DOnt really know TBH, I havent Dynoed or tuned it yet, so I'm not gonna throw numbers around that I can't back up :)
 
For the SA guys, I should be going to Mallala again this Sunday 13 Sep for the Modern Regularity :)

That's a fair point. It'd have at least be pushing 250kw though, or around that. Cause isn't a 2GR around 230?

Was just asking cause I'm still tossing up between a 2GR or 3SGTE when I hit my opens

My guess is that it will dyno around 220rwkw. 2GR with gouky headers and better intake runs around 185rwkw.This is approx 92% of the advertised 202 kw crank figure.Toyota rates the supercharged 2GR at 241 kw so using the same maths (rough I know) we can expect 222kwkw (near enough to 300 horsepower). Will be interesting to see the results while you are stil running the factory ECU. Kw figures are fine but the real story in the torque with the TRD Aurion providing 400nm and provides magic grunt as Lucas has now doubt already experienced. Some interesting figures here to whet your appetite http://au.toyotaownersclub.com/forums/topic/26861-djkors-aurion-rev-2/page-18 . Tasty quarter times too for the TRD Aurion and the MR@ is some 350 or more kilos lighter

Running 13s in an Aurion is crazy. I'm sure the MR2 will take flight with the same running gear haha

I agree, low 200's KW sounds about it I think.
 
On the track, I found that the torque was signifincalty helping pulling me out of the corners linearly and smoothly, and that's why the car felt "easy to drive hard" (to an average driver like me), as you can simply feel what's going on and what's about to occur and you can act accordingly.
 
I'm still running stock ECU. Still hoping that someone cracks it soon, otherwise I'll be going for other solutions (i.e. Haltech, AEM, etc..). However safety items will most likely come first.. (anyone got info on the most suitable Velo seat that's going to fit in SW20 and provide good head clearance?)

Do the safety things and run the engine standard. Spend money on track time and improving driver skills. Easily the best bang for buck when it comes to improving lap times and you should also retain reliability. I still have 4 seconds to shave off at Wakefield (set by another driver in my car who is now swapping out his turbo for a 2GR) so it is obvious where the weak link resides. Look forward to seeing you at MTC 2016 in January along with the other 2GR SW20s that are being built at the moment.

Thanks for the advice mate, that's excatly what I'm doing. 
Currently looking at a HANS device, Velo seat (that fits properly) , and a roll cage (not liking the cost of a car trailer though :(  
Also planning 3 more track days before MTC.

Glad to introduce this latest addition, Velo Podium II Carbon. At only 7.4Kg (inc. Billet Alloy Side Mounts) this should help a bit. (Passenger seat has been removed too).
 
Going tomorrow to SimonBuilt to talk/plan roll cage :)

So I had a chat today to Simon from SimonBuilt and Lance from Walker Chassis regarding full roll cage. Hopefully I'll get around to preparing the car for it (removing the interior inc. sound deadening etc..) in Mid Oct.
 
And today I purchased this sweet 6 Point Harness. Another Velo product. Not that I can do anything with it until the whole safety system is in place (seat, harness, HANS, and rollcage)
 
Next is Hans+Helmet, and then the full cage should be the last piece of the safety puzzle :)

Today I went out to the track for Modern Regularity. I don't really care about the competition tbh, all I wanted was seat time!
I participated in 4 out of the 5 sessions.. I was only able to get 4 clear laps in total during the whole day.. The track was just full! it was the biggest turn out they had in a long time apparently..
 
Anyway, my goal for today was to do 1:23's . I was very happy to manage 1:23:97 during the last session :)
The car can do faster times, the only limitation was the driver! lol
 
During my last lap, I noticed the stock water temp gauge went up a bit, so I backed off straight away and used what's left of the lap to cool down, and the temp went down straight away.
I checked the engine bay in the pits, no coolant leaks or anything.. I'll have another look once cold. The temp during the hour long drive home from the track was normal.
 
Couple of photos from today, including my latest engine lid sticker :)
