Nitrous plate system

I was hoping for more but
It made 489 hp and 535 tq on 100 shot
And 535 hp and 595 tq on 150 shot
Na with nitrous tune it made 389 hp and 385
Na tune makes 397 and 395 tq
Had to pull 4-7 degrees of timing for both shots
A/f was in the high 10's so it is safe
All I have is a airaid cai and cat delete pipes

You're WAY rich on your AFR. Being that rich is costing you power, and it isn't more "safe" then running a PROPER afr.

I agree with the above. Also you picked up right where the shot size was set, what numbers were you looking for? If you go off of the plugs and get that thing in the mid 11's will be just as safe and putting down a cleaner number.

Tried to go leaner and richer
Bogged when richer and made less power
Leaner made same power but got a little knock
I looked the plugs over good after each run

I might try a colder plug and lean it out more

No ECM tuning. To get all the power out of it, there still might need to be some jet changes.

What plugs?

No need for any nitrous car to have AFR in the 10's (as long as the plugs agree that what it is.

Also how are you going about getting a read on the spark plugs?

A plug flash light (old school)
Then was told a drill and hack saw blade trick also
Maybe the wide band is off but the car likes where it is
Carmel color and brown deep in the plug
And yes killed the key at very end off pull

You know why they call it old school? Because it still works!

The drill and hacksaw works great btw.

It sounds like the plugs are agreeing with the wideband. Definitely have more power with some timing pulled and leaning it out.

If you have knock you are way to aggressive.

Br7ef for sure.

The Tr6 should never be used with nitrous.

I Promise it is not helping. Plugs are more important with nitrous than on any other power adder. (IMO)

Honestly it just needs to be correct. You will hurt part's with a poor tune no matter which way it is. We make a point saying rich is not safe because people think "rich is safe" and run the cars too rich and make low power and still hurt things.

Im running tr6 plugs. Can you be more specific why they're not good for nitrous. What kind(brand name) are these br7ef?

Thanks, j-rod.

The TR6 is a projected plug vs the BR7EF which is non-projected. Also the BR7 is a step colder than the TR6. You can get the B6EFS for small shots that are the same heat range as the TR6.

I have been running the TR6's on the 100 shot only because I already had them but will soon be switching to the BR7EF for the 100-150 shot.
