Precision Billet Turbos

This. I'm sure I've seen it but damned it I could find it over the weekend... Spent hours searching.

All I could find was partial pulls and lower boost graphs as well

[jet_r31]

You won't find it..because there isn't one...i spent hrs trying to find it one day to...

Hey guys please see dynosheet just posted (in the RB25 Dyno thread) of my low-powered car..

[Mitcho_7]

Maybe Jez can chuck up kurtis' final graph when he gets the time?

[rondofj]

Just confirmed my suspicision for the laggy-ness, inspected n tensioned my throttle cable to just about touch-tight responsiveness. Doesnt feel so laggy now anymore, got a lot of the crisp touch- responsiveness of my stock turbo back and smiles all round. Very nice street turbo the 5558, mines not so linear but gives an angry meaty kick at 4000ish which is what I always wanted. Still running pretty pussy boost 16-18psi so top end is left wanting..

later go a set of poncams and E85, will be a different beast again

[rondofj]

Ohhh man ur really peer-pressuring me lolz.. was thinking water injection, re-route part-cooler pipe, crank up boost as next mod... And clutch when the stocker shits itself haha. Have you seen my dyno-plot, and any comments? Laggy hey.. Well I only know the stocker's response thats why I keep saying its a bit of a lag-boat.

all of the stuff on your printout is just about identical to my gtx3076 with 0.82 when i had a tune on 98pulp.

Ron its never going to be the same as a stocker. Just be happy with it dude. As JEZ said 4000rpm is not laggy

Is it lighting up second gear in a straight line? Go E85 next..

Hey thanks man, if thats the case then I should be pretty happy that it matches a top of the range Garret..and yes it does wheelspin n skate second gear on 18 inch Bridgestone Potenzas. Third as well if I give it some stick. How much torque did you make, mine comes to 736Nm if that can be relied on. And Kasko ur right, it will never be like the stocker down low but its not far off either

f**k rerouting intercooler pipe..waste of time and money , water injection will fix it, my mates vl i did, 28psi of boost, before intake mani was to

hot to touch, now with 450cc of water in its guts you can touch it fine...

Its one way to fix chinese intercooler problems(eg they make good power and flow well, but heatsoak really easy..lol)

cheers

i was making 641nm, so looks like the two turbo's are similar on that boost, not sure about the housing differences though..

its a good result though, looks like 16psi, probably needs atleast 20psi to really unleash

[rondofj]

Well the ching ching cooler is doin a good job because the outlet pipe up till a bit past the battery tray is nice n cool, BUT once you reach the rad/fan area it heats up pretty quick all the way to intake mani. So I know its not the cooler thats why I wanted to re-route and heat wrap that bit of top pipe away from rad/fan and cam covers

[Mitcho_7]

how much laggier is the .82 5558, is there much real world experience on an rb with them?

[donut_kng]

.

[methz]

u do realise heat wrap keeps the heat in the piping??? ....

[DVS JEZ]

Will post up the dyno sheet from Kurtis's car if he doesnt do it before me.

Sorry have been flat out in the shop.

[GTScotT]

Yours honestly isnt laggy Ron, its pretty decent. Full boost threshold is pre 4000 which is decent. Peak toque isnt far off. It didnt make the 300 you hoped for but then again its close enough.

The result is pretty decent as is
