HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Headers, headers, HEADERS! - Page 4 Empty perfect timing

Post  xschop Wed Jul 01, 2009 9:07 am

This is actually perfect timing because I want to install the driver's side header before making the final design to the dual MC setup. It may have to be tilted towards the passenger's side which would put the top reservoirs perfectly upright......couldn't ask for a better situation....

Headers, headers, HEADERS! - Page 4 Empty Dual MC

Post  xschop Wed Jul 01, 2009 9:20 am

It is a Dual Master Cylinder with a balance bar that we are working on. It gets rid of the vacuum booster from the firewall and also does not require a bunch of potentially hazardous hydraulic lines everywhere like a hydroboost system. I actually rode in a Cobra kit car with a big block installed. It had dual MC's and the braking was unbelievable.....

Updated pics of the Hooker driver side header. I've cut down the vertical leg a bit to make the horizontal length parallel to the flange. The following pics show the clearance around the firewall, steering shaft knuckle and brake MC.

I'm prepping the pieces for welding right now - should have it tacked tomorrow.

So how much longer is the #1 primary vs. 3, 5 and 7?? Or did I miss something?

Hey Gt and Chop: don't drag me into the ring just yet. Remember I'm the guy who likes carbs and simplicity...(I know about the MSD conversion, thx.) Plus I'm still beating the snot out of my 928 daily!
Now what I really want to get into is the Dark Side of the dark side: FORD POWER...
Mat B started this 4.6 itch and nailed it! I want to go old 347 or 408w... That'll be a challenge, keeping the dist in the proper location,low hood line and all.
Never mind my problems- keep that header project going! Very Happy

Yea, 408, normally aspirated will crank 500 ft/lbs all day long. I built Ford SBs before I bought the 944 (about 23 years, I think)...huge heads and a lot of cam, and they will pound out the torque. 347 may be the better choice here...turn more RRRs, high horsepower with decent torque. May save the transaxle...

BTW, anything is possible...we don't listen to things like "You can't fit a carbed BB Chevy under a stock 928 hood"...or, "You can't put a 350 in the back of a 911 without an RH kit", or, "You can't put Toyota / Lexus parts on a Porsche".

"WATCH THIS"...is what I say.

Post  968gene Thu Jul 02, 2009 9:04 pm

I know this might make me look like a complete idiot, but I'll take the chance... Has anyone tried to install a set of shorty headers in reverse? I do realize that this might solve one problem while creating another (exhaust now routed from the front of the engine compartment etc.), but I thought I would ask. I once used two left exhaust manifolds from a Rover 3800 to install a Buick 215 V8 in a 914. Sourcing two lefts was a challenge, but it did work well. Thanks. Gene

Tried a whole bunch of the factory cast exhaust manifolds when I was working through some turbo ideas, as well as a few other tubular headers. Flipped them around, upside down and everything. If the exhaust exits forward, there's a really tight 180 degree bend to get it going backward. Also, you would probably need to re-design the motor mounts, and re-locate the alternator.

It is very tight in there!

Please, no 215 swaps... Rolling Eyes I had the pleasure of working with one in a 911 (well 912 really). talk about swaps that are hard to keep together. (this was in the late 80's). Great idea, poor end result. This poor car was handed down a bunch of times and each fellow tried to make it "better". I still cringe when I see header studs that are 3/8" down to 1/4-20. and crooked heli-coils... sorry to offend the Rover faithful, just my example left me wanting more.

OK all, I've entered a new topic into the "how to" section that describes how to modify the Hooker 2312 driver side header, including all the steps, diagrams and dimensions. If you see anything missing, or need additional photos or dimensions, please let me know.

Very nicely done. That definitely gives people a reasonable option. RH's headers were absurdly overpriced. I paid less for larger primary long tubes on my RX7 LS1.

This is a good solution if you aren't looking to squeeze every pony out. For those that want more, custom mid/long tubes will likely be the best bet.

sweet. that last pipe looks like a doosey, anyone got a cnc bender in their basement?

actually, at a glance, you might be able to make this out of a single J bend!

Hey Johnny, Ive been trying to figure out what J bend to get this morning. what is the radius of the 90 degree bend? Ive been looking for a mild steel 1-5/8", 18 gauge 3" radius J bend, but they seem to only come in 2.5" and 4", maybe I have the radius wrong?

They're all 2" radii bends (distance between pivot point and centreline of tube) - I'll update the diagrams to include this dim.

Here's a place for custom bends, if you're going to source them yourself:
