Been playing with the idea of getting an aps top mounted intercooler for my99 classic ppp'd scooby, got dawes, sports cat downpipe etc,
any one got any experience of em ? is it worth it ? will i get any increase in bhp or performance????? im not to informed on the intercooler so any advice is appreciated
cheers

FWIW, I gather the pressure drop over them is significantly lower than the pressure drop over an OEM (by 1-2psi IIRC). This has to be a good thing; less power wasted moving the air. The turbo has to work less hard to make the same amount of boost, therefore doesn't heat the air so much = lower charge temperatures and a little more power and safety. Alternatively, you could hold perhaps another 1 psi boost at the top end = more power but with similar charge temps as before. All in theory.

As for experience of them - I know of someone who has fitted one to a MY02 and is apparently pleased, but I haven't seen him since.

Don't know if that helps, there'll be someone along with more knowledge than me in a bit, I'm sure.

Found it great with the TD04 - as hades says, the pressure drop appears to be lower (well, that was my guess as well! ).
I've changed to a APS FMIC now (even better ) so was getting round to selling off the old TMIC, if interested...

what would scooby do

Nom, YHM !

thanks lads but it still isnt that convincing for around £500 !!

Hi Nom,

Email in your profile is dead - I'm also interested in buying the APS tmic, please email me. Thanks

Dowser - the emails working OK, but big chunks of the Internet are down this weekend (some SQL virus thing) - if you can't get a mail to me, I probably can't get one to you
Will be more awake tomorrow & get mails off to all who've asked Hopefully the 'net will be back up again by then too...

jees girls hijack me thread why dont yas ??? erm...for sale section !!! lolol

nom

Sorry

£500 makes it not a very good bang-for-buck change, no. Depends to an extent on the state of your old TMIC to a point... but there is a noticeable improvement. The effect of changing it felt - unsuprisingly - rather like upping the boost. After sticking it in, though, I was quite happy with the outlay/performance 'ratio'. The car just felt quicker/more responsive, and I was happy with the increased safety margin it offered.
Hope that helps a little!

Nom, what difference did you have with changing the top mount for a front?

Did you notice any lag with the front mount over the standard intercooler?

nom

TMIC to FMIC - certainly no increase in lag, but this I imagine is rather turbo dependant!
Car's a bit 'perkier' all the time, and is a lot more critical of the exhast flow (ie the car's now capable of a lot more power, given the chance!). However, no mapping has been done yet to take account of the opportunity for extra advance, etc. that the FMIC offers, so I'm missing out on most of the (power) benefits (although have the safety ones for now!). The mapping has to wait until I get the rest of my life sorted out

Absolute Shower

Sounds good nom. Are you still selling the APS top? How much for it and does it have any fin dents?

I think I'll be happy with just the top mount and slightly bigger turbo for the WRx, since I don't want stacks of lag and then monster grunt from a big turbo - I don't use the car's potential enough on the road to warrant it.

nom

I'm not getting into the selling thing here again (sorry paul!) but just because it's good for others to know, the fins on the APS are seriously solid. You'd have to stand on the thing to get them to bend, I reckon . No, I haven't tried!

FASTER MIKE!!

what are they like for running big(ish) boost something in the region of 1.4bar?

cheers mike

nom

It all depends on the turbo, really. If the turbo is mainly working as a heater at 1.4bar, then you want to turn the boost down, as however much boost it's producing it's not going to be an efficient charge. If, on the other hand, it's happy & efficient at that point, the TMIC would be fine. But a FMIC is always going to do a better job. You can effectively edge towards a FMIC by having a very efficient TMIC, but it's only going to go part of the way!
There's also the question of where the 1.4bar comes from - if it's caused by a squirrel stuck in the exhaust or if the turbo can actually keep that boost level (high flow) going. That effects the flow rate across the 'cooler so how efficient it needs to be about it...
I'm not helping, am I?

FASTER MIKE!!

i was thinking along the lines of a hybrid turbo of some sort with ecu mods. running on the stealth idea, and its alot cheaper and easier to fit (diy) than a fmic.

mike

eddited to add:-
the 1.4bar was peak

Well, it's certainly better than not having an uprated TMIC at all - I'd have though some sort of uprated TMIC is a good idea if you're going to throw cash at a hybrid. Having said that, I'm less convinced that it will have such an effect with a larger turbo, as the turbo should then be producing more flow at a lower temperature in the first place (even with a lower boost) so the intercooler choice gets less critical... but that's in theory rather than in practice!

Other worthwhile option is the yankee VISHNU topmount

Found at vishnutuning.com - worth a look?

Absolute Shower

Hmm, Vishnu looks good.

APS do a TMIC the same for the new age. It's about 2.4 times the size of the standard job with less pressure drop and rated to 380bhp - I'm getting one!
