I would think you would at least pick up 100rwhp if the tune was right.

I picked up 1 full second and 10 MPH in the 1/4. From 11.50 to 10.50. According to the drag race calculator, that is 140HP for whatever that is worth.

off topic, but would going from tr6's to br7 make the car run richer?

It might affect drivability but you should be fine at WOT. That's the plug you should run anyway. Gapped at .028-.032.

Plugs have no control over the fuel mixture sent into the cylinder. They can affect how completely the mixture burns. Hotter plugs keep themselves cleaner and resist fouling.

The general rule is your spark plug must run hot enough to keep itself clean at idle and cruise but cool enough to not cause pre-ignition during WOT and racing.

You may find that the BR7s do not keep themselves clean in normal daily driving. You may actually fowl a BR7 around town depending on your combination. I personally run TR5s or TR6s for daily driving then swap in BR7s for running nitrous.

Reason I ask, with no other change made other then swapping from tr6's to br7's, car is running 11.4's n/a, whereas with tr6's it was 12.5's

Neal@NitrousOutlet

you should pick up between 100-125 hp. Time would depend on if you got traction. TR& would be a great plug choice. They usually;y don't effect drive-ability and they will not effect AFR.

Gotcha, I actually switched to a br7 plug from a tr6. and car somehow went from 12.4s to 11.5 AFR's on a wot pull. I used the Diablo intune and removed 4% global lean and now she's at 12.0-12.1. Wondering if i should keep removing fuel percentage to get her in mid 12's afr's??

If Carter it's right, I think i found my answer here:

I tuned mine on br7ef and run an b8ef now and it doesn't foul plugs street driving. If you tuned it on tr55 then stepped to a #7 then I would say you might have drivability issues but stepping down one heat range shouldn't affect it that much if any. As stated, it doesn't affect fueling per say but too cold of a plug keeps the fuel from burning off correctly.

thanks ^^^.
I'm thinking something's up with the afr gauge (AEM UEGO) when i spray the dry 100 shot the gauge just goes to 10.0... Trying to find out why

not to hijack the thread, but what would be the best plug to use on a high milage untuned 75 dry shot that gets driven daily around town??

Are you adding addition fuel in the tune for the dry shot?

TeEnAgE pHeNoM

You need an ngk br6ef.

i tried that but since its a pre maf it was overly rich so i had to take the fuel back out

If you think your wideband o2 isn't reading correctly, try cleaning the sensor and doing a free air calibration. Also double check your grounds.

I would also suggest cleaning your maf since you stated it went rich at WOT after the plug swap. It could be strictly coincidence but it could explain the rich condition on motor and on the kit.

i'm thinking Maf related, i'm thinking about cleaning it and/or moving nossle just post maf..I could use the intune to add all the added fuel for a 55n jet? if so, what global percentage should I start with?
