Spark Plugs for MAD EFI System 2.5 260(245)carb motor

[Way2slow on H2O]

Lil info fer ya.....I don't know what injector ya gunna use, but after a lil conversation with Tony, I used tha XRI injectors...Tha XRI pulses are for front reed operation and tha 260 injectors are for crankcase operation...I wuz gunna use 260 injectors kuz I figger'd they flow'd more tha stock fish'in 200 xri injectors...WRONG!!......I use'd tha XRI injectors, wit a PCU on my lil bote(steel bo drag) and I have not "Tuned" it for all out top end(it will only turn 10.500, and iz pig fat over 9500)...

I don't know what control unit ya have, but fer me, dump'in tha simple digitol eloctroniks and goin to tha PCU wuz tha bess thang ta do...But thats juss my opinion

The PCU is hard to beat, that's why I have 3 . Jay bought his SDS as a package deal and that's what he has to work with. And yes, the XRI injectors work very well as well as the new style injectors But don't kick the SDS to the curb just yet It is tunable and with a lil knowledge and patience, it'll be screaming like a "tuned" PCU

The MAD is also universal for any injector, whether it be Bosch, Ford, Chevy, Mopar, BMW, Volkswagen, etc, so the sky is the limit. The SDS is for high imp. or low imp. injectors therefore any injector can be used.

the best thing to do is to use resister plugs. what hapened withus ,during break in our jaguar with a 260 efi, it would shut off. radio interference. we put resister plugs in it never hapened again

I like the denso iwf27 plug, it outlasts the NGK
The best box still is the programmed merc 849 box..... the new one is even better. Without going to a real fuel management system.
Charger, tune your motor buy sound first, start real fat. As you clean the motor up driving along you will hear it stop 4 stroking.
Here is damn close to the max power you will make, remember lean is NOT mean.

Thanks RBT.

She is comen with the total control efi computer system, so i will have all the tune ability i could ever need, mind you i doubt i will ever use it to its full potential.

Your right it will be a big improvement on power. I was thinkn about re powering, but i am happy and familiur with my motor and didnt want to get myself into something new which could give me big problems. Plus this will be more power then the charger really needs, but it will be a fun summer o testing n getting this thing dialed in.

you know if there is an eqeuvelent with 3/4" reach for my removable chamber Rivers?
thanks

[RBT]

Ya IW27 is the part number

So those brain gieger tech machine heads would use a different plug than mercury heads

[Markus]

thanks jay ill give the BR8HS a try

That's the one to get. Or the 9 if you run high compression.

You can get them made with either 1/2 or 3/4 reach, I like the longer reach for some reasons and the shorter for other.. pick your poison.

You talking about the head chambers or the plugs. Im ordering a set For drag racing whats best?

[RBT]

reach, will not effect the chamber design

thanks Rob
so does brain Gieger Tech make the chamber inserts for the Rivers heads?
just curious if thats what i got?these are around 170PSI cranking on my drag,rumor is they came from you last spring/summer...

[RBT]

Yes Bryan, can make chambers for the rivers heads. His heads are based on the Rivers, with some changes. The chambers or heads could have come from me. I had a few sets of River heads over the years.
