Dyno Results - Bensons 83mm/Eagle/CP LS/VTEC
 

I realize now what people mean when they say "Best exhaust for a Turbo is NO exhaust"

I have a tiny T3 .48 A/R Stage 2 turbine, with a 2.5" exhaust with an OEM cat. And the numbers show it.

291 WHP @ 7750
203 TRQ @ 7250

15 PSI Running 11.5:1 Air Fuel ratio

The compressor is a nice T04E .60 A/R, 57 Trim wheel, so that helped make more power than the average .48 turbine wheel produces.

The car still pulls like a freight train, and the power is usable on the street.

Would've liked to break the magical 300, but hey, the motor has a whole 700 kilometers on it. Maybe once I'm done breaking it in, I will upgrade the whole exhaust and re-tune for 350 WHP.

that's awesome. https://honda-tech.com/forums/images/smilies/emthup.gif how much boost?

Re: Dyno Results - Bensons 83mm/Eagle/CP LS/VTEC (Turboteggy)
 

WOW, not bad at all. How many lbs were you boosting?

I like that hp curve.

15 PSI

I'll try to find the tune page - it's hard to read though

The green line is the A/F. The line it ~ follows is 11.62

Ranges from 11.4 (low) to 11.8 (high)

The tune is VERY good and linear.

Who made the exhaust manifold?

did you dyno w/out the exhaust?

Re: Dyno Results - Bensons 83mm/Eagle/CP LS/VTEC (Turboteggy)
 

Lookin good Todd. Did Chris do the tune? Nice graph for the street and it looks safe https://honda-tech.com/forums/images...es/emsmile.gif You can tell it is starting to run out of turbo but that is ok for now. That mani looks nice, also. https://honda-tech.com/forums/images/smilies/emthup.gif

Re: Dyno Results - Bensons 83mm/Eagle/CP LS/VTEC (Turboteggy)
 

I have a VERY similar set up :
same turbo as you
2.5 " exuast (what seems to be holding me back per tom @ payn)
benson sleeved 83mm 9:1 cp/pauters b18c5 block
hondata /750cc rc's
walbro 255
etc
I just got back from the dyno and the similarities to yours are astounding:
@ 15psi :293.0 hp @ 8000 rpm / 211 ft-lbs @ 6250
and
@ 19psi : 331.7 hp @8000 rpm/243.6 ft/lbs @ 6250
all on a mustang dyno as well.

I just though the similarities were striking in both set ups and wish I had a way to post my graph http://images.honda-tech.com/set1//smile/emcrook.gif

Good numbers Todd drive the car this year do not get to aggressive on it and have probs

Re: Dyno Results - Bensons 83mm/Eagle/CP LS/VTEC (JDMCRX)
 

Don't worry, on a dynojet you are probally over 300whp, so there ya go! Also, upgrade that exhaust and I'm sure you'll reach 250whp. I had a stock caton my car, with stock B-pipe and RSR ex mag, and damn that shit was restrictive.

My best friend. It's just a log mani, but I had it cerma-chromed. The wastegate dump is not as pretty, as it originally gonna be open dump, but I changed my mind halfway through, so it is kinda quick job, but it works.

Thanks Earl, yeah, Chris did the tune. Said it was about as high as he's seen a .48 A/R Stage 2 turbine go as far as HP on Honda's. I'm guessing the 4-bolt outlet on the turbin, and unusually large compressor (for that turbine) made the diff. I think if we went to 8K, it would've hit 300 - it was definitely on track. Ah well, I wouldn't feel the extra 9 HP anyways......

Overall, I am pretty happy, we'll see if I get bored whether or not the exhaust/turbine will be upgraded.... https://honda-tech.com/forums/images/smilies/emwink.gif https://honda-tech.com/forums/images/smilies/emthup.gif

Another great job by Chris at Tapp Auto!
