For All the 10 second GTR owners...

Erik - you already know that your times are being caused by your tires and the consequent crappy 60 foot times you get...your traps put you well into the 10's.

He is correct about our strip - the track prep is hit or miss and one old dude really gives us hassles for a roll cage (all of the sudden and not for the US cars - as a TT Z06 ran low tens and had no roll cage last week).

That said - with the air cooling down, I guarantee LBC will crack well into the 10's IF he gets some real rubber and reduces his 60 foot average from his existing 1.85-1.9 to 1.65-1.75.

When I did my 10.96 I had a 1.764 60 foot - my best ever. Every tenth on the 60 is worth about 2 tenths at the towers - so one more tenth at the 60 gives me about a 10.7x which is what Diveextreme (when he had my setup before his insane R1KX) did in Florida.

Erik - get the rubber and go on Wednesday when Bill isn't there. Plus let me know when you do...

Hey Guys,

I was just wondering how your gearboxes are holding up with the increased launch control rpm (3800) and the extra power over standard with the exhaust and tune. Has anyone had any issues and what are your thoughts on using the launch with that power and what lifespan the gearboxes have. Did you guys use the launch control to achieve 10s with those mods mentioned?

Also do you know did the alpha 9 gtr get a 9 second pass with a standard untouched gearbox and also sleepdoc's gtr or did they at least upgrade the 1st gear etc; and were they running the stock 20inch rims on the stock bridgestones? Help with best tyre pressures would be great to.

I have just put mines dumpipes and a hks midpipe and a cobb tune v6 and am in the process of getting a ti catback. Just trying to work out how the gear box holds up with the increased power.

Cheers
