My coolant is mostly distilled water. Takes me 5 minutes to swap. Oil I'll do in 500 miles.

For once, I'm dying for the current tank of gas to go quickly, and instead, this is what I get:

Tamas 06-16-2008 08:56 PM

What the hell... you got 97 miles out of a quarter tank? That must be world record... :Eyecrazy:

mysql 06-16-2008 09:00 PM

it's actually 87 miles, and that is with mostly city driving. 20 miles of that was on the highway at around 85 mph.

I cheated a little tonight, I went into boost (boost controller off) for a few seconds. Hit 6 psi. It felt good.

Tamas 06-16-2008 09:03 PM

Yeah, you must be really cheating 'cause I don't know how can you get even 87 miles off a quarter tank, especially with mostly city driving. Hm... interesting.

mysql 06-16-2008 09:07 PM

I promise you, no cheating.

Since I have no cat, the AccessPort with Jeff's maps removed the "cat saving" feature of the pcm that dumps fuel to cool it down during light throttle. What I don't know is if the new housing/seals are helping me too or not. I rarely ever baby the car when driving, so it's hard to determine.

If I really wanted economy, I'd drive it with less throttle from stop lights. Right now I'm mostly just avoiding boost.

Tamas 06-16-2008 09:10 PM

Ah, that makes sense. Cool.
Makes me want to replace the cat with a high-flow one that handles heat better, so the same change could be made. Wonder if such a cat even exists.
But then I wouldn't pass smog here :banghead:

paulmasoner 06-16-2008 09:14 PM

damn J thats good!

you can pass smog with a high flow cat that will take the temps.... look for TeamRX8's old cat info.... VERY pricey though... VERY

mysql 06-16-2008 09:21 PM

your stock cat can handle it. It just might not last to 100k miles :)

paulmasoner 06-16-2008 09:22 PM

:lol:

might not last 500 even...

Sorry for the minor threadjack..

but realistically what is the CAT life expectancy when you factor in Jeff's maps that remove the CAT preservation?

Brettus 06-17-2008 12:35 AM

19875 miles

fahrfegneugen 06-17-2008 12:36 AM

Very cool, so you reused the e-shaft?

Probably less than 120k and more than one afternoon.

Why not?
Its not like it wears out!

fahrfegneugen 06-17-2008 12:57 AM

Just wondering, don't need an exclamation point! :)

How long did this take? and how much? I might buy Phils Turbo kit off him next month :smoker:

SideOfBacon 06-17-2008 09:07 AM

nice to see the work performed by Charles. This really gets me feeling comfortable being he is going to do the MM/BHR install for me upon purchasing. I have heard the stories of quality/great work, but to see it is a whole different story. precision, care and accuracy went into the whole project.

The first post details duration, and a turbo kit has nothing to do with a rebuild.

The rebuild is a lot more involved than a turbo kit install... so yeah, this should make you feel comfortable :)

The turbo install is nothing more than messing with the exhaust manifold, and connecting some pipes in a very small cramped area. There's more to it, but that's what it boils down to.

With the AccessPort solving our fuel management issues, everyone should go turbo. There's no reason not to.

Razz1 06-17-2008 09:23 AM

What!
You didn't replace it with the HYMEE Super Charger?

So............. over heating caused the housing crack?

Yeah, running the rx-7 plugs in leading. Right now I'm using OEM trailing plugs in trailing position because I couldn't find any 2mm shims.

I have never overheated.

I'm keeping the front iron issue on the down low for the time being.
