    The Tim or Tim941NYC or Callahan Motorworks

    A+ Service

    A+ Performance

    A++ Price (compared to other NY service/maintenance people)


    I will write a detailed analysis as we go along so this is the 1st part only.


    Callahan Motor Works
    24 Werman Court, Plainview NY 11803
    T 516 586 5550


    Tim Siachitano is the owner of Callahan Motor Works and is world famous for his 162 mph (1/4 mile) 996 Turbo, recent winner of the Texas Mile at 234 mph and generally all round great guy.

    I actually met him in person for just the 1st time today and spent 3 hours with him talking about cars, and engineering and aerodynamics, turbos, cam timing... pretty much everything, even our love of tropical fish of which Tim has a very nice collection indeed. He showed me some of his home made rigs for the Porsche 996 Turbos, his red beast and some of the in house parts he has developed for his racing set up... all very ingenious, well thought out and particularly well designed.

    I am rarely impressed by people, especially in this world of GERMAN car performance people, and REALLY especially in NY. Tim is a very nice man and seems to have a dying passion for Porsche cars.

    How did we get here

    We bought a 2005 Porsche Turbo S 996 with some exisiting mods including an

    EVOMS vflow air box
    AWE GT2 Carbon Fibre Wing
    AWE GT2 race exhaust (200 cell cats) and
    a very old 2006 GIAC tune which was all over the place to say the least

    I drove the car for a few weeks, knew it had issues, sought advice, bought a Durametric cable, did tests which showed DC% WAY over 100% and a weird overboost, overtimed tune.

    I decided to buy a Eurodyne package so I could see in DETAIL maps for the various aspects of the tune. There is a thread here about Eurodyne

    http://www.porscheboost.com/showthre...ware-Purchased

    Anyway, long story short, I took my car to the AWD dyno at a local tuning shop to do a baseline test of my base Eurodyne tune... the car threw a fit and busted the front axle and coupling case (diff).... so off to Tim we went after getting some advice from some nice folks here on bimmerboost

    The project for part 1 included

    1. New coils
    2. New colder level spark plugs
    3. New fueling system with ID1000s, Wallbro intank pump E85 400 HPFP, return lines 6an 8an etc
    4. New Eurodyne tune from Tim (he is a Eurodyne dealer)
    5. Remove front diff and convert to RWD
    6. Source and install coilovers and GT2 alignment suspension

    As well as this Tim fixed 3 other problems I was unaware of (well, one I was kind of aware of but you know Emu head in the sand and all) plus he had the car detailed.

    So he replaced a faulty radiator, repaired an incorrectly bolted clutch/cross member support and repaired an annoying rattle around the sun roof.

    All the above was completed quickly, efficiently and rather perfectly IMHO.

    We have 1 job left which is sourcing some more GT2 parts so that an Ohlins DFV Street/Track suspension kit can be installed - see here http://issuu.com/ohlinsusa/docs/rt_k...570953/4608515

    So I drove the car home just now after taking a scenic route to give it some curry in 2nd, 3rd and 4th gears...

    1. Fuel mpg has gone from low 22 HWY to 29 including my WOT runs
    2. The car pulls better in 1st and 2nd gear and much better in 3rd-6th
    3. The car holds boost steadily and calmly, no crazy overboost
    4. EVEN with Id1000s the car idles very gently at just under 800 rpm

    RWD -Oh giggity, this is some fun, with just the stock suspension as is, the car gets nicely squirrely into bends and holds a scary oversteer which is fun... before with AWD the word I used to describe the car was PLANTED, a big fat ass semi-heavy planted sports car... now the word I use is light, everything feels much lighter despite only really losing about 70-80 lbs all up with all the mods to RWD.. for mind it is more fun to drive now but one has to be a little more vigilant !

    More to come

    The car will get the Ohlins done some time in the near future and we will probably upgrade the clutch which was slipping above 6600 rpm in 3rd gear and then after summer probably use better Rods such as Carillo to upgrade the sometimes dodgy stock components.

    Tim is starting some work on 997's with Mark (Spoolbus) prodigymb and can do whatever mod your Porsche needs through to the latest 991 model/s. My neighbour just got a new 991 Turbo S yesterday so I have referred the old codger to Tim for some MOAR power.

    Glad to hear you are happy with his work.

    Question, 162 mile per hour 996? I'm missing something here.

    yeah amazing engineering, the guy has rigs for all sorts of set ups to do his own machining specs, cam timing, yada yada yada

    The car will go 255 mph apparently at max.

    Apparently with a different aerodynamic set up out back it should go over 240 for 1 mile... the car has what I call a flattening wing but, the lip off the 996TT rear set up affects it's drag, so I think he is looking to get more of a CS4 rear cover which will aid the large wing... should smooth out the air flow

    Taking today for the clutch, then he will get the Ohlins done and after summer I will probably do the rods, later turbos I guess

    Okay, my car is done, full RWD conversion with GT2/GT3 alignment using Ohlins DFV suspension...

    The amount of work Tim does for the price is amazing.

    I will post some pictures and driving reviews next week.

    If you have a Porsche in the tristate area and want perfect work done 1st time go to Tim.

    If you read all the forums you will hear horror story after horror story of many other shops in USA

    Well we know what happened last time don't we Click here to enlarge

    Click here to enlarge

    When it was dynoed and broke the axle, viscous housing, it hit 429 awhp at 50 mph, the effing idiots did this in 3rd gear... so extrapolating from similar mods and dynos it would have been about 470-480 awhp in a proper 4th gear pull at max.

    The times with the new Eurodyne TimNYC941 tune were much quicker in my 3rd gear pulls measured with Eurodyne logging software

    2500-6000rpm AWD 4.362s GIAC

    2500-6150rpm 3.690s
    Eurodyne RWD


    I will drive it for a few weeks on E20 or so and then dyno before any more mods

    Picked up the car with the Ohlins DFV suspension and full RWD conversion

    The word I use for AWD TTS is planted, fat and steady

    The word I use for RWD (GT2) is flighty, fast and oversteering... I love it

    I took the TTS for a quick 80 mile jaunt around some windy roads and a few unmonitored fast straights... the new clutch is GREAT, I put the car in 3rd at 30 mph and floored it and it zoomed to 95 mph way under the redline... I held it there for a few seconds and jammed it into 4th and zoomed to 130 and quickly braked.

    I will do a vbox test when I am 100% certain there are no cops.

    The car is certainly more involving now especially around bends.... I did some nice oversteer drifts in 2nd and 3rd around some unoccupied roads and got a nice slide going

    Giggity

    So Tim even washed my car as I came to pick her up.
