Are these figures at the fly wheel or at the wheels on the road???

these would be good figures at the wheels, did you do a run down calc? i know these are not very accurate but would be a reasonable idea. my best on the rollers was around 215 bhp at the wheels, this was a std car.
as for the inlet manifold, how far did you go? did you open out right up to the valve or just the top portion? i think there are merits in doing this with this engine. another decent mod is to use a manifold spacer, seem a lot more go at the top end.
also interesting you say yours was running lean at the top end, my std car runs mega rich at the top end around 11:1 at 7000 flat out.
i think this figure is about the same as tims if its at the wheels. let us know about the manifolds.

Run down Calc yes very small figures at the bottom are the max min with run down losses.

Some info and picts for the manifold

It did run rich until we began mapping, one the maps made good HP's but ran the car to lean. Have to be slightly aware being a covered rear engine not to go to lean as cooling can become a issue better safe than sorry so only 274 for me lol

Might help explain

So 302.2bhp at the flywheel, wow, thats unheard of with one of these, whats yor secret?

Ben i wish i would have met you years ago fella!!1 You would have saved me a damn fortune!! Sorry to keep asking questions even though you dont bother answering them, but - is this also mapped on the standard ecu? I know a couple of people who do specifically renault ecu work ( yes they are boffins) and they say the "mapping" is very limited, generally to ignition and fuelling on the standard ecu....

Thanks Tim

Mapped on the standard ECU, unfortunatly im not one of the ECU boffins at work i know how it all works but i dont do the map writing myself. As far as the guys have told me it is a Bosch ecu that is widely used across a range of cars and manufacturers they didnt seem to have any issues working on it. In fact it was nice and easy compared to some of the stuff we see

thanks again too spike for inlet spacers and ben for he's pictures on porting the inlet manifold ,yes i must of took about 5mm out of each hole and then wet and dry the in sides ,Then autosolve the inside i would advise anyone too buy a set of spacers from spike they fit perfect and thanks ben for the advice.

Thanks lee for the post i am glad you are happy with them, i will get some more made ready for the rush! hope all goes well and lets see some dyno figures.
after this mod can you tell us how the car actually feels, and does it upset the overall feel/aspect of the car? also fuel consumption would be good to post in the future.

It is best not to polish the inlet from the injector down. A brushed/scotched surface is best as it avoids fuel droplets forming on the surface of the ally. A mirror finish on the exhaust is always best though.
