att last dyno result :(
 

Hello everybody

Last summer i made engine rebuilding to my 911 targa.

Here is the were i started: Engine is 3.0l 204 hp row.

This is what i made : 3.0 L 9.8:1 cr 964 cams, Bursh haters,
valve job, litle port job, And MS II Efi.

Yesterday i went in dyno and now im litle pit confuset rwhp's.

It was 175rwhp an 5881 rpm
and torgue 225 Newton 3966 rpm

is that what it would be or is ther something wrong?

AF was too rihgts but not really wrong 12,8 , yes i know.
This dyno lapel is too big numpers because it was caliprated wrong. We have to minus -10% all numbers.

Is that at wheels or crank?

Max power at 5800 RPM? Did you map it yourself? How's ignition? Cams correctly timed?

Max power should be a little higher...I suggest checking cam timing and ignition timing. Other than that, it looks good!

Hello

It is Wheel hp 175 whits is measured.
What you mean for did i map it.
Yes i have to cheked cams timing, But it chould be 1,26mm.
Allso ignition should be 36 decrees at full throtle.

Thanks

did you use the same dyno

Factory rates hp at the crankshaft. If you have 175hp at the wheels you are producing aproximately 225hp at the crank. Thats a nice improvement.

The "Bursh haters" usually cost some hp on the dyno -sadly.

Yes "Bursh haters":D Sorry this language:cool:

To: pvj911, it's not any improvemen if i have 175hp at wheels. iI think that grank will then be something like 206hp
if you use 18% tranny lost.

That' s only something like 2hp gain:confused:

Like Noahs engine pruduses something like 203wheel hp.

He has same things in engine whits i have.

Eny idea where to start lookin those ponies;)

jukkis,
just wonder what about butt dino? does the car feel differnce before and after? how much differnce?
thanks

It is hard to say that Butt dyno because when i got it, i had some kilometres to drive, then i put it aparth. Then i used at least two years when it was ready to drive.

Thanks
