Post Your Single Turbo Dyno Sheet...
We all know the single turbo set-ups from the original post from: https://www.rx7club.com/forum/showth...threadid=33502
Now it's time to see the proof! I'm not here to doubt you guys, but I or shall I say, we like to see it on paper. Thanks.

Here's mine w/ a 60-1 HIFI on a not-so-traditionally ported 13B:

Dyno stopped at ~7600rpm. Should've stayed in it.

Car: 93 base
Turbo: IHI RX6 (A'PEXi kit)
Boost: 13 psi (15 when I get the boost controller installed)
Manifold: A'PEXi tubular stainless
Wastegate: A'PEXi Racing (??mm)
RWHP: 367RWHP @ 13psi (Dynojet, expect 400 @ 15 psi)
EMS: A'PEXi PowerFC (XS tuned)
My dyno charts are here:

My new setup (not yet on the dyno) will be:
Car: 93 base
Turbo: IHI RX6 (A'PEXi kit)
Boost: 15 psi w/AVC-R
Manifold: A'PEXi tubular stainless
Wastegate: HKS S/S Racing
RWHP: expect 400+ @ 15 psi
EMS: A'PEXi PowerFC (XS tuned)

Nice numbers there!!! What fuel did you make that power on a 60-1 hifi? What trim is the turbine wheel?

The turbocharger is a 60-1 HIFI with a 0.60 A/R cover, standard TO4B CHRA, and a tangential P-Trim turbine, undivided, 0.96 A/R ratio housing. I was running between 13 and 17psig of boost (WG and boost controller problem at the time).
Dyno cut short at 7600rpm in 3rd gear. I should've gone higher.

I like the idea of this thread, perhaps a sticky on this would be in order, to go along with the setup thread. I will print some graphs out next time I am at the shop.
I would suggest recommending some guidlines to make the data more comparable. For example try to post graphs that were done in let's say fourth gear, use SAE corrections, and start recording at say 2500 rpm so we can get a better idea on how each trubo setup spools. I would also like to see HP and Torque curves with RPM across the bottom.
This is just a suggestion posting anthing is better than nothing but if possible conssitent data points will make comparisons much easier. Oh and show as many boost levels as you can. I have curves I can show with my car everything the same, one with a T78 and another with a T60-1, at 15 PSI the curves are almost identcal except the T-60 spools about 500RPM sooner, I will try to get these up ASAP.

Ok here is a comparison of a T78 and a T60-1, same car, same manifold and everything just different turbos. For some reason I could not get the graph lines to print out but you get the idea. You can see the T60-1 spools a good 500RPM sooner and at this boost level does not have a significant HP difference. Unfortunately these runs were done in third gear so they are down slightly in power. It may also appear that the T78 had a late start but the next post shows the T78 starting at 3K in fourth gear, only the recording was delayed I floored it at 3k on both runs. All runs are straight pump gas and boost is maximum value seen on data log, as you can see the boost droped slightly at higher RPM.

Here you see the T60-1 spools to max boost 10PSI a little under 3500RPM and 12PSI just under 4000RPM. These runs were done with a noise reducing 2" restrictor in the exhaust. I lose aproximately 10 and 15 HP respectively at these boost levels. The higher the boost the more power you lose with exhaust restrictions.

Ok last one, here is the T60-1 running 10PSI with restrictor compared to a sllightly modified stock sequntial FD. As you can see the stock sequntial spools so dam fast, even though it started later it still hit full boost sooner, just look at how fast that torque curve shoots up. From what I remember nonsequntial stock turbos spool much slower, maybe even slower than the T60-1. I don't have a dyno chart from when I was stock nonsequntial, would anyone like to share?

Hi Tony,
I know the low end response and spool time of stock sequential turbo is awsome. If only we could make big power with this kind of response. Gee, I could of had a V8, right Jim?

How about I just add a section to the photo gallery for dyno sheets? You can upload the images and all the details of the run there. Same result, but no clutter that we get from all the stickies up top.
