anyone running 800cc injectors at 400+bhp??
will there be running/mapping issues on ecutek software. car is jdm sti '03

 

Bit overkill for 400bhp but dont think there will be an issue

 

I ran 850cc on the std ecu up to 545bhp so no real issues on mine.

.. or at least none with the injectors - there will be complications that your mapper will need to get around but it is no problem.

 

im running them as i dont like running injectors near there max duty mainly piece of mind lol

 

thanks duncan

 

what power is your engine running?

 

you may get slight hesitation at low revs,i believe its best to get what you need and dont just go bigger cos you can. Ask your mapper he will give you the best advice.Ive ended up going down to 650's just to smooth things out a bit at lower revs.

 

As long as they are decent injectors then no issue at all.

 

What make injectors do you recomend.

 

Power enterprize work well.
Or modified ones like Lateral Performance Ltd | Home sell

 

Any opinions on denso,
i only ask because i just had new denso 720's in and they had slight hesitation problems if you accelerated quickly from basically tickover,Despite bob doing everything he could.Dont get me wrong it wasnt that bad but it could be better.Anyway the guy who sold me them (tlf performance) said send them back and he is sending me the 650's,if this doesnt help i will go for the power enterprize ones once i have the cash.

 

Denso's phase one injectors were fooking awful. Don't know if they've got better.

I had phase 2 740 Nismo injectors at 360bhp and they were superb. No hesitation no lumpiness and better fuel economy (off boost) than the stock 440's

 

They will be Roger Clark Motorsport supplied.

 

he has a newage car Daz so top feed injectors..

the denso's a pretty good as top feed. Don't think Nismo make top feed but I could be wrong. Also I think Nismo are rebadged Denso's.. but then I just map cars with them on, I don't fit many.

not seen an issue with them, should be spot on

 

These are what i had any opinions welcome as its these in 650 that are on the way.
