    L6 Turbo Header Group Buy

    in Group Buys

    Posted

    Glad I didn't buy the other header the guy had that sold it to you.....sorry to hear about the fitment problems - I know that's a bummer after you dropped $800 on the header. Crap-ola!

     

    No need to be sorry. :beatdeadh:violin:I'm moved on and already planning my next upgrade. My goal is 500rwhp on pump gas. :D. I'm at 454rwhp on race gas now so what's another 50hp...? Actually it's a lot but you gotta have a goal.:burnout:

    Now back to the topic...

     

    Someone should see if this header is still around. I like the design but am unsure if it would fit.... :roll:

    damn! thanks for tryin jg...so what are your options to get it to fit your car?id like to see it installed and in your car if/when you ever get it completed...as well as dyno info if youre able...thanks again for the effort

    I just need to modify the pipes so the turbo moves closer to the block. I'll also be changing the wastegate flange. If I'm taking the time, I may also redesign the header for use with a divided turbine housing. This coupled with a new, more efficient ball bearing turbo should improve my boost response (hopefully by 500rpm) and allow more peak HP.

    John, your the best. I sincerely appreciate the effort and sacrifice. Best of luck with your build.

     

    yeah, thanks for trying man.

     

    Thanks guys. It was a worthwhile effort. The header purchase is not a complete loss. It will just take more time and expense to make it perfect.

     

    Guess it would have been good to get one that fits... thats to bad.

     

    That's b&%ch about this whole mess. The header was suppose to fit. I'm still unclear on what car my header was built for, certainly not a stock body S30 or S130. The inner fender clearance is way off. The only thing I can surmise is that it was built for a race car with no inner fenders and possibly a tube frame.

    Update: SSAC just responded. They have officially declined my offer to modify my turbo header for use as a template. My involvement with this project has also come to a close. I did my best to help the group and to ultimately help myself but it's all been for not. I will modify the header I purchased to perfectly fit my car but I'm not sure when or at what cost. I wish you all luck on getting this group buy up and going again.

    Smoke On Deceleration

    in Trouble Shooting / General Engine

    Posted

    Yup, it was probably oil coming up the PCV valve and the left hander spilling the oil into the intake runners.

     

    HBZ member "hughdogz" uses a PCV oil separating tank that would solve this. Take a look at the below picture of Hugh's engine. You can just see the hose going the the tank next to the master cylinder. Maybe he'll chime in and give us more details.

     

    BTW, Hugh's engine is even more beautiful in person then it looks in the picture. :D

    Smoke On Deceleration

    in Trouble Shooting / General Engine

    Posted

    During a recent track day my turbo L28 would billow smoke after a HARD downshift and sharp left turn. The turn may have nothing to to with it. Strangely the smoke came out a few seconds after the downshift and happened to be while I was in the turn. If I downshifted to say a peak RPM of 4K there would be no smoke on the same turn. My engine is practically new and doesn't burn any oil or smoke at any other time. I attribute the smoke to high vacuum pulling oil from either the valve cover or the PCV.

    I just sent another email to SSAC requesting a reply to my email sent on 9/23. So far I've gotten no response. I basically requested they pay for all shipping them modify the header so it's suitable as a template. This would be in exchange for the $400.00 reimbursement. If this drags on much longer I will end up paying for my own mods on top of the $800.00 I've already spent. I'm regretting ever getting involved....bah! :icon55:

    DC Water Jet's 202mph Z-Car

    in Windtunnel Test Results and Analysis

    Posted

    The guys at DC Water Jet broke another record at over 202 mph during Speed Week this year (8/08). I think this photo bears some scrutiny for what they have on it compared with what the Aero Testing Revealed. From the prior records on the fender you may or may not be able to see that this car has gone 221 mph in the past... Real speeds verified and registered. It's kind of shocking when you look at the car in the light of what the testing revealed.

    I mean, this car is going a good 30 (to 50!!!) mph faster at Bonneville than our slicked-up 2+2 with a G-Nose and the light covers, blocked radiator inlet, and full belly pan.

