Time for some 1/4 mile testing.
Let's see if this ends well! So far I am 0 for Infiniti with this FD but let's just see if it can deliver this time around.
Looking to get some base line et and trap speeds for my new fd to see how it stacks up in a real world application. We all know dynoes can be made to lie and we know talk is cheap.
My last car with all the boltons was trapping 118mph on stock twins, motor, and tire size. The car made 365 rwhp so that sounds about right. I was confident that the car was running right and that the numbers were truth on the dyno print out. It made me sleep easier bc I am crazy. I think I even got a couple 119mph and one 120. But I'd say 118 was a solid and fair average.
With my new headache, err I mean fd I am looking to back up the 372 dyno that it put down with a decent trap mph. This car has all the boltons, bnr's at 15psi and a ported motor. The caveat this time around is that it has 18inch rims with 275 35 tires.
I want to do an apples to apples comparison. I know that tire size has an effect. How many mph should I handicap the new fd given the tire size?
Basically I am trying to manage my expectations. I don't want to go to track with a 118 or higher bullseye if the tire and rim combo is working against me.
Let it be known I will burn this thing if the numbers are lame.

Oh yeah. I know that if you get a ton of wheel spin the trap could be inflated. So let's assume a 2.0 sixty foot time which I think it a averagely decent launch. Obviously that not perfection but on street tires that's a fair assumption.

In regards to managing expectations..I can help with that 
hey man, this is a new car to you and your still ironing out the bugs. Think of it as a shake down. You cant expect everything to go perfect, but if it does then thats just a bonus!
Don't expect to beat your previous best. Expect to learn what you need to do to beat it and if you either learn what you need, or beat it, either way its progress and you win.
The rim & tyre combo is only changing your final drive ever so slightly, so probably wont make much difference assuming you shift correctly. After all, engine puts out same power no matter what wheel size you run. Your just changing the application of torque
Best of luck pal

The car isn't a top fuel dragster so don't try to launch it like one. Particularly on street tires.
Come out of the hole and roll into the throttle.
Trying to do otherwise will just get you a bunch of wheel hop, maybe some broke driveline parts and for what?
If it were me I would get a decent pair of MT drag radials and get after it. Street tires are pretty much a waste of time unless you are just doing it for giggles and not ready after the true potential of the car.
Me I could care less. I leave my pride at the gate and just go to have fun. I'm still usually faster than 85-90% of the cars there. But I wouldn't care either way.
Enjoying the ownership experience and time behind the wheel is what's important or you might as well stay home and watch greys anatomy with your wife or girlfriend.

I think perhaps we are missing the point. I am not trying to enter a competition or become a drag racer. I simply want to ensure that the car is running as it should for the mods I have done. So I was wonder if my tire size was going to impact results, however it doesnt sound like that is the case.

12.2 on crappy tires with poor sixty foot times 2.0-2.20. and by poor i mean not utilizing the car and power to its full potential. We all know that with Et streets or drag radials the 60' could be 1.60-1.80. But on street tires a 2.0 is fair and not a debauchery of a launch.

Where are you running it Matty? I've run some of my cars at ATCO.
With this cooler weather your car should scream. I just picked up a rotary FD and plan to bring it for the first time in a couple weeks for a test and tune. Nothing but a shake down to see how he car runs. Not looking for any numbers in particular. Just going to have fun. Will be taking it easy. Just looking for a MPH myself.

and look if i get a clean run i will turn around and go home. As i said i am not there to stroke my ego or impress anyone. I am simply there to learn the cars potential.
I wasnt in the room for the dyno pull. My BMw is probably a high 12second car and the FD is much faster. That is the only comparison I can make right now for certain.
The goal isnt for the fastest ET or to get back into the sport. Its purely scientific. If I get a 2.0 sixty and no mis shifts it will be one and done regardless of trap mph.

i have water injection. cool air helps but i got that covered. For anyone reading this I think water/meth injection is the best thing since sliced bread. GET IT
I am going to go to Lebanon. Cool air may also make traction a problem. Id meet you there but seems far for you?
I used to go to Etown back in the day quite a bit. It was more for grudge type stuff against my buddies.

regarding water injection, put it this way i was seeing 8degree intake temps on a warmed up car in 60degree weather the other day. it sprays under boost only obviously. I was in boost for 2nd and half of 3rd. if i made a full run i bet those temps would be negative. nothing like coming home and popping the hood and feeling the elbow next to the throttle body and its cold to the touch.

When I open the hood it's like opening a baking oven - can't believe water injection helps that much

It's a must. I was in the community just before this started getting popular. I think rich was running it at the time but only a few others. I didn't drink the koolaid at the time. I am not sure if it's popular now? Is everyone running it? It's an absolute no brainer.

Having said that, I find the car to be awesome if one wishes balance. It's tight yet comfortable. It's quick but not intrusive.my kids can go in it. Etx. It's a great car.
For me though it's not a car you ride. It makes going back and forth to the train station better but I am not going to drive the car simply to drive it. In the fd I will.
You know one thing that I find with most cars out there is that they don't pull to redline like a rotary does. I think that's a big input to the fun factor.

What kind? I have a 335i with cobb stage 2 aggressive maps and downpipe. That's it. The platform is amazing. You can grab so much power for $1k and keep the thing entirely civil. You don't need supporting mods really. I think the car puts down 330rwhp. The biggest beef I have is no lsd. That just rots. I don't feel safe squeezing the throttle unless the car is completely pointed straight.
