[juicyjay]

wow please post vids!!!!

[Sileighty_85]

Thats Bad Ass hows the driveability?

[SleepySR]

The throttle response is lightning fast , it honestly drives like stock but with a lot more power . 1st,2nd,and half way 3rd thru is useless. I do a lot of drift events and the torque is perfect anywhere in the rev range a blip of the throttle will induce oversteer.

[Prok0]

looks sweet, but i bet gettin to that oil filter is gunna be a pain in the dick now. haha

anyways, cool build.

[singlecamslam]

hmm, is this setup smogable?

[Shift_Dr1ft]

I second that ^^^^^^ if it is smogable build me a kit and I will buy!!!!

[Nikeboy355]

Great graph and looks like very well done engineering... I'm impressed...

But the 5 psi graph seems a little low on power... I made 157WHP 157WTQ with a stock KA... I'm guessing the cams might be the limiting factor...

Was that KA rebuilt or what was the mileage on it?...

[ManoNegra]

what blower is that btw? looks pretty sweet

[drifter_for_life06]

thats pretty sick....vids please

[!Zar!]

hmm, is this setup smogable?

No it's not carb legal.

No, it's not smoggable any differently than a car with an SR or a turbo ka setup.

[blackrms13]

Was that KA rebuilt or what was the mileage on it?...
+1 on that information

[SleepySR]

Engine has 190,000 on it , last weekend I started to serious blow by, so a new short block is in order along with a mildly ported head , and degree'd S13 cams.

smogable? I don't know where i live 95 and older is saftey inspection only :p

[SleepySR]

looks sweet, but i bet gettin to that oil filter is gunna be a pain in the dick now. haha

anyways, cool build.

I installed a Oil filter relocation kit so no trouble there

[SleepySR]

blower is from a frontier/xterra

[Mangudai]

I love reading stuff like this. Video please..

[murda-c]

I want to buy that.

[KrazyS13]

I'd love to see a video as well!

[southerncross]

ive been wondering if anyone was going to do that. . . i used to hang out at unstable hybrids back in the day and jason was working on a supercharger off a 3.8L pontiac motor, but i dont think he ever got it running.

awesome idea man, glad somebody tackled it. i'd take that over a turbo any day of the week.

[xplicit240]

are you guys planning to make this? id be pretty interested.

[BlueKpS13]

cost? just wondering, ive gone over it a couple times in my head and i though it would seem expensive but i have never been completely sure

[SleepySR]

As far as producing these we"ll see.

At this time we're still in the prototype stage. During this first run of CNC parts were trying to finalize the design as bullet proof as possible while keeping it cost effective . Due to the intricate detail in the CNC file, the cost of the CNC running time can be rather costly. With that being said, were trying to find a more cost competitive shop because CNC time for these parts are costly, because more time in the machine = more money. When, and if, the product is finished we will then determine if it'll be cost effective enough to try producing the parts in limited quantities.

Sorry this is not the answer you probably wanted but if i quoted you a price now I'd be lying to you and myself. Right now there is just too many variables that are unknown and nothing is solid yet . We don't have finalized machining times and material prices based on volume. Pricing TBA when we know all the details. Feel free to check back in 2-3 weeks and hopefully well have more info on the details.

[mcdonis]

thats awesome!!!!

[Shadowhunter]

Awesome, finally something unique.Not bad power made too. We need vids for sure.

[D.Bo]

wow thats really badass!

[SleepySR]

Fresh engine is off at the machine shop in the morning , new coated pistons and bearings , degree'd cams and a mildy ported head are in the works.

I also have a H20/meth injection setup going on along with a high / low boost controller switched inside the car.

should get me close to 300whp!

[murda-c]

How much would i have to pay for the custom stuff? haha

[Devil Man]

wow man looks good.. keep us posted.

[pahaf]

wow thats a first time i actually see a supercharged KA24DE

[pahaf]

Great graph and looks like very well done engineering... I'm impressed...

But the 5 psi graph seems a little low on power... I made 157WHP 157WTQ with a stock KA... I'm guessing the cams might be the limiting factor...

