Here is some info regarding the MY08-14 topmount (not that different to the MY15 on) in relation to the bugeye from a US perspective.

I doubt whether it will fit to a RHD car without mods to clutch master cylinder setup.

Don,

Very many thanks. I think it's fantastic to have someone like yourself on here helping people out. Honestly many thanks. Will read through it all when I can. 👍🏼😉

Does anyone have a log of theirs for comparison

Note those temps will be so high because the car will have just done a run and then had to creep round for another in stop start creeping traffic

Also RCM cone in the bay could be swapped for inner wing setup,

It would be interesting to see how high those IAT would go if my car had standard sti topmount,

So i just got back from having it done. It turns out that the car was 374bhp anyway when they did the first run.
Only a slight increase in power but a much better torque curve. He said it was running lean at low rpm, having retardation for det at high rpm and the boost was all over the place. Its the most expensive 10 bhp i will ever buy but worth every penny. Feels a lot better to drive and builds boost a lot earlier. I never had a prob with the power it was the way it was delivered. Well worh the money for the peace of mind he had it in the mid 390s but the intercooler and maf were struggling so dialed it back a bit

that's very useful torque, it'll be good to drive

That was my problem in the first place. It felt like i had to thrash it and im not a car thrasher. Much better now alot more driveable its got the torque alot lower down where it needed to be

thanks but really didnt need any luck at the time ran perfectly well when i needed it to .

Just to comment ...

Standard new age top mount is good to about 450 bhp if only used for fast road, track at 420 using a correctly chosen turbo that will do that level without having to use excessive boost is no problem.

The standard airbox will support 420 bhp using a K & N panel filter again with the right supporting mods ... but if you fitted a Cosworth panel for example it would not

For information the standard MY08 hatch (onwards) top mount will support 500bhp for fast road and occasional track, I have customers in Germany at this level using their stock intercoolers in the is form. And German autobahns do "test" a car :-)

Pat had to pull mine back under 400 on a sc46 due to temps on an sti top mount and i know harvey did alot of testing as far as temps and intercoolers. I really would not want to go anywhere near 450 on a standard top mount thats for sure.

Tidgy the dyno not a good place for a TMIC at the best of time so you may see higher intake temps but for the fast road it's fine for over 400bhp mate,, the clinics fan will never replicate being on the road for cooling...

a lot depends on how much heat the turbo produces which must depend upon the boost it's run and the setup. I've monitored my in/out intercooler temps for a number of years. My MD321T @1.6 bar runs around 125c and the H which was on there previously ran 135c which is very manageable for a topmount. This is using a CAIK.
I have witnessed 180c with the H but that was because of a boost leak, it does show what impact an unhappy turbo can have though.

It was pulled back during road test,,,

Tidgy have a read of this mate not all TMIC are the same. ... http://www.processwest.com.au/produc...ntercooler-kit

Tidgy

There are options, chevron do one but it's about 2k. Sit in traffic and it will heat soak. It's been discussed many many times before now and tested by better men then you and I and they come back with the same answer. Take it or leave the info it's up to you.

TIZERBOY

Your right mate sat for long enough in traffic any TMIC will heat soak,,, but I've got to say I've not noticed with my process west TMIC

Tidgy

Given the price $1100 + import tax + vat your not far off £1500 which you can easily get a front mount fitted for. Uprated top mounts are better than the standard ones but decent ones are typicly more expensive than front mounts. Not to mention even these limit the performance. Fm allows more timing etc even as low as 300 you'll see an improvement going from tm to fm so it's a no brainer. Laws of physics havnt changed since the likes if Harvey smith ran all his tests and clinic back to backed them so i dont geg why you'd want to keep it in the stock location.

a top mount will heat soak if you park it up for half an hour, it wont to much if in traffic with the engine running and it's pulling air from outside the car as in CAIK or standard intake by the offside headlight. If the intake cone is inside the enginebay then the turbo will pull those temps at tickover.
My Grimmspeed cost me around £600 delivered from the states.

Did cost no way near £1500 imported from Wolf Racing in Australia shipping was just under £100 was £690 on my door step

Tidgy

Fair doos, i was just going off the website price. borderline front mount money though still

Did you buy the grimmspeed hood splitter too ??

TIZERBOY

iTrader: (1)

Yes but NOT everyone what's a FMIC Tidgy,,, they sell millions of dollars worth of Grimmspeed and Process West TMIC's in the US and down under mate,,,, why because they work...

trevsjwood

iTrader: (2)

no just the cooler, I have the STI hood and splitter. I think it all worked out at around £650, £/$ was better then.
Trev

TIZERBOY

iTrader: (1)

Will work so much better with the Grimmspeed splitter mate the STI splitter don't cover the whole surface of the cooler,, with my Process West it came with a splitter that covered 40% more than my sti one... also seals against the cooler really well...

ok thanks I'll look into it.
