$400 supercharger setup working at 5 pounds boost

[S133P3R]

looks like a fun set up, you may have shed light on a pretty easy power upgrade for the KA guys. best part is, the SC comes off way easier than a turbo manifold and all that.please post pics of the set up once you get it taken apart, if you do.

It gives a very high pitched noise when revving, but nice performance for the $$$

im not an expert or anything. but shouldnt that thing blow without any fuel management?

no, no, it'll run just long enough to make a video or two. Seriously, though, that's an awesome setup, just throw some 370's and a walbro pump on it so you can keep it around for a while.

[S133P3R]

an AFC wouldnt hurt either, lol.

[casper82]

would this http://cgi.ebay.com/ebaymotors...ories

on the injectors ? what the stock cc . the smallest ones i found where 440cc,,,,, i dont know what size to get

[HoosierSX]

hmm......im impressed

The stock injectors on an SR20DET are 370cc, KA24DE is 240cc

I like how the gas tank flew open haha

370cc SR injectors would require tuning. I highly recommend the Walbro fuel pump though.

I would just get the Walbro, and a FMU (raises fuel pressure per psi) then retard the timing 3*-5*and your good to go.

With the Walbro, 370cc, and an AFC it would cost more, and require time to tune. Plus in my opinion it isn't as safe or as good in the low boost condition you are running.

Do some reading over on the KA-T forum. Lots of information over there.

I found that pretty funny myself.

[casper82]

that sounds right. cool the Fuel Management Units are new to me ,but i get how they work.. so stock injectors,walbro pump,and the Fuel Management Units should keep the motor running safe

[S133P3R]

any good references on FMUs DMan II-40?

[casper82]

ok i just the walbro pump and a fmu.. so i should be good i a week or so

[AZ89two4Tsx]

Make sure you pick the right FMU. They're not all the same.

[pj]

why does it sound like a helicopter or whatever?

this made me lol...hard.

[S133P3R]

the sound made me LOl pretty hard and that was the first thing...like if i were picking up friends in this thing...GET IN DEH CHOPPAH!

[spooled240]

nice "KA-S"? how much power do you think you're putting down?

[S133P3R]

spooled240:check this meet out, you should cruise down to the OC for it... gokarts too./jack move

[spooled240]

^what meet? lol

[S133P3R]

^what meet? lol

sorry...zerothread?id=450033

[OutToWinPAHC]

nice "KA-S"? how much power do you think you're putting down?

It would be a KA24E - R, R stands for supercharger, but its added so add the -

[pj]

truthfully, this makes me want to rebuild my old ka24E....so i can supercharge it and destroy it again for real.goodtimes myep.

EDIT: OMG s133p3r thats the best arnold pic for that quote! i salute your humor sir

[Warped161]

def watching this thread. i like this idea a little more than a ka-t. seems much less expensive, now cant you change the pulley to get more power? also is 15lbs from this the same as 15lbs from a turbo? i know that might be a dumb question.

[HoosierSX]

i'm sorry for answering for the op but i would recken..ka24e - 140hp5lbs of "supercharged" boost - roughly 10hp per pound of boostand 10hp loss from turning the superchargeri'd say about 180hp

he can get a smaller pulley but will probably be good only to about 8psi. boost is boost but you have to weigh the cons and pros of each.the turbo charger takes no power away from the engine, but the supercharger provides more of an instant boost, no lag.

10hp loss? More like 30% loss, this is the argument between turbochargers & superchargers.

Turbo: theres a lag and youll have to replace it before you would have to get a new SC BUT it doesnt take power to make power and its not limited

Supercharger: cost power to make power, on average [30%] loss BUT the power is instantaneous and supposedely the unit will last forever.

I owned a supercharged Grand Prix before my turbocharged S13

any good references on FMUs DMan II-40?

Everything I read on them is in the KA-T sections. They are generally associated with low budget (aka T25 turbo) builds. I think there is stuff in the stickies over there but I don't have any references off the top of my head. Sorry

[spooled240]

^ppl have used the 8:1 vortech fmu with good results

turbo's and superchargers both take a ton of hp away from the motor but the gains are much more. I remember reading an article on a drag supra with a giant single turbo on it and they claimed that the turbo produced 600hp but it drew about 100hp or something..i can't remember the numbers exactly but it was pretty mind-boggling. Usually turbo's tend to be more efficient but laggy...superchargers have instant boost but tend to be less efficient than turbo's.

Older metro buses around LA used to have superchargers and turbochargers. The SC took car of the low rpm with instant boost and the turbo took it from there after the bus got moving of course the turbo's where probably as big as a CA18 engine but it worked

[motoman399]

this is pretty cool for a dd. never realized how cheap you can get those SC's for. have fun with it

[Mangid]

Wow dude, that's pretty damn cool.

Why did you speed the video up though?

[S133P3R]

added 10hp -duh!
