got my dyno graphs today :D

[bradc]

only took a few months

It makes 227.9kw at 5332rpm, and 435.7nm at 4213rpm, both at the wheels. Makes about 210kw at 6500rpm too

Plugging those numbers into the dyno sheet that a UK member made after the UK dyno day, I've got 401.4hp (299.4kw), and somewhere around 550-570nm torque at the engine.

Also interesting to note, I make 0.5 bar by 2350rpm, 1 bar at 3000rpm, and thats about it! I thought he would have taken it higher, but the max boost is only 1.1 bar. It stays above 1 bar all the way from 3000rpm to 5200rpm, at 6500rpm it is still at about 0.9 bar.

Trying to take pics with the camera is useless, I'll put up some scans later on.

It's inspiring for me also, I should be able to post what I get out of mine in a couple of weeks.

ohh and other interesting things to point out:

A stock VR-4 is rated at 363nm at the engine, my car makes that AT THE WHEELS at 2700rpm all the way up to about 5700rpm

When my car was stock it made 154kw max at the wheels at around 5500rpm, it now makes that much power at about 3200rpm!

 

[2000VR-4]

Thats a cracker Brad, well done mate
<<<Very impressed

 

[VR-04-TT]

What psi boost are you running too brad?

Edit: I missed the post where you mention it lol *slaps forehead*

 

[Guest]

Far out, thats incredible!! Well Done !!!

 

[bradc]

1.1 bar is the max as on that graph. 210kpa = 2.1bar absolute = 1.1bar. So 190kpa = 0.9bar

 

[Guest]

thats awsome.. im getting excited.........

 

[Guest]

Right so about 13psi, thats double the stock boost!

 

[bradc]

it sits at 1.1 bar for a bit, so about 16psi

 

[jungle]

Great result brad on stock turbo's
Any pictures of your dump piping?

 

[bradc]

have a look on cvr4 in my gallery

http://www.clubvr4.com/forum/vbpicgallery.php?do=view&g=7

There is one picture of them, doesn't show the front one but does show the back one.

 

[Subaru ETA]

Right so about 13psi, thats double the stock boost!

UC (a clubvr4 member) runs 19 - 20 psi spiking higher IIRC. yet only makes like 190kw ATW. he has custom piping, Link ecu, external wastegates etc. id really like to see what his could do if it has a decent ecu and cat removed

 

[Guest]

now take it down the 1/4 mile!

 

[bradc]

yeah I was a bit surprised Gary didn't push the boost a bit higher earlier on, but the car really doesn't need it

Mitch - it's on the cards

 

[bogan bob]

nice work Brad!

Is anyone else on cvr4 pushing that power or are you the benchmark?
