FLY BY, maybe I missed it, but have you ever posted your performance gains (be it dyno or 1/4mile)? I'm curious. Your setup looks nice, and seems optimal

 

What I think.

 

I dynoed an uncorrected 270 (267 corrected) to the wheels as is, want cams and hope to be well over 280. I ran the 1/4 last weekend in 100% humidity - terrible HP conditions and went 13.6 at 105 MPH. I think I could have run a 13.3 or so on street tires with dry air and more effort for a better launch. Normally I will run a 2.0X sixty foot but apparantley chose to go easy with some 2.15's. Next time I go I will wait for good air and I will concentrate more. We were really there to watch the twin turbos (Skidazzle and t32gzz).

 

What is your estimation of avg 1/4 mile times for the stock Z? I've seen numbers that are all over the place. When I saw that Road and Track got a 14.4 with the Z, I was surprised. Would you assume, given good weather conditions and the perfect driver, that every stock Z would be able to acheive ~13.7 (Or are those just above avg Z's)?

Assuming you gained roughly 30hp with your performance mods, would acheiving a 13.3 next time be expected for your particular increase in hp, or would that be a conservative estimate?

Btw, what did skidazzle and t32gzz run?

 

Yes, and mine will be WELL over 280 with the pulley and flywheel as well !!! WE should be good for some Saturday night bets ...

 

Why did you by a Nissan product (Z) then?

I read the test from sport Z and the Borla was clearly not a good solution from a purely performance gain standpoint. Look at the area between the curves, and look at the torque gain - Nismo was better in both cases.

Do you work for Borla - because what you are going on about is nonsense!

I think that an avg 1/4 mile time has to be looked at given the exact same track was used to clock the time. In San Antonio there are two tracks and one of them consistently shows about 3 MPH faster than the other. The one that reads fast is wrong.

At our local track in Dallas, the best I ran stock was 14.19 @ 99. I do not give too much credence to the guys who think they are faster than me or others because their track gave them faster numbers. Just like a dyno, it can only be used for comparison when looked at apples to apples meaning same track comparisons. So picked up .6 in the 1/4 with the mods I have and I can pick up another .3 with a 2.0 60' (which I had for the stock run) and another .2-.3 with good air (which I also had for the stock run). Overall, I think that I can see a 1.00 faster time at my track compared to stock given similar weather and driving (which I sucked Friday).

I do not know how much power I gained from stock as I did not baseline my car.

They both ran 13.0's with one smoking his clutch and one being at the track for the first time ever. Not bad for the humidity and given the circumstances. Both cars have a lot better times in them.

 

So are you saying the guys that think they are faster than you most likely got their faster times because of inaccurate track equipment, or that they were closer to sea level, with better weather conditions?

 

FLY BY Z

those are some awesome numbers, the Nismo and UR pulleys are my next mods, based on your numbers, I should see some good gains there with the current mods I have.

 

Well, I haven't really talked to anyone about times or who is faster so there's no competition or anything. I am just saying that they won't run the same times at every track. But that's just common sense. Why do you run different times at different tracks? Because of the things you mentioned. There are many factors including weather and different measuring equipment, etc. I can't say why JoeSchmo ran a 13.5 stock. He is either lying or it's just the track he is at. He won't run that here. Our track is an NHRA certified track that hosts National events and Division 4 points meets. I have confidence in that at least. For instance, there is another modified NA Z that is running 14.2-14.3 here. He doesn't have all the crap I have, but still. It isn't stock. So there you go.

 

RodH, be sure to post your results!

 

But wouldn't you agree that the lowest time you run shows the full capability of your car?

You gotta remember, you're looking at drag times from a realistic (in terms of consistency) racing point of view. Alot of other guys are looking at it like a "here's what me and my can can do on a good day" point of view

 

I am not trying to discredit the value of 1/4 mile results, just the notion that they are comparable across the country.

 

yeah I got you. I agree.

 

Indeed, there are some slow strips out there. One closest to me about 60 miles north (Palmdale LACR) is a NHRA drag strip, but at 3000+ elevation. Anywhere from .5 to .8 seconds slower than other strips. They even have a correction calculation chart on their website. The only thing that place is good for is to see how well you do compared to a challenger or to go back often to see if you can beat your old score. Stock Z's there can expect to run mid-14's.

Just more evidence to back up whats being agree'd on.

 

The Nismo Cams are made by JWT and the Nismo Headers are made by B&B! I find it hard to believe that Nismo (JWT) 262 cams, are going to only make 10 rwhp combined with everything else, I sure as hell gained a lot more than 10 rwhp.

 

Looks like you made 21rwhp and 9rwtq with intake/exhaust/cams over your stock baseline of 233, right?

Given multiple instances and reports where that specific intake/exhaust combination alone has net approx 10-15rwhp, how do you figure you gained a lot more with the cams?

 

ACTUALLY ...

252 - MODED
233 - BASE
--------------
19rwhp Net Gain ...


Add headers, cats and plenum ... you will see alot more !!!

See my mod list ... I hit 280rwhp and 260 rwtq

The Nismo cams are rated at 15rwhp on a dynapak dyno. You will lose at least 2-3 using a dynojet due to the increase of rotational weight on a dynojet. That being said, you should see around a 12-13rwhp increase. zxsaint is pretty close on.

AND, the Nismo cams are NOT made by JWT. JWT did the original grind and testing for Nismo. Nismo outsources them now. JWT makes their own cams and they get another 2-3rwhp from them.

 

What is typical shop labor to install cams? I've heard 10-15 hours. Is that right?
