my step father has a dream

[CRyan]

Well then, it's been awhile since I've talk to anyone on here - so hopefully all is well with everyone.

Anywho, I couldn't really figure out WHICH forum to put this in, because I do believe it is somewhat out of the ordinary. But it is happening to a KA motor, and it is recieving psi.

Well, my step father has been a speed freak since his teen years, and has brought me up the same way - - - and he is now a distributor/technican on world known Procharger. Now, the idea here is if he fabricates all the hoses and piping for a procharger to fit onto the KA, and send the blue prints to Procharger, they will make the parts and send a low boost Procharger (10-12psi) for free. Granted, i don't have my 240 he was planning on doing it with anymore - i still want to hear your opinions. He also deals alot with MoTec (avatar) where he can get a great deal on engine managment, fuel managment and such. So that is not a concern.

Couple of questions that yes i could go search to see how much psi a stock block could hold - but i'm right now in a hurry to get to the shop.

Thanks for all the information and questions - i'll try to answer any to the best of MY ability (which isn't to to much!)

wow Im surprised not many people have shown more interest in this. I think it might be cause we need some more information for instance like.

What would the cost be for a kit like this?How much HP do you think a kit like this will weild at lets say 10 PSI.

You can also try ka-t.org if you havent yet.

I never the less would love to see some results and especialy if you guys would consider showing some love for the SOHC too hehe.

[TheOne]

max of ~15psi(thats on the point of if no good tune = blow up)

i probably wouldn't be that interested because procharger only makes centrifugal superchargers and i ain't too keen on those, but am sure there's others that would love such thing.

sorry, white and black kids can already go to school together. your dad's dream is a little late

[bige240]

Procharger already makes a kit for the 350z and g35 and a kit that could fit in any jap car. It looked to me that if you got the kit and removed the P.S. pump and replaced it with their pulley, with a little time and effort it would work on a ka-de engine. Just run your own plumbing.

Centrifigul superchargers are not the greatest, the up side is that you don't need an oil feed for a procharger. It would probably be cheaper and better to just turbo the motor or get the eaton supercharger. Don't forget that a procharger is worth more than the car you plan to put it in.

[CRyan]

i know for sure he was planning to put 300 rwhp with 10psi - - - and for all that don't know - procharger is a intercooled centrifugal supercharger that has shown myself and the select few who decide to come to my step dad's shop and have it installed.

Right now we are trying to take the title of fastest street legal car in america with a 90 model fox body mustang. 348, built of course, and procharged running roughly 48 psi. 8.1 on street slicks - - - and classified info on the drag slicks lol.

I don't like centrifugal SC's, for the simple reason that you have infinite lag. Full boost is reached at full rpm. For the price of an intercooled SC kit you can have a nice turbo kit...so for me, the choice is a simple one.

But I'm always down for options. To me the belt/pulley system will be the hardest. Piping and whatnot is simple. A good pulley system with a 8 rib or more belt drive is would be my choice. I'd rather see it run off a totally new crank pulley, with a new harmonic balancer.

I seriously doubt you'll see 300RWHP at 10 psi, the parasitic loss from the SC will see to that.

i also doubt it is possible to make 300hp at 10psi on a KA

On the first dyno session with the bone stock tired motor, 8.8 psi and proper tuning, with stock cams the motor made 295 WHP

this can be found at http://www.pdm-racing.com/features/240sx3.html

mind you, thats with a "perfect" tune, and a turbo, which has no parasitic losses

[WDRacing]

Yeah....thats the gayest thing ever....I'll arm wrestle PDM for those results right now live.....and I'll win.

[Chezedik]

Being from OP, KS, (BTW, Lenexa, KS) is 2 miles from Procharger, and knowing Nico P. who used to work there, they are NOT interested in a KA kit. Sorry.

[CRyan]

well what i was told from mr. summerland - they could use it.

Yeah, for the PRICE of procharger I would get a nice turbo kit too - - - but this is coming to me for free (or supposedly)

well, so very intelligent nico people (no sarcasm there), how much psi (with a great tune - maybe not perfect, but damn close) would it take to make 300rwhp?

and infinite lag? please explain.

[S0lid_Snake]

what he means by "infinite lag" is that with a turbo, you reach full boost at, say, 3000rpm(yes it can be more or less, but bear with me). with a SC, you get full boost at maximum rpm, and no where else. thats my educated guess at what he means

[WDRacing]

By infinite lag, I mean that no matter what you do, you won't hit full boost at any rpm other then your max, thats just how superchargers work, atleast centrifugal. They are driven off of a belt, as speed increases, boost increases. So if you're running a 10 psi pulley, then you're going to see 10 psi at or around 6500 rpm. Where as I can get 10 psi at 2500 rpm with a properly sized turbo.

I'd say a safe bet would be 15, since you lose some power just by driving the SC. You also need a good header and exhaust.

I really doubt Procharger, Paxton or any other company will be making a SC kit for a car and motor that is almost 10 years old at it's newest. It simply isn't smart bussiness. I hybrid kit could be made fairly easily though, you just need the parts.

thanks for explaining - i see what you mean - and like i said - i'm just relaying info told to me. I figured it'd be worth a shot and something different lol.

[Chezedik]

Knight Superchargers has a kit out now, but it uses an Eaton, not a Centrifugal.

[WDRacing]

You forgot to mention that he likes little boys...

[Chezedik]

IDK, it would be great for autocrossing. Then again, so would a small turbo (which would still be more efficient, and much cheaper/lighter).
