like anything.you are paying for the hundreds of hours development,they didnt just weld together any old bits of tube.
Although i also think the price is high.
Look at the torque tube,its a piece of box section for £285!!
Was thinking about it too, looks simple enough. would it better to tapper the tube as it gets to the last runner to equal pressure on each runner?? and to use one piece of metal for the top and sides, curve it like a U the other way up?? simpler, less welding
What factors would it include?? inlet diameter, pressure lose per runner,
Hang on though, if the chamber is for N/A then the runner suck the air in, so as the pressure never goes positive would really affect it, turbo would. That a nuts thought??
velos dont taper either system so maybe on NA it the engine sucks the air it needs,after all its only air,petrol is injected last thing so it prob dont matter.
Lotus desighned the head,and vaux said it was too powerful so lotus had to restrict it with the mad inlet system.
I wonder what the origional lotus inlet looked like,and if we could get a pic or info from anywhere,Is it worth an email to lotus?
Defo, that would be worth a look at. I want to produce one for a turbo application though. Want to get big power, so need to get it all right. but if it's only cheap to make one, why not try different designs??
fabricating and repairing injection moulding machines.
So i have access to loads of materials and lathes,mills etc
Also the Reasearch and development engineer is my mate,which could come in handy for drawings etc,im gonna have a chat with him about this on monday,see what he has to say,ill let you know.
He is a real boffin,he had a hand in the R+D of the rover K series 16v engine when he worked at rover.
I after the head off a GSi, cause it does have all the egr s**t ports going throught the head and bigger port size. yeah would be dead nice and the sound of it too. the stainless filters sound awsome. Mate had one on his GT4, when the turbo span up sounded like a jet on tick ova. Want one!!
Don't underestimate Velos. I have visited them a number of times and can highly recomend them. They are a small operation and pay alot of attention to detail. There work is based on vast experience and every engine build is treated as if one of their own. The guys are genuinely excited by what they do, and are very helpfull in setting up and aftersales treatment. Its almost like they build engines for fun rather than making money. Charles Paynter a.k.a CP has had the full works from them. They have built a fantastic engine for very reasonable money.
As far as the design of the plenum goes, I'd say there's far more engineering in their "Bean Can" than any of the alternatives, and looking at the design, I'd say it would possibly show the best results. The inlet angle runs from the ports at the same angle as they exit from the head, just like TB's.
