Are you guys also moving the gas tank?

No not at this point. I am putting in rear lexan and building a front splitter I cant speak for anyone else.

for now I'm keeping the stock fuel tank and trying to mod it so we get the fuel starvation under control... I plan to eventually use this car for wheel to wheel racing and when I do will have to change over to fuel cell... no rush

it'll probably be next week before we have a new weight

Curious to see how the weigh in turns out.

Same

Travis, is Redline still going to be working on a brake duct kit? No rush but I plan on doing that this winter, so if Redline decides to make a kit for it that would be fantastic. I think I've sold myself on the AP racing brakes as well, I'm sick of the problems with the stock brakes.

They are definitely building a 'kit' for my car, so I don't see any reason why they wouldn't resell it to you all. I'll ask Robert at Redline... and if he's monitoring this thread, he can respond

RCZ do you have the cf parts yet??

Travis what does the car weigh??

BanningZ your avatar is sexy

Any updates Travis?

I wish... my mechanic has had the car for three weeks, and he recently wrote me to say that he has some kind of sickness that has kept him out of his shop... nothing I can do about it right now... it will really suck if my car is not ready for my next event... depressed

:shakes head:

Sucks to hear man.

Can't wait to see that car back on the track Travis.. Hopefully your guy is getting better..

Dammit. Had been wondering what the holdup was. This is one of the best threads on here...

Travis, if you need a harness bar PM me, we have made our own that looks great and works well. It bolts up in the same stock position. I use it on my 370 Z race car. We've designed our own carbon fiber splitter as well if we can help with that.

Our first track day was at Button Willow for the Super Lap Battle where we took second with a 2:00 time on a completely stock motor. The car had cannards on it with our splitter and our wing with a KW suspension. We just finished the Red Line Time Attack at Cal Speedway and took second again behind a more powerful 370 Z...him 1.55.5.....us 1.55.6. Tires NT05's 285/35/18's squared with spacers using BrakeMan brakes.

If you're looking for down force or suspension needs we can help as well. We're in Calif.

I can't wait to see your final package as that's the direction we're headed.

We should have a supercharger on the car soon. We're a race shop only for fabrication and suspension needs. Maybe you've heard of us, ROBISPEC.

Awesome thread by the way with great detail!

We'd love to help you achieve your goals!!


:tup:

Nice to hear from you! Priority right now is just to get the thing running... But yeah, we should talk at some point and I will PM you after I get through my tgiving event.

Already have a custom-made cross-member that my cage fab guy built.

We are working on a custom front splitter as well... would LOVE to see pictures of how you set yours up!!! Feel free to post here.

Congrats on your successes so far! Sounds like you came in just behind Paul at AE??? How do you like the square tire setup ? I thought about doing that but ruled it out b/c I feared it would throw the balance off and create too much oversteer.

Also, can you share which supercharger you are pursuing ?

Rgds

Thanks for the invite to post I LOVE THIS THREAD

hows this look for how to keep the car nailed down with some sexy functonal aero?

Note the "sub sacrificial splitter " (white) bonded to the carbon honeycomb one.
the bolts you see are bolted directly to a subframe we built which is bolted to the chassis. You will need to drill and tap 4 holes in the bumper beam and 2 in the front aluminium core support subframe..easy mods if you know how to use a power drill ;-)

On the "square setup" if you do it right it can be very forgiving...we were the only 370 with the throttle pinned through 1&2 at AAA speedway...(at least the other 370's said they were needing to "breath" the throttle a bit) We had the least WHP and the most Aero (= drag) so this might have been why I could be so "brave" in 1&2 (but as a chassis setup shop I want to believe it was due to the superior setup!) as we were the slowest entry speed of the 4 370's (but the fastest exit speed) got to love cheap radar speed detectors.

Yes 2nd by a 10th! Paul worked hard for his win .....though lol
Rotrex Race only kit as we will be using the space where the A/C compressor lives...

Did I just read about a potential S/C build?

Thanks Travis!

I see Robi has already responded and he's much more capable than I to share what we're doing. It's always refreshing to compare info between fellow racers with a common goal in mind.....to be very fast AND safe!



Thanks for the invite as well Travis and best of luck with your build :tup:

Z06Stan ;)

Yes you did...it will be a race part only with zero concessions for street...like the first thing you need to do is remove your A/C unit! lol But it piping and FMIC will be second to none as to effecency and charge density.

I love race only parts, it helps you weed out all the *******.

All, with somewhat scaled back ambitions / expectations, I will be running in my local NASA TT event this weekend... stock steering, no rear diff cooling, etc... but the car should be a go!

Thanks to Junior at Fathead Fab for stepping up to help me get ready! So far, he's already managed to get the computer situation figured out (there was a disconnected throttle position sensor)... now need to do some final tweaks on seat, replace oem steering assembly, mount new side mirrors and add back in requisite safety equip

Will have an updated weight to report next weekend!

Robi and Stan... the front splitter looks perfect ! if you have the time and inclination would love to see more pics of how you constructed and attached the 'sub frame' and what materials you used etc. Okay to post here or start a new thread. Also, I'm definitely in for updates on the SC! :)

You got it and thanks!

Great news on your end by the way and best of luck at the races Travis :tup: Keep us posted on your race results.

Which mirrors did you go with? That's on our list as well. We should have the OS Geiken (sp?) diff in this week with the cooler. Right Robi :icon17:

Z06stan

Robi folks, I too would be interested in purchasing a splitter

hey stan, the mirrors are generic AP Racing side mirrors... we will affix them to custom polycarb window fairings that occupy the front 1/4 - 1/3 of the side windows... not sure exactly how it will turn out - junior's working on it this week

Good work fellows! Travis, good to hear you'll get to run it this weekend an feel out the new mods.

