If i can find a cheap pair of -5 or -7 for now i'll use them and keep the RS's for when i do the 2.9. I just didnt wanna chuck the stockies on and and blow a motor and turbo at the same time.

Funny enough just got off the dyno today after fitting M&W CDI unit.

Anyway, the graph R31Nismoid was referring to was up to:

med_gallery_705_63_26377.jpg

One curve was GT-RS twins, 137mm thick Apexi drag intercooler and Greddy plenum, the other was 2860-5 twins, 100mm HKS cooler and Nismo plenum. I'll let you work out which is which.

The graph below is the same setup, but now on E85 and M&W CDI as fitted today:

PS - I like E85 :D

$2600 new from GCG -10% If your a club member, Inc GST.

Gav, what sort of boost were you shoving down the throat of your engine? There will be another comparison soon between RS's and 5's. :D

Still running 24psi. The ethanol just seems to accept more and more timing. The big fat spark from the CDI helps the tune significantly in the mid range also.

Huge... 40hp? It is a good improvement; you must be easily excitable :)

40rwhp more = 30rwkw more

You don't get that kinda gain dollar for dollar as easily hehe, very excited. You'd feel that driving around for sure, plus the pickup you'd think would be quicker too.

At the graphs... maybe you should look again.

It is a "standard" gain/improvement from switching fuels.

Check the GT-RS to -5 comparison on the top graph, some of the comments are aimed at that and others at the fuel change, tho the comments havent been clear on which they're referring to.

Mike, most are referring to the difference from gt-rs to -5 results on that one graph as MrStabby stated. That one is an impressive difference. The gain from fuel change is quite normal.

Ahhh, noted :)

    • 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?

    • 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/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
