"Elgin Super-Secret Mystery Grind" LOL

 

Jeff did a nice writeup on the porting of his stocker. Once it was revealed it was cast steel and could be welded up, the fear of cutting through anyplace, or being too thin was easily solved with his MIG...

Turned out nice for a guy doing secret work in the garage where nobody was supposed to work on their cars! It was like getting into a speakeasy back in the day. "Knock Knock" (Little drilled hole opens to reveal an eyeball) "That you? Anybody else around out there?" No (door creaks up)  "Hurry, get inside, I'm not supposed to be working on my car in here!"

John,

 

These guys  http://www.lonewolfp....com/prices.htm  also have a service they don't show on their website where they cut the manifold in half, port it, and weld it back together which I understand results in a much better flow than the "standard" porting.

TimO:

Is that for the exhaust manifold? I can see them doing the intake...

TonyD:

Is there a link to the writeup JeffP did for the stock exhaust manifold?

I couldn'see it on his website.

Thanks,

Brad

Exhaust manifold. Hard to find on their website. Go to their prices page and you will see it under Manifold Porting.

I saw the porting for the exhaust manifold already, I was wondering about the cutting open and welding like they say they can do on the intake manifold.

Sounds like you guys need a euro turbo manifold!

Thanks Rossman.

I saw that page but wondered about what he did for the area from ports 1-4 coming into the plenum.

There was absolutely no mention of smoothing or enlarging which is why I thought I may have miss3d a page...

i know this one is out of the league.....

just wondering if a stock L28E .....    will cooperate with a GT30  on 0.82ar ??

going standalone on a fairly stock L28E ( internally - just for now ( low boost ) ) - and thinking if it's gonna spool fine on that ar size ??

any tips would be cool.

 

cheers guys.

I may be wrong, but I believe the .82 on the 30 series is pretty much the equivalent of the .63 on the 35 series as far as flow goes.

It's been a while since I looked at the maps for the housings...

Has anybody but Jeff done the exhaust manifold pressure checks?

 

My understanding is some of the new Diesels have an exhaust pressure sensor available, and if this is true, I can see adding that to a logging channel, or monitoring it with the EMS will pay dividends in the black art of turbine sizing.

Okay, this is a bit late, but search ebay for "Powerstroke Exhaust Back Pressure Sensor" or "Powerstroke EBP".  

They have approximately a 3.5 bar range, from 34kPa at 0 Volts to 390kPa at 5 Volts.

 

I'm currently using one for both instrumenting my Turbine Inlet Pressure, and another as my MAP sensor.  Works great as a MAP since I don't pull much vacuum at idle anyway, and it gives me roughly the same boost capacity with better resolution than a 4bar sensor!

A long and skiny tube to a standard map sensor works as long as you don't have a leak near the sensor.

 

 

You do have to pick where you are porting the sensor carefully so you don't get problems with venturi effect causing low readings.

 

 

If you want to go all out, get a DLP solutions I08 and datalog 8 channels in nistune.

I used a piece of brake line tubing for this same purpose with my EBP.  I believe they do something similar in production.
