Took some time out last week from work and managed to take my 300 to Bristol to see Jimmer of PowerZed

 

The plan was to try and get a bit more horse power out of the old lady as she was mostly stock when it came to the internals,

 

Jimmer fitted the Greddy EBC and removed the ECU and put in a new one with a map for stage 1, the car now feels a lot more responsive and boosts up to 13.3 psi the horsepower gains where tangible with around 350-380bhp expected (will dyno her at some point in the future to find out).

 

Next on the list of modifications will be a sports clutch and flywheel most probably towards the end of the year as well as brake pads,

 

I must say I found Jimmer to be an incredible specialist and a true gentleman, I can’t wait to take the car back to him once again in the near future,

 

If you replace the injectors for 740cc NISMO, you’ll be able to crank up the boost to around 17PSi which utterly transforms the car, more noticeable than the jump from stock boost to 1 bar.

 

Jimmer is the only person I’ll have work on my car’s mechanicals - been using him for nigh on 15 years. :)

740cc NISMO Injectors and 17psi? wont this simply blow the stock turbos and the engine?

With the corresponding map, no.

I think 350-380 Bhp is plenty for me at the moment but in the future Injectors and Biger turbos + map would deliver much bigger gains I'm sure, will probably need bigger breaks too and better clutch,

Your implication is that you need to upgrade your injectiors for 16 psi. This isn’t correct. Furthermore without detail it may appear to the op that he requires not 555 which are actually 615 but 740s to achieve that. I realise you chose to install 740s for your own personal reasons but they aren’t required, 740s have enough head room for over 700 fly wheel horse on 95 Ron.

 

All that’s required for 16psi is a good map and healthy system with some minor bolt ons, which will dyno at roughly 360-370fwhp. Currently he’s probably pushing about 330ish. Stock injectors are safe at this level and the real risk is preignition from excessive temperature or poor timing on the map. The majority of engine failures are map and supporting equipment related.

Your at a good stage, pushing past where you are complicates things.

Yes, they're safe at this level with what he's currently running, there's absolutely nothing above suggesting otherwise? I ran this performance for years.

 

As for your other point, I don't believe there's any implication, there's a suggestion and it wasn't for 16PSi either, it was for 17PSi. At 15PSi, you're approaching max duty cycle on 370cc injectors. 740s are a great future-proof, they're also ethanol compliant and barely anymore than 615cc.

Definitely a better clutch, your stock one will probably give out pretty quickly unless you're light with it. ;)

I’m not going to waste my time arguing with your Simon, certainly not on some pedantic level of one 1 psi, you know for well the point I’m making. Fact remains it’s safe to run 15-17, damn probably 19 psi on stock 370cc injectors with an appropriate map. Heat from the stock Turbos is the limiting factor. How much PSI your running is not a direct correlation to BHP. Go do some calculations on the volume of fuel required and the volume the injectors can supply. If what you were saying was true, I wouldn’t of being pulling AFRs in the 10s at 18psi to start with.

Enjoy driving around with injectors running at about 30% duty at WOT. At least you can be an internet hero and tell everyone what you’ve brought.

Pedantic? Oh the irony Stephen! I don't know quite what you've turned into since you had a child, you used to be a blast on here. Now all you do is come on here and bitch at Jeff.

 

The fact of the matter is, that 370cc injectors are at their max duty cycle at around 15-16PSi on stock turbos, no changing of fuel maps is going to either increase their longevity/reliability or flow at those high duty levels. They're a big part of the weak point and it's well documented, why risk it, especially on old unreliable injectors. Yes, I will carry on running my unstressed injectors with plenty of margin for future upgrades that cost very little more than the 615cc ones and would be infinitely less stressed than running 25-30 year old unreliable pintle-style injectors at 15+PSi. :rolleyes:

 

You took my first post entirely out of context as you seem to do with a lot of people's on here lately it would seem.

 

Jesus wept man, go eat pizza or something and wind your neck in.

Maybe it’s jyst allowed me to view the world in a different way, step out from the echo chamber and see a few things with more clarity. On the subject of what I’ve become need I remind you how this club has previously banned you for your antics and attitude. It wasn’t that long ago you had to beg to come back after upsetting so many members. As per usual your confusing your opinions with facts.

Wow, you bring that up too. Big man huh. Yes, I was a shite in my 20s and early 30s, I'll freely admit that, but if you want to keep digging in the past.... :rolleyes: I think you'll find I was banned nearly a decade ago.

 

Shame, the old Stephen was a good laugh and was great fun to have on the forum.

It’s not a case of big man, it’s a case of history. In fact maybe your just more subtle at it these days, I have no doubt you’ll be slagging me off later for daring to having an opinion different to your own. I’ve stood your corner on numerous occasions over the years but you don’t make it easy.

What exactly are you trying do/prove/say now? All seems a little lost....?

I would like to run an EBC. I’ve had one on a previous car and loved the ability to monitor boost and the changing numbers when the weather changed. My main issue with fitting one to the 300 is mounting it in a subtle position. If anyone has some smart ideas please show them off.

What exactly are you trying do/prove/say now? All seems a little lost....?

 

I started by expressing the case that I believe you were stating it was necessary to fit 740cc injectors to run 17 psi on stock Turbos. This isn’t a fact. You stated that was ok to run upto 15 and then your at max duty cycle. Not the case.

I called you a pedant because you made a point over a 1 psi difference. You pulled the, you’ve changed since you had a child card. I pointed out your hardly one to talk about people’s attitudes. Then edited your post to point out you were banned 10 years a go, which may be the truth but it’s probably a mere five since you begged to return after spending your time slagging the club off on a break away forum. Lots of people have and have had a problem with you Simon, your well aware of it and I’ve defended you in the past saying you’ve changed and he’s not like that in real life he just comes across badly sometimes but I’m feeling less and less that’s the case.

Does that about cover it?

No, yet again and I'll state, you read my first post out of context which is where all this merry bullshit has come from. I have not said anywhere that he NEEDS to fit those particular injectors - I have suggested that fitting them and putting the boost up to 17PSi would give you noticeably more gains. You then took that completely out of context and used it as a stage for your own tirade against me dredging up the past.

 

Why are you going down this route?

As for the rest of your nonsense, I did not 'beg' to come back on, where did this word come from? Someone suggested I re-apply after a change in the banning status of former members and didn't expect to get re-admitted, however I did. I did not spend my time slagging the 'club' off, merely a few of the old committee who have now since gone.

Ok, I've re-read my first post, I can see how you took it out of context, but you still took it out of context. I wouldn't run what I run on stock injectors, no way in hell.

There’s the point of contention. I’m saying he doesn’t need bigger injectors for 17 psi to be safe, just a suitable map, you believe that stock injectors cannot supply enough fuel for that boost level. Am I interpreting our difference incorrectly?

Inflammatory wording by myself admittedly but not a fabrication.

Ive got one in my glove box, its such an unhelpful place ive never looked at it. I sometimes think i should see what it shows and learn what it does, but then i forget its there again
