Taking guesses on BHP
I've my rolling road tomorrow, thought it'd be a bit of fun to take guesses on what power it'll make.
ST170 engine,
GSX-R 750 throttle bodies on ST manifold,
VVT pluged in, No Cat
Vernier pulley on Exhaust cam.
Omex 500 ecu,
I'll be happy with anything over 180. assuming it doesn't blow up

I love Pinto's, even if i did get mine from P&O!

210 bhp down the pub
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Because the inlet has Variable Valve Timing, would be a bugger to adjust me thinks
I'd take 150 at the wheels. What does that normally workout at after trans losses?

15-20% losses on a rwd car through transmission.
I reckon 150-155bhp at the wheels or 180-185 at the flywheel.

Well back with 180 in the stable. Didn't play with the exhaust cam and he thinks the exhaust collector could realise a few more ponies.
All in all very nice to drive, going to fix the dip in torque and play with cam after a cheeky cam regrind and i've seen what it's like to
live with.

VVT
Hi Dan
Is the dip in the power around the VVT kicking in?
Is it flowing enough air and what was the AFR map like?

Hmm
Looking at it again, sort that dip out and I think it will make more power, it is struggling to revover from that dip at 4000 / 4500 rpm its all over
by 6500.
Almost looks like its bad fueling before it comes on boost

The VVT does kick in at 4000, I'm ashamed to say but todays run was to get me on the road and was mostly limited by money.
From what i can remember, the afr went very rich at that point, down to 12.5. It did have serveral dips in it.

Fueling
So it sounds like it was cam timing or a lack of air then, it should have been able to use the fuel?
Did they swing the cam / Cams

No, he wanted me to drive it for a few weeks then taking it back with any issues, strangley it does feel flatter (if that make sence) than the old
engine.
