It's an animal! Lol

Plenty videos on YouTube if you search for Cyborg R 1.8

I love the sound of it and the throttle response is instant

Running on 390cc injectors don't need any bigger

Dyno sheet? or it didn't happen.

lol.

No I didn't say it's pointless, I said it's pointless if the ram tubes aren't long enough, there's not enough space to make them the ideal length.The losses at low RPMs won't make up for the gains up top.

It hasn't lost anything down low lol

Its gained across the full margin. Throttle response is a lot better than stock.

Will try get pics up of old sheet and new later but having difficulty getting pics to work on here. :/ keeps saying too many pixels :/

Will just link it to my photobucket if the above pics are working.

Main thing is the trumpet sizes, there ideal size for torque etc all across the board. Any bigger I'd sacrifice low end and be more mid range/top end

But atm its hard to get a decent pull off without either spinning the wheels or kangarooing as it has a harsh clutch so needs some revs to launch. So having my launch control turned on once I've finished next engine.

Wanted to make sure I could get ITB's running perfectly now I can get the high comp pistons and cams on the go

Hi, Just interested in know where you got the it's from???. NIce car by the way keep up the good work?

Cheers mate. They were originally made by a company called Harry hockley motorsport for a proton rally car. They don't make them anymore I believe but may make you some if you ask

Yeah i have asked them, but they said they don't do them. Thanks

Hockleys built the works GpA and S1600 Protons but they have farmed the engine work out to a few different people over time.

John Beattie at RED did some and Bill Faulkner - might be worth trying them

Also you don't have to stick to gen1 ITB's (that's if you are gen1). As my ITB's are actually for a gen2 but there exactly the same inlets so bolts on no problem

Also Jenvey make them for the proton satria gti so you can also use them
