Rolling Road how many horses do you think

[CHIMV8]

Car was at V8 Developments last year for full engine rebuild.

First time on rolling road since the work next week.

Work done
Rob stripped down the engine and acid dipped and rebuilt it including
New Clutch
Stealth cam
Stage 3 heads
Ported inlet manifolds and 45mm trumpets
72mm plenum
Lightened flywheel
Cam and cranke bearings,shells etc
Removed pre cats
Basically nearly everything replaced!!

Recently also had main cat out and ACT smooth bore induction system

Running standard rear box silencer

This will either be a pleasent surprise or a disappointing downer dependent on results.

Last dyno run the car made 220bhp

What do you think the estimated increase will be

What mapping work have you had done after all that work? Looks like your still on the 14cux.

But i will go for 250bhp.

Not on the same RR with similar conditions.. Irrelevant. If it feels stronger then brilliant!

[Discopotatoes]

269.3 on the nose

[ChimpOnGas]

267.8

[MPoxon]

265

Are the valves the same size as before or does the 'stage 3' mean bigger valves.

Standard valves...235 @fly
Big Valve......255 @ fly
