Hey - I resemble that remark ! I actually conceded that even my new stock rod pusscat runs at 620.59 ft lbs:smilie: DKs longitudinal G show a large amount of torque which would bend rods if it did that 100 mile autobahn stint I showed on the graph on the front page - His car will never do that and hopefully will be fine.... BTW - who on here has bent rods ? I have, RS Tuning engine dyno 757NM (557ft lbs) on my 993tt, with a steep torque curve, ran fine for ~10K miles, when it was cracked open for some other work it was "bannana city" and Carrillo time :lol: |

My sympathy for your ordeal, but one car out of hundreds modified does not constitute as data...it is just anecdotal. It is up to individuals to decide about the rods issue, DK and Switzer talk about their experience and I give a slightly different view through 21 years of being immersed in Porsche tuning..... I think we have got somewhere and I have accepted that saying 850NM as a limit cannot be definitive due to dyno numbers and usage.... |

Thanks for that.......you think my "data" comes just from my own car ? I didn't realise my credibilty with you was so shallow ? |
I've got 10,000 miles of 600+ hp under my belt with no problems and I drive my car enthusiastically to say the least. Infact the current turbos are being replaced and will bump my power to around 750bhp. All stock internals with no fear of damage. It's all about the Tuner. |

imo, the main difference is ; in Europe, people always can do top speeds in autobahns. and whenever we roll, the race starts at 50 km/h and doesn't end before 300 km/h. American's usually run 60-130 mph runs and that's it. Yes..that is why we are running all our Switzer car here to TOP END at least twice a week over a summer...did over 13 k miles on SPI 750 without anyprobs and car is making over 830NM for sure... We beat many EURO tuners...you know ??? they still cant catch up... :yup: |

The only Euro tuner into "explodamotors" seems to have that area covered. I think you can claim the most powerful in the world "without internals", time bomb spec :yup: http://i279.photobucket.com/albums/k...3tt/9ff950.jpg BEST 1/4 time on thier 70k EURO 800 HP 997 TT with built enine was high 10s or low 11s...then borke down...nothing but problems... Other EURO tuned 997 TT with GT2 TURBOs with TIPs also lost and engine last week... Futhermore we beat 9FF thier GT2 705HP amd 925 NM with our SPI 750 bolt on kit many times...roling start...there are vids to prove that.... Here is the real world ROAD RACE TESTs...all the time plus we drive the everyday... Over 13k miles with mod on Porsche...racing 2-3 times a week at least, going to tracks and so on...so far soo goood:respekt: 0-100 in 2.8 0-200 in 8.7, 0-300 I think will be very high 19 or low 20... We beat all EURO tuned 997 TT here....Here you can be see best result btw SPI 750 and 9FF 705 an d925 NM GT2 and EDO Competition 650 997 TT http://www.youtube.com/user/TTRprodu...18/3fk1HwR8rJw Note our car has extra passenger...and note the diff.....and the guy who races orange 997 TT is one of the best dirvers, hasd many fast cars inlcuding 8 sec Evo, Utima and so on... http://www.youtube.com/user/TTRprodu...27/6xG-1tK1WnA NO WORDs, NO NUMBERs...NO BS....you can see everything with your eyes...look at the our vid there as well...and you can see what happens... NOW GT2 guy that was beated is getting 1000 HP upgrade by 9FF....and another 997 TT TipS is getting 950 HP kit.... Both will be ready before SPRING next YEAR and I will RUN with them with my new project cr... that is getting built NOW... More to come stay TUNED !!! |
sounds like reputable european tuners such as 9ff are losing their engines even with internals. there is no guarantee that your engine will last any longer with internals. GT Rus has a car now with over 13K miles of hard miles on it. eventually, all motors will fail, but people talk like you will be lucky to make it over a weekend on a road course. let's give credit when credit is due. |

