Quite happy with the 12.6 sec with a terminal of 128mph just wish I could get it off the line better i'm sure I could get an 11 second quarter then.
Rich

 

Nice one Rich, Terminal's not bad either, must be near on 500-520bhp now then??

 

Not shabby Rich, as Pete said nice terminal, time to play with tyres maybe? And take your shoes off!

 

Yep it made 516 bhp on the rollers, still have issues with back pressure looks like it might be the manifold.
Rich

 

Once it's going it ace, 6 degree beam going on next week, but have to wait till next year to see what difference it makes as the was the last rwyb of the year. Might stick some 888's on too.
Rich

 

good time mate i did a 12.74 in my fiesta but keeps spinning even on 888s good fun tho

 

Nice time mate
What's yer spec these days rich? Still got that monster T66 on there?

 

Great terminal speed

What was your 60ft ?

Steve

 

Ye still got the T66 mate, may well make way for a GTX3076 with a twin scroll manifold in the new year money permiting.
Rich

 

Pretty rubbish 2.252 seconds
Rich

 

Post your times up for your run please, 60ft 1/8th etc

Steve

 

RT - 0.827
60 - 2.252
330 - 6.032
Mid Speed - 98.59
660 - 8.864
990 - 10.781
1320 - 12.628
Terminal - 128.33

Rich

 

How,s that for a good guess mate?? i'm not just a pretty face...

 

Sure you didn't just speak to Martin?
Rich

 

Not at all mate, i've been around long enough to roughly guess power to terminals matey...

If i were you Rich i'd stick with your power now, usuable and fun mate and let's face it, 516bhp isn't shy.. what torque did it make Rich??

 

Ye it'll be staying in it current spec for a while, while I get the floor and shell up to scratch.
Taking it down to Calsport tomorrow morning to have the entire underside done.
Not sure what torque it made i'll have to ask Martin
Rich

 

great terminal speed theres some hp there mate

 

Just wish I could put it down at the start, there was a Skyline there that did an 11.2 but his terminal was 120 mph

I completey bogged down on one run and did an 13.7 but still got a terminal of 125 mph.

Rich

 

Standard diff aswell Rich??

 

Yep standard diff and gearbox both with the same oil I bought the car with nearly 8 years ago now
That will be changed when the underside is done next week, well the oil anyway. Might beable to stretch to a gripper diff depends how the money goes.
Rich

 

Here's mine with about 370bhp

60ft - 2.3140
330ft - 5.8251
1/8th - 8.5801 @ 89.09mph
1000ft - 10.8763
1/4 - 12.9151 @ 114.77mph

You got off the line better than me but must of had lots of wheelspin through 2nd gear.

When yours grips it does shift

Steve

 

This is the first time in this current spec i've been able to really open it up, pulling through 3rd gear is pretty awesome.
Time for some 888's I think.
Rich

 

i think your 6deg beam should help with grip.

 

my 2wd saph got 12.5 a 117mph, with just under 400 bhp

 

and my 4x4 saph got 12.8 at 108 mph on greens

 

Dragging my own thread back up here but I have a question about terminal speeds.

Why is it that I can have such a high terminal speed of 128 mph @ 12.6 and Forevaford does a 117 mph @ 12.5?

I assume he gets better traction with less speed and I get worst traction and make it up with the extra bhp hence the higher terminal.

But Scoooby Slayer has a whooping 900bhp and does 134mph terminal which is only 6mph faster than my 516bhp.

Does aero start to come into it at a certain speed?

Cheers Rich

 

R888s are terrible for 1/4 mile racing, you can't get them hot enough, plus the side wall is way to stiff.

Mph is hp
ET is how efficient you are with the above.

My Renault 5 has run 12.1@110 on slicks and a 1.73 60ft.

The 60ft is the
Most important time for getting a great time.

 

I know different tracks have different grip, but my old cossie running coilovers, 235 40 17 Goodyear f1s and mapped at 380bhp on light blues used to get 12.4 quarters all the time at the pod, cant remember the terminal speed, would have put it on other tracks if some thieving little ***** hadn't broken in and stripped it bare

 

How come a car with nearly 400bhp more is only 6mph quicker over the line thou?
Rich

 

because its a supra that weigh's a million tonne's on shit tyres .

 

About right for 500bhp mine ran 11.8 @ 127mph with 504bhp.

 

Trial and error with tyre pressures matey, free performance gains FTW.

 

So terminal speeds are a good indicator of true horse power?
Rich
