Well, theres alot of options that you guys are trying wich sounds promissing, theres more then one way to skin a cat if you know what I meen. I was looking at a set of BMW coils that ive happened to aquire, I have more on hand if anyone wants to try them??? 3 wire coil plugs and I can also come up with the harness. Im not an electrical geniass but if you guys want to do the math on if there worth trying. You now whats funny, I have coils on my jetski that are half the size and work under boost, it tack 8,000 and there half the size. I have the ones on my truck, they seem to be pretty heavy duty but you never now till you try.

BIG and maybe an added on or 2.

A plug in and go play; nice.

I wonder how much amperage the stock ECU can handle on the coil outputs.
I have seen a Chrysler electronic ignition box melt the rubber off the back when I swapped a stock coil for an Accel Monster coil.

Leave the primaries alone (at 290cc) for drivability and then put 730cc in the secondary and primary 2 positions.
That gives you 3500cc of fuel flow, which is about 410 crank HP (assuming only 80% duty cycle and a BSFC of .65 or so).
That's what I run.

They won't "drop in".
The dwell is different than the Mazda coils and the trigger value is different.
Been there, done that.

yukons--go on today---had to make a new type of mount since they bolt on differently. from what i understand the dwell on the yukons/ls2's are ok for our system. Whatever coils/ignition package is used dont forget good grounds(mm--i know--i know--
dont also forget to re-gap your plugs to 40 You want to use that power dont ya?

MM with that size of fuel delivery you are still able to use the oem fuel system(pump etc) OK? Have you ever data logged any fuel pressure readings?
with just the increase to the blues in the secondarys the "left over" volume the pump has going to the can is minimal.

Moon put the water cooler in the back of the car then use the long hoses to increase cooling time//volume. The summit cooler I am running for the secondary radiator is low cost and very efficient--i like the single cooler concept--less pluming etc.

1) "Re-gapping" the proper OE plugs is not possible. Stop using the "beam" type plugs. Their shrapnel potential is significant.
2) The OE pump will make 400+ HP when it works.
3) I have already established the GM coil thing. Did that in February. They provide more than enough spark energy (at the correct dwell) to blast through just about any charge density at the OE plug gap.

MM --know you like the 7's type plugs--and they do OK. I just like those overly expensive rip off ngk's
with the oem ignition we have been gapping at 30.
It would be wise to keep an eye on the fuel system. we have a 255 pump (at 45psi) but we are as you know running a little higher than that. plus we have a 5/16 line. It should be fine--but with the amount of wrench time and money we have put in these cars --i would recommend an external filter assembly---leave the rest of it alone--unless you track often then 2 little trapdoors will not hurt.
appreciate your thread of the fuel injectors--- we are using (with the blues at wot/100% duty cycle) approx 44 ccs of fuel per second.

raining for 2 days and after reporting to work yesterday and being asked"what are you doing her----youre off!!" i decided to do something i have been wanting to do.
since all the "airbox" stuff is out due to installing my coils--- i modified the REVI intake box to fir our system. Not hard to do.
Just rip it to make a lid--remove most of the back panel--drill a second mounting bolt hole,--remove most of the front air intake channel thing--make a ignition coil mount--then use whatever fasteners you want to use to install the top and ta-da!!
The coolant tank fits better(more panel to bolt on to), no problem with filter etc
will post pics sometime!!

Hey Denny, when are you gona try that intake??

hey guys and gals,
first pics of my SC, not cleaned up but still pretty clean,,,,

verrrry nice Greg!!!....

a proud owner, i see

Where can i get those fuel injectors??

I have a bunch of them here.

dude you powder coated the TB and alternator? Pretty sweet,
Nice set up.
Moon --you mean the one I smoothed out/made lighter and wielded the vdi up?
He--he well --after Christmas ---probably I got a feeling it may be just a little surprise.
I will probably do it when I install the blues.
SKinka baby--may send tonight!

did this work?

Moon Assad

OOOOO, explain further!!! I was looking at one the other day and was woundering why not remove that upper section and VDI, would make a little plennim for increased flow.

olddragger

iTrader: (3)

Moon--you never saw the pics off that intake i did?
See if I can find it.
That dang thing is made of some thick aluminum---what I did was
1- removed about 2lbs pounds of it!
2- polished it---puuurrdy
3- the big port (where upper meets lower) has a number of ridges in it and the vdi does NOT completely seal when closed---so I smoothed all the ridges out and epoxied the vdi closed and smoothed all of that---looks like a trick flow intake job
While I was smoothing this out I remembered the old funnel theory and did what I could being careful to not get the radius's to extreme. I think it turned out well.
There is some small stuff that I did to the secondaries and the apv (the pipes in that set up can use a little work--if you know what I mean)
4- drilled out some of the castings to vent it just a little more.
5- the reverse side of the vdi that faces the passenger side front fender? ground it almost flat so an ID badge could be placed! The other side of the vdi is now just a flat plate(remember the vdi is now sealed internally) and that cleans up around the fuel injectors nicely.
I do need to try that thing out.

so what kind of AFRs are you getting with the revi then?

olddragger

iTrader: (3)

i wasnt clear--sorry about that---i only used the Revi box--nothing else. I like the clean look.

^ why just the box? Why not the whole unit?

Damn Denny...that is one dirty filter...how long was that in the car?? I have a 2 YO filter that is almost perfectly clean........

That is why I am using the stock box RB Revi should fit in nicely as well.
