Hey, i am really disapointed my hks t04r, with ported engine with 1600 cc injectors only made 375 fwhp! Am gutted  :confused:. I  went to dyno demon near chester. I had inlet temps of 70 degrees with a front mount intercooler. In my eyes they had the fan far to far away from the vehicle. All the way home my temps never went over 30 degrees.

Maybe the dyno was a rubbish one I have seen these portable jobbies give out dubious readings

Maybe, but it seemed a very good set up. Its a dyno dynamics rolling road.

We need more details
what boost are you running? who mapped your car?

On an old setup with a T04R at 1 BAR my car made 390rwhp which is around 460fwhp

Has it got an aftermarket ecu?  Has it been mapped by someone who knows what they are doing?  Just bolting on performance parts without having then setup on thesse cars doesn\'t work too well.

70 degree inlet temps will kill your power and your ingnition retarded due to it.  1 bhp for every degree of air temp plus your ignition makes a lot of difference.

The other thing to note is that your ecu is also not mapped to see 30 degree air inlet so wont be accurate.
400 BHP - 650 KG\'s = 616 BHP Per Ton of Rotary Power

That\'s the way to do it! :Thumbsup!

Does it really make that much difference Tony?   If so I think Water Injection has just been added to my shopping list!  

Mind you, the 70 degree temps he stated must include quite a lot of heat soak?  Actual intake temp would likely to be a lot lower I would of thought?

It is running 0.9 bar of boost, i have a apexi ecu and commander, greddy profec boost controller. It was mapped by a guy called colin at lindop motorsport.

There is some thing not right here.  For a start if a tuner knows their cars and tunning ability then the first thing will look at the ambient temps, inc air, water, oil etc.  Who would map a car on high intake temps and why?:rolleyes:  

The figures from that turbo looks very low i was expecting round 400atw from your setup Mathew:rolleyes: :yes

Just a thought, but what is the size of your exhaust housing?

no clue at all.

Even with a piddly 0,81a/r these make lots of power. I\'m sure the intake temps have a lot to do with it, but how many miles on the motor?

I think you need to take it to WGT in Cheshire matey for a remap,
any idea what afr you were getting on boost

Was it this hot while tuning, or was that done before the dyno run(s)?

Thats frankly insane, I cant remember the last time we had a car any where near that hot on our dyno - and I think we\'d struggle to get a car that warm unless it was a 90 degree day in summer and the car was running a load of boost on stock turbos and intercooler...

I can tell you we wouldnt have continued running it while it was that warm tho.

Power-wise, depending on turbine a/r, I\'d expect a solid 350+rwhp from a T04R.

As i said on FDUK,   WI,  Premix and a good tune is the answer,   obviously not having 70 degree inlet temps is key also.

i get up to 70 degreees inlet temps but that is with stock IC and sitting still for long time. cruising temps are in the high 30s which is annoying enough and in light traffic high 40s which i hate.
 
did they not have a fan on it? it should be extremely powerful and keep the temps nice and low esp with a front mount.
