Forgive me for being a total idiot but what do u mean by supportive mods? We talking forged pistons and stronger heads? I'm aiming for about 330-340.

 

Whenever I've been out for a good run and when the the car is stopped of course, I frequently put the flat of my hand on my TMIC and it's always stone cold. Does this mean it's working well or am I being overly simplistic?

 

motorola i think it is more teh injectors, induction kit, headers etc than engine internals

 

Thought the MYOO injectors were ok.

Induction kit I kinda get but if I'm doing that might as well do FMIC

 

Trevor, next time you're over here we'll do a simple test. We have an infra red temperature tester. We'll test the car as soon as you arrive after a good run. Then leave it with the bonnet shut for 30 seconds [ traffic lights time ] and re-measure the temps Then we'll have an idea of the intercooler core temp and potential heat soak.

As for your times at Santa Pod. I'd be far happier for you to arrive at the start line stone cold, bonnet up and so on and then give it the beans for 13 seconds, rather than arrive with the bonnet shut and intercooler temps through the roof. [ This is for top mount I/c cars only before you all jump on me ]

Neither way is great, or recommended, but in the long term cold is doing less harm.

Hi,

Oi !!! B*GGER OFF!, you have to be in a special club to bait Bob..............

 

FWIW, I have a Hyperflow TMIC fitted on an MY03 , which is significantly bigger than even an STI8. With a charge temperature gauge fitted (supplied and fitted by Harvey) I find that that sitting at the lights with the engine running produces a slow rise in charge temperatures - around 2-3C per minute. However, with the engine turned completely off, the temperature rise rate is easily double that with engine on. I guess the constant draw of cool air with the engine on is helping to keep the charge temps from rising too quickly.

In reality, this means if I pull up to a temporary stop (eg lights) with engine running, I'm more than happy to push the pedal to the metal when I get going. However, if I've been parked up for a few minutes, I would hold back for 2-3 minutes until charge temps are down.

Obviously, these problems don't apply to a FMIC but living out in the sticks with the nearest traffic lights more than 20 miles away, the TMIC (with all its drawbacks) works well on the road for me, especialy as I've got a bit of a 'thing' about throttle response If I were to use the car on the track however, it'd be FMIC all the way.

Should also add here that I run a 321H and the car makes 415bhp / 380ft/lb of torque on Zen's rollers (renowned for giving conservative figures). Indeed, a recent dyno run, Paul commented that he's yet to see a car running an H on a 2L engine producing as much torque. Of course, maybe I could get a little bit more torque using a FMIC, but my point here is that for ordinary road use on the open road, it's not all bad news for TMIC users (runs for cover )

 

I'm on board for that, thanks. I'm always wary of heat soak, always have ice in the intercooler spray water at the Pod. My TM always seems to stay cold and after 3 or 4 really hard pulls but as you say the core temps may be different.
See you in the New Year

 

Ice is for Gin & tonic or Scotch - not intercooler sprays

really david? i can see the logic in the thought so why not

 

oilcooler, nocklink, decent set of gauges, gearbox and clutch are way up on there limit at that sort of power too, also maf is extreamly week on that year (mine blew 2 during mapping before being replaed with autronics, the nock control is also extreamly good thing to have). brakes and suspension also arn't gonna be the best for that sort of power. your also gonna be wanting to run it on vpower.

 

Hiya mate. I really would love to see what torque your car (obviously a good example) would produce with with an FMIC though!

As you know, I have a smaller turbo the good ole VF35 and mine (before the Simtek and *ahem* boost increase) was making 343 ft lbs, up from around 320 ft lbs (on a cool day) with the standard MY99 TMIC. But the really noticeable thing was how much more aggressively the car came on boost with the FMIC. Not sure whether that was the 5 degrees of extra ignition advance Bob dialed in with the FMIC, as the torque increase alone doesn't seem to correspond with the bum dyno. With the Simtek, Bob turned the wick up to 1.4 bar, so probably even making a bit more torque now..... If only Simtek had a Delta dyno feature

Just me offering my 2 cents as usual

 

5 degrees of extra ignition sounds very nice matey and would definitely give you some serious boost (no pun intended!) in the kick in the back feeling Are you based in bonny Scotlandshire or did I imagine that? If so, I'm up and down to Glasgow quite a bit at the moment so you'd be more than welcome to come for a spin in the old girl and see what she can do with just a TMIC FITTED

 

Bugger.............

how much is it to join ?

cheers

Bait away, no hard feelings. The article doesn't test a STi8 TMIC anyhow.

I don't think there was ever any doubt that if you are into dyno queening, then a FMIC is the correct choice.

