Why is there a dip on your dyno sheet at 5700 rpms?

Actually that is about right for 17psi on that turbo...
Is it BB or regular?
Can you post pics of your vmount setup, please?

Let's ask the question a different way. As a professional tuner how much power would you expect to gain, for the same boost from the first rough cut on the dyno to an optimised fuel and ignition map?

This was done by a friend of mine in Japan, 13bt bridgeported T51 spl, on pump gas.

LUPE

What's PS? We need HP numbers

marix1521

any estimates on high boost? such as 25-30lbs? i would like to see a BB dyno as well. when do you hit full boost BNA?

sillbeer

PS is only like .03 off from HP or something very insignificant. Find a conversion calculator and figure it out. I don't fill like it now. Also pump gas in Japan is a higher octane than what is available here in the states at the pump. 100. Hi-oc is all I used while I was there.

theirs is ROM ours is RON. the gas is as close to the same as you can get.

BNA_ELLIS

air fuel ration too rich but din't have time left to sort it. at the dip it's 9.9:1

BNA_ELLIS

Non ball bearing turbo.
Excuse teh engine bay a bit of a mess as I was out of time to through everything together.
I will post dyno in a couple of weeks at 25 psi when I finish it off.

Maxthe7man

Their gas is ron, although some of their pumps do for some reason say m+r/2 on them, which is what we use in Canada and the US for rating as the PON, it does work out to a higher octane, about 95.8, this car had a pretty safe tune on it, it was tuned for good power with safety in mind in case it got a tank of crappy gas, it would make the same power on regular, it would also make alot more power on race gas, but street driven 600 hp in a 1000 kg guttted fc is probably enough..
T51r spl is a pretty wicked turbo...

3RotorRocket

what psi was that at? I want that turbo bad.

LUPE

Yeah, I'm going to upgrade my Hks T51R KAI wheel to a SPL wheel. It's only $120 for the upgrade.

marix1521

what is your ET and speed, LUPE?

BNA_ELLIS

Full boost at 5500 rpm

LUPE

slow @ slow.

Pressurized

do you get the wheel directly from HKS? that sounds like it might be a good idea. i still need to get a good "tune" on mine.

marix1521

oh come now. it can't be that bad...

LUPE

No, I doubt HKS would even sell it to you. I get them directly from Garrett.

BicuspiD

Wow those dyno charts look great for a drag car, but do you guys actually drive these on the streets?

How can you live with no power until 5K+Rpms?

LUPE

It's all about how you drive it. I can out spool stock twins any day. I just have to keep the engine high in the rpms.

BNA_ELLIS

It's fine on the street only thing that i'm worried about on the street is the noise.
It's really far too loud for built up areas.
It's fun on the road lag is but for a moment.
