finaly got a chance to have steve tune my setup this weekend and had nothing but problems , i had ignition breakup from 6500-8k starting at 13psi , the leading plugs would foul every two runs so we would have to pull them and clean them to keep going. I finaly asked steve to just turn up the boost and only brng it to 6500, we ended up making 486 whp at 32psi and 6k rpm when the clutch finally gave. im running new factory coils with a msd 6a and msd wires and that apparently isint hot enough , so im just curious as to the setups that do work on higher horse rotarys . steve recomended a turbo 2 coil or possibly ls3 coils with the 6a . i know there are tons of post on ign setups but theyre old and id like to see some real numbers with proven setups . so what ignition setups are you guys running that will support over 600whp?



street port 13b

aem ems

gt4088

msd 6a / wires

stock coils

ngk 10.5 race plugs

premix only

bosch 1680/ID1000

aeromotive A1000

-10 bulkhead in tank

-10 to -8 y for fuel rails

-6 returns of frails to fpr

stock return line to tank

Re: THE QUEST FOR 500
 

486 @ 32 psi ? wtf ? :sly: damn that sucks no offense you have some big issues
switch to another ems

Re: THE QUEST FOR 500
 

there is nothing wrong with the ems, . its not enough spark to make a complete burn . we would literally do one pull and the plugs would be dripping wet and the shop filled with black smoke. burn more fuel= more power.


no offense taken to ignorance

Re: THE QUEST FOR 500
 

o right. do you know the fuel curve might be to loaded?? thats why you are killing the plugs?? im stilll sticking to what i said. your engine power sucks ass. i mean seriously? 32psi and cnt get to 500 hp?? what an ignorant . you just got ripped off

Re: THE QUEST FOR 500
 

fuel curve ? your a moron fuel curves are different for every turbo, injectors , fuel difference map, stage flow ratio ect.... thats why you tune to a specific afr that works best with the fuel your using , mine was 12.5 due to the use of 110 and the leaner you afr the harder it is to burn . why dont you do some research before making ill informed statements. this post was started to try and find different ignition setups that are being used usefully and that was it .

Re: THE QUEST FOR 500
 

no ****?? like i didnt know that ? man go ahead and keep throwing away your money. exactly who ever is tunning gotta be real good at it. has to know how to clean the exact points. you stupid **** look at that 12.5 and still fucked up. get the **** out of here with that **** man . :jerkit: most people make more than that and with lower afrs . and a suckier ignition . so :blah::blah::blah::blah::blah: you lost your money buddy

Re: THE QUEST FOR 500
 

steve kan tuned it in san jose at tech 3's shop , if u could tell me anyone better to tune my rotary go for it :loser:

Re: THE QUEST FOR 500
 

ok for drivability i can say he is one of the top ones. cant take it from him. but for what your looking for?? and race ?? man seriously he is not . im sorry
but again you got nailed. nothing personal :la: . plus if hes familiar with that setup then im sure he knew that was going to happen but guess what ?? i dnt think he did. . if you can afford it contact oso , gaby skern or siguel . dont know about them?? then you live in a bubble . :eek4dance:

Re: THE QUEST FOR 500
 

If you want to replace the ignition I have a complete M&W ignition just sitting here.

M&W Pro-14R CDI box
M&W coils n brackets
Magnecor plug wires


Barely used

Re: THE QUEST FOR 500
 

how did they work ? i cant find any specs on them dwell , amperage rating.
what setup did u use them on ?, how much? also what plugs were u using ? i was thinking about changing to a non resistor plug

Re: THE QUEST FOR 500
 

type M&W Ignition into Google

what fuel pressure are you seeing? your post there says you use the stock fuel return line, can that keep up with an A1000 pump?

You should be able to do this with a stock ignition, you don't need mine. How old is the igniter? Has the MSD failed yet?

Re: THE QUEST FOR 500
 

hehe just like i said

Re: THE QUEST FOR 500
 

Stock ignitor , msd box seems ok , dwell set to 4 ms on coils and fuel pressure was 40 base and would rise 1/1 with boost . The stock return is large enough to keep pressure at a 1 to 1 ratio

Re: THE QUEST FOR 500
 

hey man seriously i think is the tunning are you getting steady afrs during a wot run ? i doubt it but let me know

Re: THE QUEST FOR 500
 

get over the tunning thought its not the problem , if i knew how to post pics i would post the dyno sheet . 12.5 afr from 10 psi up no dips a perfect straight line . i made 49 pulls on the dyno trying to figure out the issue and the only time i would get a clean pull is right after i would pull the pugs and clean them , i would then get 2-3 pulls before the plugs would foul again (litterally dripping wet) . i made 486 at 6000 rpm before the clutch fully slipped still had 2000-2500 more rpm to go on a weak clutch. im gonna try some different non resistor plugs tommorow ad see how that goes .

Re: THE QUEST FOR 500
 

kool check it out. will suck if you buy an expensive ass ignition system and be on the same boat.. maybe injectors staying open ?? and yes can be plugs too. not heating up what they are supposed to. are you doing quick pulls? or you let it idle a while and then do the run?

