+1 for the tough book! In the last 6 years, I've drowned it twice, dropped it in the bilge (i work on superyachts) a dozen times, tuned a 3000hp 4000 series MTU marine diesel with 47psi of boost, seen 16 yachts, it's been to 18 countries, 4 continants, saved my ass in 3 air ports, had me questioned once in germany(thought I looked suss with all the datalogging/satalite gear and a millitary toughbook), had 3 different OS's, 2 ram upgrades and downloaded over 300gig or prn...

oh and tuned my GTR... ha ha ha must have flown off the seat 25 times!

without a hicup!!!

who needs a sissy mac!!!

Hey Trent, how do the trust sumps stack up in your sump testing?

Cheers

Its the only one i wont be testing as i know a few guys running them with no issues, the main reason though is in a s13 chassis it will hang too low as ive lowered the engine 25-35mm it will scrap ants off the pavement.

yeah the trust sump is a proven winner if you are staying wet sump and in a 4wd GTR. they are not expensive to buy, just need a competent welder and you're done. they are the right design and are about as far as you can go without it being too low (some would argue it already is a bit low but it has to be).

i had the trust sump in my previous gtr...i always paranoid when there were undulations/pot holes in the road, i used to hold my breath if i couldnt dodge it in time - it hangs way too low for my liking for the street

the rips sump (which i have now) on the other hand is much better in that it does not sit any lower than stock, in fact when i look under the car the cross member is about 10mm lower than the sump

id drop the restrictors down in size, i tested the rear drain on our engine on the dyno and found it did NOTHING useful... so we dont bother with them.

We drop to 0.95 in the drift 26's and have no issues, the 25's need more like 1.2mm or your lifters start to starve.

my engine is running 1mm restrictors in the middle and rear and a bundy tube feed for the VCT from the oil pressure sensor (RB30) and i haven't noticed any lifter noise apart from just after initial startup before oil pressure has risen to operating pressure

      High temp brake fluid?

      By PranK · Posted

      The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.

      I've always approached this as, price is comparable between low temp and high temp fluid. Just put in the high temp fluid. I've not going to lose any sleep thinking about could I have saved $20 on brake fluid that is going to live in the car over the next 2 to 3 years.

      Nah, the creases were pretty large, and the sheet metal is pretty thin and hard to work out, time alone is in the hours to fix, and would probably have more bog than I would be happy with In other, more happy news, I gave MX5 Mania a call and they have a few clean boots available for $400 a peice, I've contacted Fineline and given them their contact details, I'm a idiot for not thinking of them sooner

      High temp brake fluid?

      By GTSBoy · Posted

      That really depends on how hot the brakes get and how much of any heat is transferred into the fluid. That really makes it at least a vehicle specific question, and more than like a specific vehicle specific question, depending on what brakes (ie stock, bigger rotors, different calipers) or even what pads are on it. And then there's the question of cooling air. Is there plenty stock? Is there no special cooling arrangements stock? Has some/more been added? In other words, I think you have to do the experiment to obtain the data. And if you;re worried - tie on some ducting?

      High temp brake fluid?

      By PranK · Posted

      In all the track days I've done over the past few months I've only had 1 issue with braking and thats with my current EBC pads (can't remember the colour, but they're not a track pad). I don't *think* I have had issues with brake fluid getting too hot, my understanding is that when that happens you will have quite noticeable brake loss - which I haven't had.  I'm using just regular ol' Penrite Super DOT4 fluid. I use this fluid in everything and my cars always seem to stop so I see no reason to change, except ... for the 335i. I need to do a fluid flush and was thinking about my fluid of choice and wondering if I should consider using something more high temp? Its not a super fast car by any standards but I'd hate to do a flush and then find myself with no brakes when I get. to Wakefield.  I guess, my question can be summed up as "How fast do you need to be driving to need higher temp brake fluid?"  I remember high temp fluid was considered a must have back in the day when I had my GTR.