I believe the tuner plays a huge role when it comes to reliability. On a side note, I just stumbled on this movie where the GTR P800 was getting work done on the side of the street. What went wrong? YouTube - Nissan GT-R Switzer P800 remont 2 |
One off the hoses came off...nothing major....After we over boosted the car....It was tuned and tested at lower boost that we set and runned the car that night...so this had to be fixed on street...nothing major... LAST weekends this exact GTR P800 has shown FASTEST 1 mile of 26.9 and 10.418 in 1/4 !!! Owner is super happy !!! http://www.youtube.com/watch?v=tc1x6...layer_embedded |
Well Mike I guess you could say that the "proof is in the pudding" so to speak, and you definitely speak it! :thumbsup: TB993TT, do you know of any differences in the rods between the 993 gt2 and the 997 gt2? |

I do know that the Cargraphic/RS Tuning 997tt which was the fastest Porsche in the latest Sport Auto 0-300kph shootout doing a pretty fast 23.8s used to have 624PS/826NM and was modified pre this test with new Carrillos and re-tuned on the engine dyno to 630PS/900NM - they don't do this for fun, they do it because when the cars are really loaded the rods fail and they don't like failures ! http://i279.photobucket.com/albums/k...0-300again.jpg |

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 !) http://i279.photobucket.com/albums/k...93tt/rods1.jpg 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 ))) |

Are there any of these kits in Germany ? Never heard of any ? 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... Here is the link again: YouTube - TTRproduction's Channel |

Here is the link again: YouTube - TTRproduction's Channel YouTube - TTRproduction's Channel I remember you linked this before..... this doesn't really show a lot, the GT2 pulls away at ~9s then he has to go right onto the other lane/hard shoulder to avoid other traffic at ~14s then he rejoins next to the tt, having to change lanes makes a massive difference to a "race" like this (I know you must know this since you are obviously quite adept at these "races" ;) Are there any others with this 9ff GT2 in them, it looks pretty fast ? |
Dont forget that GT2 is 150kg ligher, manual and 2wd...over 50k in engine mods... If look furher you will find other vids with Evotech 680 HP 997 TT, Enzo, Ford GT1000 and so on, CCX 850 HP... 9FF from a dig (with brake start) and so on...also there is video vs EDO competiton 650 HP 997 TT in 1 mile...and many more... |

No GPS number but best we did on race logic so far 0-100 in 2.8 and 0-200 in 8.7 and we cant hook up properly from tthe start... My car based on which this kit was developed last year...after it was sold to another guy in States...on race logic showed 0-60 in 2.4, 0-100 in 5.9 and 60-130 6.55 Al those number has been verified here and on 6speed... So the reslt we have are not the BEST ones yet...need stickier tyres... 0-300 probably recorded in the BOX but we cant be bothered to download them, similar kit in States runned 0-300 in 21-22 secs...our should be faster... NO doubt its the fastest VTG package out there...and it getting even faster ))) cause Tym never STOP making it better !!! |
The SPI750 has done 191.98(311) in the mile and has a best of 26.959sec for the mile as well. Can't wait to see what it will to with stickier tires on it.. I can't believe you can spin those Michelin PS Cups with it Mike, that is outrageous! What do you think about the R888's? I have heard that they are stickier that the Cups? |
R888 is a stickier tire than Michelin Cups. I've had both of them on my 996tt. |
David, you may want to get a pair of these on the GT2: http://www.tirerack.com/images/tires...o_a6_ci2_l.jpg Hoosier a6 DOT radials, have a UTQG rating of 40-C-A, very sticky :) Wouldn't be a bad tire for the SPI750 tip either, then you could really launch it :D |

Yes...when its getting colder they hook up worst the regualer tyres I think.. I posted pics before here where you could see smoke at the launch and car goes sideways... We wanted to get 888s but they not availlible here till next season... I will have to ask you to get one for us and ship here:lol: with my kits |
Yeah definitely too cool for proper traction that's for sure. Did you get to do anything to warm up the tires before the runs at the unlim? Need to do the road race slalom warm up :) |
No...no time and space to warm up... Went to another drag event 1200 miles away....at 90F car runned 10.525 ad 130+... |
