Nistune Forums

Any of you guys like to race you're street cars?http://www.youtube.com/watch?v=EgMZIG79wCU

We haven't had a drag strip here for some years now.

But the biggest I've done so far (about to be beaten by an SR20!) is actually Matt's R34 with 300rwkw. Which is around 500 crankshaft HP. Not bad for a unopened (except cams) daily driver with factory street manners!

I know Trent in Melbourne has done a 400rwkw SR20 using NIStune. That one was a bit special though - not your average street engine. 2.2 litre stroker on E85. Running Z32 AFM - maxxed!

Wondering how much boost to make such power ?

Not sure but it'll be a lot!

PL

Upwards of 28psi would be a starting point.

I'm still waiting for somebody to chime in with the inevitable "I put a GT6041 on my Nissan Micra and made 800hp" post. Come on guys!!!

PL

running approx 480hp (at fly) @ 1.7bar

black top sr20det
HKS lined block w/ 90mm HKS piston / eagle rods
stage 2 BC cams
squish removed head
850cc Sards
mazworxs top mount with gt3076
z32 AFM

think there's more to come but just need more time to play with the tune...

im proud to say i own nistune now. thought you guys were all disco potatoe t28 guys. I always say you're not making real power till you're making 100 horses a cylinder. Im making 490 at the wheels race it at 465 470 horses doing 6.7, 6.8 depending on track conditons. best E.T. 6.6 at i think 104 or 106. 22 psi e85 74mm borg warner t4. i launch at 6500 rpm. i think making alota power on stock motor is like the real estate bubble in the us its eventually gunnah pop. even worse when daily driven. But why limit you're self with a stock motor, but i guess thats fast enough for the street. we have a few 700 and change ka's here, but they will probably break at the track.

What fuel are you running at 1.7 bar ?

Hi
This E.T. is on what track length ?
Best regards

What fuel are you running at 1.7 bar ?

shell UK V-Power (99 RON). I run approx 4-6deg @ peak torque without knock.
keep in mind i run a sr20 with the squish area removed so its low compression. I dont have my calcs to hand but its less than 8.5:1 when i built it.

Hmm,

my highest horsepower SR20DET so far is 621hp/623nm at flywheel.

Then there are some higher power Skylines and Z32 but it much easier with 6 cylinders so those don't count.

6 cyls count. as long as its on nistune. 6's on 1/8 mile don't know what it does in 1/4 mile. Not street driven. Would be kindda cool to think of nistune as serious performance product capable real results, on a competative stage. Go hard or go home!

I'm at 425whp with my L28ET. I've also tuned L28's into the 500's with nistune. I think 6 cylinders can count if they only have two valves per cylinder.

415rwhp with GT3071R @ 1.7bar on a CA18DET and 1200cc injectors with E85 fuel.

now building more usefull version with a GTX2867R turbo
