I have questions that if answered may cost me a fair bit of money so please don't respond.

Do you have a photo of the turbo on the T88 kit, I also have one but scared of the clearance of the massive EFR?

Do you have a graph from the hubber, although a 9180 on a 2.8L it might give me an indication of similar of a 9174 on a 2.6L?

How can a camera even record at 240p? haha

I posted a graph a page or so ago It's kw at all 4 and not all in, he was aiming for 600kw and stopped there for pity for the transmission haha.

Urgh, running out of excuses haha

I did look at that graph but hard to decipher with the dyno doing wierd things as you mentioned with the torque. Video does look nice and responsive though

It the weather is ok I'll be going for a strop in it next week, will try and get some kind of evidence of what it's real world boost threshold is like

Not much room there at all!!! Less then with the 6 boob manifold.

Because everyone likes photo's.. this is not my car so details are only 95% accurate.

Nitto 3.2 EFR 8374 1.05 twin EXT gates

~23.5psi back to 21-22 up top on E85

480rwkw (possibly slightly over spinning the turbo but not sure. 6 Speed getrag

[burn4005]

wow 600kw of E85 and the little nismo fuel reg is keeping up!

is it using a variable speed pump?

lot of power for 'only' 23 psi

curious to know whats done to head

Standard size valves, standard cams

It's a 3.2. It's going to swallow air alot easier then a 2.6.

Thats 2 3.2/8374's that have returned pretty much the same power for the pressure used.

Got a speed sensor yet?

Turns out Full-Race wanted to share this clip so made an effort and got a higher res version of the 9180 R32 GT-R at Hampton downs, in case people wanted to see it with more than 48 pixels:

2.6ltr or 3ltr?

I put all the spec in the video,  it's a 2.8

3.2 should just bring it on earlier.  2.6L should still make same peak power if revved hard enough

My gate pressure was approx 21 psi and mine mad 390kw on JEMs dyno and then 500kw on 31 psi on a freak run (call it 490kw) so it is  roughly 9kw per psi which is why 480rwkw on 23 Surprised me.

Rw to awkw could make  diff.

And no on speed sensor. Been flogging it on 30 psi as it is

I didn't know Mr Brooking went single turb......finally got rid of those shite boxe Tomei twins!

.....looks scary, needs more 4wd controller.

Pay more attention in my group on Facebook sir.  There was a discussion about the potential change, then on a suitable EFR, then dyno results etc

[Sub Boy32]

Been busy.....subframe swaps and shite ?

Will look back at past topics on FB.

The 3.2 might be running high compression which would help it make decent power even at relatively mild boost.
My makes over 525kW at 26psi - RB2530 10:1 not running an EFR though.

Fair enough

Finally got my hands on a 34 GTR tail shaft.

Going to do the 34 GETRAG conversion while retaining r33 GTR diff gears for even shorter gear ratios.

8374 with even shorter ratios = super responsive street car

Come to our next track day in September, real men race on the track not the street
