Intercooler pipes

That is correct.

And then I hae noticed the following two equations:The first equation describes the overall heat transfer that occurs.
Q = U x A x DTlm and also:We also have an equation for checking the amount of heat lost or gained by the fluid on one side of the heat exchanger (ie, just the turbo air or just the outside air):
Q = m x Cp x DT
Too much for me thank you. Easy out for me , I have bypassed the intercooler.

LOOK MOM, No Intercooler 😀 😀 😂 [/img]

63mm in and 76mm out would be good. Inlet speed would be around 200km/h and exit around 135km/h which is pretty good.

Why did you bypass the intercooler??

Gary, give us that formula. Would like to see it. Seriously very interesting and hope to learn from that.

So back to my intercooler thing Gary, have you worked it out? Freddys Water meth works well got alot of power out of it. looks cool as well.

Gary I bypassed the intercooler because I inject water/meths. I dont exceed 1.3 Bar. Up to that level, more than enough cooling. If you go dual nozzels, then perhaps more boost. I only use one nozzle 175ml/min before TB. Your next question going to be that the intercooler will assist in the water/meth effort. Yes, with higher boost perhaps. I dont need that.
No lag for me in 2nd , 3rd and so forth.

1. find the amount of air the motor is consuming at peak rev or boost.

1800cc = 0.0018m3
5500rpm = 91.667rps
1Bar boost = 2 x atmospheric intake

SO... (0.0018/2) x 91.667 x 2 = 0.165m3/s

2. now work out the speed in the pipes.

m/s = m3/s / area of pipes
m/s = 0.165/???

3. now convert from m/s to km/h

km/h = 3.6 x m/s

Guys this is the very basic of equation, disregarding friction. If you want to work it out correctly you need to know the radius of the bend, pipe material, etc and that takes alot of time and serious thinking.

Guys the cooler is in, my boost is at about 0.5 bar in 2nd at 3500 revs and then I am not pushing it so it is about the same as it was normal, if I put foot it will defenately boost full at this revs because previosly it did the same, will let you know what the dyno improovement is as soon as I have it so then we can see if the cooler really works and how ifficient it is.

What cooler did you have on befor?? Hows the lag, is it noticable??

I am a bit scared to put my new cooler on, dont want anymore lag. Do you think there will be a big change from 600x200x63 to 600x300x76??

I was on the standerd stuff before so no I don't think you will see a difference on the lag, I have got a 600x400x76 on now and as I said lag doesn't look like a problem.

The guys that know better than me, I can not get to the Dyno to redyno after the intercooler swop, the car has a unichip in that was mapped, will the car be hurt if I drive like this for a while till I have the time to go to a dyno or is it safe, I have pushed it a bit, there seems to be no problems, jerking etc.
