Yes they are using 1000cc's and also making more power...

What has that got to do with the 800cc question and what power they are going to be safe at? You are suggesting 800cc injectors are going to be safe at 400rwkw and not 300rwkw as I have said? At least, that's the way your post reads - maybe I'm reading it incorrectly.

Keeping in mind that we've had this discussion before about telling people 'she'll be right mate' is not optimum advice for a public forum and considering that AFRs will be extremely lean to achieve that hp. You can certainly make more than 400hp at the wheels on 800cc injectors but take the car out and hold 3rd, 4th and 5th til redline and see what happens.

But....I suppose this guy can go out and run his car on the limit based on your advice, blow it up and you will be able to wipe your hands of it. I feel a little more responsible for the advise I give here so it's fairly important that the whole picture is examined.

Isn't it basic maths ?

620rwhp on 1000cc's

=496rwhp(372rwkw) on 800cc's

Yes it is basic math if the figures are correct to begin with

It is, but some seem to struggle...

Yes they do.

Can we get a non-perth car to gives accurate hp figures in here. Is it just me or do you guys seem to all make 100hp more than you should?

Maybe it's the air?

Let's see the highest injector ms in the tune for both those cars at peak power and the AFR's for both as well please.

These are from NSW, seems to be similar results.

380kw vq30 with id1000's at 80% e85

I maxed my 900cc injectors@65psi fuel pressure out at 420kw/560hp. s

Maybe there is something wrong with the Qld air, too much humidity ?

100hp more than they should... So my car should make 380rwhp? 132.5mph trap speed is pretty good for that power hey :worship:

Maybe not everybody tunes at 10:1.

Was waiting for you to jump in. Had nothing previously?

Still waiting for those figures. You gonna sit there and keyboard slash or you going to do what I asked 6 months ago when you pulled the same gutless shit?

LOL thought so. Every time you have a dig at me on the forums I ask you to provide proof in the tune and you only ever come back with your ET and MPH. Never hard facts.

Every time I give you what you ask for you ask for something else...

Funnily enough I don't store photos of others timeslips, injectors duty cycles, dyno graphs etc just to give you some "proof" and I'm sure if I did it still wouldn't be enough.

But what everyone else seems to realise is that I have no reason to lie, after all I don't earn any money from selling big fuel systems when they are not needed :thumbsup:

Pot kettle black?

What you said initially is still totally ambiguous - either you had a flow gauge that measures 9l/min or your worked out the fuel usage from a duty cycle number. You made it obvious that you didn't have a flow gauge and then you went onto say that you couldn't recall the duty cycle number!

And as for injectors I've made over 400rwkw on 660cc sd injectors @ 4bar fuel pressure on multiple cars - but that's because the bsfc of an xr6t is much higher than that of most rb engines; hence why I wouldn't recommend that size injector in this thread.

I'd be happy for you to post the response you gave me here. Tell everyone here what is it exactly that you said when I asked the same information of you when you called me out in another thread? Good luck finding anything because you never responded. Even when I then called you out on it in your own build thread after having aonther dig at me, you still failed to provide the simple data which I asked for.

You have not personally built the cars that are making the hp or running the fuel systems or seeing what happens to cars with inadequate fueling. You just read stuff on a forum and spit it out like its gospel. Apart from your own car, do you actually have any real world experience or is it just you pulling your dick over dyno figures again? I asked for simple figures from you. YOU NEVER PROVIDED THEM. I told you before and I'll tell you once more, if you cannot provide the simple data I have asked for, then your claims of hp are guesses at best.

Nothing I said was ambiguous. You are the one baiting me instead of actually reading what I wrote. Here it is in black and white for you so listen up because I don't want to have to say it one more time.

I DO NOT TUNE CARS. I BUILD CARS.

My tuner said to me 'it's a good thing we have the fuel flow of that pump as it's currently using just over 9L/min of fuel'

This is based on ms open time of the injectors at peak power. The injector is being told to inject an EXACT amount of fuel. The size of the injector is predetermined so we can calculate (using AFR's also) the EXACT amount of fuel being used at peak power. I was told 'just over 9L/min' I also said in my initial post (without reading back to find exact words) 'I can find out the figures and get back to you guys if it will help you out'

Read it again if you have to. I clearly stated that I would be able to find out the exact amounts if I was required to. I was only told just over 9L/min not an EXACT amount, and I don't have the car here any more to be able to look in the Motec to find out what ms the injectors are open at peak power AND my tuner is away until Monday. SO, does this answer ALL of your questions regarding this topic or are you going to sit there and tell me now that fuel flow cannot be calculated using this method? Coz I'd really love to hear that story.

Oh and completely pointless I might add. You have a go at me in a smartass manner to what effect? Just to puff your chest in a public forum? I was merely stating my experience with a recent build and a few other recent builds and our findings considering E85 is fairly new to most of us in the semi professional scene. Me having a flow gauge that reads 9L/min has absolutely nothing to do with the topic and is only a chance for you to pull some shit for a laugh.

And as for injectors I've made over 400rwkw on 660cc sd injectors @ 4bar fuel pressure on multiple cars - but that's because the bsfc of an xr6t is much higher than that of most rb engines; hence why I wouldn't recommend that size injector in this thread.

We are aware of that, each engine will be different, but if you have some specific knowledge or some way to apply a formula then instead of having digs at me, maybe offer a knowledgeable hand to others who don't understand what it all means and how it applies to them. Hmm?

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
