For those of you with FI - Who's in the 10's
 

For those of you with FI's - Who's in the mid 10's and how much did you spend to get it there. If you don't mind sharing your #'s I'd appreciate it.

I'm thinking about doing this ... However, I'm also thinking it might be better to get a 02 ZO6 and build it instead. If you guys are putting over $20K into making your Z's break into the 10's I'm thinking about buying another used Vette and dedicating it for the drags and throwing a Procharger on there.
I saw a Z with 550rwhp but, the guy had over $30K invested in the mods.

Before I bought the Z I considered selling all cars and buying a GTR. That was until I sat in one and calculated how much I'd have to give up to get one. Plus, I was thinking they had a rear seat. There isn't a usable rear seat in a GTR. You can't even put your kid in there. There is NO room for even their legs. like 1" (not kidding) of leg room. That really turned me off on the GTR.

I'll bet if you had SC that produced 550rwhp on a Z you'd best even a lightly modded GTR. Throw a set of TT's or big SC on Vette and you'd have the same fun.

Please share your experience here ....

I don't see lot of FI guys share numbers, few have their numbers here

haven't heard on anyone hitting 10s

No one on the street is in the tens. Certainly that I am aware of. The only car that MAY have been in this league has been modded to the max, and is now running nines out of Vinnie Ten Racing in NY. (Do a Youtube search)

There isn't enough traction available with 2wd to even keep up with a stock GTR. I know. I have as much or more power, and my car is still half a second behind at best.

I'd love to see this, but haven't yet. This doesn't negate building one. From a roll, the car can hang. And, for me anyway, I have a full back seat. (nya-nya! ;))

2wd and the tranny is why you cant compete with a gtr from a dig

Plenty of ten second and faster cars out there that are 2WD (e.g. Supras/Cobras/Vettes). All about getting it to pavement, which will probably take some awesome drag radials and a great driver. Back in my M3 days there was an ex-pro (or semi-pro) drag guy that drove his E46 M3 to ridiculous times. I watched some videos of his footwork and it was truly amazing. So far advanced from my own drag skills.

Exactly. No reason you can't break into the 8s with rwd. Faster than that probably ain't happening though.

Your going to have to put a full cage in the car. to go that fast.
and tons of RWHP!

Z

There are plenty of 370z's here capable of a 10 second pass. 550rwhp is enough to do it.

You will find, that even in the next 5 years, not many guys will actually run a 10. Its because of the type of person that chooses the Z versus other performance cars. While we all want our cars to have that power to be capable of the time slips... Z owners are not typically into drag racing their car at the track. Its been the same way with the 350z/G35 crowd. There are tons of cars making 550-700+ rwhp, but very very few of them bother to take the car to the track... and of those that do, almost none of them set the car up for a clean 1/4 pass.

The real difference is in the wheel, tire, and suspension setup. To get the best times out of a RWD car for 1/4 requires a vastly different configuration of those components versus what handles and performs the best on the street. The Z, when setup to handle and brake like a super-car (which is DOES do), cannot at the same time lay down all the HP. That is the difference between a car originally engineered to be a super car. They use tings like rear mounted transaxles, or mid-engine to be able to better handle the dynamics of all angles of performance with a single configuration. These days, supercars also use very high-tech transmissions... and a transmission setup makes a HUGE difference in 1/4 times... guys that swap to autos in their high power domestics can often drop as much as a second in their 1/4. Didnt someone here drop like .3 or .4 seconds just from a auto trans upgrade in their all motor 370z?

I think that a full street performance built 370z could perform like a 2013 GTR in all dynamics aspects, assuming the GTR is stock. But once you go into a further league, like a highly modified GTR... the GTR is going to be able to take the envelope further from all angles while remaining in a single configuration. The Z will start to require specific setups for the task at hand, such as a different combo of wheels/tires/suspension setup to drag race versus what we would run for optimum all-around performance and appearance.

Next year, you will definitely start seeing some 10 second 370z's. There will be more 370z's with those timeslips than 350z's simply because the engine is more capable/reliable of the required power without a full build.

I predict that there will be more auto's doing it, because an auto is much easier to consistently drag race, and it has more aggresive gearing and faster shifts. But the 6MT guys will do it also.

Last week, a full weight (3695lb) twin turbo Viper, still maintaining the independant rear suspension, using street legal 15" drag radials, ran a 7.119@201.34mph. Its a new setup too, he said he is still ramping in the boost slowly. I will bet anything he hits 6's very soon.

RWD is not holding anyone back from drag racing... it just requires the right setup.

Was referencing 370 build. Other cars are another story. The s197 should be going 7s shortly.

Charles (phunk), I'd like to see this happen (370z's in the tens), but I have big doubts. Your assessment of the type of owner is spot-on and that will limit some.

There is NO WAY my 537 whp is going to get my car close to the tens in my ride. I'm going tomorrow for a final time, but my goal is to nip the 11.6's.

It would take a VERY built and high stall speed torque converter, or an aggressive 6spd launch to get into the 1.6-1.5 60' times this would require. (I'm hovering around 1.85").

Don't see this happening in one year, but I'm ever hopeful. :)

Yes, 2wd can do it. See below. Also all out drag slicks, and not street drags.

As an irrelevant teaser, here's the World's Quickest Supra with Independent Rear Suspension:

I'm going tomorrow to Atco. Who's in? ;)

I'm guessing that my -2.4* of camber is not ideal for putting the power down for drag racing :icon17:

My sole interest for drag racing this whole past year was to beat my stock time. I think once I do that, I will be done with it for a while. I definitely think autocrossing is a lot more fun.

A friend of mine with a full weight 350z 6MT was able to run a 10.9 at about 525rwhp, he was using a set of slicks and was able to achieve, I think, a 1.58 60'. He is experienced and shifts great, and I doubt that there was much left on the table. I am not sure how much heavier a G is over the Z... but I think that a 1.6 60' could be had on a large drag radial, at least with a 6MT... im not sure what the options are for launching the auto trans. But I think that 550rwhp and a 1.6 60' with flawless shifts, should place a 370 into a 10.9. I believe that could be done with a great run on a 335/35/18 drag radial with an 18x12 wheel. That is what I am going to try out myself in spring... I may or may not have already swapped in a built motor by then.

You are right about the auto trans setup... I didnt really mention that it will take quite a build in the trans to launch the auto that hard... I think that a built 7AT will do the job better than the 6MT... but I guess that I wasnt considering how few of people will actually take a 7AT trans build that far.. so perhaps the auto trans in the 10s will be fewer than I was thinking in my last post

Charles,

Good info about the 350Z. Any vid? :)

If anyone is going to get close, YOU are. I can see you have the knowledge, and, will have the package for drag racing to acheive this.

Wish me luck. :)

Coop

Good luck!

We will see! I really WANT to drag race my 370z. I have all the intention in the world to do it, hopefully time and budget allow it. But wheels and tires for it are currently in the works.

I had a twin turbo 350z from early 2004 until just a couple months ago... and the last time I took it to the track was in 2004! At that point, the car had made 573rwhp at 14psi. But I was trying out a sleeved block and the sleeves settled and the headgaskets started leaking right after I got off the dyno. To run 14psi was spraying coolant all over my windshield. I went to the track anyway and ran it at 11psi, which was about 520-525rwhp IIRC. I had a 295/35/18 (i think) BFG drag radial on the car. I cant remember all the specs of the run, but I had a wheel hoppy launch, did OK after that until 4th gear the car lost a lot of power as I think the headgasket really just gave up as coolant sprayed over my windshield, it really distracted me and I missed 5th gear (which probably didnt matter because it was like right at the line) and coasted to an 11.6. Went back to a non-sleeved block and never had another problem with the car again but never got around to the drag strip again.

Here is Bri's 350z 10.9 run:

350Z Twin Turbo 10.96@127mph - YouTube

In-car 10.96 pass - YouTube

I guess we just wait for Z Elim's GTM Stg 2 SC Install and his built 7AT ;)

I agree with Phunk. Not many 370Z owners have the budget for FI, and only a few of those owners will be hardcore drag racers. "It's not a drag car" as most people like to say. You know it's bad when every night at the track, the GTR's outnumber the 350Z's and 370Z's combined. I've seen lots of random Z's at the track. Most never come back after their first night.

If anything I think it will be a shop car that will pull it off. Either that or a really dedicated, hardcore 370Z owner to make 10's happen.

I think with a small rear brake kit and 15 in slicks, race gas,13psi and a a few lightening modds and I would be 10's easy had I of kept the car that would have been my winter project.

Charles, thanks for those two vids. Inspiring.

I did not fare so well yesterday, and that's how it goes. Read here.

Coop

with some seat time and a set of slicks, I know i can drive a tt370 into the 10's. My very first pass on a street tires netted me 11.7's

Well if you guys don't pull it off I will when I go to the track. I just dynod 583whp and 468trq on 12psi = )
I trapped 127mph in 100 degree weather on a crappy track. That trap is good for a low 11 sec pass. And that was when I was making 527whp.

And yes I'm pushing the hell out of the stock block but oh well. Its getting built in a couple months.

Just make sure you have someone there to get a video, I wanna see it.

Will def do buddy.

Wow 12psi is that on pump gas or race gas? Any more updated videos of your Z?:tup:

what was the time exactly, and what was the 60ft?

That was on pump gas 93. Nah I haven't done any vids lately but ill make one for you guys soon.

It was 11.7 @ 127. And the 60ft was I think 2.1 something. I don't remember.

they could probably get 10's with slicks.

id like to see it happen on 18's. With slicks, its pretty much a given... 550rwhp is more than enough for 10s on slicks with a full weight 370z.

Can the axles handle slicks? I know the 350 could only handle about 400whp on slicks.

That's been my question all along. Not sure how much the rear end can take before it grenades.

I'm not as familiar with the r200 variant in the 350, but the z32 version was near bulletproof. I believe the 350 version is notably weaker, but not sure the actual limits.

The axles are a definite weak spot though. I hear cv click from guys that just street drive FI setups. I can't imagine theyd hold up to much on slicks, but you never know unless you try.

The rear ends and driveshafts will not break.

The axles are not the strongest but they can do it. Its not a bad idea to keep a spare set around. The axle clicking has nothing to do with power, most stock Z's do it. My 350z and 370z both did since brand new.

Just launch careful and you will get some life out of the axles... preload them nicely and dont just plain drop the clutch. If you are going to be serious about drag racing, make sure you bring a spare axle and tools to the track, or a trailer.

I've never seen a 350/370 launch hard with slicks on stock axles. The guys at dss (who built my axles/driveshaft) don't recommend the stock axles for slicks at any power level. Most guys I know go to aftermarket assemblies not far beyond 400, even on just dr's.


There are two types of cv click, and frankly, neither is normal. One DOES often happen in stock cars though.

Plenty of guys run stock axles and just bring spares. I wouldnt recommend drag racing on stock axles or DSS axles if you want to keep them in 1-piece... but its just part of the game. A bad launch breaks the DSS axles all in the same, they can just take a tad more. If you are soft enough you will get down the track.

Axle clicking definitely isnt normal... just saying its unrelated to power. My 03 350z left my hands this summer with the original axles still in it, clicking away as they did when new. After countless sets of wheels/tires including 2 sets of drag radials, half a set of slicks, and always R-Compound tires for street/DD. I was mostly a street racer, so no sub 1.8 60's for me... but plenty of hurtful nasty wheel hoping launches occured over the years and they held up.

I still say just preload it nice and dont lose your cool as you release the clutch and keep a spare with you, and you will be fine.

Carrying around spare stock axles is a band aid at best, and really only makes sense if you don't plan to track hard more than a handful of times.


I dont know where you get the idea that dss stuff belongs in the same discussion as stock parts. They're warrantied for drag, and I placed quite a few 9 second passes on my r200 with lvl5 axles....three transmissions (an Aussie dog box included) later, still kicking

My take on it was that they should be able to if you drive/launch proper. You think people should upgrade them first. Not a bad idea. It doesnt conflict with my opinion. I just think the stockers could pull it off.

Personally I will just replace one if it breaks. Its unlikely that breaking an axle is going to damage any other part on the car, so thats a $2000+ upgrade that I do not mind waiting to spend until it is a problem. But I am not trying to stop anyone from upgrading them first if they feel it is unacceptable to run the risk.

BTW when I saying that DSS axles break just the same... I was refering to people I have known that broke the other levels in a 350z/G35. All they offer for the 370z is their "Pro-Level" setup, which I have never personally heard of anyone breaking. So for as far I know, the only solution they list for the 370z may be "bullet-proof" for the most part.
