I run -7's with a shitty exhaust and stock afm's. With id1000's and a walbro 400 fuel pump I make 325kw on 20psi with E85. If I fix my exhaust and chuck some bigger afm's on I'd probably crack 350kw.

It'd be much easier to do it with -9's and I don't think there would be much more lag involved.

What exhaust you going for?

Gospel huh? Considering im making a lazy 250rwkw @ 12psi with GT-SS, and I know of at least another 10 cars making over 300rwkw (between 300-330rwkw) on 20-22psi… On various dynos to boot (more on th

Ants is right, lag and no responsiveness should be a crime or atleast punishable under the anti gay laws. It's beyond me why the hell people r so intent on makin there car run like a pig, and if peop

Ok, had a play.

Your car is obviously tuned in 3rd gear going by the speeds. It's a bit rough but you get the idea.

3950: N= 176 P= 215

4400: N= 252 P = 300

4800: N= 306 P = 375

5244: N = 326 P = 415

5644: N = 344 P = 445

6100: N= 350 P= 460

6500: N = 342 P = 472

Take into consideration how they were loaded up for the runs and whatnot.

Just out of curiosity...

I have a set of -5s on my std RB26DETT and i'm only making 300kw on 22psi...

The things I noticed are my actuators are set at 8psi and I have 600cc injectors coupled with a Walbro 255 pump.

Are these going to be an issue or is it a tuning issue?

EDIT- Using 5speed from RB25 and 4.08 S14 Diff in an S15

Thats what im trying to figure out! My injectors hit 100% duty cycle on full boost thats why I thought my pump or injectors were maxing out but doesnt make sence I should be making 300kw on less than 20psi id have thought...

Previously I had valve float but that has been rectified.

What exhaust you going for?

Nothing at the moment as I'm content with the power. I think I'll get more gains if I upgrade my actuators 1st and see how I go.

Eventually I'll rip the cat out and the 3" exhaust and replace it all with 3.5".

Well the 255L was an upgrade on the SR lol. What should I be aiming for when I buy a new one?

The pump provided its getting the right voltage should have an issue with that power. I think it's time to put your inspector gadget hat on and start investigating.

I'd say, once again, attention to detail on the setup is where the better results are. Big, size matched exhausts blah blah.

Got a sheet Nick?

Exactly.

I had 340rwkw with -9s on 98, but it wasn't a stock engine - and that is where the extra bits/gains come from

If that was the case then the run would be only going to 5000 ish rpm. Unless the speed scale is out.

Who knows ay

Soon find out when I get it retuned

It works that's all that matters :P

I see!

An actuator upgrade will do it good.

Yeah, if you want to get over the 350 rwkW mark, go 3.5".

Exactly.

Other thing is the turbos are REALLY laggy.

I get 18psi by 6000rpm and power drops off completely at 22psi at 7500rpm so theres no point revving past there...

      yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Yeah I would like to try and get a ADM car to reduce issues with insurance. I've decided if I end up getting this car I will set it up to be a sleeper build, leave it looking stock/dad spec on the outside I wonder if you can just drop in the 400r/Red/Z ECU or better still use a flashing tool to copy the map off one. Backup the factory map and then flash the 400hp cars onto the 300hp cars ECU?
