dan just so you know... i was convinced by someone that its not safe to be goin high speeds on the streets while tuning, so im in for dyno tuning also.

 

Dan

Can you give me a link to the exact spark plug youre using?

Thanks
Jehan

 

I don't have an exact link but the part number is BR10EIX just do a search on sparkplug.com

Great another car for dyno tuning. So thats what 4 or 5 for dyno tuning...I'm gonna cut it off at 5, anymore then that will be stretching the session into the night pretty good and I doubt the shop would be up for it. Last time I think they stayed untill like 12 or so to help out.

 

yup... just wanted to let you know prior to being overbooked....

but if its not possible, ill always settle for street tuning if it comes down to it, i know there are some good advantages to it also

 

Dan,

thanks.

 

Dan,

Just wondering how you picked this plug? I cant seem to tell what heat range this plug is, and the cross reference # come out to be(5716) 3#’s lower than the rx7 leadings(5719) the tailings are listed as (5720)

Dimensionally this plug seems right, Just trying t find the hear range which by the # is a 10 right?

With the new ignition set up im going to have im planing to run 11's I have a extra pack of 10's i got from Keith (Kg parts) ill bring with me just in case we need extra

 

Ignore above post, i got to stop typing b4 i have coffe

Seems like the iridium 11’ are 1RE01-34 (35.30 a piece) and the B11EGV’s (5.37) looks like the 11egv’s win LOL

Couldn’t seem to find Eix’s in colder than 10

Sorry to constantly hijack your thread

 

Fellas! Steve Kan is well worth the money. He made 533whp on my car this weekend. He turned every car he tuned into a completely different car !!!

 

Hmm... Who recommended these plugs to you? How long have you run them? I've heard more about the B11EGV plugs that Len is referring to. I guess I need to do more research before ordering.

 

are you guys just gunna use the cold plugs for tuning? or they are your everyday plugs?

 

Everyday, I plan to use them all the time, Well I also plan to run C-12/16 all the time, and run 25psi boost wherever I can

I don’t get to drive my car as much as I want but I drive it like I stole it when I do

 

LoL.

I couldnt decide so i bought a set of both the EGV's and EIX's in 10's .. We'll see which performs better with my setup during the tuning session.

Question for Len, Martin, Dan .. are you guys still running some sort of fuel pressure dampener (either stock or aftermarket) or have you completely eliminated that from your fuel system? Im debating whether or not to put one back in.

Cutting it close again. I pulled my injectors out to get cleaned and balanced. Dunno if I should go the 850cc primary route. I currently have the 550/1600cc combo on a factory port motor. What do you guys think ?

 

I was running the cheap ngk #10's from advanced auto when I made 533 this weekend.... they worked fine.

 

Lupe, are you running a fuel pressure dampener? or have you eliminated it?

 

i have aftermarket rails with a fuel pressure regulator, i dont have a dampenner anymore

 

martin, any probs with that setup ? im running the same setup at the moment.....

im on the fence on whether or not to buy a pair of marren fuel pressure dampeners ..

 

Umm, actually there was a big thread about spark plugs a while back and someone recommended using the plugs I have. Rich also has these on his car UNGAPPED and he made 426hp at 19lbs on his bnrs.

As for the fuel pulastion damper..I am running an aftermarket pulsation damper by marren it costs like $120 or so. www.injector.com has em for sale.

Alright now to the 550cc's to 850cc swap...how much pressure are you looking at running? You should be fine on those injectors if you don't plan on running more then 19-20psi

That should take care of this round of questions.

well... i've had fuel related problems but none that i know of from lack of having the dampenner.

i was looking at kgparts.com's kits and doesnt look like those have dampenners included... if you have the money, it seems good to have though

 

I figure it was put there for a reason stock, some people claim to be fine without them. I'd like to make sure the fuel flowing into the rails is straight and true without any turbulance.

 

My current set up has a home brew FPD Don’t know if my time constraints will allow fabrication one with the new setup (individual pumps and lines for each rail)
The Fpd’s purpose is to reduce the shock on the fuel system from having 60 psi flowing 1 gal a minute shut off in the blip of a throttle. Think of it this way guys have you ever been in a old house then using the sink/shower on full blast then shut it off? You get that classic “banging” of the pipes that usually scares the carp out of you if it’s late @ night.
Now to correct this problem you have a small section of pipe that goes above your last junction and is just capped b4 you turn the water on (Ernie T can give you the technical plumbing terms ) this pipe holds a small amount of air (relative to the size of the plumbing system) and allows for expansion/contraction in the varying pressure scenarios.

Now my system that is using the stock primary rail, threaded with -6 fittings is a small T right b4 the primary entrance, that goes up about 1-1/2 inches and is just capped I can still see a small amount of pulsation even with this setup but much less than without. Personally I’m a firm believer that there should be a pulsation damper, @ 80% duty cycle were flowing over 1 gal a minute, @ 100% were flowing 1.33 galons per min (850/1680cc setup) will it be ok for 10k miles, 40k miles? I don’t know. Don’t think I’ve seen like any racers with Fpd’s. What about the big v8-10 guys, vipers, C6’s Grand Nationals, do they have any fpd’s ??? I know it’s a dissimilar comparison but we’re dealing with fluid dynamics and fuel system design which still has the same basic points.

I most likely won’t have one for the tuning, but I will probably eventually install one. Now you can search and search to find info but in the end it will be like the AST debate, “Mazda put it there but do we really need it?” There are quite a few things of Mazda’s I’ve removed from my car but no one seems to know if it is really required. I know were all worried about the pulsation but most of us who are worrying are running Areoquip or similar lines, AN fittings and a full racing fuel system designed to handle more abuse than we can throw @ it.

Now off for a cup of coffe LOL

 

I run a aeromotive fuel pressure regulator. I don't have any dampners.

 

some say the aeromotive press reg. has a pulsation damper in it, but I don't see how it's possible to have a pulsation damper after the fuel rails.

P.S. Isn't this the Steve Kan tuning thread?

 

Its still the tuning thread. Just trying to get some "mini" issues taken care of before the tuning session.

On a side note, the parts I ordered are coming in tomorrow and Friday. Time to get dirty.

 

Hopefully my parts will be in this week so I can get everything worked out. I still gotta hard wire the fuel pump to the battery, but thats a minor issue.

 

I got dual pump setup, dual SX filters, New primary rail, all the fuel lines associated with this stuff, 2 crane Hi-6’s and coils. Got a busy day today And maybe the kaaz, 4.33’s and axles that are sitting in my room

lol
