Interested in how much power you put on the ground (not the stated 213 whp obviously..).

Should organise another Dutch dyno day 

[Exmantaa]

We should organise that yeah.

Power to the wheels is always a bit tricky on that MAHA dyno with the twin rollers. Not too bad on a straight solid axle, but the VX/Speedster with quite some toe-in and loaded with 2 people on the back create quite some loss there.

 

(Chill; 2.5" graph is 1 page back. Need to overlay the graphs and compare the logged MAP pressures.)

Is that usable with the 2.5" run cut off at 6800?

 

[CHILL Gone DUTCH]

If your map pressures go down you should be able to get more ignition in

Has anyone got and pics of there b207 block from the top please

[CHILL Gone DUTCH]

We're all the blocks Gen 1 blocks then ?

[CHILL Gone DUTCH]

The main reason I ask I spotted this pic


Which is possibly Stefan block and appears to be a later Gen 1 or 2

Yes.

Looks like it's had new sleeves.

[CHILL Gone DUTCH]

LOoks like a later Gen block to me

B207R from saabpartners.com in the Netherlands.

Looks like a bock stock B207 (gen 1) foam cast press-sleeve engine block to me...

Maybe you are confused because on that pic the headgasket is lying on top of the sleeves??

 

The B207's do not have the reinforced cast-in sleeves. You need a 2012 sandcast "Gen 3" (actually gen 2.5) for that ands the right versions are all DI-VVT type engines.

[CHILL Gone DUTCH]

Ah Didn't realise the gasket was on there Cheers frank

[CHILL Gone DUTCH]

Yes.

 

i think the B207 are gen 2 

which is not good 

and for this reason i am not going to be pushing any further with a smaller pulley 

[siztenboots]

is there a comparison of the piston+rods weight across the ecotec range

The block system seem to be a minefield never mind the internals. 😓

[color=rgb(40,40,40);][font="helvetica;"]Will look for his engine specs at that time, but the rpm reading was a bit off and so was the power.

Water injection working it's magic I see?

 

Should update my profile too. This was my MAHA dyno run in october last year (2nd run after 1st had wheel slip and I asked to run it straight into the limiter @8K.)  After this I have worked on ignition timing and it's now closer to 360 with more torque spread, but needs water injection to keep this power on hot track days.

Stock 2.0 B207/SLJ bottom end though :
