Enuff_Said

either some one fucked up your tune or your fuel injectors are FUBAR. What are your IDC's?

you heat soaked? you could probably use exhaust upgrades if you don't already have them

SSSCEnthusiast

Heat soaked as HELL and it was 98 degrees out.

Normal numbers for a stock car...

ralliartist

revs out to far to be stock, and the peak numbers seem a bit short of where they should be.

yea but with the intense stage 3..its your tune..

slowswap

Nice chunk of run 1 is missing.

My mods are in my sig, and its custom tuned.

BriantheLion26

From what i can see we have similar mods, 60s, 2.8, methanol. I put down 258/243 on a dynojet with 15% load. Who tuned it? AFR and timing?

SSSCEnthusiast

Guy said this was an inertia dyno, so idk what the load was.

Chris Dembowski (streetdreamz) tuned it, 12.5, 12* timing advance I think.

ralliartist

wow, your timing is low, that's the explanation for the craptastic numbers. advance the timing till you see some knock and then back it off 1 degrees. With methanol, you should be able to get over 20 degrees advanced easy.

slowswap

Streetdreamz? lol. 12.5 is to lean. 12.0 would be the highest I'd shoot for. Mid 11's would be a lot more ideal.

He pulled timing to get rid of knock at 12.5 afr. If he would have went for 11.5 afr, he could have ran more timing and got better number because the timing is making up for the slower burn speed of the air/fuel mixture being richer.

ralliartist

12.5 is good for the most power, might even be able to go a tad leaner, but at the same time, it's definitely not a safe tune. The low timing advance is the reason for the low numbers though.

slowswap

These motors seem to more prone to knock due to the heaton. A richer air/fuel would allow more timing making better numbers.

ralliartist

true, but he is using water/meth injection, which usually allows for max timing and a lean afr due to a higher octane and the cooling.

slowswap

Meth is a band aid fix to a bigger problem. Most tuners won't tune cars on meth because of what can happen if the meth runs out.

SSSCEnthusiast

Im running straight ethanol. No water in it.

ralliartist

that's your opinion. I know tons of tuners around here, only a few don't like meth. The rest all use it.

methanol isn't a band-aid, or atleast it isnt supposed to be used as one. its an efficient cooling tool and if tuned properly, can yield decent power increases. I have tuned several SS/SC on methanol. they all like about 23-24 degrees of timing up top, and high 11s AFR.

Thats not the greatest idea in the world. atleast run 70% meth / 30% water.

StreetDreamz

Chad your estimates on the numbers are way off lol. Your car will peak at 11.8 given your lack of dual pass and bigger heat exchanger. Your timing will peak at 22 with the alky. We know your car was heat soaked on the dyno because you were out beating on it 20 minutes before the car was strapped on the dyno.

Darkmanx

thanks for the answer 2 months late , your a great toon er

StreetDreamz

Lol I had no idea this thread even existed!

2 days before the dyno his car was pulling a good 8 degrees of timing due to pure heat from IAT2s soaring over 180. He needs a dual pass endplate and he knows it. Otherwise the car is tuned for about 22 degrees advanced on a COLD COLD day that will keep his temps down to 140-150ish.
