Rest of car details in signature. These were recommended but they don't seem to match anything I see listed on the Spark Plug Charts. I know 7s are Cooler and these are definately non-projected tip. I ran them with no issues last year on the 200 shot but just want to get some thoughts from some of the more experienced guys. TKS.

 

Not at all, Im guessing you heard this from an import guy? they are wrong in all cases. haha. Plus it is a projected tip plug.

Run the B8EFS ngk#1049 which is a #8 plug and is the right plug for your combo.

 

It never fails......you always have to double check everything for yourself! Thanks for the heads up and the recommendation.

 

your 402 runs 10.9 on spray? what shot?

 

What camscam said. Curious to know what size shot you run too.

 

Better question is how does it run 11.8 on motor?

Something is wrong unless it weighs 5,000 lbs.

 

I think that is what shiz was implying and I know that is what I was implying just trying to ask in a little nicer way.

 

Car is a full weight 2001 Camaro Z28.....3900 pounds with Driver for the 10.96 run last year. I was running a 200 shot. I was also running at a mediocre track and on heavy 17" rims with ET Street Drag Radials. My 60 foot time on the 10.96 run was only 1.78 while the mph was 129. It was also definately laying down on the big end as well running rich as the N20 pressure dropped.

This year I have rear 15" Weld Drag Racing Rims (10 inch wide) on ET Street Drag Radials and Weld skinnies up front. I also added rear air bags, a dedicated fuel system from Nitrous Outlet and NANO. Once I get my adjustable suspension dialed in I hope to get into the low 10s. The one thing I have learned on this journey is it's not easy to go fast and it takes time and experience.

Bottom line is I know my car is not going to be amoung the fastest FBodies but I would be happy with low 10s in my neighbourhood. No runs so far in 2010 as track doesn't open until April 16th.

 

after looking at your sig the 228/235 cam in a 400" motor is like a stock cam and on nitrous even smaller. makes more sense now. I bet it idles pretty good.

 

I have to be fair and say that when the motor was built by W2W it was for N/A Street/Strip car. I never mentioned I was going to spray the car as I didn't know I would go that direction at the time. The current cam is quite lumpy and has surging issues from time to time. I personally have no experience in selecting a cam for my set-up....any suggestions for a better nitrous cam given I still drive it daily in the summer 5-6 km back and forth to work?

 

well that small of a cam should purr. the tune is probably a little off. 402 on nitrous that drives id go like

236-240 and 246-248 depending on the ratio of drive to go fast..... the lift is fine for afr's at 600-630. Since its driver and nitrous car 116 or so lsa but put 2 degrees of advance in it for the 90mm intake.

thats just me id bet someone will come in here and spout off a "magic box 87"or "super duper dong v3.5" or something to that effect.

 

What are the specs on the magic box 87? Sounds like a cool cam.

 

As above...thanks for the advice..that's why I love this site..you could never learn all this stuff on your own or it would certainly take a lot longer.

 

He says that because of my AFR Heads the NGK br7es hex size is wrong and they also come with a gasket seal not a taper like stock ls1's. The br7es and 8es wont fit. He still holds that I need either the bcpr8es or the bcpr7es which are in the same heat range as the br7es or br8es. Anyone else with 225AFR Heads like mine like to chime in...TKS.

 

hahahaha I have to agree mostly with shiz. I was going to say something around a 240/248 605/615 on a 116+2 or a 117+2. Would make for a fairly good driving cam and would like the bottle but not be a dawg on motor. Don't go and do one of those "Magic box" or "Super ding dong v.8963" cams. Everyone wants to stick them in their cars and be like everyone else. Strive to be different lol. Also please degree your cam or have it checked on a Dr. when you get it!!

 

Let me go check what we have in the AFRs in our 408 nitrous engine and I will update this post with that number....

It has BR7EFS plugs in it. They quit making BR8EFS plugs from my understanding. We have not been able to get ahold of any in a while. I have BR9EFS in my car with a 63 nitrous jet in it. I have 0 passes on it only some dyno time. Plan to do some testing in 2 weeks time on them though with a 63 jet before going to an 82.

 

Sounds like the converter might suck.

Brents car went 10.3's full weight N/A .... 402 with AFR's and 90mm intake.

Post up when you make a pass with the better tires. even at 3900lbs it should go in 1.5's 60' times.

 

I'm not positive about an afr head bt the plugs he reccomend are stil a projected tip plug and nono in a nitrous car. I would steer away from his advice if I were you.

And Pure they don't make the br8 but they make a b8efs plus that works great just non v power or what ever. Stock number 1049.

 

Ya all the EFS plugs are non v-power. I didnt think about looking for a b8efs.

 

Yup it is just non resisted compared to the 7 but that's no big deal.
