSI dosent break parts, Power does.

[projectzemx3]

i know the supercharger is a extra load on the engine which reduces its power, but what are we looking at here? maybe 3 horse? you will make that back with the s/c plus more.

turbo's are restrictive to the exhaust (especially the amount of piping needed to run them in our cars ) that lowers power too....

[projectzemx3]

however the post about the engine only having 88 horse stock so if you added low boost for safety, would only bring it up to 130 made me laugh so hard.

the best power mod you can make out of your b6 powered mx3, is to remove the b6.
