2k -6k??? no offence to mikey's car but he is making 80bhp at 2k and doesn't hit peak power until 3.2k then the graph stops at about 4.2k so we can't really say whats happening after that but it doesn't really seem to be letting up power wise.

and to say the two graphs look the same is crazy, stevie wonder can see they are different!!

the graph posted above hits peak torque at 1500rpm and holds it to 4000rpm where it slowly tails off, mikey's torque graph is like a recreation of Mt.Everest.

This is just somebody's idea of a good graph not a real graph as no car could produce as smooth a bhp/torque line as that plus how many 1.9/2.0 PD diesel cars do you know that rev to 6.5K ?

Power below 2K needs to be improved and should be sorted when the new turbo set up is fitted. It is comments/suggestion like the above on how to improve my car is more what i was after when i posted the graph not get into some petty slagging match. My car still has a long way to go before it is finished/blown up so constructive criticism / suggestions are welcome.

Do you have standard intercooler? Did you spend more than a new s3?

it's real, just slightly...smoothed out. but no, it's not a diesel graph:)

you're getting a new (bigger?) turbo :eek:

Yep still running standard FMIC. Because of it`s posistion sandwiched between the aircon and engine radiator it is not possible to fit a bigger FMIC in the same position without moving the aircon and engine radiator plus moving all the pipes and electics etc which would be a very major job. Forge do a Twincooler but at

Mate, have you thought about putting in a second OEM SMIC? All it would need is some silicone hosing and a little plumbing?? I read somewhere that doing that in parallel is more effective than one after the other...

it's a 2.5L I5 turbo, and the graph isn't really a whole lot more than slightly smoothed, superchips version (with a slightly different scale):

This wasn't meant as a petrol vs diesel thing, just what IMO is a nice looking graph

Air to air intercoolers need air to work which is why FMIC are always the best opion for this tyrpe of intercooler. SMIC do`nt get much air flow so are not a lot of use. I might get a charge cooler fitted but at the moment i don`t see the point and it is going to custom made ( exspensive ) again which i have enough custom made stuff going on my car as it is.

Yep bigger turbo hopefully will get fitted in three to four months and should be good for 350 bhp hopefully more like 400 bhp and that is with no NOS if the engine stays together. It is a project that has been worked on for over a year and will mean a lot of major engine work if it can be made to all work properly. Never intended to stay with a VT5 turbo as it was to small for the power i wanted.

but can a diesel engine either A)Produce enough exhaust gasses to spin a big turbo like that or B)rev high enough to actually use it?

It's all well and good having a turbo that can make 400bhp in a Diesel but if the engine can't get it turning until 7,000rpm say then its useless as diesels generally can't spin that quick without blowing themselves up.

I am not just swopping the VT5 for some big turbo which as you have rightly stated would create a laggy undriveable car. This is a whole new turbo system controlled in a totally different way then any other PD car runs. I hate to tease you but i have promised Allards not to say anything much about it as the system might not work well or be unmappable we will have to wait and see . Thats way in my last post i highlighted hopefully and if it works. Also getting a new SMF and clutch fitted,H+R anti roll bars and several other bits fitted as well.

sounds interesting:) so its a system that can give you low down response with high end power, best of luck and can't wait to see if it works or not

how about going down the route of compound charging with a super charger aswell of a turbo to give you the best of both worlds

Just what i was going to say!!!!!

Or maby twin turbo??????
