Hi Turbotoaster. I've read the majority of this thread. Sorry to see it got a bit heated earlier on and glad to see it is back on topic now. I look forward to reading the updates. Maybe each time you post an update you could put a big "UPDATE" in bold, large, red text or something? That way for those of us that don't have quite the time to read all of the thread and other silly posts, we can quickly zap to each update? I wish you luck. I hope you get it done before Autumn though.
To be fair, watching everyone get heated made me laugh quite a lot, seems theres a lot of in-fighting on the forum, i dont really know what they were argueing about though, im just looking to share and offer/recieve info.
Does anyone know how to change the title of the thread so that each time i get parts/work done? If this makes it easier for the subscribers.
Another update is ive changed my injector setup to try and give me a more reliable setup, make mapping easier and save some money
There was a few issues with my original idea which i did not foresee.
One was that the additional 1600cc injectors are low impediance which means i would have to install resistors before the injectors, i knew of this and didnt think that was a big deal.
I assumed that would make them act like high imp ones, and my apexi ecu would control them as such(thats normally true) i was gonna trick my ecu into thinking that each injector was infact 2450cc(1600cc+my original 850cc) so that they fire together, the issue is the ecu will end up messing up the transition from small primary 550cc to the 2 big ones and flood the engine.
I have now solved this problem by coming across 'injector dynamics' 2000cc injectors, they are special injectors that even when the fuel pressure is increased they provide a consistant spray pattern.
by running these at 50psi base pressure they will provide 2500cc each which as i need 6000cc and i have 1000cc in primarys in the car this will be perfect.
the other benefit is i now dont need to by injector holders to weld into my upper inlet manifold which saves me money, the injectors are more expensive thant he 1600cc, but i think its work it for simplicity.
So i ordered them last night from america so id imagine they will be here sometime next week.
Unfortuately i cant get it done quicker than autumn as i physically cant get the money quick enough, if someone lent me £3k now id have the car complete for march
Wow, an amazing thread (how did I not see it before!?)
Some great technical info, and I'm going to be really interested to see you bring it in at budget (and hope you won't go over budget).
When you do the run, you'll need to get some cameras set up in the car, too!
Im sure the magazine will bring loads of cameras and there will be a few people to film it with there phones.
In terms of budget its all about adjusting and adapting to meet it, i know i can do it as there are places i can save and then places where its expensive, just a matter of being patient
Apologies if i've missed this, but where are you looking at doing the run?
M25 at 4am?
Ill be doing a few tests on 'private' test track before the event to make sure everything is working as it should, though cant quote exact speeds that will be hit
