Maybe, no idea. I make about the same. About 500 bhp at 6psi but that was about the highest before knock would occur at high rpm. Jez at Horsham Development tunes safe and knows a bit about turbo 350Z’s too. My 370Z AAM TT was the first though.
I do realise that our bhp and US whp are about the same. Power is good. I’m just puzzled by the high boost

Forced Induction Finished Builds
 

He probably pulled a bunch of timing. I’m running 11.5-12lbs with the output most get from 9ish. We had to do that to limit the torque it was making. I wanted to keep it under 450wtq and it was a torque making monster.

First pulls were 500/480. We finally got it dialed ‘down’ to 510/440.

Hmm, i already make 435 tq with my tune at around 3700rpm. But at this point boost is up to 8psi instead of mentioned 6psi (at peak power). Hence, i’d acrually not want any more boost anyway, right?

I’m not familiar with tour setup, so I can’t say. I have a BP single kit, which a single makes torque for days. I also have the P6266 turbo and not the new oil less turbo. A TT is a little easier to dial the torque in. Key is to find a good tuner and tell him exactly what you are looking for in your tune. If you trust him, which you should if he is tuning a $15-20 turbo build, then let him work it out and don’t worry about how much boost you are running.

I finished this FI build with the old GTM kit, here are the results! Tuned by me, on 93 octane. Ran out of fuel uptop so unfortunately had to limit rpm.

This is with a returnless fuel system and 700~ cc injectors.

Yeap, more timing creates more cylinder pressure and more TQ.

And heat, can't forget heat. That's when the machine starts to get weak and everything starts to fall backwards like a runaway nuke meltdown.

It is where you place the heat. Less timing, the EGT's are going through the roof and the heat in the turbo is more. More timing, the heat is in the cylinder with more cylinder pressure. It is a trade off and a fine line to walk.

Wishlist and to-do:
I looking to DIY an ice water intercooler spray utilizing another set of windshield wiper jets and second reservoir in the hatch.. going to test and see what happens :yum:

Looking to get some ABS sheets and make a semi-full body undertray based off the gtr underbody with naca cooling cutouts...

Dif cooler and upgraded dif cover needs to happen at some point... may mount the cooler behind the license plate.

Transcooler also... may haedline it too the dif junction and run a second cooler behind the license plate.

Engine build is a wishlist item... after the stock block starts to get tired.

BC-DS coils after the OE suspension on swifts has had enough :)

And whatever elase comes to mind :happydance:

Anyone in here over the 1k whp mark?

No, very few have ever made it (4) and only one is still running.

Do you know who the one person is that's still alive and running?

SOHO's shop car Nismobae. That's it at the moment.

And what's your excuse? :stirthepot:
