as i have had continual rain all day not enabling me to work on the car i pottered down the motorway to see my stainless supplier and picked up 3 metres of 50mm 2mm wall for the bargin price of £15 lol how cheap is that :icon_bigg
it actualy stopped raining about 4pm so of i went to uncover the car and decide where the wastgate should fit and for once it is going where i intended as there isnt anything in the way wwwwwwhhhhhhoooooooooooo
pics to give you a few ideas i also started to fab the collector link pipes to the manifold

Not throwing stars and daggers from inside your supra, are you? I thought you'd need them hands for steering :evil2:
Steve what kind of lag do you expect with that size of intercooler and the wide i/c piping? I was checking your i/c and it obviously has some serious air capacity. Needless to say that we have totally different setups, I was thinking about that regarding my i/c and piping and I have some serious suspicion of ending up with too much lag induced by the large i/c & piping.
P.S. Yes there are smaller intercoolers than yours that can still be considered large :biglaugh: :yelrotflm

well did you weld up the cut on ur thumb? O btw I forgot to let you in on a secret. The tig like i said was a magical machine but it cant weld flesh back together. gosh.

yannis i dont think the lag is gonna be more than i expected as full boost should be about 5500-6000 as i hope to have 10lb's bt around 3500
as for yours i dont think it would be a problem measure the outlets of the turbos diameter and give me the intercooler pipe size and i will tell you if you are there or not

justin lmao here with a throbbing thumb :biglaugh:
lol i feel your pain buddy. I have too once shared this welding of the thumb together. Hope it gets better soon! I always enjoy looking at ur thread for updates. Hopefully the rain and the bum thumb wont slow ya down!
Ok the turbos outlet ID is 35 or 38mm x 2, I'm not sure as I don't have the turbos here and it's been a while since I last checked them. These two are connected to a two in one pipe that has two 50mm ID legs to a 74mm ID pipe to the intercooler, the core I think is 600x300x100mm (~23.5"x12"x4") then the cold side of the i/c has an 80mm ID outlet that graduates to a 85mm pipe that ends up to the Q45 tb (85mm ID).group a supra said:yannis i dont think the lag is gonna be more than i expected as full boost should be about 5500-6000 as i hope to have 10lb's bt around 3500

Justin that's just dye, he didn't burn that thumb, he's just showing off those "ninja" hands again...:biglaugh:

justin thanks i appreciate the concern based on knowing how it feels
i think the only 2 things that slow me doen is weather and money lol :biglaugh: the thumb aint even a consideration
yannis-supras said:
based on that i dont see it being a problem as it progresivley gets larger towards the tb so let look at this logicaly as me and ian do on many an occassion lol
3.8cm diameter gives you a surface area of 11.34cm
11.34 x 2 = 22.68 cm combined surface at the start point.
the 5 cm inlets have a surface area of 19.63 cm each
19.63 x 2 = 39.26cm
the 7.4cm inlet has a surface area of 43cm so only a slight increase on the 2 5 cm inlets
and your tb at 8.4 cm is 55.41 cm surface area so it is a gradule increase which i think would be ok but check with ian if your not sure
or just want a second oppinion

<throws ninja star at dart board > :biglaugh:
Wow man that's quite some math you did there, still haven't got a clue how you got your results :aigo: :biglaugh: . Doesn't the i/c core size has to do with lag as well as the actual i/c piping length? Come on Ian, quit lurking!group a supra said:based on that i dont see it being a problem as it progresivley gets larger towards the tb so let look at this logicaly as me and ian do on many an occassion lol

yes but as long as it's not to big it will only take millly seconds to compress the air to boost pressue only as they get really big in relation to the size of the turbo (ie 24*12*4 on a ct 26) does lag start to become an issue

!Yannis: Do you have any compressor maps for your Turbo's and an idea of what boost you'll be running?
