Mine will be here tomorrow but the dyno guys in the area aren't real interested in doing the testing before in after the install despite paying for it. Looks they only want to do big install projects. Will keep looking in the area.
Photo of your install? Want to see what it looks like with intake tube.
Will do after I get a new phone sick of the Android gig! fails to load pictures. Looks great and after like 500 now this mod delivers more power no doubt here.
Do you have data for the improvement from this? My testing indicates air inside the fender cavity is ambient.
If your sitting and/or creeping up in the staging lane with the engine running and the sun's heat radiating back up off the track surface then the temps are not going to be ambient in the fender cavity until the car gets moving; well a front mounted air duct will bring the fender air up to ambient 'quicker' which means more power 'sooner'.
As far as data goes the only thing that I have 'experienced' is an improvement in the first half of the track like a 105 or just make a 106 mph in the 1/8 mile; but not so much in the second half of the 1/4 mile.
Now if it is a cold day than the front air duct will have less of an effect if at all.
Here is a time slip from MIR coming out at an idle doing some launch testing, etc. that day. Note: the 1/8 mile MPH.

Got to see my M7 first time since july! I brought the 95 MM TB along and finally got it on and the test drive is over two words ! Smoother and WOW! When you open it up it is ridiculous! OBIVOUSLY runs stronger! This is with the Halltech/ 2300/ 95 MM tb and 2 inch coated ARH/tuned!
It's a wash. When you go from Zero to Hero on the throttle.

* It seemed that I got more results with less pedal under normal part throttle acceleration. That I expected but it still felt good; as good or better than a ported TB which I have on the shelf along with a stocker.
* Towards the end of the drive when everything is fully warmed up I nailed it a number of times from a 40-65 mph roll mostly in Tour Mode which "I" personally use 99% of the time on the street (Good for rims?) but also made some hits in Sport Mode too.
* In Sport Mode I got a DIC message a number of times after nailing it and letting off which I don't remember seeing before, that read: Competition Shift Active but then again I don't usually drive in Sport Mode.
* Overall my "A$$ DYNO" (It's been fooled before) will not count; this needs to be settle in the real world i.e. 'The Track'. Will report when I find something out.
Side Note: During the drive I pulled up behind a new Camaro with dual twin exhaust (what model is that?) which stepped on it a little ways out from the light which I was ready for; well I closed the gap real quick and hit the brakes.
Track Report:
I have been to the track twice now with the 'bolt on' (with adapter) ZR1 95mm TB , one time was a 1/8 mile day & the other a 1/4 mile Test & Tune evening. Taking everything into consideration; it's a wash. I did have one guy who has a Hell Cat which I have ran before say to me that the car sounds different on the shift (more like a manual) i.e. more of a delay in the shift. So being it's an overall wash on the time slip (mile per hour may of went down) I'm thinking maybe how uniformly the air is being monitored by the stock tune with this throttle body may be having an effect which could be detrimental. So the A8 is going back to the stock throttle body.

The 10-20 hp or if you even have that again which is why the dyno tells us the AFR and you can look at all the elements of the tune. I don't thing the true value of any mod shows till it is on the dyno. I think you need the tune and then the need for it. I'll be seeing results on dyno soon enough. I already have the before numbers.
ZR1 throttle body has now been replaced with the factory original. I think the real test of true performance & power is where the rubber meets the road in the real world!
Example: When I went to the test and tune there was a 'beautiful' wide body custom $450,000 GTR there which according to the owner makes 850 HP at the wheels. Well he just had it re-tuned and put down his best ET to date; can we say 10.0 in the 1/4 mile.
I think a pulley & tune 'could' put mine in the 9 second zone and it would not have that kind of HP at the wheels.

According to him that is what the guy he bought it from put into it (the best of everything). He bought it for $130,000 and put an additional $20,000 into it. I have to say that is the best looking (mean) GTR I have seen.

* First guy bought the car new and put additional money into the car to bring his total investment in the car to $450,000 'according' to the second guy/owner who bought the car from the first guy.
* Second guy/owner of the car paid the first guy $130,000 for the ($450,000) car but then added additional mods amounting to $20,000 which would bring the second guy's total investment in the car to $150,000.

Todays DA was approx. 1100 feet worse than when I ran the 95mm TB down the 1/4 so ET was better for the LT5 TB running at the same track and in the same lane, however the stock TB did put up a slightly better mph (approx.1/2 mph) by the end of the 1/4.
Interesting side note from todays test & tune:
Friend of mine towed his Demon to the track today to make a few passes, he had the 840 HP computer installed with the required 100 octane gas and the skinnies on the front with MT drag radials on the back (not the factory drag radials). He made a pass then we both let our cars cool. I got to the track before he did so I had made a number of passes in a row before he got there so my car was really hot. Well after the cool down we both went up to make a pass. I was right behind him in the staging lane so I went down the track right after him. We compared slips afterward. He had me by 11 hundredths in the 60 foot but only 6 hundredths of a second by the end of the 1/4 mile.
I then threatened him and said that I might have to get a pulley.

Just to confirm, your test and mods were on a stock tune, correct?
If yes, then read the last few posts of mine in the VaraRam thread.
You may want to keep the 95mm TB as there may be a deeper reason for your power losses, and someone I have met is about to manufacture the fix, that no shop or vendor on this forum is apparently even conscious of yet.
