slvr did you ever get your oil leak fixed?

 

nope taking it to Charlie (Mazcare) around the middle of June
no rush since I'm not tracking again til the fall

 

Moon thats probably a better idea than just increasing the ground wire size.
The ignition coil power wire is only a 20 gauge wire. If we are to get full benefit from stronger ignition coils then that wire is undersized. you have to get power in to get power out.
On the oem dwell table that size wire is probably fine--but your aftermarket coils are much more capable.
In the next couple weeks ( Momma is in the hospital again) I am going the Kenne Bell Boost a spark way. It comes with a hobbs switch so it will only activate when in boost. Startup/cruise etc will not be affected.
I will be increasing the sparkplug gap size afterward.
My engine seems to fall a little flat after 6K rpm--just doesnt pull as hard. That is about when the oem dwell table greatly reduces dwell. I am running pretty rich a/f's--low 11's so I think the spark could use a little help. Its worth a shot?
i started a thread in the Tech section if anyone is interested.

 

boost a spark will be here Tuesday--so harness mods and bas install next saturday. Stay tuned.

 

Are you gonna run the BAS with the MSDs? If so, have you contacted MSD techs regarding using the BAS with the MSDs?

 

nothing worse than someone who doesn't have any clue on how to handle a gun that is shooting from the hip ...

 

Team --I have handled many more firearms than you ever have. But, I think you are referring to me having a knee jerk reaction to whatever. Shouldnt assume that.

Yes I have spoken with MSD and Kenne Bell. No problem with running the boost a spark with these coils. There are multiple vettes owners using the bas unit without a problem. Many GM owners think these coils need 5-6 ms of dwell and they dont--they only need 3--so you hear stories of these coils toasting some times. If the gm guys want to run these coils they do need to turn the dwell down some. But many dont turn it down from the factory settings and they toast after a little while..
I have also spoken with Steve Kan and he doesnt see a problem either.
Its just another way of get the proper power to the coil. You can either increase the dwell or increase the voltage ( up to a point) They both also said if the primary power wire to the coil is as small as ours then up sizing is a good idea.
Now the BAS will have a hobbs switch and it will only activate at 3 psi boost not 4 as I originally thought--they changed it. Thats a good thing. So regular driving/start up is not affected. It has great pass through capability also.

According to the oem dwell table we do not have the coils full ability at 6K and beyond. At 5K it starts being reduced. That means we are getting reduced spark at the torque peak with these coils. Remember we need 3 ms.
Take a look:
voltd  1000 2000 3000 4000 5000 6000 7000 8000 9000
6.50 7.58 6.00 4.75 3.56 2.85 2.38 2.04 1.78 1.58
7.75 6.75 5.33 4.67 3.56 2.85 2.38 2.04 1.78 1.58

10.25 5.58 4.42 3.86 3.52 2.85 2.38 2.04 1.78 1.58
11.5 5.17 4.08 3.58 3.27 2.85 2.38 2.04 1.78 1.58

16.5 3.25 3.13 2.81 2.56 2.38 2.24 2.04 1.78 1.58

sorry--cant get it to space properly after copying.
So these coils can use a little help after 5K---- and I really dont understand why the dwell table at 7K and above doesnt change regardless of the voltage.
I never go into boost below 3K.
I am anticipating having to use approx 16-17 volts at 3psi/ above. If sucessful then I will try to open the sparkplug gap from the present 28 to 35. But one step at the time.
You have to also remember that lowering the harness's resistance will help a little.
I have already made my conversion harness.
capacitator can take up to 24 volts.

 

Interesting, keep us posted. You may be able to put a conversion kit together and offer it to the community

 

Very good and here is a gold star for your homework *

Now, get back to work and provide some feedback/data.

 

ROFLMAO
OD why do you even respond, always with the negative waves and rarely with the how and why. I always read his comments and ignore the negatives looking for the jewels of wisdom which we know show up from time to time.

 

Team is a smart guy and he knows a lot about this car. He may be seeing something that the rest of are not--if he is i wish he would cough it up.

 

team is usually more interested in telling us how much smarter he is than us (which I do believe he is) than actually proving it

 

I put the misses car together from all the trials and tribulations from everyone here. Ran like a top from the get go, I stole yall's hard work and it's great. Telling me I'm stoopid is something I already know, hehe, send help. LOL
OD ye never did comment on my engine boiling when the instructor lugged it and overheated my baby. I kinda know why but is always good to hear it from my betters.

 

Way back 3 yrs ago I was having missfire issues at around 320-330whp so i increased dwell on the oem coils above 5000rpm by 5-10% . Cured the misfire instantly . When i mentioned this on here it was met with the usual derision from a certain party .
Never had any issues with my oem coils either .

 

it will happen NA too if it goes pig rich in a similar scenario

however, there is no guarantee that this is the case here, he is guessing/assuming

 

you're more interested in believing and promoting stupid BS than you are in comprehending what is going on around you

the only reason he is going down this path is from the information in the dwell thread where the info was posted for his particular coils. Everything he needs is there. The problem is he always goes off on some zany, hair brained tangent with 110% conviction and can't be reasoned with.

I gave the guy a perfectly good engine for free when he was down on his luck. How much more proof do you need?

 

I just dont know what to say.

 

what happened OD?
your ideas change?

 

no.
just am getting tired of being called hopeless i guess.

 

Never give up Leatherneck

 

I think your car negates your hopelessness
pioneers may not always be right but, they arent afraid to tread new territory
thats what makes them pioneers

 

I don't promote or encourage anything in this thread, nor have I ever in any post. I am very careful to only talk about things I know about, which is not often.

You just have a ridiculous habit of insulting people who are trying to find their own way instead of throwing out some left and right limits to help them along. If I was OD I would send the engine back, because I am not sure it is worth all the **** you give him on a consistent basis for his ideas (hair brained or not). You are down right mean to the man, who is nothing if not nice and open minded to constructive criticism. Stubborn, perhaps; but berating him without any actual reasoning doesn't seem worth the one or two times you did him a favor.

How about the time you spend coming with a disparaging remark you write 2 or 3 sentences pointing to why he may be wrong. And if that feels like too much spoon feeding, just tell him he is wrong without the personal attacks.

I just don't get you team...

 

it is always going to be a good thread when someone's feelings get hurt over something said on the internet.

 

Teams not a team player. You would think since he has TeamRx8 as his SN he would be. Wish this kinda this kinda **** would go elsewhere. If people would really work together as a team with encouragement towards one another I can only imagine where this community would be.

 

appreciate the support guys.
Yea I just dont get it either. If I am wrong--thats OK--just tell me why. I don't blindly accept someone telling me I am wrong without explaination.
I feel I am not wrong in my choice of increasing the power to my coils through increased voltage versus increased dwell time. I feel that doing it this way as some advantages in my particular case. For those of you that dont know--I run the MSD 8247 coils which require only a 3 ms dwell. The oem dwell table falls short in the higher rpms for these coils. So with a hobbs switch activated at 3 psi boost this unit will put more volatge to the coils when I need it and only when I need it. The coil duty cycle will remain the same as they are now.
The coils will last longer this way also.
Although I do appreciate Team stepping up and helping me out during a bad time, he can have his engine back (and its much better than the one he gave me). Cam at Pettit racing did $3,200 of building on this engine ( worth every penny) after it was shipped to him, but its not worth feeling indebted over. So I can just build another at some point.
