Is there a power loss while driving N/A with Tr6 plugs?

not that you will notice driving.

I lost 6 tenths with the Tr6's NA. Car was just breaking up the whole way down the track. Trouble is they foul up quick with just normal driving. They were ok for just cruising around.

Sounds about right to me.

6 tenth's seems kind of high to me. My car has gone 12.45 @ 114.88 NA fully stock internals on a 1.87 60', with TR6's. That would mean that my full weight + 12 bolt + a full 15# bottle of nitrous could have gone 11.8x NA full weight & stock internals on something like a TR55. Now my car isn't a stock internal car anymore, so I can't do a comparison. 6 Tenth's seems kind of high. I would think that 1 to 2 tenth's would be much more realistic. Maybe you had something else going on, or your plugs were really fouled.

My car has always run pretty good on the TR6's.

I couldn't tell the diffrence. I use them in a daily driver with no problems...

I've had mine in my daily driver for about 4 months with no problems either

Rougher idle, never checked NA time drop though.

This is the main reason why I am hesitant with nitrous. Isn't there a way to run strong both NA and juiced?

I don't want to be a "strong nitrous only" car.

It depends on what you really want the car to do. I have a direct port system on the motor, the motor was built for nitrous. The car went 11.05 on motor alone with 28" tall tires, 3:42 gears, nitrous cam-converter etc.-3500lbs + 116 fuel. I also have very little timing in the car because of the nitrous tuning. If I wanted to optimize for NA runs I could run a 26" tire or steeper gears and re tune for NA, maybe go to a lower octane fuel.
If I wanted to really get crazy with it I could change the cam, converter etc.
Not gonna happen.
In your case if you basically have a strong NA motor with maybe a 100-150 shot and all you have to do is change the plugs when you wanna spray- that's not such a bad deal. Look at it that way.

1ScrudeDude

Yeah, not so bad that way I guess. I would work on how fast I could change them out

I've went from TR55's to Tr6's, back to TR55's, back to TR6's. I'm going back to TR55's because at high rpm's mine raz's (fuel lightoff) when I decelerate ... smoke's like a bitch above 5500 rpms.

With TR55's, it doesn't shoot fire out the Borla tips on deceleration and it doesn't smoke at high rpm's.

I ran TR55s in my old car for 8 months. I hooked up the NOS dry kit and installed the TR6s. I could never tell a difference. Car still idled good, revved clean, and they never gave me problems during the 3 months they were in the car before I traded it off. I didn't use the spray much either, just one bottle that entire time. Most driving was cruising town and shorter trips.

About the .6 loss on someones car, I call BS. I had my car on the dyno with both plugs. The peak hp #'s were within 5. This is on different days and we all know it varies a small amount from day to day and the postion of the car on the rollers. I believe there was something else wrong with that car besides having TR6s. Different cars respond differently and I know that, but .6 is ridiculas. Not flaming anyone, just my .02, good luck to you all.

I have ran TR6's now for almost 3.5 years. I have tried both and never saw a difference between the 6's and 55's.

i've ran the same tr6 plugs for two years on a head,camed and nos car with no problems. my car lost no ET at the track when i switched from stock to tr55 then to tr6's for the nos.

I have ran my 4th set of TR 6's and never had a loss off the bottle with the plugs. Maybe you fouled one out. Maybe the car will burn it back off . Just a idea

I had TR6's in my 94 Lt1 heads and cam car and could tell no difference. I wouldn't worry about the .6 drop..there had to have been something else wrong in that situation, that is a very big drop.

Mike K.

I have not noticed a difference between stockers and tr6's either. I have not dyno'd with both plugs though so I cannot tell you 100%
