I think that is the same hub dyno James is using for the Euro project - if so power/torque figures are at the hub, not at the wheels. The wheel figure is typically lower by about 10-15%. either way very nice...
thanks for the kind words. it was a task and a half... but completed in the end
i think the toda cams are the spec C.... all i go by is the cam lift duration which is 295 degrees on intake and about 275 degrees on exhaust
i have taken some shitty photos of my car and as you can see, 100% clean stock body and rims.... at the moment its a sleeper and will probably never see a body kit as i am not huge on the idea of putting one on. rims will be changed as as soon as i get back from japan in late july for some badly need traction.
and hopefully in japan i will be able to source a better after market or even jdm intake manifold and intake. As some of you noticed power does die in the top end at about 8700 - 8800 rpm. this is due to the more restrictive intake manifold in the audm type rs. I have thought about itbs, however there is not really enough room to run enough of a runner length, hopefully i will be able to find something
yfin - not to be a smart arse, and all due respect with the next question, are you speaking from experience when comparing dynos? granted that it is a hub dyno vs a roller dyno, however i cannot really see that there would be much of a difference in friction of tyres to steel rollers and hubs which are attached which mimmic tyre contact to road. Both dynos, when used correctly are there not to just measure power out put, are also there to provide load on gear box and engine when tuning a vehicle, load meant to be close to what would be experienced on the road... providing indications of when in the rpm the vehicle will need more fuel added to the mixture, or more spark and when to advance timing. I dont even think it is really possible to obtain the same power figure on 2 different dynos at 2 different workshops??!
at the same time on a roller dyno, if i vehicle is strapped down to tightly it will create more load on the tyres, making the engine work harder to spin the wheels.. hell even tyre pressure can come into effect on a roller dyno. i will try and get it on a roller dyno and see what happens.
however, i didnt enter into this project to see if i could have the most powerful dc5r. i couldnt care less about power figures and how much power my car has. all i wanted to do was impress myself.... and it has exceeded all my expectations. and the project is far from being finished. i still have some suspension shopping to do.
Remember though its not how much power you have, its how well you can use the power that you have got.
if i was after outright power i would have bought a r32 gtst, ripped out the rb20 and slapped in an off its head rb30 bottom end with a rb26 head and a monster turbo and be running 400kw + without breaking a sweat.
I am extemely happy with what i have and will post up videos, quater mile times and track times as soon as they are done. and everyone in vic will be sure to see me out and about at coming meets and around on the streets
