Cheers

I'll start running around now and see if anyone is open

Thanks power_slide, but I'm working 80hour weeks and don't have time to even take my own car out.

As a guide hub > 6f (cv) > mainline > dd 6f (post 2006) > dd 6f (pre 2006)

If Spiro hasn't updated his software from the old 6f he was using (about 2 years ago) then I guarantee you will get sub 400, and I'd quess a 380-390 on Spiro's dyno.

You can't blindly compare a run with another dyno, unless you know how that dyno reads as a guide, and I've had a few cars on Spiro's dyno with his old software.

And if you go to another tuner telling them that the car has come from somewhere else the only fair way to assess the other tuners run is to log throttle response.

Tuners just love to get new business from other tuners; it's a double win.

My opinion is you will get consistent results from Jim's dyno when mapping mph from his power levels, and I've mapped mph v power using the same dyno from 121 mph to 132 mph. That is mph improvements were consistent with power improvements.

If you take you car to another dyno you will not prove anything other than confirm that those 2 dyno's read differently, and I can guarantee they will.

There is something not right with this run, as it is not consistent with results of others at those power levels with the ZF. I’ve analysed the results of many others guys runs (I have a spreadsheet), and you can tell a lot about the power level from the second half track.

96mph is very slow to half track. You should be at 99 to 102 as a guide.

But slow launch and wheelspin would have contributed.

Your 2 half track time is also off the pace a bit, not a lot. 4.05 instead of around 3.8 to 3.9 seconds that I’d expect. However, your mph pickup is 25.5, where I would have expected closer to 29-30mph pickup at a 420 power level from Jims dyno.

Are you getting full traction on the second half track with worn tyres?

Have you had the car back on the dyno after the convertor was done?

I’d put some MT’s on just to see the difference that makes.

Jim will be back in 2 weeks, and I'm sure would be happy to talk with about it.

Well if you havnt got the right tyres, then your struggling to get the power to the ground. Maybe that's where your losing mid mph and end mph.

[power_slide]

I'm also booked in at Tunehouse not the 12th which was a 2.5 month wait

I had to get the box done and jims been away for so long I don't have a choice but to wait

With et streets I would expect low 11's but I don't see that happening until a retune

[power_slide]

Will a +44 offset work?

Can't seem to find 17x9 with 35 offset

no way 420 there!

lets SAY you somehow get a 1.60 with the zf which is VERY hard to do, that takes .8 sec of your 1/4, givin you about low 11s. a BF with 390rwkw and a 1.66-1.74 60" should run a high 10. you with 421....easy 10. Try go to a non hub dyno and watch the numbers drop through the driveline.

I ran R/T .736 -- 60' 2.081 -- 1/4 mile 12.0 -- Speed 197.5 km/h

with my hub dynod 349rwkw.

So does that mean I ran a 12 dead with less than 349rwkw?

seems you got mid 11 in the car crozza and improve on tha 60".

power_slide, just do what we alldo, get stock xr6 rims 17x8 and put 275/40 (or 45?)/17's MT ET streets on them. Big burnout at the start and off you go! See how much better your 60" will be

no 38 offset max taleb have the right wheels 44offset is to far in

[power_slide]

Are 17x10 available?

If I'm spending on rims I want to do it right
