Thoughts on Mild steeel vs stainless sound? I'm keeping this car for a long time I think.

SFA soundwise, just better quality & will last longer.

Mild steel will still outlast your ownership of the car though...

60lb is too high for my aims, and a set of the Bosch should suit and be good for fuelling from what I understand. Chatting to Simon all about it when I get my 90k service done soon, he is the one who suggested manta and it's backed up by a few others as I've read.

Have had the Nizpro cooler sitting in the closet for like 6 months now. XCAL3 for a year and a half or something?? Finally have the cash and no warranty :)

Injector sizing (42lb vs 60lb) isn't an issue when tuning at the power levels you're after Steve. Injector scaling is set in the tune & pulse widths changed to suit required fuel levels needed.

Should flog the Bosch's now while they're out of the car & just upgrade to Siemens. Will save loads of hassle & $$$ WHEN you do future upgrades!

Dean....injectors are only as good as they're tuner. The siemens 60's are a very special and almost unique injector and I question how many people even realise this. I've spent alot of time working them out and they require different scaling to what is/was conventional. For example the factory min_PW @ 14v is 1.397ms in most strategies for the stock BA/BF XR6T injector, yet the Siemens Deka 60 is 1.391 according to Ford Racing Parts.

Theoretically when you have larger injectors, they don't have to open as long to deliver the same amount of fuel that a smaller injector does. Generally the pulse width must be lowered so that the larger injectors do not stay open so long. SO the deka is ~70lb/hr and the stock injector is mostly 33.45 lb/hr (according to the pcm) yet the it's minimum pulsewidth is similar to that of stock bosch. Check out the deka 80's the minimum amount of time the injector can stay open for is 0.599ms.....way more logical compared to the deka 60's.

You can't treat a deka 60 like a bosch injector and a lot of people do. I don't disagree with you at all and injector sizing isn't an issue (he11 I use 110 lb/hr injectors lol) but the siemens 60 can be as bad as they are good because of their characteristics. Oh and these bad characteristics don't show up on the dyno and the lay person generally won't notice anything either, it's logging on the street where you're pick this up.

You reckon mild steel will outlast my ownership? Does that mean you bank on me upgrading (factory S/C V8 mmmm lol) or that the mild steel will still last aaaaaages?

Don't own the 42lbers yet so can't sell them :P

The only other injectors I was looking towards were the new ones Brendan mentioned a while back in another thread, but the 42lbers are on offer at low low prices and hard to beat :)

" I won't mod after this round is done "

Probably.

I said the same thing.....

Only advice is to do it all properly the first time and the stuff you buy now can handle future mods if need be.

Yeah I do believe in that too. With the specials on at XFT I'll see what I can get maybe injector wise.

Brendan, I will in no way disagree with what you're saying because I know the time you spend on your car with the datalogging tool. I will however say that I seen zero ill effects when they were in my F6 at the various stages of modding/power levels. They idled perfectly (loads better than my previous Nizpro redrilled sh*tters that were tuned by a Nizpro dealer), were great on cold starts every time, had awesome fuel economy with both WOT & light throttle applications, were easy to control/tune with, and seen the barge into the 10's with only a Walbro intank pump behind them!

Maybe they are no good when being used for power levels just above stock due to the fact that the minimum PW is too large, thus overfuelling for what's needed... But they were perfect for what I needed throughout the F6's life from 290ish through to 400ish :spoton:

Are you currently using ID 110lb/hr squirters?

" I won't mod after this round is done "

Probably.

:roflmbo:

You must be a very simple man Steve... Everyone says that in the beginning :omg:
