Buschur Racing dyno thread.....new developments.
I want to try the i/c pipes and mas pipe next. Then maybe the intercooler since the front fascia is off anyway. I don't want to go to far as it will have to be put back to where it is now for the flash work we need to do.
I will continue through the stages though and I am trying to be very open about how it all goes, as you guys can see from the above.
I plugged in an EMS right out of the box tonight and left the factory mas and such in. I hit it real quick and could hear a difference. I forgot to hit the record button on the dyno. I am very anxious to get back to this next week. I had to call AEM with some questions regarding running the car with the factory mas in place, as we always have converted them to speed density in the past. I am ready to go next week.
I am hoping I can offer the EMS with no sensors and no wideband as a drop in and run package after all of this tuning.

What is very interesting for me is that 95% of the post tuned stock evos make within 10 whp of each other - usually between 255 - 260 on bone stock evos with the flash. Obviously proper tuning and adjustment to match the individual car is some what of a leveling influence on the power outputs.

Good work David.

Good work David.
Good work David.
With a custom tune from me, it would yield a lot more power as I would be able to run it leaner and with more timing without knock
In the case of that customer I will never know - but his car was able to run 2 more degrees of timing than most stock evos on 93 octane
At the time, it was when my experience with evos was more limited, however, I still have his maps and dyno sheet and looking at it today I am convinced he was running 100 octane fuel
Al, you can PM me this info, but what timing was he running? I have one of those "ringer" cars too that seemed to be more powerful than others.. I was able to tune as aggressive as 22 degrees at high RPM and run fairly lean without knock.. about 5-7 degrees at peak boost.. And this was on 94 octane.. so its not unheard of, but definitely unusual.. though it also could be a "Numb" knock sensor.. Don't reply to this post, PM me or start a new thread if you want.. I don't want to ruin this thread..
Im very curious to see what power can be picked up from the intercooler pipes and MAF pipe. I know there are many people in the same boat as me. I cant wait for the dyno numbers.

In any case, this thread is exactly what I need to know about parts. Actual data consisting of facts and numbers. The more I read about Buschur Racing the more impressed I am. I wonder if any of the JDM manufacturers put up their numbers so candidly. Truth be told I'd rather buy parts with test data available to the general public than some mystical overseas magic part. The only thing to make this better would be a tuner face-off. Get the east coast guys vs. the west coast guys vs. the red states on the same dyno hardware on the same day on the same gas. Break down the results by price, whatever you can get on the car for under $1000, $2000, $5000, etc..
Cheers David, fight the good fight and you'll have customers coming back again and again.

We did this... "Dyno" was Streets of Willow Springs Race Track ;-) . This track pays a premiun on midrange grunt and usable power.
Top 8 cars all had suspension setups by John Mueller at RRE
1st BR500
4th BR Stage IV with BR AFC tuning (through the mail)
Note this "Shootout" had 12 "Big" turbo cars getting their cans kicked in...
Dynos are good to use just like David is doing here. You get a baseline and build your monster testing as you go.
Sorry David back to topic

I then put the offroad pipe in and was expecting a ton. Well guess what folks?! The gain isn't worth pulling the factory cat out for and risking running without it. From what I can tell by laying quite a few runs over each other you might be talking about, at best, and only in parts of the runs 7 whp. Peak power was completely unchanged. Very-very good stock cat on the car from what this is telling me.
perhaps you will still see that 7whp gain and meet emisions !

The settings come with our AFC's when they are bought from us. To be honest if the parts that are on your car are not from us then the settings I supply for our parts is only going to get you close. We do give the settings away on occasion if you have bought the rest of your parts from us.
Great job at the last event Robi!! Love seeing that car kick butt on the road courses! I also like to see the other guys that talk the talk but can't walk the walk not even show up to compete!

You know, sometimes I get my best ideas at night. This really sucks for me as I don't usually sleep well. As a side note I have taken up drinking some wine before I go to bed and this seems to help
So, last night I am laying in bed sleeping well. Dreaming of the dyno, really, this is how my messed up brain works. Then all of a sudden, since I am asleep and not being bothered by 10 people at once, I get this freaking thought. Why the hell did the car pick up 15 whp with an axle back and not gain anything from the cat and downpipe?! Then my mind, while talking to itself in this dream answers back, "The cat back pipe dumbass." At this point I wake up and walk to the kitchen to get a note pad. Write myself a note, "Get rid of the catback pipe with the two restrictive resonators in it dumbass."
I spend tons of time talking about how to build a correct exhaust for a car. Straight through, no resonators, no baffles, always go from a smaller tube to a larger, never the other way. Here I am picking up great gains with an axle back and non with something in front of it. The cat back pipe while not too bad (I thought) still has only 2.25" diameter and also has two resonators in it which is what keeps it quiet.
Monday morning I am going to drop the exhaust at the back of the offroad pipe for another dyno run on the AFC. I think the problem with no additional power being made is from the catback pipe.
Now I won't be able to sleep tonight, I have to know......
