Yes, the second Bosch pump activates on high load, and I've been told the 416 pump can be downgraded since it only feeds the surge tank now.

I had 257 kw using 98 fuel: 525cc XSpurt Injectors and 255 LPH Pump at 20~18 PSI. Told my tuner I just wanted E85 and see what it can do. Tuner said not enough fuel pumping and had to upgrade to Walbro 416 LPH . End of the day it made 295 kw 21PSI on E85 using 525cc Injectors at 100% duty cycle In my experience, never go weak on fuel. I now have XSpurt 1000cc + 2xBosch 044's in a surge tank, the same 416 pump in the stock tank. Don't limit yourself just to upgrade it again later

good enough

Its been done to death. Many forums about it. Anyway I was in your situation before. I gave NPC a call, they recommended: heavy duty cushion button rated 400rwkw.. more streetable.. or a carbotic button rated 450rwkw.. abit more aggressive on street

My 3" HKS Hi Power Silent makes high power and is silent. I can't rev match properly because it's so quiet, I hate it So as my daily, I've disconnected it after the cat with a 1mm gap. Lol Makes 348 rwkw on the dyno, however, without the exhaust (disconnected from the cat), the car made 365 rwkw I've had 3" varex previously. Mine lasted about 1 year(driven daily) and the gears got grinded off

Turn up the boost? Check for more leaks? I had similar issue. Started boosting 18 instead of 23. I fixed it by changing the BOV and hoses. Well I think it was the BOV; I was playing with the BOV and intake pipe at the time. I also shortened the wastegate hose which made it open too early, then changed it back.

Awesome. How much all up - $550? It's the first mod I did on my N/A back in the day. Very handy passing cops, going through RBT's, driving inlaws, being taxi boyfriend, talking, etc. With mine, adding a pod makes a difference to the exhaust sound. better inhale = better exhale. or maybe a high flow filter will work on your airbox. I never tried it though. Both is illegal here in NSW too. I got away with it for 3 years and I got defected for Pod filter. They said nothing about the exhaust. Now using the airbox since that day and my GF driving it now. Just don't spend anything else until you get turbo skyline, you'll need the money, trust me! been there done that! Goood luck

What muffler though??? I looked around and no one advertises any photos of muffler internals, only tip size and inlet size. Was thinking to straight pipe my resonator and put on a good muffler, but couldnt find one. I was quoted $1600 for a 3.5 inch custom exhaust, but was out of my budget with my new setup. I previously hit 295 kw with my old setup and was hoping for over 300 like what others got with the same turbo. I only realized later that it's all because of the kakimoto resonator! Have a look inside before you chop it. Might not be the same. What exhaust? Yes, the step downs make it quiet and better sounding. Kakimoto was too restrictive and too quiet, and it gave a "SHHHHHH" noise on WOT. The HKS one sounds real nice and soothing, even on WOT. I might keep it and install a exhaust cutout just for track days.

Have you had a look inside your Kakimoto Muffler? My old kakimoto has 3 inch to 3.5 inch piping but shrinks to 2.25 inch at the muffler. The Resonator is also the same. The cable tie is measured 2.5 inch. As you can see the Kakimoto ones shrink down even more My car now has a HKS Hi Power Silent catback and it shrinks to 2.5 inch on the resonator and muffler. I need something else. My old XForce one shrunk to 2.75 ~_~ come on! My dyno graph shows the HKS catback restricts about 16 kW and 187 rpm response. That's with my screamer pipe already relieving pressure. I'm sure 2.25 inch would suffer more. Even worse if the gate is plumed back or internal.

Similar thing happened to me 2 weeks ago. Boost suddenly slow. Full boost at 4500 rpm instead of 3600 rpm Manifold stud went missing Turbo spins fine Hardly any shaft play Compressor wheel looks fine Mine however, made a noise. When the turbo was removed, the turbine wheel was checked - a fin was chipped and another is cracked Hopefully its not the same issue. Since yours isnt making a noise (is it?) and also a big jump from 4000 to 6000 then I'd also say its your gate being partially open. Good luck

As mentioned in my previous post #1451, I've tried Toyo R1R and Nitto NT05 @V28VX37, I got my R1R tyres from St George Tyres. (NT05 from Taleb) Toyo R1R and Federal RSR was offered to me there, but I chose Toyo due to stock for 255/40/17. I really wanted to try federal RSR but they only had 235/45/17. Based on drag racing with my R34 GTT, Toyo R1R is still my favourite grippy tyre. 220rwkw NT05 13.4s.... 2.2s 60 ft.... 5k launch 220rwkw R1R 13.2s.... 2.1s 60 ft.... 5.5k launch <<<< needed 5.5k because so grippy 295rwkw MTSC 13.1s.... 2.4s 60 ft.... 3k launch (horrid) 295rwkw R1R 12.5s.... 1.99s 60 ft.... 5k launch <<<<< my best 1.99s 60 ft because so grippy This is my daily so I use these tyres on street and at drags. IMO, R1R lasted almost twice as long than NT05. @Hadouken On my mates 260rwkw R34, NT05's couldnt handle the power. But AWD is a different story Only me and my RWD friends(GTT, GTT, 335i, XR6T) complain about traction, but my AWD friends are having no problems (Ralliart, WRX) with >300 treadwear / $60 anybrand tyres I don't do track / circuit, however, I do enjoy twisty cruises with mates. Both NT05 and R1R performed well at Palm Beach / Old Pacific HWY. I didn't dare try any twisty cruises with Mickey Thompson Street Comp - Didn't want to die These couldnt grip on simple roundabouts.

I have aids

Update! Replaced tyres yesterday. Couldn't get RSR or NT01 due to ordering delays. Tyre shop had R1R in stock. Mickey Thompson Street Comp 245/40/17 vs Toyo Proxes R1R 255/40/17 295 RWKW R34GTT Manual 245/40/17 Mickey Thompson Street Comp From 0, not launching: first gear spins as it reaches 3k/4k rpm on WOT. Second gear spins before it reaches full boost. Starts spinning at 17 psi according to EBC Third gear holds abit, but it screeches during high RPM- sounds like someone braking hard. Launching at 3k and will spin as RPM rises. 255/40/17 Toyo Proxes R1-R From 0, not launching: first gear does not spin, all the way to redline, reaches 20 psi Second gear does not spin at all and reaches full boost 22 psi on WOT. Amazing pull. Third gear no issues. Launched at 5k rpm on street. Tyres chirped.. Good pull.. did not Bog down.. Very happy with these tyres at 295 rwkw.. 4.X seconds 0-100 I'm ready for Eastern Creek R4R ---------------------------------------
