I am a Brit, but have lived in Ecuador for 25 years. If you send me your email, I Will send you some photos of H2 in Ecuador, including one that was on the cover of the Moss Motors H2 catalogue a couple of months back. What is the max size of JPG file you would like?

Hi Michael
You should have gotten a PM with email to send pics. JPG size does not matter. What ever will get best quality pic.

I suggested the 160 degree Tstat as even though supercharger runs it's cooling system and engine it's own temp coolling system You are running a supercharger. Even though 210 is Ok You would have a little more cushion of cooling should You pull a load on occasion. Also it has been a while since I studied it but, I think water in a closed system will boil quicker at higher altitudes. Please forgive Me if i wrong on that point. It just seems I remember that water boils more easily at higher altitude in My studies before. Had been thinking about building a stock H2 with upgrades to run Pike's Peak in a near future year. Have full table for 2007. But, just been doing some research.

Anyway beside that it in realm of performance it is good to have a safety margin. With a programmer You can tell computer of the cooler T-stat and it will advance timing a little which will in turn gives You a little more HP and torque for when needed to make the high climbs in moutains.

Ligenfelter will not install a supercharger kit without going with 160 T-stat unless they changed policy. The 135 would be to much unless You were going to be running hot laps in desert distance runs or top end speed runs, like i hope to do this summer. Heat is the worst enemy to making power/torque. Heat causes detonation and even though You may not be going for speed etc. You are using the supercharger to improve performance at higher altitudes as they discovered in WW2 it helped the fighters performance at altitude in thinner air and increased ceiling of operation of the planes so they had advantage of coming down with sun behind them. Well a little off way to explain the cooler T-stat but, I believe You would benefit from it from reading the things you did to help solve Your heating problems before.

If You have not You can find pics of My show Queen with search in pics sections. We are having interest for several mag shoots but, depending on what We are doing. Have one that wants to go with us on speed runs, one or 2 that would like some tech articles on how we did what we did on some areas of the H2 and then may do a couple of things with RIDES. It is all waiting on this next upgrade and when Dragon get's it done so We can begin discussing times for mags. With the electronics not done We cannot commit, just do not want to do the mags wrong. Dragon has had some national contacts also for Us. I have begged Him to tell me what it is but, He does not want to until it is done and He can surprise me. I need to kick him for telling Me because i keep thinking about what it could be.

Well Michael can't wait to see your pics and the mag cover shot also. I get Moss and most likely saw it but, do not know if i still have it. I save them for a while then they get hauled out by daughter after a couple months. She gets tired of looking at the mags i read all the time about parts, tuning, all that kind of stuff. I'm searching now to see what is out there in body kits for Chrysler Crossfire as well as pefomance items.

Thanks in advance for Pics Michael. Maybe some day soon I can come down and go on a scenic tour with You in H2. I'm making plans to travel more i hope after first of new year. Hoping things keep lining up good health wise like it is. It will not be long i will be at shop in Dragon's way all the time again. Although as bad as it has been and thought I would never get to go to shop again I think He will be happy when i start showing up bugging him.

You're right about the boiling point of water changing relative to elevation but with a closed system there isn't a pressure differential with a change in elevation (internal to the system) so it's not a factor.

What *is* a factor is the reduced atmosphere at higher elevations and the impact is causes by reduced thermal dissipation. Since the air is thinner at high altitudes, engines can't get rid of their heat so they tend to overheat unless their cooling systems are sized to account for the sparse atmosphere.

Couple that with the fact that volumetric efficiency falls off with low density air and you've got a recipe for disaster.

Thanks Doyle for setting Me straight on the altitude thing. It had been a couple of years sense I read about it.

What size bulbs do you need in the driving lights? Did you have to get new housings for them?

[Michael Baker]

The PIAA driving lights come with the HID bulbs and they simply replace the stock lights in the same position.

Hey Michael,

Nice install job. I also have HID's on the headlights. I also mounted the ballasts the same way you did. The only difference is probably my reflectors. I bought a kit that only comes with the bulbs, ballasts and wire kits so I kept my stock reflectors. And Yes, the difference IS night and day.

Q1: What's the PIAA part number for the DRL replacement?
Q2: Do they just unscrewed off when the hood is in the open position? or did you have to remove the bumper and other junk?

[Michael Baker]

1. PIAA 600 is the part number
2. Was fairly easy to get them off, more difficult to align the new ones - see my original post
