Kickass!! this should be posted in the dyno graph thread.. unless you had way more pics of engine bays or some damn dyno vids!!! :frage:

 

[Mr. KDes]

Fuel and IM on the last car?

Nice on that Z1 :up:

E85 Fuel , ID 2000cc , Walboro 450lph Intank

Stock RBC and TB

:nod::worship: Love the power that z1 is making. Holds hp and tq like a champ. What's the fuel pump setup consist of on that z1 setup?

 

[SPL Dan]

Added a lil Turbo Fuel system info to the original post . Note the 590WHP Z1 is maxxed out on the duty cycle on those ID1000cc on that pass turned it down to 570 for saftey

 

[BoostedEH]

Good numbers!makes me want to throw more boost on my setup.

 

[w00t692]

Those turbo's spool slow as shit. A gtx3076r will make similar horsepower and spool easily 800 rpms sooner and hit full boost much much sooner.

I wish people would not just assume a big ass 6266 or 6262 will be what they should use and look into newer turbos that are out there now...

my 6262 come on at 3k rpm....on low boost u can hear the wastegate open by 3500rpm.....put down power fast...hard to drive almost....any sooner u would think I would loose top end

I love my PTE 6262.....best turbo I have ever owned

k24 frank spins to 8400rpm

 

[BlueHatch]

nice! get to work weather is perfect in FL you should be at the track

 

[josh2man]

what was the duty cycle on the 450lph and id2000 on e85 and the base fuel pressure ?

Making a bunch of torque early on the stock rods isn't the brightest idea.

The thing all the highest-powered stock engines have in common is a late-emerging torque curve, and for good reason.

Some power for stock bottom ends

Eh that's a k24, i don't have issues with that turbo in a 20% larger motor.

I completely understand this concept, have you ever seen a diesel engine connecting rod? Absolutely beastly thick and strong. This is why lots of stock turbo mazdaspeed 3's with full bolt-ons and tuning bend their rods due to torque coming in very very early on (under 3k rpms).

But here's the thing, it's not coming in THAT early, and coming in hard and strong is a shock to the rods at any rpm, whether you ramp up by 300 ft/lbs of torque at 5k or 4k it's "bad".

what kind of clutch are you using?
