Thread: T25 Boost Response

Your Rangie runs an Isuzu?

It certainly picks up quick, engine speed and boost.

Looks to hit a max of 16psi, bet ya that makes the Isuzu fly.

Was it in low range?, looks like you're doing all of 10kph! I seem to remember long ago, one of our southern neighbours from down your way reckoning he could spin all four in second on the tarmac, coincidentially it was also a suzi equipped Rangie. Now I'd like to see that!
Maybe it was a load.

My speedo is currently playing games, but 3000rpm in second high is about 40km/h. It can beat most ricers until I have to change gear.

It was running 20psi boost, so I've either got a wastegate issue or a clogged line to the boost gauge.
With 20psi it has traction issues in second on dry tarmac and third on wet tarmac. It's good fun.

I still call BS

Maybe when you fit your intercooler, upgrade the 2.25" exhaust, put one of the other turbo's you were going to fit

You should turn the screws and find out for yourself.
I'm not going to put up a video of squealing wheels on a public road, the police have been known to use them against people.

i had mine out half a dozen turns, more than its 2 3/4's it is now, it ****ed black smoke, absolutely flew...in comparison to normal and the pyro flickered around madly!

Yet.....no wheelspin, or becoming loose to drive on the dry asphalt

Email it, I'd be quite happy to watch then destroy, put up or....

You don't also have a stock 5L VN commodore capable of 13sec 1/4 mile?

If you've got black smoke then you don't have enough boost. Once you're blowing black smoke you're going backwards. Mine runs cleaner than your average 1KZ surf or hilux.
What size tyres and gearing are you running? I'm on 29's, 1.003 transfer, second gear is about 3:1, 3rd is about 1.6:1.

Commodores, never.

Well aware of black smoke, 17psi, maybe when I fit the VNT and 25psi I'll be burning up all 4?

Don't care about theory, proof!
