I want your spool data!
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 3200 9.57 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 ;) |

FIFTH gear data, same setup as my post #11:
2000 3 2250 5 2500 6.8 2750 8.6 2900 10 5th gear data about matches Paul's absurdflow data in the graph above, but doesn't beat PhilMD's. |

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. |
I updated my log as well...I copied from an old thread just to start the thread, I had new data to share.

I'll post Paul's to the best of my knowledge. He will let me know if I'm off here. The spool data is taken from the original thread.

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 fuck of it. |
I'll chime in with my unsorted map:
