2007 LAPD APS...Numbers and Experiences
Have fun at the OC Block GTG on Sunday, REPRESENT!
Awesome peak numbers though overall for a stock block. Can't say anything bad about the HP curve really. I would really be impressed if that TQ number peaked and then held for about 3000+ RPM over 600RWTQ. That would be cool!!!
Good job LAPD, decent numbers for a stock block.
Need to make similar TQ/HP curves with a large displacement block now!!!
It should be noted the dyno run posted represents a faulty driver-side actuator, it's now since been replaced with the one previously on my car and based on a couple of testrun this evening with Scott at the wheel, I felt boost was holding longer at the rpms...the car felt much stronger than before! I'm sure we'll see better results on the next dyno runs.

Re-post that new graph then. I am curious. I can RE-TRACT, IF I am just like "WOW"!!!!
Have fun in Vegas!!!
Where the "hell' is your dynograph Richard? You ever get those new actuators on your vehicle yet????
I'll post mine up sometime soon. I just built a new Windows Vista based computer and scanner drivers are all "jacked". Maybe this weekend I will find a new software application with some Windows Vista drivers that actually work???

Yes, just had the Forge actuators installed yesterday evening and the car does feel stronger as I left LAPD's parking lot and easily pulled 10psi with just a tap on the GO pedal, I didn't want to hammer it since the tune is not completed and the EBC is setup for the old actuators.
I'll be back Monday evening, hope to get the car on the dyno sometime mid-week.
How's the science project coming along, you need to bring a that baddazz ride to one of the GTGs and makes us...

Alright!!!! Cool.
Let me know how that "puppy" feels!!!
That APS Z06 kit is coming anyway, IF that stock APS kit IS NOT working for you!!! Maybe they can retrofit???
Anyway, that's great news. I'm happy for you. Let me know on that and yeah I'm curious to see your powerband via dynograph!!!
I'll post mine up (dyno) and hit the GTG sometime!!
I bet that Z06 kit might work for us larger displacement guys!!!
I'm running a JT Trim Vortech now on mine, just to be different!!!

The car is a lot more responsive now and comes up on boost a lot faster. The car feels like it is definitely up on power from driving it previously. I have been babying it around since the tune was based on the old boost ramp rate.
More to come!

I am sure your C6 is simply a beast and I am sure this bozo is going to eat his words once you post your final dyno sheet.
This is all "in fun", so no need to "eat" words, and no need to call people "bozos".
No wonder I had to help alot of my buddies at the local PD through their classes in school. LE officers tend to need help in understanding people's opinions, since their's is ALWAYS the correct one it seems??
It's cool, that remark was beyond what was needed. Actual evidence can of course change my opinion!!
C6 XPLOSVE...There is no mention of any "shot" at your profession in this post....so the post below makes about as much sense to me anyway as your very unprofessional opinion as a LEO representing. I stated in my opinion, LEO's tend to think their opinion is more correct than everyone else's. I doubt you will find too many disagreeing with that.

First off, nobody wants to hear your dumb comments after they spent a lot of money on a brand new car like Scott did. Keep that in mind and post with more care.
Second off, you have to be one complete idiot to post negative comments about someone's profession on here. While you are sleeping at night, guys like me are out there keeping the streets safe and you have the audacity to post negative comments about police officers? Remember that the next time you pick up the phone to dial 911 when you need our help! I am sure all the other LEO on the forum here would agree with me.

I took a little time to read back through the thread that you started a couple of months ago on APS vs. A&A and I pulled some numbers off of there (http://forums.corvetteforum.com/show...php?t=1529979). Here are the results of my dyno vs the A&A car that you posted in that thread:
RPM......A&A.................APS........ .......Difference (APS - A&A)
3000.....440tq 250hp...450tq 260hp...+10tq +10hp
4000.....520tq 400hp...580tq 440hp...+60tq +40hp
5000.....555tq 530hp...600tq 570hp...+45tq +40hp
6000.....540tq 600hp...520tq 590hp...-20tq -10hp
6500.....525tq 650hp...465tq 575hp...-60tq -75hp
........................................ ...............___________
........................................ ...............+35tq +5hp
I must have missed it in the 6 pages, but I didn't see if there were boost numbers posted on what the A&A car was running. On the first dyno that was posted the sheet is showing 10psi...what was the final boost number on that car? I am pretty sure that the torque will carry further now that the actuator problem is fixed and I also believe that the hp/tq will come up faster as a result of the WG staying completely shut.
Is the blower car from the first comparison still together? I'm more then willing to put the cars on the same dyno back-to-back at the same boost level. Two cars on the same dyno, same boost, on 91 octane pump gas, and both with meth injection. That would be as apples to apples as you could get.
Richard, C6 XPLOSVE, and everybody else...thanks for the support

