guys just a quick one for you all

on a p1 am i right in thinking the std sti top mount is good for 350bhp?

but

how how high are the new age top mounted intercoolers rated for say from a 02 sti onwards? are there any differences between the 02 and 05 or even the 07 sti's or are they all rated to the same?

jiust was looking to get a frount mount and then need an induction kit, also woul dhave tro cut the bumper around just thought it maybe easier to fit an newage top mount. looking for 400bhp if that helps will the new age intercooler be ok for that

 

As for the 350 bhp p1 intercooler you are right, if you want more best getting the front mount, thats what i intend doing next They also looks the dogs

 

i agree the look very nice, but then i need an induction kit and have to cut the bumper so thought if the newage top mount was good for 400 then there is no point getting a fmic.

also how do top mounts perform on the track, i intend to do a few this year will a top mount not be suitable or are they still ok to use, i know a fmic woul dbe better but what risk would there be still running a top mount

 

top mount will run 800bhp, for about 2 mins then be heat soaked, top mounts tend to make a difference from low 300's. front mounts are better in all cases unless your running as tiny turbo like a base td04, lag isn't an issue.

 

I just removed my Hyperflow FMIC and went back to a stock TMIC on my 2.5 STi and Scoobyclinic mapped it to 341 BHP and I am very happy. No lag now and much more responsive around town. I know a lot of FMIC owners that wish they were back on TMIC. UNLESS you plan to track it and keep the revs up. Then go the whole hog and turn the inlet manifold around IMO. I also think a TMIC is ok on track if the speed is up because there is no such a chance of heat soak. But what would be nice is a big fat APS TMIC....

 

So can anyone give me a figure for when the newage top mount starts to hinder the performance?

And any other views on how the top mount performs on a track

 

T20 manages 400 bhp on a TMIC.... (tough motor !) imho

Yatesy fitted a huge TMIC to his (new-age) and it just got fried by the turbo, he got less DET using an STI top mount, so sold the big one on....

HTH

dunx

 

Just to make things more complicated, although a newage STi may be up to keeping charge temps cool ON A NEWAGE CAR, part of the success is down to the shape of the bonnet and scoop work together to direct air across the IC especially at high speed.
Classic cars have a bit of a name for not providing good IC air flow on high sustained speed runs, so adding a newage IC on a standard layout doesn't help much.

Given that you have a classic car (P1/STi map), want 400 hp and it will going on a track, then the safest option is a FMIC.
FMICs have come down a lot in price over the last couple of years and now rival the cost of a good condition STi TMIC
The installation is a hassle, but surely its a price worth paying to help keep your engine alive.

 

so the sti8 top mount is good for 400bhp then?

As I don't see the point in fmic if the top mount can do the job.

How do the top mounts fair on the track then?

 

that's a fair point, and a point well said.

 

Yeah stevie, it's not so much about the bhp capabililty but more about the safety margins as already mentioned.

With a TMIC, if your're hooning for extended periods, then when you came to a crawl or stop, the underbonnet heat/close proximately of turbo, etc. can quickly cause the relatively small cored - and badly positioned - TMIC to become overwhelmed with heatsoak.

This drives up inlet temps to dangerous levels, so you have to be on your guard to drive away slowly again (to potentially avoid serious detting) until you get meaningful airflow moving back through the scoop and through the TMIC, thus bringing inlet temps down to within safe levels again. A phenomenon the FMIC option doesn't suffer from. The FMIC's larger core dimensions - therefore surface area - plus positioning, see to that... At the expense of some lag, compared to the TMIC.

 

fair point and I take note on all said I will stick with a fmic

 

STI TMIC from an 01 STI onwards should be good for = or > 400bhp, assuming a suitable scoop and undertray is used to maximise the airflow over the fins.

Downside - the P1's bonnet looks sweet in its original form, without the addition of a larger scoop.
