I posted this in the forced induction section so I will just include the link.

For those that are lazy and don't want to click the link, here is the dyno:

Nice job. Those are some nice numbers.

 

I saw them in the AEM forums.... nice numbers...

 

me to..just me without vtec at 7psi... hehe good numbers for us dogg

 

You have good numbers without vtec and at 7 psi. Could you post the dyno plot so we can compare the horsepower and torque curves? I would like to see how your a/f's are in boost. I'm running about 11.4-11.8 a/f's in boost.

 

Nice job.

 

Impressive

 

nice numbers...even though i already knew it...lol

 

Not bad man....

 

Damn thats nice!
250 whp, 200 wtq from 3600-6700
How is throttle response? That would make a nice street mod car.

 

what's your setup?? and what motor?

 

i dont have a scanner right yet. but my air fuel is level at 11 @3200 rpm.

 

The power and transition into boost and vtec is smooth and linear. Here is my setup:

1999 Honda Prelude Type SH
H22A4-stock bottem end
AEM EMS
Cometic HP style 0.057" headgasket
Portflow PnP head
entire Ferrea valvetrain with 0.5 mm overstock SS valves on intake and exhaust
RC Eng. 440 saturated injectors
Walbro 255 lph fuel pump
AEM camgears, fuel rail, fpr, and pulleys
Fmax turbo kit (modified to fit a bigger turbo)
Garrett T3/T4E stage 3 with 0.63 a/r and 60 trim with 0.60 a/r
2.5" testpipe and Apexi N1 exhaust

 

wtf.. how am i makiing so much power??
i dont have standalone or a pnp head. just some gude cams, exhaust, flywheel, clutch. ignion, race coil and few other little *****.. still need to tune.

 

what did you do to the ATTS?

 

Those are really good numbers. I'm impressed.

 

nice

 

i know i dyned saturday and im still smilying.

 

I also have a stock bottom end with an inlinepro headgasket that lowers compression to 9:1. I;m goin to street tune this week with a greddy emanage. With a good street tune would you think its ok to tune at 11psi at high boost(track). Daily boost set at .65 bar with wastegate. Did u use the autotune feature on your aem ems?
.
walbro 255 intank fuel pump
aem cam gears
2.5 testpipe
apex n1

 

thats pushing it on a H series.. but ive heard of some people doing it. i would dyno tune. this way u know your A/F ratio.. keep it around 12.5-13 ish

 

maybe its me but the engine makes 160-165whp stock @ 8psi you only made 93whp with a setup like that with a standalone maybe its just me a b16a do that or better with the same psi

 

Very nice Quaalude Grats

Do you have anything to retard the timing? Maybe your timing is more advanced than mine or your a/f's are leaner.

Disconnected the ATTS computer. I'm using the ATTS light as a shift light. I got a spare H22A1 that I'm going to resleeve and build up so I'm going to switch from a SH to a base.

 

My a/f's are in the 11.3-11.6:1 range. The dyno wideband reads a little bit leaner since the O2 sensor is in the tailpipe and my FJO NTK sensor is in the downpipe. If I leaned it out to 12.0:1 on the FJO, then I would have made more power but I was using the dyno wideband unstead of my datalogs because time cost $$ on a dyno. My compression is lowered to 9.4:1 with the Cometic headgasket and I'm only pushing 8 psi. If I had stock compression at the same boost level, then the numbers would be higher. Also, my timing is conservative. At 7250 rpm and 8 psi, my total timing is 23-24 deg. If I bump it up a couple of degrees, then I could have gained power but I didn't want to risk breaking a ringland on stock pistons since H-series pistons are know to be weak (seen and read from other peoples experiences).
