Isnt this turning out a little excessive for sub 400kw?

I wonder why it needs so much flow, le hmm.

Sorry mate

Didn't realize I was spending your money,

Flow is no longer in question Jez have spoken with e85 guys and they believe it's related to the fuel heating up to much second pump is to help with said issue

I think what he meant by excessive was its seems odd that your fuel system isnt coping as well as others have, I dont think he was talking about cost.

Eg some people are getting enough fuel flowing to make around 360kw on e85 using a single 044 intank with standard fuel lines and you are having to add a surge tank, bigger lines and another fuel pump. Granted I dont think they are going to be putting out quite as much power as you when your tune is finished and they werent running as much boost, but still.

Sorry WHAT?

Dont be so defensive like im mocking your hard earnt layout. Good luck to you, I hope your stuff turns out well, I message Jez on the regular and get updates on how your cars coming along. The way you replied to that is almost offensive.

Mitch above is on the money. Im simply curious as to why its needing so much flow, and in a perfect world that could have lead to discussion about what other people have flowed with what setup. Who knows, maybe a few great minds would have joined in and helped troubleshoot so you can find out whats going on.

Spending my money, pff.

:no:

360kw with single pump is the limit.... Well 357 was the final SAFE number anyway

Standard fuel lines were all over and done with above 340ish.... I had to go bigger lines and modify the fuel tank hat...

This I was not aware of

GTR/GT-t = same last time i checked... Wonder how the GTR guys are getting 400rwkw+ through stock lines & E85 (with just a Nismo pump) :unsure:

I think its a lot to do with the fuel hat itself.... It was a restriction.... Hence the modification :)

355rwkw here on pump98 and single pump no restriction. and 335rwkw on eflex no restriction all stock lines and rail. in gtst.

Well i dont want to go dribbling shit without properly understanding it myself BUT on my car the fuel pressure was unsafe at 360kw, after the mods were done and it was rechecked the fuel pressure was spot on at 357kw so it was obviously a restriction...

My original post from page 30 said exactly that.

Then I edited it in fear of a flaming :P Thanks for putting it out there though, I knew I wasn't going mad.

Sydney is warmer than Mexico. We need stuff like 15 litre sumps and 3 fuel pumps. :woot:

Hahaha exactly.

Maybe this will make a few people scratch their heads.

I'm a bit behind on reading all threads at the moment. Too busy, so i tend to miss post replies where I usually see most even pre-edit :P

Nismo outflows a 044. Im hoping my single walbro 400 will be ok otherwise i will mount a 2nd pump in tank

    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
