Stuck the FC Cab on the dyno a few days ago, the previous owner had the engine rebuilt, ported and chipped.. and its pushing 178bhp at the wheels (221bhp at the fly).. Woohoo, only running half a bar dropping to .3 at the top end, so it seems to be running standard boost, so the chip and port are working.

Its having some welding done at the mo to get it through the mot, and then we can have some track action...

although, i have a suspicion its not going to stay standard for very long

Will try and get some pics and dyno graphs up later

MR2 Turbo, never raced nor rallied?


She's doing well at the moment, well on the road to recovery. Even found a nice man who will give me free bits!

Look forward to seeing it. You can get up to 300rwhp from these without internal mods, we had ours dyno'd at about 280 but have dropped the boost a bit (approx 250rwhp) while we sort a some minor issues, extra cooling etc.
First event showed that extra power is not the next thing needed, even gentle throttle in 2nd out of slow corner just lights up the (sticky) tyres...

I'll be there for sure Depending on how busy the dori area looks when I get there (1st thing in the morning) I might have a bash. I'm registered to, but if all the pro's are there, I dont really want to make a tit out of myself

Nothing wrong with looking/being a tit. I'm semi-pro at it.

Might give it some up the strip (drag, not club) this year.

I'll only be there Monday unfortunately..

Hmm rx7; reasonably well handling sports/GT cars.
Drags & drift eh; nothing like using a car for what it was designed for

Only kidding, drifting is fun; as I said on the DriftWA forum, the first thing you need to buy for a drift RX7 is some "unhandling"

Drags just don't do it for me, unless it is a proper drag car. I ran my race car at teh drags once, it felt like I started a race then stopped before the first corner. My brothel in law runs a 9 second Torana, that would be a bit more exciting.

Not planning on doing any drifting. My car's pretty well setup for track and the tyres are in too good nick to waste going sideways. Plus I've never had a go before and fancy learning with a little more space than would be available...

Drag strip would be more to have a laugh than anything serious. Doubt I'd crack into 11s with my current laggy setup.

whats with the whole 'drift-cars have bad handling' thing? from what I've heard, decent drift cars have excellent handling, and aren't actually far from a normal track setup.

they're just driven differently, thats all.

Most of the drift cars I have sampled have obviously been set up to oversteer far more easily than you would want for normal track work. Most guys go for super stiff rear springs and hard, streched and usually overinflated rear tyres. These measures become less neccesary when you have an overabundance of power though. (over about 350rwhp)

A beginer would probably have trouble drifting a snappy handling car (ie shorter wheelbase and/or low polar moment of inertia), the preference seems to be for more stable or 'lazy' handling cars. I stand by my comment that you need to compromise the outright handling and grip of an RX7, an FD even more so than an FC.

You're dead right about being driven differently though

Not having tried a drift car myself (and driving a Subaru) I can't speak from experience here so you may well be right, its just every time I've heard drifters discussing set-up they're trying to get as much grip and traction as possible, in order to pick up enough speed to carry into the next drift. They may have been running more power though.

maybe cptsideways will drop in and educate us some more.

Apparently the FDs steering rack is too slow to be a great drift car.

Getting the back end out in a controlled manner isn't too hard though even with less then 350 ponies

Yes but there is a difference between controlled oversteer

and drifting

Yup Mostly a matter of degrees...

Car set up for track or 'grip' driving (as the dorifters call it)
converts HP into acceleration.

Car set up for drifting
converts HP into smoke
