Sorry everyone this is a blatent advert for me and a few others....

This afternoon, my friend Nick Lewis (a NEW PF user NIL 7090)
had his cosworth YB engine dynoed at Norris Designs.

The engine specification is as follows....

ENGINE SPECED/BUILT BY NORRIS DESIGNS (DAVE MIDGLEY / SIMON NORRIS / NICK LEWIS)
MAPPED BY SIMON NORRIS
HEAD PORTING AND TEA MAKING BY SPENCER ATHAY (aka PF spenner)
CAPACITY 2.0 LITRES
JE PISTONS TO NORRIS DESIGNS SPEC.
COMPRESSION RATIO (NOT DISCLOSED)
4 x 1000cc SARD FUEL INJECTORS
SWEDISH INLET MANIFOLD (SUPPLIED BY MIKE RAINBIRD)
METRO 6R4 THROTTLE BODY
GARRET GT30/40 HYBRID WITH EXTERNAL WASTEGATE
BOOST LIMITED TO 2.0 BAR AT ALL TIMES ELECTRONICALLY
8200 rpm REV LIMIT
PORTED HEAD (STANDARD SIZE VALVES)
CAMS NORRIS DESIGNS SPEC.
CAM VERNIERS
SOLID LIFTERS
LONG STUDDED HEAD BOLTS
METAL 3 LAYER HEAD GASKET
LIGHTENED FLYWHEEL
BLUE PRINTED AND BALANCED CRANK/RODS
HIGH FLOW PISTON OIL JETS
OIL COOLER
SPEC R CUSTOMISED 4 PORT BREATHER SYSTEM
ALLOY CRANK PULLEY WITH IRON LUGS FOR CRANK SENSOR
SECS S8 ENGINE MANAGMENT
SECS S8 COIL PACK IGNITION SYSTEM
5 BAR MAP SENSOR
CLOSED LOOP LAMBDA FUELLING (NOT AT FULL LOAD)


The engine was initialy started and mapped for idle and acheives a stable idle
at 1000 rpm with a lambda reading of 1.00 (AFR 14.7:1)

Then the engine was fully mapped with a flat line controlled maximum boost of 2.0 Bar.
The fuel was then changed for race fuel and the ignition table modified and then
a second maping session with power run was made.
I wanted them to run a bit more boost personally but the engine was mapped conservativley
due to Nick shitting him self and not wanting to rebuild it too often !

I must say I have rarely seen such a flat torque curve as on this engine and remember
it is torque that gives acceleration.

Just remember, this is ONLY still a 2.0 litre and does NOT run NOS.

I cannot give any further specifications/details as these were not given to me and/or
the engine builders were keeping it a bit quiet.


The results....
PUMP FUEL 97 RON: 584 bhp @ 7440 rpm / 450 lb/ft @ 6090 rpm
RACE FUEL 118 RON: 632 bhp @ 7650 rpm / 474 lb/ft @ 6040 rpm

NICK PRETENDING TO BE A MAPPER


Bugger, forgot to get pictures of ECU

Thanks to Nick Lewis and Simon Norris for putting faith in the S8

Right, let the put downs comence .....

 

Excellent work!!! Just look at that torque line!

 

TOP WORK SIMON AND ALL INVOLVED

 

Respect!

 

Simon, would have been good to see a run at 2.2/2.4 BAR

Me next!!!!!!

 

Fair fucking play. Nice one.

I didn't realise just porting the head would allow it to flow enough to reach that power.

 

Superb Simon. As you say would have been great to run a touch more boost.

I think the torque curve is fantastic!

 

Well done boys

 

Std size cossie valves are good for over 600bhp I had been informed previously

 

Grats mate, really pleased for you It must be really satisfying seeing your own product perform so well.

 

There is MORE to it than that. Cams/Manifold/turbo ... MONEY

 

Thanks for that Karl. It means alot when someone of your reputation
makes such a statement.

Unfortunately, I can only take credit for the ECU system.

 

Fair play, esp the good power on pump fuel

 

I know it needs a good combination of the above, I just imagined that at that level bigger valves would have been a given seeing as people tend to say that you need headwork for a genuine 400.

 

impressive torque curve,,, will make a crackign fast car! the torque hasnt tailed much

 

 

Some stats:

Add together the BHP output of Porkie's, Brom's and Nick's engines - ALL running SECS S8....and you got 1,856 BHP

Then add Phils DIY engine (488 BHP) ??????? whats the total for the four engines?

2,344 BHP ???

 

is very impressive any idea on the crank just for interests sake?

 

What car is it going in? 2wd or 4wd?

Immense torque curve!

 

Doug, then fit them all in one car. LOL

 

I THINK the crank is standard apart from being knife edged and surface
tension relieved by shot peening.

 

Hhhmmmmmmm I wonder

 

WHAT A TOP RESULT ALSO VERY QUIET ENGINE AT HIGH REVS SOUNDED LOVELY WELL DONE NICK MINES NEXT OH BUGGER WELL DONE NORRIE WHAT A PUKKA JOB AND DAVE TOP ENGINE BUILDER AND SIMONS E.C.U IS THE DANGLIES BOUNDARIES ARE NOW BEING PUSHED 700 THE NEXT MILESTONE WITHOUT NOS ANY TAKERS

 

Its going in a 4wd saffy with all the trick transmission.
Dont know what type this will be though.

 

THE CARS A 4WD SAPPH

 

Simon I bet Nicks happy Cant wait till he starts going to the shootouts will be very fast,
You may want to edit and put in Who did the head work as you never know who will take the credit .

Mark

 

Is that another unecessary Dig Shady?

 

Simon, can you say who did the head work???

 

Can't wait to see the car in action then!

Wonder what 0-100 times it will set? Should be knocking on the door of Martooon with the race fuel in?

 

Sorry, forgot. Thanks for the reminder.

It was that chap "spenner" who did the head job

 

Spenner did the head work AND made the tea?????????

 

DONT TURN THIS INTO TUNER WARS FFS

 

FAIR PLAY MATE
very good result!!

TOP ROD!

 

AGREE 100% - Just because 1 person/tuner has big power does not mean
no one else cant do the same !

 

Well done Simon, and all others concerned

 

Yes I forgot Spenncer did the head He always makes the tea , Cant wait till he goes for 1/4mile and top speed It should be on for 195+mph .

Mark

 

wel done simon and nick etc etc

good to have it finally sorted hey

 

madevelopments, Thanks for the positive comments Mark.
I am sure Nick will have a play with the big boys one day soon.

 

not a dig or anything but why wasnt trick rods used so the revs can rise to high 8000 looking at that surly would see well over 600 bhp on pump fuel if the revs where to climb and more boost

well done carnt wait to get mine strapped on the dyno so see what it will put out wont be long now

 

nice dyno proven what we like to see aswell
