Had my r32 gtst tuned by Sam aka Dr Drift yesterday and i cannot reccomend him enough. He really gets nothing less than the best from your car. I think we were on the dyno for close to 3 hours and he charged me for a bit less, so i was really happy. Not like other places that want to sting you for the last 5 cents they can.

Anwyays im sure most of you know his work is 10/10, here are the results.

This was achieved on stock injectors so it shoudl also silence a few critics.

When you look at the dyno graph you can see what i went in with and what i left with. What you cant see is the afr's that were all over the place with the chip i drove in with and how perfect they are with the chip i left with.

Made my day :)

looks good. Sam knows what he's doing :)

did you get that done up in brisbane?

what turbo have you got? Rb20 i presume?

Cheers.

Sorry, relevant mods to the RB20 are hks 2530, nismo adj reg, bosch 044 intank. Top quality intake and exaust systems help too. I think the stockers limit is around 160-170 but i could be wrong.

Anyone who gets the chance i highly recommend, i would truly be disappointed if i couldnt have him tune it again in the future. Possibly for some tomei poncams (stuff adj cam gears) and nismo 550 or 600cc injectors.

I also have fuel economy now !!!!

EDIT: yes this was done in brisbane, gold coast actually and was @ 17 psi

thats good power for a 2530!

and yeah, getting good fuel economy was one of the highlights :)

what are the air/fuel ratios like now, around 12:1? put up the graph if you can.

Yeah the air fuel ratios where as sweet as could be, around 12:1

I dont have any graphs with afrs on them, i was watching them on the screen though as he did run after run, tweak after tweak :)

How is your fuel economy now

how many litres per 100 km?

cheers

I dont drive it sedately enough to tell you sorry, plus i only got it done yesterday. If i could manage to drive it without flogging it then that might help. Its also my toy car so i only drive it a 5 or so times a week.

All i can say is its much better between 25 and 50% better at a reasonable guess.

Not really (not that im a critic)

But you've obviously bumped the rail pressure

nismo adj reg

So its kinda hard to tell :P

If you hadnt bump'd the pressure then i'd pay a silence of the galleries :(

Oh... and Sam was getting Emulation last tiem i spoke to him (couple months)

So i'd say one burn @ the end and she's away

He emulates them for sure, very tidy equipment he has been developing for years now.

And yeah Nismoid the pressure is bumped up, it was really only significant because sam had never tuned that from stock injectors.I plan to get the injectors and cams before he is back next. That should enable me to find the limit of the 2350.

i've got a similar setup (2530/RB20) and i'm not making as much power but mine seems to come on boost full boost (18psi) about 400-500rpm earlier from what i can see on your graph.

Damn, that sucks, i really dont find it laggy at all though very compareable to the stocker. I have a Profec b spec 2 that opens the holds the wastegate shut untill it reaches .75 bar.

I dont think you can tell how laggy something really is on the dyno

My 2 cents :(

You'll find that most operators don't really start loading up the car below 3k so it doesn't give your turbo the opportunity to start building boost as it would on the street. On the dyno i hit 20psi by 4k, on the street it's more like 3200.

but think about what u just said, it that really giving u a good tune??

your gonna be tuning it for lower load points on the dyno then it hits the road and its using higher load point which wasnt tuned as well.

u got a dyno to simulate the road conditions and u dont use it to the full potential, i think thats abit silly.

thats my 2 cents, no disrespect to anyone.

Glad to hear your happy with the tune, I was :)

yogi - Most of the low to midrange has been re-done, some runs were loaded up down low, Mick's car has excellent transition from the 14.7 AFM when running on the factory O2 down to 12.0 as the car's generating boost.

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Best place to order Authetic R32 Parts in Japan

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)

      Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...

      Blue slip

      By MBS206 · Posted

      I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...

      Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
