1990-964

John,

I am also interested in your kit. Will you still honor the intro pricing after you re-open? If not how do I get in on one?

Thanks,

Darren

Darren, Please email me directly we can discuss.

In all honesty, I did not expect such a positive response, thank you everyone. At the moment I have a list of people interested in the kit, however I do not have enough kits to supply everyone who expressed interest. By Monday, I will have a clear idea of how things stand. Individuals who paid for the kit, will get it. People that are on the list, if they have not paid will lose their spot to the next in line.

I will do my best to get a kit to each one interested. I would like to stagger the orders so I can give each one plenty of support if needed.

Make sure you contact me as soon as possible to make arrangements, and please be patient I only have 24-hrs a day!

Looks like you are on a winner here John. How about extending that price break for the first 20 or so?

I sent you an e-mail

Be interested in others experiences as they get their kits.

My mistake, checked four cars currently in the workshop without thinking that they were all 964RS's. D'oh.

A brief update -
- I have replied to every email I received, if I missed one, please email me back.
- Individuals who already paid, I will ship ASAP and you will receive a tracking #.

As of this morning, all of the kits in stock are spoken for, awaiting payments. However, there is good news.

I decided to honor the promotional price for 15 additional kits, to be shipped as soon as I have the products ready. Hopefully before the Holidays, otherwise it will be early January.
If you wish to receive one of the 15 kits, please send me an email so I can add you to my waiting list. You will be notified, in order, as soon as the products are ready ship, payment can be made then. The list will be closed by Monday.

I hope everyone find this agreeable. I apologize for not being able to deliver as many kits as requested by Monday. Your response exceeded my expectations, and I do appreciate it. I look forward to working with the 964 community, hopefully I'll be able to bring you additional performance products and services.


Thanks,
John

Hi, Guys I have been out of town and very busy with work so I missed some of the questions.

But , I don't work for John
I do think my HP gain are a combo of the MAF, and the rest of the parts that I have bolted on.

If there are any other questions, or if you would like to see for your self and in the area just let me know, It is a good reason to get the car out.

258 HP measured at the wheels is pretty impressive. Stock HP is 247, but that is measured at the flywheel. If the drivetrain loss is 15 HP, the approximate gain over stock is 26 HP - more than 10% increase.

John is correct that it is the area under the curve, that matters. Also, sags in the torque response are a problem with many engine mods - more peak HP, but such problems at some speeds that it is not worth it.

I have a bolt stock 964 except for a primary bypass. It is freshly-tuned and running great. Anyone see a problem with lining up side-by-side in 3 rd gear at 2000 RPM and see how much more quickly he reaches 6000 RPM? If he walks away from me, I want to buy the MAF!

Springer,
I am up for it, I sent you my number give me a call, I will be making a run for a little bit this Thursday or Friday afternoon with a friend in the neighborhood. if you or anyone wants to join please do.


As far as the calculation for the drive train loss , it is not 15 hp or 15%
It is the Hp reading from the dyno (258) / .85 = hp at the engine (very close) 303 hp

This method is used by the dyno shops and must tuners

This thread reveals a marketing ploy which converts the typical average
performance chip "sell" of $300-$500 to high profit performance chip
"package" sell which can be three to four times that amount. Since the
performance package buyer doesn't really know what the main so-called
hyped performance benefit is really attributable to, i.e. the chip and/or
the MAF, the seller can "push" other so-called performance items
which by themselves yield no performance gains, i.e. perceived
gains.

This type of sell is easiest with many naive buyers who get sucked in
by the hype and fail to fully analyze and evaluate the hyperbole posted.
As with most/all MAF conversions, little to no performance gains result.
The key to selling that conversion is to "push" the timing maps with the
performance chip supplied to values of 3-5 degrees advance over the
stock chip. Advancing the timing in a performance chip develops basically
all the perceived performance increase, as tweaking the fuel maps for
a NA stock engine yields little over what the OEM originally setup.
Furthermore, the seller never supplies the data of real benefit of the MAF
conversion by itself.

So, like all hyped performance products, BUYER BEWARE!

Strong words Lorennfb. First since the 964 stock dose not support MAF unit you have no choice to use new software. The two work together, they will not work on there separately. Second switching from the AMF of the stock 964 to an aftermarket MAF can give real increases in performance. Since I don't have a dino I have always followed improvement in performance. For me 1/4 mile trap speed has been the contestant and reproducible( less driver dependent ). I obtained a increase of about 4 mph(97 to 101 mph) in the 1/4 mile with the Autothority MAF. This worked out to about a 25 rwhp(30hp crank) increase. Finally, Vitisse Racing has a long history in the 944 community, and enjoys a great reputation, so I give the benefit. Lets be honest the mods done on deoxford's 964 prior to the Vitisse MAF will get you no where near 258 rwhp as shown on his dino run.

Loren,
Hi, I have to stand up for the product I purchased because, I was just as scared of the results if it is not done correctly.
I have to tell you , I did 27 or so pulls on the dyno with John making sure the map was correct and would not be harmful to the engine. I just spent over 7k on a top end rebuild and I want it to last.
We drove around for several hours at normal speeds with his lap top connected to make sure that the engine preformed at all ranges. And It did.
I can tell you with my set up I did see the 258hp number. I can also you that we saw higher numbers then that , but they were not at a safe air fuel ratio. And I know that the timing Maps were not pushed, as they were with the chip I had in the car before.

bumps you up (or is it down now in the new lettering scheme) 2 classes in PCA club racing though. but could be good for NASA GTS.

demonfish

hmm, mine says 98....

donoman

I'm actually curious how much HP was gotten from the software and how much was gotten from the MAF. Then I also wonder "How can an MAF give you that much more HP?" Is it less restrictive? I know if responds faster to changes in airflow but doesn't this just translate into better throttle response (how does it end up giving you FIFTY more ponies WOW!!!

Waiting for before & after dyno's. Then you will have my money!

This took far longer than I expected..........
