You can get Kosei K1 Racing wheels in 15x7 or 15x8 to fit even with the stock 5th Gen brake setup...

They are smaller in diameter and weigh 13.5~ish pounds. That would launch like a scalded monkey...

so removing a heavy pulley thats using power to be turned no matter if the A/C is on or not wouldn't free up quite a bit power? just curious...Im definately not one to go into all this motor talk because Im still learning but his times are legit no out of ordinary times were run from other cars. Like I said we will both be going back to the track soon to back this up and show its not just some fluke or clock mistake.

Actually they are 12.5 lbs and with slicks mine weigh in at the horrendous weight of 25 lbs exactly.

They also do launch like a scalded monkey.

Everyone should know that Craig is just joking so just don't pay any attention to his post.

Thank you, most of you, for your support.

For those of you that do not believe the 106 please be specific as to what it is that you're refuting so I can debate it. If you just think we're fabricating the story then please say so because I won't waste any more words on you.

I don't think you guys are making this up, for what purpose would that serve...and it would just be stupid to do something like that.

After thinking about the trap speeds, it just seems to good to be true. It does not make sense that you would be trapping 5mph faster than Blue does and the same as he did when he ran w/ the nitruous. What was it, a 75 or a 100 shot?? It takes alot of power to trap 5mph more. Much more power then removing a 150lbs of weight and the AC.

Do you think that the track you ran at calcualtes trap speed the "old" way. There was a post about it in the 1/4 mile forum. Some tracks use speed traps well past the 1/4 mile mark and drivers who stay on the throttle longer get higher traps. Up to 3mph. I don't know if this info is fact or not but that could explain the insane traps.

Just a thought.

Blu

iTrader: (63)

Rockingham is up to date with there timing system Im 100% positive of. The reason he is knocking on my trap speeds of my nitrous runs was my transmission troubles the day I ran. Now Im not making excuses but when it takes 2-3 secs for the tranny to shift it does effect trap speeds. These runs were also done at the same track as I ran at with the nitrous.

I plan to run soon with the AC removed as well as the tweaked manifold to see what I can get. Trust me before he removed his AC and did a little tweaking of the IM he really didnt pull on me hard at all. Now its just murder like me trying to race a LS1. His car is really as fast as the times say I have driven it and ran against it. The same day bolt on LS1's were trapping 106-108, srt-4's 99-100, buddy with a Auto LS1 with exhaust, and Lid 103.

What he did to the Manifold improved airflow on his SAFC 3-4%. I was running the same day and my best on slicks was 13.63@101.5 and I was gutted also. I know I will do better in cooler temps as usual but for 70 degrees I was quite happy with my times and amazed at SR's.

We will be making a trip to the track possibly again this friday and hopefully getting his car on the dyno to see what the thing is putting down.

I don't know why anyone would think you were not telling the truth. Geez if everytime I put up a new time last year everyone said that I would be the biggest liar on here.

I only disbelieve when there is good reason, plus I am hoping I can do something similar.

Any NHRA or sanctioned track has changed their method calculating years ago, it would have to be some obscure track in the boonies to do that. Heck even in Canada we have been doing it before the line for years.

Also don't ever discount the weight connection. My 97SE had a N/A 1/4 best of 15.4 and that is the same engine and trans I took out and put in the 95 GXE and the only other thing I really did was weight and I didn't really get too carried away with that, and it made a difference of .8 in the 1/4 down to 14.6. So anything is possible.

Galo

Matt....those are flat-out awesome numbers....outstanding work!

Dave B

NHRA tracks don't necessarily have to run the new trap speed calculation because it has no affect on ET. It's just a safety measure. I also know for a fact that a track in Ontario does use the "old method" and same goes for a few East coast tracks. My track didn't change thier method until 1997 when a few over-cammed (= weak braking) cars ran out of road and went into the trees.

Nice runs and great mph what is the elavation of the track and the temp the night you ran as far as my mods I have a full cattman y-pipe to muffler custom intake +3 deg timing and 5-30 sint oil. I did the runs on stock tires at 24lbs only lighting I did was the spare and jack + 55 lbs in rear tires

Elevation of the track is 400 above sea level. This was ran during mid day with the sun beating down temp was around 70-73 for most or the day.

Wow, so you're saying basically that SR20DEN got ~ the same traps as bolt on LS1's. I find that hard to believe given the mods simply because there's no dyno numbers and secrecy about the mods. I still really can't wrap my head around the idea of an NA 5.5 gen trapping near bolt on LS1's either. Good times nonetheless.