Sooner or later you're gonna need a truck and a trailer to get that thing around - lol

well, we're actually touch and go again for the weekened... fingers crossed

yes, you're right about the trailer... trying to postpone that as long as possible, but eventually I won't have a choice... hard to keep a car like this street'able

Hope you at least get to try it out this weekend. It will be good to see how it's coming together...

up till 2am last night, got everything working except when i got to the track this morning, couldn't get the brakes and turn signals to work ! so now i'm home... going to nap a couple hours then try and figure out what's wrong... it's not the lights themselves (tested)... not the brake position sensor (tested... and turn signal doesn't work either, nor hazards)... not a blown fuse (looked)... i am getting voltage coming off the brake position indicator (on when brake NOT applied), but haven't traced it to see where it goes and why things don't work after that... any ideas would be greatly appreciated, ie if someone has studied the wiring diagram... will check in after nap :)

so... I did something stupid... Decided to get aggressive and de-pin the main harness behind the panel... I forgot to mark on of the branches going to the primary gauge cluster and ended up de-pining that one !!!! ... It's fubar and I'm going to have to order an entire new harness... I'm certain it's going to cost a crap-load... if anyone knows a dealer that can hook me up, please drop me a PM.............. UPDATE: I'm looking for the 'Main Harness' which is Nissan Part # 24010-Z34006

FYI, car with driver and full tank of gas weighed in at 3260 yesterday... that'd be sub-3,000 without driver and fuel, and after roll cage and all accessories installed... and it is BEFORE removing A/C equip... I'm expecting that to be another 40 or so pounds... we'll crown the victor of the weight guessing contest after a/c is removed and car is back in working order

Oh snap...I wasn't too far off then lol

you were close!

not declaring a victor until we get the a/c out and I weight it with 3/4 tank of fuel, but looking like DannyGT right now... won't have the answer for a couple weeks, unfortunately because I'm now waiting on a wiring harness before we do anything else !

Just depends on how much you and the fuel weigh together, really. I guestimated no driver and low on fuel.

That really sucks about the harness. It sucks about the lost weekend too - I assume you lost your track fee on top of it all... :(

Nice to year you're under 3K on weight with the AC out. Is there anything else on the list for reduction?

This means we also all have to wait for weeks to see track videos. Bummer. At least the car should be in ship shape when you get it out there...

Thanks for looking on the bright side of things! trial and ERROR is part of the process of course! :driving: we've got some great vendors on this board helping me work through issues like this and I can tell you that I'm getting lots of coaching and input from my sponsors at Forged Performance and DoubleDown Motorsports... and Junior (Fathead Fab) is anxious to start on the next leg of work which we'll kick off in mid-Dec... not sure if I'll get any more track days in in 2009, but will damn sure be ready by Jan

I did have a chance to drive the car to/from the track and I could definitely feel the increased chassis stiffness even only pushing it at 2/10ths. Can't wait to open it up!

Also, would like to share with you all that RobiSpec will be supplying my front splitter assembly and canards. Instead of the carbon sheet he offers, I'll be using the 'boat board' that we already purchased for the splitter, but I'm a big fan of his sub-assembly and front air damn... a great turn-key solution for all of us to consider... more to come

To answer your question on weight beyond the a/c... YES... my pounds / HP ratio limit is 8.7. That means that if I optimistically end up with 330 hp at the wheels, I can be as low as 3,000 lbs competition weight. Which would include 300 lbs of driver and fuel. I'm 180lbs off that mark now, and assuming a/c weighs 40lbs and all the aero I'm adding weighs about the same, then 180lbs is my remaining target. There are folks on this board with a lot more experience on how to get at the last bits of weight, but I'm confident that over time I will get at most of that. Heck, if I could get it below that # would allow me to strategically add back for more ideal weight distribution. Some of the weight savings opportunities I'm considering:

- swap HFCs for straight pipes and and CBE for something lighter... maybe 20 lbs
- de-pin wiring... maybe 10-20 lbs... yes, will be more careful next time or have someone do it for me ;)
- swap rear window for lexan... not yet done... 10-15 lbs
- car was weighed using stock wheels/tires... should be 5-10 lbs less with competition setup
- enhance fuel system so I can run with only what I need for a session... could be good for 80+ lbs !
- cut off more unneeded sheet metal, unused mounting points, hangars, etc
- eliminate unused bolts and fasteners... 5-10 lbs ?
- look for more weight in engine compartment... haven't done much at all there... maybe cut some of the material in the hood and swap latches for dzus fasteners... no idea yet

Nice list. I think the engine compartment is key - the weight distribution on this car is so screwed up, anything you can take out up there helps. I'm not sure what the stock alternator weighs, but there are some pounds to be saved for sure. Not the cheapest reduction, but it could be worth it at some point...

Also, have you gotten rid of anything in the front bumper (I'm too lazy to go back and check)? Weight out there is the worst for both polar moment and overall distribution - it's the first thing I would try to reduce, as long as you keep all appropriate crumple zone hardware intact. Bumper shocks can be replaced with tubes. Rear bumper crap is are even easier to ditch - you're pretty unlikely to hit back first.

Other thoughts (not sure how many of these you've done):

Headlights? (probably not if you're still driving to the track)
Aluminum oil pan? (assume the stock one is steel) - not cheap
Aluminum master cylinder
Lightening holes in non-essential supports
Fender liners
Washer fluid, fluid bins, nozzles, misc. plastic crap, etc...

Custom aluminum brackets can be pretty easy to make to replace heavy steel brackets, as long as they are not in a location with excessive vibration...

Travis are you going to TT or SC your Z
