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

ben , my mate left croydon with around 12:1 and ended up at sas with 12.7:1.

to be honest he hasnt had a problem . we actually rang jim at dart late yesterday afternoon about this . he said he has built quite a few 400 + kw gtr engines that have been aggressively tuned by croydon and refuse to give up . he believes it all comes down to how sensible the driver is . he told us he has built around 85 gtr engines in the last 5 years and many of the ones that came in blown up were only making around 250kw with 11.5 :1 mixtures , but were driven as if they were stolen . we're looking forward to visiting dart and meeting jim.

on the CRD graph the AFR is 12.4:1?

Richard, no its not... its sitting 1 division below the 12.5 that is 12, and it bounces along there on the line or 1 pixel above....

Yep, that is what Jim told me also.... he certainly can build a beautiful RB26 that is for sure! I get knocks of 12 most drives, and on the dyno it saw 17-20 at full tilt...

I can't wait till blitz and Marko have run their engines in, as they are or have recently had a DART built motor....

hahaha you were reading my mind!!! I saw you reading the posts, and wrote the above prior to your message.....

Jim @ DART is a great guy, I am certain you could do a power run for only a few $$$$ as a side note he mentioned to me that he was looking at charging $150 per hour dyno time, and that was for just anyone off the street....

I am sure if you mention my car, and SAU he will come to a nice number for you :)

it is well worth the chat with him regardless....

Your not scared of a few little gtst's running on the dyno aswell are you ;) ? be easier to get the numbers for a dyno day if you let them in, I'm sure they don't mind it not being fair you being RB26 and all

The GTRs regularly taken to the track to be thrashed - how do they get tuned? Do you have to specify it'll be a track warrior then get a lower peak KW?

I'm confused I thought that unless the car was pure dyno queen it'd be tuned to give and take punishment??

      R32 Gtst - Track Car

      By bcozican · Posted

      Thanks mate   It's all coming together finally. It's just a better racecar now and also yeop I've pulled my thumb out and committed and the combo seems to be gelling Depends what you mean by not much more haha There's at least a 1.19 in this My fastest lap posted lost 3.5 tenths in T10 and this was on 80% power and 5 heat cycle old tyres The next session/ lap we did we were up 4 tenths with the car out of the final turn T12 accelerate straight and going with 1 or 2 tenths to come from the power to the finish line and the shifter/gbox combo stopped selecting    So we wouldve had it. The whole thing..   Also repeated this the very next lap up 3 tenths out of T10 and same issue Add some news tyres and we good   Looking forward to a break then yeop WTAC and see if we can actually have a decent run

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action

      Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand.
