Been at 1320 autos today and here is what was planned:

1.Dyno car as it is (15% pulley,RMW head,1320 cam,Janspeed mani+cat,GP I/C)

2.Dyno the car again with an oil change (using a special oil same grade as OEM though)

3.Then get Jan(RMW) to tune it and then re-dyno

1. dyno-248BHP (car as it is without tune and with 380cc injectors)( 215-217WHP)

2. dyno-251.7BHP (special oil used) (220WHP)

3. The kind guys at BMW when they flashed my ECU with the JCW map somehow encrypted the file and it was not possible to alter the map (map file is currently with Dimsport in Italy to see it they can get into it, should be sorted by Saturday and then it can be mapped)


I also tried a GRS intercooler to see the gains over the GP intercooler and and it made 254BHP so it show a gain of 6BHP

I got an odd reading with the torque curve when trying different combos though:
(When swapping the oil and the IC though they both seemed to follow a similar pattern on the curve i.e making more peak power but anomalous torque curve)

OEM oil and GP I/C- peak lbs/ft=201 (248bhp)
Special oil and GP I/C peak lbs/ft=197(251.7bhp)
OEM oil and GRS I/C peak lbs/ft =200 (254bhp)

The special oil was also making more power over OEM oil but the oil temp didn't rise. Would like to test this on track to see how the oil temps compare. I would expect the oil temps not to rise as much as OEM


At one point though when we were waiting for the oil temp to get to the correct temp the dyno fan was running and must of cooled the I/C very well as the first run I seen 235WHP(266BHP)

Just need to get it mapped now and see what power that can gain

Will post graphs when go on desktop comp so I can scan them

But for now I'm at 220WHP

A very impressive power figure there Jaw_F430 , congratulations .

So whats this special oil you speak of .

[GRSmotorsport]

Great result!! I remember you talking to me last weekend about using some different oil, sounds interesting.

Bet you're really pleased?....

[quote=Hyper Active;3433336]A very impressive power figure there Jaw_F430 ,

Well I have just tested it for a company, you cannot buy it yet but it may be available soon, it is not available to the public as the company mainly does power sports but are developing an automotive range


Cheers for the positive comment

Cheers Graham, yes very please so far and still more to come!! Your air to air worked well

I am deciding whether to get a chargecooler now though seeing how important the cooler air is It is only when you see a it back to back .

[BigShow300]

And there was me ready to send round the witch hunters when you mentioned some magical oil that could increase bhp... truly amazed by both your awesome numbers and the results of the oil, top work fella!

So what spec have you got now?

[sef]

Nice work. Bet you are well pleased...

[alski]

did you log any air/fuel ratios?

[sam_a156]

You're da man! Especially that you fitted all the goodies yourself!

The figures are very well in line with what I'd expected to see based on my own results. Now I REALLY can't wait for my 1320autos cam to arrive (it seems that people have seen up to 10whp increases with the cam)

What kind of IATs you were seeing during these tests? After now owning the Scangauge for some time and observing the temps (especially that it is getting warmer) I do now believe that this is a real concern when doing dyno tests. In heavy traffic I have seen temps as high as low 60s (in C) and they stay high very long even if the car is parked somewhere (and there is ALWAYS heavy traffic here).

this is exactly why we have developed a Water to Air system that keeps the car cool and preserves that precious horsepower

Spec:

RMW head
380cc
1320 cam
janspeed mani +cat
JCW airbox
GP I/C
15%pulley
JCW map at the moment
Special oil
stock exhaust
stock everything else

Chris did log a few runs and it was running rich, but mid 12's near the redline I think

actually mid 12s is lean for this car

it should be running even richer at 11.5 -11.2 area

Maybe them figures of 12 were wrong then I can't remember, I would have to ask Chris. But he said it was rich. (the exhaust tips are very black)

Update: It was rich at first as the ecu was in limp mode as the guys at bmw didn't clear all the faults out of the ecu when they fitted the enigne but I didn't notice as I was running it in and not using above 5K ,it wouldn't rev much above here

Maybe it was just lean at 7k with the 380cc, only taking it to 6k until I can fit the 440cc

Intake air temp was at 30ish before the dyno runs and then went up past 50 as the revs risen. The GP I/C did struggle as once the temp got above 50 the timing was knocked back

I may get a chargecooler now though.

Had my scangauge plugged in today though on the way home from work and Intake temps were around 20-25 most of the time, even after a little blast the temp only went to about 38 which I think was very good. A lot more air though in the real world opposed to the dyno

this is the hard part of dynoing.....getting the proper airflow on the car or the ecu will stop you from making power

now you can see why we now have a water to air system
you will see high intake temps blasting around the track on a air to air system

Maybe we could get a group buy on the W2A?

Thats why most of the big boys swear by on the road setting up. You'll never get a dyno to give the right airflow unless its a full on wind tunnell.

at the shop we dyno at they have some pretty good fans, it's close enough that we see only about .2-.3 a/f off of what we see at the dyno when on the race track

I have the innovate wideband in the car and have tested it repeatedly against their system

this shop dyno's Bonneville record setting cars, road racing champions and dragstrip champions. Hondata uses their facility exclusively for their testing
