Half way there, soon my bably will burn some rubber like she suppose to do.
also I'm becoming hungry for some ricers.

 

okey dudes, I came to the point of thinking of tuning.
Becouse it sucks were the ECU is, it is very hard to piggy back, so I will try to think of a way, actually calculate.
but I cannt find one thing I need to know, thats what are the flow at what psi are the stock injectors.
people who knows, this would help.

I repeat,
flow of injectors????

i know, i know but i finally got some pics for ya. how's the prototype going? you got it mocked up in your car yet mounting?, belts? come on we wanna hear an update.... actually we wanna "SEE" an update. pics are worth a thousand words

 

Cool, basically same desighn as in my car, but has more space. Thats even better.

I have sketches, that look kind da wierd. but I do have a moke up from carboard, how ever the Whiphle does not have W75 yet. just promises so I cant reaally make one from sheeat metal.

So I just sit tight and wait.

I already selected the belt but still final be from the SC it self, some idle pullies.

Basically nothing has to be mover or drilled, just some parts removed like air box. most of the stuff stays in place as they are.

in the end, the only way to tune the car is with piggy back, that be cost efficient.
it uses also Intercooler to prevent detonation and create much more power. I think I found a good way but I dont know yet so I wait a bit with that too. I might implament "Sub Zero" Cooling in it, but that could lead to more air leaks that might be accepected. So again We wait with that too.

 

once you start getting really serious and begin making parts you might want to think about getting some patents. p.s. whats the time frame your looking at for yours to be done a month 2,3,4 ?? Did whipple give you a date for when they are going to ship you a supercharger??

 

I was thinking about patents. Dont know yet if I get any.

and Whipple did not give me any time frame, they said its not ready yet, and thats it.

 

hey you need to ebay a used m90 try talking to this guy http://cgi.ebay.com/ebaymotors/GM-SU...QQcmdZViewItem

good luck and hurry up

 

I second the hurrying up...but don't hurry too fast, cause then I won't be able to afford it when you sell...or if you put one aside...then that will work too...haha

 

hey kak i got a question what is it that blows the eninge say a 5psi pushing say 1000cfm or a 25 psi blowing like 500cfm, i guess what im asking is is it the cfm cramed in there or the psi cramed in there that blows the engine up if both what would the limits be for a n/a engine i know you cant tell me exactally be any thing would be nice. thanks

 

Short answer:
The limit is the strength of the components. Whatever Audi designed them to handle is what they will handle. This number I don't know.

A longer answer:

CFM = volume/time
engine size = volume
rpm = 1/time

CFM = volume x rpm : i have left out all the conversions. Once you know how much CFM you need then you multiply that by the PSI to get a mass. The more air mass you have the more fuel mass you will have. After ignition that large mass of stuff will create a larger more forceful explosion. This force is what moves the piston. The limit is what force the piston can handle. Lucky for us Audi dosen't design them to run at its maximum. This is what the S/C takes advantage of.

sorry i don't know any numbers.

The compression ratio of the piston also limits how much boost you can add. Say after all the math you find you need 200psi of air at ignition. Stock pistons are say 10:1 ration (made up #). You then would want 20psi of intake air. Since ambient air is at 14psi you would want to run 6psi of boost.

Also note that the PSI of air in the intake manifold will add stress to the seals, valves, and the blower itself. Then you have to consider the piston will compress the air further.

If that dosen't help just PM me and I can explain it better. Right now I need to sleep.
