DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 what said above is don't under estimate OEM, until you reach the limits. Don't buy gear that's unnecessary for the power level wanted Not sure what you ment buy that, the car has had a lot of work even before the upgrade. I had already maxed oem before I spent money on the turbo injectors computer intake and manifold so that makes no sence. Yes it has an front mount intercooler I just didn't list it. Prob got a few others I haven't said Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7191964 Share on other sites More sharing options...
Dose Pipe Sutututu Posted February 7, 2014 Share Posted February 7, 2014 what did you max it at? also when did you buy that ECU & how much?

GTScotT Posted February 7, 2014 Share Posted February 7, 2014 What manifold is it running? Are you getting adequate flow to the wastegate? IE its not a china stainless manifold with a meter long WG pipe is it?

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 What do you mean max it at? We had flat 11.6 afr. 18 psi and it slowly dropped back to nearly 14 psi may that have been my problem? I can't remember when or how much the microtech was its a plug and play with hand controller. Not sure if it's a china manifold. It could be. It's got 2 pipes that join the collector and joint to 1 pipe to the gate Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7191981 Share on other sites More sharing options...

Prob got a few others I haven't said You bought crappy parts and thought it would add to your power goals. Many others have done the same thing, don't feel like we are singling you out. All you needed to max out the GT3076 was a 3 inch exhaust, turbo, decent modern injectors and a Walbro 255. A decent ecu (adaptronic etc) wouldn't have cost much more than the Microguess.

Dose Pipe Sutututu Posted February 7, 2014 Share Posted February 7, 2014 you mean micro-iceage/Neanderthal? lol fuark man I road tuned a car with it before, I was so close to just calling it quits.. it's was built by morons. 1x table is just RPM vs. ignition (yes there's no load) and there's another table for load and how much ignition you would like to shave off.. LOL.. you said " I had already maxed oem before I spent money on the turbo injectors computer intake and manifold so that makes no sence." So I ask again, what did you previous setup max out at? and what did it comprise of? Guys are making 200kW with stock injectors/manifolds/turbo/coilpacks etc.. with just more boost & ignition/fuel maps optimised (either through a toshi remap/Z32 new ecu, etc.) Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7192027 Share on other sites More sharing options...
Dose Pipe Sutututu Posted February 7, 2014 Share Posted February 7, 2014 and also AFRs mean nothing when your ignition table is complete rat shit, hence I said post up your map.

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 My last set up was Stock turbo 14 psi Cooler 3" straight exhaust Coil packs Blitz boost controller Bosh 040 Tuned remped computer Can't think of anything else, made like 186 kW I think I don't think most of my parts are cheap and crappy. Garret gt3076r .63 Pro gate Denso 880 injectors Greddy copy plenum, been machined flat. So just like a genuine Unsure of exhaust manifold but my friends vl has the same one making 589hp on 20psi Blitz duel stage boost controller was told it was great! Microcrap lt12 well I took some bad advice on that one Turbosmart fuel reg Bosh 044 pump off a relay for 13.8v Can't remember what else. The suspension and underbody is well ajustable everything. The car had cost a lot. I think I'm about 70hp shy of what I thought I was building the motor for. Mark did say the air temp adjustment prob was not in the engine bay and may have robbed me of a few hp?

methz Posted February 7, 2014 Share Posted February 7, 2014 The .63 will flow over 350hp easy as, and a 14psi spring is fine for well over 500hp. What boost control u got?

Ben C34 Posted February 7, 2014 Share Posted February 7, 2014 The comment about unnecessary spend is based on the stock manifolds being capable of flowing enough for your power goal.

DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 The stock manifold was cracked and old and not a high mount set up and needed to for external gate. Boost controller is a blitz duel stage. I can send a pic if u like? I had to change the fuel pump on the dyno because the old 040 let go. It's now a 044. Maybe I just have a really tied motor. I'll do a compression test soon. I know the microtechs are not the best but I didn't think it would cost me this much. Mark said he thinks the .63 is to small and that's y it drops boost off back to wast gate spring pressure.

JordansR32 Posted February 7, 2014 Share Posted February 7, 2014 I would say a restriction or something in the tune, the .63 should go close to 300 but my fall over at top at high rpm Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7192342 Share on other sites More sharing options...
DriftSquad Posted February 7, 2014 Author Share Posted February 7, 2014 I thought maybe some one might have had this sort of issue in the passed. I pretty much just copied someone's setup n thought it would work so I dunno what about a boost leak some where?

89CAL Posted February 7, 2014 Share Posted February 7, 2014 I was going to ask what the condition of the engine is like. Do a compression test and see if you can work anything out. and you definently need a printout of the dyno graph. That will tell alot more of the story Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7192421 Share on other sites More sharing options...

AngryRB Posted February 7, 2014 Share Posted February 7, 2014 not all 3076's get 300kw on 98, mine with gtx3076 0.83 external gate was limited to 278kw on 16psi, it just wouldn't take more timing so a 0.63 would of been even worse, mine would rise 10kw per 1psi, so with 18psi you might get 265kw which maybe quite normal.. mine was running 175psi each cylinder which I thought might of been the reason, run some E85 and you might find it will smash thru 310kw Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7192577 Share on other sites More sharing options...
WYTSKY Posted February 7, 2014 Share Posted February 7, 2014 You should get more power then that - mine is 284rwkw but with a little bit more timing I have gotten it to 294rwkw however on some loads would ping so safe at this. This is just on straight 98, my gate is welded on the back of the turbo housing. Similar support mods, obvisously different ecu and tuner but for your reference: Link to comment https://www.sau.com.au/forums/topic/438770-rb25-gt3076r-mods-made-low-power-on-dyno-tune-why/page/2/#findComment-7192605 Share on other sites More sharing options...
AngryRB Posted February 7, 2014 Share Posted February 7, 2014 so if your on 19psi and hes on 14psi, what should he be making with average to slightly pulled back timing? 230-240kw?
