Hey guys just got some new turbos fitted to my car and i thought id post the dyno graph up to see what u guys think. Running sort of a light tune to keep my engine alive during track days until i can afford to get a rebuild done :P . Its using a djetro pfc and still on a cat back. Plan to get a turbo back soon to try and get it to be more responsive. Any comments welcome. Cheers :D

what injectors you running?

Im running nismo 600cc ones.

3lit3 32, from what i know i should be able to easily get 500+ hp atw but i dunno about 700 heh. Yea I know im not even close to pushing the turbos but as i said, im trying to take it on the safe side for now as i do some track work. Once i get a full engine rebuild ill go all out >_< . The dyno run was on 2 wheels.

Cheers

Nice, what boost are you running? Looks around 20psi?

seems quite laggy to me. 1 bar at around 4500rpm. nice power though, but they must be fairly large low mouts as the resposnse does not look that great.

yeahh from what i know, the -5 model is slightly bigger than the -7 model, which (i think) is comparable to hks 2530s. Yeah it is rather laggy but im still running a catback so im hoping the graph shifts to the left a bit once ive got front pipes/dump pipes in.

yeah West im running slightly under 20 psi. Btw how do you know its in 5th gear? :P They are bigger than both the gt-ss and the N1s

Cheers

I was only guessing :bunny: mate.

Damn, those things are bigger than Gt-ss, mad fun their. May i ask what condition is your engine in? Did you do a low boost run? Say around 14psi?

west mate, it would not be in 5th gear. most DD dynos are rated to 200km/h only. It would be either 3rd or most likely 4th gear. Even if it was in 5th (which i can promise it wasn't) it shouldn't make much difference at all. if anything it may build a little earlier as the engine is under more load.

Thank you very much, i dont know much about Dyno thing.

Mind if i ask who or which work shop that did the tune?

Are you still running standard injectors? If so whats the percentage shown at 300kw?

D-Jetro is still very new to VIC tuning scene i think though i'd love to have it, just to get rid of the air flow meters.

Airlfow meters is what makes the PFC so powerful. D-Jetro I assume was made for the american market as they had no idea how to tune a MAF based system. If you want to go MAFLESS get an Autronic because the time/cost taken to wiring in and tune will probably about the same to plugin and tune a D-jetro and at the end of the day the autronic is better.

On a more advanced engine e.g Fully rebuilt , cams/head work and tune the lagg can be taken care of through playing with cam timing , while still not loosing any of the mid range top end punch these puppies deliver.Just take it to a tuner who knows the fine tuning insides and outs of the RB26 and you will be very rewarded.Should be able to see full boost 22 -24 psi at 4500 rpm or just under but they will start pulling hard much lower than this so are still a very streetable turbo set up.

Alot of the gtr forums I visit from around the world rate these huffers above 2530s for there response and big delivery of power in the top end.

On a fairly stock engine Id put a gtss or the 2860R -7 turbo upgrade ahead of these unless of course you are taking it further down the track,these are purfect for a hard tuned street machine.

On a fully worked engine these turbs are good for 380 - 410 awkws

Just my opinion though. :)

one questions I have always wondered is assimung ur've upgraded your turbo, AFM, injectors, fuel pump PFC blah blah and your making a good 300+rwkw...at what point do u need to consider internal upgrades or is this dependant on how hard you drive it? In a street app where you may only trash it occasionally...I'm wondering how the internals hold up over a 1-2 year peroid..on say 1bar or just a little over.

Just intrested as I have a RB25 with the same mods and similar output as this dyno i.e. about 300rwk on 1bar and all the goodies...now I'm wondering how long the engine will last hehe.

I got an r 33 GTR with a built motor and same turbos and im pushing 366 kw at all fours on 22 psi and pump fuel. My car makes 308 kw at 5600 rpm id post the dyno sheet but dont know how

    • It makes you wonder, all these people starting to make a billet replacement head, I wonder if any have thought about trying to adapt tech from newer engines into them. You're already at the full design stage to make a billet head... Why not really spice it up and had some more modern tech into the mix too...
    • Connect all the plumbing up properly. The actual worst part about having the turbo unable to actually build boost, is you can and likely would over soon the turbo if you drove the car (free rev while stationary isnt likely to manage it).   If you do have an air leak as Duncan suggested, you'll have a bad time as the AFM will be saying different to reality.   As you have had the engine out, I'd go over all electrical connections again. If you have a consult cable, plug it in, and see what the ECU thinks is going on. Did you touch the timing belt? If so, double check your timing on the gears is correct AND put a timing light on it while it's idling and see what ignition setting you have. Is the AFM you've installed the one that was in the car previously? You said you replaced seals, what seals exactly? What have you had apart?   From memory when I had my RB25DET with factory throttle, there was two plugs the TPS plug on the loom could go to. One would leave the car running like shit, the other made it work, I think one plug on the TPS area was for something else (an option). It's too many years since I saw that part of the loom to remember properly though.   Is the car idling smooth (as smooth as an RB can)? Does it smell fuelled up?   I have a feeling either timing in timing belt is off, or a sensor isn't right.
    • Theres still skid pan and motokhana days up in QLD at least that are $100 or less. The ones that are ran as "driver training" less so, they're expensive, but just normal skid pan days like SAU ran are still low cost. And thats one of the places I learned to be a lariken, purely by asking for passenger rides, and how people were doing crazy things. Reese gave me plenty of pointers back in the day for skid pan! And yes Duncan, I will never forget your pointers for track work. Especially after Neil got out saying "I am NEVER getting in the car with him again!" 😛
    • 49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.
    • Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf
