So, Jim, do you believe that your current injectors are big enough for a good tune on E85 and small enough for a good tune on gasoline? I have been wondering if that could be done, as I want to run E85 but also want to be able to make long drives, which I cannot safely do yet with E85 due to relative scarcity of the fuel.

Hoping you start hittin' that pipe again. :wink:

Yea, the 75's work well, I had them running at stoich on pump gas in just a few seconds. They are pretty much maxed out on E85 on my setup, but maintain about .8-.85 lambda at 100 % and WOT. Do I need larger injectors? Technically, but E85 is so forgiving and runs so cool I've never had a problem. Plus I only run around 26-28 psi on the street anyways. It's kinda the sweet spot. the injectors are happy, the transmissions happy and I'm happy. Anything above that is just asking for a trip to jail.

Yea Tox, I'm sure I'll be hooked and going every year from here on out. I'm already thinking about a dedicated steamboat car for next year. 8)

I think you should just build 'guard rails' around the pink rocket and throw an MC engine in there. You could throw it into all the snow banks and keep some of the low end grunt for the low speed ice corners. 2" square tube would do nicely ;-)

It probably will be the pink car, I'm thinking V8.

Getting shitty gas mileage on this stuff sucks...I didn't do several fall drives this year as they said mileage was around 250 and my car can't go 250 miles per tank if you're beating on it the whole time :( . I'm starting to try and think up 'back up' solutions for running safely boost on 92 for road trips...sticking to 6psi and worshipping the knock light is sounding like the best option for now.

What's the power difference like with water injection hooked up? Without it? 5-10% on my car is like 10-15hp...with yours its like 60 or 70 :wtf:

Just got done replacing a blown header to turbo gasket. This has been happening about every 6 months, and every time the turbo has rattled loose. I'm pretty sure the motor is moving around so much that the DP is hitting on strut upright.

So, I while I was at it I did installed the poly Mustang tranny mounts from Energy to keep the motor under control.

It felt great to drive the car again, the mounts add a little noise, but it's kinda a low growl when you really get on the gas. It's pretty cool, I like it. I'm just glad they are finally getting around to clearing the streets around here, the yellow car would not have done so well with the VW size pot holes and ruts that formed in the ice. I guess thats what red car is for :-D

BTDT on all accounts. My solution was to machine the turbine housing and header and use no gasket. If there is no gasket there, there is no gasket to blow out

No leaks either.

The reason the gasket blows out is because the nuts are getting loose on the studs, the solution is some 2600F loctite, all we use around 034 these days, work well and prevents this from happening.

huh, didn't know loctite made anything good for that hot?

audifreakjim · Post by **audifreakjim** » Thu Jan 04, 2007 10:18 pm

Good stuff, I'll have to try the loctite if it happens again. I like the machining option, but that would require extra work. :wink:

Machining option also doesn't address the loosening fasteners, granted, doesn't necessitte turbo removal for replacing the gasket (just tighten it back up assuming the turbo doesn't fall off), but the real problem is the loosening, trust me, once you fix that problem, a gasket will last forever.

what type of nuts are you guys using that loosen?

audifreakjim · Post by **audifreakjim** » Fri Jan 05, 2007 8:21 am

Copper plated self locking manifold nuts

IME It's been more an issue of the stud itself backing out of the flange than the nut loosening.

Yup, Nate's right, put loctite on both the stud and the nut :thumbsup:

audifreakjim · Post by **audifreakjim** » Fri Jan 05, 2007 11:24 am

Yep, half the time the studs come out with the nuts, and it takes some real effort to get the nuts unlocked.

Derracuda · Post by **Derracuda** » Fri Jan 05, 2007 11:42 am

you don't have the studs locked from the backsides with extra nuts? javad reccommended that to me a long time ago

:slap: There is no back side silly.
