Dies a bit early, not?

[Exmantaa]

This was my 2.0 B207/LSJ Harrop on the Maha rollers last year with the 80mm pulley and 2.5 exhaust system.

I was also a bit rich till 6000rpm and not sure on the max torque figures, but you clearly see the different torque shape of you 2.2 volume engine:

[TFD]

Thats 339hp at the fly,correct? Should be more I guess when looking at your fuelsetup. 630cc@1.4~ish bar of boost (correct?) =~768cc flow. 768cc@85% DC should be in the 380bhp (330ish whp) range according calculations (http://www.witchhunt...jectorcalc1.php ).

 

A calculaton is just what it is, but when running almost full puff on 630's then 339hp seems a bit low 

 

Interested what the logs say.

Don't forget the power needed to turn that big Harrop SC...

how much is that

Anything particular you want me to check and share

16 psi  /  1.1 bar

 

and only 80% duty cycle today

3. Smiley 326 bhp wheels
4. Batman 331bhp
5. Haggie 364.7 bhp

looks like the Captain was closest 

and haggie was miles out 

 

lol

That 1.1 bar is a "mild" boost pressure for the Harrop and you could do with a bit smaller pulley? But then low SC boost is good for your IAT on track.

 

(There are on-line calculators that estimate HP from the injector duty cycle. This one f.i.=> http://www.witchhunt...ectorcalc1.php)

A hollow victory - lower result than we all expected.

 

Taking a step back, you have power comparable to the Exige S and Lotus needed a 3.5 v6 and a supercharger to get the same power. Overall a pretty impressive power/torque graph.

[The Batman]

Change the sc pulley and Rev that v6 high and that will be an awesome engine One day...

That is a very good point

[CHILL Gone DUTCH]

If you fast forward this vid to 11 mins 40 seconds There is a comparison there

[CHILL Gone DUTCH]

well how accurate is the dutch software reading #

 

[CHILL Gone DUTCH]

ive now just got to find the lost horses

[Exmantaa]

That is pretty good!

As we've seen more here. power numbers match but often the max torque values differ quite a bit

(299lb.ft = ~405Nm)

 

Can you show up a MAP log to check if you maybe had belt slip?

[smiley]

Your previous peak was 382 in cold weather right? (which was extremely high for a 3.1/80mm pully)

That's a lot to loose without any changes.

WTF?

im not sure whats been happening to be honest but im now on it 

 

i had i miisfire this morning which was strange, which seemed to clear its self up after changing my transient setting back to what they were before i changed them at the beginning of the month 

 

im actually going to go out and do a full fuel learn and take it from there 

 

if this is whayt he power is then so be it, has peter changed the callabration in the new software ?? 

as it could be this
