Hey Dave,

yeah I am sure CRD's is a happy dyno! I'm only able to compare like for like.... many other guys on this forum have been to CRD and got with similar setups 285-315 AWKW so Im in there somewhere....

I did the DART dynolog because :-

A) Jim @ DART offered and is a great guy!

B) very accurate NM torque reading

C) unbiased back to back testing with a known base.....

to gain 65 AWKW and 122NM with slightly less boost is great news from a dynolog....

I also know of a GTR with GTRS making 280AWKW on dynolog making 385 AWKW on DynoDynamics....

Mik DART's dynolog dyno and Jason from the GONG's dyno read with the same initial tune 1 AWKW difference... so I was very happy that the dynolog system is repeatable...

GTRmadness...

the cams made well over 10AWKW with the rest of the timing adjusted accordingly...

I have the sheet with cam timing 0 0 below....

it is also a well known fact that dynolog dynos read quite a bit lower than dynodynamics.... (CRD type)

of note this morning the tyres were cold, and the ambient was same as before.... (205 run)

Jim @ CRD said the tyres alone will sap 10-20 when they get too hot....

interesting!

another thing you might find interesting was that the car was showing a leaner mixture on the sas dyno as compared to crd . we then borrowed a motec lamda meter and confirmed it was leaner . interesting to see what afr reading you got from darts dyno as compared to crd .

When I get back to Adelaide, I will also look to have an autronic or MoTeC wide-band O2 sniffer borrowed for a drive around....and confirm it all

As long as I keep the correct fuel up to the engine (BP ultimate) and not run for extended periods with the high setting of 1.4 I should have no issues at all...

I doubt the car is too lean as it was certainly doing the nice fuel cloud out the back on the dyno!!! ala a stone brother's V8 style...

also I note Jim said I should add a little octane boost (nulon) for any future track days... half a bottle for a tank :D

just for safety...

Kabab.... you will love cams, no question! I also beleive that there is a bit in the TRUST dumps, as not many have these, and maybe more to come as I have been told my exhaust is rather restrictive ( has been chopped and changed prior to me owning the car and has some bad welds and bends.... also 3" )

We should go out for a little "comparison" sessions....

270 AWKW 707NM @ 1.36 BAR

Ever so interesting Ben, thanks for taking the time to post it up.

:wacko: cheers :(

PS; I seem to remember predicting 280 rwkw at 1.4 bar when we chatted last Saturday. ;)

Yes as always SK you played a huge part in the overall development of this car, whilst not getting your hands dirty, it was generally your ideas placed into practice ;)

yeah so 270 AWKW on dynolog and 313 AWKW on dynodynamics is sweet...

but Im more for the torque! 707NM !!!! oh my....

Gary we need to have a chat about AFR's I feel there could be a whole thread just on this as it is such an important thing....

Id love to know what say a V8 team runs for lets say bathurst versus a sprint round...

or for that matter what Gibo's car ran for the 1000....

12 seems to be the number used a lot, but Jim said higher is still well safe with nice fuel....

Good on you mate for testing it out back at the original place and getting that baseline. Between all of them I think should be enough demonstration to people that they really do have to be compared directly.

Sounds like an animal car good on you.

Ben , i had a close friend dyno his power fc at croydon and finished with 280kw . he drove straight around the corner to silverwater autos new dyno dynamics awd and it the same car made 258kw over 3 runs , all within 2 kw. not bagging crd , but i dont believe dynolog reads ( much less ) . crd"s dyno has been proven to be happier than other dd"s or jim must be bumping it up for a good result , then detuning slightly so you can drive away safely.

Ive noticed quite a few guys like you ben , have engines built by jim at dart and tuning by jim at croydon. these two shops must obviously have a good working relationship which is rare . its good to be able to use both guys , get 2nd opinions , all without causing friction .

Correct.... DART Jim previously worked at CRD, and now has set up a very very nice workshop in punchbowl, and turns out some of the most professional work I have seen....also of note is that their new dyno room is state of the art! and has the latest tech dynolog dyno....

Jim @ CRD could most likely tune a GT-R drunk and no sleep.... I'm hard to impress at the best of times, and considering the car was mad fast previously, he made a hell of a gain! EVERYWHERE!!!!

Also of note is that most of the on going work was completed by BEL and I would say 90% of the car belongs to the hard work of Eric there!!!!

so yes, a combo of resources from the best avaliable, and funnily enough, the only bad blood between the workshops is in the customer rivals.... not the workshops themselves.

As I know all 3 personally vouch for each other, and have seen them each be recommended by the next...

happy days......

What AFR's did your mate get and the difference? mine are a safe 12 - 12.1

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Appreciate the feedback. It is street car, but not a daily. Last week I got a quote from a good exhaust shop for a decat, one which is bolt-on, bolt-off to be easily replaceable. I got quoted for around €150. I usually do push the motor, but I wasn't in this case to make sure that no damage is done until I get the cat sorted. I think it's best to also ask the exhaust shop for the other option and see what they can do. If (big if) I were to decat though, would it be best to tune the car or would the stock ECU handle it? As far as I know, the stock ECU is not tunable and that would require additional purchases.

      As above, definitely bash it or get it replaced with a high flow unit.

      Duncan's V37.......race car?

      By Duncan · Posted

      Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.
