If some of you remember this thread: https://www.miataturbo.net/forum/sho...ighlight=spool

we started collecting spool-up rates of various turbo setups and threw them into a chart.


I would like to collect new data and try again.

So please respond using the follow example:

Engine: '93 1/6L
Turbo: T3 Super 60 .48 A/R
Manifold: BEGi Cast "Directed Pulse"
Downpipe Size/Style: Single tube 2.5" to 2.75"
Exhaust Size: 2.75" to 3"
Exhaust Components: Louvered resonator & Magnaflow Muffler
Intercooler Core Size: 18"x12"x3"
Intake Manifold: Stock
Headwork: Mild Porting, deshrouding, blended bowl
Engine Management: Megasquirt
Other Spoolin' Helpers/Hurters: Toyota COPs
Trans & Rear End Ratio: 5-speed, 4.1 LSD
Rear tire size: 205/45-16

FOURTH GEAR PULL:

RPM Boost(psi)
2250 1.88
2300 2.46
2400 2.9
2500 3.48
2600 3.77
2700 4.5
2800 5.65
2900 6
3000 7.25
3100 8.1

3300 10.7
3400 11.75
3500 12.2
3600 13.5
3700 14



Leave it on topic, or posts will get deleted. Try to take the log in 4th gear to keep things constant, and start the pull from 2K. Have fun, don't need to keep pulling to 7K and go +100mph

Plot for those posted so far

ZX-Tex

iTrader: (15)

OK the new and improved graph is posted above. The xls file is attached to this post so if you want to change the plot or add your data, go for it.

Cueball's boost slope is nuts! Pipefathers is pretty steep too.

It is also interesting that Brain and TurboTim took two completely different approaches and ended up with practically identical spool behavior.

JasonC no offense but are you sure about your numbers? Our setups are pretty similar but yours is spooling 500 rpm sooner with a clogged cat?

Of course the other factor here is efficiency and how that translates into power. It would be interesting to see a 3-D plot with power added as a third axis.

rear tire size at that time was 215/45/15.

That was when i was just learning how to use the EBC and my chart was as follows. The 2nd one is what I run now. I should go do a log just for the **** of it.
