Cam Gear & Dyno Tuning Results @ Croydon Racing Development

[Marko R1]

I am extremely happy, it drives like a standard GTR @ 60kmh in 5th gear (1300rpm)

2nd gear breaks traction at all 4’s on shear acceleration J

Please refer to attached graph, this is my 4 wheel dyno tune figure by CRD on the 20th June (my birthday)…

THE CAM GEAR DEBACLE…now proven!

I was there from start to finish & saw the comparable difference.

The red line (on the graph) is tuned with cam gears at 0 degrees

The blue line (on the graph) is with tuned cam gears - keep in mind I do have the poncams…what a difference!

Jim has made an additional 100Nm without sacrificing top end delivery…

This proves that adjustable cam gears do make the difference & that Jims dyno tune has made a massive difference in torque!

Only the experienced guru’s of the industry are aware of this advantage.

I also had a long discussion about road tuning with Jim – he is of the opinion that you cannot simulate ‘load tuning’

i.e. load tuning at various rpm’s for a specified time period, where can you do this on the road & how can you road tune a car under load?

At the end of the day Jim has 15 years experience with GTR tuning & the experience alone is working with all facets such as drag, targa, circuit, national teams, race production class etc….who else in Australia works alongside with top tuners in Japan & national racing teams? I guess this is why he is the busiest workshop in Australia, just have a look at the number of performance cars he has in his workshop & yard (over 30 cars).

YOU PAY FOR WHAT YOU GET – yes other tuners are cheaper but you will not reach the maximum potential if cam gears are not adjusted to suit the setup.

The way I see it, if you are prepared to spend over 10k on an engine then investing another $400 additional for a proper tune is the way to go…

Question: would you pay the small difference in tuning for an extra 100Nm of torque?

I am not here to convince you or sell CRD but I did want to share my experience with you as I am extremely happy with the outcome.

Thank you Jim

Big wraps!

What was the boost level and AFRs?

Standard bottom end I assume

[Blitz]

Marko, excellent results.

Tell me though, after the tune how is the cars response on the street with the GT-RS's

Good work

I'm happy that you're happy with your car.

But I use the white colour scheme and so I couldn't read your writing without highlighting it

Sounds like a beast of a car.

[7heavn]

Nice power level .

Now out to WSID to see what it can really do .

[Abo Bob]

What's all that wobbling about up top?

Can you feel it?

[Morgs]

I think thats the AWD on the dyno correct me if im wrong

[Mik]

Looks good Marko.

What size tyres are you running? (or so you have a plot with RPM on the independant axis?)

And what boost and AFRs?

[Guest two.06l]

our did that too....until we threw the AVC-R out and installed a BLITZ

Paul...but did it do it on the road? A friend's WRX used to do the same with the AVCR on the dyno...but on the road, it was fine.

[Beer Baron]

yeah, I was curious about that too. my guess is boost controll. certainly a very nice number. Very sharp curve. BIG fat top end, but the bottom end seems a little dissapointing to me. I would personally like more 'area under the cruve', but i don't think that's a reflection on CRD more a turbo choice thing. Do you have a graph with Y axis in RPM instead of speed? if so could you post it up?

enjoy mate

Agreed, but you'd be a miracle worker to get Jim to tune a GTR for $400.

$500 is what he normally charges just to dial-in cam gears, let alone TUNE the GTR.

A basic GTR tune starts at $800 and rapidly increases from there.

I have never stepped foot in that workshop without being slapped with a bill LESS than $1000.

[blk180]

Yer great power on stock bottom end. i think he sayn for 400 dollars more the another tuner.

I spoke to them today they said $350-750 for a full tune who knows but..

Doing a power run on Saterday morning to see what this biatch is making :Pimp2:

[renis]

Merli,

Im with blk180....he is saying that it is only an additional $400 or so in comparison to most tuners who charge anywhere b/w 500-700 etc...

Im in agreeance with you marko....fantatsic results...wow pretty impressive!!! Im amazed at the difference with the cam adjustment...thats worth the extra $$ to me!!

I'll bet you $50 that he wants to change the oil, and spark plugs before tuning it.

And it seems the more power a GTR makes, the more he charges... Presumably because there's more liability and less room for error with highly-strung GTR engines.

Understandable I guess, but it gets old when you're told "$350-750" and then get slapped in the face with a $1500 bill.

Anyway, good luck, and you have to come to the next dinner and let me take it for a spin... I'm having major power withdrawls

P.S. Have you put on an oil cooler yet? :squint:

Ahhh gotcha... Fair enuff.

I'll come to this months dinner..

I was going to get an Oil cooler but after 4 new so3's + rego i have no bling bling left

There was a fair amount of meat left on those tyres?!?!

[Blitz]

I was just thinking the same thing - though the car looked pretty low the last time I saw it
