I was planning on getting the PS4S next year some time as well! I hope they are worth the insane price

As for the tire, I couldn't be happier. The ride quality is amazing. It's totally silent on the road but still gives meaningful feedback to the steering wheel. I took the BRZ to an empty parking lot to do some doughnuts and was amazed at how well these break traction when desired. I punched it in 2nd gear and it just broke free as smooth as can be. Then when I let off the gas it locked back to the road perfectly and without tail spin. A perfect 360. These tires turn in aggressively. It took me a little while to get used to them as I tended to turn into corners too fast. But once I got used to it, they require much less effort when entering turns. It makes the car feel much more nimble and light on it's feet. This is the closest to driving a motorcycle as any car I've ever driven. On dry roads I can still break traction but now I have to really mean to. 1st gear still breaks easily just by punching it. 2nd now needs a little encouragement. Let the revs hang a bit and then drop it into gear and it will spin in 2nd but not for long. The acceleration is amazing. When not hooning around and just driving casually on the interstate, they ride very quiet. I can make lane changes at 70mph the same as if it were at 30mph. It's instant and secure... I don't feel all the little groves in the pavement through the steering wheel. That part is dampened quite well. There is no road hum at all. On wet roads I have yet to hydroplane. Driving at 60 during a heavy downpour and I noticed no drifting or wheel jerking when hitting puddles. I only have a week on these tires but so far am loving them. They handle the output of the Cosworth quite well. Best tires on the market. Best supercharger on the market and best affordable sports car on the market. Put them all together and you have a true sleeper. |

So what's going on with Cosworth? Are they stopping aftermarket parts production, or just to the US? Can't find Cossy engine internals now as far as I can tell.

They pulled out of the aftermarket for now to focus on other projects. Probably proper racing technology which will yield them much more for them.

Hi guys,
Some prep before the installation was done yesterday All neatly packed (I'm suprised once more how much you can pack in this trunk) I've also visit a dyno to get the "before" graph, but I'm not sure about the results. It was something about 220HP, 215NM. Can't remember the precise number, but I'll post the pic of it for You guys to check it. The guy was dyno'ing on 5th gear and said it was at the weels (sounds like "at the crank" numbers to me). It was around 10 oC (50F) outside. Or maybe the the dyno was hp-happy :P |

Just wanted to throw some pictures out there. A few weeks now with the new tires and the BRZ is running very smooth. It idles so well that sometimes I can't feel the engine at all. The smaller pulley was a good investment. It really made the supercharger come alive. Now that we are getting some cold weather, it's been good to see how the tune does when it's down near freezing. So far no issues at all. Cold starts are smooth and there are no engine dips when accelerating. I think for my last project I'll look at installing a catch can. Probably need it with forced induction. Don't have any real complaints. So have some nice pictures...

Hi guys,
Situation update after the supercharger installation. First 400km (~250miles) done quite gently. I want to take some time for the ECU and all the machanical parts to settle in, and go through a few heat cycles. My initial impressions: Sweet Jesus Mother Mary, this thing shifts !!! I was expecting some performance, but nothing like that Overtaking on the highway is now a breeze, even at 6tg gear. On wet roads @ 3/4 throttle breaks traction in 3rd gear (stock michelin's). I'm laughing like crazy everytime I hit the throttle. Later i discovered that i was in the Map1 (95ron) Slight supercharger whine is noticeable which only adds to the experience Short summary: money very well spent, I'm greatly satisfied. Too soon for me to tell if the overall balance of the car is still maintained. I need to show it some corners for comparison before and after the mod. Many thanks @Matt@Cosworth for the constant support. Also as predicted by reading a few threads here on the forum, a few supported mods are on my list now, mainly brakes update (rotors, pads) and tires + wheels. I'm running now 5W40 engine oil, and with low-temp thermostat it keeps the oil temp at around 90-100 C (195-210F), coolant temps are at around 78-90C (172-194F). Will have to wait until summer and check if the oil cooler is needed. Few pics after the install will come soon. |

[edit] I also wanted to add, be sure to tighten the intake manifold bolts in stages. If it takes 60 ft/lb to tighten fully, tighten them in at least 3 stages. Start by tightening them hand tight. Then, go about 20 ft/lb. Then 40 ft/lb and then 60. You want the manifold to be evenly tightened and completely flush with the block so that the gasket compresses evenly without leaks.

That could work but there must be a page of torque specs.

Hello folks, I started installing the supercharger yesterday and am nearly finished. I was wondering if you all capped those throttle body coolant pipes remaining on the engine or connected them with a hose? I'm having trouble sourcing silicon plug caps and think connecting them with a hose would be better than a cheap rubber vacuum cap from the parts store. I'm referring to the coolant stubs that feed the throttle body, not the stubs on the throttle body.
