they arent bolt ons lol Definitely not the ones Joe showed me thats for sure.

Those were my twins. . .I split the setup (twins/manifolds) and sold it. . .

Precision doesn't offer the rb26 specific turbine housings, you can purchase the 4828's without their hotside (-$100), but will have to buy the 707160-5 housings and throw them on the 4828's. . .as far as piping goes my plan was to fab up some hard pipes all the way. . .

Guys this tread is wary too long, maybe this needs to be closed and a new one opened as i know theres new precision turbos out so makes the start of the tread useless.

Anyways i currently have a td06 25g that puts out 320kw on 18psi full boost is around 4300rpm. I want a precision turbo equivalent but with more response as i feel the td06 is a bit laggy. Also on e85 i hope to get at least 360rwkw :DD so which precision would suit me ? I'm confused with all these numbers..

ALSO i want to low mount it for stealth

HKS 7071 :)

The two sizes relate to the "visible" size of each wheel, ie compressor inducer and turbine exducer. Puts things into perspective when you consider a PT6466 flows more than a T51R Kai, and even a FP Super94 HTA (aka, FP6768) is a fair bit smaller wheel wise while being capable of T51R SPL flow

Are you using compressor maps to compare flows and pressure ratios? .... :P

Haha I was wondering if I would be called on that :-P I'll eat my hat if someone can show an unmodified T51R Kai making more power than the highest power 6466 setups, but yeah I was perhaps making a tall call on the Super94 haha... In all fairness the T51R SPL probably has an outright edge, just there is a fair chance of 90pc of people who use them won't see ever make good use of it.

Highest ive seen with a T51R KAI on an RB26 was 603awkw at 30-32psi.

That's the one with the upgraded compressor that ran at JEM? But yeah, folks have gone over 600kw in Oz with 6466s - bigger numbers in the US but obviously dyno comparisons get a bit iffy :)

Aggroman - there are others that make that sound too :D But yeah, safe bet with a T51R.... it's one of the things that disappoints me with the Precisions, they all sound pretty run of the mill. Yeah, I let the sound influence my turbo (and other parts) choices :teehee:

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
