Tuning turbo time!

[arc]

i'm a chef, and at work we have aluminum pans which are quite thin but we also use a lot of thick based stainless pans. they're not cheap, but they do work very well.

with regards to boost pipes, this is how i see it; the engine bay temp is going to be higher than the charge temp. if you have conductive pipes, you are going to get heat from the bay into the pipes - not the other way round. so you want pipes that don't conduct well. if you want to cool the charge, use an intercooler for that - it's what it's for, and it'll do a good job

so basicaly the best boost pipe work will be plastic or silicon

got my exhaust done! its perfect. and VERY quiet. there is no noise inside the car what so ever
out side it is deep but not noticeable (the sound would not draw attention.) and no rasp or rattle at all :slayer:
i put a sock over my dump valve to take the edge off it.
the car feels much smoother.
get a photo tomorrow... its to dark now

sounds really nice
mine is quieter still and it is restrictive though,

 

[craigb244]

yeh this is straight thru.. no mid box or cat... it actually seams sounds louder in the vid. its so nice driving a quite car though!

 

[Slosei]

iv got middle and back box
systems 2" up untill back box where it reduces to 1-3/4 inch which keeps it quiet
thinking about having a screemer pipe though would be funny

 

[craigb244]

wow! yours must be silent! gotta get rid of the restriction at the end tho!

oh i have just hit 70miles on £10 of fuel... lights just come on still got about 20miles left my car has NEVER been this good for months.

not silicon... you dont want the pipe to expand / contract under different pressures!

 

[craigb244]

have you seen how much the silicone expands tho... its fack all really but maybe a bit at high boost. I never got the induction stuff done today as the bloke never had time. he started at 10. finished at 6! he did a really good job tho. even welded plate onto the downpipe so i can weld onto that to bolt onto the block. even he reckons the turbo needs more support

 

[arc]

it expands a lot when you're bunging ~2bar through it and you have a lot of it.

 

[craigb244]

true... i added that above before you posted .
but again like i said before about conductive metals. the induction parts are SOOO short on the cento i bet that even going from a super cheap pipe setup to a ultra expensive set up. you would not pick up anything... weather would have more effect then what can change along a foot length of pipe

true ture, but i want run a pipe from the back of the car to the front

true ture, but i want run a pipe from the back of the car to the front

And boosting at 2bar...good effort

 

[craigb244]

ooooh! my old idea!... fair play!

2bar?? thats a lot!

 

[arc]

nooooo not 2bar on this car.

it was the smart car that ran around 2bar. https://www.fiatforum.com/gallery/data/500/hazel_boost.avi

ooooh! my old idea!... fair play!

2bar?? thats a lot!

it was my idea before it was your old idea

 

[craigb244]

haha yeh but i was the first to bring it up still very interested in it tho.

 

[Slosei]

dont know if with using the bigger turbo will make it louder "i think" it might
got to work out where to sit new blower and manifold design now

 

[Brooky]

Does anybody else have the 'page not found' problem on this thread, or any lenghty thread

 

[arc]

yeah but not on this thread, i've got threads set to max replies per page (ie this is only page 14)

 

[craigb244]

im only on page 7
but yeh i think on page 17 or something it does it... used to do it on the megasquirt thread all the time

talking of megasquirt... rewire time tomorrow

 

[Brooky]

im on page 19
