Hello again, my electronic boost controller works by sensing the boost pressure in the intake manifold/ boost pipes after the intercooler, it has a digital microprossesor that interprets the data and controls a solenoid (at 400hz- four hundred times a second)that then controls the air fed to the pnuematic actuator and then the wastegate - it is completely seperate from the cars' electronics, but works alongside them, it has a 120psi solenoid so theoretically could work up to that PSI it has a digitally mapped - anti-lag programme built in - it outperforms any other system (in my opinion) - it was very expensive (designed for drift racing) but somtimes when you get the "best" it saves you wasting money messing about changing several "lesser" ones
the boost controller has 2 fully adjustable stages, + a defeat/ fail: safe (if the boost controoler fails/ powers down the turbo actuator still works)
Unfortunately it won't work with your car/ engine, unless you retrofit a pnematic actuator, i have seen electronic boxes that connect to the MAF sensor that "up" the boost pressure, on cars with electronic actuators
Incedentally the anti-lag system (seperate from the boost controller, which has an anti- lag programme) works by dumping the air out of the (pnumatic) actuator when i lift - off the throttle, this means when i go back on the throttle,(after a gearchange or "lifting off" ) the wastegate is always already shut, so boost can build up quicker (anti - lag)
"short shifter" "quick shifter" - the gear lever is shorter, with a shorter "throw" (often with re-positioned/ adjustable pick-up points) gears can be changed quicker, and more positively, if you are trying to change gear quickly you are also less liable to "miss" a gear, - it can reduce your 0-60mph/ 0-100mph times/ gearchange times a little (on the autobann , of course

)
The external waterspray is very simple, it is just the same as a windscreen washer spray, but it sprays on the intercooler - i made mine out of spare parts- you could too (its easy) it does not need any special map/ setup, i saw it on "top gear" on a Mitzibushi EVO, it works well on a hot day, or sitting in traffic / waiting for your 1/4 mile run etc (reducing heatsoak)
Your car looks good! those wheels are heavy though, (22kgs, with tyres- same as ST 18" wheels), you would be better with mk3 Mondeo titanium X 18" wheels (20kgs, with tyres) or early 16" tyres (17.4kgs, with tyres) or what i run, steel wheels (also 17.4kgs)
the lighter wheels reduce the unsprung weight, and the rotating mass, narrower tyres reduce the mechanical and aerodynamic drag (but can reduce grip on takoff/ cornering) - the mk3 titanium x wheels are wider AND lighter than your wheels (by 8kgs overall) the (17.4kgs) steelies i run save 18.4 kgs (of overall weight, unsprung weight, and rotating mass)
not having the spare wheel/ jack/ brace saves another 20kgs (i use a footpump and tyre foam) and the weight off the back improves the traction
to list all the other modifications (or just the weight saving items) would take pages and pages, but briefly, the weight saving is about 150kgs, the lighter wheels/ no spare alone is minus 48.4kgs, the decat/ exhaust is minus 9.5kgs the aircon (never used it!)is 11kgs (i removed the pump and fitted a shorter aux belt - no rattling pullys now - and reduced rotating mass ) 6kgs lighter battery etc, etc
the - 155kgs increases the payload, improves MPG and reduces wear on tyres, suspension etc, the handling is transformed and it feels like a different car.
because the car is 155kgs lighter, the (stock) brakes work much better
I could take a lot more weight out, but it might affect traction, all the door cards, electric windows, trim radio, etc are still there, (remember its a "sleeper" so has to look "normal") but i plan to replace all the glass windows on the back with perspex (save about another 20kgs) (- 175kgs)
The 155kgs weight saving means it gives the equivelant power- weight ratio of a 210bhp Mk3 hatch/ saloon,(if my calculations are correct) i have a load of parts/ modifications filled, i hope to make it the fastest accelerating of its kind when im done (the in gears/ midrange is quicker than a stock st220 but not the 0-60/ 0-100/ top speed, at the moment)
ive already fitted the (elictronically controlled) electric waterpump (faster engine warm up, , less parasitic power loss, better control of temps runs independant of engine/ after shutoff if nessesary (so fan not required, again saving weight )
Im still getting 40mpg and i really enjoy driving it - it just looks like an old Mondeo estate with steel wheels (well it is) but it often puts a grin on my face in spite of (or because of) this
Keep in touch and let us know how you get on with your car/ project - very interesting!
