Octane

[turbodaytona87]

Just curious what you boosted guys run as far as octane also note super/turbo charged and psi.

[Coupelx]

E85 105 octane on 8psi

[Nubraskan]

91, supercharged 7-8psi :ohnoes:

[JesterMX6]

87 - 100

7 - 20 psi turbo

[srt-4_uk]

turbo, 21psi, mid 20* timing, 93octane with no ethanol.
I also run a direct port water meth setup. 4 M1 nozzles spraying 50/50 water meth.

[DSMMIKE]

turbo 20psi 92 possibly higher boost too but mostlikely will turn the meth on for anything over 22

[turbodaytona87]

Ok just wanted to make sure I wasn't the only boosted car running premium

[JesterMX6]

no one ever said you're the only one.


but if ur really getting knock with lower grade gasoline, maybe dont give it full throttle? or turn the knob counter clockwise?

[MadmaX]

Ok just wanted to make sure I wasn't the only boosted car running premium

there shouldn't be ANY boosted cars NOT running premium. wth? where did this question/comment coming from?

[Coupelx]

i run 87-89 in the merkur...

[MadmaX]

stock non-intercooled?

[JesterMX6]

i get no knock issues running 89 on an upgraded turbo at 15psi daniel. not all cars need premium. depends alot on how they're tuned.

[MadmaX]

well sure. you can make up for it by running rich as ****. what did you just save?

[86Shelby]

89 on the omni less than 6 psi.

91 on the R/T -been up to 20psi with no knock; consistantly at 15.

[turbodaytona87]

Exactly now you see my point, I want to run 15psi(ok technically 14.7), why should I run less boost or not run WOT just to run a lower octane?

[JesterMX6]

because you'll be saving gas by a. not running WOT and runing less boost and B. being able to buy cheaper gas.

[Coupelx]

stock non-intercooled?

yup 10psi. 9* of base timing.

[turbodaytona87]

I don't run WOT all the time, but if the opportunity is there, I may want to. I don't really care about saving $0.10/gallon, if I was I would most certainly take out the boost controller, although the car is dog slow on 5-6psi.

[MadmaX]

stock non-intercooled?

yup 10psi. 9* of base timing.

it's your car. got a 1035 in there already?

[Coupelx]

no and its not needed.

many have done the same thing as i am. i also dont constantly beat the **** out of it. if your 8993 is properly installed and your car is setup correctly then i see no reason for the 1035.

[MadmaX]

of course it's not needed at so little psi, but it's like $30 more.

Do you know that you are getting knock using a lower octane?

[turbodaytona87]

No, but why chance it

[srt-4_uk]

why change what isnt broke? I would suggest finding out if you are knocking first. Then if you are not, up the timing or the boost if the a/f ratios are in check. Might as well make it faster at the same time.

werd.
thats basic modding procedure for any car imo. make sure everything is tip top,
then mod it.

[srt-4_uk]

if you really wanna up the timing/boost, I have 4 water meth nozzles and a distribution block. Direct port water meth does wonders for suppressing knock. All you would need is a pump, tank, relays and a checkvalve.

[turbodaytona87]

Well until I find out if its knocking, I'm not going to take the chance so I'll run premium. I mean its already running two degrees more of initial timing and 2.7 psi more with a quick spool. I get part throttle boost already so I am sure premium helps with keeping knock down when that happens

[CrazyPete]

22 psi 105-108 octane

[turbodaytona87]

I have a new ecu chip coming that will let me run 20psi, that's about the limit of my block anyway.

will you be able to tune the chip or get it re-burned? most mail order tunes are so conservative, they are almost worthless. I personally would invest in a nice wideband and something to read knock. Then make the adjustments yourself because even after this chip, you still dont know whether you are knocking or if you a/f ratios are in check. It will also set you up for down the road when you get tired of 20psi and want to throw in a t3/t4

Na! Mine saw 32+psi. The stock pistons on the other hand is a different story:)

My .02 is METHANOL INJECTION!!!!. or E-85. I have been at 32+ with a t3/t4 with premium and methanol on an 8v TD.

[turbodaytona87]

Chad I have a non common block(started building before I knew better)

SRT-4 it is kind of mail order, but its done by a guy that has an automatic TI Daytona in the 13's, I am sure he knows what he's doing, he asked for injector size, engine size, ported or not, etc. I can always download the free D-Cal and adjust settings if I need to. A JAW is on my list of things to buy before I put in the new cal, I just bought my 3 bar, so I need injectors and an AFPR.

Forgot to mention, the new cal will flash the Power Loss Light everytime it detects knock

[srt-4_uk]

That is good that you can make changes to it. I understand that you tuner will know what he is doing but it will be tuned to the safe side that way it cant be said his unsafe tune caused you to blow the motor. That is just how every mail tune is. The knock light is a good feature tho. Just dont make any adjustments without a wideband.

[turbodaytona87]

Ordered the wideband today :)

[srt-4_uk]

:woot:

[turbodaytona87]

Yeah I am kind of excited to see what I am sitting at, because my narrowband(yes I know) shows no lights unless I am wot and it smells really rich, like burns my eyes if I am sitting still

[Coupelx]

what one?

[srt-4_uk]

I hope it is an LC-1

Yes I know it needs a sensor which will be ordered in the next couple of days:

ROFL, is this some big accomplishment that the guy established so everyone looks up to him and buys ECUs from him now, 13s :rofl:

No I was just stating its not from some guy who found a tune and the internet and is reselling it, I was trying to establish that he's an enthusiast and from the info he wanted to know, it should be slightly better than a mail order.

[89fox]

Im not boostin but if i do boost my car ill pry be runin 93 or higher.

let me know how it works. ive heard they are kinda jumpy. i want to get a wideband for the merkur but am not ready to drop the money on an aem like i did for the 5.0.

I'll let you know, you adjust the refresh rate of the display so it can update as fast/slow as you want

[srt-4_uk]

get an LC-1 and a VEI display. You can get the LC-1 for $150 is you shop around and the gauge is $80. It isnt that much money considering it is one of, if not the most, important gauges you will need.

[turbodaytona87]

Can it datalog against rpms?

[srt-4_uk]

dont know. I haven't messed with the software

[Coupelx]

the lc1 cannot datalog rpms what what i have read.