LEMAR

Tommy Boy

Awesome times!!! The weight removal shuouldn't be taken so lightly. The old rule of thumb is 100lb removed is worth a .1 in the 1/4. My guess is you took out about 175-200lbs, so theres .15-.2 right there..... My guess on the "special intake mod" is, a little grinding/porting just behind the throttle body or even into the throat for a couple inches and maybe a gasket match to the heads? Am I close SR20DEN??? I don't think you had it "Extrude Honed", that's more than a "little" work....The G35 guys are picking up 25-30 hp by having a company cut open their intakes and welding a 1 inch high piece of aluminum onto the front half of the intake because Infiniti made the front bank of cylinders starve for air. I havn't looked at the intake very closly, but maybe we share a similiar restriction???

In any event, GREAT JOB!!!

SR20DEN

Well the Ram Air LS1 that I Pwned on my 104mph run must have been thinking the same thing before the race.

I never expected everyone to believe these numbers and I seriuosly considered not even posting them. All I can say is that I will provide more proof by going to a completely different 1/4 mile track and reproducing the results. Also, anyone who rides in my car or drives it right now would easily believe it. The car feels like it pulls like a Honda on the top end. The ONLY thing I am keeping a secret is specifically what I did to the intake manifold. I have shared ALL of the other information even the exact weight of the car gutted with 3/4 tank and no driver (3041).

I also want to add that if you don't believe 106 then you best not check my next thread because I am certain I will better that number when I go back. However if for some reason it turns out that I can't do it again I will regress and admit that those numbers were a consistant fluke that happend 4 different times during the day.

Its all about power to weight ratios. It can be done, so long as you take all the ish off/out of your max.

muahaha

Dave B

Definately. To go 105-106mph in the 1/4 mile with a 3200lb car (assuming he's a fairly light guy) is going to take atleast 270fwhp with a very linear powerband and very powerful 4500-7000rpm punch. If he's only making 250-260fwhp then the track equipment isn't right. The power to weight ratio to propel a 310rwhp 3600lb (driver included) stock LS1 F-Body into the 105-106mph range is about 11.6:1 give or take a tenth. The 5gen Maxima has nearly the same frontal area, CD, and gearing so it would be only right to assume it will take the power to weight of 11.6:1. The powerband of the LS1 is from 4200-6200rpms whereas I'm assuming SR20DEN's is roughly 4800-6800rpms (assuming he's running the Techno ECU).

Let's put some other cars into the perspective. The E46 M3 makes about 270rwhp and weighs about 3200lbs and goes 104-105mph in the 1/4 mile, the C32 AMG makes about 310rwhp weighs about 3600lbs and goes 105-106mph in the 1/4 mile, the STi makes about 270whp and weighs 3300lbs and goes 104mph in the 1/4 mile.


Dave

The camaro has a .34 cD, and I dont think that they quite make 310 rwhp. He would have to be makin about 380 crank HP with a manual tranny. I know they are 310hp stock, but I dont think bolt ons make 70hp @ the crank. The main powerband (of a stock max at least) is 4000-6200 rpm. with the TS ECU, it allows the powerband to go to about 7k, Also (for autos) it lands you in the sweet spot in the powerband on the 1-2 and 2-3 shift

SR20DEN

iTrader: (7)

I weigh 240 pounds so my race weight that day had to be about 3270ish with 3/8 gas when I got to the track. I do not have the TS ECU and my rev limiter only goes to the stock 6600. Blu who isn't as familiar with driving my car got 102mph and he only weighs 140 pounds. Had he more practice on my car, which is not easy to launch or 2-3 shift, he could have bested my 106 that day.

Chinkzilla

Dave B you're comparing apples to oranges. An E46 M3 is not a Maxima is not an LS1 is not a C32 AMG. There are too many variables to take into account not the least of which are the removal of accessories, rotational mass cannot be discounted. BTW the curb weight of an E46 M3 is 3461 Lbs. I think it's fairly possible he accomplished this with 255-260 whp. Which is still an incredible number, highest that I've seen on an NA maxima. I'm really curious to see what the IM modifications produced. I would pay for a new fabricated aftermarket IM, but I dunno about something i could do with a few dremel bits at home. Can't wait for the dyno's

Blu

iTrader: (63)

So basically your saying if he doesn't make 270whp the track equipment is wrong but is dead on for everyone else? I believe my race weight was approx 3230 with me in the car and 1/4 tank of gas. I make right at 230whp and was trapping 100-101. Sounds dead on for me as well as all the others tracking there car that day. I know its not NHRA but the IRHA spring nationals are ran at this track the the equipment is accurate and up to date.

