Turbo Testing
-
Just finished testing the S200 in T3/T4 form. Very happy w/ the results. We did no tuning except for on the top end to prevent leaning out. Results below.
22 psi: 466whp/307trq
25 psi: 493whp/342 trq
30 psi: 552whp/439 trqI'll post the graphs as soon as i get them uploaded. The turbo maxed out @ 30 psi as you'll notice on the 30 psi graph. We tried 32 psi but it just didn't want anymore. Made 559 on 32 psi. Pretty impressive from a little 55lb/min turbo.

Ok...Im dumb with turbo's, I will admit it. So is it bad to push a turbo to its limits like that and how do you know when its at its max??

Once we get the 30 psi graphs up you'll notice the airflow was maxed out based off the powerband. On the 550+ pulls power peaked @ 7000 and just held flat to 8500. Going from 30-32 psi only netted 7whp which should have been an easy 20+. This turbo is only rated @ a max of 550hp. So we met and exceeded that @ a very low boost level being these things are effiecient into the 40-50psi range.

Ok....Makes a little more since now...Ive been looking into turbos a little for the hatch...Not sure if I am going all motor yet or boost it...Need some money. Just getting some ideas for now to see what I am going to need/get myself into.

All motor cars are worthless.

Yea...This boost thing is winning me over right now...I would be satisfied with 250whp for a daily driven civic...I know its not a lot but I dont want to build a motor big time to take the boost...I got the new Dsport mag and they have a EG with a y8 with stock internals making 260whp...I like that idea but I would upgrade internals a little.

I saw that...Didnt you run like 11.4 on slicks?? How much would that exact turbo setup cost on a y8??

A/F was borderline at the end. Finally ran out of injector. Otherwise we maintained right around 11.8:1 to 12.0:1. We didn't spend much time on tuning, spoolup was FAT and under boost we just tried to keep flat around the 11.8:1 area. I am sure there would be more power if we would have actually spent the time going through timing tables and so on. Just a safe generic tune on each power level.
I have the runfiles but the runviewer sucks and doesn't work as well as the actual WinPEP software. Andy's printer was acting up so once he gets those mailed up we'll get them scanned and posted online.
