Renault F7R - Porting

[juuhanaa]

Hi,

I have been building a throttle body setup with bigger internals and i was thinking to compare this for a stock internal cylinder head. When i got the dyno testing done i can post the result here, but this is up to date later.

My plan is, when i get the throttle bodies setup i do it first with the engine i'm running now. After testing i swap the cylinder head what i have already done to see the difference.

Now i'm running freshly rebuild engine.

Bottom end is:

JE pistons, 12.5 comp and size 82.73
Maxspeeding rods
3kg flywheel
Fully balanced
ACL bearings
ATHENA 1.3mm head gasket
High tensile cylinder head and main shell bolts
Aircon. and hydraulic power steering delete


Cylinder head modifications:

Upgrade air filter
Finished head ports and valve guides were also cut down
Catcams 286/279
Exhaust manifold is modified so that it has even length primary and secondary tubes


Some other things:

Cam pulleys is from renault 1.5 dci engine. These need only minor modifications to make fit. Cam pulley sensor is also possible to fit. Please note NEW spare pulleys can be found like 15 pounds.


Ported cylinder head is explained in a video a made in rally English :-)

Great job.

From what I realized you ported the exhaust to 43mm correct?

The head is a megane one from the shape and side of the intake ports.

Is your block a 700, 710 or 714?

Hi and thanks for your interest!

Yes 43mm exhaust port correct and the inlet is 50mm x 33mm :lol: Block is F7R-710. Added also missing picture about the cam pulleys..

Got some progress and hope i get the dyno testing done in next month. http://williamsclio.co.uk/forum/attachment.php?attachmentid=9395&stc=1
