Nice gains Tony!

 

Is just me or the RX makes more power than the IS even though its heavier...

 

I was thinking same! I know we have to factor in FWD/ RWD drivetrain loss differences, but those results are close to stage 2 setup.

 

hmmmmm


@Tony...what kinda juice you guys are putting in this RX

 

Hi Nuke
Pump gas only and rescue the drivetrain loss so we put light weight rims also[/QUOTE]

Totally agree FWD and FWD drivetrain loss different.
We found that the intake air temperature during the test affected the pressure value.

 

One of the reasons why i do prefer the Air to Air intercooler, but the Air to Water has been said to be more efficient and cuts down 0-60mph times, plus other manufacturers have gone this route on their turbo motors as well.

I'm sure it does when the temperature is less than 80 Fahrenheit the car feels more responsive and powerful. I wanna go dyno the car in a few months ideally in november-december to see how it runs.

Hotter IAT (Intake Air Temp) = Less power

Fix- Increase intercooler water pump timing

Turbocharger/Intercooler Cooling System Heat is one of the worst enemies for a turbocharger system and precautions need to be taken to prevent the turbocharger from constantly being overheated. Lexus has developed a dedicated turbocharger and intercooler cooling system that is separate from the engine cooling system. This system has its own radiator, electric water pump and reservoir. The ECM varies the pump motor speed based on various inputs in order to achieve an optimal coolant flow rate. The turbocharger/intercooler cooling system makes sure that the system stays at the right temperatures. If the turbocharger is constantly overheated, oil coking and turbocharger bearing failure may occur. The capacity of this system is 3.1 quarts of SLLC.

 

i need me one of these setups....avrage temperature is 40c on a good day in summer here and hits 60c+ in the sun and traffic

 

There is our RX200T dyno test with stage 1 tune IAT/boost value/Ignition timing ........Automatic correction value.ve
Ignition

About Chinese word please try to use this more easier

Engine RPM......RPM
Intake temperature........degree C
Boost request value .........kpa(Absolute pressure)
Boost actual value.............kpa(Absolute pressure)
Ignition timing.............BTDC degree

41-39C


65-45C

 

so what did we learn from this practice

 

It looks like intake temperature is a huge factor. Reminds me of VW, they're very fickle. I did some dynojet runs and saw a 20 whp fluctuation between my 1st and 6th run. Initially outside temp was about 95 degrees, by the time we completed all 6 runs it was 98 degrees not to mention the heat soaked engine and intake temp. Tony is having a look at the dyno sheets now

 

Small revv video. Ppe catted downpipe, no resonators with stock mufflers

 

Oh yeah i noticed that when i went to the track when i first had the intake on and the times kept going lower i knew it was because intake temperature
