Very first pull on the dyno, well once i changed to a 7 bar map sensor. I used 16psi springs in my twin scroll manifold. But for some reason 22 is my low boost. Its a major job to get the wastegates off as i have plumbed them in and very little room to work around.

On this run i backed off at 6400rpm

Overlay shows my previous best with -7 copy twins.

Both on E72, both have same tyres etc etc. the e72 in the tank atm is 6 months old

How about some rpm scale love there Jez instead of road speed?

All looks promising so far - I bet you're happy!

I can try for u stevo but its only roller speed and i can input what rpm at a certain Speed if that makes sense. I mainly use it as a reference. Worst part is it doesnt save each time the dyno is on so i cant do comparo's on different days with rpm.

Gotta be happy with that jez

Very. Cant wait to push some timing into it. Think i might stop at 420ish kw. As stock engine and cams

Yeah that makes sense, fair enough.

When's more tuning going to happen?

Putting fresh fuel in for that?

Would be great for someone to do back to back testing on a range of these things. Eg 5557, 6262, 6466 etc all on the same engine, same dyno

I think I put a link in here a while back from some guys who did just that, albeit on a 3.4L jz

What twin scroll manifold and gate/s are you using for the precision Jez?

6 boost manifold twin tial 38mm gates. Custom dump and plumb back piping.

Stevo hoping to get the rest tuned on e70 sunday. See what boost i need for 420kw. Then wsid for a 1/4 mile run to see if she holds together

    • 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.
