Just got my self another gtr after regretting selling the other.

Always regretted not launching it after the horror stories about weak gearboxes.

Any what revs can i safley launch at on a standard gearset?

Car has a single Gready T78, cams, fcon pro gold, oz giken clutch, uprated rear diff ,etc etc shoud be good for 500bhp

On the rollers tomoro so i will confirm bhp and torque :thumbsup:

1. Make sure engine is warm
2. reach down and make sure you have a pair
3. Throttle the Beast real good
4. Hold at around 7500 RPM
5. Pop the clutch and hold on
6. Tach to 7500 engage clutch, and SLAM second
7. Hold on
8. Tach to 7500 again, engage clutch, and SLAM third
9. Hold on
10.Tach to 7500 again, engage clutch, and Slam Fourth
11. Hold on
12. Tach to 7500 again, engage clutch, and SLAM Fifth
13. Hold on
14. Bring car to a stop, get out and change your underware as you have for sure pissed your self, return car to wear you stole it from, get in your Fiat and go home.

Ok funny guys i know but i just wondered how much pain theyd take as many people seem to break gearboxes, problemo is i aint got the money to break a gearbox, so wondered what sort of revs the standard box takes?

car produced 535BHP today but had some major issues with getting air in (single HKS mushroom filter Sh*te) and overfueling and minor ignition misfire, problem was he couldnt play with the fcon.

No problem with launching off the rev limiter with stock boxes and running mid 1.4 60fts, 3rd is the weakness, not 1st or 2nd.

You should be fine, so long as your not abusing it all the time.

You'll need atleast 6500rpm as Ive found less than that it try's to bog, not sure about overs but my 2 R32's needed 6500rpm
