Turbo or Supercharger?

[gotrice93]

So this spring I'm throwing around the idea of boosting my car. My friend told me that supercharging is the best way. The only question i ask is he says I don't need bigger injectors or a intercooler or even a chipped and tuned ecu and ect. But what I'm wondering is what does it take to supercharge a car compared to turbo. Can i just throw a supercharger on and run?

thanks for that link. It answered like one thing i was concerned about and the was the tuning. It said a supercharger requires few fuel upgrades. does that mean a bigger fuel pump and stock injectors or a stock pump and bigger injectors? It still left questions

[gotrice93]

idk why but i only looked at one page. I'm gonna research it more. Any input is great though

I believe that you are suppose to upgrade your injectors but the fuel pump isn't necessary although a very nice upgrade that you might as well do... Or at least that is what I seem to hear on my prelude forums. And as for a tune, tuning is alwaysss a good idea especially if your goin turbo or supercharging

if i were you and i was going to Supercharge, then and there i would get better fuel delivery system parts, and replace belts. Makes sure you have upgraded your air induction and exhaust to with that supercharger putting the engine to work. i have always wanted to supercharge my DA but pretty sure they dont make a intake mani supercharger for a B18B engine. I think GSR & ITR only.

when it comes to sc an engine its pretty much the same idea as boosting. more air means more fuel. you will never get the peak hp out of a sc as you would a turbo. if you run 20lbs of a turbo you get x amount of power. if you run 20 lbs on a sc you get x amount of power, minus the power it takes to run the sc. but a sc has power all the time at all rpms, you dont have to wait for spool, and it sounds better. as far as fuel goes, you need just as much fuel to run 10lbs on a turbo, as you would need 10lbs on an sc. difference is in tuning. your fuel curve is much straighter in a sc than with a turbo cause your always boosting. ingnition tuning is the same cause with x amount of boost you still need x amount of ign retard. as far as how you do it. with a sc for fuel, since it is linear you can just get the appropriately bigger injectors and run an andjustable rrfpr and you can adjust your base pressure to fine tune your a/f, and if at any time boost fluxuates, the rrfpr will add or subtract fuel needed. and for ign an msd ign box will do wonders. but a good piggyback or standalone will always be best. my .02

The air induction, fuel system i can do myself and there is a really reputable shop for exhaust here where i live. The reason tuning was a big question is because the closest town with a tuner is probably spokane. So i don't want to have to trailer my car to spokane just for tuning.

drive it nicely untuned, not gonna hurt it.

Spokane is 250 miles away. So if a 4 hour drive on the interstate classifies as nicely then that wouldn't be bad. But I would have to climb up and over 2 mountain passes and i don't think there is any way to climb nicely.

When my brother charged his Civic, he didn't have any issues with fuel cut, running too lean, nothing. He didn't have to have his car tuned. He basically bolted it on and went. He had the stock injectors, stock fuel pump, stock everything.

I'd rather have a supercharger than a turbo. Less moving parts, less room for failure of some sort. You can use an intercooler, but it's not necessary. He said the people at Jackson Racing were super helpful and their customer service was amazing. He said if he ever charged another Honda, he'd go back to Jackson Racing

well if you add more air and not fuel, then your gonna run lean and mess things up. you can run 5lbs of boost on all your stock stuff and just rais the fuel pressure. but when you start getting over 8lbs you need bigger injectors and timing adjustment. running a sc car on all stock stuff untuned is just asking for trouble. i know plenty of people that run dry nitrous and theyre cars still run. well it wont last too long and something is bound to happen. it may work, its just not smart

hope you have 4-6 grand to spend... and yes it does cost that much to do right.

[gotrice93]

I have found JRSC for like a grand for my car. idk how 4-6k

[2.5i]

Oh ok I must be wrong, cheaper is always better when it comes to forced induction... I mean Honda guys prove that almost everyday

[gotrice93]

I mean i dont see why i need to throw 4-6k into a supercharger to get started. If i was gonna throw that money into it i might as well do a swap

[2.5i]

Well, clearly you didn't your research or have read what I wrote. If you want to waste a lil over a grand why not paypal me 1200 bucks. Look on the brightside in the end you be out some money, but your car will still run.

I think he was only running 8 psi.

yea supercharging is more expensive than a turbo. a decent sc is at least 2-3k. and if you run an intercooler, you can up the power without upping detonation, thats what the ic does. if you run forced induction, run an ic unless your looking for a descret lightweight low boost sytem.
