TB993TT, do you know of any differences in the rods between the 993 gt2 and the 997 gt2?

I guess you don't know the history of "internals" AKA rods ? It was when the 993GT2 race cars started hitting 800NM that rod failures were becoming a problem, The GT2 had a "reinforced" version of the standard 993tt rod (see below) but that still bent (my early model '96 993tt had the GT2 rods and bent them !)

The solution came from Carrillo whose fantastic product completely cured this problem and has been used successfully ever since by racers.



The problem with vendors on forums is that punters never get to hear of problems like (poor running on normal fuel - I know in one UK mag a guy rode shotgun in a 800hpGTR and said it felt the same as his stock one - fuel was blamed....!!), only competitors failures (like the 9ff breakdowns - and why is the guy going back to them for 1000hp when his existing one broke ?). Having said that if the above is true and everything is running sweetly for sure credit where credit is due....

i understand from an engineering standpoint that all rods have specific properties and have their limits based up what materials they are made of. i am also aware that when rods failure occurs, it is not always due to exceeding the physical limits of the material properties of the rods. many times rods fail due to improper tuning which causes detonation. SPI has many cars on the street already exceeding the power levels that people are claiming are impossible due to the limits of the rods. obviously this is not true, otherwise SPI would have customers with rod failure all over the world. To date, SPI has not had one customer with rod failure or blown motor. this is not to say that it will never happen. all motors eventually wear and eventually something will fail (maybe not ncessarily a rod). but i simply disagree with people saying that we SPI has exceeded the limits of the stock rods and it is a ticking time bomb.

There is limit to everything at certain stage but there are many 996/997 TT in US runing at over 700WHP on stock components... build motors also faiil )))

We don't have any in the UK, just the one car from EVOMS, the one with the Martini stripes EVO700 with 730hp/750ftlbs on the Mustang and performs like a 550PS car....
Are there any of these kits in Germany ? Never heard of any ?

We have all the German tuners cars here, you name it we raced all of them....Teachart, Evotech, 9FF, Edo Competition, Cargraphic and even Rinspeed and we beat all of them and there are proofs with videos !!!

I sent you like fo our video channel and race with 997 GT2 705 and 925NM by 9FF..build in Germany...some internal done as well...
