any idea on the time taken to machine that? its awesome

 

ive been working on it off and on for about 2 years and ive kind of lost track of actual machine hours but at a guess id say 40 - 50 hours? 

if we made another one it would be way quicker but thats always the way.

That manifold is awesome man, a work of art. Which supercharger are you fitting? M112? Are you going to use any charge-cooling?

M122 and no cooling at this stage.

im not planing on over driving the charger at first so it will be fairly good temp wise. further down the track if i change it around ill think about cooling at that point.

cheers man. 

its a choice car to drive, lots of fun on the open road and when the road gets windy it really comes into its own. 

 

i remember having a brief yarn to you at the Toyota nationals last year. your car is really tidy man, be keen to see it again at some point.

Jesus fuck! You just keep ramping up the level of precision and skill on your cars bro!

I can't wait to see the car go with that superdupercharger on there! You should look into selling manifolds, I'm sure plenty of guys on the lextreme forums would pay good money for one!

yea i modeled it all from scratch.

took a while to get it right.

i basically measured a stock manifold to get the hole spacings then cut 1mm templates of the mating faces to match up with the stock manifold. with the templates i could see which holes didn't line up and move them around.

once id got the left and right side right then i made templates of the manifold holes both left and right side together to get the offsets between left and right correct.

then once id done that i went about doing flow analysis on different internal shapes to try to get it to flow evenly across all the ports.

then i machined it. 

easy.

yea that could happen.

TBH the 122 is running at the edge of its efficiency with the pulley its got on it. it would really only make more heat and fuck all else with a smaller pulley.

should do some proper calks i suppose because I'm going to be making a new pulley so if it could be smaller…….

I've probably missed something but.. once you've made the adaptor plate, will that not remove also your 10mm of current bonnet clearance?

ive taken that into account in my highly scientific calculations.

10mm adaptor plate should still give me 10mm clearance.

I thought you would have but also thought it worth a mention in case a pie deficiency had caused a momentary lapse in calculation.

vrrooom.

 

(I couldn't very well make a doort noise, and I mean, how do you make a supercharger noise as onomatopoeia)
