Those are some big pump gas psi numbers. Are you guys that are running 25psi on pump running water injection?

 

[krisj144]

If I was running water injection, I definately would have said so. Yes, I agree, I'm reaching the limits of what the 660's will do for me.

i had a S20g tdo6h and ran 24psi on 93 octane... knock was around 8 .. when we had over 100* days 4th gear pulls would make count at 10.

 

[95AWD_TSI_TALON]

On my car Built 6 bolt- 8.3-1 JE's. I am running 23psi on 93 octane with 0 knock and sometimes VERY low ( 0.4) in 4th. In low 20ish degrees. And with the translator I was flowing as high as 55lbs/air reving out to 8k. Mods-850's,walboro rewired, crower stage 3 cams - springs-retainers , 2g ported head,1g intake-TB. also full -6an fuel line from tank

 

[JiveMasterT]

for those of you with crappy octane, trying using toluene as an octane booster... make your own race gas...

[RACER-X]

Ok now i'm confused.. is it pronounced 2leen?? and is this form of fuel clear? I could have sworn that toulene is what we use to clean our oil, and greased up bearing at work... aka varsal.

 

[kpt4321]

Most fuels are also solvents.

 

[Nos~4G63]

I beleive it is pronounced tow-lean. Awesome tuning guys! The cars in here that are taking the 3065 over 25psi on pump, are you using a stand alone?

 

[JiveMasterT]

toluene is a chemical used in paint thinners and stuff like that, but since it is 114 octane, it works well as an octane booster as that article explains.

 

[95AWD_TSI_TALON]

I am running dsmlink and having no problems. agp t3t4 60-1 kit at 23psi. and stright 93- no octane additives.

DSMLink and a MAFT. Doesn't really require any "special" tuning. My setup just takes alot of boost without complaint.

 

[G_S_X]

uhhh is there something i am missing them? how come i can only run 19psi on 91, and u can run 25-26... please.. help me, everyone is telling me their setup but WHY cant mine do that?

 

[mike97gsx]

What are you tuning with?

I ran 20-21psi on my 50 trim using 91 pump gas with maybe 1-2 counts of knock in the upper RPMs - this was with the DSMLink. That was in AZ. Of course, I could never get away with that in the summertime there, then I would lower it to about 18psi and it would run great. I'd imagine you're running into the same problem in CA with the heat. 91 octance plus 90-100 degree temperature isn't boost friendly. Try again in the winter.

[95AWD_TSI_TALON]

On my old 16g/smic I was ran 91 once @ 20psi and I knocked crazy as heck. Then put 93 back in and she ran fine. 93 compared to 91 makes a huge difference under higher boost.

Inlet temperature and I/C efficiency has a large effect on pre-ignition when running high boost levels on fast burn fuels. I don't think anyone is suggesting that they run without any knock. However generally on pump gas you will make more power with small amounts of knock, then you will with a zero knock tune.

I found when I moved my inlet location to ambient. The knock sum was reduced with no other fuel or boost corrections from my previous under hood 190* ingestion location. My setup includes a indy race core fp3065 and 750cc injectors.

oh great i think i just started another CAI debate

I only agree if by a small amount of knock, you mean less than a degree of retard.

Any more than that, and you're losing power due to the timing being yanked.

Definately. I can't wait to get my FMIC installed and a nice duct rigged up to my filter from the stock SMIC location.

It's all set, only a moron will say they are useless.

You're probably right on this one I don't have enough dyno time to offer any real hard data to support or deny this. I think timing does not get pulled until over 10 counts of knock correct? I try to keep knock under 10 counts but I have recorded as much as a 16 counts on a very lean pump gas run. ET and trap speed didn't seem to be effected, actually i *think* that run was a little quicker.

1g ecu "knock counts" and DSMLink "degrees of retard" are different animals. I think on a 1g timing starts being retarded at 7+ degrees. Not sure how exactly they would compare.

They aren't in California. They can buy real gasoline instead of the special horsepiss the State allows here.

If you're younger than about 30, you don't even know what gasoline smells like. I don't know what that crap is that we're burning, but I've glued models together with stuff that'll burn better.

is it me, or has defiant been pissed about something for the last week or so. .

Guys, I almost never tune on pump gas, but one time I did a bunch of pulls on some Sunoco Ultra (they were using 94 back then). I was able to make 340whp at 23-24psi of boost on a TD05 20G using 550 injectors (imagine that…). That is when I started seeing knock (it was ZERO prior to that boost).

Switching to race gas allowed me to raise the boost to around 25-26psi, before I started seeing knock. And I made around ~465hp with that boost. I was surprised that the difference was that small.

I happen to think that you CAN make some decent power on pump gas, the problem is that you never know how good that particular batch of gasoline is… So I am not impressed by “pump gas” numbers…

My fuel control was the same as it is now (VPC/SAFC/TMO).

Defiant is always pissed off about SOMETHING.

I was running as high as 26psi on my 56 trim, until I got it tuned and saw that my knock count was at a astronomical level. So I turned it down to 18,5-7 counts, and still managing over 300 whp/tq.

BTW, mostly I run with 93 Octane, unless I go to Sonoco, and they have 94.

 

[GRNDSM]

>unless I go to Sonoco, and they have 94.

Not anymore . Ultra 94 was phased out, replaced with Ulstra 93.

Some areas might still have 94, but not for long.

That sucks. Well for now we still have it down here.

GSntncT - I have a similar setup as you ... at what rpm are you seeing full boost and how much boost are you running? I wasnt even getting 20 psi till around 5k .... :thumbdown

High boost used to be @ 26psi, and it wouldn't hit that point till just after 5k, which I thought was weird considering the research I did on it before I bought it. @ 18 psi, I hit boost in the mid-hi 4k rpm range, which I think is kinda odd too, but maybe it's just me.
