Thanks for clarifying that. I always thought that at high speeds the air is deflected over the scoop.

SC46, Grimmspeed TMIC, 420bhp. No hint of anything like heat soak on the road. Vs stock it has no more lag and is relentless. Awesome road car.

Tidgy

on a fmic you'd prob see 460 then

and no melted engine to boot.

Parply

It wasn’t tuned for max power but max power band. Not something a FMIC gets you. I can still put my foot down in any sensible gear and get a response. Awesome road car ...

Tidgy

That makes zero sence, lets reduce the power so it holds peak longer.

Who on earth came up with that? wouldn't be the person who sold you the tmic would it by any chance?

1509joe

Negligible difference in spool at that level of tune.

Tidgy

wont be any unless the setup is poor

Parply

So the driving experience and performance is entirely dependent on max BHP ? And I specified the mods not the tuner ...

Didn't want to say that couldn't be bothered with a debate with some know all c**t

Tidgy

not it isn't, however what your saying is setting a turbo to max at 1.6 bar (for example) from low revs to high revs, where as it might make 1.8 bar and drop off to 1.6 if set for it.

In other words your setting it up for the lowest boost it makes so missing out on anything it might make above that boost level.

You will only be using a couple of thousand rpm when your giving it welly anyway because of where the revs go as you shift gears.


Short version where ever you got the info on running it that way, you need to look elsewhere for better info

Tidgy

Parply

Don’t know it all. Did a lot of research. Tuner agreed with some helpful advice that I was wise enough to take. I now have a rock solid road car that has a wide power band and great power and performance beyond stock. I love the car and so does everyone else who has been in it. Just wanted to point out that a good tmic can be part of a decent upgrade

If mine wasn't SORN'd at the mo, I'd let you try it.
No lag, due to a Harvey Smith trick up-pipe, boosts from 2500rpm

FMIC with scoop left in place to make it look standard (apart from the glaring FMIC, of course!) - what's the general consensus on routing the air flow? Leave it all as is, route the air down towards the turbo with a custom shield setup, something else?

Cheers

Tidgy

i left mine as is

iMook

Do you not get a load of crud around the engine bay?

Tidgy

nothing more than usual

dont forget when tmic is in place anything taken in would block that anyway

makkink

And witch fmic are the best for a buck?

iMook

That's the unanswerable question. Depends on the rest of the set-up. The better quality, the better the airflow, but if you're just looking for a FMIC for cooler air and a bit more bhp (mapped in), then a Japspeed at £299 will be fine.

You can spend mental money on a FMIC - it all depends on the rest of the set-up as to whether it's more than you need, if you know what I mean.

what's the general consensus on air intake filter placement for a frontmount
the ones I've seen have the cone in the engine bay, I assume to shorten pipework?
Trev

iMook

This challenge is the routing of the pipework to the throttle body (or from the turbo, depending on which way the pipework is routed). If you remove the air box, you can easily get it through.

This is the Mishimoto one, just by way of example, with their filter option. I can't see a way of fitting a FMIC with the stock airbox, although I'm sure someone somewhere has done it

You could go the cold air intake as an option, but it's a tight squeeze inside the wing.

thanks for that. So placement of the cone has in most cases to be somewhere in the engine bay. I did wonder if it was to offset some lag as in the pic the pipework to the turbo is quite short but I see the options are limited.
I would expect if the car was stood in heavy traffic for 10 minutes the intercooler core would be heat soaked to a certain degree as the turbo pulls quite a lot of air even at tickover which could only be from under the bonnet. A top mount with a cone in the engine bay would be a total disaster in those circumstances of course.

Tidgy

get lag out of your head, its a myth that you'll ever notice it at all, your talking fractions of a second.

you can go wing mounted and take the intake away from the hot engine bay completely.

No mater what intercooler you have, never boot it straight after coming out of sitting in traffic for a while

trevsjwood

iTrader: (2)

thanks for straightening that out for me

Tidgy

no bother, its a myth that keeps poping up buts total horse crap.

I went from 330bhp on a tmic to 390bhp on a fmic and gained 100rpm on my type r so i can tell you from experience its total crap

iMook

You get massive lag on the 1980s Audi Ur-Quattro - that's because of the turbo (it's massive) and the fact that it's 30 year old tech and takes an age to spool up - that's all lag is.

By comparison, the turbos on the Scoobies is small and spools up quickly.

I run a FMIC on my track toy and there is zero lag.

SmurfyBhoy

Very true

Here is an example

My car HDI FMIC, RCM Cone in bay

Que for 10 mins to get a run down the quarter and this is how my intake temps sat
