Yeah those are some nice pics of that car. If I may, have you ever dynoed the car and have any results you could share with us? I would love to see what that beautiful car can do, since it has tons of work done to it?

The below copied from 968.net http://65.61.16.109/forum/topic.asp?...91&whichpage=4
Flywheel torque + horsepower
using 13.6% loss = TCF shows 14%
- Left graph shows torque @ 3543 rpm
my HMR 968 turbo makes 131.8 ft/lbs more torque = 65% increase
- Right graph shows power 66.5% increase @ 7.88 psi (very efficient engine)
The boost I am working with is important to the interpretation of these numbers. I am still breaking in the engine so boost is very low.

More stats
Rear wheel torque + power
- True torque to gound
- to get "relative rear wheel torque" YOU MUST divide by Final Drive Ratio 4.197
- DynaPack reads true, generally lower number than Dynojet
Top line w/turbo, bottom line stock before engine conversion

I have kept the interior near factory stock. Whenever possible, I wanted my modifications to have a look that could have come from the "factory." So there is really nothing visually out of the ordinary that one will see in the interior.

I did replace the stock radio head unit with an Alpine

and then of course added some amps in the right rear well under the carpet

and an 8" subwoofer in the LEFT rear well under the carpet

Very, very beautiful. That's why I love to see interior shots on highly modded cars...the interiors are usually like the day they left the factory and in perfect shape. Even after all this time the interior design is still way up there in my book. Everything the driver needs, nothing he doesn't.
Well done indeed.

Grant: You have a gorgeous/stealth looking 968T, wow! And it is in mint condition too! How many miles on that thing? I assume this is a weekend only car too? How long did it take to do the build? Do you have a spec sheet or a web site on the car? I went and clicked on your profile, which listed a web site, but it came up blank. How many of these cars has HMR built, do you know? Any idea of what projected RWHP & TQ you can make on modest boost and pump gas?
Cheers, for it's a beautiful car!

My 968 has not and will not be a garage queen. I purchased it from Brumos in Jacksonville in 1994. I traded in my 1985.5 944 which I had purchased new and had put 125,000 miles on the odometer. By 2003 my 968 had about 100K miles. Always garaged and correctly maintained.
I met Jason Lee while he was a graduate student at UF. We kept in touch after he left for Tampa to start HMR. I visited HMR, and was very impressed by what they had accomplished, and by their vision of where they (Jason and Jason) were going to take HMR. In 2003 with 100k miles, I was thinking sell the 968, or renovate / restore. After assessing my wants and needs, and checking out the market for alternatives, I decided to keep the 968 and asked HMR to bring my 968 up to the best of contemporary standards. In December 2003 I handed over my 968 to HMR.
HMR designed and fabricated many new and improved parts for my 968, some of which they have brought to market. The highly regarded HMR radiator is one example. Another example is the HMR exhaust (see photo below). My 968 has a lot of new HMR technology and design.
![](http://www.members.***.net/968/photos2006/exhau1.jpg)
Because my 968 turbo conversion was #1 for HMR, it was 2.5 years to complete all the work. Good design takes time, and the work was done right. Shortly after my build was completed, HMR completed another, and will soon deliver a third (a red 968 turbo). I believe engine work is underway on an additional three 968 turbos. With design and fabrication of many of their unique parts completed, throughput will naturally increase.
I will let you know more about HP gains when the engine has some more miles.

Anyway, that exhaust they offer, is that a full 4 inch system, or is it a "graduated" one, that goes from 3, to 3.5, to 4? Have you monitored or tested any variables by themselves? Notice any temps drops with that rad? Which exact model is that, the .475 one? You didn't mention having a web site as I said, nor a spec sheet too. Do you for the build-out? That said, some quick questions if you don't mind sharing. Did you have any lightened internals? What is your CR? Headwork? When its broken in, what is the range or PSI you plan to run either on pump or race?

Jason has the most well equipped machine shop I have seen. Among his myriad of machines is an exhaust flow meter. So exhaust can be fabricated and checked for optimum back pressure and flow on the bench, and calibrated on the engine with dynapack attached.
This exhaust is custom made to match my engine set up, and my performance and aesthetic objectives. For more, you will need to contact Heritage.

Jason met the challenge, designed a new radiator, and had a friend of his that fabricates F1 race car radiators do the actual build from his mockup.
Since driving the finished turbo conversion, I have not seen anything except flat temps in the right range. I had a before and after photo of the radiator on my web site and posted here or at 968.net I will look around for it and repost.

Thanks for sharing what you did Grant, the car truly is stealth and gorgeous looking. If you ever crank up the boost and hit the dyno again, please let us know.
Best wishes!
