What is the goal??? well if VAG 20v T's can get to 300bhp with not much in the way of major tuning then i can 't see why with alot of work, due to it being a older engine, i cant get mine to 280-300 brake.
Heres a Current pic of the car for anyone who's intrested
I'm still going to be sticking to the Superchargers and not swopping to turbos as i love the whine and the way theres instant boost with the superchargers.
So far i've been gathering a few bits togeather ready to start doing things when i take the car off the road in winter, so far ive bought two iner coolers, one saab and one Volvo type, both simular but with different porting.
Unfortunatly neither of them will be able to satnd the high boost pressure with out balloning and then blowing the end atnks off so i'm going to use them to mock up the set up and then get an ally one made to the sime size so i know it will fit in with out having to modify the carsfront pannels.
Been busy at work to making a stainless swedish style inlet plenum although it would be better made of ally i dont have access to a ally welder or ally for that matter. i'll get some pics up when i can,
I've also bought all the pullys to swop the M42 "V" belts to M43 flat belts this means if i needed to i could use the same belt to run the charger as other ancillerys, wether this is a good idea or not i dont know as least if i had two belts if the supercharger belt snapped the water pump and alternator would still be working if in needed to say limp the car to the next service station.
The two next big things to sort out are the lower compression ratio and the supercharge trim.
ive been speaking to a company called TTS performance who are the distibutor for Rotex chargers in the UK and they have suggested i go for the biggest one they do in the C30 range the -94 size as this will do 250-400 bhp range , alittle larger than the one i thought i'd need the -84 that runs 200-320bhp but the lad i spoke to seamed to realy know his product and also had good knowledge of the other kits and cars that they have charged in he past and what charger they used to get what power.
The same lad suggested i only drop the Cr to 9.5:1 as he use the same setup (-94 trim) on civics running 10:1 however to me this still seams alittle high for me as i was thinkin more along the lines of 8.5:1 however maybe the middle ground of 9:1 would be better?
think i'am going to need to be running around 20psi boost to get to 280-300bhp
Any one got anythoughts? all help and advise welcome
Cheers, Matt
which is as good if not a little better than a turbo were as my current Eaton M45 is only getting around 50-55% 
And I don't blame you mate.
and stripped the housing off the charger to rotate it as the oil in-out has to be at the top of the gearbox.
