GTS-t VSPEC Posted August 23, 2004 Share Posted August 23, 2004 I'd love to know Paul's secret to 450HP. I'm nearly there - with similar turbo (larger rear housing). Dude did you have an exhaust on your car when you got the 450 ? This is 23 PSI - ( get no difference in power from 21 PSI upwards - tried 25 PSI today and 2 rwkw less - same dyno) B-man, That was with a 3" exhaust and no cat, 45mm external wastegate. We found that pushing the boost much higher wasn't producing anymore power either, but we're unsure whether it was the turbo or the cams running out of puff. We'll be changing the cams soon, and failing that may try the GT30R.

nv033 Posted August 23, 2004 Share Posted August 23, 2004 ever been to the drag strip "GTS-t VSPEC" avg power is huge and should equate to huge mph and it doesnt lie for those of u who may be thinking this....so u can eliminate variations between dynos.....i'm guessing 130mph?

BU5TER Posted August 24, 2004 Share Posted August 24, 2004 I had good average power and 128mph, nothing like GTS-t VSPEC though, i'm thinking around 135mph at least Link to comment https://www.sau.com.au/forums/topic/49209-post-up-your-best-dyno-graph/page/2/#findComment-987857 Share on other sites More sharing options...
BU5TER Posted August 24, 2004 Share Posted August 24, 2004 maybe SST Steve can help here, is the reason Wolfs can make the power they do on standard injectors or standard GTR injectors because of the way they fire the injectors, Is it something along the lines of 2 squirts per fire rather then one (sorry no idea how to explain what I mean but I'm sure Steve will understand:) ) Link to comment https://www.sau.com.au/forums/topic/49209-post-up-your-best-dyno-graph/page/2/#findComment-987859 Share on other sites More sharing options...
N I B Posted August 25, 2004 Share Posted August 25, 2004 We are replacing the gearbox then of to the drags with a new set Street ETs. Last year this car was running 411rwhp on stock pistons and injectors and ppl said that we were lieing then the car went on one of these ppls dyno and made 436rwhp.

My sard 550cc injectors read 80% duty cycle at 320rwkw so 330cc stock injectors will be reading 120% duty cycle at those power levels. Anyway highest i have got with GT30/40 0.70 comp and 0.86 rear is 322kw@wheels at 1.4bar stock internals at selectamaz dyno day which i havent got a graph for either.

GTS-t VSPEC Posted August 25, 2004 Share Posted August 25, 2004 No, no longer on stock injectors, we're running GTR injectors now. When you get a graph I'd be interested to see the difference the two housing's make between our curves.

INASNT Posted August 25, 2004 Share Posted August 25, 2004 car comes on boost hard at 4000-4200rpm with the 0.86 rear and lights tyres up 2nd and sometime start of third, so i hate to think how the power delivery with a 0.63 housing gives. I got a graph from autosalon where it pulled 312kw@wheels indoors in hot conditions. The 322kw@wheels was in a 12 degree day outdoor dyno.

GTS-t VSPEC Posted August 25, 2004 Share Posted August 25, 2004 Either my tyres must suck or my power comes on more aggressive, cause I light up all through 3rd, and the start of 4th:( Link to comment https://www.sau.com.au/forums/topic/49209-post-up-your-best-dyno-graph/page/2/#findComment-988754 Share on other sites More sharing options...
INASNT Posted August 25, 2004 Share Posted August 25, 2004 0.87 housing and 0.63 housing is quite a difference!! I like it much better when i accelerate and i am actually moving forward and not just sliging along with wheel spin. Have you tried a bigger housing? you might see more power with more boost then as ur exhaust housing must be causing a restriction Link to comment https://www.sau.com.au/forums/topic/49209-post-up-your-best-dyno-graph/page/2/#findComment-988810 Share on other sites More sharing options...
GTS-t VSPEC Posted August 25, 2004 Share Posted August 25, 2004 Yeah, I have thought about changing the housings, but I don't want to loose the nice spread of power I have. May try a GT30R on to see how it goes. Link to comment https://www.sau.com.au/forums/topic/49209-post-up-your-best-dyno-graph/page/2/#findComment-988815 Share on other sites More sharing options...

GTS-t VSPEC Posted August 25, 2004 Share Posted August 25, 2004 This is the 2nd lot of suspension I've had in there, but eitherway it still baggs up. I'm hoping to put aftermarket cams in soon, so we'll see what difference they make to the power curve.

FATGTS-R Posted August 25, 2004 Share Posted August 25, 2004 I have now been convinced as to what people have been saying for a long time, Dyno graphs dont mean jack shit. My car is currently in a Bayswater workshop in VIC getting some mods done. The workshop in question has a brand spankers DD 4wd dyno. This workshop together with APS built and developed a twin turbo kit for the LS1 engine. On there own dyno the car made 460rwkw. On the APS dyno it made 510rwkw both times on RACE FUEL. The car recently went interstate for a Holden vs Ford gig and won the dyno comp with a ridiculous 650rwkw on PUMP FUEL. Go figure. The owner of the workshop showed just how easy it is to make a dyno read a lot lot higher than it should. One example was to "manipulate" the dynos temp sensor for a higher reading in shootout mode. The next example, and one I did not know about was that supposedly each car that goes onto the dyno is meant to be calibrated so that when the car is doing 100km/h so is the dyno. He ran the same car twice in a row, one time with the dyno geared correctly and once with the geariing tweaked a tad. The difference was amazing, the outright power wasnt that much higher, but higher nonetheless but the average power was about 20kw greater all the way across. Overlapping the two graphs you would think they were two different cars. So to all the people who write "dynos are just a tuning tool and power graphs should be taken with a grain of salt" I 100% agree with you.

May try a GT30R on to see how it goes. GTS-t VSPEC or Steve-SST, which GT30 core do u have now, can u provide the CHRA number? it might be worth your while to go up to an A/R .82 exhaust housing.
