Zach is a Navy guy that has had the Evo for awhile and a dream. He wanted to have the fastest spooling and biggest powerband for road racing he could and still run 92 octane. We went to work and were able to produce a really good compromise for the goals.

Mods-

ER 2.3L
Wiseco 1400HD 9:1 stroker pistons
OE 100mm crankshaft
Eagle rods
ER Street Port cylinder head
Kiggly valvesprings
GSC S2 camshaft set
GSC valves
Forced Performance DBB Black
JDL O2 dump
Fuel Injector Clinic 900cc injectors
ETS 3.5" FMIC kit
Omnipower 4 bar
ER SD road race tune
3" TBE
Hallman MBC



I left run 7 on to show the difference 1 degree of timing can make to the overall shape of the powerband. While it didnt really seem that it needed the degree around 7200, everywhere else liked it.

wow, nice job on the spool. nice for 92 octane

It came together pretty well. We will see how it does on the track but I am sure its going to be what the doctor ordered.

Pardon me if I'm reading it incorrectly, but ~12afr on 92octane?

Yes...our sniffer varies from the onboard but I run 12.0 all the time. This one was more like 11.2 though since it will be tracked.

Word!

The red you tuned in my boys 9 pulled 430.. On oregon pump. He has S2 , o2 dump , and a ets intercooler on all stock pipes.. But the motor is stock. Am I crazy? What numbers would you expect on a red with this motor?

JohnBradley

About the same power with better spool. The Green/Red/Black all make about the same on pumpgas and "low" boost. The Red and Black need 30+ to really come alive so they dont ever really do more than this on 92 octane.

makes since, wasn't doubting your skills, just wondering what the word was. thanks for the reply

Porting the FP Black will allow it to make more power up top, right? An unported FP Black will make torque sooner but then taper off up top, right? And E85 will allow the spool to happen sooner, right?

I am looking to see what turbo (Green, Red, Black) would give me the greatest powerband with 30+PSI on a 2.3L. I like to use pump gas numbers in my decision making so this thread is nice for that.

Full boost around 3,700RPM (and holding throughout) and starting to taper (torque wise) around the mid 6,500RPM range.

Porting is about backpressure control but some of it is also to keep the turbo from creeping out of control. Multiple directions that happen under the blanket of "porting" so one can do different things and call it a port job.

30psi on straight pumpgas on 93 I have seen 490-525 from both the Red and the Black. Every part of the combo was optimal to do that though, not what I would call easily repeatable.

I am sorry. I forgot to mention that I will be on E85 at 30PSI. Thank you for clearing up the advantages of porting. I see that it is more beneficial. As for the "not repeatable" aspect, I totally understand that and I am not one to try to extract every single bit of power out of a set up. I basically like to enjoy a powerful EVO and not have to worry about anything breaking.
