Didn't someone on here pull 430rwhp out of the 35r at 15psi or so... Nocab I think... So wouldn't it be possible to see 450rwhp @ 15psi outta the 40rs...

Zach... thanks for the pics your engine bay is very nice.

Can you send the pics of the TPS and CAT(Crank Angle Trigger) as well... And do you take paypal

Thanks for posting your dyno. And not bad for tunning yourself... I would probably blow my engine up...

 

e-mail be the graphs at ddearborn@spymac.com
I'll host them for you.

 

Running a almost identically sized T78 with a 40R comp wheel Jason put down a little over 500 at 20lbs, that is a different dyno and people have questioned the way he chose to calibrate it, but that's their opinion, and even if it was off by say 10% it would equal right around the 460 number as well. I figured the turbo should be good for the upper range of 400whp@around 20psi it does seem to drop of a little up top, I'm sure a little fiddling here and there will net some increases. 367whp@12psi is not too shaby

 

It sounds like you took the words right out of Dave at KDR's mouth. He showed me other dyno runs for comparisons.

 

Wargasm is going to host the sheet and my timing map. You'll see my timing on a goofed up spreadsheet. Air fuel ratios are on the bottom of the dyno sheet.

I know giving this information away is like handing your girlfriend to your buddy to have, but hey, since I tuned myself I would like to have some input from you guys.

 

Just so it's clear I'm not bashing Jason or his dyno, just more or less agreeing with Rice it should be closer to the 460 mark.

 

Nor was I. We did not even talk about any numbers other than what he had on his dyno PC.

 

nah I wasn't thinking you were when I went back to reread the thread and see what you posted I figured it could be taken that way, I was just merely saying the two would be around where rice was saying and that's all, my feelings on dyno's are simple as long as they are calibrated correctly and settings are correct, what you pull is what you get. All this needs to be corrected for this altitude or this state is garbage to me, I know the why and I know the how, where my problem with it is simple I live up in denver and pull X# but corrected it would be Y#, the problem is I don't live where Y is, and maybe just maybe on Tuesday Z is a 110degress. So if I lived there my car is dynoing less also on that day, and truth of it is I will be making less on that day.

 

I did 430 at 16 and 470 at 20 when I had my 35/40

 

I have had many cars on my dyno (Mustang) that have since dynoed on a dynojet and put down very similar numbers, so I know its close.
With that said, Zkellers numbers are way off. I would agree with RICE RACING and say that you have alot of timing pulled out or its running to rich.

RSE... those are some impressive numbers... I just hope that the 40R kit can pull something like that.

It should be possible.

 

As soon as Wargasm gets the sheet and the timing map up, fire away. By the way, the air fuel readings on the dyno matched my meter in the car.

 

Rice Racing. You looked at my timing maps, remember?

 

Where in PA are you?

Jason

 

Here are the dyno and the ignition timing....

Looking at the timing at 15 psi (load 200 row), it looks fairly reasonable to me. I run even less timing than that...

Based on the info I have from the dyno sheet, I think that maybe something is pulling a lot of timing. Do you have a log of the actual timing used during the run?

Sorry, I remember now, there is nothing in your timing map that would cause such a big difference in measured power with those boost increments.

Just need to nail down if the 360 odd rwhp was an "freak" reading @ 12psi to get a relationship of the other figures. If there is a trend there then it seems like there is some restriction going on somwhere that is not giving yo a linear rise with increasing boost pressure ??

I would not use any more timing at 230kpa even on 100 !

 

Your .dat file shows 9.5 deg timing at full load ? Thats a little low for 100oct with that split.

 

Must hear more. keep it coming.
kris

 

preety good results

 

Oh yea, I forgot to tell you. Add 8.5 degrees to the timing on the dat file across the board. Autronics does not have a gain adjustment like Haltech and the 3rd gen has a fixed trigger. In order to get the timing zeroed out I had to negate the timing 8.5 degrees in the barametric pressure correction settings. In other words, the dat files may say 10 degrees when in reality the engine is at 18.5.

Now the timing values in the CAL file are what the engine is seeing.

Make sense?

 

I am in York. York is located about 50 miles North of Baltimore, Maryland.

 

Timing looks solid through the run. I did notice on the air fuel readings that at 6500 I dip to 11.18:1 just for exactly 2 seconds, then it's back to the mid 11's. That should not cause any major problems.

 

Steve, Autotune is not yet available on the rotary chip set, but is on it's way. It has what they call manual tune which works very well. You pull up a datalog in a micture table and it tells you which cells need corrected, hit enter twice, and they are corrected. Same principal as Autotune, just not on the fly.

 

Total, thanks

I cant see any tuning fault/s you must have some other mechanical restriction in the system, be it, turbo, IC, Exhaust etc etc.

Charge temp looks good, timing is good, mixture is good..... job well done
