This is the internet...a quick "google" of performance ceramic coatings will give you hundreds of examples of where this product has been tested and proven. Like i said before, your example does not mean or prove anything if no before/after comparison is done (this is how i do my testing). Like Silv.is trying to explain and i have also stated earlier in this thread, the coating is done on the turbine side to aid gas flow....not too keep things cool around it, thats the job of heat shields etc.

Thanks for the acknowledgement of our work...its good to see the time, effort and dollars paying off

The coating claims to work by keeping the surface of the pipework cool, ie keeping the heat within the piping. (actually the second site simply claims it is a 'thermal barrier')

If you acknowledge it has little effect on the amount of heat radiated from the pipe/exh housing (in contradiction to how it is 'meant' to work) then what do you think it actually does? I am not arguing that keeping heat within the exhaust improves performance, thats a given, im just trying to determine what you think it does. As i've said, if the coating does not decrease the surface temperature of the coated item then it is not effective. (The image I attached shows the surface temp is high in the coated region and at the same time clearly radiating a significant amount of heat as the subsequent uncoated region is comparatively extremely cool- it shows the thermal gradient is not affected by the coating.)

Actually I have googled (and had a quick look on a few engineering databases) and havent found any technical information in support of the coatings, but alot to the contrary actually.

Are you not able to understand the written word??

Go back and "properly" read this thread....i think ive made myself clear in no uncertain terms what i think it does, the performance benefits of it and the application ive used it for.

As for contradiction (seems to be your favorite word) go back and read your last post...you make no sense and are starting to get lost in your own babble.

As i said previous...I think you need to start you own thread...you seem very passionate about it

Not passionate, just bored.

I've read the thread and your comments, the word 'contradiction' comes up in my posts alot as that is what people are doing when talking about these coatings. I thought my posts were quite clear?

I will leave this here, if you wish to discuss further we can take it to PM rather than draggin your thread off-topic

All the best in your chase for 9's

Hard luck paul & stace. Now just have to wait and see how they perform on the strip.

I'd be looking forward to hear your impressions of the gtrs's, their spool repsonse mainly.

It'll be about 6 months beofre i'll be able to fire up the R, but then we'll have some stats of how the gtrs's run with a 3ltr bottom end

All the best for tomorrow!

No hard luck...just a little surprised at the lack of improvement.....but.....this is only what the dyno says.

The real improvement we want to see most is trackside.

Stay tuned....tomorrow the real test begins.

Hello stranger, are you racing, heres something for you boys to think about. 1.3 sixty footers, bring it on.

At least say "courtesy of tommo" when using MY photo

I'll be there tomorrow taking photos as well

Yeah...pretty rude eh TommO...not only does he use unauthorised material....but....its not even a picture of him at the wheel....lol

Make sure you come and say g'day mate.

[LTSJayce]

And the big day has come...and I'm stuck in freezing cold Can'tberra waiting to know how my fave' silver 32 is travelling at WSID. Any news?!?

[rb26s13]

come on i want results

[TommO]

Seemed to have constant issues through the day, mechanically and launching issues. Was good to see it out again though, better luck next time

[rb26s13]

so wat'd it run :

[Amaru]

The only time I saw it run was in the afternoon, and it didnt look overly happy and was towed back... rumor has it a newish N1 oil pump took its bat and ball and went home?

Good to finally see some GTR's out though, I was in the cheer squad for JUN... not bad for its first run, and the thing sounds mean

[rb26s13]

eek not a good day at all poor bugger oh well hopefully after the problems fixed it'll be back out and fighting strong

I am dissapointed, as I know you are. But I am not really all that surprised. I truly believe that you had the ideal engine configuration for 2530's. The dyno and track results certainly confirm that.

On the other hand, the results I have seen from GTRS's are patchy, sometimes they work and sometimes they don't. The only consistent good news seems to come from engines with capacities more than 2.6 litres.

Maybe the alternative (from a 2.6 litre) is higher RPM, but that is hell on components.

Good luck, I sure hope you get those GTRS's to work for you.

cheers

Bigger cams needed apply within!

[Sydneykid]

Bigger cams needed apply within!

Yep, then bigger valve springs, lighter retainers, more durable valves, higher valve train wear and stronger rods needed (if I remember rightly). Then maybe lower diff ratio, higher rpm launch, drive train wear etc etc. Higher and higher rpm is a vicious spiral, the secret is to know when to get off.

cheers

Yeah SK your dead right mate. The 2530/cams/displacement setup was perfect......tried to launch the car the same as the 2530's and bogged badly off the line. Back at the pits we decided that a 9000rpm off the limiter launch (previously was only 8250) was needed and bang oil pump drive collar is now in two pieces.

Ouch, I read that in the Compact thread. Engine damage?

cheers

[aus spec 32]

That’s bad news, I was hoping you would get more power and run 9s. I’ve got the same motor set up and gtrs turbo’s and all the extra surge and lag is for nothing.

Unknown yet, but we run an autometer warning light and a 30psi hobbs switch to monitor pressure. It was an immediate shutdown, but as you know these things are hard to catch. This engine is over 2 and a half years old and was starting to breathe a little heavy and make "interesting" noises on the dyno in the last 6 months, so it was planned to strip it and freshen it up soon.

Tossing up either using a JUN pump or going external single stage dry sump pump scavenging from rear of sump feeding the oil filter at the relocator block...what do ya think??
