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 …

87 S with 2004 GTO LS1

Post  87-944S on Tue Feb 08, 2011 5:34 pm

I've been back at work on the beast and thought it was time to post some progress. I finished the exhaust this past weekend and have been playing around with a 2008-10 Vette intake, and finishing up plumbing the fuel system. Won't be long before I can take it for a first drive. Here's some pics of progress, the cuts for the intake are still rough, will fix all that up. Valve cover is off to be painted, like I did for the driver's side, my gallery has more pics.

Finished Intake

Post  87-944S on Mon Sep 05, 2011 4:40 pm

OK, scrapped the Vette intake, here's the final product, I'm using the 100MM MAF/IAT of the later LS series, IAT is working correctly, the MAF tables need to be modified for the 4 inch intake and 100MM MAF.

The pinched tube on the left will be corrected! I have a lot to learn about HPTuners and making this combo work. I like the compact size of the 100MM MAF/IAT.

do you have a picture/dimensions of that maf tube? I'm wanting to change my intake to the setup you're running, but i'm doing a speed density setup, so no maf. Also where did you get the filter?

Thanks for the compliments! The intake tube is a 22 degree Spectre polished 4 inch tube, the MAF adapter is a GM part # 9166574 available form Summit or your local GM dealer. The air filter is a SLP Performance Blackwing for a Corvette, painfully expensive. I used a dremel to make the opening in the tube and used JB weld to hold the MAF adapter in. Paint is Duplicolor Metal cast, the tube between the BlackWing and the 22 degree tube is Spectre flexible duct, pricey, but did the trick. The BlackWing fits under the nose panel no problem, I welded a little bracket to keep it in place. I have a 924 Turbo nose panel to allow cold air in.

Yeah, one of those what the heck moments! (Unfortunately a few too many of those with this project Rolling Eyes ) It is really well made, and has lots of surface area and fits under the nose panel. All part of the plan to move more air through this engine in the future. Twisted Evil

ya i have a 90 degree elbow right now for a makeshift intake eric threw together. It works fine but I want to get something that pulls from the front like yours. The cost is shitty, but you gotta pay to play sometimes.

I suspect there are other options for the air filter, I bought this one a few years ago, like I said impulse. I bet you can find something equivalent for less money, but it fills the space well! I held on to it too long to send back. I have a few K&N filters that fit, if you bring the intake tube in from the side and do a 90 degree bend.

I've been playing around with this MAF and have learned a lot about VE tuning and MAF tables. It appears that a 3.5 inch tube would be a better solution for a N/A engine. I also have learned a lot about air flow, and that a honey comb air diffuser in front of the 100mm MAF may be needed with the big 4 inch tube to straighten air flow and improve response, right now it runs like crap!

So, for now, I'll pop the original MAF back in with a 3.5 inch tube and 3.5 inch 22 degree elbow until I get some time to play with tuning. I don't need this to slow me down!

why not just do a speed density tune? It may take a bit more learning of hptuners on your end, but it will save alot of time calibrating the MAF.

Thanks, I will look into speed denisity tuning, not familiar with it at all. I'm very new to HPTuners, what I want to do is just get it out of the garage and on the road, then I can play will all this stuff. It is unreal the control you have over everything with HPTuners, and how easy you can screw it up!

speed density uses the MAP sensor instead of the MAF. This way you can completely eliminate the MAF, I'm sure there's a good bit of reading about it on the hptuner boards.

Myself and Eclou both run speed density tunes on our track cars.

Ok, well, here is the interim solution until I learn enough about tuning this engine. This is a few 4 inch to 3.5 inch silicone adapters, and the original 3.5 inch MAF fits nicely to the SLP Blackwing air cleaner. The engine runs well with this setup, but there is always room for improvement!

I drove it today!

Post  87-944S on Sat Sep 17, 2011 8:42 pm

I can't say how great I feel today, the beast has left the garage and did a quick drive down the street. I will post video as soon as I figure out how to edit. I only got to second gear in the S tranny, but all was tight, and no leaks!!! Why did this take so long!

Post  87-944S on Thu Dec 22, 2011 7:32 pm

Xmas came early today, the beginnings of my widebody transformation will start tomorrow. Here are a few pics, much more to come as the build progresses. These are super high quality parts!

Had to go and see these for myself - I am really impressed with the quality of the work.
Definitely look like they're worth the investment (if you don't already have a widebody kit).
Looking forward to seeing the pieces in place!!

Front fender mounted!

Post  87-944S on Tue Dec 27, 2011 9:35 pm

Got a chance to do some work today on the wide body kit, unfortunately it was raining hard and 45 degrees so I couldn't move the car out of the garage to take pictures and do the fenders justice. I'll be documenting each step of the way, and just learned the hard way a long post in progress is not a good thing. Just lost everything I wrote, so this will appear in many shorter posts for my sanity's sake.

The parts should look familiar, I will let the talented designer/manufacturer reveal himself, I can honestly say these are great parts, can't wait to get them installed, but will be taking my time to get things just right.

After removing the front fender, not fun since Porsche glues them in, here is the first test fitting.

[You must be registered and logged in to see this image.]

Mounting holes are clearly marked, and easy to drill, a Unibit works well for this.

[You must be registered and logged in to see this image.]

[You must be registered and logged in to see this image.]

Holes drilled, and test bolt in place, drip rail mimics stock perfectly!

[You must be registered and logged in to see this image.]

Shot of extra material added for fender protection from road debris, mine is a mostly street car so this is much appreciated! The offset hole is my mistake, last time anyone will see this. Detail of mounting surface where front spoiler attaches.

[You must be registered and logged in to see this image.]

Stock fender mounting will need to be duplicated for the three bolts in the inner fender near the door. Material was provided to fabricate this. I hope to do this tomorrow, I will post pictures as I progress. A slightly longer mount needs to be made for where the rear of the fender attaches to the chassis under the car, I will show that as well, it is easy to do, just a small steel strap.

Fender test bolted in place, before wheel spacer added.

A one inch spacer added.

Much better! Note that the vehicle is on jacks, tire angle is perfect when on the ground.

Comparison to stock fender.

Finally, my best friend while working on the front fender. My Fein vibrating tool with the scraper blade made short work of separating the fenders from the glue Porsche used to hold them in. It also made it easy to prep the surface for the new fender.

Many more pictures to come!
