Hang on a minute.....he (Nismoid) has come into this thread and made a smart-arse comment. Paul has explained fully what the situation was, even offering the dyno operators number (not our tuner) if he needed it clarified.......THEN he has come again with another smart-arse comment (world leader crap) So Paul has returned serve....and good on him, are we supposed to sit here and cop it. He doen't need to put up with that crap. Here's a copy of the result and the dyno operators number if anybody wishes to call him for further questions. We are just about over this whole SAU thing.

Someone had to take over from the SST brigade, didn't they ?

You are getting offended by your own words. World leader has your trade mark on it. So, can anyone get a world leading build and performance...? Perth was too far to drive but Sydney is much reachable.

Please do not leave SAU.

well my AFR is flat on both Jim's dynos.... and the dyno at the GONG...

maybe it is just a sensor thing, I would hardly imagine the car is actually tuned like that AFR, as it is not consistant with the other information... i.e. the smooth power curve or the other dyno sheets I have seen....

12-12.5 still seems ok to me :rolleyes:

oh and don't stress Stace :rolleyes:

two.06L - let's settle a few things here once and for all... I think I speak on behalf of many people when I say that the 466rwkw power figure seems a little high for turbos that are rated at 640hp, yet your car is claiming to be pushing 624 hp AT THE WHEELS... And apparently you haven't even turned the boost up!!!! Can you find any logic in what I'm saying??

I'll ask you a simple question, do you think there is a difference in dyno figures when conducting a power run in 'shootout' mode and 'non-shotout mode'??? I have done a comparison with my car (see here: http://www.skylinesaustralia.com/forums/in...opic=78364&hl=) and have noticed an increase of around 10%.. So that's why I'm asking if you have a dyno graph in 'non shootout' mode, to make the figure more believable.... My car has 365rwkws, but 396rwkws in shootout mode, does that mean I should preach to the world my car is a 400rwkw monster???

Just have a good think about it...

For anyone thats interested the two Dash 7 GT28R's come up almost line ball with the GT3540R in 1.06 ARR turbine housing form for compressor and turbine flow . The GT28R's (2860R's) have a little more turbine efficiency (75 vs 72%) and flow a little less at lower exhaust gas pressure ratios .

I think HKS GT-SS's use a slightly different comp wheel and the maps would be interesting to compare .

Non-shootout mode can be configurated by the dyno owner/operater, so it would be rare to get a conservative figure in that mode. I don't think Ben @ Racepace has any sort of ego regarding impressing customers with large numbers, and so has his kit set more realistic.

2530's use a T3 comp wheel that peaks @ 35lbs/min, theoretically twins are worth 70lbs/min or similar to a T04R/Z - T66 turbo flow wise.

p.s. my dad can still beat up my mum.

TommyK: Have all your goodies been installed and a final tune performed? If so, do you have a dyno sheet you wouldn't mind posting up? IIRC some of your modifications are very similar so it would make an interesting point of comparison.

dont know bout these 'so called' european performance cars...

FIAT stands for:

Toniii

I never thought my European car was a "performance" car :)

BMW: Brings More Women :O:P

You know, the money-grubbing, self-absorbed and ego-centric kind :D

Lucien - I do believe I posted one up a while ago. Check for posts by me in the NSW section.

Mind you - I am not happy with my CRD tune. The car is laggier than i would have expected with these turbos. I am going in to BEL tomorrow to get a road tune done. Full boost @ 4800 rpm in 4th is comparable to Mik's tune, and he's running GT-RS turbos :D. Not happy!

Will let you know results tomorrow (hopefully)

Sorry, what I meant was: I remember you saying that the cam timing needed to be played with (and, IIRC, there was also some issue with your boost controller). Hence I was wondering if those issues had been corrected and a dyno done.

Seems like all will be answered soon anyway :O

Tommy k,

This is the 1st negative feedback i've heard from crd's tuning...you need to remember that the gtrs turbo application is top end power. gtss is better for mid range.

Just so you know - I have the same turbo setup on my r32 along with the typical mods i.e. pfc, cams etc.

I can honestly say that crd are the most reputable gtr tuners in nsw & possibly aust - my results were amazing :O

Marko.

      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?

      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.
