hi all,

i know there was a single turbo comparison done by a few guys a while back? they compared the SP60-T78 turbos and charted them out on graphs and what not.
i'm wondering if anyone can give me a link or info on that comparison.
although it's not the most accurate to compare, it would some what help in looking into different turbo kits!
thanx~

Could whoever did this redo it with the correct sp63 dyno #s. We dynoed a car today with our new kit.... Here are the #s:

We started the pull at 4000 RPM
RPM - HP
4000 - 240
4500 - 500
5000 - 610
5500 - 650
6000 - 675
6500 - 660

RPM - TQ
4000 - 320
4500 - 560
5000 - 633
5500 - 620
6000 - 590
6500 - 565


Thanks

Larry, you dyno numbers also include cams and an upgraded maifold. I believe the original purpose of this graph/spreadsheet was a direct turbo comparison without any other majow upgrades. Someone correct me if I am wrong.

Those numbers are not very accurate. There is absolutely no way that a T66 can make more power than a 60, 63, or ts04 down low. Unless each turbo was dynoed on the same engine, on the same dyno under the same conditions, this chart is pretty useless.

I'm in total agreament. When I first looked at that chart I too had the same thoughts. For this to be even somewhat accurate and a good comparison, you must minimize all variables. The ONLY way to do that would be to dyno each turbo on the same car under the same atmospheric conditions etc...

PS
Larry I'm about ready for that SP 63. I'll call soon.

Yeah, after closer consideration and actually graphing the numbers in Excel, you are right. There is no way this chart can possibly be accurate. Either that or it is accurate and some numbers were 6-speed, aome auto, some turbo alone, and others were turbo + cams + manifold. No way to tell.

BTW, I am impressed that you extracted that power from a SP-63. I am real interested in what a SP-66 is doing to dyno, and how the curves are gonna look in comparison to the 63.

the sp60 and the sp63 can both make about 525 or so hp but the sp 623 does it at about 2-3 less psi. the sp63 can be pushed quite a bit past 525hp but it can still be used with stock feul, sound performance, please correct me if im wrong, this is what i got from my understanding.
