Wow! Please update!

 

Don't be sorry, everyone is entitled to their opinion.

If you are saying throw it away because it is not pretty,
I will agree that it is not, but it is a large improvement over the stock convertor H pipe as far as seat of the pants goes.
I managed to stay in front of a 2011 Camaro at 260+ and it seemed to flow ok for a stock engine.

I will be changing to a larger system down the road when I decide on which SC I will be going with but the local shop straight pipe was the cheapest temp convertor delete.

I am curious as to the decreased O2 sensor life comment and would like to here more facts please.

Thanks,
Brad

 

I am not going to say about the performance one way or the other, but you never want a O2 below the 3 Oclock position due to moisture in the pipes.
All it takes in one drop and it is done.
The more down you can get them the better.

 

Thanks, it makes sence. It was suppose to be centered on the front but they screwed up.

Ive been waiting for a nice coated X pipe but there are to many things that I don't like with what I see out there. What I do like I can not afford

 

I know EXACTLY the feeling.

While yours is not going to make much power, it is similar to the old H pipe that DR sold for years, and frankly they sound better than the X pipes to me.

 

Yes, Greg hit that on the head, never mount the O2 below the 3/9 position. The more to the top of the pipe the better. It does have to do with moisture/condensation.

I could pound off a better X pipe than that in 2 hours!

 

This project is moving back to the front burner. Some developments and random thoughts:

Apparently, my Rennlist membership has lapsed to the point that I can't post photos.

After two years, it appears that I have to relearn _everything._ Took me an hour to rewire TechEdge wideband controller and Sharktuner, for example.

Got the expanded load EZK maps by JDS working. I can now tune ignition even at high loads. The car is currently running retarded by a retarded amount. The idea was to do that on a load dyno. Sharkplotter doesn't work with the new expanded load EZK maps, by the way. [EDIT: Looks like a user error at this point. EDITEDIT: Or maybe not.]

The effin' dyno guy cancelled the appointment booked for this coming Saturday! :-( I got steel lug nuts just for him, and now I am being stood up like this?!!? Anybody know any shop with a Dynapack dyno here in MA?

Low compression engine going in this winter. Dead or alive, the stock engine is coming out. Now is the time to start thinking about the next engine.

Spent two hours staring at a 5.0L crankshaft in the garage. I have some ideas; some own, some borrowed, some stolen... There may be a chance that one might be able to breathe some life into those good old worthless pieces of high-quality steel. Anyone know a crankshaft shop here in MA who has the tools to drill crankshaft oiling passages?

Why is the 928 S4 piston pin so heavy? Does some of the usual suspect vendors offer a lighter but still strong replacement pin for the stock pistons?

 

Apparently, IB woke up to the fact that they hadn't billed any members in several years. I suspect that they hadn't billed anyone that was a paid-up member at the time they acquired Rennlist from JD.

That's at least true for me. I got a notice a couple of weeks ago that I'd need to re-up by 11/14. I did.

Good luck with the next phase of the project. John Veninger or Stan Shaw might have thoughts on where to take the crank.

 

Holy **** very nice... i can only dream, and holy **** at that exhaust diameter, that's approaching diesel territory!

Twin turbo-ing a 928 almost makes me believe an AWD conversion is possible... LOL.

 

You need to get with AndyGTS, he has a Taylor modified 5.0 crank to sell.

I don't know what gets drilled, you can probably find some long threads about it.

 

Oh really? Your EZK load now goes zero-to-insane instead of zero-to-100% ??

Do you have any details or log files you want to share, or should I just try to guess?

Send me an email, support (at) sharkplotter. com

 

I'm pretty sure it has been proven that no amount of cross drilling can save the 2/6 bearings.

 

My EZK load goes to _eleven_.




And I have even forgotten how to post video links...

Email sent.

 

I don't know of another dynapack dyno that's operational, but my go-to guy that I've used for all my cars and friends' that I've tuned MS for, is John @ New England dyno in Douglas, MA.

John's never let me down. And his rollers should count more than high enough for you. And not wallet bustingly expensive either, even for tuning time.

...just an option.

 

Good option at that. Stopped by there today and did a couple of runs. Run into a problem with the MAF boot (again), but that was not the shop's fault. If I am going to use an intertia dyno again, I'll go back to New England Dyno.
