Rally Rolla ZRE-152

[smee]

150 is proven by engine builder. A number of similar builds are putting out that figure at the wheels with the same set-up. 

Rally tyres, 45 degrees and tie down set-up all combined to rid run of hp.  CAMS switching in at 5000 not 6250, so will fix that. You can see power drop on graphic when output. This may be partial cause.

Ah ok, I didn't realise it was a rebuilt engine.

[smee]

Wiseco pistons, corillo rods, Darton sleeves, strengthened valve springs and oil pump, 550cc injectors, remote oil cooler and better gearing.  All help to get more power out.

Carrillo make very good conrods, I am impressed with the manufacturing quality on mine.

That's a solid foundation for an engine, especially under the conditions that you will be putting it through. I can't see it having any reliability issues.

Unless there is a mechanical/electrical fault on a component, I would think your issues are down to tuning.

Have the lift bolts and lift filter screen been replaced in the process?

[smee]

As far as I am aware.

Can't hurt to check for yourself, if you find no other solution. At worst you need to replace a few gaskets.

The other option is to contact the builder.

Found an extra 40kw.

Updating the ecu with some appropriate figures, and we will see where we can get to.

Nice sounding engine and exhaust. Interesting seeing the vehicle body movement on the dyno.

You should see what some massive horsepower cars do then.

Cam actuation not set in the ecu.  Different dyno and better fuel mapping.

Not as hot, and lambda and fuel pressure changes.

I thought as much. It probably would have made the biggest difference.

How far off your goal figure is it currently?

[smee]

pretty much there.

Dyno reads under, so engine is in a safe state.

Final log file and map sent to builder for review.

[smee]

Took a while, but Log Book and Cage Sticker obtained.

[trentmeyer23]

Nearly time to go racing.

Hopefully Thursday night

Need people get their act together and enter the twilight rallysprint here in Adelaide.

As of this morning, 13 entrants.

Need at least 25 to make it start.

[smee]

Been a while, but here you go.
First real run, and I scratched it.

Loved it!!

Nice to see it out and about. Sad to see it scratched, but that is part of the fun I guess.

Some external video of the car.
Last segment has the car accelerate, and you can here us pick 4th.
Sounds very nice on full song.
