Mods?

Its the 373 Diff with diff gears inside i have Nittos all around w/ 275's in the rear.. the last i looked i was about to hit about 5400 rpm, Im running a 1j with a gt40 and an emanage.. full exhaust front mount afpr .. the basics.. The gears are hella long man...

275/40/zr17 The diff isnt stock... the gears are diff.. it was the 89 diff..which i believe is a 373 gear ratio...but that wouldnt matter.

5400-4th-275/40/17-3.73:1 diff = 106 mph

No, the gears in my diff aren't stock as stated before lol.. Im not bull shitting tho there was 1 guy in his car and 1 in mine.. the car was a track car built by tps w/ a 7M.. I purchased it pulled the 7m out dropped a J and thats the fastest ive gone.. unless the g35's speedo is off also haha...

 

[modmonster2008]

does going 70mph count? lol haha j/k


ive gone 110 on the freeway before, kinda scary especially when theres SUDDEN traffic

Ok giving you the benefit of the doubt and assuming you have a set of the ultra rare 3.2:1 Group A race gears in your diff it becomes

5400-4th-275/40/17-3.2:1 diff = 124.3 mph

(I wouldn't tell the 150mph story anymore it makes you look a bit dumb)

well im not going to go and argue about it because i dont have any hard proof.. Im going off of what the g35 guy said :dunno: i told him i still had 2000 rpm n 5th gear left n he got angry ... lol

The numbers don't lie.

 

[Supra-Man18]

The numbers don't lie.

Ill try it again some day.. ill just need some one with an accurate speedo next time i guess :nono:

 

[IJ.]

Take a GPS, it's not 100% but it's closer than most speedos.

I have independent wheels speed sensors on all 4 wheels and use the GPS to calibrate them to be as accurate as possible, my stock speedo is KPH out at the moment due to a Diff ratio change but even when it's reading 100 kph/100 kph GPS it's still out when above 250 kph due to tire growth and mechanical drag in the cable.

 

[Supra-Man18]

damn 4 wheel sensors ? thats bad ass.. How did you make that work ?

 

[03bamaGT]

Yea just use like a road GPS or have the iPhone haha.

It's part of the MoTeC traction control.

im at 3000 RPM at 60mph with 4.30's and a W58, you must have a different ratio or tranny?

My fastest in my N/A was 110mph, got there pretty quick and felt stable, about 5500rpm I think, dont remember.

Ive done 160+ years back, when my car was open stock dp 7m. Went past redline and stayed in it for alittle while racing a is300. Also melted my ebrake cable that time.
