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.

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.
