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....

Stace or Paul i can see you guys reading this thread we shlould all organise a BIG Dyno day CRD or DART at the end of the year and see what everyones cars are puting out.

It would be good getting 20 or so GTR's all with different set up and some the same just see what the mods make.

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??

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      By GTSBoy · Posted

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
