Mark-32

I assumed the figure was so high as its rwd only? To begin with the boost was at 24psi but the boost curve flattened off aswel as the power curve around 6500rpm making consistant 430 odd rwkw. The tuner asked if i was happy with that and I said i wanted to add a litte more boost at the end of the rev range to see if the power curve would continue upwards in the direction it was heading. He then snuck more boost into the engine up top and thats what happened. Im stoked with it, haters are guna hate either way but it is what it is.

I was suprised myself but I have dyno papers from when it was first run in on dyno on 14psi, then tuned on 21 psi on pump fuel, then now on E85. All the dyno runs today were in 5th gear as 4th would just bag the tyres. Spec list of what i can remember in no particular order is- RWD Rb26 conversion in an r32gtst r33 5 speed hi octane 11 litre sump (rear head drain, nismo oil air seperator going into main catch can that drains to sump.) 1mm restrictor 2860 -5s big trust intercooler (unsure of exact dimensions but its over 100mm thick and pretty huge) exhaust is stainless split dumps into 3 inch y pipes into a 3.5 inch sidepipe no mufflers cams are tomei 260 10.8mm lift?? nitto/je pistons nitto I beam Rods Arp stud kits throughout balanced and blueprinted nitto 1.2mm head gasket vipec v44 ecu internal boost controlled fuel system is 1v 044 lift pump 2x 044 external out of surge tank feeding hicas lines greddy twin entry rail aeromotive fuel reg ID1000 injectors

Did a firmware upgrade on the vipec that solved the misfire problem i was having a few pages back. Went back for another tune it made 486rwkw on e85. Engine is rb26, -5's running 26 psi Can any tech heads tell me how to upload the dyno graph as its over 2mb ??

It would be a v44

I will take the bonnet mate my numbers 0428457841 send me a text I may take the gaurds aswel

Thanks bud.

Old thread i know but can anyone put me in touch with Paul from red r racing. I'm having this trigger issue at 5000rpm on my rb26 and need to get hold of a 24 slot trigger disc for my cas. I'm having the problem as im running a vipec v44 ecu. For people's information we tried haltech platinum series ecu and its able to read the signal no problems so its an ecu dependant problem

Here's a couple of bids of the misfire

Does the problem with the link sound like the problem I'm having and start at a similar rpm area to me? I'v just done a firmware upgrade on the vipec I'm hoping this may solve it but I'm doubtful

http://www.skylinesa...30/page__st__20 It even says there somewhere haltech may not do it while vipec will. Could this be my issue do you think and explain why the haltech fixed the issue?

it was done in 5th to try get more traction it was more consistant for trying to diagnose the missfire. We even tried going half throttle through to 6000rpm then 100% throttle after the missfire area of the rpm and it made it better. As soon as in was full throttle is would missfire exactly the same

Any idea of what sort of a power increase do you think i should expect once i solve the issue spins to 8500prm and 25-26psi?

Im not sure what you mean? The dyno runs were done in 5th gear. I cant drive the car the miss is always there and cuts in at exactly the same revs evrytime and its that bad it doesnt recover and continues throughout the rev range. It has to be the ecu itself as the miss was completely gone with the other ecu on a pulp 33gtr tune.?? Spent 5 hours on a dyno checking valve springs trying evrything possible, tried running it super rich super lean made no difference the miss was always there couldnt even do any power runs it wpuld just break down

Went through all of that mate had vipec guys on the phone etc it was nothing to do with that at all. Funny thing i didnt mention was when we went back through some old dyno graphs from months ago it seemed the car suffered the same sort of issue at the same revs but it was not noticable as a misfire until the power was increased with the e85. Iam a big fan of the vipec and would really like to get it sorted because as you can see from the dyno graph once the misfire is fixed and more boost is added it should make alot more power

whoops that was the pulp dyno graph

Joined the 400kw club but Im chasing some answers to some issues we had along the way if anyone can help......?????? The car is a r32 gtst with rb26, dash 5's, vipec This was the pulp tune sharedmedia=gallery:images:83182] Went to E85 so changed the injectors to id1000s and went for another tune......... As you can see the car was suffering a fairly severe misfire at 4500 which after changing plugs 3 times, coil packs, cas etc had myself and the tuner completely stumped. The misfire seemed to be heat related as it got worse the hotter the engine got and even on lower boost the misfire was still there at the same revs. The car runs a vipec plug in and after pulling our hair out for 5 hours on the dyno trying to diagnose the problem and out of pure desperation we put a haltech ecu in the car with a map from a gtr and the miss was gone. Has anyone ever heard of this issue and have any ideas?

Injectors sold, mods please remove this cheers.

Done under 2000km on new engine. Reason for sale is going to e85. $600 0428457841

my plan is to relocate my battery to the boot and mount a big can where the battery usually goes in the engine bay, also running the rocker breathers into the same can and relocating my rear head drain to the other side teeing into my rear turbo drain. The catch can will act as the vent running to the driverside of the sump also allowing any oil to drain back when engine is idling or turned off. Any thoughts on doing it this way or any better ideas?

Thanks everyone for the input but in that last diagram you have your catch can draining back to the passenger side of the sump. I do not have a fitting in that side of my sump and i dont have much room on that side of my engine bay to mount a can. You have your sump breather and rocker cover hoses all running to the same can then draining back.Another thing i forgot to mention was the oil that was pushed into my catch can was very black and thin compared to clean looking oil on the dipstick. After a full day at the track i ended up having to put over 4 litres of new oil in the engine and chucked the oil that got collected in the can.
