Brisbane Dyno Day

[twilightprotege]

Hi, sorry for the late notice but I only just remembered (coz i PM'd JEB83 about it - thanks bud) that Mercury Motorsports (www.mercurymotorsport.com.au) is having a pre-opening dyno weekend this weekend coming up. Cost is $45. They are located at newmarket rd, newmarket

If I can get some quick replies - by say thursday at the latest - i'll try my hardest to get all us Mazda ppl dyno'd around the same time. I'm going to be running my car for sure.

so let me know - email me at katsuro@tpg.com.au so i can book us in.

yeah that was a great run kurt! i'd be very happy with your run!

Hey there....
Nice power run Snert, what are the mods done to yours??
Need to get it out to the track and have sum runs.

Did you have a dyno run Twilight???

All is looking good for my bro's 808 wagon for the Jamboree in a months time. Ran 11.51 with a best of 117.4 MPH into those very strong winds on the weekend, should have a little still left in her.

Don't think wagons can launch? How does a 1.46 sec 60ft time sound?? Slicks are working great

i actually got less than kurt - 93.2 is the printed run on mercury motorsport :

the graphs are very interesting though. my engine is running richer and it's quite obvious my intake cam is too big. if our cars both reved higher i would have taken over kurt's power figure, but because of us both being 6500rpm rev limit, he wins!

damn good 60ft time! next time i go drag racing (hoping my clutch doesnt die) i'll be aiming for flat 2.1 sec 60ft. when i get more power i'd like to get under 2 seconds. would be a fantastic time for a fwd NA car!

and yeah i keep on telling kurt to take his car drag racing. oh an he has an injen CAI, awr header and 2.25' mandrel exhaust with the same cat, 2 resonators and muffler as me.

Yeppers, u need another 1000rpm+ to make good use of the cams
Both cars are running a little rich.
Will keep u updated when the microtech is installed in friends car, apparently the sensors and ignition stuff is similar to a 626 turbo, but when put in the car, there is obviously something different with the SP20 engines (as u might expect with an engine thats a lot newer/advanced). So its gone back to microtech... hope its back soon.

perhaps you should put an air restrictor in place???

 

[twilightprotege]

yeah easily another 1000rpm....but instead of that i'm going to get the intake cam made smaller (not by a huge amount through). according to dyno2003, the intake cam i am getting will create more power everywhere compaired to the one i have up until about 7600rpm, so even if i do raise the rev limit in the future, it'll still be singing

james, if only it was that easy. the ecu is smart (or stupid) enough to realise this and just pulls fuel as well to keep the same farked up a/f ratio

 

[ahb11m]

i meant infront of the maf

block the screen off

 

[twilightprotege]

it would still know.

however, a backyard way to fix it is to have after the maf another air intake spot. that way the MAF will think you're getting less air than what you really are (because of the bypassed air) and therefore give less. the problem here is not knowing how much air you're getting, and how to control it.

i have an idea. on the CAI where the pipe from the valve cover goes to. i could take that pipe off. it's only a 5mm opening. probably wont do much, but might be good for a few point on the a/f ratio! would prefer to install my a/f ratio before doing this or do this on a dyno

essentially this what a piggyback ecu does, but properly. still allows all the air to flow through the maf, it just pulls fuel where required to up the a/f ratio to around 12.5 (good figure for engines)

 

[ahb11m]

you could just give it the air it wants... and we all know how to do that :d

 

[twilightprotege]

open the bonnet???

 

[ahb11m]

*cough* forced induction *cough*

damn i need some sudafed for this cough.... what was i saying?
oh who knows....

 

[twilightprotege]

yes i know i know.

found out from one of the very knowledgeable guys on the board, installshield 2, that adding more air than what the MAF thinks will probably do nothing. see : http://www.msprotege.com/forum/showpost.php?p=1164455
