Cooksport Megane, Big power Build... 600+bhp



  Cooksport Fleet
Cooksport’s Forged Megane Mk2.

Cooksport have built a range of Renaultsport road and race cars, but we have never really showed our work on this forum. As some of you may know, Cooksport currently maintain and support car number 66 in the 2012 Elf Clio Cup Championship. In 2011 Cooksport built and maintained a Renaultsport Megane Cup in the Production Touring Car Championship (PTCC). In the future we hope to have more progress threads of our cars and customers cars.

This progress thread is for our 2006 Renaultsport Megane 225. Some of you may have seen this car through many of its different states of modification. When I bought the car, apart from a Magnex (or similar) exhaust and a forge intercooler, it was standard.


We had a trip to the Nurburgring planned so we fitted the following –
  • AST Sportline 2 Coilovers
  • Decat Pipe
  • Stage 1 Map
  • Cooksport Induction system
  • Side exit exhaust.
  • Cooksport Harness bar
  • Harnesses
The car then looked like this.

Once we returned from the ring, it was time to take this a little further. So first off was an engine build, other than the usual preparation the Megane engine had the following:
  • Gas flowed head
  • Cosworth Pistons
  • Manley Rods
  • ARP head bolts
  • ARP main studs
  • Cooksport Exhaust manifold
  • Garrett GT2871R Turbo
  • Cooksport Decat and Exhaust system
  • Siemens 690cc Injectors
  • Cooksport Trial inlet manifold
Other Modifications included:
  • Quaife ATB Differential
  • Cooksport Induction Kit
  • Scan Gauge
  • Rear seats removed
  • Cobra Revolution seat
  • Spare wheel well/boot floor replacement
Here are a few more pictures including the Cooksport livery which was fitted for a while.

This is how the car stayed for a good 6 months; it was running approx. 380bhp with similar torque at 1.3 bar. Full boost was by 3500rpm and pulled the whole way to 7800rpm.



For more pictures of the engine build and fabrication from the first forged engine, check our Facebook page out. We don’t want to clutter this thread up too much ;) .


More interesting posts will follow.... :)

Very nice. Any chance you could do a build thread for the blue meg race car?

Now this looks like an interesting thread, can't wait to see what's next for it!! Are you going to be increasing the power at all?

Love that and I bet it f**king shifts. How is it on track with that sort of power?

Update

Now for the current build. We want over 600bhp. Why?......Why not?

To reach the power which we want we will be using the following
  • Garrett GTX35 Turbo with a .82 stainless exhaust housing
  • External Waste Gate
  • Clio 197 Cylinder Head (marginally flowed inlet, fully flowed exhaust ports) Inc. 3 angle valve seats.
  • Trial Cams
  • Megane Block with CP Pistons
  • Manley Rods
  • Uprated Valves
  • Custom Cooksport inlet manifold
  • Clio 197 Throttle body
  • Reverse run intercooler
  • Uprated Radiator
  • Long 750cc Injectors with Cooksport fuel rail
  • Twin Bosch 044 Pumps
  • Cooksport Custom Exhaust Manifold
  • Cooksport Turbo Damper
  • Cooksport Custom boost pipes
  • Standard ECU
  • Greddy Boost Controller
So, here are some pictures of the work which is currently in progress.

First off its the engine build.

Here is the block, freshly dipped, skimmed bored and honed ready for painting.

Masked up all ready for painting. We are going to be using the standard Cooksport colours of orange and black.

Block all painted and ready for build.

Crank in, with new bearings, thrust washers and ARP stud kit. Bearings plasti-gauged and end float checked.

Custom CP pistons :)

Piston and Manley rod connected ready for rings.

Ring gaps done, ACL big ends all plasti-gauged. Bottom end ready for cylinder head.

This is a picture of a standard 197 inlet manifold flange against the head. As you can see the injector path is nicely feeding into the side of the cylinder head. When using the standard 197 injectors, this is not an issue as they have an extended nossel past this lip. As we are going to be changing the injectors for high flow replacements without the extended nossel, the head needs modifying.

Cylinder head, acid dipped, skimmed, 3 angle valve seats. This picture shows our modification to the inlet port for the injectors. Valves need lapping and head assembling before fitting.

Top end and bare engine all completed. Engine timed up ready to go.

On a non-return basis? lol!

This should hopefully be the most powerful Megane in the world. Turbo is good for about 750 wheel horse power. :)

It will be bat s**t mental.

Big drag car wheels / tyres on the front? :approve:

Re: Cooksport Megane, Big power Build...

I remember that, f**king epic thing. Was only pulling 450 then iirc?

Be great to see it on the rollers now!

Well, there was a graph that read similar to that but it wasnt. It was nearer 380-390bhp. But the power delivery was epic.

That's pretty impressive to be aiming for that sort of power, you certainly have the right specification list though!

Will you be taking the car to any upcoming events?

600bhp is our safe estimate. Hopefully more.

Yes, it will hopefully be at Rockingham for our next Clio Cup meeting and the coming Renaultsport track day at Brands Hatch.
