I'm talking about you driving it in 5th gear numpty, when you drove it you took it just past 6k in 5th. In any other gear it has to be taken to 6.5k without a doubt (and you did). It leans off after 6, thats why I got ya to let off.

172mph was worked out using the gear ratios etc.

7.2k on 215/40/17 would be 174mph providing it could pull to that rpm in 5th.

i have had 145 in most of my et powered s12s running approx 225bhp or more.(this is with 17" wheels so bear in mind with the speed reading)

I blew a hole in a piston of my t3 blowered s12 when i took it to 140 then started slowing down. I believe the std Fuel pump could not supply enough fuel.

My det is going well. i get around 75mph in second gear as the rpm limiter is at 7k .once the limiter is increased i should see 80-85.This should be a more accurate reading as i have 15" wheels now

When i spoke to Den at trax last year (det s12) he said he had gone into the 170mph+ area that day (private road obviously )

hello peebs,
Shawn is correct i did kick some skyline arse that day, allan could only manage 133 on the 1.25 mile stretch and i did 137.9( with a fooked motor aswell) and i rubbed his nose in it by holding my ticket infront of him as he was talking to one of his skyline buddies

I reckon shawn , the power you'll have out of the beast will pull the limiter in fifth.
I have seen the the end of the 150 mph on my private test track of coarse,
have a speedo shot somewhere will scan it , that will make everybody smile.
With the correct conditions, i reckon its possible.
