Thanks! the wiring was the biggest poa in this room... some high voltage for under-cabinet lighting, then of course 1/4 mile of low voltage for speakers and so I can plug in media and controls from different parts of the room... the receiver, computer and xbox are in a media closet for example, so all the peripherals feed in through USB over cat 5

*EDIT*

Just realized you have Stillen HFC's, i guess they don't come with mounting points for the bracket.

Seems as though DDM left this bracket off (pic below). Is it needed? Wouldn't it help rigidity?

I did the same thing.

Update... car is now Supercharged and running! Tuning hopefully tomorrow... everyone keep in mind that we will be DE-TUNING my car for a target weight/power ration, so don't expect big numbers. The goal is flat curve and 380-390whp

ChrisSlicks 12-28-2011 06:59 PM

Very nice!

SPOHN 12-29-2011 05:36 AM

I know this sounds dumb but will that effect TQ numbers also?

Yes. Because HP is a "function" of torque, that is, HP is just torque multiplied by RPM. That said, because they are only using the peak power in the calculation you can try and bend the curve a little and have a mid range boost without it being counted against you.

stoked to see how it runs for ya! should be an absolute blast to drive with ~380whp and a flat power curve

That's awesome, Travis. Hopefully it works out well for you. :tup:

Shamu 12-30-2011 02:18 PM

Cool! i will be very interested in how it works on the track. im debating on whether i go FI and have been waiting to see a serious track car to go this route to see problems. i dont like forging new ground $$$$$.

curious what are you doing to detune? A motor that has good flat power curve may actually outperform a peaky motor on certain tracks. Certainly better in traffic. only time peaky motors are good is when you have lots of open track in front of you with no one to slow you down.

A few things... 1) motordyne intake manifold helps a little bit... 2) we are using the biggest pulley for the GTM SC II kit... 3) uprev tuning... and if we have to sacrific a bit of RPM upper limit we will...

I'm no expert on tuning so it's kind of finger's crossed at this point. We'll see what Jack at HP Logic can do!

Motordyne helps with the detune?

It should not make as much peak power as the stock one but might help to flatten the curve.

Speculation or proven with dynos?

Specuroven.

That's what I'm getting from it, as it seems like the M370 manifold loses top end (but gains mid-range), at least on all of the dyno charts I have seen.

wstar 12-30-2011 05:18 PM

^ What he said. Generally on NA cars the M370 helps flatten the curve a little. More low end, less top end. There have been lots of charts on this for un-tuned, stock cars. I think the big question that's been hanging in the air forever is whether the M370 does anything at all if you're going to dyno-tune with UpRev, as the gains from tuning and the M370 seem to overlap on NA.

Also, Travis may be the first to document trying it out with a supercharger, so it's all new territory.

I have the Motordyne and TT.

I never did a dyno with and without the m370 but I have never seen any set of dynos to prove what the M370 does with FI.

Good question, gents.

Not sure if we will be able to dyno with the stock and M370 because I have the stock piece with me 3 hours away from car... but that's the theory we're going on... yes, in NA, M370 = *slightly* flatter curve, which I think it pretty well documented in Tony's thread...

I'm wondering if there's something I can do with the exhaust as well to flatten out the power delivery

My gut-level instinct would be to downsize your exhaust flow a bit to match the desired peak. In general that seems to be the directionality of these things. Within reason, an oversized exhaust will give peak gains and cut low-end torque, and an undersized one should do the opposite.

IIRC you are running a single-exit... you could play around with an H crossover ahead of where both your pipes collect into the single. Sort of like a NASCAR short-track setup where they are trying to maximize low-mid range power.

It has taken 2 evenings but I read this whole thread. Great work. While reading there were several people mentioning warped rotors. Have a look at the attached article. I have had "warped rotors" and fixed them with a power drill and wire brush on both surfaces just cleaning the friction material off. Its alot cheaper than the $400 rotors I was replacing at the time.

^thanks man! always appreciate when folks take the time to read 100+ pages of this!

So, nothing to report on the car.... wish I had some news! will let jason comment when he can

Somewhat unrelated... finally decided that the Ford was too big to be a DD and tow vehicle and got the bug to upgrade... here's the new ride (actual pic)

... any of you guys have recommendations on Tundra mods?

SPOHN 01-07-2012 09:05 PM

Tundra is good to go as is. Or you could gut it and race it also. Lol.

Yup. That's the impression I've got from reading Tundra forums... exhaust doesn't get you any hp gain. Maybe a few from CAI and tune but not much.

TRD supercharger? Can't have the Z be the only supercharged car in the household... :ugh2:

haha! that's truly the last thing on my list right now... I'm hoping 400+ torque will be enough... but if we're all still here posting in a couple years, you never know!

travisjb 01-07-2012 11:11 PM

couldn't help myself... these afe parts are on the way!

49-46008 - Cat-Back Exhaust System
51-81172 - Cold Air Intake System
46-38005 - Throttle Body Spacer

Pretty consistent +35-40 lb-ft result, from what I've been able to find

RCZ 01-11-2012 10:26 AM

^ Damnit travis hahaha

Soo...what happened with the car?

I'm sorry that I was the one who recommended him and got you into this mess.

travisjb 01-11-2012 10:34 AM

hey Raul

...there is some catastrophic failure we are dealing with... I'm not going to get into specifics yet, until we verify exactly what is going on and decide how to resolve... needless to say, I'm twiddling my thumbs and anxious to get my car and myself back on the track

W.O.W. 370Z 01-11-2012 12:00 PM

What happened?

Red__Zed 01-11-2012 12:03 PM

Sorry to hear. Hope you get it worked out

travisjb 01-11-2012 01:36 PM

thanks guys... I really hope to report some good news here soon... we'll see... not going to provide any more details until we have a path forward

Calvin 01-12-2012 08:11 PM

too much page to read thru lol , anyone know what page is it where there's pictures of travis' roll cage=)?

Fathead 01-13-2012 09:01 AM

Search my posts they were posted by me.

RCZ 01-13-2012 09:12 AM

catastrophic failure...yikes. I hope its not of the mechanical type. I'm surprised since both my car and kelly's came out perfect and we had just as much crap going on.

Google image search of "travisjb" and "fathead" has tons of pics of the car and cage in different stages

Junior! good to hear from you... saw the pics of the little guy on facebook... growing up fast!

oleg 01-19-2012 07:17 AM

Just looked at those Google images, what kind of exhaust is that?

Red__Zed 01-19-2012 08:16 AM

Any movement Travis?
