I know you guys are nutty about video, so here is one:

Note the car trying to get sideways in third on dry pavement. The van I passed was doing about 45 MPH.

This is not even full throttle or redline. I am still leary of whether or not I have the A/Fs nailed, especially at the highest loads and RPMs.

Sweet!! What is that chirping sound and the red light flashing on the dash?

The "red" light is really yellow, but the camera is not really good for video (its a still camera with an MPEG setting). That is the traction control kicking in.

The "chirping" sound is the BOV.

alphapenguin

do you have pictures of your car (turbo, inside etc)? hehe and maybe some of the pom too?

PS - Needs blower whine Call me jealous, but I just can't wait to get ours on the road.

mmm blower whine.... like a ufo... drool, will it have that chirping sound too :p

I like blower wine. I can't say that about blow off valves. Anyway, since I strayed slightly from topic, I'll attempt to get her back on course...

Jeff,

How many injectors did you say you are you now running, in total?

Cheers,
Hymee.

Sounds really good Jeff.. A lot better than the lens clap hitting the tripodin mine

I've had enough of "blower whine". I had a centrifugal SC on my MX-3 for a couple of years before I went turbo on that car. It was cool until you had to listen to it for hours at a time.

Still just the stock six. As it turns out, there is a lot more fuel available than I was counting on. I'm still trying to get total control of the fuel delivery at the top of the RPM scale where my maps are still producing an 11:1 A/F, even with 9 PSI.


I tore the entire strap off of the camera because I couldn't figure out a way to effectively tie it out of the way. :D

Hehehe. You still have a centifugal compressor! You just changed how you spin it. Believe me, I reckon a turbo is better than a centrifugal S/C. I'm not against turbo's per se. And Phil has plenty of experience with them. Have a look at this for a turbo and a wastegate for a rotary...





Sorry, I got the impression (wrongly) from an early post of yours that you were going to more injectors. Perhaps that was the plan for when you ramp up to the higher boost levels. The data we logged with the Motec on the Renesis showed there is plenty of duty cycle still up our sleeves.

Cheers,
Hymee.

Hymee, the e-manage can control up to two additional injectors. I think that's what Jeff was getting at. So if we want to expand, we have the option

Hymee

iTrader: (1)

Yeah - cool. I extrapolated beyond control.

Cheers,
Hymee.

Hymee, How much fuel do you think there is from the stock injectors?
My bet is you have already figured out how much and ploted it onto your airflow map. Yousneekybastardyou.

So is anyong dynoing today at Altered Atmosphere? If so, when, and can I come by?

MazdaManiac

iTrader: (3)

Yes. We start at 11:00am. Probably be there at least two hours.

rotarygod

Cool! Can't wait to see the results.

Omicron

Ok, so what ARE the results??? Inquiring minds wanta know! :D

philodox

I think Jeff posted his results in the "Turbo Dyno Day" thread in the NE forum. For my results just check the 1st post of the Greddy Installed thread.

Omicron

Yeah, I saw yours, thanks... :D ... I wasn just kinda thinking Jeff would have posted it here.

Ok, so I found the thread again here. Looks like Jeff got 225 WHP but needs some more tuning, while Jon got 240 WHP. Says a lot for what a good job Greddy did with this kit.

Icemastr

If having three forced induction cars, especially ones where you did the work yourself makes you a turbo king, I must be a turbo ruler of the universe lol. Congrats Mazdamaniac hope you are happy with the results so far.

Well, three at one time. I've turbo'ed every car I've owned for the last two decades.
This will be the 9th or 10th car (IIRC) for which I have built a custom system, not all of which were my own cars.
Going to build a turbo go-cart in the spring...

RX-Nut

Why Ice, what ya got? I can grant you the title if you show me worthiness. :p

I heard he pimps in style on a very nice Dodge Caravan (or similar)....

hey , i may be comming in late this time but i didnt see any pic of the wiring on jeffs or johns cars(i cant keep you guys straight anymore) is emanage and the greddy kit purely plug in or do you have to splice a million things? also how difficult was it to rewire like this for you maniac?
