Dyno Tuned With Gtss Turbo's

[Flaps]

the gearbox can handle more power than that. just don't abuse the gearbox and don't put a solid centre clutch in it, i know from expereince

Solid centre? Me dumb

[GTR032]

Do you have a fuel pressure reg?

How do stock injectors induce the 'lag'? Would be good to know what duty cycle your hitting - you don't have a h/c?

252rwkw sounds pretty close to what i made on stock turbos. Do you have adjustable cam gears?

<{POST_SNAPBACK}>

No i dont have a regulator or hand controller unfortunately.. the inducing lag bit didn't come out quite right. My tuner said basically if there could be more fuel put in down low it'd spool it up quicker, but the stock injectors are pretty close to their limit and pushing them closer would be living dangerously. So, if I did the fuelling upgrades im sure we could get it spooling quicker, how much quicker I got no idea.

Yeh got HKS cam gears..don't think they were adjusted with latest tune for new turbo's.

I can't see how you can be at 100% duty cycle down low? that doesn't seem right. i can see them being at 100% at 8000rpm, but not at 3000 to 4000? I could be wrong though.

[GTR032]

I might be interpreting what my tuner said wrongly..anyways, it could spool quicker. How much i don't quite know. I'll find out then post up.

Exactly my thoughts. I don't know much but i would assume at 4000rpm, they only have to fire half as much as they would at 8000rpm. From what i have seen, injectors usually max out up the top of the rev range.

We need someone more knowledgable to answer

Fuel pressure reg should help get a little more out of the injectors. Only a couple of hundred bucks.

Just don't buy a solid centre clutch, thats all you need to know. Go for a sprung centre, most are sprung anyway.

i know that gtr gear can handle more power....but jono think that his gear box is stuff...cant run....

My Gtss's spool up to 1.2 bar at 3800 under load with stock cams and no cam gears ( 550 injectors go to 92% duty ) .

Jerry: any idea what the difference would be between your setup and GTR032? Just tune or something else?

Well , i have a 34 engine , almost new , tune of course is different well under 12-1 at 11.5-1 , i wont run 12's on a stock engine .

I dont have cam gears or dump pipes but the 34's have s/steel dumps not cast and i have 550 injectors , the other thing mine will only make 240 awkw .

I'm not after big power in my setup , i just want a quick street car not big dyno numbers .

I did 11.8 @ 118 mph a couple of weeks ago with a bit left in her still , i'm happy the way she goes as i have plenty response , almost like a stocker and 34's are more responsive that 33's and 32's (if all 3 are stockers ) .

Actualy if i had steel wheel turbos i wouldn't bother with the gtss's , thats the reason i tried to buy an NUR M-SPEC , maybe next time !

Gtss's are not cheap but in my opinion ideal for a stock engine but stock injectors would be right on the limit , thats why i went for the Nismo 550's ( again not cheap , you can get sard much cheaper ).

[ferni]

Can injectors have anything to do with lag like GTR032 mentioned earlier in this thread?

Why are 34's more responsive than 33's and 32's stock?

No they shouldn't have ,as they supply all the fuel needed, i dont know if the cams are the same in the 3 cars , so that maybe one reason , different turbos is another and who knows they may run more timing as well as better dump pipes . Ports and valves i think are the same but i never had a 34 head off the car so i cant say for sure , i'm only going on what others have told me . I know from experiance they run more boost .

[ferni]

Cool, thanks for the info Jerry.

[wrxhoon]

Are you going the gtss road Andrew ?

All you need is the turbos ,dumps, power f/c, ebc and 550 injectors , as long as you have a good donk ( do a compression and a leakdown test to confirm ) and you will have a much quicker car and almost as responsive as it is now .

[ferni]

Yep turbos and pfc are on thier way.

I had the pleasure of being a passenger in it for 1.5hrs the other night and I must say that it drives very well. It has better response/power under 3000rpm than my R33 GTS-t did with the stock turbo B)

Car's going pretty good. No dramas since new tune

Just got to fix up an ongoing tailshaft type vibration. After that will take it down to WSID to get a time.

[ferni]

you got another tune?

...Deadset? Thats pretty damn cool. I sure as hell dont want to go for a ride in Fernis car when its finished...aint enough Prozac getting around

[Beer Baron]

there there Troy... Just put on that GTR bonnet etc, and get three gauges for the centre console and sit in the driveway making car noises. then you will feel like a GTR owner.
