BMS Z06 Drop In Filter here: http://burgertuning.com/corvette_c7_...ke_filter.html
***

Wasn't planning on taking one home but the close out deals were just too cheap to pass up. $90k sticker, $73k sale price. Went with the 8spd automatic as it appears they tend to put down better drag times. Might make an intake or a little tuner for it, but nothing major planned. Expect to see videos of our various development BMW's smacking this Z06 in rolling races soon. ;)

I'll do some VBOX 60-130 and 1/4 mile runs soon just so we can see where it stands. I've seen numbers on the forums with traps ranging anywhere from 120mph to 135mph on a stock car! Haven't been able to race it around too much yet but it feels a little slower than our PURE S2 M3 so far.

I was looking at a black one.

Looks great! If you want one jump on it before the 2016s are gone! :)

A418t81 10-02-2016 08:42 PM

Wow, that's a smoking deal. Look forward to seeing the usual metrics and tweaks you come up with.

Payam @ BMS 10-02-2016 09:23 PM

Congrats Terry! Still got an HP tuners VCM suite lying around somewhere? lol

If they'd give a discount like yours I would seriously consider it. Unfortunately that was a $96.4k car, and $90k is as low as they'll go. Too rich for my blood when I'm looking for a house. :(

Terry @ BMS 10-03-2016 09:20 AM

Strange, part of the deal right now is Chevy has 10% cash back on 2016 models. Then the dealer discounted it another 9% or whatever to arrive at the final price.

Houses are a much better use of money though.:)

Newguy123 10-03-2016 09:27 AM

sweet. i took a stock 7 speed m/t down at an event in AZ. with basic bolt ons and good gas that car will romp on most bmws ;)

Yeah, it was at the end of July. They didn't have this special.

Does not take much to get these in the 9's at 140mph. Less than $2,500 in mods(tune(93), intake, xpipe, pulley).

Terry @ BMS 10-03-2016 12:55 PM

Yes I'll have to dust off my old HPtuners software, lol.

I read a big issue with flashing these was the warranty so thought there might be a small market for a cheap AFR box or something that allows limited tuning without having to flash it. Hopefully enough to justify this thing as a business expense anyway. ;)

FC4 10-03-2016 03:35 PM

Badass, Terry.

Best intake on the market is the Halltech, so take a look at it for some guidelines. The gains it provides are enough for me not to mention for fear of people calling bull****.

It's funny you mention it... Just took apart the intake system today. I noticed AFE and Haltech are the main intake options? They basically look the same to me?

Anyway this factory plastic piece is huge and has a nice taper down to the factory throttle body. Why would they ever replace this piece?

It looks like the engine technology has not progressed much on the LT4. It's still running open loop MAF at full throttle? :character0264:

So many of the intake dynos have the AFR trace missing but the ones that do all show a much leaner AFR with the intake added. They probably claim its because of the higher airflow. But they all resize the MAF housing which would also lean out the AFR. I wonder if the "huge" power gains they pickup are from the leaner AFR and not the extra airflow/boost claimed. If so just dumping in 20% E85 may provide the same power gain.

Like this AFE dyno... Intake flow becomes more restrictive as air demand increases so increasing intake flow should make more of a difference as RPM increases. But they claim a huge gain at low RPM too. And interestingly the AFR is consistently leaner across the board indicating MAF rescaling.

True, but that data is as good as it gets in this crowd. Not a very sophisticated bunch.

Terry @ BMS 10-03-2016 09:49 PM

Looks like it. Really what I want to see is a before/after dyno trace showing AFR and boost as logged via the dyno. To tell if the gain is from more airflow (e.g. higher boost), leaner AFR, or maybe a combination. Searched there for an hour or two reading old threads and found it exhausting. So little good data shared.

Oh well shouldn't be too hard to gather the data I want myself just so I know. I'm really shocked the car doesn't run full time closed loop off widebands. I mean a BMW 320i has that technology.

Mike_L 10-03-2016 11:23 PM

GM doesn't have widebands on anything I don't think. I mean Ford only has them on the EcoBoosts. Domestic manufacturers prefer to keep things cheap and simple.

Newguy123 10-04-2016 07:21 AM

i heard you were road tripping it to nfz AZ in a couple weeks with the Z...... ;p

Terry @ BMS 10-04-2016 07:40 AM

Me? No way lol. No interest in driving out to AZ. Payam is going to race it at Shift Sector though. :)

quattr0 10-04-2016 10:20 AM

Wrong forum, Terry..... ;-) Congrats sir! This should be breaking news..."Top BMW tuner is moving to American muscle car!"

Kidding aside, can't wait to hear more from you.

steeve13m 10-04-2016 11:41 AM

Ya curious why the jump to american muscle?

So we have a handy fast race comparison car. Plus, I like the way it looks in the garage. Worry not we still have something like 12 development BMWs. :)

Terry @ BMS 10-04-2016 09:40 PM

Was able to sneak in a quick VBOX run on straight 91 octane... low 11s @ 130mph, 8.0 60-130 as recorded during the 1/4 mile run. This thing moves.

I'll up the octane later and pop the SD card in for some better numbers when schedule permits. Busy tuning up everyone for no fly zone and shift sector. :)

The C7Z is a monster in stock form...you should be able to get that 60-130 down easily :burnrubber:

ltrain925 10-05-2016 11:37 AM

Terry,

How do you like the A8 compared to the DCT in the BMW, performance and fun factor? Btw GM just released a 100 octane tune flash that keeps factory warranty, gets flashed at dealerships.

135idct 10-05-2016 12:22 PM

just remove the tiny oem supercharger and install F1-X u will hit 1100 rwhp meth+pump gas 93 at 22 psi stock engine can handle it :burnrubber:

Prochargers suck. Like Vortechs, they make numbers but no performance. If you're gonna be supercharged, positive displacement is the only way to go, twin screw is greatly preferred over roots. If you must have centrifugal, go turbo instead. Centrifugal is basically a belt driven turbo anyway, so why waste power spinning it when the exhaust can do it better with less losses?

:burnrubber: sounds like a 9 second car with minimal mods :clap:

Bimmer_Boost 10-05-2016 02:09 PM

I have seen one at the strip and Shift S3ctor. I don't know what all he had done but he was running a full cage, nitrous, and slicks. He was running low 10's in the 140's mph. I don't recall what he ran at Shift S3ctor though.

The DCT is better from a roll.. But the A8 is much better from a launch as you can brake boost it. It's a stronger trans too. If we had the GM A8 in a 135 or 335 we'd probably have 9 second cars already.

That might be possible. GM does sell a control unit for their trannys. So if you can have an adapter plate made and figure out how to get the BMW computer to interface with the GM controller........

Newguy123 10-05-2016 09:45 PM

Terry are they slightly de tuned from the factory for the first 1k miles or so?

I must admit, I really like the new Z06. I think if I was to go American muscle though I would likley go with a Gen 5 Viper.

I bet if you used a Whipple or Kenne Bell or even a turbo, and made the same power, it would be quicker.

No. The fastest supercharged builds are all centrifugal. PD setups don't even come close.
