Yea, the tune is complete and i am stopping the tunning of my car as a whole now. no more money wasted on it. alone on this mod has cost me over 200,000HKD. previous mods i cant remember but were less than this for sure as they were so big scaled. the car only cost me about 175,000.

here it is, any of u dyno readers take ur shot.

My name is Jason and I need to learn to resize a picture!!!

*edit*

can someone convert the PS to HP for me please, and also gimme the link to the converter
 
HP=PS/1.0139 -> 463.55HP @7600rpm or 345.81kW ATW. Nice. You can see the boost kick in at around 4500rpm
 
Jason - you're insistance to post massive h-scroll breaking pics is really getting annoying - sort it pal!!

I completey agree! Resize the pictures before you post them!!! :censored: It would take you all of 2 seconds to do and would save a lot of people the hassle of trying to scroll through some massive picture. :thumbsdown:
 
I fixed his pic.
 
Respect!
 
Slap some moondisc wheels on it and you'll see about 475-480.
 
Heh. I couldn't even make sense of that dyno chart. What places in North America usually have a dyno thingy?
 
i dont think i will mod it n e more i mean its more than enought for a road car. i may up the boost to get 500HP.

someone was suggesting to get a lighter fly wheel? how much HP u recon that get?

plus 500Hp sounds better to say and has more than most ferrais lol. so i can now say"my car is faster than a ferrai and it 500HP" :thumbsup:

btw which "big name" supercars have around the same or a bit more HP than me?

e.g. enzo or carrera gt or lambo's. i tihnk i am only a lill off the gallardo yeah?

Ligter flywheel won't give you any hp(methinks), it just makes the engine response quicker. e.g. if your engine is idling at ~1000 rpm on neutral and you stomp on the throttle it takes less time for the revs to rise.

I think gallardo has ~500 bhp, so not much to go...

Few others that have more power(the figures are around those figures, my source is not the most reliable ones).
AM Vanquish 520bhp
Ferrari 575 510 bhp
Ferrari Scaglietti 540bhp
Koenigsegg CC(not big name, but for comparison) 655bhp
Pagani Zonda also has more power, can't find the figure, tho[edit: 550)...
 
yeah i might just make it 500 and see how long the turbos last b4 i go for some bigger ones. i run on lower boost so that they last long tbh. its all about the moeny isnt it. *sigh*

when i do track i recon i can get it to 600? or more with a crazy boost. coz the track days i watched b4 where normal people with tuned cars go only do like 5 lap races so it allows crazy set ups for max. hp :>

i seen cars in JP with the same turbos makin 630 PS or HP so theres a bench mark. with 200cc more in my engine, u recon i can make 650?
 
but you have to know that if you put in bigger turbo's... yes you have greater power but on the other hand... you have crazy turbo lag like what the F40 had... bigger turbos take more time to spool up

Maybe you could make it up to 650, but it's all with the risk of blowing up everything and being forced to cough up the cash to replace everything. I would not push it, but then again I'm not the one who owns Skyline here :lol:

I would propably take the car to track to test the car before doing further upgrades on the engine side, to see if there's real need. On streets you'll never need more than what you have now.

edit: Oh, and andyhui also has a valid point on the Turbo lag. F40's lag was nothing compared to XJ220's :lol:
 
the ECU can't change the Turbo lag time... the turbo will take just as long to spool up but the boost would just be electronically limited.... from the dyno graph... I can tell you have some serious turbo lag on your car... comes in at about 4.5k compared to 3k on my old Subaru and 2.8k on my RX-7...
