let me ask you again. what spark plugs are you using ?

We put stock 9's in on the dyno.....

Twin power is a amp for both trailing and leading IIrc


Read my above post, will give u some more details

Yes we are running 9's.
I will be checking the spark in 30 min as soon as i get home.
ill let you know with in an hour or two.

ok check them good. carefully look in it and see if the ceramic part is not coming out .
make sure compare with a new plug

Why are you not running 11's instead of stockers? Especially at 25 psi.

Water injection

still i wouldn't run those plugs at 25 psi. i dont care if is e85 or alcohol

if the car had an ignition issue, wouldn't it break up when under boost? it would seem like the timing is retard.

i did have spark on all 4 plugs.
also the twin power is working. i checked that too.
i can put 10's in there but i dont think that is 100 horses.

it does slightly break up under boost though.. idk there something very strange going on.

Was the spark size or color or intensity different at any location ?????it should have been noticeably larger/intense with twin power!! If it didnt the twin power may not be doing what you think! We know you have spark, if you didnt the car wouldn't run... Heat range of plugs is not the issue!

Your setup is VERY similar to mine. I'm running BW S366, streetported, 3mm RA superseals, full 4" turboback, HKS twin power, FMIC, 850 primaries/1600 secondaries, all 9's for plugs, dual nozzle water/meth injection, etc. I made 540RWHP @ 24.5 psi on pump gas, so something is obviously very wrong with your setup. Are you on stock coils? If so, my vote is for a failing leading coil. ;) Also, how old are your plug wires? Seems like your timing could be too retarded, as well. Keep in mind that you may be dealing with a combination of issues here, not just 1 problem causing 100% of your power loss.

My dyno curve can be observed by clicking the BW S366 link in my sig. :icon_tup:

BACON
yes with out the twin power i have week spark. with twin power it much better bright spark.

not necessarily ...


if afrs are good. what are your exhaust temps ???????

^My guess would be sky high. ;)

Definitely sounds like an ignition problem. Check your coils, if they turn out to be bad look into replacing them with the IGN-1A coils. They are a very powerful and inexpensive option that can be wired up as wasted spark to be run with the PFC. They eliminate the need for the twin power and the stock ignitor so that covers two other potential problem areas as well.

Post your timing map and let's look at your spit, it may be very low?!

What dual pumps are you running? Did your tuner mention anything about running out of fuel, maybe one of them is on the way out? 12.2 is a little on the lean side compared to most of the other setups I see on the forum. Also have you had a look at the condition of the turbo wheels? Is motor still in good health? Coupling leaking under boost?...
