Didn't happen fellas. The guy couldn't finish everything on time. Maybe maxus 10

 

I agree, for him to know that he put down 575 he must have a dyno graph wich would quite all of those yelling BS.
Id actually like to see that power curve if he is making 575 and his lists of mods, thats impressive.

 

Yes I dont think hal hit 500whp. I think when people heard he hit 476 then the rounding off started. Then people just said for a while oh we have 500hp maxima and that just kept running. Now I think Hal could have very easiley played with some tunning and got over 500 and yes Mardi may have had over 500 also but as now its all talk because we dont have it on any sheets. So 476 is the highest know to date. Iv never drove a maxima with over 350 so im not sure how it is and i had a set up with a hx35 I think I could have had around the 500 mark but after switch to the 6 speed tranny I have the same problems that TIlley had with his swap not being able to get the ring to read Right at higher horsepower and it distorting the signal. But on the Na's we have riding around with 6 speed swaps thier fine but when you try to push seirous power from them the dam ring want read right so I gave up and moved on to my 500whp 300zx soon to be 700whp.

 

I wonder if Meximax had those issues as well with his 6 speed setup

 

good question just thought about him.

Its a lot like spark blow out but its when the wheel is not completey in line with sensor. And when spunn very fast (turbo motor ) it becomes disorted and shut the injectors down!

 

Hals 476whp claim and 500+whp claim were two totally separate things. No "rounding off" occurred. I'm not saying he hit that because I don't know if he did without a dyno graph, but the claims were made at different times, with different setups, etc.

 

I have heard about these ring issues on 6-speed swaps, but not problems on mine. I have a "clean" read all the way to 7200 rpm while making over 450whp. I did check the ring runoff (offset) when I had my flywheel/clutch balanced. I don't recall the actual value, but it was minimal and has not been an issue for me.


96sleeper....your words resonate so personally with me. I will also agree that having anything north of 350 hp in a maxima is just plain silly. Its fun and all, but spinning tires at 95-100mph starts getting old really quickly.

About having the highest HP maxima....I do have my nitrous kit installed and know that I have a solid bottom end to support at least a 100 hp shot on top of my SC. But, I haven't done it in the two years since I built my engine, and it probably won't happen. It will be utterly pointless in anything below 4th gear, and worth nothing more than for bragging rights. As 96sleeper states, the limitations of the chassis start showing up (i.e. as you involuntarily shift lanes during 60 mph rolls)

I have added a different platform to my stable that makes as much power stock as my maxima does right now. Needless to say, it is well designed to handle it. I just haven't had the heart to sell or part out the maxima

 

FYI, directly form Hal's site. If memory serves me that was turbo + nitrous which would explain the high torque #

Stats:
11.9 @ 124.9mph with 1.88 60' low boost (11/7/04)
538whp 603tq (10/15/04)
High 400's on conservative pump gas tune

 

Lets see, Ypipe and CAI on Automatic. I'm guessing it's not me

 

oh boy.. here I am worrying about whats gonna break when I hit my high # goal of 370 for my daily driver.... .. for my build...

 

i couldnt have said that any better. When i had my 3.5 i had nothing but fun, 1st-5th gear. but as everyone else says, after 350hp, wheelspin kinda ruins it. i mean, i dynoed 374hp on 9psi and stock injectors, now im on 440cc's and 12psi spinning 3rd, and having a light frontend in 4th isnt too much fun. Actually gets annoying if it happens enough in one night.

 

i didnt have a high powered max, but it had 300whp, good for roll races, from a dig with open diff, forget it, i would spin like crazy, and then i started having all sorts of suspension and trans issues. no doubt the VQ motor good, and make power, but like sleeper said, after the 350 mark, the family sedan shows up, and the sport goes away. still to this day i wonder why maxima went to fwd platform, was it to follow a growing trend, or did they really think it was better?

 

You havent rolled on the street with some good drag radials that work well on the street , not just track.. i used a set with 393 whp, and that was sick!! dont expect any street tire to not spin... obviously,,, if you dont have rubber, you will spin in 3rd and then play the catch up game


I aggree though, hence why i never built a 3.5 back on the day when i had one, bc there is no point in making 500-600 whp if you cant put it down without breaking a tranny in these cars... 400 is a great number

 

What DR's did you use? Did it spin in 1st or 2nd? I probably have about 340-350whp with nitrous and traction is very frustrating. I'll spin 245/45/18's (20 psi) in 2nd and a bit of 3rd. I recently made some F+R limiting straps and I was able to get 90% traction in 2nd. It makes me wonder if I could get traction in 1st with DR's. I know I can get traction in 1st with my slicks at the track, but the street is a whole different scenario.

 

When I was running a 75 shot on the street on my 245/40/18 exclaims, I was able to floor it N/A in 1st, then hook in 2nd and up with the 75 shot, and that was with 111-112 traps... probably 340-350whp also.

You may hook in first on DRs, will just depend on surface and heat in the tires probably.

 

I was never able to "hook" 1st gear with DRs, but 1st was still much more managable (i.e. easier to pedal) than it would otherwise have been on regular street tires, and 2nd worked fine. A little squirrely but not pure spin like it was on non drag radials. I never ran anything more aggressive than the nitto DR on the maxima though. A stickier DR would have been even better.

 

Yeah I bet some hoosier or M/T DRs would be a little better than the nittos for straight line traction.

 

I ran nitto drag radials on my maxima full time. First gear never hooked track or street. 2nd gear would hook if the tires and road surface were warm. Cold tires (obviously) or anytime in the winter months 2nd gear would usually spin. I never had a problem with 3rd gear on drag radials.

There are other stickier drag radials but none of them last nearly as long. That was one of my biggest gripes with the car. Any rwd car on street tires would out-hook my car on drag radials.

 

if i would even get off my lazy but i could tell you how the mickeys hook. I have the 265/40/18's now but my car still isnt running. i am making it a point to drive it this year.

 

That's usually what I do, but I spin a bit NA in 1st, even with warm tires and road surface. If I set the nitrous to engage right after I shift into 2nd, It would just spin like crazy (without F+R limiting straps). i haven't tried it with the limiting straps. I have been able to get full traction in 2nd with my progressive controller, but It doesn't pull as hard and it's not as fun. lol.

That would be awesome if I could hook in first with dr's on the street, but I'm sure I won't be able to "launch" it hard with dr's.

I can't wait for my local drag strip to open. I'm going to try to launch it off the rev limiter and I'll set the 150-shot to engage at ~2mph. If it hooks with my small slicks and 5-speed gearing, it should yield an incredible 60ft time.

This is the same Hal that you bought your car from, right Neal?

Thats Hal

 

Yeah well dialed in suspension + proper street tires RWD cars can easily pull sub 2.0 '60 foots on the street and even hook in first on the high power autos.

FWD has definitely made me reconsider F/I plans on my maxima and go for a 280-290whp NA daily driver and build something RWD with big power.

 

That's exactly why I won't try to make any more hp in my maxima. I've been working on my vq s13 alot lately.

 

i used the BF Goodrich Drag radial TA's with about 25 psi on the street, and with proper feathering, it grabbed nicely , even 1st with some mild squirling.. at the track they werent any good though, def would go with slicks at the track. Those things used to pick up rocks and throw them on the car how sticky they were on the street.