Dave B

I've watched more LS1s F-Bodys dyno than I can remember. Pretty much if it isn't making 305-310rwhp stock, something isn't right. I've watched quite a few stock 00+ LS1s put down 320rwhp stock. To say the LS1 is underrated is a gross understatment My buddies 99 Z28 automagic made 320rwhp with longtube headers and an intake lid.


Dave

Blu

iTrader: (63)

well I have seen 3 00+ LS1's on the same dyno I use put down 285-290whp bone stock and an Auto with a lid and exhaust make 298whp. But all dynos are different so I guess mine reads low b/c I seriously doubt anything is wrong with there cars.

Dave B

I don't mean to harp on this, but there's no real way around it. He's got to be ~270fwhp to pull that kind of trap (assuming the track calculates trap speed with the current method). As for the LS1s that were running, how do we know they were good drivers? Since they're not posting we don't know if they were getting 2.3-2.4 60 foots and/or missing gears. I've watched all too many LS1s light the tires through the gears 1-3 and bark 4th and still end up with lower 14s at 102mph+. I've watched these same guys throw on slicks the same day and turn around and bust high 12s@110mph+. I'm usually hanging out with my F-Body friends when I'm at the track so I'd like to believe I know what these cars are capable of.


Dave

Dave B

True it's apples to oranges car wise, but don't you agree it's power to weight that ultimately matters? All the cars I listed have very similiar powerbands (4000-7000rpms) and have the same kind of power delivery and weights. Many of their torque values are different, but most of that is brought into check by either their longish powerband (ex M3, peak power at 7300+ rpms) or weight.


Dave

Blu

iTrader: (63)

Well considering I have said they do calculate times with the new method twice I guess that means nothing. Here go to www.rockinghamdragway.com give them a call and ask for yourself so you can quit harping on that. Im not trying to be rude but you seem to keep bringing that up when it has already been answered. As for the good drivers bad drivers that excuse always comes up and can never be proven. My friend Alex has an Auto 00 LS1 t/a with exhaust and a lid. He is the one that made 298whp on the same dyno I use. He was running 13.2's @ 103-104 that same day. Like I said calculate mine with your method 3230 with me in the car 230whp and trapping 100-101 the exact same day.

SR20DEN

iTrader: (7)

To this point I agree with you. I even commented privately to a few people that I fail to see how this car could go to the dyno and not topple the 240fwhp mark. It simply would not add up otherwise, even with the very broad curves that this engine makes. But with all my experience of the 'humblemaker' I have learned not to speculate hp numbers at all because my thoughts and hopes always get shot down on the roller. So at this point Im not sure I care what it produces. Somehow it did what it did that day at the track and I can't be happier with those results.

I guess you're the guy Matt is going to get the video from to post it. Is there any progress on this yet?

Man, I can't wait to download this and show it to the fellaz here, none of them believe me, there's a local here who bought a WRX and has done his own mods and says that his car is faster than a stock STI.

He is having trouble believing that a Max is faster than his car, so I'm waiting for the video to shut him up, I already showed him all the other vids I have and he got so scared that he was going around looking for a used laptop to add in a standalone FMU to get his numbers up.

I wonder what he is going to do after he sees this vid.

Come on fellaz, post it already, you got us starving to see it!!

This is from a mustang board
A Mustang cannot beat an LS1. Simply cannot happen. Please refer to this guide if you're a Mustang owner that thinks you may have beaten an LS1.
#1 The LS1 cannot be beaten.
#2 All Mustangs are stock.
#3 All LS1s run mid/high 12s bone stock from the factory.
#4 Even the 03 Cobra is a mid 13 car.
#5 The LS1 was not racing.
#6 The LS1 was parked.
#7 The LS1 was just playing with you.
#8 The LS1 was actually a V-6 with Z28 badges.
#9 The LS1 was actually an LT1, which can only be beaten by an LS1.
#10 The race does not count because it ended before 160mph.
#11 The race does not count because it did not start from a roll.
#12 The race does not count because the LS1's passenger was performing oral on the driver.
#13 The race does not count because the LS1 was not properly tuned.
#14 If you still feel your Mustang may have beaten an LS1, please see #1.

I'm sorry but I forgot some of what you posted but did you remove the power steering belt. I noticed that my car felt a little quicker with it off. Also since you are trapping at 106mph, doesn't that make your car 12s capable. Whats that best 60ft you have gotten and on what kind of tires. Those are damm good times. Keep up the good work.