Was that KA rebuilt or what was the mileage on it?...

how did u get those numbers? cause all i see is that stock KA's get something like high 120's and low 130's

[Wake]

Man me and my friends have been talking about that exact setup for about 3 years now, we just dont have the resources to pull it off. Its really good to see that theres till some innovative minds out there with the patience to pull it off.

+1 from me

[!Zar!]

Khmerguy618 had a supercharger setup that he ran for a while.

Probably will post up pics and info soon.

If not I will.

[ManoNegra]

WagDatto is piecing together one too
there are vids of a few on youtube aswell...

[inuyasha3466]

Nice! The set up looks pretty good too.

[240_fun]

that is absolutly sick... if you can get a kit in production i would totally sell my KAT for it

[SleepySR]

I started to do a mild port job on the head tonight (cleaning up the ports and casting marks , gasket matching) before the head joins the block at the machine shop.

weisco 9:1 std bore
rings
Nissan OEM main and rod bearings on order .
picks tommorrow when i finish porting the head.

[S14_Kouki]

very nice I would of expected alittle more torque but its really cool to see what supercharged ka can do keep up the good work.

[SleepySR]

I also expected more torque than horsepower . I wish I dyno'd the stock motor to have a base line to go buy . New engine should be in by next weekend , and my friend is going to do a before and after on his S13 in the coming weeks with a similar set up.

[homeeninja]

how did you make your adaptor or did you use thomas knight kit b/c i talkd to him awhile and his whole kit was around 1300+ w/o charger or is yours alil cheaper than his pm me soon need to know asap

thanx man

[Gorilla Unit 33]

I was on Ka-t.org a little bit ago and no one could ever remember seeing a dyno sheet at 300whp for a s/c ka, but i thought that would be sick! i have always been intrested in s/c my car but without seeing further proof of 300+ capabilities it really turned me off. Theres not a doubt in my mind that with a mild port job, pistons and some 248's you could reach that.... and if so that means that i'll be making plans for my car come december, even though my own car hasnt even hit the streets yet this summer lol. Why did you choose to use the q45 tb instead of the n60 that i see alot of people running? or is it basically the same? also if your going to cnc would you be making a smaller pulley as well? the only puleys i can find are all aluminum and i would much rather use one with a steel main sleeve and maybe and interchangeable outer pulley?

That's enough of an answer to have my subscription to this thread.

[VQMaxFan]

very nice.

Ill have to show this thread to a friend, he has the plate and s/c and most of the parts he needs to s/c his car. He has just been lazy to getting around to it, mebey this will help him get off his ass lol

[CT93S13]

I would definitely be interested in purchasing this upgrade for my KA!! keep up the good work!! decent power and torque gains no doubt!! Looking forward to hearing of your progress!!

[stealthsr20]

i have two ka's and i sold one with an install, just waiting for the car and one for play time. This is a grat idea because i love the power band that it makes. keep us posted on your updates and maybe a video of it running.

[SleepySR]

thanx man

We started this in Nov, of 2008 every thing is cnc'd from 6061 T6 aluminum except the alternator/tensioner bracket which is made of 7075 T6 because of some Solid Works FEA testing. By using the 7075 T6 the alternator/tensioner bracket is 13 times stronger than needed. We came up with our own mounting and brackets for this set up based upon some modeling/CAD we did in Solid Works.

As far as pricing there are to many unknown variables to date , but were are hoping to be more affordable than Thomas Knights kit.

As for as us producing pulleys , at this moment we don't have the capabilitiesor contacts that has a CNC lathe to make our own pulleys.

The reason behind the Q45 TB and Q45 MAF , is to free up inlet restrictions . On a supercharged set up your drawing air through the intake piping not forcing it through like a turbo set up . Imagine trying to breath with a coffee straw , then breathing through a 7/11 Slurpee straw . By using these parts we gained 2-3 psi with out swapping the pulley.

[SleepySR]

Block is at the machine shop 9:1 wiesco's , arp rod bolts , OEM bearings . heads getting a 3 angle valve job w/ new guides and seals. Rotating assembly is going to be balanced . Pictures of the rebuild when it comes back from the machine shop, and i get all the parts back from the powder coater.

[Devil Man]

get some pics and specs of the sc and the plate and brackets while its off the motor and what not. i want to see what this all looks like. keep us posted.

[Gorilla Unit 33]

Understood now :) good thinking, i would have never thought of that. What did you do as far as tensioners?