However, if you're interested in having a quick, responsive, moderately tuned car on the other hand...

Never been interested in dyno figures myself, but would rather the car go quickly.

2.35ltr build underway which will be using one of our FMICs

 

so bob do you have your own workshop then? sorry for sounding stupid but i alwayds thought you were just sales / internet sales.

 

Putting my pop corn away for a minute & getting back to the OP's question.


Are these the tests you are on about?

AutoSpeed - Top-Mount Trial - Part One

AutoSpeed - Top-Mount Trial - Part Two

 

Bob:
Now that you have come back, deal with the unfinished business on post #11 which was the cause of your departure.

This is a slur if it is aimed at me and Jeff. I have no arrangement with Jeff to advertise my products whatsoever and I have not asked him for any recommendations but he did see my extensive stock level, after your slur about photographing the same intercoolers outside. These were still outside when Jeff was here but not now as they have been sold. You had been claiming biggest stock level for weeks prior to this. Obviously another fanciful marketing claim on your part. Jeff had the misfortune to total his engine in France. He is a fellow Subaru enthusiast and I have offered to do his rebuild over a period of time at advantageous rates so the charge to him is not a drive in drive out price and we can work on his car when time permits. Simple as that. Helping someone in this way may seem alien to you, apart from your having no workshop but my arrangmenet with Jeff/Alcazar has no other caveat and categorically I have not asked him to promote my goods or services.

I have tested the STi 8 top mount intercooler thoroughly and it would still be on my car if it was the best option. When it was fitted it only had to perform as well or nearly as well as some of the pundits were telling us. As said by Splitpin elsewhere, anecdotal evidence is not good enough and there is no substitute for careful testing and tabulating the results.

Trevor: When I had a brief drive in your car I did not consider that on the road air charge temperatures from your top mount were a major concern. The place to measure the temperature on your top mount is where the short stub goes to the throttle body on the flat surface on the bottom of the intercooler at the throttle body exit. While temperatures on a brief test drive were acceptable it would be interesting to know what temperatures were achieved under full power on a rolling road. I am sure a front mount would improve your car and result in more ultimate bhp but from what I saw it would not be a high priority and I would want to get to the bottom of your apparent lack of power and when API have their rolling road operational they have all the facilities to do that.

 

hi Bob sorry tried to pm you but your in box is full mate so thought i would try you in here

as i said in the post and i mean no disrespect with this but i was under the impression that you were only sales via the internet and did not have a workshop or premises to carry out work / fitting / testing etc of products.

if possible i would like to come up and say hi and see your place in the new year as i am picking up a new impreza (cross fingers) this weekend and will be looking to make some tasteful improvements to it so it would be good to see what you have, what you can offer etc

kind regards

steve

 

Ho, ho, don't hold your breath for an invite mate

 

I think this is heading towards STICKY territory......I'm opting for it to be made a sticky in the tech advice section..

Hybrid FMIC for me from Mesiour Harvey when funds and time permits.

 

Ok I get the oil cooler,clutch gearbox and gauges. But what's knocklink and Knock controll

 

WHY NOT, if he has had the time to put into testing the inytercooler theory and has a customers 2.35 under way then surely bob has the facilities and a workshop / garage ?

i wil await bob to reply before judging him or bob feel free to pm if you wish

cheers

 

He didnt say he was doing the build - just that it was using one of his FMIC's.

 

One of his FMIC's is??? a Hybrid? hmm or was he refering to a TMIC of some kind?

 

i cant belive the top mount costs more than the front mount, i thought it would be the other way around.

 

oh right sorry i miss understood what he meant, thanks for that

cheers

 

Hi Steve, yes that is correct, pile 'em high type outfit here. No workshop.

Still welcome to drop by. Contact details can be found on AZTEC PERFORMANCE ONLINE STORE - WHOLESALE PRICES DIRECT TO THE PUBLIC

2.35ltr build is on my own car. Been around Imprezas for some 9 years now and my comments are based on personal experience and the views/advice of the most accomplished mapper around who maps the car.

Seen far too many FMIC owners wondering why they have been shown a clean set of heels by a car with 100 odd bhp less and a TMIC, so seek to address some of the sales spiel that goes on about FMICs.

Yes, we sell plenty of FMICs, but ring up and ask for advice on a moderately tuned car and you're likely be advised that a secondhand STi8 TMIC from here or ebay is the best way to go for a road car.

Have been to a fair few workshops and so-called tuners over the years, so can recommend some tried and tested places if needed as there are far too many cowboys out there.

Indeed, there will be a list of recommended tuners and workshops available via our website soon
