What advantage is the 76mm pipes on a intercooler over 63mm ?

Only asking as a RS500 hose reduces to 63mm when going from the cooler to TB (76mm both ends but reduces to 63mm in the middle)

Steve

 

Wasnt that to stop turbo surge or something along those lines. I remeber reading somewhere that the rs500 had something to restrict it to combat surge. Either in the exhaust or as you mention here by going down to 63mm. Then again i could be totally wrong lol

 

I was told it reduces to get under the throttle bracket ?

Steve

 

Anybody ?

Steve

 

Oh no, ANOTHER 10 pager coming up of IF/WHAT/WHYs

Just ring Tony and stop attention seeking Steve...

 

I have

He said 76mm but did not give a real answer, just bigger is better.

I can't understand why bigger is better if the hose size goes back down to 63mm

Steve

 

Steve, i thought you were looking into a new Cooler mate??

Those Spec-R ones Sheady has tested sound fantastic, he's had great results with them....

 

I am, i just don't know if i should order one with 63mm ends or 76mm ends lol

Also if i get the 63mm one i don't have to get new boost hoses

Steve

 

Steve, out of interest have you measured you air charge temps ?????

Steve

 

No, maybe i should do that first

More money to spend

After 3 runs on the rollers mine always loses power, thats why i think i need a better intercooler

Steve

 

I have seen those Spec R ones, they're something else, SO much smaller than ours and do such a great job...

 

Agreed but whats it like in real life on the road.

Steve

 

How much power loss Steve??

 

They really are a work of art m8, but Steve is jumping the gun without measuring his temps first i think.

Steve

 

If i do get one it will be the new Spec-R one

Steve

 

13bhp, but its still a lose

Mike Kirbys made more on his 3rd run than the first 2 runs

Im just jealous lol

Steve

 

Has Mike got a new style spec R jobbie then

Steve

 

Home from work now lol

Mike has a Pro Alloy intercooler

Steve

 

Intercooler spray, water injection ?????????

Steve

 

what cooler do you have and what thickness?

 

Better car

Steve

 

Radtec, think its 50mm

Steve

 

So does the power tail off a little on the road when giving here a damn good thrashing

Steve

 

I dont drive it hard

Think of all that petrol

Steve

 

you wont need any water injection the new spec r cooler is that GOOD.

also speak to pete as regards to pipe size

 

Its the wet season soon so you wont be driving it at all you big gay, so all this talk is pointless if its sitting in the garage

Steve

 

63mm is good for around 700hp.

Mark

 

Thanks Mark

I was hoping someone like you would post a reply

Steve

Just ordered a ACT gauge off Mr Rainbird
