guys running 24psi plus on pump what plugs are you using??

[GstRacer]

just wondering if all you guys are using bpr8's. and how long they last in your car??

 

[Burnett03]

7es here with 23psi and a 50shot gapped down at .028

 

[GstRacer]

would ignition affect the plugs you use?? i have msd and COP i used 7's on my setup and and they were running very hot

 

[CanadianTSi]

I ran BPR7ES's all last year. Switced to BR8ES's this year, there still fine after 3 months of Daily Driving.

Brand new BPR7ES here too. 23psi on 14b. Running rich and ignition pulled back on 93 octane and Im still pimpin the stock intercooler on a 2.3 stroker. I really need to upgrade some stuff.

 

[TurboAnything]

I ran 28psi on bpr8es on 93. almost no knock.

No, an upgraded ignition will only allow you to run a wider gap before misfiring. The heat range of the plug (or the temperatures they are exposed to) has nothing to do with the power of the ignition system.

 

[super95awd]

BPR8ES running up to 36psi on 93 pump (no meth injection).

 

[SolidBoostTSi]

I run BR8ES non projected tip plugs and No knock at all at 27 psi with mobil 93

 

[v8killer]

how are you guys running so much boost on pump 93 octane i have never got away with anything over 18-20 psi !

 

[1fastlaser]

Ive ran br8es for awhile on my setup before it broke. Never had any issues besides it blowing the spark out with a gap any bigger then .23 .24 on higher boost

Tuning...

 

[Boosted98gsx]

Not on pump, but BPR7ES gapped at .025 c16 with evo3 16g at 25 psi.

it depends on your turbo and tuning methods. If you have a large wheel capable at spinning up large amounts of air at low RPM, then your charge air temp is going to be less than say a 14b making the same amount of backpressure. The smaller turbos will have to fight harder, and produce more heat to maintain the same pressures in the charge piping.

Also, how the hell did you sign up here in 2002 and only have 14 posts? Can you say TROLL?

 

[v8killer]

havent figured out why it only says 14 posts but i/m pretty sure i had more than that i've have had my fair share of dsms and have been around since then, i have been away from dsms for about 2 years i've had 6 1g's and just bought my 1st 2g ! that makes since about the bigger turbos...... i normaly run smaller turbos 14b-16g ! going with a big 16g or 20g on my 95 tsi fwd ! take that for the troll comment p.s. i just realized it started the post counter over when i reset my password a few weeks ago, so i guess i have been away to long ! DSM'S RULE.........

 

[91-gsx]

BPR8ES running up to 36psi on 93 pump (no meth injection).

Now I realize running high boost has a lot to do with tuning, but how do you run 36psi on pump gas, and I'm guessing a normal looking timing curve without being really rich? I mean do you have a very low temp thermostat? Or do the plugs really help that much more? I have my plugs gapped at .028 and they are BPR7ES's, should I try a smaller gap? I have not tried to tune for high boost or tune at all yet, but I cannot see my self getting away with a stock looking timing map or better, along with high boost on 91 pump gas. Any tips would be highly appreciated, I'm sure we are all ears.

My guess is that he's referring to E85 as "pump gas"

Edit: nevermind maybe... didn't notice what car I was talking about. Now I remember the 10 page long thread with everyone arguing he couldn't have got into the 10s on a 3052 with pump gas

 

[1stGenRocks]

stock ignition, ngk wires, bpr7es gapped at .25 and 30 psi on a gt40. im running half e85 too but that shouldnt affect the plugs that much

 

[CPHunter]

Stock ignition,MSD wires,BPR7ES gapped at .28 at 26 on a GT30R. 91oct. with meth

whats e85 stupid question ###### but hey

 

[gsxtacy]

NGK-R BR7ES- up to 25 psi on 90 octane pump gas 8,000 miles and still kicking

Been thinking of trying the BR8ES's but didn't know if they would be too cold...

E85 is 85% Ethanol & 15% gasoline. Its produced from fermentation of plant sugars, they use plants such as corn. It's good for the environment & has a higher octane rating compared to reg fuel. I haven't read much about it, as it isn't available anywhere around here but have heard it is as good or better then race fuel. I know you need much larger injectors to run it & think you need a larger then the norm fuel pump upgrade as well.


As for some of the boost levels mentioned here (especially 36 psi on pump), I too am a little stumped how that much boost is possible on straight pump (no meth injection or E85 as I don't call that straight pump). Sure on stock cams, its fairly easy to see big boost levels but with aftermarket cams, I too can only run about 20 psi unless I want to pull a tonn of timing or dump a tonn of fuel. I know a better flowing hot side, only helps the situation but I believe the FP3052 Im running (or GT30R turbine wheel) to be a descent flowing hot side.

Race gas is still "better" than e85 but e85 is "better" than pump gas and costs less than race gas

I believe I had read E85 has an octane rating of like 105, which is obviously less then some of the different race fuels out there but I remember reading a post (think it was on here) were a vendor had posted that E85 will take you further then race gas, which didn't seem to make much sense at the time, but didn't look into it as like I mentioned its not available here.

 

[project_tsi]

I run BR8ES's on 30 psi on pump 93 + 50/50 water/meth.

Do those non projected tips help out a lot for timing?
