at the end of the day your wallet will deside what you buy,if we all had deep pockets we would have the best. i can get rotors off indy cars if anyones interested? there rated to 300mph good price too at 180us per rotor made by performance friction,steel not carbon

i did my ticket may years ago and then became a toolmaker,then after that took up design engineer and cadcam engineer which are all just bits of paper,lolol now i just design and build custom turbos for people around the plant so that consumes alot of my time. yes the labour thing,it turned into more a love of labour but it was interesting and fun to do.

ive never had a problem doing them,the better the condition does help to get life from them as you dont want to go below min thickness. vented or non vented isnt a problem,even the brakes on my open 250 kart are slotted and there only 6mm

i haven't kept my ticket up which was i believe 4711, and since I'm not building to many bridges these days its not allot of point to be honest unless your after the bling factor or weight saving the carbon way isn't cheap and dam time consuming,the two we did one was on a 911 turbo and the other a Lexus v8 they looked great but a pain to build,we even did cooler piping from carbon and vacuumed it and dam they were light and strong and that was worth the time. used PVC piping to make the shapes we wanted and molded them on the inside,you could bounce a sledge hammer of them

thats true but looking at the surface area of the manifold being too big with no reinforcing it would balloon out and burst,even carbon fibre ones ive made in the past we needed atleast 8mm thickness to withstand 20psi. when we went thinner we also got pulsing under vacum giving poor vacum signal.

lift pump to the surge tank,out of tank to feed pump---> fuel rail---->out of reg---> to the main fuel tank, out of the top of the surge tank i put a 2.5mm hole feeding a 1/4" hose which is feed back to the main tank. this is done to bleed any air from the surge tank and takes the piggy back effect away from the main feed pump. you main tank acts as a better heat sink than a small surge tank,you can also run a moroso cool tank after the main feed pump to keep fuel temps down but that works better for drag racing as you use ice inside of it.

workshop is 098107009

35 per rotor

just buy stock rotors of which ever brand you like and have them slotted, i use to slot 20 sets a week

a 1ltr surge tank is more than enough to feed most cars, a 650hp v8 around puke at WOT will use 1ltr of gas so any bigger is a waste of time. i also never feed the return for the fuel rail to the surge tank as its hot fuel which does nothing for performance or trying to stop detonation.

when i make any intake manifold under presure i never using any ally under 5mm thick the plenum should be around 2x engine displacment and avoid sqaure ends or corners to spilt a setup like that can also be caused by cam timing out or to lean on overun,or a valve not seating causing a backfire blow valves sit before the manifold and dont affect them in anyway to cause the manifold to split,

yep pretty much not that many can identify with it,pretty cool to brag that your hair dryer is worth more than the average new car,lol wait till you see the paint job that ll upset the purist that own a beemer,lol and it wont be pretty

on the money with the pistons,as for the rods theres afew to pick from but they need alittle work to fit.

yes theres better gains from doing both fuel and ignition, the afc is great for a quick adjustment but they only work in 2d but you still see a good gain. the map2 covers sooo much more and is very user friendly for install and tune. im using a stock ecu for my 5 series turbo with the map2 just to prove a point to how far you can push things. it seems on here alot of things fall on deaf ears, just cause its a bmw doesnt mean you cant do it. wait and see what pistons and rods are going into my m20,thatll rattle some cages

put one in my e36 and e34 about a year ago, they work good did tell but most on here arnt interested so i didnt bother writting a post about it it does seem very clicky on here at times

E: Just removed quoted original pics from reply to save real estate

arr thought so ive repaired afew of those, ill post a pic of whats going on mine

out of interest whats the turbo and brand

MAPECU.COM ive already tuned a bmw with it and putting one in my turbo m20 2.5 and another into my 318i, very easy to tune and does lots of other things like switchable tables,launch control,boost control, speedcut/boost cut, o2 control obd2,etc etc

ive done it before many times and you can get gains from it, to correct the a/f i used a apexi afc which im still using in my e36. the better way would be a mapecu2 to dump the afm and then you can do ignition as well, this also allows you to do ITB or what ever you like as it uses a map which doesnt care what goes on. then if you deside to turbo,life is easier

i make under-drive pulleys for many different vehicles,the alternator can rob 7-12 hp and water pump around he same to which is why race cars run an electric pump and the alternator runs off the drive shaft. they don't go to these degrees if there wasn't a noticeable gain. water pump conversion to electric on a small block is worth 20hp at the wheels,cant complain about that. the other reason apart from power gains( which are real !!) is with the water pump it stops it cavitating at higher rpm to aid cooling. you notice the gain everywhere not just at high rpm. so there's maybe something in that magic every little thing helps when playing with na,smaller lighter etc maybe only 5-6 hp here and there but combined together could at up to a noticable gain. I'm looking at making my own multi throttle body setup on my m40, i only listen to those who can prove to me certain things arnt worth the gain. then there's those with their heads stuck in the sand,just cause its a bmw doesnt mean it cant be done

cheers theres also a very large hair dryer blowing through them,which should help

theres alot more to come and things dont have to cost a fortune,it run the map ecu with stock ecu which means of you dont want to run a airbox then just run 6x filters im alos looking at running the injectors before the trumpets
