A dyno graph means nothing and dyno results mean little in the overall scheme of things, you can see a 30WHP difference from one dyno to another.

 

we see 25 kw worth of difference here.....

Dyno run is just a baseline, tbh i think a properly scaled MAF log (g/s) provides far better input then the different dynos. But its up to the owners not to scale too much

 

So thinking about cooling again.

Main issue with the AT is the lack of choice of radiators, as the AT one has the ATF cooler built into it.

I did originally purchase the BHR one and thought i was done, but alas that was not meant to be.

So im thinking of getting the Mazmart MT radiator and mounting a seperate ATF cooler somewhere else.

Problem is where...... and what......

My front grill is already that busy, with a secondary radiator for the W2A IC, a oil cooler for rotrex charger, condenser and radiator. I just cant see fitting it anywhere in there.... However i did see Highspeed with his ATF cooler mounted on his condenser, wouldnt that create even more temps onto radiator?

I do have a rx8performance undertray (no coolers) lying around the house, maybe i use that tray? and mount the ATF on the bottom? But without a fan in place i cant see it getting sufficient airflow, and with a fan a pull setup is just going to push more hot air onto the radiator, whilst a push setup might pull cool air away from the radiator?

Decisions Decisions, anyone got any input here?

Also the easier one, what ATF cooler would i need?

 

What happened with the BHR rad? I have one but i haven't had it on long enough to see any difference. Did you also add a second oil cooler?

 

Dont really want to get into the details but the BHR one developed a leak that was not repairable. I do have the OEM factory 2nd Oil Cooler

 

Congradulations Tofo Box. My dyno was the best recorded for a long time......Now you hold that honor.

Kane just left Las Vegas and did a top job tuning mine but we did not have time to put it on a dyno. Feels stronger but without the dyno it is just my butt feeling.

 

Hey Phil! Long time no see, hope things are well! Glad to hear about your car, hopefully one of us can break that 300hp barrier soon.

Gotta ask but, what radiator are you using? are u using a seperate ATF cooler?

 

By now you know my cooling system is near the same as yours.........I think that the only difference is the Pettit added cooler.

 

Thanks for all the info phil!

Anyways onto next topic, looking into a water injection system pre supercharger to help with IAT before the charger.

Brettus forwarded me this awesome link Where Do I Position My Water Injection Nozzles

It seems that by cooling precharger it should have a dramatic effect on compressed on,

Also quote " Impeller erosion is highly unlikely with centrifugal supercharger as they spin at a considerably slower speed then turbochargers. Impeller erosion is of little concern with centrifugal superchargers. "

Prob going to use the washer bottle as the tank, may even use window washer solution as the mixture, gonna see how it goes.

Did abit more shopping for the car too recently
Got myself the Autoexe steering wheel/gear ****, should complement the black and red stitching on the Bride ERGO II seat i have, Recored the BHR radiator to go back in, Autoshineproject FEED style front bumper and a genuine RE-Am Hood.

Still looking into a AUX ATF cooler, Davis Craig is a very popular brand of ATF Oil cooler manufacturer located not too far from where i live.

The suggested ATF cooler that can operate as a standalone with sufficient cooling ability to delete the radiator ATF cooler has been pointed out as this following one

HYDRA-COOL UNIVERSAL 8 cyl TRANMISSION COOLER - PART No: 678

Will see how the recored BHR radiator works out, if it is still overheating i may need to look at the Ron Davis race radiator with a seperate ATF cooler. Just cant find the room for a aux radiator.

 

That is the exact same ATF cooler i use. Ok, not the exact brand, but the same construction, demensions, and its black. Seems to cool well under "high load" conditions. I forgot what temps i saw before removing the guages.

the ATF cooler was mounted where the right side oil cooler would be, but it was moved behind the IC. Was thinking of mounting a 2nd coolant radiator in the oil cooler spot, just haven't made time for it yet.

 

Using the torque app + a bluetooth OBD II reader at the moment, seems i am able to pull Transmission Temp and Cat Bank 1 Temps.

 

Getting the AEM water/meth fail safe system which includes a gauge.

Need to replace a gauge to make room for it, (already have 5 cant take anymore haha)

Which one of the following would you say to remove

Water Temp
Oil Temp
Oil Pressure

My water temp sensor is located on the return hose from the radiator (the one that is right under the ECU box) and it reads about 10c degrees lower then the obd reading, but the oil temp sensor follows the heater hose water temp sensor very closely.

On the other hand my oil pressure gauge doesnt even work.... haha

So yea interested to hear you guy's opinion

p.s i do have a scangauge connected as well that shows OBD water temp reading

 

I'd say get rid of oil pressure

 

thats what i am thinking too, but since i already have a OBD water temp there, wondering the necessity of doubling up.... shot a email to racing beat to see their opinion since i have their gauge pod, hopefully can hear back.

Whilst there is no other sensor for oil pressure other then "good to go/ new engine time" But i guess by the time i register it from the other external sensor it will be too late anyways?

 

On other news got the autoexe steering wheel and the AT shifter ****.

Turned out to match the Bride ERGO II seats very well, love the red stitching and feels sooooo nice to drive, with the flat section at the bottom.

 

Oh my god the steering wheel is on the wrong side

 

damn, i thought it looked wrong from the instructions!

 

Passed 40,000 kms on new motor, always had Amsoil 2 stroke fed through SOHN, always had supercharger.

No decarb.

Thought i give it a compression tests after the few pings/det i gotten during tuning

Pretty Happy with the results

@250rpm
Rotor 1: 123.35, 124.45, 126.83
Rotor 2: 126.34, 121.4, 130.07

 

Nice. I love my Autoexe steering wheel.

 

yea feels real good, still feel all happy when i reach the bottom of the wheel to turn and its flat there ^^

 

I guess I would say if you've got coolant temp through the scan gauge then get rid of that one. That's what I have.

 

yea, thats what i was thinking too.

But even then racing beat suggested removing oil pressure since they consider it not very important.

The factory OBD is reported by them also to have the most accurate measurement.

I wonder if it might be a better idea to remove both oil pressure and water temp,
Run, AEM W/M Failsafe Gauge, Oil Temp and maybe fuel pressure....

I do have a fuel pressure gauge already inside the engine bay, which i used during engine dyno and trouble shooting. Wondering if it will be ideal to change that mechanical one to a electrical one to inside the car.

 

The main reason I have oil pressure is I occasionally use my car for track days, and it was recommended to me to have an oil pressure gauge for that. If you aren't going to do track days, then I probably wouldn't worry about it either.

That said, I've never had a problem with oil pressure on track (knock on wood But I'm not the world's best driver, and I run street tires. I could see it being more of a potential problem if you were running R-compounds.

 

By the time you realize you have no oil pressure your engine is toast, an oil pressure gauge is largely unnecessary. A fuel pressure gauge with alarms on the other hand, is very important.

 

I agree . For FI fuel pressure is extremely important.

For oil : We have a sender unit and gauge of sorts already to cover off for a total calamity .
I have often wondered what happens if we lose oil pressure - it seems like it would be a good idea for the ECU to put the engine into limp mode . Anyone ever seen what actually happens with the stock setup when pressure is lost ?
