Summer almost turned into Autumn before I got Supra MOT-tested again, but for 1,5 weeks I've been learning to drive it again
In the beginning of August I finally got the car ready for a dyno run. First miles in the car were quite nervous, since I've pretty much built this thing myself so anything could have gone wrong...But almost all the issues I had were about Ecu-adjustments. No leaks, no loose bolts, no dropped parts...
Anyway, dyno went pretty well. With only 1,15 bar boost pressure we got 518bhp/640nm out of it. You can imagine how excited I was when graphs showed numbers over 500 (which was my goal originally). With the goal reached we decided to leave it there since I was 100% sure that this is already enough power after 2 years of not driving the Supra
After that it took almost two weeks before I got the MOT-test finished. But when the papers were done and car passed without notifications I was pretty stoked
To be honest, it's quite brutal thing to drive. Clutch is loud and tricky to use, most of the transmission rattling comes into cabin, 2-way LSD makes cornering quite interesting, hell comes loose then throttle is fully opened...But it is just the way I wanted the car to be, so in that way this build has gone just as planned. The feeling it gives when turbo screams and tires lose traction in (at least) first, second and third gear is rather mind-blowing experience for a first timer.
Since this car is never-ending project, I already have plans for coming winter:
- Stiffer spring for wastegate => boost up to 1,4-1,5 bars
- Possibly gear-dependant boost control
- More grippy rear tyres => Yokohama AD08R, Toyo R888 or similar
- New front upper and lower control arms
- New stabilizer links for front & rear
- Spare engine block building: Forged rods, pistons, bearings, billet crank main caps (will probably build new engine for E85, so 10:1 compression)
- Oil filter re-location kit, OEM placement for the filter is pretty damn annoying and messy
But winter is still some time away, for now I will just enjoy from working Supra for rest of this autumn!
