I didn't think about pics when I dropped it off at the shop. I can get some tomorrow.

Cool

Forgive this post if I've missed a dyno sheet somewhere in the bowels of this thread, but does anyone have one they could toss on here? Much appreciated! Especially awesome if it has before/after graph...

It will look just like mine. It does fit perfect!

There were some but I think photobuckets lameness has made them all unviewable. I will have to get some up here soon.

The Google Chrome Photobucket plug-in is wonderful!

I have another dyno day on December 9th to try again on the correct tune revision.

Thanks much for the link to your build page! Very helpful to compare against Seb's dyno on one of his blogs. You're touching 300tq at about 4.6k, while Seb's graph hits 300tq at 5.5k. Even though he puts out higher peak hp, your car has a better curve.

It would be interesting to compare the differences between the curves with an A2A setup that's putting out torque numbers in the 425 range or so.

When mine was making only 485whp I had 300wtq By 3.5k. It's the red line. Blue is a buddies 370 with a turbo.

Not to change the current topic but I just read two more small pros for Air-to-Air over Water-to-Air.

- A2A system has less weight
- If the intercooler fails for whatever reason and leaks into engine...bye bye engine.

Albeit, these are small compared to the main reasons...
- Reliability and safety for the engine when frequently using boost.
- Reduces heat soak issues
- Improves performance
- Reduced system complexity
- Reduction of under hood components

Only pro for W2A that I see is for people only doing drag strip runs and they can have a cold car at the line and option to use ice.

Impressive! Thanks for posting it, Topz!

The top is all true statements. But ....I think you meant W2A in this last sentence in bold. Might want to edit that. :hello:

Oh sheet yes my mistake...i will edit. Tx!!!

Supercharger install is complete. Hopefully going to Seb early next week. Thanks goes out to Topgunz, Tbatt, CJM and Lspec (who did the install).

Here is a shot of mine, did the SC install and the A2A install myself, quite the project!

Got my man Jon @ Z1 helping me with a remote tune until my appointment their on the 18th!

Looking good guys. Post up those dyno sheets. Don't forget to tell the tuner to hook up the boost source to the dyno.

Boost source?

So you can get it on your graph, to see your boost curve.,

On a scale of 1 - 10 how difficult of a project was this to install? (10 being the most difficult) also how long did it take you? Thanks much!

I would say the install length depends on how mechanically inclined and organized you are. The install would have taken me alone probably 4 solid days. I am mechanically inclined, I made a binder with all of the install instructions that I could check off as I did them and I only drank moderately lol. With that said, some issues with the SC and my fuel system had the car down for a grand total of a month, I believe. I would probably give it a 5 on the difficulty scale.

EDIT: I also installed the CJM S1-SE fuel return system, billet tophat, AEM? Fuel pump relay/upgraded wiring, and the AMS lightweight crank pulley.

From the start, SC install took me 3 days of 5-6 hours a day. And the Air to air took me 2 days of 2-3 hours a day

Even though I didn't do my install I did monitor the progress daily. Wouldn't you say the fuel system was the most complex part?

I suppose, I didn't really think anything was to complex

Anyone dealt with 928 lately? My SC arrived there for a rebuild on the2nd and I haven't heard a single thing from them acknowledging anything other than my receipt for paying for rebuild and i heard turnaround time was very short with them. I called and emailed them multiple times before ordering/sending off but was never able to get a hold of anybody but went ahead because i heard good things. Pretty nervous for now i'd hold off on using them until further notice

Yes. Just because of the cutting required, making sure that gasket stays fuel-free and the wiring of the pump up to the new tophat.

Please keep us updated on this issue.

I double-checked your build thread, and didn't find a detail on the fuel system and wiring install. Is this complicated enough that a step-by-step description would be helpful for others who are planning the upgrade...similar to what TBatt did for the tophat?

It's not complicated, just difficult to get the hoses routed through all the right places as far as the system installation goes. The fuel system mods took about half of my install time. The directions provided with the system are really good, so I didn't feel that my own walkthrough was necessary, it's just meticulous.

The only tips I would have only reinforce common sense like ensuring everything is tight and doesn't leak! When it comes to the wiring, the wires are somewhat easy to pinch and you have to ensure that they are secure in the connectors.

As you guys may not know i have started on my Air to Air build with Soho motorosports. Pretty much trying to mimic what Evan did with out a built motor. E85 with 928 Super Vortech Upgrade. Will keep everyone posted with the final numbers and how it all went.

What day is the dyno scheduled for?

Give us all the info on your build. SOHO is where I'll be with mine once the new SC kit comes out and I get it self installed.

There are suppose to startc dyno tuning and road testing on the 17th... And I will pick it up on the 25th Black Friday

Will do... Soho is as intrested as everyone is too as well. They are all in on this build.

What pulleys are you going to run?

I was just looking at this video again and noticed that the bpv is mounted vertically. I read some older threads on here saying it could be mounted either vertical or horizontal. Tial says it's designed to be mounted horizontal. Any input?

I have the 9lb stillen pulley and the 2.8 supercharger pulley with a bunch of bigger idler pulleys and Tbats system to avoid any slippage. With the 928 Super Vortech upgrade I plan to spin it much faster so I’m hoping for some really good flow. I will create a diagram of my pulley system after testing to show my final configuration. But we have allot of pulleys to test with and I will report back the best combination and configuration for this setup. I really hope to make about 17psi but i dont know it will be that high since my engine flows real nicely with a lower ported intake manifold and full Motordyne LongTube headers and cat back exhaust. I have no cats on my exhaust system. It will come down to the whole argument of flow vs PSI so all I can do at this point is test and hope for the best.

I'm really curious to see what you get with the different combination of pulleys. Isn't Evan around 700hp? I've got the 9 lb and the 2.87, I'm hoping to get to mid 500's without using them. I've got the Si sc, a2a, tbatt kit and e85 (flex fuel).

Should I run straight pipes with this kit (short tails and test pipes) like I currently am, or should I throw on another aftermarket axleback to create some back pressure?

I just ran across this article yesterday. It should be a sticky. You don't want back pressure, and what you have should be good if you're ok with the sound. From my research, FI and cats just don't work very well. Unless, you have BIG cats, or maybe break them in correctly, or maybe the Fast Intentions Mil Spec cats? In general though, I think most recommend no cats with any form of FI.

This explains back pressure v/s scavenging and why some incorrectly assume back pressure = more HP.
