seems pretty laggy, but I guess it doesnt really matter for a circuit only car

really? I wouldn't call it laggy. it reaches 260kw at 5,500rpm and holds it to redline. that's a pretty nice bit of power for a little 2L.

It's coming on hard from 4,500 onwards and is very strong by 5,000. so as long as you can keep it above 4,500rpm it will be hauling ass!

Well after Targa I think it's time to get a gated sump after i ran a bearing the night before the event. I'm also going to rethink the breather setup to stop it blowing oil out of the breathers all the time, and last of all put some cam gears on to improve response.

I gained some motivation today, put the dead engine on the engine stand, and drained the oil out. There more than an acceptible amount of bearing on my magnetec sump plug. But I ran out of motivation when it got time to remove the sump.

Nice vids...seems E85 is the way to go :)

I call 1bar @ more than 5000rpm laggy, but thats just me :)

and yeah doesnt make a difference on the circuit as long as its kept over that sweet spot!

Cant have everything in this world, and you dont make 260+rwkws from an RB20 unless you move the power band up over 4,5000rpm!

You so can have everything... You just need to shoe horn a V8 in with twin turbos... :D

So what were you doing the night before the event to spin a bearing and call oil surge issues?

Was at Baskerville raceway. I've now been over the datalogs, and the oil pressure keeps dropping to 0psi under brakes (didn't for targa though)

The lag wouldn't have been a problem if I was able to rev to 8000rpm, but the new engine had issues to prevent that, so I lost 1000rpm off the powerband.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
