ash p Posted April 12, 2014 Author Posted April 12, 2014 Thats a nice build whats he done with his ignition leads never seen them like that before? Quote
ash p Posted April 12, 2014 Author Posted April 12, 2014 Ive even thought of going 9:5:1 I think wickedep have run a few starlets of that compression but dont know how much boost you would be able to get through that Quote
chrisp96 Posted April 12, 2014 Posted April 12, 2014 I did a compression test on my 4efe and got these resultscyl1: 210psicyl2: 220psicyl3: 210psicyl4: 215psi is that quite good or? Quote
Flaminsam Posted April 12, 2014 Posted April 12, 2014 but there wont be any mappers on this side of the pond smart enough to do so ha ha lets take a quick ferry ride ha haRdt.tv maps these most of the time. Quote
AdamB Posted April 13, 2014 Posted April 13, 2014 Thats a nice build whats he done with his ignition leads never seen them like that before? He's using CDI ignition system with 4 coils. Ive even thought of going 9:5:1 I think wickedep have run a few starlets of that compression but dont know how much boost you would be able to get through that It depends how efficient your turbo and intercooler are, you'll probably find that on something like a td04 you'll get a fair amount of knock at 1.4 bar because it will start becoming a hair dryer. On a GT28 or GT30 2 bar would be possible with a good map. Quote
ash p Posted April 14, 2014 Author Posted April 14, 2014 Whats the advantage of using a ignition system like that and where would you get one Quote
maddox710 Posted April 14, 2014 Posted April 14, 2014 Whats the advantage of using a ignition system like that and where would you get one The advantages are that you can run high compression and get very good tunablity out of it. You can't buy a system of the shelf like this. It will be bespoke (custom) jobby Quote
ash p Posted April 14, 2014 Author Posted April 14, 2014 Something that I will need then lol anyother ways of having the same setup using corolla parts or any other car Quote
AdamB Posted April 14, 2014 Posted April 14, 2014 (edited) The advantage with CDI is that you don't have to wait for a coil to charge, all the charge is stored in a capacitor, which can then be discharged by just an on/off switch. Downsides are that its pretty costly requiring a standalone engine management system and a seperate CDI module, it also chews through spark plugs. You don't need to touch the ignition system unless your going for 1.7 bar or more on something like a td05 or bigger, or around the 370bhp mark.Theres literally no reason why a road car needs to run CDI ignition, it was only developed for race engines which use compression ratios of like 13:1 and up.

neilsmith Posted May 9, 2014 Posted May 9, 2014 I've got a high compression forged 5e for sale pm me if your interestedRegards Neil Quote
Flaminsam Posted May 9, 2014 Posted May 9, 2014 Where are they based mateThey are based near Doncaster, Yorkshire. It's the same company that tuned robH's car and john pattisons. He also mapped Simon veals stock sleeved b16 turbo eg drag car. Quote