Yeah, that was a "nightmare" thread. Had people calling me on the phone "all crazy" about that (not to mention the thread itself). It was supposed to be fun, BUT after a "bit" it got "stupid". I'm not one to let people "talk" too much crap, BUT anyway!!!! I forgot about it.
As for your vehicle, it's pretty impressive! I am curious to see a dyno sheet to check it out. Sounds great!
My vehicle now has changed ALOT!!! So all I can say is who knows how it will be at any one point in time. I'm actually developing about 740 RWTQ / 740 RWHP +/- (forged 402-no meth-street tune) at this point restricting the air input to keep my numbers even and sane. That's about what I wanted anyway on my particular setup. I can't see having a manual car with any higher numbers that's really "driveable" on this Corvette platform.
I was avoiding the turbos myself on my manual transmission application because of "driveability" (...but that's just my take on the manual transmission and turbo power adder at +600 RWTQ/RWHP). I really like the turbo for the automatic transmission, so I am thinking about buying an auto C6 as well and turboing it with the HP turbo kit probably sometime later this year. I like the APS kit, but I feel it has limited expandability, SO naturally people "hate" when they hear this opinion.
If APS can expand their head units in the future, then I would not have any issues with their kit! I would probably buy one for that automatic application?? It certainly is a "clean" install for sure on that kit.
It would have been nice to have seen those two vehicles side by side, but I'm so dynamic lately with the changes on the car, that the "old" post seems like ancient history to me!!! I'm sure you would have "got me" anyway on the "peak power issue" and made everyone "proud" whose at the "crew" down there. Tell them I said, "Hi". No issues or anything on "my end" as I obviously have given them some "biz" as well on another vehicle.
Take it easy for now! Your turbo car(s) will always develop higher peak HP/TQ numbers no doubt, BUT I guess it depends on the driver in a race.
I'm just out to have some fun, and to use this hobby to "kill" the stress from stupid everyday work and the system in general!!
Have fun!! Nice numbers!

The stock LS2 engine has a rev limit of approx 6600 rpm (plus 2400 rpm beyond peak torque) so to hold 600 lbs ft to redline would result in 750 whp which is highly unlikely at low boost pressure through the stock heads and camshaft.
Peter
I was notating that Scott's graph seem to spike over 600 for a sec and then decline. It's cool, that's just the way the turbo compressor is. His HP lines looked sweet on that!!
The issues I have heard time and time again on that kit are not being able to hold the boost pressure. It's like "blowing your wad" before you have fully obtained maximum "squirt" distance potential. LOL!!!
It's cool, it seems to be actuator related, but anyway....
I still maintain your kit is awesome. It just needs additional potential via turbo head unit sizing and perhaps better actuators or replacable actuators for us large displacement boys and for those boys that are "pushing hard" on the stock sized block!!!!
You better hurry up and "fix" those issues or I'll have to start another VS. thread!!!! Heh heh!!! Nah!!! That's too much drama!!! Perhaps, I will try an HP vs. APS debate though later this year, IF you guys still haven't resolved all your issues!!!
Cheers man, I'm just messing around, BUT I couldn't help jacking around a 'lil bit ever since late last year!!!! Fix that stuff up for real man and then no one can talk s&*^ about that kit!!! It's almost there as being "the kit", but like I said "fix" the issues.....AND HURRY UP....JEEEZUS!!! Good luck!!
You can "dog" on me a bit, it's all in fun!!!
