OK whiny biotches. I'll log a 4th gear. Sheesh, just cause I'm really an ignorant newb that doesn't know that 4th is 1.1 or even noticed that was asked for...

Do you really think that my pull up a 12% grade with the AC on, a passenger and a trunk full of phone books was what helped?!? LOL

My car is pig heavy though. C package with hard and soft top + my 200lbs of "added lightness"!


EDIT- OK made 3 4th gear pull see my earlier post to compare 4th to 5th. Lost 100-200 rpms of spool low to high. Happy now? I'm friggin depressed...

Actually I'm still in the cluster of 2554's and 2560's, just at the high end of it vs. the middle. Still a happy boy!

1psi = 1863
2psi = 2060
3psi = 2225
4psi = 2456
5psi = 2549
6psi = 2733
7psi = 2880
8psi = 2990
9psi = 3090
10psi = 3190
11ps = 3250

I was curious about the effect of gear selection on spool so I logged some pulls at lunch today in 2nd through 5th gear. All were started from ~2000 RPM with very light throttle (constant speed) before WOT.

I expected to see slower build in lower gears of course, but the effect is more than I thought it would be. Here is the resulting graph submitted for your consideration. I have added trend lines since the 5th and 4th gear data are noisy. The trend is pretty clear, especially in the lower gears.

So the point is, everyone needs to do this in the same gear ratio because otherwise the data is noticeably skewed. And no power braking either :giggle:

I updated my original post on page 1 with a pull starting at 2000 rpms.

So I have a proposition based on Paul's comment regarding pulls starting at low RPMs not reflecting a real-world pull. These tests are more a measure of at what RPM a turbo begins building boost at. And the trend as expected shows that in general that smaller turbos build boost at lower RPMs.

So what about a scenario that is more real-world? What if we try some spooling runs where we go from steady state RPM (speed) to WOT starting at a higher RPM that would be more typical of what one would do while driving? This would show how well the turbo responds. It looks like most everyone is making good boost by 3500 RPM so I think that is a good starting point.

If we really want to make it interesting, we could throw time into the equation and plot on three axes. I'll do the plotting. The MS logs at roughly 10th sec intervals so the spool should be able to be caught. Adding time would show some things like additional power (more power means faster RPM build up), and differences in differential gearing.

So I'll throw this out there. Format:

Mods feel free to start another thread if you think this is getting too far off the mark. AND, please use space delimited text, no equals signs or units in the actual log data. This makes it easier to import into Excel.

just do a pull from 2K in your 1:1 gear on a flat road. the end. better yet. all you suckers strap on a dynojet with boost logging, we'll directly compare our runs vs torque output.

Yeah, I don't think you'd get much more from redoing this. Power curves (tq/hp) would draw a complete picture of the setup.

Well we already did that right? I'm talking about taking it a step farther. Of course if no one else is interested... :dunno:

I do not have any dyno run data, at least not yet... But I agree that would be a great thing to look at. This shows the small turbos spool sooner, but it would be good to see how much less power they make once they achieve boost. Wouldn't everyone need to do pulls at the same target boost level though for that to work? And use the same type of dyno at uncorrected RWHP?

Yeah, It's like Tim's new twin turbo setup might spool later than mine, but our torque output below 3K was nearly identical.

Sam thing with me and Samnavy's setup. He has a T25 that spools faster than my T3, yet I'm making more torque throughout with less boost.

http://www.boostedmiata.com/dynos/sc...with_boost.jpg

If i'm cruising at 3500 and mash the gas in either of my cars high boost is pretty instantaneous

+ 1 for Pauls comment. When I hit full throttle at mid to high rpms it's less than 1 second according to MS logs to full boost. It would be hard to find real world significance between a spool of .74 and .92 seconds even though statistically it's 20%. Functionally I think it's pretty irrelevant.

Yes- it would require similar steps for power runs BUT regardless it would further illustrate the efficiency of the system. It would illustrate what you get for the boost at any given point. It would be a good reference for somebody building a turbo Miata IMO.

OK agreed. I ran a log today on the way home going from cruise to WOT at 3500 and boost was pretty instantaneous, faster than I would have guessed.

