This is in fact EXACTLY what JMM do with the dev 4 and 5's. Read the articles on the JMM website and you will find that in 2 places they mention the need to run higher fuel pressure on dev 4 and 5 engines for proper fueling. tickford_6 wrote: and i havn't made a comment on the properties of copper. all i said is it will reacht he same temp as any other metal intake. because there is only so much heat available under the bonnet. It can't get any hotter then the air around it. Saying that copper gets to the same temp as other metals is misleading in this discussion. Yes it will get to the same temperature but it will pass more of this to the air inside the pipe - so the air comming out will be hotter. tickford_6 wrote: and you seem to leave out my comment on NOT EVERY MOD HAS TO INCREASE POWER.

i have read all of the JMM articles. and know exactly what they do with feul.
but again i ask you how is doing this copper intake to come out with what is most likly going to be no change in power and different to you buying bigger injectors that you have admitted were not needed. it's no different. you both spent money for minimal out come, |

Quote: DEV4 also has its own cam profile with upgrade valve springs while the fuelling department receives a remanufactured fuel pressure regulator. The remanufactured regulator helps achieve the appropriate mixtures, but ignition timing remains unaltered (except for across-the-board adjustment of the dizzy). These changes push power up to 160kW at the wheels
So they need more fuel pressure to hit 160rwkw now I hope we can stop talking about my god damn injectors!

Simple fact is 19lb injectors @ 275kpa are NOT upto the task of supplying enough fuel to engines with more than about 145rwkw. I max them out at arround 4200rpm.

Hey Frank. Long time no see. hehehe
You could get it HPC coated when you're finished. That'd make a few ppl stop their comments about heat transfer through the copper.
