Turbocharged Dyno Result

[cdydjded]

Well today has been an interesting day. I posted an opinion earlier here & always a certain member which will remain nameless, critisize everything I stated. So I took this oportunity to dyno my car. I did this to see how much power I gained after I turbo'd my car & find out if what I was stating earlier was right or wrong. What I stated earlier was the following: you cant run TC injectors on a boosted Yaris without reprograming the ECU. What will happen is that you will run rich & have a high RPM misfire. I base this on 3 members who were boosted, were running TC injector & all suffered from high RPM misfires. Now I might be wrong & Ill be the first to admit it. So to prove my point I dyno my car and here are the results:

Run 1
Stock Injectors
Boost 4-5lbs
Max HP 151.77
Max TQ 133.49

AFR
3500 RPM 13.20
4000 RPM 13.00
4500 RPM 12.80
5000 RPM 12.80
5500 RPM 13.40
6000 RPM 13.20
6500 RPM 12.80

As you can see the car was running on the lean side. I knew & stated earlier that is was. I made 3 more runs and all the results were roughly the same. Runs 4-9 had the following results:

Run 9
1ZZ Injector
Boost 4-5lbs
Max HP 154.40
Max TQ 137.05

AFR
3500 RPM 10.00
4000 RPM 10.00
4500 RPM 10.00
5000 RPM 10.40
5500 RPM 11.20
6000 RPM 11.60
6500 RPM 10.20

Now Im running rich. I was going to raise the boost to 6-7lbs but was not able to. What I will do now is drive the car for about a week to see if the factory computer compinsates for the larger injector. Then I will install the TC injectors. Stay tuned........
