v-mount - why so much?

[dhracer]

As per the title really, what's so special about a v-mount intercooler that makes them so damn expensive? :confused: surely you could take any old FMIC and with some custom pipework have a vmount? Or is that over simplistic? :smash:

[Actual_Ben_Taylor]

Because to do it properly requires a lot of custom made parts.

[dhracer]

Could you elaborate please :thumbs: I've looked at photos and I can't see anything special about the core or piping, it just looks to be a different pipe route - that's all :confused:

[Neil A]

I've always wondered about this too. Is it so you can create airflow which continues post-IC so it creates more of a flow through the core?

[FIGJAM]

I dont think its so much to do with the core, rather you would want to change the direction of the end caps (entry and exit) to get smooth airflow, then you would probably want a custom hard pipe it or use lots of samco and small pieces of hard pipe to get a short, smooth pipe run.

Time is the big cost rather than parts (I think)

[Neil A]

You've still got a 90 degree bend from IC to tubby and IC to TB though haven't you?

[j@wrc]

the cost comes from fabricating one big air channel and tilting rad back etc so from the side you end up with the v shape you need to close the sides off so that the air is forced through the intercooler and rad .

some rads and intercoolers also come with a tilted core so when the rad is laid back at 45 deg the channels in the core sit straight to let the air thriugh il get me crayons out and try and draw what i mean tonight to better explain

kind regards j@wrc

its not so much about pipework route as coolin both more efectivly so you aint got a big intercooler sat in front of the rad they both have a clear air stream

[Neil A]

That 45 degree thing is very cool. Makes a lot of sense.

So is it so the air which has done its job of cooling the core has somewhere to go thus creating a genuine flow as in most IC set ups the heated air doesn't have anywhere to go?

[Actual_Ben_Taylor]

Not that expensive anyway - 2800AUD

Gotcha (I posted too soon :smash: )

Yours and my interpretations of expensive clearly aren't the same :wack:

*penny drops* I hadn't realised the kits include a radiator :wack: - I assumed that you got the intercooler and were on your own as far as radiator, air channel fabrication goes :smash:

Around £1100 for a complete bolt on v-mount setup including the radiator, header tank and everything else seems fairly good value to me...

[dhracer]

...to me too :wack: I'd been thinking that you just get the intercooler for that money :o

[bkvj]

yeah you are being a bit simplistic.

if you just change the piping to make it shorter so the intercooler lays 'flat', you should actually save money, as you use less pipes.

but then the rad is in the way, so you have to make a bracket so it can lay in an angle.

in the end, you just need a bit of free time and being a bit handy with tools and it takes about a saturday doing it all (providing you have all tools and other stuff you need)

there isnt that much in there to make it all work to make yourself one, unless you use it for proper racing and you need the exact right volume bla bla bla (a la Formula one technology:wack:)

[Mikesx13]

Surely you can just DIY it?

£1100 seems an awfull lot for a rad an intercooler and some bits of cut metal unless it's Greddy/Koyo stuff?

[Easy007]

Would you have to use a different rad as the standard one has a cap on the top?

[bkvj]

thought so aswell.

only have to make a bracket (and lets be honest, shouldnt cost more than £30 to make) and custom piping (maybe about £100 in total for all materials),

you should be able to use your standard radiator, normally you use an uprated intercooler aswell but you only buy the core (whats that, £200 new from apex, doesnt ahve to be big!) and maybe a longer radiator hose.

lets say DIY it could cost you £350 to make...

maybe im just completely wrong though!

[Kieran_e1]

evo 4" core , lot's on angle bar , big grinder , couple of leccy fan's

job's a good un.

have a look at Kev's project purplyness thread i think he put his pics up

[mattkeeber]

I'm sure Pip @ WGT charges £1100 for a v-mount set up fitted. that includes everything needed and all the ducting to seal it off and do it proper.

When my mate was there getting his RX7 mapped after a rebuild he was talking to him about a v-mount he was fitting on another car

[kam]

I'd like one some day, mainly cause they look cool :wack:

On a serious note i'll have a big top-mount, want to do everything i can to reduce lag. I think for them to work best you need some good ducting and a bonnet vent.

Couple of pictures anyway:

This my DIY IC set up....
The intercooler tubes on the endtanks are changed so i havent not to much bends. Its done by the local smith company.
Al the order stuff, like the alu plate and bonnet grille I have buyed at the local construction shop.
Now its waiting for the rebuilt engine:cool:

[Butuz]

To do a vmount properly you need to do a lot of fabrication work to make sure that air is properly channeled to both the IC and the RAD. Just doing a Vmount on its own won't work without ducting to get the maximum amount of air to both.

Somthing like that will work!

WOW, these are cool, do you actually notice much difference?

[Ol'_200sx_thing]

id imagine that because there is no obstruction ie rad behind IC, the flow of air would be better for both, but i think its alot of work for negligible gains, but again ive not seen one in the flesh, or read a review, so cant really say for certain, im just using a little comon sense :)

[mattkeeber]

Well with RX7's which like to run hot & where v-mounts are popular, they make a huge difference.

You need to make sure the sides are enclosed tho, as air takes the path of least resistance and you won't get the same effect. With the sides enclosed the air had nowhere to go but either through the IC or the Rad. Incredibly low intake temps and a rock steady water temp

If you don't have a problem with water temps with the FMIC fitted, I wouldn't say it's worth the cost or hassle. You apparantly get reduced lag too with the very short pipe runs, but I can't confirm / deny that.

[MisterAdam]

I can't see how a 200sx radiator would work, would you need some much longer rad hoses then?

Could you not put the radiator and intercooler together (where the intercooler would sit at the top) and that way you'd get the benefit of shorter piping (less lag) and channel the air from the bumper through them both?

*edit* Isn't that what Sumo Power done with their pink R33 drag car? (sort of)

My mates ran far to hot with his current spec (big) he fitted the v mount and it made the world of differance:thumbs:

Rx7,s do put out some heat though:wack:

[Evilchap]

I wonder if Buffy can make this work with my car... maybe V-Mount IC/Rad and V-Mount Aircon/Oil cooler :wack:
