As usual, absolute jewelry!

jeff spahn

We are getting somewhere.

Chris Lockhart

Any updates Hans?

Dave how's your setup coming along?

Brian, did you figure out your snorkel intake setup for the Keel system?

Before the ice and snow covered us here, man its been cold, I've see -6
Andrew and I did some Shark Tuning with second gear uphill pulls in an industrial park on a sunny Saturday, temps were in the mid to high 50's IIRC.
We did these after letting Auto tune getting the Base map set to 14.7, no WOT just cruse'n around.
We ended up seeing 9psi of boost when we did the WOT and she really really pulled strong after logging and then doing cell adjustments. I ended up burning a LH chip and its installed.

Now the bad, well not really bad just more $
We found I'm running lean 15 and greater over 5,800 RPM under WOT, even after we adjusted the WOT MAP and maxed the cells for that RPM range
I need more FP (have stock S3 installed) so an S4 FPR and 36 lb injectors are the next purchase, then in email conversations w/ John Speaks, Louie Ott and Ed maybe a SMAF too.

The car is a blast to drive, but it will all be coming apart soon, as the inter-cooler leaks and needs to be repaired, and that is when I'll do the new parts, MAF is easy to replace as its accessible.

On another subject I was wonder how hard it would be to install a AC driven chiller in a coolant tank for the inter-cooler using the now disconnected rear AC?
I see the new Doge Demon is using that to get the intake charge temp down for extra HP over the Hellcat

Latest pic, I added the bowden cable to the s4 throttle linkage, but haven't tested it out.

Thanks for asking Chris,

Excellent. Glad you're moving forward, even though you have to take it apart. Your install looks so clean. I'm impressed. I went ahead and got Louie to do the SuperMAF upgrade on mine, and installed 42 lb injectors, so hopefully all will be well when it's time to Shark Tune. :-)

Thanks Chris!
42#ers.., that is what Andrew was suggesting I do too, although the ST MK1 doesn't support them, it only goes up to 36#, so for Idle and all, it will require even more "custom" settings and tuning

However just looking at Ebay from another thread, correct 42#ers seem readily available, I'd also like to do all plastic (no seam) and less heat transfer they say.
It's funny, how you don't really need to go above 5,500 RPM and you still get a BIG grin

John Speake

A 42# option is available, I remember that John Kuhn used it on a turbo car. We were concerned that idle would be perfect under all conditions, but as far as I know
it turned out OK.

Did you data log injector duty cycle when you did your WOT runs ? That would quickly highlight if your injectors are too small.

Chris Lockhart

I was thinking that Andrew has 42# injectors in his GT, IIRC.

Tony

When starting, if it does not "fire" right away, it WILL flood. That is the only draw back i have seen with 42#. I have a switch that disables my fuel pump for such occasions to "lean out" the mixture as i continue to crank.. Just like starting a flooded reciprocating airplane engine. Once it catches i turn the pump on again and away she goes.

Chris Lockhart

Makes sense. Thanks Tony! Hope you are well my friend.

davek9

Yes Andrew is running 42# on his GT and w/o any Issues from what I've seen, (his is an S4, mine is an S3), not sure Tony if AO has/had any starting issues.

John, is that the MK2?
The MK1 Shark Tuner I'm using does not have a 42# option and text below is from the manual:

"Select the “Parameters” tab, and check that the parameters selected agree with the configuration of
your car, especially if it has already been modified from standard. e.g. larger size injectors. Note
that injectors larger than 36# are not supported in LH2.2."

So I'd need to select "Custom", and that will then require a bit more cell adjustment than a standard selection from what I've learned.
We logged, MAF absolute, RPM, AFR, Injector duty cycle, temp, and TPS,
I'll need to load up some logs files and see if I can post some screen shots, however the numbers were all going up (including the AFR# ), nothing was flat line,
A good indication of not enough Fuel coming out even though they were opening up.

Thank you all for the support

Dave

jeff spahn

Hans? Progress?

BrianG

I'm running DEKA 60# injectors in the early Andy Keel manifold, with John's SMAF, as tuned by Collin with the ST2. No starting issues, hot or cold.

Chris Lockhart

Brian, do those later style injectors fit down in the Pizza injector bushings, as it appears in your pic? Just wondering for the future.

Happy New Years fellow Boostards!

Sorry guys. I saw the thread bump, but was a bit under the weather over the weekend.

There is progress on this end, but nothing pretty to show. Have the pulley mounted, and measured the offsets for the tensioner brackets and the power steering pulley spacer to get those parts machined. The tensioner bracket was modified slightly for a 63mm idler instead of the 50mm. I really liked the aesthetic of the 50mm, and even though the bearings were double-row and rated for the speed, I just liked the safety margin of the 63mm. I had to offset it about 8mm lower (towards the crank) and over towards the passenger side. It will now be slighly visible (it was hidden before), but its an all black billet idler, so it will disappear into the system. I doubt anyone else would have ever noticed the change except for me. It ended up being just shy of the 50th revision of the tensioner bracket. If anyone really cares, I can post the models up later in the week.

Its really cold out in the unheated garage, so I have been working mostly on the engine management stuff and also trying to shave cost out of the throttle inlets, and getting the drive extension and pulley manufacturing data over to sweeden for approval and quotation.

I will post some pictures when I get some pretty parts back. Next parts back will either be tensioner or oil filler bits.
