How many of you guys are using 380 injectors with a stock map.
and if so how long have you had them installed.

 

I will be. I just received my injectors a few days ago. Gonna probably install this weekend. A few people here have been running the JCW injectors for a bit without a tune and haven't reported any problems soooo......why not? 1 less thing to worry about for me

 

You will have no problems running these injectors......but you will notice no gain at all. Only way to get any performance from them is to have a tune done that will use them.

 

Some folks have reported a modest gain by running these injectors with the JCW ECU flash from the dealer... but BigShot is right... with the stock map, you will get no benefit. The cars run rich already.... what do you think the result of adding MORE fuel will be?

 

I ran 380 injectors with a JCW flash and didn't feel a thing (heartless bastard that I am...) But the love appeared after a custom dyno tune!

 

Darn you, for crushing everyone's dreams!

 

 

the reason I asked about the injectors is because I use a superchips bluefin map and has caused problems in some cars running lean. so I could add the injectors to solve the chance of going lean or run the 380injectors with the stock map.

 

I am going to the 380s because I am getting, or going to, go lean when I install the Newman camshaft.. I was told by the guys in the UK and Eu. that it will help on the stock map.. however they suggest the JCW if you can..

There is a EBAY site selling the 380s for $220.00 search them out!!

Just me.......................

thanks ordered them two days ago from ebay

 

I'm going with JCW 380cc injectors finally to augment the years old JCW flash.

I just changed my fuel filter(just under 50K miles) and it was as dirty as a pig in a mudhole during a rainstorm! I figured it would be nice to start fresh again!

Anybody tried these single stream(4 holed nozzle) Bosch Generation III injectors before??? They've got 450's and 550's too.

srt4 injectors fit with a jumper harness. 465cc

 

Too much. i know a guy ( hes on here from time to time ) whos car caught fire more than once from using giant injectors. the cats were actually igniting. be careful

 

Shouldn't you only get bigger injectors when you have a aftermarket head or a aftermarket cam?

 

short answer no.
JCW vehicles come only with a 11% reduction supercharger pulley, JCW software, and air box and they come with 380 injectors as opposed to the 310s regular cooper s comes with. obviously BMW saw that the stock injectors were maxed out on duty cycle as it was.
So with a 15% pulley and a moderate tune should warrant the need for 380s along with colder plugs.

 

i have the cam of many names in without any issues.

the jcw 380's are on the shelf waiting for the man to come out east...then i'll pop 'em in.

 

damn...never heard of anything like that happening. a know tuner uses these injectors so i find that odd. Long as there tuned right i cant see the car catching on fire. Sounds like something else was wrong with that car

 

Unless the OP has some other mods....... injectors will get him no additional power/performance.

And I would get rid of the superchips map......bad juju there.

 

the mods I have are 15% pulley/superchips bluefin map/janspeed header/ngks/quicksilver exhaust/grs intercooler/ddm caI/occ

 

I use 550cc Bosch injectors (not the ones listed in the eBay link b/c mine require connector adapters) on my stock 06 MCS; with the 15% pulley, "one-ball" exhaust and a custom tune, i'm at 205whp/170wtqe on 15psi. Stock was 171whp/149wtqe

The bigger injectors can work with a stock car as long as they are 'scaled' accordingly...

 

Why did you go for 550cc injectors off the bat? Wouldn't 380-450 suffice for now?

Have you tried tuning any of the injectors below Mike? I think they are short enough for the MCS. Thanks.

Jeremy, good question. The reasons why we selected the Bosch injectors are due to cost and efficiency.

The price difference between the 380cc, 440cc and 550cc are virtually none. So for the same price, why not get the most out of them, right? the 380cc are bigger than the stock 330/340cc, but the difference is not that significant enough to make a big difference on WOT. The 440cc are good, but not quite versatile enough for all the things that we want it to do (i.e. turbo upgrade or E85 conversion). The 550cc are kinda in the happy medium where they are big enough to handle almost anything you throw at it but still not too big to control. We have tuned a few 440cc RC injectors and they were not consistent in performance. All those customers have upgraded to the 550cc and yielded great results.

On a Stage I upgrade (intake, exhaust, 15% pulley), a typical S should be pushing the 200whp mark. At this power level, the stock injectors are pretty much maxxed out and they are working overtime to keep up with the motor.
With the 550cc, the injectors are not working nearly as hard at that power level; at the same time, it can still accommodate more power should the customer decide to add a cam or upgraded IC.

In some areas where E85 are available, one can also convert their MCS to run on it. But to do so, it requires a lot more fuel.. and the 550cc is big enough to handle that as well. The bosch are quality injectors and they are very precise. We can control these a lot better than the RC's.

We can tune the 380cc, 440cc or 550cc injectors, np. And our remote tuning software will be able to provide custom mappings for the injector size of your choice. We just tuned one MCS with Newman Cam, RMW header, 15% +2% crank running on 380cc JCW... it made a little over 220whp but the injectors are pretty maxxed :(... it's also boosting over 16psi and hitting fuel cut so we are looking into a voltage clamp to eliminate that factor.

But all in all, for the price and versatility, the 550cc Bosch are hard to beat. I'm getting a set of these "drop-in" 550cc bosch injectors and test them out and see how they compare to the ones we are using right now (which require the EV6 to EV1 adapter).

Feel free to PM or post here for any questions that you may have. I'll be happy to answer them or at least point u in the right direction

cheers.

Thanks for the post Mike. I understand your reasoning much better now.

I finally ordered some JCW 380cc's to be on safe side if I track the MINI this summer.

I'd really like to see how the A/F ratios are with and without these new injectors, but I'm probably just going to put them in when I see them in my hands.

Either way it'll go on a Mustang dyno-with the 380cc-in town to see how the motor is functioning. After that a tune will be in order; providing the economy is kind to me.

I didn't realize you had remote tuning capabilities. I've read that RMW is getting close to finalizing their remote tuning option.

ALL I asked is can i use the 380s with the mods I have installed.

 

yes!
