interesting you can spend the money to poke 40 psi and nos in there as well as the money to run a 800 hp car but you cant spend the money to re-engineer the studs in fact your rather use "stock" bolts to do what is completely out of there design spec i put it to you like this the reason you...

its not hard to do personally i never go bu manufatures specs whe it comes to bolt it simepl you need to know the material thred type and pitch and shank lenght from this you can work out the peak strength torque for the bolt and yes it is normally higer the the manufactura specs or you...

over tighting bolts does nothing other than weaken them v

yeap the gearbox has only move a inch or so to the left.. i just modded teh factory mount to fit that in there v

well guys ive been doing some work on it finally finished that adpter finally and its mounted in just the flywheel required now before that the mating is perminate v

different velocitys create different requirements it is posible to have a boundry layer that is bigger than the port and can inpeed flow there is mathmatics to work out the ideal finish......im not going into that here there is also a reasoning behind pointinh the injector directly down the...

thanks cobolt you hadn't posted when i started to write my last post but you sffort and attatude is very refreshing :D that SAE document i posted is not bad and is quite relevant :D cheers v

Boundary Layer Theory, by Schlichting, McGraw-Hill Book Company, Inc., 1960 go to your local libary and get it out if not there your local university ask yourself this i you came to my class and i told your the theroy surrounding this would you still think i was arogant or would you just...

i think you might be surprised.... have you ever seen a cnc machined port :D they alomost look polished but then they ruffen them up lol :D

well done at least someone has a done some looking into what i have said the guy before is the exact reason there is so much bulshit misinformation on the net...basically cant be bothered looking up things correctly and rather than look into some information that as i have said is well proven he...

i concure :S sorry nout that v

the point of the ruffing is to create a boudry layer this keeps the fuel from atually touching the walls and increases atamisation ........edited from a half asleep dribble sorry there brady

as i said read up on boundry layers they will explain to you why the fuel will not stay or even hit the wall in a properly textured finish where as on a polished finish it can have a tendance to pool creating a uncontrolled fueling situation and all the velocity in the world wont help if you...

some great thoughts there you got the reson why the ports dividers are longer he best porting you will ever see normally look quite subtle its called maximizing effect with minimal labour basically useing your experance to get the most effect with as little labour as you can just for refeance...

its called creating a boundry layer effect (google it if you want more info the dimples create a layer of air that effective supports the fuel suspention this layer effectively creates a swirling effect much like standing on ball bearingss this prevents the fast moving flow from touching or been...

would it not be a bad idea to have a list of people that have done work for the members here i mean you could post a price the time it took and a pic of the finished artical leat that way you hopfully know what your getting into v

t70 :D goes right up the middle of the compressor map :D v

i have seen 220 rwkw from a 1600 with a .48 to4e not bad so i would think with a 2l you wouldnt be far off
