Head on over to ls1tech.com they have an entire forum dedicated to dyno guesses and bench racing.

The real answer is "What mph does it trap?"

so... go do that obviously

Yeah, that's the plan.

Need better tyres than the Achilles that are currently on it though.

Whilst mashing the pedal and doing mad skids is fun, having some form of traction would be preferable.

Currently the thing spins at the drop of a hat.

In saying that it hasn't had a wheel alignment yet, so there's that, the tyres seem to using all the tread though.

Meh

In other news, I'm loving your build thread, I'm looking forward to seeing how your engine goes.

My engine is all up and running! This is why I said 250kw (maybe less due to auto lyf, 230?). If you DO decide to put a cam in, make sure that you get a cam that doesn't get max lift beyond what the heads will flow.

Thats effectively my current issue with my motor, the cam gets .600 or so lift, and has a ton of duration, but the LS1 heads (mine are OEM, just skimmed for more compression) make their max flow at something like the below

As you can see, it tapers off pretty bad, so bigger cams just trade low down power for higher up power, but the heads can't supply them, the cam can have as much duration and as high lift as you want, but there's very little benefit, unless you really work the heads/intake to actually get air into them.

Which you can do... but it's well worth having the information and a plan beforehand before $ gets spent.

In other, non-witchcraft related news...I have some Hankook Ventus S1 EVO 3 tyres getting fitted tomorrow.

245/35 19 and 275/30 19, should grip better than the current Achilles rubbish.

4 speed autos I don't think lock in the commodores...?

they do in 4th. When tuning with HPtuners need to "activate" lock up but can have trouble staying in lock up mode on a chassis dyno.
Good result from a"standard" ls1. So when is blower being ordered?

Definitely lock. You can command them to lock using hp tuners. Force it to stay in 3rd and lock converter is what I and others I know do, but Wether  that's normal who knows.....

    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
