Yes I have seen 500+ WHP on the TMIC I am using on my car with out using methanol injection. I don't see how 600+ WHP with the methanol injection would not be possible.

I have this on my 99 Impreza fits great and fills up the entire opening of the hood scoop. I currently don't have any heat wrap on either the up pipe or down pipe and have had zero issues. I'm currently running 22 psi and 380 WHP once I get a larger fuel system (fuel pump, fuel injectors, fuel lines, fuel pressure regulator). I will be running 26 psi and hopefully 450WHP on the TMIC when ever I get the money to do so.

Are you American by any chance? Its just i see WHP figures quoted a lot by our american friends rather than bhp figures and have wondered how you measure this and arrive at the figures you do. Some seem way off from the figures we arrive at in the UK.

When you say WHP i presume you mean wheel horse power, ie after all transmission losses ,so the actual power put down onto the tarmac? If so the average transmission loss on a subaru is 21.8 %. That means this 600 whp car with top mount would be around 730.8 bhp (power at the crank).

Most of the information I get is from Tuners and forums from people who have had their car on the Dyno and posted results. I don't see how these numbers are that farfetched.

Yeah I'm American, you caught me. We usually measure this from a Dynamometer I'm not sure how accurate these figures are from the Dyno since everything has to do with correction factors and everything.

im a member of nasioc and I have to say most of the big power cars run front mounts as they do over here.
ask any tuner and they will recommend fitting a fmic for high bhp cars.

I'm not looking at pushing more than the 548 BHP on a TMIC. I love the fact that I can push that much power in a TMIC keeping it sort of stealth like with out have a larger FMIC sticking out like a sore thumb.

I agree with this and would never say to run a TMIC for higher power.

548 bhp!!!
what would you call higher power???

i believe one of the lad in the RB320 club has got around 500 bhp from a top mount but thats not a standard tmic. I believe its a chevron tmic which is larger amongst other internal changes.

Over here cars are also power tested on dynos. From what i have seen they run the car then let it coast measuring that resistance. They deduct that figure from the first figure given while on power. This gives the BHP figure. Or they now the transmission losses % and deduct that from the power figure. A lot of the figures i see quoted as WHP on american websites are what i would expect the bhp to be. I'm just wondering if people quote whp just because it was measured from the cars wheels on a dyno and not deducting the losses. Some of the figures ive seen are so different from what we see here that i wondered whether your horse power units were different from ours. Like our gallon or ton is different ?
I took the 450 WHP and calculated it to brake horse power, lol. I tried to not to use wheel horse power.
I feel like I need to learn the automotive speak all over again over here. I feel like such an outsider.
Some days I wish I wasn't American.

Lol, Don't you boys know "Everything is bigger and better in good ol US of A".
I'd of thought heat soak would be a big issue, especially in summer with the generally higher temps over there.
Looks like a quality bit of kit though, and not desperately over priced either, when all things considered.
Awaits John Felstead to show me the error of my ways.

I was running 441hp/ 480lbsft through my AVO top mount with water/meth injection, this from an MD321H which is a 400hp rated turbo. I've now fitted a MD321T which is a 450hp rated Turbo and mapping is due end of this month. The AVO isn't as big as some top mounts and is now 6 years old.
A good topmount with w/m injection is as good at keeping charge temps as any frontmount but then again not as good as a frontmount with W/M.
It's amatter of choice.

your just too stubborn to fit a fmic trev.
hope your engine build went well

Who needs air con it saves on weight. This was the picture I took after a long install and it was late waited til the next day to install the battery.
Yes it is a Forge recirculating dump valve or what stupid Americans call a Blow off valve.

So your saying your car is 381 hp, ie power at the wheels, so around 464 bhp, ie at the crank ?
If so what is the spec of your car to give this power? From that we should be able to work out what figures we would expect from a similar car here in the uk.

Not saying your wrong mate, just taking the opportunity to answer a question i have wondered for quite some time having an america scooby fan on the forum.

yeah that sounds about right with the wheel horse power to brake horse power.
well if you couldn't tell everything is US spec

And to answer your other question, . personally i have never seen E85 for sale in the uk. All our fuel in now 5% ethanol by law. most of us run our cars on Shell V-power 99 ron. No idea what that is in mon before you ask

Sounds like you have done a lot of sensible mods mate. What turbo are you using? edit, just seen it in your list.
