I was definitely reeling the other cars in but they had me by 3 car lengths out of the hole.

Just tossing up between the .82 and the .63 rear housings as every other way around the problem involves making the car less drivable on the street. (other than going 3.5L :whistling: ) I really don't want to go to a 4k stall converter.

You might get away with a 0.63 using pineapple juice. It would be waaay more lively and it seems that you have maxed out the compressor anyway.

Even if you drop a few kw at the top end it would be a much faster car all around.

I ended up with a 13.9 but was going 141.3kph by 1/8th mile after the 2.8 second 60 foot. Only one timeslip as the tards lost the first one somehow. Thats .4sec worse than the last run, back on the highflow with 250kw, speed cut and throttle restriction. Power doesn't make it quicker unless you can launch it unfortunately.

First run was only a couple of hundredths quicker IIRC.

.82 would be perfect IMO

Whilst I agree with Wolverine, I reckon the .63 would make it a bit too much on the road.

It's a very, very well behaved (and quick) road car as is, it'd be a shame to see those manners disappear in the name of a good 1/4 mile time.

I am getting prices as we speak, Tial housings are bloody expensive but I only need the housing, not the clamps. Price with clamps is $670 delivered. >_<

There are Tial knockoff .82 rears on ebay for $289 delivered, perhaps I should get another one of them seeing as I modified the one I already bought. The quality is great.

The safe option is the 0.82 but I think you could get away with a 0.63 and not find it a choke point with that compressor using E85.

At that price for the Tial knockoffs it is a shame you don't have an easy peasy high mount manifold with V-bands so you could swap the housings quickly.

I cut it up to modify it but I need another turbo to jig it up, then the exhaust/wastegate would have to be redone. I just want to bolt a rear on this kit for now so I will have to buy another.

If I could take off at good boost he wouldn't have had a chance. Next time... :P

I was down at Edge tuning again today after sorting out the boost control circuit and fitting the lower temp thermostat. It was also a good chance to change fuels to United e90 as there is one local now but the extra torque put an end to any fun I was expecting.

3rd gear runs saw the torque converter lockup clutch slipping badly, that and we couldn't work out how to get rid the speed cut with the Fcon for 4th to be very useful. It looks like I will have to upgrade the stall converter again and refit the SLD.

As it was, with 4th gear runs to around 5k it was comfortably hitting 300kw at 25psi (flat finally) If I can get the SLD re-installed I may be able to sneak a tune in this weekend. :whistling:

I'm bloody amazed, as is Cihan that this little 2.5 just keeps taking more...

Considering the torque output Cihan feels it is doing very well. Not that many engines would be taking the abuse this one has, its done literally 300 dyno power runs and lasted 3 years powered up with over 3 bar of boost at times. I'm quite impressed.

I don't have a choice smashing limiter, it happens all the time due to the stupid auto failing to shift in time. At least pinking is a thing of the past...

Still running the 1.06 Tial mate, looking to crack 350kw this time so I will need it.

Its a Dominator custom stall converter, it flares to around 3k when stopped but flares to 4k once boost kicks in (as the revs they stall to is largely torque dependent) The issue is the lockup clutch is too small though, not the stator itself as its a 5 axis billet unit and should be bullet proof.

Not sure yet if I should get another converter made or just cut this one up and get more clutch plates fitted...

    • 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.