Re: THE QUEST FOR 500
 

the 1600 cc injectors are know to be a bit bi t chy so check it out

Re: THE QUEST FOR 500
 

Something is wrong besides the ignition if the 486 at 32 psi is correct? My REW did 470 at 19 psi with really fat air/fuels. I stopped at 470 actually because the MSD was starting to have issues with that power level, it developed a miss under boost that would come and go. I have since switched to a HKS twin power and it seems to pull clean. No need to go coil swapping if your coils are in decent shape, I have seen stock FD coils with ign amps go to near 700 rwhp.

Re: THE QUEST FOR 500
 

with that said , have you had issues with the ngk race plugs , it almost seemed as if the 10.5 was too cold for single runs on the leading side . the trailing side looked better but still cold ( wasent cleaning deposits).
Im going to go buy a set of br10eix's and a set of b10egv's today and se what happens

Re: THE QUEST FOR 500
 

the br10eix plugs have work for me very good, for my cars and customer cars. i also use 11.5

Re: THE QUEST FOR 500
 

I don't use the motorcycle/2 stroke plugs, I only use the NGK r6725 series rotary specific plugs, and I run 11.5's and have had no issues with fouling.

Re: THE QUEST FOR 500
 

so i rolled a set of b10egvs in the car today , every thing felt great for half the day and then it started breaking up again. I got home and pulled the plugs , the trailing looked great nice and brown the leading was black and wet with oil deposits on them as if they were still too cold of a plug on the leading side? I check the spark and it has a scary amount of it (jumping a 3-4 in gap and purple as can be ) . I run vp 110 and motul 2stroke at a 1ounce to 1 gallon ratio . WTF?

Re: THE QUEST FOR 500
 

ok them trailing is good then you still have an issue on leading?? ok well can you check the leading system? like wiring,ground, voltage drop , maybe is shutting off

Re: THE QUEST FOR 500
 

i was thoug the same thing, but why would it be fne for 10 pulls and then get worse. Im going to put a set of 9's in the leading and leave the 10s in the trailing and see what happens . there was a definet improvement going from the 10.5s to the 10's .

Re: THE QUEST FOR 500
 

Sounds like you may have unbalanced or leaking injectors.

Re: THE QUEST FOR 500
 

thats what i was thinking. check the injectors , then check the leading see whats up. also be carefull on the 9s

Re: THE QUEST FOR 500
 

to the op im sorry for being so rude at the beginning . i just cant stand when
shops etc dont inform you 100% problems you got after spending x y amount of money with them

Re: THE QUEST FOR 500
 

its all good , Im a tech at infinete velocity motorsports in reno nv. all the tuning and work was done by me prior to steve tuning it, I just wanted to see what he did with the timing maps and to get some dyno numbers. the break-up was never felt but you could see it on the dyno and the numbers werent where they should have been. thanks again for all the input .

Re: THE QUEST FOR 500
 

Peak power numbers are on the low side because hes not able to rev that high; Gt4088 is only a 63mm inducer turbo...

I agree something else is going on, and its not plug related..

Re: THE QUEST FOR 500
 

so i just called my engine builder to get a build sheet , I was under the impressionthat the engine was 700 hp capable and its got every thing there to do it except it doesnt have studs or dowels? i just started noticing a little puff of white smoke on start up . possible coolant seals hurt .

Re: THE QUEST FOR 500
 

dowel has nothing to do with the water seals.

Re: THE QUEST FOR 500
 

The builder was saying that on high boost rotarys the housings start to move around a lot , he said he could visibly see the housings chattering and the dowls worn out . He said if the housings lift it give more of a chance for exhaust gas to destroy the water seals ? I haven't had a rotary apart but I guess I will soon get the plesure of taking one apart

Re: THE QUEST FOR 500
 

ehh well you can say but im sure play on the dowel will crack the plate quick
specially you having ignition problems

Re: THE QUEST FOR 500
 

Problem solved ! I put the bur9eq's in the leading and ngk 6725's in the trailing . The car is crisper than ever and boost comes on 1000 rpm earlier.

Re: THE QUEST FOR 500
 

awesome. get it on the dyno again and see

Re: THE QUEST FOR 500
 

Updates?

Re: THE QUEST FOR 500
 

the plugs were not the cure. shortley after the car started to smoke (burning oil) what i was seeing on the plugs was oil not gas , the front rotor was worse than the rear. during the teardown there was standing oil in the #1 housing and te control ring wearing surface was almost completely shiny on the front rotor, much more than the .020 allowed . so why are they so worn? not replaced during rebuild? side plates too worn (.010 wear at the side seal wear pattern on the combustion side)? e-shaft endplay? oil contol ring clearence? I sent the side plates out to rb to get lapped and ordered a new set of control rings with seals,I plan to reassemble with the fresh housings and control rings also checking all clearences since im a little worried about the builder i chose .