Agreed on the value of the HP plots for the different setups. I have looked at many of the past plots to see what I can expect at X boost with turbo A. Very helpful. And, now that we have this great spool comparison plot we can compare spool times for Turbo A versus Turbo B as well, to assess 'streetability' for example.

But it would still be nice to compare torque or power levels, but correct or normalize them somehow for the different boost levels. That would make a comparison of two different turbo sizes comparable even if they are not running at the same PSI. So, what about something like a plot of torque per psia (not psig AKA boost) at a function of RPM? So, for example, take two Miatas: Car #1 with a 'big' turbo, Car #2 with a 'small' turbo
Car #1 at 9 psi of boost (24 psia) is making 210 ft/lb torque at 4000 RPM
Car #2 at 12 psi of boost (27 psia) is making 220 ft/lb of torque at 4000 rpm.
Therefore Car #1 is making 210/24 = 8.75 ft/lb per psia
and Car #2 is making 220/27 = 8.14 ft/lb per psia

So it shows that even though Car #2 is making more torque, when corrected as shown above to torque per psia, one can see the efficiency advantage of the bigger turbo. It is making roughly 7% more torque per psia. It is not exactly a perfect comparison but at least it normalizes the data a bit. Maybe a correction factor for 1.6L versus 1.8L could be thrown in as well. This is just at one datapoint of course. The normalized data could be plotted over the RPM range.

OK not trying to be difficult here, just throwing it out there for consideration.

I sure would like to see spool data for a 2554 on the current FMII manifold. Guess that isn't likely to happen on this forum.

+93432343243e33

I was thinking the same thing when I first opened this thread. It would be "neat" to be able to see the difference between a 2554 and a 2560 for example, rather than "just get the 2560, more power, spool's bout' the same".

Here.
Ignore the ringing.
The extra boost up top was from a change in the boost map.

Was it colder out?

I think the first log was cooler by about 10-15 degrees. 70 degree ambient temps today when I took that.

still needs some tweaking but this is the result from tuning ebc tonight with ambient temps of 65F. So far I like it much more than the gt2860rs. Much more torque much earlier.

anybody that has aem ems please post datalogger of dyno pulls!!! maybe then I start beliving these magical numbers.

WOW I just PM Deerhunter on M-net about his 3071R stroker. His response was a link on a discussion here.

Deerhunter
"I'm at approximately 2,000 ft above sea level. The difference in spool is very apparent compared to Grand Junction (4,500 ft+). I'll do a datalog as soon as possible, but here is my recollection (based on gauge pressure):
5 psi at a tick past 2K
10 psi before 3K
20+ psi before 4K

Seat of the pants feel is VERY nice I wonder what it'll do at sea level?

BTW, I'm using a DEFI boost gauge, so I'm going to assume that it's fairly accurate.

Once EBC is hooked up and tuned I expect to hit boost target by around 3200 RPM.

Posted this spool info in another thread so thought I'd copy it here.

Engine: 2L FM stroker. 8.8:1CR
Turbo: Custom GT3076R (mix of 3071 and 3076 with larger internal wastegate)
Manifold: End of the line BEGI FM

Headwork: 1mm FM supertech over sized valves, FM valve spring kit and extensive headwork (see details in website link below)

Other Spoolin' Helpers/Hurters: Blitz SBC i-D2 boost controller.

Trans & Rear End Ratio: 5-speed, 4.1 LSD
Rear tire size: 205-45-16's

5th gear pull
120kPa = 2150rpm
140kPa = 2600rpm
160kPa = 3050rpm
180kPa = 3350rpm
After 180kPa boost rises more quickly.

FWIW I preferred the GT2860RS on this motor at my favoured power range of 320 to 340bhp. I'm too much of a wuss to push the current turbo :giggle:

So I did a 4th gear pull on the way home to get a log for the GT2871. Here is what I came up with (see the graph). Not bad for a big turbo, not far behind the GT2560 setup I had before. Plus it was hot outside, like 95 deg F.

I have not yet hooked up my EBC :) Also I will be installing a new motor to run around 20psi, and a new compressor wheel on my T3 that is basically a 48trim 2871R wheel.
