NEW PB, Supercharged Maxima.
Alrights, went to the 1/4 mile today and got way better results. I'm still kinda new at this and still have a lot to learn. My friend on the other hand is a lot more experienced then me. That being said my run wasn't clean (car problem). I have an issue with my tune which I'll post up in the forum with a video.
Issues aside. He ran a 12.938 @ 108.064 and I ran a best of 13.698 at @100.802. To be honest with so many little things worked out I'm happy I can consistently be in the 13's last year it was 14's with he same setup. A couple more little things to fix and a bump in the redline should make for a faster car.
Specs:
00VI power tube delete/blocked off,
V2 supercharger at 13-14psi,
Emanage and J&S (with my tune),
94 Octane pump gas,
Stock redline,
M&H slicks. Can't remember the size of the top of my head. Mounted on Jeep rims
Intercooled, 3" charge piping, headers, y-pipe, gutted cat, then to a 2.5" exhaust.
All right. Here is some proof,pics and videos. All of my friend not me. I gotta work out on my burnout
His ^^^
Mine ^^^
Slicks poke out so much, it's baller

BTW, just cause he got a better time only means he knows what to do at the 1/4 mile (it's not like I practice 1-4 power shifting on the street...) 12.9 was the only 12 second run he got. After that it was 13.3-14.3. All the stars lined up for him on the 12.9 run

In my previous car I had the same issue where the car only had a dek swap and I had the 2 step active. While cruising I could make the 2-step activate

Looks like your friend has a nice pass, and your car makes good power. I understand that it looks like he can launch the car better, but you should still have pretty much the same trap speed.
I am sure you will get a better time once you get the launch figured out a little better

He also has a good 5+ years at the strip.

345whp on a mustang dyno. I don't know man, maybe once the issues are resolved it will be faster. Until then I'll work them out and see what happens.

i know cars with his (our) power numbers should trap decently, but the power numbers (peak, especially on the 3.0s) are also very deceiving as we all know. so im just curious why you say that thats all...enlighten me.

you know, ive heard you make similar statements before concerning S/C'd setups. you once told me you expect 110+ traps from my car cuz of my mods. but when i go back and look through timeslips, i rarely see a s/c setup trap even 110. (based on my memory, research, and the timeslip database). is there something you know that we dont? i know cars with his (our) power numbers should trap decently, but the power numbers (peak, especially on the 3.0s) are also very deceiving as we all know. so im just curious why you say that thats all...enlighten me.

I agree with neal, the trap seems low. I remember running 13.8 at 105mph ( 2.1 60') this was on 300whp dynojet. That was on less then about 10psi through my auto. You with more mods than I had back then and more boost, should be having much better results, but like you say, your new, just practice. Im sure a 5sp is not as easy as an auto at the 1/4.

Where is your boost gauge source taped @ and what is that silver tube right after the maf coupler going to? I just curious to see if you have a vacuum/ boost leak and how u know your engine is seeing 13-14psi.
A fellow local org member and I thought we were seeing full boost only to find out we had major leaks everywhere... even the maf was leaking...lol

The fact that your buddy pulled a 1.7 but still only trapped 108 tells me it isn't the driver that's holding the traps back but some power issue. Unless you guys are just shifting super super super slowly.

250whp maximas are trapping 105-108 depending on the driver's ability and atmospheric conditions. His car is performing like a 250whp car, not a 350whp car.

trapping 108 with a supercharger should show that he has over 300 whp. I was trapped around 108 when I was supercharged and I had over 300whp (don't know the exact number since I never did a final dyno). Since my car has been 3.5 swapped, I trapped ~106 and I am making ~264whp. In my experience when comparing supercharged to n/a, horsepower for horsepower the n/a car will trap a higher speed.

I was assuming he probably made in the neighborhood of 330-350whp with his mods, and a torque number which is realistic for such a setup too probably in the 280-300ft-lb range when I said that.
Obviously there is a bit of variation with different tracks, drivers, and atmospheric conditions, but I feel 115ish is pretty realistic for a car with his powerband. If he'd trapped 112 then I wouldn't think anything of it really, because 3 or even 4 mph is within the realistic realm of variation. But he's not even close to that, he's still a full 4mph short of the low end and 7mph short of the high end in my estimation, which is why I think there's something wrong with his car. If he can get rid of the hiccup and whatever other issue he is having, I think his traps will go up big time and be more in that 112-115mph range. I think there's a big power disparity going on here between what he's actually making now, and what he made on the dyno (that's assuming his dyno number is valid - i.e. not a dyno that reads super high or anything like that).
Obviously SC cars with X hp number tend to trap a little slower than a turbo car with the same X hp number, because the turbo car will probably have way more torque, but I wasn't basing my estimation off comparison to turbo cars. I was basing it off what I assumed his power numbers (torque, HP, and basic power band shape) would be given his setup. 115 is the high end, but not unrealistically high I don't feel. I'd say 112-115mph is realistic for his dyno plot, if he can get the car making that power again and not hiccuping on the track, etc).
My basic point is that given any powerBAND, and keeping all other variables equal, there is a speed at which the car will trap. For his powerband 108mph isn't close to where he should be.
