It's a manual.

it's got no power before 3k rpm.

I've tried it with my RSM, if you launch at 2k rpm, i always seem to get 7.5 sec 0-100. I launched it at 3krpm and i got 6.4.

Hmm. I launch at around 4.5k... but lately my tyres have been crap, so now around 3.5k...

Sometimes when i'm really going for it, i launch around 5.5k... but that's very rarely, as i still want to have a clutch at the end of it.

Vlad, what I found with the RSM's, is that for comparisons you always have to use the same spot, and that area has to be as flat as possible... cos a slight not noticable down hill could add like 0.5 of a second... you probably know this, but just in case... :wink:

Thats the same engine Ford used in the ST24 Mondeo, good engine that likes to rev. I'd take the ST24 over the other cars that share the engine. Euro Ford, slightly more refined and has its chassis sorted out a lot better.

Well, while we on the subject of under rated, I line up 2 WRX at NT where theres no speed limit, i beat one WRX on the first gear then lost by second, & the other one only beat me after third gear, although i kill him offline (sh*t driver).

The thing is both WRX owner though i had a turbo running, & you should see their face when i told them is a N/A. PRICELESS :D

There's a Japanese spec version of this engine as well, which makes more power than the 'export' versions - around 140kw I think (its a 2.5 remember). There was a guy over here who transplanted one into a Mazda Eunos 500 sedan (medium sized sedan). He did some mods to the engine, such as upped the compression, some more aggressive camshafts and fitted a Link computer, plus the usuals of exhaust, filter, etc. In the end it was making 250hp and he had a best 1/4 time of 13.8 8O - pretty good really. I raced him on a racetrack once, and he was faster than my old twin-turbo 6A12 VR-4 :oops:

Anyway, I read somewhere that my FTO has a stock 1/4 time of 14.8 (someone feel free to correct this if it's wrong) - whether I can actually get close to that is another question... I'm definitely planning on trying at some stage.

you two r the first FTO owner I know that ran low 15's :)
Our last West Aussie drag night saw the following times:

14.832 - Leigh's GPX, exhaust, intake (plus unknown X factor! :))
15.211 - My totally stock GPX
15.485 - Vlad's GPX, exhaust, intake.

We're going again in a few days. Watch this space for results... Or just ask Teania & Kaveman, who are coming along.

- Rich
...and this time Leigh got 14.81 and I ran 14.84. :)

Leigh's all time best was 14.6-something a few months ago... which is nothing short of spectacular for a GPX. Damn fine work!

why is it some engines that are compared to the mivec feel like they give out more power but are quoted with less power???

Simple the FTO produces 147KW at a sky high 7500RPM. So how often are you in this zone? Rarely! By the time you hit peak power it will be time to change gear. I guess the way Mitsubishi achieved this 147KW figure with only 2 litres is to design the thing to rev. But a common problem with small CC, NA, high reving engines is usually a very peaky power band. A good example is the S2000, small capacity huge RPM, hence big power from such a small engine. And what did most people who drive them and magazine writers say? It feel like a civic when not revved.

So comparing KW's is one thing but really only take it at a guide. You can have a 4.0L that produces 147KW, but because of its bigger capacity, requireds less revs, and usually these bigger capacity engines produce peak power at a lower rpm, which gives the drivers more time to utilise every bit of engine power. A 4.0L engine of 147KW will have significantly more torque than a 2.0L engine as well, which in turn helps a lot with accelleration.

The 1.8 SOHC might of produced 83FWKW but a lot of factors come into play, you cant just compare KW's!

I guess people to overestimate the strait line performance of the FTO. I guess becuase its a grey import, its strait away put in the category of GTO, Skyline, Supra, etc etc. They machines have greater CC's and more often than not have forced induction. In its class the FTO is a great car, but a lot of people dont see it like this, they usually think, the FTO is slow because my 5.7L is faster or Supras are way faster.

ive excepted the fact that a lot of cars are faster than my FTO out there, im never said my car was fast. There only so much a 2.0L NA can do, and believe the FTO deserves credit in its class.
