Hi Folks, I am installing my wideband O2 gauge where my clock used to be. The location work well for me but the red LED's are far too bright at night. To solve this I want to find a piece of dark Plexiglas and cut a circle to act as a nighttime lens. I know this sound a bit hokey but it's seems like it would solve my problem perfectly. Any idea where I could get a dark piece of plexiglas? Most shops want to charge big $$$$ for a whole sheet, sometimes as much as $50.00 - $100.00.

Thanks for taking the time to provide this info.

Thanks for the nozzle recommendation. I just called Cooling mist and I do need a valve for each "controlled" nozzle. I could use one valve for two nozzles but they would be not independently controlled.

Below is how my Tec3 GPO's (General Purpose Output's) work. They use PWM and are compatible with the frequency of the Coolingmist setup. Are you saying I may need two or more nozzles? If I understand correctly, the Coolingmist kit comes with one valve which can control one nozzle. If I want to control two or more nozzles I would the same amount of valves and a separate PWM signal for each valve. Am I on the right track? I might have two GPO wires from my Tec3 still available. If I need a separate PWM signal for each valve I will likely be limited to two.

Bernardd, I found this setup that looks like it's just what I need to hook it into my Tec3. I would need to buy a tank but other than that it looks complete. Do you agree? http://www.coolingmist.com/detailmain.aspx?pid=shsvecu

Great responses everyone. Thanks so much for taking the time. Now I need to digest the info and get going with a system. I was originally thinking my Tec3 could control the methanol injection but I was told that that would be undesirable by a methanol injection vendor. I'm now more convinced that using the Tec3 to control the meth injection is the way for me. I'm sure I'll have more questions as I design the system but for now this thread has been a huge help.

Joel, Is it hook and loop or pile?

Aux, Can you post a list of what each gun is? Very nice BTW.

We definitely need to consider folks with A/C. I'm one of them... I vote for a flange that's aft of center but not nearly as far back as the old BRE manifold. It probably could be a bit forward of the OEM L28ET manifold.

I recommended the 1 5/8 OD primary with a 1/8" wall. This size will support 700+ bhp and is small enough that bolts will clear properly. This size should also allow us more flexibility to get closer to equal length. I'm in favor of larger primaries if it's possible but it will likely result in a header more like a log manifold. I vote for the second order of business to be complete.

Congrats Bartman!!!! I officially hand the baton off to you since I was picked last issue..

My opinion is you should definitely get an intercooler first then add methanol injection if needed. An intercooler is a core component to any well built turbocharged engine. Case in point, look at all the OEM engines with turbo's. Most have intercoolers with no other charge cooling mechanism. Methanol should considered only if you can't run your desired boost with only an intercooler.

Hi Folks, I'm in the process of deciding what methanol injection I want to put on my turbo L28. I thought I would do 100% methanol injection but there is varying opinions as to whether that is safe, necessary or even harmful to the equipment. Some manufactures say you get the most benefit by going with a 50/50 water/methanol mix. Personally, I thought straight methanol would be best but now I'm not so sure. My goal with the new system would be to protect against detonation at high boost levels while using 92 octane pump gas. Also I want to bring down my exhaust temps. What's everyone's opinion on straight methanol vs a 50/50 mix with water? Also, where are you getting your methanol?

I agree. T3 or T4 should be an option. There is even a flange posted earlier in this thread that would do both. Secondly, big wastegates are typically used when you have a relatively BIG turbo for your application and want to run low boost like 10psi or so. We should have a couple options here as well. I need 40mm but I can always modify if the masses want something different. For the tubing I highly recommend 1 5/8 primary OD with 1/8 wall mild steel.

Dang Joel!!!! You beat me to the punch. If it doesn't work out, let me know.

I've read the HBZ post that claimed a stock Z06 can do 10's on drag radials. Personally all the ones I've seen race weren't even close. I even raced one with a supercharger and meth and it could barley get into the 11's. This is just my experience. BTW, I'd own a Z06 in a second if I had the $$$$.

That's impressive to say the least. He dogged it off the line and still ran an 11.1. On the 3rd run they ran 126mph. I'm guessing that's about 550bhp and on 93 octane pump gas.

I'm also looking into a possible doaner. Stay tuned....

The good news is that the new header design should have flow improvements over the SFP (log style) design.

So we agree???

I did some more research on what the primary size should be on the proposed turbo header. A turbo L6 and an NA small block Chevy are not comparable. I have it on good authority that a 1 5/8 primary OD with 1/8 wall mild steel is still the best way to go. The SFP header has this identical primary size and has allowed over 650bhp on at least two L28's that I'm aware of. 1 3/4 and larger will likely be too big and wouldn't allow the studs, washers and nuts to fit properly. Personally I want a T3 flange because my next turbo will be a Garrett GT35R. I will not go past the HP potential of this turbo. I believe the Garrett GT42R is a T4. The Holsets might be a different story. Someone please jump in and school us on what turbos you would use on an L28 that have a T4 turbine.

Fairly new. It's been up for a few months I believe. I had the same reaction as you when I first heard.

Nice find!!!!!! Gives me chills just thinking looking at it.

http://www.rottentomatoes.com/m/speed_racer/news/1726473/ The two cars that weren't in the list that should of been were the 55 Chev in Two Lane Blacktop and coincidentally the 55 Chev in American Graffiti... Two Lane Blacktop is a B movie but a great car flick none the less.
