two intercoolers=TWINTERCOOLER!!!!!
i was driving to school this morning and had the idea of using the stock intercooler and a frount mount to effectively double the cooling capacity of the system has any one done this? is it possible? when you get a front mount theres no use letting the sexy TII hood go to waste!
Thanks Tony Montana

yeah, the stock one is not in a very effective place. Novel idea but I don't think results would be worth the extra fabrication work or $$ to buy a kit. Also, the extra intercooler may cause slightly more lag.

well think about the pressure drop.
if you also have a front mount and jioing it up the top mount you may intern be heating up the air.
the greddy i have is huge... like 3time the volume of the stock and i have boost hesitation issues from 1-5 pound between 3200 to 4000rpm
the intercooler is basically lots of smaller pipes
so the more pipe you add the worse the lag

The (supposed) advantage of the TMIC is the short pipe lengths. That's the only thing in it's favour. The big downside is heat-soak from sitting over the engine.
So running pipes to a FMIC negates the advantge of short pipes, while retaining the heat-soak problem. So this idea would actually be worse than having either a FMIC or TMIC.

do you know how fast compressed air moves through pipping, like maybe tenth's of a second would be the difference between a front mount and Top mount... if not less time than that... I think the top mount was to save $$$

Surround the whole thing with header tape! Then dynamat it to make it shut up!
(Sorry, couldnt resist)
Nah, insulating your intercooler is counterproductive. The whole point of the unit is heat exchange!
But I know what you mean, (Covering the engine and turbo) you can fab up some extra heat sheilds using metal peices (Insulate with strips of header tape if you want, then weld a screen over it to hold the header tape to the heat sheild) and put them around your engine bay wherever you see the most heat coming from (Turbo, DP, etc)

Lag = How long it takes the turbo to start spooling
Boost response = how quickly you get boost after you hit the gas.
Basically boost repsonse is how long it takes to compress the entire volume from turbo to manifold. Lag is after this has been compressed how long it takes to get to full boost, or desired boost. Boost response is to get to 0 vacuum.

You're making up technical definitions for two common-use subjective terms which are used to describe basically the same thing. There are no measurements associated with them. Lag is simply the delay between putting your foot down ad the boost reaching a point where meaningful acceleration is felt. Lots of lag = bad/slow boost response; little lag = good/fast boost response.

Like you said NZConvertible they're very subjective terms...
I'd like to add I use the term lag to define 'when'(what rpm) the turbo will start producing +ve pressure in the inlet.
Boost response I'd term as being how responsive it feels i guess..
Oh damm.. I just confused myself even more now and I just woke up after a big sunday night out...
...i'm going back to bed.
ps- Your intercooler idea, superstock2, would take way to much arseing around to get working even close to good... And a good engineered FMIC will be better in just about all circumstances than a top mount really.... Especially in 'cruise' conditions.

Sorry I'm just tired of people using these terms interchangeabley, when they are not the same. There are differences. Go to any turbo manufacture and they'll tell you yes there is a difference between the two.

Boost threshhold - lowest spooling RPM
Lag - time between off throttle to on throttle boost response.
these aren't made up, they're from Bell's book.
