Sports compact one of the biggest event of the year was on today and i was there representing us 300 drivers all going good till i got on tha dyno where i was expecting 320+ rwkw seen as thou it was a hot day and that would of been good enuf for fastest v6 that entered the dyno challenge but i pulled a very shit 279kw that made me the slowest, can anyone build a vg30dett right out there, is it our motor or is it the ppl we trust in to put the numbers down on paper with out the lies and BIG dollars spent!!!!!
Umm there are so many factors that effect peak power What have you had done to the engine? 320kW is relatively easy with th VG30, if it is supported correctly with the right ancillaries. Any way peak power says nothing about the engine, and even less about the car.
dieseldave i never got to thank you awhile back you helped me out last time i had issues with my car cant remember with what there's been so many. yeah Ive done a fair bit to it, . Argo Rods . J E Pistons . ACL Racing bearings . Cams . 2x GT28r . plasma man inter cooler . B & M auto cooler .Uas oil cooler . custom uas radiator . twin 2.5 turbo back exhaust . built gear box (to handle the extra power) . Nismo thermostat . E Boost 2 (set at 21psi) . duel k & n Pod intake . new oem water pump . valve springs That's just the performance mods that i can think of , Ive heard of mods similar to mine and there reaching 350kw. The reason why i am more upset about it yet is, firstly the car has not even reached 3000kms since Unique rebuild (300zx specialist). I was told by my mechanic on my last visit it ran 337rwkw on his dyno but "he couldn't find the read out" when i arrived to pick the car up and after today's embarrassing performance it ran 279rwkw.
maybe your printout this time was accurate, its a decent figure, dont be such a primadonna, you couldnt tell the difference between 280 and 320+rwkw so you need your arse dyno re-calibrated too. Im so sick of people crapping on about 350rwkw, a well set up, well driven 280kw car beats shit box 350kw dyno queen crap every time dyno sheets are for tossers, you were obviously pretty happy with how it ran before and how it performs on the street, so who cares what a dyno sheet says?
agree with rollin and dynos read differently depending on what is programmed in but you should be doing better numbers than that at 21 psi with gt28r And for the record those big name upgraded parts you have arent going to give you any bigger numbers just strength.
Is that 21psi on stock injectors? Or larger ones? Not being wierd or nothing but i didn't know pistons and rods etc give better performance power or anything, all I can see for actual perforance mods is the turbos and intercooler and exhaust. Anyways 280KW's is nothing to snear at!
Can't remember what size injectors you are running but they must be at least 700cc with that boost pressure. I suspect that you might be pushing 21psi out of the turbos but the engine is not seeing that. 21pis with cam work (unless the cams are not the best) should be making some good figures. I would suggest that if everything is working well that there is a restriction in the pipework. Whether it be a kinked pipe or hose, or a design restriction such as in the intercooler (but that is a known brand too). ???? Or, it could be just an incorrectly setup dyno as you said that the car still drives well. How did they strap it down? And, do you have a print out, especially the torque? It will explain a lot. Oh, and you are welcome. Happy to help.
sard 740 injectors i have, i was just mentioning engine mods so you don't think i just waked on some bigger turbos and hoped for the best,
280kw is quick yes not for the money i spent thou ill break it down for ya if you went to a candy shop and asked for 5 red frogs and tha dumb mother fuker gave you 3 you'd wanna know weather he cant count or he just thought you would notice and believe me I'd notice. and by the way 280kw vs 350kw could be the difference between coming 1st 2nd winning or losing and if you drove a 350kw as hard as you drove a 280kw that's the difference right there 280rwkw came 2nd "doesn't matter if you win by an inch or a mile winnings winning"
epic lols at the fast & the furious quote. That's just nasty The thing is, let's just say you WERE given 3 red frogs instead of the 5 you asked for. YOU DIDN'T NOTICE until someone (albeit something, the dyno) told you that you 'only had 3 red frogs'. Who's the 'dumb mother fuker' now eh? :rofl:
are u serious with that post? candy store comparisons and F &F quotes? Let me break it down for you, how could you not tell the difference between 280kw and 350kw? i can usually guess a zed when i drive it to within about 20hp If you had walked out with a dyno sheet saying 340kw and the car performing exactly howw it is, would you be happy? yeah probably since you;d have a dyno sheet top show off to your goose mates. my point is to forget the dyno chart, if the car perfoms how u want it to then be happy.
Im making 311rwkw at 17psi with stock internals and gt28rs's. Get use to the power quiet quickly. Will post a dyno soon. You should be making alot more at 21psi
You're comparing two peak power figures that were obtained from two different dynos. Of course there's going to be some variation. The discrepancy doesn't automatically mean your tuner 'robbed' you of some sweet, sweet kilowatts. Not only that, but the hot weather would have had an effect on power output on the day of the competition. And why are you sore about losing a dyno competition anyway? Those things are for posers. If you were happy with how much power your car had before the competition and it hasn't lost any of that power since then, why are you disappointed? The Fn'F quote was comedy gold, by the way.
It doesn't perform for what i spent on it no, but if i have never driven a car with 340kw or anything close to it how would i know the difference and not being present while the car is on the dyno i wouldn't of found out till today! where you on the other hand consider your self as some backyard zed specialist driving other ppls cars doing boggy work being a mechanic you should know the difference your in that trade who knows you might be good at what ya do you defiantly talk like a mechanic, yeah i am serious with that post you talked it up like a smart ares so i gave ya smart ares reply. what im saying is true right! you do understand that when i ask for some numbers ok he couldn't deliver those its not in writing anyways but then to hide it and lie that's what im more dirty bout.
stock internals i blow my motors bottom end with stock standard turbos but i drive like a maniac thats dam good at 17psi i should of went for the rs's
i talk like a mechanic? good to know. you talk like a fully sik douche bag. and what "boggy" work have i ever done? If your car is actually running 21psi then yeah those numbers seem low, there are a number of things that can cause that, and even more reasons why a car will do different power figures on different dyno's Instead of shooting your mouth off and blaming your mechanic like some spoiled kid, how about a serious post with no vin deisel quotes asking for reasons why your power output would be less now than it was before and how much power your car should be making now with the mods you have