[DrftKid(^_^)]

WOW!!!! That's so freaken sweet I wish I still had my KA..nice work that's so unique. I bet u really pop eyes...lol

[Grantspec]

Any updates on this thing?? How did you run your IACV?

[Ceepo]

Wow this is awesome, did you ever sell your s14 i saw it for sale a ffew weeks back...

[WISH ONE]

I have one of the superchargers sitting around somewhere from when I worked at nissan... maybe ill screw with it finally lol

[DailyDrivenS14]

who did your plate to mount the sc to the mani? I made some and wanna know if it works lol got the whole setup just havent installed yet because we are trying to fogure out how to do a belt tensioner...

[jzepol1985]

you can find superchargers starting at a $100.

[chibo]

Any updates on this?

[DailyDrivenS14]

well i can make the sc to manifold adapter plate if anyone needs it. I would really like to know if this is one i made to know for sure that there are no issues.... Get back to me Sleepy

[xxxblingxxx]

I am intrested in the pulley system specs. I got charger off xterra. I need plated for manifold and spec on pulley set up .

[fromxtor]

Sleepy is that Kyle's car?

[s14unimog]

That's a pretty awesome setup you've got there and props for the Solid Works skills; Life is better with Inventer though ;). One thing I wonder about is why haven't we seen centrifugal units yet. Typical excuse might be that they are all too large but Rotrex makes them quite small and with lower HP consumption through the belt system than your typical rotory lobe or screw type....

If you are looking for some CNC help, I can quote you 3 axis work.

[Persona]

Yes Inventor FTW.

Looks like a fun build!

[s14unimog]

^see this man knows

[drivens13]

He sold the car to a friend and now the car is back together with a new heart.I'll try a get him to post about it this weekend.

[DGTRIALS513]

Total Cost? I am really wanting to do this. I was interested in a RB20 but this is slick!!!

[Devil Man]

so weak if thats true..

[MambaSic]

Then you figure it out, with your money, and quit whining. Ok? People do stuff for a reason, Money, not because some kid on the InterWebZ is Gonna give him a smiley face or some dumb shit. Get real.

This isn't exactly rocket science. Well in a way kind-of. But if you want something done right you have to do it yourself. Didn't your mom ever tell you that???

[DGTRIALS513]

Damn dude you should calm down. I just wanna know a rough estimate so I can make a choice on the winter project. I use to work at a machine shop so I have a decent machining connection. If it gonna be super expensive then I'll stick to the RB swap. And yeah Im sure the tolerances of the bolt positions have to be pretty tight to get it right the first time. Plus I don't think anyone can help tune that setup around me. I could be wrong though. There is a reason it is a rare build! Plus I am pretty lost on the methane/ water injection. what does that do exactly? Seen it on another setup on you tube...
Thanks

How the heck to you use a cockpit adjustable boost controller with a supercharger? The only way to adjust boost is changing the pulley sizes.

Updates with fresh KA please!

[crazy_kat_matt]

this is tight. cant wait to see vids.

I'm totally down for some super custom electromagnetic actuated 2 speed hydraulic clutch with a high boost pulley on the end of the M62. flip a 2 or 3 position switch an voila!

[s14unimog]

Changing the blower speed is not the only way to control boost level. Its common to see a bleed valve on setups with a blow through style MAFS. Ideally you would measure your engine belt speed and find the P/R and desired CFM, given a certain percentage of loss across compression, and decide on a pulley ratio to achieve this output. The bleed valve gives you the opportunity to change the blowers output without affecting the belt/pulley dimensions

Nissam MAFS are not up to the task of handling pressure. Subaru, Mustang or the awesome 85mm - 97mm ABACO MAFS would be the ticket to handling the boost.

You could control boost through a MAXFLOW Mondo (or your fav adjustable bov) on a blow-through, as long as it installed (far before) before the MAF. By the time your sort out all the ideal distance between components, the intake plumbing would be a mess... Not at all impossible though.

I'm considering a centrifugal compressor... TopMount Turbo setup may be for sale.

[s14unimog]

I've seen 350Z's holding boost on centrifugal setups; its not impossible but requires a little attention.

It you look into Rotrex, hit me up I get dealer pricing....
