( excuse my english ) I test yesterday a few time my top end , with Z-tube and stock tube , and I only 136 MPH ( 220 KMH ) . I want know if is normal , I have reset ECU and NO gain. Please if you have test your top speed ? a much top on your g35 X ?

 

My top speed has been about 100mph. Why would I want to go any faster?

 

Only 136mph? Do you live in Germany or something?

 

same as cale^^. I don't go to a track and the Autobahn is not very convenient, so why endanger others to test it And also I wouldn't want to lose my license if I got caught.

 

I live in nord of quebec canada. I test on rural way with a long strip as 2 milles ( no curve ) in my aera we don't have few patrol ( police ) ........ I test in automatique and manual select shift . If I understand my top end is OK for one AWD ????

 

I would definitely take your car in. Tell the dealer you cannot believe your car is only capable of speeds of 135mph. Its an outrage to tell you the truth...

 

Yeah. Something's definitely wrong here. It should be covered under warranty though.

 

wow you're all so pussihurt about 135mph on a rural road where theres nothing around and you can see an oncoming car from about 2 miles, i dunno but 135 isnt that fast it gets up there pretty quick and will slow down pretty quick too

 

Il faut a peu pres 20 mille KM pour que le moteur se relache un peu pour produire les chevaux qu'il faut pour faire 235 KM/h.
Le mien a gagne +/- 15-20 ch et j'ai 18,000 km.

Bonne chance.

 

zamknij ryja pizdzielcu, ja bede jezdzil samochodem jak mi sie podoba ty idioto

 

ChicagoX . Je vais commender moi aussi un spacer 1/2 " motordyne. Avez vous une amélioration avec ce spacer ?

 

The X is quite possibly speed-limited at 135 because of the OEM all-season tires that are meant for safety, not speed

 

Il y a des gens qui ont dit qu'il ne marche pas sur les '05, mais les tests que j'ai vu ont gagne 8 ch minimum. Les '04 gagnent un peu plus, environ 10-12. Je l'aime bien. C'est une bonne modification de mon cote. (excuse, mon clavier n'a pas d'accents)

I wonder if the Canadian cars had different limiters.......hmmm.

TBone--good idea. As soon as I can find a school zone while it's raining, I will test the theory.

 

I Agree.

 

The stock all seasons that came on my X were a V-rated tire which means they are rated to 240 km/h or 150mph, so why would they set it at 135.
