[Mk2] [Turbo] Boot mount intercooler

[RyanRs]

Looks good nick! you have been busy! when are you down the shop next, ill come have a wee look..

Good job on the scoop!

how are you going to get about the gap between the IC and the shroud?

[tarmac terrorist]

shouldnt be a prob as long as air flows through & around the intercooler
not shore when i will be back down the shop,but the main fitment should be finished for kent modied at detling show ground next week as it should be on kierans stand

[refo]

if you want the maximum possible efficiency from you IC then you need to box it in.
if you give the air an easy way past the IC then that is the path it will take. thus you will get a lower air speed and flow through your cooler if you dont duct it properly.

i'd want sides around the IC going right up to the boot lid so all the cold air that is forced in HAS to go through the intercooler. the air speed will be kept up by not letting it expand out into the boot area and cooling would be improved by not letting air down the big gap all round the edge of the IC mount.

i'm not the most tactful of people via internet chat, but please dont take my comments as an insult to your work. i'm just trying to help you better your design.

At times like this I wish I had a CAD model of the MR2 I could stick into Phoenics and get some flow simulations going....could prove beyond most doubt then which method would work best....












*if anyone happens to have a CAD model of an MR2 then feel free to send it my way*

oops

[tarmac terrorist]

no thats fine mate comments are more than welcome as i am new to this.. as i said before these are only my ideas & are not really tested(although phoenix power use a similar system)
as for the intercooler there should be a top section to the box which should seal to the boot lid & go right over intercooler but can not make this until i know where the pipes will be running as they my cut across the intercooler

[rossdymond3352]

Did you just draw up what you needed fab wise and send it off to the local fabricators? or make it yourself?

i ask because although i know i can make it i have no where and no welder

also where did you get your piping from? ebay? have you a got a link please mate? i've found a few but the prices are a bit steep for some metal tubing

i worked the measurements out & done some diagrams for me friend & he made then as i dnt have the equipment to do this..
the pipes come from demon tweeks mate

[rossdymond3352]

Cheers buddy

looking good fella!!

i'm still in 3 minds what to do, decent side mount, boot, or CC, i must admit the value for money and bang for buck of the boot mount is appealing!

[refo]

been having a look into where i'd run a pipe run for a boot mount and i now see why people come in over the IC. forgot there was electrics and overflow bottle in that corner.

so i moved the overflow bottle to infront of where the ecu loom goes into the boot and just held it there with some wood and gaffer tape. (just to test it all)

then i moved the electrics about a bit just to make a little more room on the metal. wasnt a great deal of efford but the overflow bottle does look a mess not in the corner.

like we do in the pulsars, i think if i was to do this mod then i'd get a new overflow tank and put it at the front of the bay low down near the fuel filter.

as for good air flow into the cooler. thats a lot harder.
best idea i came up with was to have a mclaren F1 style roof scoop and the F40 style engine cover. suck the air right off the roof and into the cooler.

great wasy to do it but a lot of hard work to get looking nice. also you would lose a lot of rear vission from the rear window. maybe not a problem for some but might bother others.

tried the side vent idea too but the air flow is a mess. 90* from the side to the boot and then again 90* from boot to down into the cooler. a right mess.

even with the cooler stood upright you have to curve from the side roughtly over the rear wheel to the middle between the lights. the flow is better and the rear exit would help draw air through.. but the size of the cooler is the problem then. as this hole is only about 4" high. if you cut the rear of the boot lid up to the flat surface and down into the bumper you could have a more useful sized cooler. and maybe space for a fan on teh back of the cooler to aid draw.

either way its a mess.

the esiest solution i think would be to have a different shaped scoop on the boot lid and have a rear exiting vent between the lights.
i think the lip on top of the scooby scoop is stopping as much air coming in as possible. if the scoop was a bit more open then i think more air could be forced in.

grr i wish i could draw on computers. its so hard putting my ideas into words.

hang on i'll see if i can do a crap sketch to explain what i'm on about.

it looks great once its all sprayed up.

[refo]

ok sorry for the crap drawing but i really am crap at computer based drawings.



i hope that at least gives you the idea of what i'm trying to get at.

i tested the vent the other night & you would be suprised how much air goes through the vent.. if you look at the roof line of an mr2 it dips down at the rear to allow air to flow over the rear spoiler so it naturally flows into the vent.. refo could you post some pics of where you have moved your electrics as very interested... as for the pic very good only prob i can see is the air trying to escape from the engine bay would heat sink the roof scoop ..also if you were going to loose the rear window view cos of this thn i would scrap the boot mount idea all together & mount the intercooler across the rear window & then ad the scoop you drew to that & put a phoneix power engine lid.... im not slating your ideas at all mate just my opinion as for my idea across the window what do you think(it would be like an rs200)you would have very short runs for pipe work..ps would love tosee pics of your boot mount conversion

[refo]

yeh i see what your getting at.

i had another idea a couple of years ago with the intercooler over the engine and inline with the roof scoop. never developed it. seems like i got tied up with one idea this time

the air intake over the engine bay isnt an issue.. much less than the IC being over the engine! you can back it with sticky backed silver sheet and of course there would be the F40 style air vents in the rest of the engine cover.

i would also use the boot area the same way as i would for a bmic install. except i'd just make a hole in the fire wall and duct it out to the gap between the rear lights. that would suck a lot of hot air out of the engine bay.

i once thought about taking the rear window out and ducting from the left T-bar down through the rear window and into an intercooler before the engine bay/at the start of it. not very passenger or even road car friendly.

with a tin top you could do the same idea but take the vent from the middle through the roof and the back window into the engine bay/intercooler etc. i like this idea most but i feel it works better for an NA setup with a closed throttle body setup. sort of ram air effect.
had the same idea but using the rear quater windows into the engine bay area with an f40 style engine cover.

with the IC version you need an exit path for the hot air that has come out of the intercooler. through the boot seems like the best exit while still keeping the lines of the car clean.
you could just have an exit half way down the rear F40 style engine cover but it would add a little drag over the full f40 setup. still less than the standard setup. that would leave the boot free for engine bay ducting


has anyone tried much larger side vents with a thicker and larger intercooler in more or less the standard location? maybe with clio V6 style cups over the side vents.

i'm not doing a boot install, just interested in the areo of the projects.
i'll move the electrics again for you and take some pics. i only moved them so i could see what i was thinking.

[tarmac terrorist]

cheers mate ...you need more hobbys lol

[refo]

building 3 race cars and putting one drift car back on the road is enough for anyone!

just the 2 pulsars is a massive project that will run till at least april from last may!

still i love tinkering with cars

[tarmac terrorist]

you are a busy guy.. wish i had the room & money to have a race car would i love that
