Good to see you have a win mate. it will be so very sweet now. How does it feel on the road?

[wrxkilla]

hehehe

nah seriously, car doesnt get driven around town, i have a charade for that, this is for racing

[TommO]

Well done mate... I went in your car with 250kw and it was crazy with it's fun powerband, hate to imagine how physco it is now

Awesome result!!

Tommo.

[wrxkilla]

yeah powerband is fine, when flogging it stays on boost so its great fun.

[Col-GTSX]

welll its attracting extra attention....

Would love to be a passanger for a full boost run....

Great work once again

[wrxkilla]

hehehe

yeah

well hopefully if us qld mob have another meet soon we can arrange something!

[Morgs]

Looks solid. Let us know how the MPH goes.

Surprised it too so little boost to achieve that result.

[wrxkilla]

yeah for sure, i was expetcing to need a little more boost for 400kw.

but im happy obviously.

it has the 0.96 exh side thats more top end etc.

for the track no cat (as on dyno) 4inch exhaust, 60mm hks gt wastegate, mani, strong motor with head work and mild cams.

it done many runs, all over 400kw once tuned etc.

[Morgs]

Only thing I'd be worried about is the lack of midrange versus top end. Still pulling at 8k pretty hard there.

[wrxkilla]

yeah defo

like i say on paper, it shows little mid range etc and doesnt look the best tbh.

but on the street when going hard it stays on boost so thats all that matters from my standpoint. keeps pulling through all gears.

really a 9k rev limit might help out as the turbo really looks like it wants to keep going hey...

Excellent result. Another Big HP R32 'R to hit the strip

Have fun and best of luck with it.

[Tommyk]

Cant wait for the results from the strip.

Would like to see what these big singles can do at the drags.

[wrxkilla]

wont be easy, but thats the goal

thanks all

I thought I might have a bit of fun with this power graph using a couple of data logs that I have seen recently as a basis. What the following numbers do is simulate what it would look like if you have a video camera pointed at your tacho during a perfect run.

1st gear average power assuming 5,000 rpm held at launch

8,000 415 rwkw

7,500 410 rwkw

7,000 380 rwkw

6,500 340 rwkw

6,000 275 rwkw

5,500 200 rwkw

5,000 140 rwkw

Total 2,160 rwkw

Average 309 rwkw

1st to 2 gear average power assuming 2/10th second gearshift

8,000 415 rwkw

7,500 410 rwkw

7,000 380 rwkw

6,500 340 rwkw

6,000 275 rwkw

5,500 200 rwkw

5,000 140 rwkw

Total 2,160 rwkw

Average 309 rwkw

2nd to 3rd gear average power assuming 2/10th second gearshift

8,000 415 rwkw

7,500 410 rwkw

7,000 380 rwkw

6,500 340 rwkw

6,000 275 rwkw

5,500 200 rwkw

Total 2,020 rwkw

Average 337 rwkw

3rd to 4th gear average power assuming 2/10th second gearshift

7,500 410 rwkw

7,000 380 rwkw

6,500 340 rwkw

6,000 275 rwkw

Total 1,405 rwkw

Average 351 rwkw

Average of all 4 gears = 326 rwkw

If the above result is actualy achieved you are looking at an ET of ~10.6 seconds with a TS of ~210 kph. If you can speed up the gearshift by 50% you are looking at an ET of ~10.4 seconds.

It will be interesting to compare the actual results after you have had a couple of runs.

Cheers

PS; I have assumed standard R32GTR gearbox and diff ratios and a tyre circumference of 2,050 mm (ie; = 245/45/17).