    They are running this year in F/BFMS, which is 3 liter (F/), Blown (B), Fuel (F), Modified Sports (MS)...which MS is the class you run in with a 240-280 that has non-stock body mods, after that all the other stuff should be self explanatory in the class.

    So take a look at what they are running and comment as you will.

     

    All I can say is it's take a bunch of horsepower and extra weight to overcome poor aerodynamics. The front end is literally shaped like a brick. Here are a couple of pictures I took of the car at Speed Week 2007. It was a little more shapely back then.

    L28 dyno

    in Nissan L6 Forum

    Posted

    :2thumbs:Cool! I noticed the on the second sheet that the ambient temp was 98.21F. That is seriously hot for a dyno pull. :shock: Your IC was working hard I bet. I also was impressed that the engine pulls so well up to 7K RPM. The curve is very broad for an L28. No wonder it does so well at the track. Is your cyl head ported or ???

     

    I wonder what the dyno sheet will look like with lower ambient temps and a 12:1 mixture? :D

    Bad Break up(Resets,Grounding,Noise Problems)

    in Megasquirt

    Posted

    Jeff read through this:

    http://en.wikipedia.org/wiki/Electromagnetic_Interference

     

    "EMI or RFI may be broadly categorized into two types; narrowband and broadband. Narrowband interference usually arises from intentional transmissions such as radio and TV stations, pager transmitters, cell phones, etc. Broadband interference usually comes from incidental radio frequency emitters. These include electric power transmission lines, electric motors, thermostats, bug zappers, etc. Anywhere electrical power is being turned off and on rapidly is a potential source.

     

    My thought is, if it is happening now, maybe you've moved your plug wires around (bumped) and now they are causing the issue.

     

    When you cut the harness did you move anything else?

     

     

    Is it just me that noticed this or does Megasquirt seem to have an inherent problem with EMI? I've read about several problem MS installations that exhibit similar symptoms. The recommendation is often "fix your EMI problem". Why don't other standalone EFI manufacturers have a similar issue? I don't mean to thread jack but the EMI issue comes up often.

    280zxT cv shafts BROKEN !!

    in Drivetrain

    Posted

    Hi all.

    Can ANYONE tell me what other options I have to keep my rear shafts from shearing off?

    I converted my 81 280zx U-joint half shafts to turbo cv's .

    Still breaking at the track,on a street radial,and no burnout.

    I am shearing the shafts righ off!!

    Help!?

     

    MAXIMUS,

    Did you ever get your CV Shaft issue handled? Just curious what solved the problem.

    Two Shuttles Ready To Go

    in Non Tech Board

    Posted

    First and only time ever to have two at the pad ready to launch. The upcoming Atlantis Hubble repair mission will go into a higher orbit than can be supported by a space station refuge, and per NASA rules Endeavor must be ready for a rescue if required.

     

    Altogether apart from being my longtime job, I love these magnificent, overly expensive, and complex ugly airplanes - Sadly, I think most of the US public is Ho Hum about our manned space efforts. At the risk of getting too political, NASA spends about 0.5% of the national budget, and the returns in terms of scientific advancement and national prestige are well worth it. [End of infomercial]

     

    I get chills every time I see a launch. Having two shuttles ready to launch is an incredible site. Let's just hope they don't have to use Endeavor.

     

    Thanks for sharing Rick.

    I am at 22 psi and use 7s.

     

    Magnecor plug wires are great (I am running a set as well)m but they are a little pricey. I paid $80 for mine, and they are only 6 inches long, tip to tip.

     

    Wow... are you saying 22psi on 91, 92 or 93 octane pump gas? My car would break the ring lands from detonation. Are you using methanol or do you have a ceramic coating on your combustion chambers or pistons? Please tell me your secret..

     

    I run BPR7ES at 15psi on the street and BR8ES's at 26psi on the track. I find that the 7's with the projected electrode start better cold and probably get a bit better mileage. Factory plugs are BPR6ES-11's. I highly recommend a resistor plug no matter what.
