MD321T+ and 800HKS Injectors - Overkill for 400hp?
#4
Banny, Dunk
Yes I suppose so.
Its just I have them lying about in a box.
I guess I could sell them
I currently have 310hp / 365lbs and the car is bloody quick (stripped out classic)
My origonal plan was to go way over 400hp.
But I kind of have the feeling that I will be comfortable with 400hp as road and track car.
So might try and find a H and 550s I suppose

If you already have the 800's then just keep them incase you want more power in future, a mapper should be able to sort everything out regarding fuelling etc to get them running sweet.

I've got a MD321T and 740 injectors ... only pushing out 398hp, any idea why that might be (full spec can be seen on left there)? Booked in to Mocom in a few weeks to investigate

Don't worry about the size of the injectors, in regards to low speed / idle... be more concerned with the ability of the mapper and/or ECU. For information I have 1150's and mine cold starts fine, idles 100% fine and has no different low down characteristics than OE!
If you have no intention of going for 450+bhp, then it would be prudent to spec your turbo to your 400bhp goal! If you have an incling that you may want more, then go for a bigger turbo to provide you some headroom.

Running a MD321T and 650s on a 2 litre newage JDM. DD records 426bhp.
You dont say if your running a 2 litre or 2.5 or something else?
Would a T+ not be very laggy on a 2 litre non AVCS car?

Regarding 550s, I think they can max at between 390 and 420 on straight pump fuel (presumably 99?), so you could be lucky or not. Perhaps fitting an FPR will allow the mapper to run a tad more pressure, thus fuelling, so as to be able to achieve the magic 400?
As above, I'd defo sell the T+ for the H. Or even the SC40 Billet (still undergoing development though). No point in running around "un-optimsed" - i.e. spool-up and torque occurring too high in the rev range - if you have options available not to...

Thanks Simon, attached. Let me know what you think pls. BR mapped the car. 2 boost settings, 1.5bar & 1.8bar. 1.5 seems to hold fine whilst the 1.8 drops away.
BR did mention that the plugs were "misfiring" at 1.8bar & suggested changing them to race plugs. I have the plugs which Zak will change in a few weeks time. I'm a mechanical luddite so doesn't mean much to me

looking again and it isn't rich..
so issue has to be ignition or boost.. boost 1.4bar at peak.. being an obvious issue.
needs more boost.. HKS EVC VI should be capable but yes AVCR does have duty per rpm whcih helps.. but if HKS boost controller struggling then perhaps actuator is the issue
